Perioperative myocardial infarction is an underdiagnosed complication causing morbidity, mortality, and considerable costs. However, evidence of preventive and therapeutic options is scarce. We investigated the incidence and outcome of perioperative myocardial infarction in non-cardiac surgery patients in order to define a target population for future interventional trials.
We conducted a prospective single-center study on non-cardiac surgery patients aged 50 years or older. High-sensitivity troponin T and electrocardiograph were obtained five times perioperatively. Perioperative myocardial infarction diagnosis required a significant troponin T release and an ischemic sign or symptom. Perioperative risk calculator was used for risk assessment.
Of 385 patients with systematic ischemia screening, 27 patients (7.0%) had perioperative myocardial infarction. The incidence was highest in vascular surgery—19 of 172 patients (11.0%). The 90-day mortality was 29.6% in patients with perioperative myocardial infarction and 5.6% in non–perioperative myocardial infarction patients (p < 0.001). Perioperative risk calculator predicted perioperative myocardial infarction with an area under curve of 0.73 (95% confidence interval: 0.64–0.81).
Perioperative myocardial infarction is a common complication associated with a 90-day mortality of 30%. The ability of the perioperative risk calculator to predict perioperative myocardial infarction was fair supporting its routine use.
Unsatisfactory weight loss after gastric bypass or sleeve gastrectomy in super-obese patients (body mass index > 50) is a growing concern. Biliopancreatic diversion with duodenal switch results in greater weight loss, but is technically challenging to perform, especially as a laparoscopic procedure (Lap-DS). The aim of this study was to compare perioperative outcomes of Lap-DS and the corresponding open procedure (O-DS) in Sweden.
The data source was a nationwide cohort from the Scandinavian Obesity Surgery Registry and 317 biliopancreatic diversion with duodenal switch patients (mean body mass index = 56.7 ± 6.6 kg/m2, 38.4 ± 10.2 years, and 57% females) were analyzed. Follow-up at 30 days was complete in 98% of patients.
The 53 Lap-DS patients were younger than the 264 patients undergoing O-DS (35.0 vs 39.1 years, p = 0.01). Operative time was 163 ± 38 min for lap-DS and 150 ± 31 min for O-DS, p = 0.01, with less bleeding in Lap-DS (94 vs 216 mL, p < 0.001). There was one conversion to open surgery. Patients undergoing Lap-DS had a shorter length of stay than O-DS, 3.3 versus 6.6 days, p = 0.02. No significant differences in overall complications within 30 days were seen (12% and 17%, respectively). Interestingly, the two leaks in Lap-DS were located at the entero-enteric anastomosis, while three out of four leaks in O-DS occurred at the top of the gastric tube.
Lap-DS can be performed by dedicated bariatric surgeons as a single-stage procedure. The use of laparoscopic approach halved the length of stay, without increasing the risk for complications significantly. Any difference in long-term weight result is pending.
Relatively little is known about the risk factors and treatments for postpancreatectomy hepatic steatosis.
The records of patients who underwent pancreaticoduodenectomy or total pancreatectomy between 2005 and 2010 and were followed up by periodic imaging were reviewed retrospectively. Risk factors and treatment for postpancreatectomy hepatic steatosis were analyzed.
A total of 253 patients were included in the analysis, including 137 males and 116 females, of median (5, 95 percentile) age 67 (47, 81) years. Of these 253 patients, 75 (29.6%) developed postpancreatectomy hepatic steatosis. Multivariable logistic regression analysis showed that female gender (p = 0.005; odds ratio: 2.387; 95% confidence interval: 1.293–4.386), body mass index > 22.5 kg/m2 (p = 0.007; odds ratio: 2.330; 95% confidence interval: 1.261–4.307), operative duration > 540 min (p = 0.018; odds ratio: 2.286; 95% confidence interval: 1.153–4.533), and delayed gastric emptying (p < 0.001; odds ratio: 4.598; 95% confidence interval: 1.979–10.678) were independent risk factors associated with postpancreatectomy hepatic steatosis. Treatment consisted of maintenance- or high-dose digestive enzyme replacement therapy. Of patients without obvious tumor recurrence after 6 months, 12 of 15 treated with high dose and only 6 of 35 treated with maintenance-dose digestive enzyme replacement therapy showed improvements in postpancreatectomy hepatic steatosis (p = 0.006).
Female gender, obesity, longer operative time, and occurrence of delayed gastric emptying are risk factors for postpancreatectomy hepatic steatosis. High-dose digestive enzyme replacement therapy may improve postpancreatectomy hepatic steatosis.
Surgical site infection, in particular superficial incision infection, is a common type of complication following abdominal surgery. Negative-pressure wound therapy has been confirmed to reduce the incidence of surgical site infection in various surgeries, but there are few prospective randomized studies into its application to abdominal surgery.
A prospective randomized controlled study was conducted in which patients with abdominal surgery and open surgery were randomly divided into a negative-pressure wound therapy experimental group and a gauze-covering control group. Information about demographic data, type of surgery, surgical sites, incision treatment outcomes, surgical site infection factors, and follow-up was recorded.
From May 2015 to December 2015, 71 patients were enrolled in this study, including 33 in the experimental group and 38 in the control group. There were 10 cases of incision complications, all superficial infections, with an incidence of 14.1%. The surgical site infection incidence was statistically different between the experimental and control groups (3.0% vs 23.7%, p = 0.031). Multivariate logistic regression analysis showed that incision length >=20 cm increased the surgical site infection incidence (odds ratio value of 15.576, p = 0.004) and that the application of negative-pressure wound therapy reduced the surgical site infection incidence (odds ratio value of 0.073, p = 0.029).
Negative-pressure wound therapy can reduce the incidence of surgical site infection in open abdominal surgery.
Peripheral artery disease in dialysis cases is more prone to critical limb ischemia compared to non-dialysis cases, with a significantly high rate of major amputation of the lower limbs. Lesions are distributed on the more distal side in dialysis critical limb ischemia cases. The aim of this study was to investigate the usefulness of indocyanine green angiography to determine differences in the regional circulation in the foot between dialysis and non-dialysis patients.
The subjects included 62 cases, among which 20 were dialysis patients and 42 were non-dialysis patients. We compared the indocyanine green angiography parameters for regions of interest in the dialysis and non-dialysis groups, which included the magnitude of intensity from indocyanine green onset to maximum intensity (Imax), the time from indocyanine green onset to maximum intensity (Tmax), the time elapsed from the fluorescence onset to half the maximum intensity (T1/2), and the time from maximum intensity to declining to 90% of the maximum intensity (Td90%). These indocyanine green angiography parameters were measured at region of interest 1 (the Chopart joint), region of interest 2 (the Lisfranc joint), and region of interest 3 (the distal region of the first metatarsal bone).
In the comparison between the dialysis and non-dialysis groups, a significant difference was observed regarding Tmax, T1/2, and Td90%, especially in region of interest 3.
In this study, we show that regional tissue perfusion is more deteriorated in dialysis patients compared with non-dialysis patients using indocyanine green angiography. Tmax, T1/2, and Td90% could be useful clinical parameters to compare ischemic severity of the lower limb between dialysis and non-dialysis patients.
Fistula-in-ano is a common problem among patients with Crohn’s disease and carries significant morbidity. We aimed to study the outcomes of surgical treatment of fistula-in-ano after fistulotomy or seton placement in patients with perianal fistulizing Crohn’s disease.
A retrospective observational study of 59 patients diagnosed with Crohn’s disease, who were treated surgically for fistula-in-ano between 2010 and 2014 in our department. The assessment of disease complexity included a detailed physical examination, magnetic resonance imaging of the rectum, and examination under anesthesia. Outcomes for analysis included wound healing rate and postoperative incontinence.
High transsphincteric fistula was found in 44% of the patients, while mid or low transsphincteric fistulas were found in 51%. Three women (5%) had a rectovaginal fistula. All patients with high transsphincteric fistulas were treated with loose seton placement. Patients with mid- or low-level transsphincteric fistula were offered either fistulotomy or seton placement based on the clinical evaluation. The mean follow-up duration was 1.6 ± 1.1 years. In terms of recurrence, one patient treated with seton placement presented with recurrence 6 months after seton removal and one patient with fistulotomy failed to achieve wound healing. Minor incontinence was found in six patients treated with fistulotomy and in three patients treated with seton placement; however, this difference was not significant (chi-square = 1.723, df = 1, Monte–Carlo: p = 0.273).
Fistulotomy could achieve good results in terms of wound healing and incontinence in strictly selected patients with Crohn’s disease suffering from low-lying transsphincteric fistulae. For more high-lying or complicated fistulae, seton placement is more appropriate. For high transsphincteric fistulae, the only option is placement of loose seton.
Flexor tendon injuries cause significant morbidity in working-age population. The epidemiology of these injuries in adult population is not well known. The aim of this study was to describe the epidemiology of flexor tendon injuries in a Northern Finnish population.
Data on flexor tendon injuries, from 2004 to 2010, were retrieved from patient records from four hospitals, which offer surgical repair of the flexor tendon injuries in a well-defined area in Northern Finland. The incidence of flexor tendon injury as well as the gender-specific incidence rates was calculated. Mechanism of injury, concomitant nerve injuries, and re-operations were also recorded.
The incidence rate of flexor tendon injury was 7.0/100,000 person-years. The incidence was higher in men and inversely related to age. The most common finger to be affected was the fifth digit. In 37% of injuries also digital nerve was affected. The most common finger to have simultaneous digital nerve injury was the thumb.
Flexor tendon laceration is a relatively rare injury. It predominantly affects working-aged young males and frequently includes a nerve injury, which requires microsurgical skills from the surgeon performing the repair. This study describes epidemiology of flexor tendon injuries and therefore helps planning the surgical and rehabilitation services needed to address this entity.
This randomized controlled trial was conducted to examine whether prophylactic active drainage decreases morbidity associated with pancreati-coduodenectomy.
A prospective, randomized controlled trial was conducted between April 2010 and May 2015 when 160 consecutive patients following elective pancreaticoduodenectomy were randomized intraoperatively to either prophylactic active drainage group or conventional passive drainage group. The main objectives were the incidence of postoperative pancreatic fistula and the associated clinical outcomes.
There were 82 patients in the active drain group and 78 patients in the passive drain group. The overall pancreatic fistula rate occurred similarly in the two groups (11.0% (9/82) vs 14.1% (11/78), p = 0.360). Grade C pancreatic fistula in active drain group was significantly less than that in passive drain group (0% (0/82) vs 6.4% (5/78), p = 0.026). The mean postoperative hospital stay and parenteral nutrition support time in active drainage group were shorter than those in passive drainage group (12.6 days vs 14.5 days, p = 0.037; 6.9 days vs 8.6 days, p = 0.047, respectively).
Prophylactic active drainage reveals significant reduction in severity of complications associated with pancreatic fistula and might be recommended as an alternative for patients with high risk of developing serious pancreatic fistula after pancreaticoduodenectomy.
The open abdomen technique is a standard procedure in the treatment of intra-abdominal catastrophe. Achieving primary abdominal closure within the initial hospitalization is a main objective. This study aimed to analyze the success of closure rate and the effect of negative pressure wound therapy, mesh-mediated medial traction, and component separation on the results. We present the treatment algorithm used in our institution in open abdomen situations based on these findings.
Open abdomen patients (n = 61) treated in Tampere University Hospital from May 2005 until October 2013 were included in the study. Patient characteristics, treatment prior to closure, closure technique, and results were retrospectively collected and analyzed. The first group included patients in whom direct or bridged fascial closure was achieved, and the second group included those in whom only the skin was closed or a free skin graft was used. Background variables and variables related to surgery were compared between groups.
Most of the open abdomen patients (72.1%) underwent fascial defect repair during the primary hospitalization, and 70.5% of them underwent direct fascial closure. Negative pressure wound therapy was used as a temporary closure method for 86.9% of the patients. Negative pressure wound therapy combined with mesh-mediated medial traction resulted in the shortest open abdomen time (p = 0.039) and the highest fascial repair rate (p = 0.000) compared to negative pressure wound therapy only or no negative pressure wound therapy. The component separation technique was used for 11 patients; direct fascial closure was achieved in 5 and fascial repair by bridging the defect with mesh was achieved in 6. A total of 8 of 37 (21.6%) patients with mesh repair had a mesh infection. The negative pressure wound therapy combined with mesh-mediated medial traction promotes definitive fascial closure with a high closure rate and a shortened open abdomen time. The component separation technique can be used to facilitate fascial repair but it does not guarantee direct fascial closure in open abdomen patients.
Reconstruction with reconstitution of the container function of the abdominal compartment is increasingly being performed in patients with massive ventral hernia previously deemed inoperable. This situation places patients at great risk of severe intra-abdominal hypertension and abdominal compartment syndrome if organ failure ensues. Intra-abdominal hypertension and especially abdominal compartment syndrome may be devastating systemic complications with systematic and progressive organ failure and death. We thus reviewed the pathophysiology and reported clinical experiences with abnormalities of intra-abdominal pressure in the context of abdominal wall reconstruction.
Bibliographic databases (1950–2015), websites, textbooks, and the bibliographies of previously recovered articles for reports or data relating to intra-abdominal pressure, intra-abdominal hypertension, and the abdominal compartment syndrome in relation to ventral, incisional, or abdominal hernia repair or abdominal wall reconstruction.
Surgeons should thus consider and carefully measure intra-abdominal pressure and its resultant effects on respiratory parameters and function during abdominal wall reconstruction. The intra-abdominal pressure post-operatively will be a result of the new intra-peritoneal volume and the abdominal wall compliance. Strategies surgeons may utilize to ameliorate intra-abdominal pressure rise after abdominal wall reconstruction including temporizing paralysis of the musculature either temporarily or semi-permanently, pre-operative progressive pneumoperitoneum, permanently removing visceral contents, or surgically releasing the musculature to increase the abdominal container volume. In patients without complicating shock and inflammation, and in whom the abdominal wall anatomy has been so functionally adapted to maximize compliance, intra-abdominal hypertension may be transient and tolerable.
