Total Duodenectomy with Enteric Duct Drainage: A Rescue Operation for Duodenal Complications Occurring after Pancreas Transplantation

摘要

Duodenal graft complications (DGC) occur frequently after pancreas transplantation but rarely cause graft loss. Graft pancreatectomy, however, may be required when DGC compromise recipient's safety. We herein report on two patients with otherwise untreatable DGC in whom the entire pancreas was salvaged by means of total duodenectomy with enteric drainage of both pancreatic ducts. The first patient developed recurrent episodes of enteric bleeding, requiring hospitalization and blood transfusions, starting 21 months after transplantation. The disease causing hemorrhage could not be defined, despite extensive investigations, but the donor duodenum was eventually identified as the site of bleeding. The second patient was referred to us with a duodenal stump leak, 5 months after transplantation. Two previous surgeries had failed to seal the leak, despite opening a diverting stoma above the duodenal graft. Thirty-nine and 16 months after total duodenectomy with dual duct drainage, respectively, both patients are insulin-independent and free from abdominal complaints. Magnetic resonance pancreatography shows normal ducts both basal and after intravenous injection of secretin. The two cases presented herein show that when DGC jeopardize pancreas function or recipient safety, total duodenectomy with enteric duct drainage may become an option.
