Adenocarcinoma of the duodenum arising in a tubulo-villous adenoma.

Villous adenoma of the duodenum is rare and has a high prevalence of cancer. We report here an unusual case of a 73-year-old man who presented with a tumour on the second part of the duodenum with moderate dysplasia of a tubulo-villous adenoma at the biopsies. A segmental duodeno-jejunal resection was performed and the resection margins were negative.

Use of marginal donors for liver transplantation: a single-center experience within the Eurotransplant patient-driven allocation system.

Background: Due to the organ shortage, marginal donors are increasingly used in liver transplantation (OLT). These grafts may be safely used in less critical recipients but, the real influence of extended donor criteria (EDC) remains uncertain when graft-recipient matching is not applied. Our study analyzed the impact of EDC on initial graft function within the Eurotransplant patient-driven allocation system.

The suturing concept for laparoscopic mesh fixation in ventral and incisional hernia repair: Mid-term analysis of 400 cases.

Background: The authors describe a minimally invasive treatment of moderate to large incisional and ventral hernia defects using Parietex composite mesh.

Methods: All defects are closed laparoscopically or through a minilaparotomy using sutures, and the composite mesh is fixed intraperitonally using transabdominal fixation with nonabsorbable sutures to avoid the use of staple or tack fixation, which has been associated with various complications, including major loop adhesion and mesh migration. The midterm results for 400 patients are presented in terms of efficacy and safety.