Intra-abdominal hypertension/abdominal compartment syndrome in the specific setting of abdominal wall reconstruction without other complication may be considered as a quaternary situation considering the classification nomenclature of the Abdominal Compartment Society. Greater awareness of intra-abdominal pressure in abdominal wall reconstruction is required and ongoing study of these concerns is required.
Patients with acute or chronic wrist pain often undergo wrist arthroscopy for evaluation of chondral and ligamentous abnormalities. The purpose of this study was to compare findings of wrist arthroscopy with cone beam computed tomography arthrography and magnetic resonance arthrography.
Altogether, 21 patients with wrist pain underwent cone beam computed tomography arthrography, magnetic resonance arthrography, and wrist arthroscopy. Chondral surfaces of the scaphoid, lunate, and radius facing the scaphoid and lunate were evaluated. The scapholunate ligament, the lunotriquetral ligament, and the triangular fibrocartilage complex were classified as either intact or torn. Sensitivity, specificity, positive and negative predictive values, and accuracy with 95% confidence intervals were assessed.
For chondral lesions (n = 10), cone beam computed tomography arthrograms showed slightly higher specificity than magnetic resonance arthrography. The sensitivity of cone beam computed tomography arthrography was also better for these lesions, except for those on the chondral surface of the lunate. For triangular fibrocartilage complex injuries (n = 9), cone beam computed tomography arthrography showed a better specificity and sensitivity than magnetic resonance arthrography. For ligamentous injuries (n = 6), cone beam computed tomography arthrograms were more sensitive, but less specific than magnetic resonance arthrography images. However, the number of lesions was very small and the 95% confidence intervals are overlapping.
Cone beam computed tomography is an emerging imaging modality that offers several advantages over computed tomography and magnetic resonance imaging. Its usefulness particularly in ligamentous injuries should be further explored in a larger study. Cone beam computed tomography arthrography seems to offer similar sensitivity, specificity, and accuracy compared to magnetic resonance arthrography and therefore serves as a valuable option in evaluating patients with wrist pain.
Dislocation is one of the most common complications following total hip arthroplasty. The aim of our study was to assess failure rate of the Biomet Freedom constrained liner (Biomet, Warsaw, IN, USA) either in revision surgery for recurrent dislocation, or as a preventive method in high dislocation risk patients.
We assessed retrospectively 105 consecutive surgical procedures in 103 patients where a Freedom constrained liner or cup was used in Turku University Hospital over a 7-year period from 2007 to 2014. The mechanical failure rate of the device was assessed based on medical records. The average age of the patients was 73.4 years. The number of male patients was 53 (51%). Mean follow-up time was 2.5 years. The association between failure of the device and potential risk factors—age, gender, indication, and approach—was analyzed with logistic regression. Results were expressed by odd ratios and 95% confidence intervals.
The mechanical failure rate of the Freedom device was 6 out of 105 (5.7%). None of the 11 preventive primary THAs against dislocation failed, 4 out of 52 (7.7%) preventive revision THAs against dislocation failed, and 2 out of 42 (4.8%) of the treated dislocation cases failed. Four out of six failures were dislocations due to impingement and failure of the locking mechanism. Two liners failed because of loosening. The risk factors assessed were not associated with failure of the device.
We found out that the mechanical failure rate of a Freedom constrained device was low. These results encourage us to continue using the device.
Ulcerative colitis increases the risk of developing colorectal cancer. Colonoscopic surveillance is recommended although there are no randomized trials evaluating the efficacy of such a strategy. This study is an update of earlier studies from an ongoing colonoscopic surveillance program.
All patients with ulcerative colitis were invited to the surveillance program that started in 1977 at Örnsköldsvik Hospital, located in the northern part of Sweden. Five principal endoscopists performed the colonoscopies and harvested mucosal sampling for histopathological evaluation. Some 323 patients from the defined catchment area were studied from 1977 to 2014. At the end of the study period, 130 patients, including those operated on, had had total colitis for more than 10 years.
In total, 1481 colonoscopies were performed on 323 patients during the study period without any major complications. In all, 10 cases of colorectal cancer were diagnosed in 9 patients, of whom 1 died from colorectal cancer. The cumulative incidence of colorectal cancer was 1.4% at 10 years, 2.0% at 20 years, 3.0% at 30 years, and 9.4% at 40 years of disease duration, respectively. The standardized colorectal cancer incidence ratio was 3.01 (95% confidence interval: 1.42–5.91). Major surgery was performed on 65 patients; for 20 of these, the indication for surgery was dysplasia or colorectal cancer. Panproctocolectomy was performed in 43 patients.
This study supports that colonoscopic surveillance is a safe and effective long-term measure to detect dysplasia and progression to cancer. The low numbers of colorectal cancer-related deaths in our study suggest that early detection of neoplasia and adequate surgical intervention within a surveillance program may reduce colorectal cancer mortality in ulcerative colitis patients.
To evaluate the current incidence, risk factors, management, and long-term follow-up of urinary leakage following partial nephrectomy, in order to propose an algorithm for diagnosis and evaluation of postoperative urinary leakage.
The study included 752 patients who underwent elective partial nephrectomies for renal masses between the years 1988 and 2013. Patients’ demographics, clinico-pathologic variables, and operative details were collected retrospectively. The associations between urinary leakage and patients’ variables were assessed by univariate and multivariate analyses.
Of the 752 patients, 21 (2.8%) experienced urinary leakage; 4 of the 21 patients with urinary leakage had spontaneous resolution, 1 patient underwent nephrectomy, and 16 patients were treated by retrograde ureteral stents insertion. One of them necessitated insertion of an additional percutaneous nephrostomy and another one deserved concomitant percutaneous drainage of a perirenal urinoma. The average period of time that elapsed from the operation until the insertion of stent was 8.5 ± 4.5 days. Stents were removed 68 ± 20.5 days postoperatively. None of the patients had either persistent or repeated leakage. On univariate analysis, hilar renal masses (p < 0.04) and higher preoperative creatinine levels (p < 0.01) were found to be associated with higher rates of urinary leakage. None of these variables was significant on a multivariate analysis. Review of the urinary leakage rate over time revealed it has been constantly decreasing over time, from 4% in early cases to 1.3% among the most recent ones.
None of the preoperative variables that were examined in this study was significantly associated with increased risk of urinary leakage. However, cumulative surgical experience was associated with lower rates of urinary leakage, suggesting that the decrease in its incidence is related to the improved surgical skills, rather than to differences in tumors’ or patients’ characteristics.
There is a risk of decreased physical function, quality of life and persistent pain after open surgery for esophageal cancer. There are currently no studies that evaluate the effect of any postoperative intervention, including physical exercises, after this type of surgery. The aim of the study was therefore to evaluate the effect of a training intervention after Ivor-Lewis resection of the esophagus.
Patients scheduled for esophagus resection according to Ivor-Lewis were randomized to an intervention group or a control group. The training intervention started at discharge and lasted three months. Before discharge, patients were given three leaflets with exercises to increase range of motion in the affected area and exercises aiming to restore lung function and physical function. All exercises were described in detail and the patients carried out the ones in the first program under supervision. Before surgery and three months after discharge, the patients estimated their level of physical function, level of physical activity, and quality of life. They also underwent spirometry, measurements of range of motion in the rib cage, spine, and shoulders, and three functional tests. Comparisons of differences within and between the groups were made.
A total of 43 of 64 randomized patients participated in the follow-up. Postoperatively, the patients in the intervention group had a significantly higher degree of physical function and less deteriorated range of motion in right shoulder flexion and thoracic left lateral flexion. There were no significant differences between the groups in lung function, pain, or quality of life.
The results of the three-month intervention indicate that specific training can positively affect physical function and range of motion to preoperative values. The intervention was well tolerated, and no side effects were registered.
To prospectively assess the functional effect of using the extended latissimus dorsi flap in immediate breast reconstructions.
A total of 15 consecutive patients undergoing breast reconstruction with extended latissimus dorsi flap participated. Shoulder range of motion, muscle strength, lateral flexion of the torso, and position of scapula were measured pre-operatively and 1, 6, and 12 months post-operatively, in addition to donor-site post-operative complications.
At 12 months post-operatively, patients had achieved full range of shoulder movement, when compared to pre-operative values. Lateral flexion of the torso was, however, significantly reduced bilaterally at 1 and 6 months post-operatively (p = 0.001, p = 0.01) and to the not operated side at 12 months (p = 0.01). Muscle strength in flexion–extension–internal rotation was significantly (p = 0.01) reduced on the operated side 12 months post-operatively. All but one patient had numbness around the donor-site scar 12 months post-operatively, 33% had slight adhesions but all were pain free.
Although invariably, patients having extended latissimus dorsi flap may expect to achieve full range of shoulder movement, they should be informed of possible functional consequences and the time and effort it takes to recover. Further research is needed to investigate the potential long-term functional implications that extended latissimus dorsi flap may have as a result of changes in the lateral flexion of the torso and scapula position.
Esophageal perforation is a life-threatening disease. Factors impacting morbidity and mortality include the cause and site of the perforation, the time to diagnosis, and the therapeutic procedure. This study aimed to identify risk factors for morbidity and mortality after esophageal perforation.
This retrospective study analyzed data collected from all patients treated for esophageal perforation at the Department of Surgery, University of Schleswig–Holstein, Luebeck Campus, from January 1986 through December 2011.
Altogether, 80 patients (52 men, 28 women; mean age 65 years) were treated. The cause of perforation was intraluminal in 44 (55%) (group A) and extraluminal in 2 (3%) (group B). Spontaneous perforations were observed in 12 (15%) (group C). Perforations were due to a preexisting esophageal disease in 22 (28%) (group D). The survival rate was higher for group A (82%) than for groups B (50%), C (57%), and D (59%). The distal third of the esophagus had the highest prevalence of perforations (49, 61%) independent of the cause. Mortality, however, was independent of the perforation site. Perforations were diagnosed within 24 h in 57% (n = 46) of patients, associated with a statistically significant lower mortality rate (p = 0.035). Altogether, 40 patients underwent non-operative treatment, and among those 27 had endoscopic treatment. Emergency thoracic surgery was performed in 40 patients: direct suture of the defect (n = 26), partial esophageal resection (n = 11), other (n = 3). Significantly higher morbidity (p = 0.007) and prolonged hospitalization (p < 0.0001) was observed among patients who underwent emergency surgery. Mortality was higher in the surgical group (14/40) than in the non-operative treatment group (9/40) but without statistical significance.
Intraluminal perforations, rapid initiation of therapy, and non-operative treatment were associated with favorable outcomes. The perforation site did not have an impact on outcomes. Esophageal resection was associated with high mortality.
The objective of this study is to analyze outcomes of the first experiences with drug-eluting balloons in native arteries, vein grafts, and vascular accesses. The study is also a pilot for our future prospective, randomized, and controlled studies regarding the use of drug-eluting balloons in the treatment of the stenosis in bypass vein graft and dialysis access.
A total of 93 consecutive patients were retrospectively analyzed and in the end 81 were included in the study. Inclusion criteria included at least one previous percutaneous angioplasty to the same lesion. Patients were divided into three groups according to the anatomical site of the lesion: native lower limb artery, vein bypass graft, or vascular access. Time from the previous percutaneous angioplasty to the drug-eluting balloon was compared to the time from the drug-eluting balloon to endpoint in the same patient. Endpoints included any new revascularization of the target lesion, major amputation, or new vascular access.
The median time from the drug-eluting balloon to endpoint was significantly longer than the median time from the preceding percutaneous angioplasty to drug-eluting balloon in all three groups. This difference was clearest in native arteries and vein grafts, whereas the difference was smaller from the beginning and disappeared over time in the vascular access group. No significant differences were seen between the groups with regard to smoking, antiplatelet regime, diabetes, Rutherford classification, or sex.
Although the setup of this study has several limitations, the results suggest that there could be benefit from drug-eluting balloons in peripheral lesions. Very little data have been published on the use of drug-eluting balloons in vein grafts and vascular accesses, and randomized and controlled prospective studies are needed to further investigate this field.
There is a demand for a better understanding of the vascular structures around the right colonic area. Although right hemicolectomy with the recent concept of meticulous lymph node dissection is a standardized procedure for malignant diseases among most surgeons, variations in the actual anatomical vascular are not well understood. The aim of the present review was to present a detailed overview of the vascular variation pertinent to the surgery for right colon cancer.
Medical literature was searched for the articles highlighting the vascular variation relevant to the right colon cancer surgery.
Recently, there have been many detailed studies on applied surgical vascular anatomy based on cadaveric dissections, as well as radiological and intraoperative examinations to overcome misconceptions concerning the arterial supply and venous drainage to the right colon. Ileocolic artery and middle colic artery are consistently present in all patients arising from the superior mesenteric artery. Even though the ileocolic artery passes posterior to the superior mesenteric vein in most of the cases, in some cases courses anterior to the superior mesenteric artery. The right colic artery is inconsistently present ranging from 63% to 10% across different studies. Ileocolic vein and middle colic vein is always present, while the right colic vein is absent in 50% of patients. The gastrocolic trunk of Henle is present in 46%–100% patients across many studies with variation in the tributaries ranging from bipodal to tetrapodal. Commonly, it is found that the right colonic veins, including the right colic vein, middle colic vein, and superior right colic vein, share the confluence forming the gastrocolic trunk of Henle in a highly variable frequency and different forms.
Understanding the incidence and variations of the vascular anatomy of right side colon is of crucial importance. Failure to recognize the variation during surgery can result in troublesome bleeding especially during minimal invasive surgery.
Since the early 1990s, low long-term survival rates following pancreatic surgery for pancreatic ductal adenocarcinoma have challenged us to improve treatment. In this series, we aim to show improved survival from pancreatic ductal adenocarcinoma during the era of centralized pancreatic surgery.
