Technical factors that minimize the occurrence of early graft failure in pancreas transplantation.

Pancreatic transplantation is the only treatment for insulin‐dependent diabetes resulting in long‐term euglycemia without exogenous insulin. However, pancreatic transplantation has become debatable following the improvements in the results of islet transplantation and artificial pancreas. Therefore, surgeons who perform pancreas transplants require the best surgical technique that can minimize technical failure. We aimed to report our experiences with pancreatic transplantations. We transplanted 65 pancreatic grafts between 2015 and 2020. Except for one death due to hypoxic brain damage after surgery, no postoperative technical failure was observed. We usually perform duodeno‐duodenal anastomosis using the transperitoneal approach, with retrocolic placement of the graft pancreas. There was no leakage from the duodenum even after immunologic graft failure. To prevent venous thrombosis, which is the most common cause of technical failure, we used the inferior vena cava for anastomosis and added graft venoplasty with a patch of donor vena cava or aortic interposition graft to the bench procedure; subsequently, there were no cases of technical failure due to thrombosis post‐transplantation. Therefore, the 1‐year graft survival (insulin‐free) rate was more than 95%. The improving the surgical technique will maintain pancreatic transplantation as the best treatment for insulin‐dependent diabetes. [ABSTRACT FROM AUTHOR]
