Novel surgical technique and efficacy analysis of donor pancreas preparation without vascular reconstruction in pancreas transplantation

OBJECTIVE: Because of the complicated blood supply and vascular structure of the pancreas, blood vessel reconstruction and reshaping are generally required during pancreas transplantation. We modified the vascular preparation procedure for the donor pancreas (i.e., no vascular reconstruction was performed) based on experiences in our department and in other domestic and international transplantation centers. METHODS: Twelve donor pancreas preparations without vascular reconstruction were performed. The patch (Carrel patch), celiac trunk, and superior mesenteric artery were preserved as arterial inflow channels for the donor pancreas. The common hepatic artery and the gastroduodenal artery were transected at a site 0.5 cm away from the bifurcation. The bifurcated portion was preserved for the donor liver. The stumps of the gastroduodenal artery and common hepatic artery were then ligated. The portal vein was transected in the middle of the hepatoduodenal ligament during separation of the liver and pancreas. The partial portal vein preserved with the pancreas was used as the outflow channel of the donor pancreas. RESULTS: The transplanted pancreas functioned well in the recipients, and no vascular complications were reported. CONCLUSION: The overall efficacy of pancreas transplantation without vascular reconstruction has been improved.