Analysis of all pancreatic resections performed at Helsinki University Hospital and survival of pancreatic ductal adenocarcinoma patients during 2000–2013 were included. Post-operative complications such as fistulas, reoperations, and mortality rates were recorded. Patient and tumor characteristics were compared with survival data.
Of the 853 patients undergoing pancreatic surgery, 581 (68%) were pancreaticoduodenectomies, 195 (21%) distal resections, 28 (3%) total pancreatectomies, and 49 (6%) other procedures. Mortality after pancreaticoduodenectomy was 2.1%. The clinically relevant B/C fistula rate was 7% after pancreaticoduodenectomy and 13% after distal resection, and the re-operation rate was 5%. The 5- and 10-year survival rates for pancreatic ductal adenocarcinoma were 22% and 14%; for T1-2, N0 and R0 tumors, the corresponding survival rates were 49% and 31%. Carbohydrate antigen 19-9 >75 kU/L, carcinoembryonic antigen >5 µg/L, N1, lymph-node ratio >20%, R1, and lack of adjuvant therapy were independent risk factors for decreased survival.
After centralization of pancreatic surgery in southern Finland, we have managed to enable pancreatic ductal adenocarcinoma patients to survive markedly longer than in the early 1990s. Based on a 1.7-million population in our clinic, mortality rates are equal to those of other high-volume centers and long-term survival rates for pancreatic ductal adenocarcinoma have now risen to some of the highest reported.
Major upper abdominal surgery is often associated with reduced health-related quality of life and reduced survival. Patients with upper abdominal malignancies often suffer from cachexia, represented by preoperative weight loss and sarcopenia (low skeletal muscle mass) and this might affect both health-related quality of life and survival. We aimed to investigate how health-related quality of life is affected by cachexia and how health-related quality of life relates to long-term survival after major upper abdominal surgery.
From 2001 to 2006, 447 patients were included in a Norwegian multicenter randomized controlled trial in major upper abdominal surgery. In this study, six years later, these patients were analyzed as a single prospective cohort and survival data were retrieved from the National Population Registry. Cachexia was derived from patient-reported preoperative weight loss and sarcopenia as assessed from computed tomography images taken within three months preoperatively. In the original trial, self-reported health-related quality of life was assessed preoperatively at trial enrollment and eight weeks postoperatively with the health-related quality of life questionnaire Short Form 36.
A majority of the patients experienced improved mental health-related quality of life and, to a lesser extent, deteriorated physical health-related quality of life following surgery. There was a significant association between preoperative weight loss and reduced physical health-related quality of life. No association between sarcopenia and health-related quality of life was observed. Overall survival was significantly associated with physical health-related quality of life both pre- and postoperatively, and with postoperative mental health-related quality of life. The association between health-related quality of life and survival was particularly strong for postoperative physical health-related quality of life.
Postoperative physical health-related quality of life strongly correlates with overall survival after major upper abdominal surgery.
Chest-wall contouring surgery is an important part of the gender reassignment process that contributes to strengthening the self-image and facilitating living in the new gender role. Here, we analyze the surgical techniques used in our clinic and report the results.
Female-to-male transgender patients (n = 57) undergoing chest-wall contouring surgery at Tampere University Hospital between January 2003 and April 2015 were enrolled in the study. Breast appearance was evaluated and either a concentric circular approach or a transverse incision technique was used for mastectomy. Patient characteristics and data regarding the technique and postoperative results were collected and analyzed retrospectively.
In addition to the transgender diagnosis, 40.4% of the patients had another psychiatric diagnosis. For mastectomy, a concentric circular approach was used in 50.9% and a transverse incision approach in 49.1% of the patients. In the transverse incision group, 21.4% of the patients underwent pedicled mammaplasty and 78.6% mastectomy with a free nipple–areola complex graft. Compared with the transverse incision group, breasts were smaller (p < 0.001) and body mass index value was lower in the concentric circular group (p = 0.001). One-third of the patients had complications (hematoma, infection, seroma, fistula, or partial necrosis of nipple–areola complex) and the reoperation rate was 8.8%. Hematoma was the most frequent reason for reoperation. Corrections were required for the scar in 14.0% of the patients, the contour in 28.0%, the areola in 15.8%, and the nipple in 5.3%. Secondary corrections were needed more often in the concentric circular (55.2%) than in the transverse incision group (25.0%; p = 0.031).
The larger the breast, poorer the skin quality, and greater the amount of excess skin, the longer the required incision and resulting scar is for mastectomy of female-to-male patients. Hematoma is the most common reason for acute reoperation and secondary corrections are often needed.
Development of a pouch-related fistula tract is an uncommon but highly morbid complication to restorative proctocolectomy with ileal pouch-anal anastomosis. Pouch failure with permanent ileostomy is reported in 21%–30% of patients, yet the factors contributing to pouch excision remain poorly defined. The aim of this study was to determine the incidence and treatment results of complicated pouch-related fistula, as well as to evaluate factors involved in excision after pouch failure.
The study was conducted as a retrospective study. All patients with diagnosed pouch-related fistulas were registered with information related to fistula classification, treatments, and outcome.
The final analysis included 48 (10.7%) of the 447 total ileal pouch-anal anastomosis patients with complicated pouch-related fistulas. Pouch-vaginal fistulas, pouch-perianal fistulas, and other pouch-related fistulas were observed in 19 (63%), 29 (60%), and 10 (21%) patients, respectively, corresponding to an accumulated risk of 8%, 6%, and 2%, respectively. Time from ileal pouch-anal anastomosis surgery to fistula presentation was 24 (0.2–212) months. Overall pouch failure, defined as pouch excision or a diverting stoma, was seen in 34 (71%) patients, while pouch excision was seen in 23 (48%) of the patients. Patients who developed Crohn’s disease had a significantly higher risk of pouch excision, as did patients with an early onset of the fistula after ileal pouch-anal anastomosis (P = 0.006 and P = 0.007, respectively). In conclusion, the present study demonstrated a high risk of pouch failure in patients with complicated pouch-related fistulas. Furthermore, it showed that Crohn’s disease and the development of early onset fistulas are associated with pouch excision.
Skeletonization has been proposed as a technique to minimize the risk of sternal devascularization during bilateral internal thoracic artery harvest for coronary artery bypass grafting. The impact of this strategy on late radiologic pleuropulmonary changes has not been addressed.
Post-operative chest radiographs from patients (n = 253 per group) undergoing bilateral internal thoracic artery harvest using skeletonized and non-skeletonized techniques were reviewed by blinded radiologists. The primary outcome was the incidence of atelectasis and pleural effusion. Multivariable linear regression models were derived to assess the relationship of radiologic pleuropulmonary outcomes to patients and operative variables.
Patients in the skeletonized group were older (p < 0.0001), had a lower preoperative hematocrit (p = 0.014), had higher prevalence of peripheral vascular disease (p = 0.001), were of female gender (p = 0.015), underwent off-pump surgery (p < 0.001), had urgent/emergent status (p = 0.024), and had chronic obstructive pulmonary disease (p = 0.019). There was no difference in the incidence of post-operative complications, ventilation time, or intensive care unit stay. There was no difference in the severity of post-operative atelectasis in both groups. More patients in the non-skeletonized group had a grade 2/3 left pleural effusion on the late post-operative chest X-ray (p = 0.007). The independent effect of skeletonization on the development of a late left pleural effusion was significant (odds ratio = 0.558, 95% confidence interval = 0.359–0.866, p = 0.009). Skeletonization results in a decreased incidence of late post-operative left pleural effusion with no difference in early or late atelectasis. Further studies are warranted to assess the mechanism of these pleuropulmonary changes and the impact of other factors such as pleural violation during surgery.
Patient-rated outcome measures have become increasingly important in clinical research. They provide research and clinical tools which can be utilized in the assessment of patient recovery and treatment efficacy. The purpose of our study was to translate and validate the original version of the PRWE form into Finnish.
We conducted the translation of the PRWE questionnaire according to standardized guidelines. Patients (N = 119) with an acute distal radius fracture were recruited, and they completed the PRWE and QuickDASH questionnaires at 2 months and 4 months after the wrist injury.
The mean answering times were 52 days (standard deviation [SD] 9.8 days) and 116 days (standard deviation [SD] 14.8 days), respectively. Both the internal consistency (Cronbach’s alpha) of 0.976 and the intraclass correlation coefficient (ICC) of 0.992 (95% CI 0.966–0.998) showed excellent reliability for the total PRWE score. The correlation coefficients between the total score, the subscales, and for improvement over time for PRWE and QuickDASH were excellent. The responsiveness was good with an effect size of 0.83 and a standard response mean of 1.22.
Our study shows that the Finnish version of the PRWE is reliable, valid, and responsive for the evaluation of pain and disability after distal radius fracture.
The increase in liver surgery and the proportion of resections done on the margin to postoperative liver failure make preoperative calculations regarding liver volume important. Earlier studies have shown good correlation between calculations done with ImageJ and specimen weight as well as volume calculations done with more robust systems. The correlation to actual volumes of resected liver tissue has not been investigated, and this was the aim of this study.
A total of 30 patients undergoing well-defined liver resections were included in this study. Volumes calculated with ImageJ were compared to volume measurements done after the retrieval of resected liver tissue.
A strong correlation between calculated and measured liver volume was found with sample concordance correlation coefficient (c) = 0.9950. The knowledge on the nature of liver resections sets liver surgeons in a unique position to be able to accurately predict the volumes to be resected and, therefore, also the volume that will remain after surgery. This becomes increasingly important with the evolvement of methods to extend the boundaries of liver surgery. ImageJ is a reliable tool to preoperatively assess liver volume.
Diagnostic performance of patellar position for patellar cartilage lesions remains unclear. The aim of this study was to assess the abnormal patella height and its correlation with chondral lesions of the patellofemoral joint in China.
A total of 1703 consecutive patients who performed knee joint examination using an extremity-dedicated low-field magnetic resonance imaging were enrolled in this study. Patellar cartilage lesions were diagnosed based on the result of magnetic resonance imaging and clinical data. Patella height was defined as the ratio of patellar tendon length to patellar length according to Insall-Salvati index. Patella alta and infera were defined as tendon length/patellar length >1.2 and <0.8, respectively.
The total prevalence of patellar cartilage lesions was 38.0%. The prevalence in females was significantly higher than that in males (46.4% vs 28.8%, p < 0.001). Age notably increased the incidence of patellar cartilage lesions (p < 0.001). Logistic regression analysis showed that tendon length/patellar length ratio was significantly correlated with patellar cartilage lesions (odds ratio = 6.380, p < 0.001). Furthermore, patients with cartilage lesions showed significantly higher rates of patella alta and infera (p < 0.001). In addition, receiver operating characteristic curve analysis demonstrated that abnormal patella height had statistical significance in diagnosing cartilage lesions (p < 0.001). However, the area under the curve (0.596; 95% confidence interval: 0.568–0.624) and sensitivity (47.0%) were relatively low, while the specificity was 72.2%.
Patients with patellar cartilage lesions have an increased tendon length/patellar length ratio. The abnormal patella height is significantly correlated with chondral lesions and can be used as a potential diagnostic marker.
Alpine skiing and snowboarding share the hazards of accidents accounting for tibial fractures. The aim of this study was to evaluate the fracture patterns and mechanisms of injury of tibial fractures taking place in downhill skiing and snowboarding.
All patients with tibial fracture due to alpine skiing or snowboarding accident treated in four trauma centers next to the largest ski resorts in Finland were analyzed between 2006 and 2012. The hospital records were retrospectively reviewed for data collection: equipment used (skis or snowboard), age, gender, and mechanism of injury. Fractures were classified according to AO-classification.
There were 342 skiing and 30 snowboarding related tibial fractures in 363 patients. Tibial shaft fracture was the most common fracture among skiers (n = 215, 63%), followed by proximal tibial fractures (n = 92, 27%). Snowboarders were most likely to suffer from proximal tibial fracture (13, 43%) or tibial shaft fracture (11, 37%). Snowboarders were also more likely than skiers to suffer complex AO type C fractures (23% vs 9%, p < 0.05). Adult skiers had both wider variety of fractures and higher prevalence of proximal tibial fractures compared to children (49% vs 16%, p < 0.05). Skiers typically got injured due to falling down on the same level (70%) and snowboarders due to loss of control while jumping (46%).
The most important finding was the relatively high number of the tibial plateau fractures among adult skiers. The fracture patterns between snowboarding and skiing were different; the most common fracture type in skiers was spiral tibial shaft fracture compared to proximal tibial fractures in snowboarders. Children had more simple fractures than adults.
The laparoscopic approach has been increasingly used to treat adhesive small-bowel obstruction. The aim of this study was to compare the outcomes of a laparoscopic versus an open approach for adhesive small-bowel obstruction.
Data were retrospectively collected on patients who had surgery for adhesive small-bowel obstruction at a single academic center between January 2010 and December 2012. Patients with a contraindication for the laparoscopic approach were excluded. A propensity score was used to match patients in the laparoscopic and open surgery groups based on their preoperative parameters.
A total of 25 patients underwent laparoscopic adhesiolysis and 67 patients open adhesiolysis. The open adhesiolysis group had more suspected bowel strangulations and more previous abdominal surgeries than the laparoscopic adhesiolysis group. Severe complication rate (Clavien–Dindo 3 or higher) was 0% in the laparoscopic adhesiolysis group versus 14% in the open adhesiolysis group (p = 0.052). Twenty-five propensity score–matched patients from the open adhesiolysis group were similar to laparoscopic adhesiolysis group patients with regard to their preoperative parameters. Length of hospital stay was shorter in the laparoscopic adhesiolysis group compared to the propensity score–matched open adhesiolysis group (6.0 vs 10.0 days, p = 0.037), but no differences were found in severe complications between the laparoscopic adhesiolysis and propensity score–matched open adhesiolysis groups (0% vs 4%, p = 0.31).
Patients selected to be operated by the open approach had higher preoperative morbidity than the ones selected for the laparoscopic approach. After matching for this disparity, the laparoscopic approach was associated with a shorter length of hospital stay without differences in complications. The laparoscopic approach may be a preferable approach in selected patients.
