Bezoar-Related Pancreatitis in Enterically Drained Pancreas Transplant

Simultaneous kidney and pancreas transplantation is currently the treatment of choice for type 1 diabetes mellitus with end-stage renal disease. As a result of improvements in surgical techniques and the efficacy of immunosuppression, patient and graft survival rates have improved dramatically over the last two decades. Despite this, it remains a challenging surgical procedure with many potential complications and occasional controversies. Causes of pancreatitis after pancreas transplantation with enteric drainage are not well documented in the literature. We report a case of allograft pancreatitis from pancreatic duct outflow obstruction due to formation of a bezoar in a diverticulized transplant duodeno-jejunal anastomosis. To the best of our knowledge, this is the first case of allograft pancreatitis reported in the literature occurring from bezoar formation.
