The incidence of clinically significant anastomotic leaks after upper gastrointestinal surgery is approximately 4 % - 20 %, and the associated mortality can be as high as 80 %. Depending on the clinical presentation, the treatment options are surgery, conservative treatment with external drainage, or endoscopic treatment. This report presents 39 cases of clinically apparent anastomotic leaks or fistulas after surgery for upper gastrointestinal cancers that were treated by endoscopy with insertion of fibrin glue alone (n = 24) or with a combination of Vicryl plug and fibrin glue (n = 15). Thirteen of the 15 patients who underwent Vicryl/fibrin treatments showed complete healing of the anastomotic leak or fistula after one to four sessions. Long-term follow-up results are presented. Postoperative upper gastrointestinal fistulas or anastomotic leaks can be managed successfully with low morbidity by means of endoscopic insertion of Vicryl mesh with fibrin glue, thereby avoiding repeated major surgery and its associated risks.

Summary The aim of our study was to compare the postoperative outcome after liver transplantation (LT) in patients who received a donor liver via standard or rescue allocation (RA). Special emphasize was laid on the effect extended donor criteria might have on the outcome. One hundred and ten LTs have been performed at the University Hospital Aachen, Germany. A total of 49 patients were included in the standard allocation (SA) group and 53 patients in the RA group. The outcome of LT in both groups was evaluated by the length of stay on the intensive care unit (ICU), duration of hospitalization, 1‐year patient survival, 1‐year graft survival, incidence of primary nonfunction and major complications. Patients in group RA had a significant shorter ICU and overall hospital stay. The 1‐year graft survival was 87.8% in group SA and 88.7% in group RA. The 1‐year patient survival was 87.9% in group SA and 96.2% in group RA. The number of re‐LT was 2% in group SA and 7.5% in group RA. Organs that were rejected for transplantation several times can successfully be transplanted through the RA procedure, thereby enlarging the donor pool without negative effects on the quality of LT.

This study has shown that colonic wall changes and enteric neuropathy seem to play a role in the pathogenesis of colonic diverticulosis. None of our results suggest a predisposition for a complicated diverticular disease. Furthermore, the presence of an anatomic sphincter at the rectosigmoid junction could not be detected.

The new Celect filter showed similar in-vitro capture properties as the Gunther Tulip filter and deserves further in-vivo testing.

Introduction. The venovenous/portal venous (VVP) bypass technique has generally become obsolete in liver transplantation (LT) today. We evaluated our experience with 163 consecutive LTs that used a VVP bypass. Patients and Methods. The liver transplant program was started in our center in 2010. LTs were performed using an extracorporal bypass device. Results. Mean operative time was 269 minutes and warm ischemic time 43 minutes. The median number of transfusion of packed cells and plasma was 7 and 14. There was no intraoperative death, and the 30-day mortality was 3%. Severe bypass-induced complications did not occur. Discussion. The introduction of a new LT program requires maximum safety measures for all of the parties involved. Both surgical and anaesthesiological management (reperfusion) can be controlled very reliably using a VVP bypass device. Particularly when using marginal grafts, this approach helps to minimise both surgical and anaesthesiological complications in terms of less volume overload, less use of vasopressive drugs, less myocardial injury, and better peripheral blood circulation. Conclusion. Based on our experiences while establishing a new liver transplantation program, we advocate the reappraisal of the extracorporeal VVP bypass.

Optionally retrievable IVC filters are efficient. Clot size, IVC filter type, and position significantly influence capture rate. Deliberate selection of the most efficient IVC filter and concentric positioning are important to ensure optimal results.

Background There is little and contradictory data about the impact of laparoscopy on wound healing. In this experimental study, gas-related effects of pneumoperitoneum on collagen I mRNA synthesis were analysed separately in fibroblast cultures in vitro.Methods 3T3 mouse fibroblasts were incubated for 1 h with either CO 2 or helium (gas flow: 1 l/min, pressure: 12 mmHg). Control fibroblasts were exposed to room air for 1 h. Hereafter, expression of collagen type IA1 was analysed by real-time PCR.Results Expression of collagen type IA1 analysed was 0.7 times lower after incubation with CO 2 when compared with controls. After helium insufflation, collagen type IA1 expression showed a 1.1-fold increase.Conclusions The observed gas-related influence on collagen synthesis might give evidence of a potential effect of laparoscopy on intra-abdominal wound healing.