We present our endoscopic technique for treating ejaculatory duct and seminal vesicle diseases with a holmium laser.
Fifteen patients with persistent hematospermia were enrolled in this study from June 2007 to April 2014. All patients had failed medical treatments. All patients were evaluated with transrectal ultrasound and pelvic computed tomography or magnetic resonance imaging. We performed endoscopic treatment with a semi-rigid ureteroscope after dilation using a guidewire and ureteral serial dilator. A holmium laser was used to incise the obstructed ejaculatory duct, coagulate hemorrhagic mucosa, and fragment stones in the ejaculatory duct or seminal vesicles. Stones were removed using a basket and forceps.
The mean duration of hematospermia was 30.6 months. Mean patient age was 45.3 years. The mean serum levels of prostate-specific antigen and testosterone were 1.36 and 4.95 ng/mL, respectively. No operative complications were encountered. Mean operative time was 35.4 min. Seven patients had ejaculatory duct or seminal vesicle stones, which were subsequently determined to be carbonate apatite, mucin, struvite, and calcium oxalate dehydrate stones. Mean duration of follow-up was 32.1 months. Although two patients showed recurrent hematospermia 11 and 12 months after the operation, hematospermia resolved in 13 patients (86.7%). The infertile patient showed an improved semen finding and had a successful pregnancy.
Endoscopic treatment using a holmium laser is minimally invasive and was effective for treating ejaculatory duct and seminal vesicle diseases, which are the main cause of hematospermia.
Cardiopulmonary bypass induces a systematic inflammatory response, which is partly understood by investigation of peripheral blood cytokine levels alone; the lungs may interfere with the net cytokine concentration. We investigated whether lung ventilation influences lung passage of some cytokines after coronary artery bypass grafting.
In total, 47 patients undergoing coronary artery bypass grafting were enrolled, and 37 were randomized according to the ventilation technique: (1) No-ventilation group, with intubation tube detached from the ventilator; (2) low tidal volume group, with continuous low tidal volume ventilation; and (3) continuous 10 cm H2O positive airway pressure. Ten selected patients undergoing surgery without cardiopulmonary bypass served as a referral group. Representative pulmonary and radial artery blood samples were collected for the evaluation of calculated lung passage (pulmonary/radial artery) of the pro-inflammatory cytokines (interleukin 6 and interleukin 8) and the anti-inflammatory interleukin 10 immediately after induction of anesthesia (T1), 1 h after restoring ventilation/return of flow in all grafts (T2), and 20 h after restoring ventilation/return of flow in all grafts (T3).
Pulmonary/radial artery interleukin 6 and pulmonary/radial artery interleukin 8 ratios (p = 0.001 and p = 0.05, respectively) decreased, while pulmonary/radial artery interleukin 10 ratio (p = 0.001) increased in patients without cardiopulmonary bypass as compared with patients with cardiopulmonary bypass.
The pulmonary/radial artery equation is an innovative means for the evaluation of cytokine lung passage after coronary artery bypass grafting. The mode of lung ventilation has no impact on some cytokines after coronary artery bypass grafting in patients treated with cardiopulmonary bypass.
The principle of complete mesocolic excision for colon cancer has been introduced to improve oncologic outcome. However, this approach is scantily discussed for laparoscopic surgery and there is a lack of randomized trials. This study examined oncologic and clinical outcome after laparoscopic wide mesocolic excision and central vascular ligation for colon cancer.
This is a review of prospectively gathered data from a single-institution colorectal cancer database. This study was conducted in the Central Hospital of Central Finland. From January 2003 to December 2011, 222 patients underwent laparoscopic colonic resections with wide mesocolic excision and central vascular ligation in the multimodal setting. The main measures of outcome were cancer recurrence and survival, with early recovery, 30d-mortality and morbidity, reoperation, readmission, and late complications as secondary outcomes.
The median follow-up was 5.5 (interquartile range (IQR) = 3.7–8.0) years. The 5-year overall survival for all 222 patients was 80.2% and disease-specific survival was 87.5%, and for those 210 R0-patients with stage I–III disease, 83.9% and 91.3%, respectively. The 5-year disease-free survival was 85.8%: stage I was 94.7%, stage II was 90.8%, and stage III was 75.6% (p = 0.004). Increasing lymph node ratio significantly decreased the 5-year disease-free survival. Conversion rate to open surgery was 12.2%. Thirty-day mortality was 1.3% and morbidity, 19.7%. Median postoperative hospital stay was 5 (IQR = 3–7) days.
Laparoscopic wide mesocolic excision and central vascular ligation for colon cancer resulted in good long-term oncologic outcome. Randomized trials are needed to show that laparoscopic complete mesocolic excision technique would become the standard of care for the carcinoma of the colon.
Despite retrospective data indicating short-term superiority for laparoscopic distal pancreatectomy compared to open distal pancreatectomy, the implementation of the procedure has been slow. The aim of this study was to investigate whether patients operated with laparoscopic distal pancreatectomy during the early phase of introduction are at higher risk for complications than patients operated with open distal pancreatectomy.
A retrospective single-center analysis of patients operated with laparoscopic distal pancreatectomy (n = 37) from the introduction of the procedure and comparison regarding demographic data, preoperative data, operative factors, and postoperative outcomes to patients operated with open distal pancreatectomy was done.
Operation duration shortened (195 vs 143 min, p = 0.04) and severe complications reduced (37% vs 6%, p = 0.02) significantly in the laparoscopic distal pancreatectomy group between the first half of the study and the second half. Blood loss was significantly (p < 0.001) lower in the laparoscopic distal pancreatectomy group (75 mL) than in the open distal pancreatectomy group (550 mL), while complication rate and hospital stay as well as the percentage of radical resections were the same.
Laparoscopic distal pancreatectomy can be introduced without jeopardizing patient safety and well-being during the early learning curve. The procedures should be compared in a prospective randomized manner.
Associating liver partition and portal vein ligation for staged hepatectomy may increase the possibility of radical resection in the case of liver malignancy. Concerns have been raised about the high morbidity and mortality associated with the procedure, particularly when applied for diagnoses other than colorectal liver metastases. The aim of this study was to analyze the initial experience with associating liver partition and portal vein ligation for staged hepatectomy in cases of non-colorectal liver metastases and primary hepatobiliary malignancies in Scandinavia.
A retrospective analysis of all associating liver partition and portal vein ligation for staged hepatectomy procedures performed at two Swedish university hospitals for non-colorectal liver metastases and primary hepatobiliary malignancies was performed. The primary focus was on the safety of the procedure.
Ten patients were included: four had hepatocellular cancer, three had intrahepatic cholangiocarcinoma, one had a Klatskin tumor, one had ocular melanoma metastasis, and one had a metastasis from a Wilms’ tumor. All patients completed both operations, and the highest grade of complication (according to the Clavien-Dindo classification) was 3A, which was observed in one patient. No 90-day mortality was observed. Radical resection (R0) was achieved in nine patients, while the resection was R2 in one patient. The low morbidity and mortality observed in this cohort compared with those of earlier reports on associating liver partition and portal vein ligation for staged hepatectomy for diagnoses other than colorectal liver metastases may be related to the selection of patients with limited comorbidity. In addition, procedures other than associating liver partition and portal vein ligation for staged hepatectomy had been avoided in most of the patients. In conclusion, associating liver partition and portal vein ligation for staged hepatectomy can be applied to primary hepatobiliary malignancies and non-colorectal liver metastases with acceptable rates of morbidity and mortality.
The aim of the present study was to determine whether usage of mesh with larger pores, compared with mesh with smaller pores, would result in a decreased rate of chronic pain at 3-year follow-up. According to earlier published short-term results, differences in mesh pore size do not influence the rate of chronic pain.
The patients were randomized into two study groups for which meshes with similar weight but different pore size were used: the UM group received Ultrapro mesh (pore size 3–4 mm) and the OM group received Optilene LP mesh (pore size 1 mm). Pain scores were measured on a visual analog scale. The feeling of a foreign body was a yes-or-no question.
A total of 65 patients in the UM group and 63 patients in the OM group were included in analysis. Of the patients, 33.9% in the UM group and 15.9% in the OM group reported having experienced pain during different activities at 3-year follow-up (P = 0.025). Comparison with the results of 6-month follow-up (46.3% in the UM group, 34.3% in the OM group) showed that the rate of chronic pain had decreased significantly in the OM group (P = 0.009) but not in the UM group (P = 0.113). The feeling of a foreign body in the inguinal region was experienced by 23.1% of the patients in the UM group and by 15.9% in the OM group (P = 0.375). There was one hernia recurrence in the OM group. Severe preoperative pain and younger age were identified as risk factors for development of chronic pain.
Mesh with larger pores, compared with mesh with smaller pores, has no advantages in reducing the rate of chronic pain. We speculate that the reason for the higher rate of chronic pain in the study group where the mesh with larger pores was used might have been the different composition of the meshes at implantation. Also, it is possible as development of chronic pain after inguinal hernia repair is multifactorial, we failed to find a plausible explanation for this difference. Low recurrence rates were achieved with both meshes used in our study.
Burn anemia represents a common complication following a burn injury. Burn anemia etiology carries distinct features occurring at each stage of the post-injury and treatment periods resulting from different causes. We aimed to analyze the use of blood components in Finnish burn victims and to identify patient- and injury-related factors influencing their use.
To study the use of blood products in burn patients, we used data collected from the Optimal Use of Blood registry, developed through co-operation between 10 major hospital districts and the Finnish Red Cross Blood Service. Burn patients >=18 years treated at the Helsinki University Hospital between 2005 and 2011 with an in-hospital stay >=1 day who received at least one transfusion during their hospital stay were included in this study.
Among all 558 burn patients, 192 (34%) received blood products during their hospital stay. The transfused cohort comprised 192 burn patients. The study cohort received a total of 6087 units of blood components, 2422 units of leukoreduced red blood cells, 1728 units of leukoreduced platelets, and 420 units of single-donor fresh frozen plasma or, after 2007, 1517 units of Octaplas® frozen plasma. All three types of blood components were administered to 29% of patients, whereas 45% received only red blood cells and 6% received only Octaplas. Transfused patients were significantly older (p < 0.001), experienced fire-/flame-related accidents and burns to multiple locations (p < 0.001), and their in-hospital mortality exceeded that for non-transfused burn patients fivefold (p < 0.05).
We show that Finnish adult burn patients received ample transfusions. The number of blood components transfused varied according to the anatomical location of the injury and patient survival. Whether the additional mortality is related directly to transfusions or is merely a manifestation of the more severe burn injury remains unknown.
Multivisceral resection for advanced tumors can result in prolonged survival but may also increase the risk of postoperative morbidity and mortality. The primary aim of this study was to investigate whether extensive resections increase the severity of postoperative complications.
A retrospective study was conducted between 2009 and 2014 at the Linköping University Hospital surgical department. All patients with a confirmed or presumed malignant disease who underwent a non-standardized surgical procedure requiring a multivisceral resection were included. The primary endpoint was 90-day complications according to the Clavien-Dindo score.
Forty-eight patients were included, with an age range of 17–77 years. A median of three organs was resected. The most common diagnoses were neuroendocrine tumor (n = 8), gastric cancer (n = 7), and gastrointestinal stromal tumor (n = 6). One patient died during surgery. Complications >= grade 3b according to Clavien-Dindo score occurred in 10 patients. R0 resection was achieved in 32 patients. No correlation was observed between the number of anastomoses, perioperative blood loss, operative time, and complications. Only postoperative blood transfusion was correlated with severe complications (p = 0.046); however, a tendency toward more complications with an increasing number of resected organs was observed (p = 0.06).
Multivisceral resection can result in R0, potentially curing patients with advanced tumors. Here, no correlation between extensive resections and complications was observed. Only postoperative blood transfusion was correlated with severe complications.
Intracranial complications of paranasal sinusitis have become rare due to widespread and early use of antibiotics. Potentially life-threatening intracranial complications of sinusitis include subdural empyema, epidural and intracerebral abscess, meningitis, and sinus thrombosis. Patients with intracranial complication of sinusitis can present without neurological signs, which may delay diagnosis and correct treatment.
Our aim was to evaluate the diagnostics, treatment, and outcome of sinusitis-related intracranial infections at our tertiary referral hospital with a catchment area of 1.9 million people.
We retrospectively collected data on all patients diagnosed and treated with an intracranial infection at the Helsinki University Hospital, Helsinki, Finland, during a 10-year period between 2003 and 2013.
Six patients were diagnosed to have a sinusitis-related intracranial infection. Four patients had an epidural abscess, one both an epidural abscess and a subdural empyema and one a subdural empyema. The most common presenting complaint was headache (100%) followed by fever (83%), vomiting (50%), nasal congestion (50%), forehead lump (34%), and neck stiffness (17%). All patients were managed surgically. Most (83%) patients recovered to premorbid state without neurological sequelae. One patient died intraoperatively.
Patients with a sinusitis-related intracranial suppuration typically present with signs of raised intracranial pressure rather than signs of sinusitis. Most are likely to need neurosurgical intervention and evacuation of the abscess without delay.
Proximal humerus fractures are common fragility injuries. The incidence of these fractures has been estimated to be 82–105 per 105 person-years. Treatment of this fracture, especially in the elderly, is controversial. Our study group published a systematic review of the available literature and concluded that non-operative methods are favored over operative methods in three- and four-part fractures. The aim of this multinational study was to compare treatment policies for proximal humerus fractures among the Nordic countries and Estonia.
The study was conducted as a questionnaire-based survey, using the Internet-based program, Webropol® (webropol.com). The questionnaire link was sent to the surgeons responsible for treating proximal humerus fractures in major public hospitals in Estonia, Finland, Norway, and Sweden. Questionnaire included questions regarding the responder’s hospital, patient characteristics, and examinations taken before decision making. Clinical part included eight example patient cases with treatment options.
