Retroperitoneal pancreas transplantation with systemic-enteric drainage--case report.

Enteric drainage and intraperitoneal graft position is the preferred technique for pancreas transplantation at most transplant centers. The technique of retroperitoneal pancreas transplantation was first described by Boggi et al. [Transplantation,79 (2005), 1137]. In this case report, a modified model of retroperitoneal pancreas transplantation with systemic-enteric drainage is presented. A 48-yr-old patient underwent combined retroperitoneal pancreas and kidney transplantation because of type-I-diabetes, and diabetic nephropathy. At the time of transplantation, the patient had a body mass index of 31 and severe atherosclerosis of the iliac vessels. After mobilization of the colon and mesocolon ascendens, the vessels of the pancreas graft were anastomosed end-to-side to the aorta and to the inferior caval vein of the recipient. For exocrinous drainage, a side-to-side duodenojejunostomy was performed after bringing a jejunal loop through a window in the right colon mesentery. The graft was in a retroperitoneal position. The patient was insulin-independent after 48 h, the lipase and amylase levels were within the normal range. The first experience with retroperitoneal pancreas transplantation with systemic-enteric drainage showed that the technique was safe and had technical advantages when compared with the classic method.

Incisional hernia following liver transplantation: incidence and predisposing factors.

BACKGROUND: Patients after orthotopic liver transplantation (OLT) have a high risk of developing incisional hernia (IH). In the literature incidences between 5% and 17% are reported. PATIENTS AND METHODS: In 90 patients, who underwent OLT between October 1998 and December 2005, a retrospective analysis on the occurrence of IH was performed. Surgical access for OLT was a transversal upper laparotomy. Age, gender, primary disease, ICU stay, immunosuppressive regimen and two different closure techniques (running suture or single sutures in layers) were evaluated. RESULTS: In 73 patients (76.7%, group 2) healing of the incision was without problems, in 17 patients (23.3%, group 1), IH occurred. Total survival was similar between the groups (86.3% vs. 94.1%, n.s.). No significant differences between the groups concerning age, gender, body mass index, platelet count and duration of ICU stay were found. Also, the technique of abdominal closure had no impact on the development of IH. No IH was found in patients with hepatocellular carcinoma (n = 15), whereas end-stage liver cirrhosis (n = 75) was associated with development of IH (p = 0.064). Multivariate analysis revealed end-stage liver cirrhosis, Sirolimus, and MMF to be independent significant risk factors for IH after OLT. CONCLUSION: IH following OLT has to be regarded a frequent complication. While technique of abdominal closure seems to have no impact, primary diagnosis and kind of immunosuppressive regimen exerted a significant influence on the formation of IH.
