Duodenal graft complications requiring duodenectomy after pancreas and pancreas-kidney transplantation

Abstract

Duodenal graft complications are poorly reported complications of pancreas transplantation that can result in graft loss. Excluding patients with early graft failure, after a median follow-up period of 126 months (range 23-198) duodenectomy was required in 14 of 312 pancreas transplants (4.5%). All patients were insulin-independent at the time of diagnosis. Reasons for duodenectomy included delayed duodenal graft perforation (n = 10, 71.5%) and refractory duodenal graft bleeding (n = 4, 28.5%). In patients with duodenal graft bleeding, a total duodenectomy was performed. In patients with duodenal graft perforation, preservation of a duodenal segment was possible in five patients but completion duodenectomy was necessary in one patient. After total duodenectomy, immediate enteric duct drainage was feasible in seven patients. In two patients, a pancreaticocutaneous fistula was created that was subsequently converted to enteric drainage in one patient. In the other patient, enteric fistulization occurred as a consequence of silent pressure perforation of the draining catheter on the ascending colon. After a mean follow-up period of 52 months (21-125), all patients were alive, well, and insulin-independent. An aggressive and timely surgical approach may permit graft rescue in patients with severe duodenal graft complications occurring after pancreas transplantation. Generalization of these results remains to be established.