Of the 77 recipients of the questionnaire, 59 responded; consequently, the response rate was 77%. Based on the eight presented displaced fracture examples, in both Estonia and Norway and in Finland, 41% and 38%, respectively, preferred surgical treatment with locking plate. In Sweden, the percentage was 28%. The pre- and post-operative protocols showed a similarity in all participant countries.
Our survey revealed a remarkable uniformity in the current practice of operative treatments and rehabilitation for proximal humerus fractures in the participant countries.
According to the heterogeneous results of previous studies, the prevalence of abdominal aortic aneurysm seems high among men with coronary artery disease. The associating risk factors for abdominal aortic aneurysm in this population require clarification. Our objective was to assess the prevalence of non-diagnosed abdominal aortic aneurysms in men with angiographically verified coronary artery disease and to document the associated co-morbidities and risk factors.
Altogether, 407 men with coronary artery disease were screened after invasive coronary angiography in two series at independent centers. Risk factor data were recorded and analyzed.
The mean age of the study cohort was 70.0 years (standard deviation: 11.0). The prevalence of previously undiagnosed abdominal aortic aneurysms in the whole screened population of 407 men was 6.1% (n = 25/407). In a multivariate analysis of the whole study population, the only significant risk factors for abdominal aortic aneurysm were age (odds ratio: 1.04, 95% confidence interval: 1.00–1.09) and history of smoking (odds ratio: 3.13, 95% confidence interval: 1.26–7.80). Non-smokers with abdominal aortic aneurysm were significantly older than smokers (mean age: 80.7 (standard deviation: 8.0) vs 68.0 (standard deviation: 11.1), p = 0.003), and age was a significant risk factor only among non-smokers (p = 0.011; p = 0.018 for interaction). Among smokers, the prevalence of abdominal aortic aneurysm was 8.8%, and 72% (n = 18/25) of all diagnosed abdominal aortic aneurysm patients were smokers. Prevalence of undiagnosed abdominal aortic aneurysms among patients with coronary artery disease is high, and history of smoking is the most significant risk factor for abdominal aortic aneurysm. Effectiveness of selective screening of abdominal aortic aneurysm in male patients with coronary artery disease warrants further studies.
Bioactive glass S53P4 is an antibacterial bone substitute with bone-bonding and osteostimulative properties. The bone substitute has been successfully used clinically in spine; trauma; orthopedic; ear, nose, and throat; and cranio-maxillofacial surgeries. Bioactive glass S53P4 significantly reduces the amount of bacteria in vitro and possesses the capacity to kill both planktonic bacteria and bacteria in biofilm. Three patients with severe spondylodiscitis caused by Mycobacterium tuberculosis, Candida tropicalis, or Staphylococcus aureus were operatively treated due to failed conservative treatment. The vertebral defects were reconstructed using bioactive glass S53P4 and an expandable replacement device.
Decompression and a posterolateral spondylodesis, using transpedicular fixation, were performed posteriorly in combination with an anterior decompression and reconstruction using an expandable vertebral body replacement device. For patients 1 and 2, the expander was covered with bioactive glass S53P4 only, and for patient 3, the glass was mixed with autograft bone.
The patients healed well with complete neurological recovery. Fusion was observed for all patients. The total follow-up was 4 years for patient 1, 1 year and 8 months for patient 2, and 2 years and 2 months for patient 3. No relapses or complications were observed.
The antibacterial properties of bioactive glass S53P4 also make it a suitable bone substitute in the treatment of severe spondylodiscitis.
Injuries are often missed during the primary and secondary surveys in trauma patients. Studies have suggested that a formal tertiary survey protocol lowers the number of missed injuries. Our aim was to determine the number, severity, and consequences of injuries missed by a non-formalized trauma tertiary survey, but detected within 3 months from the date of injury in trauma patients admitted to a trauma intensive care unit.
We conducted a cohort study of trauma patients admitted to a trauma intensive care unit between 1 January and 17 October 2013. We reviewed the electronic medical records of patients admitted to the trauma intensive care unit in order to register any missed injuries, their delay, and possible consequences. We classified injuries into four types: Type 0, injury detected prior to trauma tertiary survey; Type I, injury detected by trauma tertiary survey; Type II, injury missed by trauma tertiary survey but detected prior to discharge; and Type III, injury missed by trauma tertiary survey and detected after discharge.
During the study period, we identified a total of 841 injuries in 115 patients. Of these injuries, 93% were Type 0 injuries, 3.9% were Type I injuries, 2.6% were Type II injuries, and 0,1% were Type III injuries. Although most of the missed injuries in trauma tertiary survey (Type II) were fractures (50%), only 2 of the 22 Type II injuries required surgical intervention. Type II injuries presumably did not cause extended length of stay in the intensive care unit or in hospital and/or morbidity.
In conclusion, the missed injury rate in trauma patients admitted to trauma intensive care unit after trauma tertiary survey was very low in our system without formal trauma tertiary survey protocol. These missed injuries did not lead to prolonged hospital or trauma intensive care unit stay and did not contribute to mortality. Most of the missed injuries received non-surgical treatment.
There is an increasing trend toward performing liver resections in the setting of metastatic disease. Renal cell cancer liver metastases are associated with poor survival. The indications for and the short- and long-term outcomes of liver resection for renal cell cancer liver metastases remain not well defined.
A focused, structured literature review on PubMed, EMBASE, and Google Scholar was performed to identify primary research articles, on short- and long-term outcomes and prognostic factors of patients undergoing liver resection for renal cell cancer liver metastases. Only studies with a sample size equal or larger than 10 patients were included.
A total of 10 studies met inclusion criteria. Median overall survival ranged between 16 and 142 months. Major morbidity was rare while 30-day postoperative mortality was less than 5%. A disease-free interval of more than 2 years from nephrectomy to evidence of liver metastases and a radical, microscopically negative surgical resection (R0) were the most consistent prognostic factors that, in turn, could be used as potential selection criteria to identify patients who can benefit the most from liver-directed surgery. Liver surgery for renal cell cancer liver metastases can be performed with low mortality, acceptable morbidity, and promising survival benefit in carefully selected patients. Studies that can assess the impact of modern, targeted regimens in the preoperative setting and liver-directed surgery and in turn shape new selection criteria are warranted.
One by one, minimally invasive alternatives to established gastrointestinal procedures have become clinical routine. We have studied the use of laparoscopy in four common procedures—cholecystectomy, appendectomy, reflux surgery, and bariatric surgery—as well as in major resectional gastrointestinal surgery in Sweden.
The National Patient Registry was used to identify all in-hospital procedures performed in patients above the age of 15 during 1998–2014, meeting our inclusion criteria. For each group, the annual number of procedures and proportion of laparoscopic surgery were studied, as well as applicable subgroups. Differences in age, gender, as well as geographical differences were evaluated in the most recent 3-year period (2012–2014).
In total, 537,817 procedures were studied, 43% by laparoscopic approach. In 2012–2014, the proportion of laparoscopic surgery ranged from high rates in the four common procedures (cholecystectomy 81%, appendectomy 47%, reflux surgery 72%, and bariatric surgery 97%) to rather low numbers in resectional surgery (4%–10%), however, increasing in the last years. In appendectomy and cholecystectomy, men were less likely to have laparoscopic surgery (42% versus 51% and 74% versus 85%, respectively, p < 0.001). Substantial geographical differences in the use of laparoscopy were also noted, for example, the proportion of laparoscopic appendectomy varied from 11% to 76% among the 21 different Swedish counties.
The proportion of laparoscopy was high in the four common procedures and low, but rising, in major resectional surgery. A large variation in the proportion of laparoscopic surgery by age, gender, and place of residence was noted.
Intraoperative testing of gastrointestinal anastomosis effectively ensures anastomotic integrity. This study investigated whether the routine use of methylene blue intraoperatively identified leaks to reduce the postoperative proportion of clinical leaks.
This study retrospectively analyzed consecutive total gastrectomies performed from January 2007 to December 2014 in a university hospital setting by a general surgical group that exclusively used the methylene blue test. All surgeries were performed for gastric or junctional cancers (n = 198). All reconstructions (Roux-en Y esophagojejunostomy) were performed using a stapler. The methylene blue test was used in 108 cases (group 1) via a nasojejunal tube. No test was performed for the other 90 cases (group 2). Intraoperative leakage rate, postoperative clinical leakage rate, length of hospitalization, and mortality rate were the outcome measures.
The intraoperative leakage rate was 7.4% in group 1. The postoperative clinical leakage rate was 8.6%. The postoperative clinical leakage rate was 3.7% in group 1 and 14.4% in group 2 (p = 0.007). There were no postoperative clinical leaks when an intraoperative leak led to concomitant intraoperative repair. The median length of hospital stay was 6 days in group 1 and 8 days in group 2 (p < 0.001). One death occurred in each group. No test-related complications were observed.
The methylene blue test for esophagojejunostomy is a safe and reliable method for the assessment of anastomosis integrity, especially in cases with difficult esophagojejunostomic construction.
We compared laparoscopic and robotic gastrectomies with open gastrectomies and with each other that were held for gastric cancer in Europe.
We searched for studies conducted in Europe and published up to 20 February 2015 in the PubMed database that compared laparoscopic or robotic with open gastrectomies for gastric cancer and with each other.
We found 18 original studies (laparoscopic vs open: 13; robotic vs open: 3; laparoscopic vs robotic: 2). Of these, 17 were non-randomized trials and only 1 was a randomized controlled trial. Only four studies had more than 50 patients in each arm. No significant differences were detected between minimally invasive and open approaches regarding the number of retrieved lymph nodes, anastomotic leakage, duodenal stump leakage, anastomotic stenosis, postoperative bleeding, reoperation rates, and intraoperative/postoperative mortality. Nevertheless, laparoscopic procedures provided higher overall morbidity rates when compared with open ones, but robotic approaches did not differ from open ones. On the contrary, blood loss was less and hospital stay was shorter in minimally invasive than in open approaches. However, the results were controversial concerning the duration of operations when comparing minimally invasive with open gastrectomies. Additionally, laparoscopic and robotic procedures provided equivalent results regarding resection margins, duodenal stump leakage, postoperative bleeding, intraoperative/postoperative mortality, and length of hospital stay. On the contrary, robotic operations had less blood loss, but lasted longer than laparoscopic ones. Finally, there were relatively low conversion rates in laparoscopic (0%–6.7%) and robotic gastrectomies (0%–5.6%) in most studies.
Laparoscopic and robotic gastrectomies may be considered alternative approaches to open gastrectomies for treating gastric cancer. Minimally invasive operations are characterized by less blood loss and shorter hospital stay than open ones. In addition, robotic procedures have less blood loss, but last longer than laparoscopic ones.
Sentinel node biopsy is a standard method for nodal staging in patients with clinically localized cutaneous melanoma, but the survival advantage of sentinel node biopsy remains unsolved. The aim of this case–control study was to investigate the survival benefit of sentinel node biopsy.
A total of 305 prospective melanoma patients undergoing sentinel node biopsy were compared with 616 retrospective control patients with clinically localized melanoma whom have not undergone sentinel node biopsy. Survival differences were calculated with the median follow-up time of 71 months in sentinel node biopsy patients and 74 months in control patients. Analyses were calculated overall and separately in males and females.
Overall, there were no differences in relapse-free survival or cancer-specific survival between sentinel node biopsy patients and control patients. Male sentinel node biopsy patients had significantly higher relapse-free survival (P = 0.021) and cancer-specific survival (P = 0.024) than control patients. In females, no differences were found. Cancer-specific survival rates at 5 years were 87.8% in sentinel node biopsy patients and 85.2% in controls overall with 88.3% in male sentinel node biopsy patients and 80.6% in male controls and 87.3% in female sentinel node biopsy patients and 89.8% in female controls.
Sentinel node biopsy did not improve survival in melanoma patients overall. While females had no differences in survival, males had significantly improved relapse-free survival and cancer-specific survival following sentinel node biopsy.
Hemorrhage is a rare but dreaded complication after pancreatic surgery. The aim of this study was to examine the incidence, risk factors, management, and outcome of postpancreatectomy hemorrhage in a tertiary care center.
A retrospective observational study was conducted on 500 consecutive patients undergoing major pancreatic resections at our institution. Postpancreatectomy hemorrhage was defined according to the International Study Group of Pancreatic Surgery criteria.
A total of 68 patients (13.6%) developed postpancreatectomy hemorrhage. Thirty-four patients (6.8%) had a type A, 15 patients (3.0%) had a type B, and the remaining 19 patients (3.8%) had a type C bleed. Postoperative pancreatic fistula Grades B and C and bile leakage were significantly associated with severe postpancreatectomy hemorrhage on multivariable logistic regression. For patients with postpancreatectomy hemorrhage Grade C, the onset of bleeding was in median 13 days after the index operation, ranging from 1 to 85 days. Twelve patients (63.2%) had sentinel bleeds. Surgery lead to definitive hemostatic control in six of eight patients (75.0%). Angiography was able to localize the bleeding source in 8/10 (80.0%) cases. The success rate of angiographic hemostasis was 8/8. (100.0%). The mortality rate among patients with postpancreatectomy hemorrhage Grade C was 2/19 (10.5%), and both fatalities occurred late as a consequence of eroded vessels in association with pancreaticogastrostomy.
Delayed hemorrhage is a serious complication after major pancreatic surgery.Sentinel bleed is an early warning sign. Postoperative pancreatic fistula and bile leakage are important risk factors for severe postpancreatectomy hemorrhage.
In Landspitali University Hospital, magnetic resonance imaging is used non-selectively in addition to mammogram and ultrasound in the preoperative assessment of breast cancer patients. The aim of this study was to assess invasive tumor size on imaging, compare with pathological size and evaluate the impact of magnetic resonance imaging on the type of surgery performed.
All women with invasive breast cancer, diagnosed in Iceland, between 2007 and 2009 were reviewed retrospectively. In all, 438 of 641 (68%) patients diagnosed had preoperative magnetic resonance imaging. Twelve patients treated with neoadjuvant chemotherapy were excluded and 65 patients with multifocal or contralateral disease were assessed separately.
