Show moreBackground: Anastomotic suturing is the Achilles heel of pancreatic surgery. Especially in laparoscopic and robotically assisted surgery, the pancreatic anastomosis should first be trained outside the operating room. Realistic training models are therefore needed. Methods: Models of the pancreas, small bowel, stomach, bile duct, and a realistic training torso were developed for training of anastomoses in pancreatic surgery. Pancreas models with soft and hard tex-tures, small and large ducts were incrementally developed and evaluated. Experienced pancreatic sur-geons (n = 44) evaluated haptic realism, rigidity, fragility of tissues, and realism of suturing and knot tying. Results: In the iterative development process the pancreas models showed high haptic realism and highest realism in suturing (4.6 & PLUSMN; 0.7 and 4.9 & PLUSMN; 0.5 on 1-5 Likert scale, soft pancreas). The small bowel model showed highest haptic realism (4.8 & PLUSMN; 0.4) and optimal wall thickness (0.1 & PLUSMN; 0.4 on -2 to +2 Likert scale) and suturing behavior (0.1 & PLUSMN; 0.4). The bile duct models showed optimal wall thickness (0.3 & PLUSMN; 0.8 and 0.4 & PLUSMN; 0.8 on -2 to +2 Likert scale) and optimal tissue fragility (0 & PLUSMN; 0.9 and 0.3 & PLUSMN; 0.7). Conclusion: The biotissue training models showed high haptic realism and realistic suturing behavior. They are suitable for realistic training of anastomoses in pancreatic surgery which may improve patient outcomes. Show less

Show moreThe need for a common education and training track in surgical oncology across Europe has been emphasized. ESSO provides several hands-on courses for skills training and face-to-face discussions. The core curriculum provides a framework for the overall theoretical requirements in surgical oncology. The UEMS/EBSQ fellowship exam is designed to test core competencies in the candidate's core knowledge in their prespecified area of expertise. A core set of points for each cancer type is lacking. Hence, a condensed outline of themed expected to be covered in the curriculum and relevant to an optimal practice in surgical oncology is provided. This article outlines pancreatic cancer.

Show moreBackground: Treatment of bile duct injuries (BDI) during cholecystectomy depends on the severity of injury and the timing of diagnosis. Standard of care for severe BDIs is hepaticojejunostomy. The aim of this retrospective multi-center study was to assess the optimal timing for repair of BDI with hepaticojejunostomy.Methods: Members of the European-African HepatoPancreatoBiliary Association were invited to report all consecutive patients with hepaticojejunostomy after BDI from January 2000 to June 2016. Patients were stratified according to the timing of biliary reconstruction with hepaticojejunostomy: early (day 0-7), intermediate (1-6 weeks) and late (6 weeks-6 months). Primary endpoint was re-intervention >90 days after the hepaticojejunostomy and secondary endpoints were severe 90-day complications and liver-related mortality.Results: In total 913 patients from 48 centers were included in the analysis. In 401 patients (44%) the bile duct injury was diagnosed intraoperatively, and 126 patients (14%) suffered from concomitant vascular injury. In multivariable analysis the timing of hepaticojejunostomy had no impact on postoperative complications, the need for re-intervention after 90 days nor liver-related mortality. The rate of re-intervention more than 90 days after the hepaticojejunostomy was significantly increased in male patients but decreased in older patients. Severe co-morbidity increased the risk for liver-related mortality (HR 3.439; CI 1.37-8.65; p = 0.009).Conclusion: After BDI occurring during cholecystectomy, the timing of biliary reconstruction with hepaticojejunostomy did not have any impact on severe postoperative complications, the need for re-intervention or liver-related mortality. Individualised treatment after iatrogenic bile duct injury is still advisable. Show less

Show moreBackground. In some patients with colorectal liver metastases it is not clear whether liver resection or isolated liver perfusion is the best treatment option. For instance, the risk of complications after surgery may be so substantial and affect subsequent survival. Aim of the present study is to compare complication occurrence and its effect on survival after liver resection and perfusion. Methods. Patient records of all 225 patients with colorectal liver metastases treated with liver resection (n = 121) or liver perfusion (n = 104) in the period 1997-2006 were reviewed for complications during the initial hospitalisation until 30 d after discharge, and to assess patient survival until the last hospital visit. Median duration of follow-up was 38 mo for overall survival and 22 mo for survival after surgery. Results. Complications occurred less often in patients undergoing resection than perfusion (29.8% versus 49.0%, X-2 = 8.77, P < 0.01). Postoperative mortality rates were similar in both groups (4.1% and 4.8%, respectively). As expected, long term survival after liver surgery was better in the resection group: at 3 y, 60% of patients survived in the resection group, compared with 22% after liver perfusion (log rank X 2 = 35.29 P < 0.001). However, liver resection patients with postoperative complications, had similar survival as perfusion patients without complications (log rank X-2 = 2.45, p = 0.12). This remained after adjustment for differences between the patient groups at time of surgery. Conclusion. Liver resection has superior long-term survival, but survival is significantly reduced by the occurrence of post-surgical complications. When complications occur after liver resection, survival is comparable to patients who underwent uncomplicated liver perfusion. (C) 2010 Elsevier Inc. All rights reserved. Show less