Correlations between microscopic and radiologic tumor sizes were relatively weak. All imaging methods were inaccurate especially for large tumors, resulting in an overall underestimation of tumor size for these tumors. Magnetic resonance imaging under- and overestimated pathological tumor size by more than 10 mm in 16/348 (4.6%) and 26/348 patients (7.5%), respectively. In 19 patients (73%), overestimation of size was seen exclusively on magnetic resonance imaging. For tumors under- or overestimated by magnetic resonance imaging, the mastectomy rates were 56% and 65%, respectively, compared to an overall mastectomy rate of 43%. Of 51 patients diagnosed with multifocal disease on pathology, 19 (37%) were diagnosed by mammogram or ultrasound and 40 (78%) by magnetic resonance imaging resulting in a total detection rate of 84% (43 patients). Fourteen (3%) patients were diagnosed preoperatively with contralateral disease. Of those tumors, all were detected on magnetic resonance imaging but seven (50%) were also detected on mammogram or ultrasound or both.
Our results suggest that routine use of magnetic resonance imaging may result in both under- and overestimation of tumor size and increase mastectomy rates in a small proportion of patients. Magnetic resonance imaging aids in the diagnosis of contralateral and multifocal disease.
Our aim was to evaluate the incidence and type of severe complications in adult primary and incisional ventral hernia surgery reported to the National Patient Insurance Centre in Finland during 2003–2010.
The Finnish National Patient Insurance Centre covers the whole country and handles financial compensation for patients’ injuries without proof of malpractice. All the claims concerning ventral hernioplasties in the Centre between the years 2003 and 2010 were retrospectively analyzed. The annual numbers of primary and incisional ventral hernioplasties in Finland were obtained from the National Hospital Discharge Register.
During the study years, 25,738 ventral hernia operations were performed and 127 claims from the whole country were reported to the Patient Insurance Centre. Overall rate of claims was 4.9/1000 hernia procedures. For primary hernias, 16,243 ventral hernioplasties (817 laparoscopic, 15,426 open) were performed and 41 complications were reported. The most common complication was infection (n = 28, 68%) followed by pain and hernia recurrence (n = 6, 15% in both), large hematoma (7%), bowel lesion (5%), urological injuries (2%), or severe bleeding (2%). In incisional hernioplasties, the rate of claims was 9.1/1000 operations (9495 operations, 86 claims). The most common complication reported was infection (n = 42, 49%) followed by hernia recurrence in 25 cases (29%) and bowel lesion in 24 cases (28%). Major complications (n = 15, 17%) consisted mainly of bowel lesions in laparoscopic operations. There was significantly more claims after laparoscopic than open hernioplasties (p = 0.001).
The claims for financial compensation for injuries related to primary and incisional hernioplasties are quite uncommon. Major complications, though comparatively rare, are significantly more common after laparoscopic operations.
Electrical burns are uncommon, but they result in high morbidity and mortality due to severe tissue damage. The purpose of this study is to analyze epidemiological variables of electrical injuries and identify preventable measures through them.
We retrospectively analyzed the clinical records of 625 patients admitted to Hangang Sacred Heart Hospital’s Department of Plastic Surgery from January 2005 to December 2011. We divided the patients into two groups: (1) low-voltage injury (under 1000 V) and (2) high-voltage injury (over 1000 V). We reviewed the following variables: age, sex, total burn surface area, injury type and mode, and surgical modalities.
The mean age of all patients was 33.4 ± 18.2 years. The ratio of males to females was 13.5 in the whole group. The mean total body surface are burned was 14.0% ± 13.8% in total. The majority of electrical burns in the low-tension group and high-tension group occurred in patients under 20 years and in patients aged 40–59 years, respectively. Steel chopstick insertions and high-voltage electrical work/repair were the most common injury modes in the low-tension group and the high-tension group, respectively. Groin and abdominal distant flap surgeries were commonly performed in both groups. It is recommended that these risks be prevented through education and safety measures to reduce the incidence of electrical injuries.
Reduction mammaplasty is an increasingly common plastic surgical procedure. In the United States, majority of breast reductions are performed as outpatient surgery. In European public health care, outpatient breast reductions have still been rare. Our aim was to retrospectively determine clinical outcome and the success rate of outpatient reduction mammaplasty.
A total of 110 consecutive patients underwent bilateral reduction mammaplasty with a minimum resection of 200 g per breast in an outpatient unit between 2006 and 2009. A comparison group consisted of 28 inpatients. Demographic data and pre-, intra-, and postoperative events as well as complications were recorded.
A total of 83 outpatients (75%) were successfully discharged on the day of operation. Reasons for unexpected overnight admission were lack of adult company for the first postoperative night (13 patients, 12%), surgeon’s wish (4 patients, 4%), hematoma requiring evacuation (5 patients, 5%), nausea (3 patients, 3%), and pain (2 patients, 2%). Minor complications, especially delayed healing, were common (45 patients, 41%), but major complications were rare (18 patients, 16%). Complication rate was not increased in the outpatient group. Increased duration of operation correlated with increasing complications.
Reduction mammaplasty can be successfully and safely performed as an outpatient procedure in European public health care.
The aim of this study was to provide information on incidences and severity of recreational alpine skiing and snowboarding injuries in Northern Finland and to discuss possible preventive measures to reduce the number and severity of injuries in the future.
This retrospective study consists of all injured skiers and snowboarders in the Levi Ski Resort during the 2006–2012 winter seasons. The Levi Ski Resort has a SKIDATA® system which records automatically every ski-lift run taking place. The emergency system of the resort registers the data (conditions during the injury, patient characteristics, and observed and/or suspected injuries) of all injured persons they meet. The severity of injury is defined by the needed level of care: Grade 1 (treated by the emergency system with no need for further referral), Grade 2 (referral to the local primacy care clinic), Grade 3 (transfer to hospital by ambulance), and Grade 4 (transfer to tertiary care by helicopter).
During the 6-year study period, there were 29,576.132 lift runs and 2911 injuries were met by the emergency system, resulting in the average injury incidence of 0.98 injuries per 10,000 lift runs. Vice versa, the average number of the ski-lift rides needed to generate one injury was 10,160. The knee injuries of the skiers constituted almost one-third of all cases, whereas snowboarders sustained more injuries to the upper limb and axial areas.
Skiing and snowboarding are related to a relatively high risk of injury. The most common injuries affect the knee in skiers and the upper extremity, especially the wrist, in snowboarders. A continuous and systematic review of injuries is needed to monitor the effects of changes made in terms of the safety.
Retrosternal goiter may cause symptoms of airway obstruction and dysphagia, but often it is asymptomatic and is increasingly detected incidentally with imaging investigations. Consensus has been reached that sternotomy is not necessary in most cases, as a collar incision normally suffices. Yet, surgery for retrosternal goiter is associated with more complications than cervical goiter. There is controversy over whether patients with asymptomatic retrosternal goiter should be operated. Proponents argue that retrosternal goiter may be a risk for thyroid cancer and may progress to later cause symptoms, although clear evidence is missing.
Between 1984 and 2012, 132 patients underwent surgery for benign retrosternal goiter. Preoperatively, the benign nature was clinically apparent and confirmed by fine needle cytology in most cases.
Sternotomy was required in only 4 of the 132 operations. Three patients died in the postoperative period. The risk of morbidity and mortality was 16.7% in 60 patients with compression symptoms and 13.9% in 72 patients without compression symptoms (P = 0.808). Histology revealed no case of unsuspected cancer.
Surgery for retrosternal goiters involves a higher risk for complications than do cervical goiters, and the risk does not differ between patients with and without symptoms. This, and the fact that no patient in this study had unsuspected cancer, calls into question the rationale for surgery in patients with asymptomatic retrosternal goiter without suspected cancer.
Osteoporosis is a major health concern in elderly population. Low-trauma fractures offer one way of identifying these patients for treatment. Population-specific incidences of osteoporotic fractures are essential to validate tools for clinical decision making.
To evaluate population-based osteoporotic fracture incidences in Central Finland, we performed a manual search of low-trauma fractures 2005–2006 from the records of all the local health-care organizations treating trauma patients. We identified low-trauma fracture patients from radiology reports from five health centers serving the inhabitants of nine municipalities and from the patient records of two hospitals in Central Finland. The manually collected data were then compared against data from the Finnish Health Care Register.
The crude incidence of all osteoporotic fractures in 2005–2006 in the population aged 50 years was 1254/100,000 person years: 694/100,000 person years in men and 1718/100,000 person years in women. Fracture numbers derived from register data were similar to those manually collected for hip and humerus fractures, but clearly smaller than those for wrist and ankle fractures.
Population-based low-trauma fracture incidences, reported here for Finland, constitute a basis for calibration of fracture risk evaluation tools (e.g. the World Health Organization fracture risk evaluation tool, FRAX). This study showed that register data underestimate the incidences of, in particular, distal radius and ankle fractures.
A new technique for the repair of inguinal hernia, called Onstep, has been described. This technique places the mesh in the preperitoneal space medially and between the internal and external oblique muscles laterally. The Onstep technique has not yet been described outside the inventors’ departments. This study was based on the first 80 patients operated by the Onstep technique in a general surgical department. The objective of the study was to investigate postoperative pain and complications following the Onstep repair of inguinal hernia.
A total of 80 patients, operated in our department, were followed up in the medical files and contacted by letter. Patients were asked to fill out the Inguinal Pain Questionnaire, Carolinas Comfort Scale, and the Activity Assessment Scale, in order to assess postoperative pain.
No perioperative complications occurred. The response rate was 85% on the mailed questionnaires. No patients had any activities they were not able to perform. Activity Assessment Scale results: 80.3% did not have substantial pain-related impairment of daily function. Carolinas Comfort Scale results: 94.8% did not have a symptomatic repair. Inguinal Pain Questionnaire results: 95.5% reported no pain or pain that was easily ignored.
It seems from this study that the Onstep technique is a safe method for inguinal hernia repair regarding perioperative and postoperative complications. The postoperative pain seems to be equal to or lower than after the Lichtenstein technique.
Resuscitative thoracotomy is a dramatic operation performed in otherwise unsalvageable trauma patients. Analysis of its efficacy is based mostly on institutional series compiling the experience of multiple surgeons. This study aimed to report more consistent information by describing the resuscitative thoracotomy practice of a single surgeon and its evolution during more than two decades.
A retrospective review of consecutive patients who underwent resuscitative thoracotomy in July 1990 to December 2012. Demographics, mechanism of injury, signs of life, injuries, and outcomes were analyzed. Comparisons were made between penetrating and blunt trauma patients and between pre- and post-introduction of a selective resuscitative thoracotomy protocol.
Sixty-seven resuscitative thoracotomies were performed. Most patients were males (84%), and mean age was 38 years. Mechanism of injury was stab wounds (54%, 36), blunt force (25%, 17), and gunshot wounds (21%, 14). Survival was 22% (8/36), 0% (0/17), and 7% (1/14), respectively. All nine survivors had signs of life upon admission, and survival in patients with signs of life on admission was 25% (8/32) in the stab wounds group and 8% (1/12) in the gunshot wounds group. Seven of the nine survivors (78%) were discharged neurologically intact. The most common injury in survivors was cardiac laceration with tamponade (6/9) and lung injury (3/9). Three survivors had a cardiac and lung injury, one had a lung hilum injury, and one had an abdominal inferior vena cava laceration. The switch to resuscitative thoracotomy protocol (2002) improved overall (31 vs 8%, p < 0.05) and penetrating trauma (45 vs 10%, p < 0.05) survival, eliminated resuscitative thoracotomy in patients presenting with no signs of life, and tended to reduce resuscitative thoracotomy utilization in blunt trauma patients.
This single-surgeon series supports that resuscitative thoracotomy can be lifesaving in selected penetrating trauma patients in extremis. A switch to a selective evidence-based protocol increased overall and penetrating resuscitative thoracotomy survival and limited resuscitative thoracotomy performance to patients arriving with signs of life.
Diagnostic laparoscopy is the ultimate tool to evaluate the appendix. However, the intraoperative evaluation of the appendix is difficult, as the negative appendectomy rate remains 12%–18%. The aim of this study is to analyze the intraoperative motive for performing a laparoscopic appendectomy of an appendix that was proven to be noninflamed after histological examination.
In 2008 and 2009, in five hospitals, operation reports of all negative laparoscopic appendectomies were retrospectively analyzed in order to assess the intraoperative motive for removing the appendix.
A total of 1,465 appendectomies were analyzed with an overall negative appendectomy rate of 9% (132/1,465). In 57% (841/1,465), a laparoscopic appendectomy was performed, with 9% (n = 75) negative appendectomies. In 51% of the negative appendectomies, the visual assessment of the appendix was decisive in performing the appendectomy. In 33%, the surgeon was in doubt whether the appendix was inflamed or normal. In 4%, the surgeon was aware he removed a healthy appendix, and in 9%, an appendectomy was performed for different reasons.
In more than half of the microscopic healthy appendices, the surgeon was convinced of the diagnosis appendicitis during surgery. Intraoperative laparoscopic assessment of the appendix can be difficult.
Breast reconstruction has been shown to improve quality of life. However, factors involved in long-term patient satisfaction are largely unknown. Our aim was to evaluate patient satisfaction and donor-site morbidity in five types of breast reconstruction.
A prospectively collected database of all breast surgery patients at Hospital Rudolfstiftung, Vienna, Austria, was searched for five types of breast reconstruction (2000–2006): implant, latissimus dorsi-flap, latissimus dorsi-flap with implant, free transverse rectus abdominis musculocutaneous-flap, and deep inferior epigastric perforator-flap. Patients were sent a study-specific questionnaire to assess satisfaction. Short-form 36-item health survey was used to analyze (quality of life), and complication data were retrieved from the database and assessed during a follow-up visit.
There were 257 patients identified, of whom, 126 responded to the survey (17 implant, 5 latissimus dorsi + implant, 64 latissimus dorsi, 22 transverse rectus abdominis musculocutaneous, and 18 deep inferior epigastric perforator reconstructions). No statistical differences were found in complication or reoperation rates. Deep inferior epigastric perforator–flap patients were significantly more satisfied compared to patients from the implant group (p = 0.007). However, there was no significant difference regarding quality of life scores among the groups. After logistic regression analysis, only "impairment on daily life" showed to be independently correlated with patient satisfaction. This contrary to both operation type and complication rate which did not correlate with patient satisfaction.
Our results indicate that operation type, complication rate, and revision rate did not independently correlate with patient satisfaction. Therefore, to further improve patient satisfaction, future research should be focused on other pro-operative factors, for example, patient education, expectations, and personality characteristics.
Resuscitative thoracotomy is a heroic procedure that may offer the only survival hope for trauma patients in extremis. However, this operation has been the subject of much debate and its use, feasibility, outcomes, and cost are being continuously re-evaluated.
This is a review of the most current (after 2000) literature on resuscitative thoracotomy, based on computer database searches for studies on resuscitative thoracotomy, emergency department thoracotomy, and emergency thoracotomy. Studies were selected for inclusion in this review based on their relevance and contribution to our understanding of resuscitative thoracotomy.
A total of 37 studies were included, and the following resuscitative thoracotomy–related topics were critically discussed: indications, biochemical profile, long-term outcome, organ donation, pre-hospital use, military use, international aspects, intra-aortic balloon occlusion, suspended animation, and cost and occupational exposure.
This review demonstrates that the indications for resuscitative thoracotomy become clearer and that new information is available regarding its use in the pre-hospital urban environment and military settings. Furthermore, it points to new strategies to supplement resuscitative thoracotomy including intra-aortic balloon occlusion and suspended animation. Finally, it sheds light on the long-term outcomes, organ donation, and cost and occupational exposure following resuscitative thoracotomy.
Treatment of open fractures continues to be a challenge for orthopedic and trauma surgeons, and early treatment recommendations, which persist in the literature for decades, often do not have supporting data.
This is a critical review of the literature surrounding controversies in the initial management of open fractures. It also focuses on the utility of negative pressure dressings in the care of associated complex wounds. Studies were selected based on their relevance to the treatment of open fractures.
A total of 40 studies were included. The following topics were critically discussed: timing of initial debridement, antibiotic coverage, utility of obtaining cultures, and timing of wound closure.
The majority of open fractures require urgent, not emergent, irrigation and debridement. Antibiotics are essential in preventing infection in open fractures. Timely wound closure after all necrotic tissue has been debrided decreases complications in open fractures. Finally, negative pressure wound therapy has dramatically changed the care of associated complex wounds.
Post-trauma resuscitation has evolved based on civilian and wartime experiences over the last decade. Similarly, data from large multicenter randomized trials have changed the management of critically ill trauma patients in the intensive care unit.
This is a review of the literature focusing on areas relevant to the management of trauma patients in the intensive care unit.
The following topics are included: (1) ventilator management, (2) trauma sepsis, (3) use of vasopressors in hemorrhage, (4) glucose control, (5) nutrition, and (6) hemodynamic monitoring.
This review demonstrated the most recent data of trauma-related critical care. Further studies will be needed to settle growing controversies in the management of critically injured patients.
The indications for operative treatment of lateral tibial plateau fractures are still controversial. The objective of this study was to determine whether residual articular surface depression and valgus malalignment of plated lateral tibial plateau fractures at medium-term follow-up affect the clinical and radiographic outcomes.
A chart review of patients with operatively treated (AO type B3.1) tibial plateau fractures that were admitted to our level I trauma center between 2002 and 2008 was performed. Out of 123 patients, 73 were available to participate in a clinical and radiographic follow-up examination. The mean follow-up time was 54 months. Patients were clinically assessed and completed the Lysholm knee score and Western Ontario and McMaster Universities Osteoarthritis Index. Maximal articular surface depression, radiological mechanical axis, and degree of posttraumatic osteoarthritis were evaluated from standing radiographs.
Patients with valgus malalignment of 5° or greater at follow-up developed more advanced osteoarthritis (Kellgren–Lawrence grade 3–4) than patients with a normal mechanical axis (p = 0.006). Similarly, patients with articular depression greater than 2 mm at follow-up also developed more advanced osteoarthritis compared to patients with a depression of 2 mm or less (p = 0.001). The degree of valgus malalignment or articular depression had no effect on the Western Ontario and McMaster Universities Osteoarthritis Index or Lysholm scores.
The postoperative articular congruity and normal mechanical axis of the lower leg after plate fixation in lateral tibial plateau fractures seem to have a role in prevention of posttraumatic osteoarthritis but does not appear to predict clinical outcome at medium-term follow-up. The role of initial dislocation and associated cartilage damage in the development of osteoarthritis following these fractures is still unknown.
While combat casualty care shares many key concepts with civilian trauma systems, its unique features mandate certain practices that are distinct from the civilian ones.
This is a review of the most current literature on combat casualty care, based on computer database searches for studies on combat casualty care and military medicine. Studies were selected for inclusion in this review based on their relevance and contribution.
Over the last decade, meticulous, international data collection and research efforts have led to significant improvements in military trauma care. Combat medicine has focused on the causes of preventable deaths and targeted on bleeding control and resuscitation strategies, as well as improved evacuation. En route care and forward surgical interventions have resulted in unprecedented low fatality rates and the saving of more lives.
This overview of the developments in combat casualty care in recent years emphasizes medical practices that are characteristic of combat medicine, yet with the potential to save lives in other scenarios, as well.
To validate the Swedish Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks) concerning completeness and correctness of entered data for cholecystectomies and evaluating the effect of repeated audits. It is crucial for any register to obtain a high accuracy in order to be a credible and reliable source for quality evaluation, research, and development.
Completeness was determined by cross-matching the register with the Swedish National Patient Register. Completeness and overall correctness were assessed by comparing registered data to medical records. Correctness for rare occasions, such as bile duct injuries, was evaluated by comparing with claims sent to the Swedish Patient Insurance.
Of 64,538 cholecystectomies, 82.9% of the operations were registered in GallRiks and the coverage increased over time. By random sample, 94,919 sets of data were available for comparison at the first and second audit and the entries were found to be correct in 97.2% and 98.2% cases, respectively. A 100% correctness for bile duct injuries (n = 40) was seen when the index-operation was registered in GallRiks.
GallRiks demonstrates high completeness, high correctness of entered data, and no indications of failure to report serious adverse events. Repeated audits increased the quality of registered data. GallRiks may be used for clinical evaluation on local and national level and the database enables scientific studies to be performed.
Minimally invasive surgery is increasingly being used in trauma surgery as both a diagnostic and a therapeutic tool. However, significant debate regarding the accuracy, safety, and indications for minimally invasive surgery in trauma continues to impede widespread acceptance of these techniques among trauma surgeons.
Herein, we report a contemporary review of the current role of both laparoscopy and thoracoscopy in modern trauma surgery. Literature search was performed using PubMed database and the following keywords: "Trauma," "Minimally Invasive Surgery," "Laparoscopy," and "Thoracoscopy."
Current recommendations advocate for the use of laparoscopy as a diagnostic tool in penetrating trauma for the diagnosis of diaphragm injuries and peritoneal violation. A significant body of research demonstrates that laparoscopy in select hemodynamically normal patients can significantly decrease nontherapeutic laparotomy rates and hospital costs and is highly sensitive and specific with very low missed injury rates, including small bowel injuries. Laparoscopic repairs to a wide breadth of abdominal and thoracic injuries have been reported with impressive results. Adherence to a standardized laparoscopic examination system and routine use of laparoscopy in elective or acute care practice strongly influence positive results with minimally invasive surgery in trauma. Video-assisted thoracoscopic surgery is most commonly used for evaluation of diaphragm, evacuation of retained hemothorax, and management of ongoing bleeding post-trauma.
Minimally invasive surgery does offer several advantages compared to traditional open surgery and should be considered as an additional tool in the trauma surgeon’s armamentarium in the care of select injured patients.
In patients with severe pelvic fractures, exsanguinating hemorrhage represents the major cause of death within the first 24 h. Despite advances in management, the mortality rate in these patients remains significantly high. Recently, multiple treatment algorithms have been proposed for patients with severe pelvic fractures; however, the optimal modalities in particular in the hemodynamically unstable patient are still a matter of lively debate.This review article focuses on the recent body of knowledge on the different treatment options in patients with severe pelvic fractures and proposes the possible role of each modality in the management of these patients.
The MEDLINE database was searched for medical literature addressing the management of severe pelvic fractures with specific attention given to recent, clinically relevant publications.
Angiography and embolization have emerged as excellent methods for addressing arterial bleeding. Mechanical pelvic stabilization and surgical hemostasis by pelvic packing, on the other hand, may effectively control venous bleeding and bleeding from the fractured bony surface. However, since there is no precise way to determine the major source of bleeding that is responsible for the hemodynamic instability, controversy remains over the timing and optimal order of angiography, mechanical pelvic stabilization, and packing.
The author’s own approach to these patients includes angiographic embolization as a first-line treatment only in hemodynamically stable patients with an arterial blush seen in the computed tomography scan, indicating acute arterial bleeding. Hemodynamically unstable patients are immediately transferred to the operating room, where pelvic packing and mechanical stabilization of the pelvic ring are carried out. Optionally, a subsequent postoperative angio-embolization is performed if signs of further bleeding remain present.
Appendicitis is a frequent reason for hospital admissions. Elevated C-reactive protein, white blood cell count, and serum bilirubin have been suggested as individual markers for appendicitis and appendiceal perforation. The aim of this study was to analyze if a combination of serologic markers could increase the prognostic accuracy of diagnosing non-perforated and perforated appendicitis.
Demographic data, histological findings, blood tests, and clinical symptoms were collected on all patients who underwent a diagnostic laparoscopy, a laparoscopic appendectomy, or conventional (open) appendectomy between May 2009 and May 2012 from a surgical department. The patients were grouped into those with either perforated appendicitis, non-perforated appendicitis, or differential diagnosis. Univariate and multivariate models were used to identify which markers were useful in predicting acute and perforated appendicitis, and receiving operating characteristics curves were used to find the specificity, sensitivity, and the negative and positive predictive values.
A total of 1008 patients were operated under suspicion of appendicitis. From these, 700 patients had a pathologically verified inflamed appendix and 190 had a perforated appendix. Patients with acute appendicitis had significantly higher blood levels of white blood cell, bilirubin, C-reactive protein, and alanine transaminase than patients without appendicitis. Patients with perforated appendicitis had significantly higher levels of white blood cell, bilirubin, and C-reactive protein than patients with non-perforated appendicitis. The highest positive predictive value to discriminate between acute appendicitis and non-appendicitis was of a linear regression model combining white blood cell count, bilirubin, and alanine transaminase. C-reactive protein levels and a linear regression model, including white blood cell count, bilirubin, and C-reactive protein levels as variables, had the highest negative predictive values when discriminating between perforated and non-perforated appendicitis.
Combining blood markers was useful in predicting appendicitis and perforated appendicitis. In addition to C-reactive protein and white cell count, blood levels of bilirubin, and alanine transaminase may be useful.
Despite several potential complications of elastic intramedullary nailing, it is currently the treatment of choice for femoral diaphyseal fractures in school-aged children. This study aimed to critically evaluate the complications of titanium elastic nailing in pediatric femoral shaft fractures.
This study evaluated patients with a diaphyseal femoral fracture treated with titanium elastic nailing (TEN) in Tampere University Hospital in Finland. The study group included 32 children with a mean age of 9 years during a 5-year period, from 1 January 2003 to 31 December 2007. Data were collected from medical records and x-rays. Mean follow-up time was 42 months.
Of 32 patients, 9 (28%) reported a postoperative complication. Complications were associated with nail prominence in five (16%) patients and instability in four (12%) patients. In patients with nail prominence, the titanium elastic nailing–nail ends were unbent and 10–35 mm outside the cortex of the distal femur. The nail prominence caused pain and delayed knee mobilization until the nail was removed after a mean time of 4 months. In patients with fracture instability, the mean titanium elastic nailing–nail/medullary canal diameter ratio was 46% and periosteal callus formation was 5.4 mm at the first control. In those with stable fractures, the values were 66% and 9.2 mm, respectively.
Based on this study, two types of pitfalls in a small volume center were found. Titanium elastic nail ends were left unbent and too long. We recommend palpating the nail ends to exclude nail prominence and to verify free movement of the knee after nail cutting and bending. Fracture instability was caused by inserting titanium elastic nailing–nails that were too narrow. To avoid this complication, careful preoperative planning to select the proper-size titanium elastic nailing–nails and intraoperative testing of fracture stability under continuous fluoroscopy after the operation is advised.
Complications in the biliary tract occur in 5%–30% after liver transplantation and the main part of the complications is successfully managed with endoscopic retrograde cholangiopancreaticography (ERCP). The incidence and risk factors for post-ERCP complications in liver transplantation patients are not well described. Our objective was to define the frequency of post-ERCP complications in liver transplantation patients at the Abdominal Center, Rigshospitalet, the only Liver Transplantation Center in Denmark.
Retrospective study of all ERCPs performed in liver transplantation patients during a 9-year period.
A total of 292 ERCPs were included. Overall post-ERCP complications occurred in 24 procedures (8.2%): pancreatitis in 8 (2.7%), bleeding in 5 (1.7%), and cholangitis in 13 (4.5%) procedures. Simultaneous pancreatitis and cholangitis, and simultaneous bleeding and cholangitis occurred after two procedures, respectively. Multivariate analysis concerning overall complications identified biliary sphincterotomy (p = 0.006) and time since liver transplantation within 90 days postoperatively (p = 0.044) as risk factors for post-ERCP complications. Specifically concerning post-ERCP pancreatitis (PEP), it was found that pre-ERCP cholangitis was another independent risk factor for PEP (p = 0.026). Stent in the biliary tract prior to ERCP seemed to be protective (p = 0.041).
Complications were of surprisingly mild degree. The rates of post-ERCP complications in our study were in line with previous studies with liver transplantation patients. Cholangitis prior to ERCP may be another risk factor for post-ERCP pancreatitis.
Complex nontraumatic foot lesions often lead to major lower-limb amputation in diabetic patients. We aimed to evaluate outcome of free flap transfer in such cases.
A total of 11 consecutive diabetic patients, hospitalized between 2007 and 2012 at a university central hospital for a free flap transfer, were followed until September 2013. Amputation-free survival, patient survival, and complete wound healing were defined as primary endpoints. Healing time of tissue lesions was analyzed. All pre- and postoperative data were retrospectively collected from hospital charts.
Complete tissue healing at 6 and 12 months after free flap transfer were 55% (6/11) and 82% (9/11), respectively. The median time to complete tissue healing was 123 days (range, 45–207 days). Overall limb salvage, survival, and amputation-free survival rates at 12 months were 90%, 91%, and 82%, respectively. The clinically important endpoint, namely, amputation-free survival with completely healed wounds, was attained in 9 of 11 patients at 1 year.
Free tissue transfer enables successful wound healing and limb salvage rather than amputation in selected diabetic patients with difficult-to-heal wounds. Complete healing of tissue lesions is slow even after successful surgery. Preoperative assessment of the condition of patients is the key to success.
Fast-track protocols have been used to optimize the perioperative care and to enhance postoperative recovery. This study examined short-term clinical outcomes and determinants affecting the length of postoperative hospital stay.
From 2007 to 2009, 180 patients underwent laparoscopic or open bowel resection (N = 138) or sacrocolporectopexy (N = 42) in the Central Hospital of Central Finland for various colorectal diseases in the fast-track setting. The main measures of outcome were time to functional recovery, 30-day morbidity, and readmission rates, with hospital stay and patient satisfaction as secondary outcomes.
There were no deaths. Time to functional recovery was median 2 (interquartile range 2–3) days. The overall 30-day postoperative morbidity was 14.5% after bowel resection and 0% after sacrocolporectopexy. Relaparotomy rate was 3.6% and 30-day readmission rate 7.2%. Postoperative hospital stay was median 3 days after small bowel and ileo-colic resection, 4 days after segmental colectomy, and 6 days after rectal resection and subtotal colectomy. Patient’s body mass index > 30 kg/m2, malignant disease, complexity of surgery, recovery of bowel function later than 2 days after surgery, time to functional recovery > 2 days and postoperative morbidity were patient- and treatment-related determinants increasing postoperative hospital stay. Protocol compliance–related determinants increasing postoperative hospital stay were intake of normal food and mobilization ≥ 6 h/day later than 2 days after surgery and removal of urinary catheter later than 1 day after surgery.
Postoperative functional recovery was fast, morbidity and readmission rates were low, and postoperative hospital stay short indicating that fast-track care should form the mainstay of elective colorectal surgery.
Stiffness after a rotator cuff tear is common. So is stiffness after an arthroscopic rotator cuff repair. In the literature, however, postoperative restriction of passive range of motion after open rotator cuff repair in shoulders with free passive range of motion at surgery has seldom been recognized. We hypothesize that this postoperative stiffness is more frequent than recognized and slows the primary postoperative healing after a rotator cuff reconstruction. We wondered how common is postoperative restriction of both active and passive range of motion after open rotator cuff repair in shoulders with free passive preoperative range of motion, how it recovers, and whether this condition influences short- and long-term results of surgery. We also explored factors predicting postoperative shoulder stiffness.
We retrospectively identified 103 postoperative stiff shoulders among 416 consecutive open rotator cuff repairs, evaluating incidence and duration of stiffness, short-term clinical results and long-term range of motion, pain relief, shoulder strength, and functional results 3–20 (mean 8.7) years after surgery in 56 patients.
The incidence of postoperative shoulder stiffness was 20%. It delayed primary postoperative healing by 3–6 months and resolved during a mean 6.3 months postoperatively. External rotation resolved first, corresponding to that of the controls at 3 months; flexion and abduction took less than 1 year after surgery. The mean summarized range of motion (flexion + abduction + external rotation) increased as high as 93% of the controls’ range of motion by 6 months and 100% by 1 year. Flexion, abduction, and internal rotation improved to the level of the contralateral shoulders as did pain, strength, and function. Age at surgery and condition of the biceps tendon were related to postoperative stiffness.
Postoperative stiff shoulder after open rotator cuff repair is a common complication resolving in 6–12 months with good long-term results.
Reduction mammaplasty is a popular procedure in plastic surgery. Occasionally, occult invasive breast carcinoma or findings demonstrating increased risk of breast cancer occur in reduction mammaplasty specimens. The incidences have been studied elsewhere, but in Finland, the data on this subject are lacking. Our aim was to analyze the incidence of occult invasive and in situ carcinoma and benign breast disease causing increased risk of breast cancer in reduction mammaplasty specimens. We also analyzed preoperative mammograms and ultrasound images and compared findings with reduction mammaplasty specimens.
We performed a retrospective study of 100 women who underwent reduction mammaplasty during 1 January 2007 to 30 April 2009 in Jorvi Hospital day-surgery unit. Demographic data, findings in preoperative imaging, pathology reports, postoperative follow-up, and retrospective reanalysis of preoperative imaging were recorded.
Histological abnormality occurred in 14.6% of the patients. In situ carcinoma was diagnosed in 4.5% of the patients, and findings demonstrating increased risk of breast cancer were diagnosed in 13.5% of the patients. More than one lesion demonstrating increased risk of breast cancer was diagnosed in 4.5% of the patients. No invasive carcinoma occurred. Preoperative mammogram was performed for the majority (94.0%) of the patients.
We detected a considerable amount of findings in reduction mammaplasty specimens with prognostic value with regard to future breast cancer risk. We recommend histological analysis for reduction mammaplasty specimens and focus attention on systematically performed preoperative imaging.
Crew resource management–based operating room team training will be an evident part of future surgical training. Hybrid simulation in the operating room enables the opportunity for trainees to perform higher fidelity training of technical and non-technical skills in a realistic context. We focus on situational motivation and self-efficacy, two important factors for optimal learning in light of a prototype course for teams of residents in surgery and anesthesiology and nurses.
Authentic operating room teams consisting of residents in anesthesia (n = 2), anesthesia nurses (n = 3), residents in surgery (n = 2), and scrub nurses (n = 6) were, during a one-day course, exposed to four different scenarios. Their situational motivation was self-assessed (ranging from 1 = does not correspond at all to 7 = corresponds exactly) immediately after training, and their self-efficacy (graded from 1 to 7) before and after training. Training was performed in a mock-up operating theater equipped with a hybrid patient simulator (SimMan 3G; Laerdal) and a laparoscopic simulator (Lap Mentor Express; Simbionix). The functionality of the systematic hybrid procedure simulation scenario was evaluated by an exit questionnaire (graded from 1 = disagree entirely to 5 = agree completely).
The trainees were mostly intrinsically motivated, engaged for their own sake, and had a rather great degree of self-determination toward the training situation. Self-efficacy among the team members improved significantly from 4 to 6 (median). Overall evaluation showed very good result with a median grading of 5. We conclude that hybrid simulation is feasible and has the possibility to train an authentic operating team in order to improve individual motivation and confidence.
To evaluate the efficacy and safety of a modified laparoscopic ureterolithotomy for the treatment of upper ureteral stones; this method involved the use of a Carter–Thomason fascial closure device, a broken 15th blade.
From February 2009 to December 2012, 38 patients with unilateral upper ureteral stones were examined and classified into 2 groups: one group underwent conventional laparoscopic ureterolithotomy (n = 21) and the other group underwent modified laparoscopic ureterolithotomy (n = 17). The modified laparoscopic ureterolithotomy consisted of the use of a Carter–Thomason fascial closure to extract the black silk along with the nylon tape. The ureter incision was made with a modified instrument consisting of a needle holder with a broken 15th blade tip.
Patient demographics were similar in both groups. No significant differences were detected between the conventional laparoscopic ureterolithotomy and modified laparoscopic ureterolithotomy groups with respect to operating time, estimated blood loss, and stone clearance rates. Drain-indwelling times were significantly shorter in modified laparoscopic ureterolithotomy patients than in conventional laparoscopic ureterolithotomy patients (3.2 ± 1.3 vs 4.7 ± 1.5 days). Hospital stay was significantly lesser in modified laparoscopic ureterolithotomy patients than in conventional laparoscopic ureterolithotomy patients (4.3 ± 1.2 vs 5.2 ± 1.2 days). No differences were detected in the ureteral stent indwelling time for the two groups. The use of the Carter–Thomason fascial closure facilitated ureter handling, and the use of a needle holder with a broken 15th blade tip enabled a sharp and precise ureteral incision. Our method allows early removal of the drain and thus earlier patient discharge.
Patients with penetrating trauma of the major vessels of the chest are infrequently encountered. This is due to the fact that the majority of these patients die on scene, as well as due to the overall dramatic decline in the incidence of penetrating trauma in the Western world. A certain proportion of survivors are physiologically stable and can be transferred to adequate care. Patients who are physiologically unstable must be dealt with by the surgeons available without delay. Rapid diagnosis and operation can salvage patients who would otherwise be lost, and all general surgeons should be capable of recognizing these injuries and intervening if a trauma and/or cardiothoracic surgeon is not immediately available.
Technical description of practical emergency surgery approaches to patients bleeding to death from penetrating mediastinal vessel injuries.
The scope of this review familiarizes the "uninitiated" surgeon with the operative management of this rare and lethal type of injuries. Technical aspects are described, and pitfalls as well as tips and tricks of the trade are discussed.
Patients with penetrating injuries to the mediastinal vessels can be saved by swift and knowing operative management of this rare and lethal type of injuries, even if a trauma and/or cardiothoracic surgeon is not immediately available.
The long-term efficacy of laparoscopic Roux-en-Y gastric bypass in the treatment of morbid obesity has already been demonstrated. Laparoscopic sleeve gastrectomy has shown promising short-term results, but the long-term efficacy is still unclear. The aim of this prospective randomized multicenter study is to compare the results of Roux-en-Y gastric bypass and sleeve gastrectomy.
A total of 240 morbidly obese patients were randomized to undergo either Roux-en-Y gastric bypass or sleeve gastrectomy. The primary end point of study was weight loss, and the secondary end points were resolution of comorbidities and morbidity. The short-term results at 6 months were analyzed.
The mean excess weight loss at 6 months was 49.2% in the sleeve gastrectomy group and 52.9% in the Roux-en-Y gastric bypass group (p = 0.086). Type 2 diabetes was resolved or improved in 84.3% of patients in the sleeve gastrectomy group and 93.3% in the Roux-en-Y gastric bypass group (p = 0.585). The corresponding results for arterial hypertension were 76.8% and 81.9% (p = 0.707) and for hypercholesterolemia 64.1% and 69.0% (p = 0.485). There was no mortality at 6 months. There was one major complication following sleeve gastrectomy and two after Roux-en-Y gastric bypass (p = 0.531). Eight sleeve gastrectomy patients and 11 Roux-en-Y gastric bypass patients had minor complications (p = 0.403).
The short-term results of sleeve gastrectomy and Roux-en-Y gastric bypass regarding weight loss, resolution of obesity-related comorbidities and complications were not different at 6 months.
Postoperative respiratory complications often arise in lung cancer patients after lung resection, although these are often difficult to predict. We sought to identify reliable predictors of early-onset postoperative respiratory complications in lung cancer patients who had moderate-to-severe preoperative respiratory impairment.
This was a prospective observational study that included 107 consecutive lung cancer patients with forced expiratory volume in 1 s <60% of predicted who were scheduled for thoracotomy and lung resection. Preoperative functional assessments included pulmonary function testing by spirometry, single breath diffusion capacity of lung for carbon monoxide, and cardiopulmonary exercise testing. Risk factors for early-onset postoperative respiratory complications that occurred within 30 days postoperatively were sought from among these pulmonary function testing and cardiopulmonary exercise testing results.
By multivariable logistic regression, peak oxygen uptake (V'O2max%; p < 0.001) and the transcutaneous pulse oxygen saturation difference during load exercise (SPO2%; p < 0.001) were independent predictors of postoperative respiratory complications. A receiver operating characteristic curve had an area under the curve of 0.846 for the combination of V'O2max% and SPO2%, while the area under the curve with V'O2max% only was 0.726. From this, the probability of postoperative respiratory complications was
For lung cancer patients with forced expiratory volume in 1 s <60% of predicted, in addition to common preoperative tests, V'O2max% and SPO2% may be an aid for predicting early-onset postoperative respiratory complications.
The aim of this study was to compare the feasibility and early postoperative outcomes between patients undergoing double-barreled wet colostomy and patients undergoing terminal colostomy and ileal conduit for simultaneous urinary and fecal diversion.
Between 1995 and 2012, we had 181 patients in whom it was necessary to make simultaneous urinary and fecal diversion. This is a retrospective study and patients were divided into two groups, depending on the technique applied for the fecal and urinary diversion. The first group consisted of patients undergoing ileal conduit and terminal colostomy and the second group consisted of patients undergoing double-barreled wet colostomy.
Ileal conduit and terminal colostomy was performed in 77 (43%) cases, while wet colostomy was performed in 104 (57%) cases. Median length of stay was shorter for double-barreled wet colostomy (13.1 vs 18.1, p < 0.0001). Median operating times for urinary and fecal diversion were shorter for double-barreled wet colostomy (32 vs 64 min, p < 0.0001). The morbidity was lower for double-barreled wet colostomy (11.5% vs 23.4%, p = 0.0432), retrospectively. The mortality was 3.8% for double-barreled wet colostomy and 10.3% for ileal conduit and terminal colostomy group (p = 0.1282).
Double-barreled wet colostomy is a safe, fast, and simple alternative to traditional ileal conduit and terminal colostomy diversion. The technique is relatively easy to learn, and it reduces the time for urinary and fecal diversion, length of stay, and morbidity rate.
