Open sphincteroplasty for benign ampullary stricture after pancreas transplantation.

Ampullary and proximal pancreatic duct strictures are well known to result in recurrent episodes of pancreatitis in the native pancreas, which when benign in origin can often be treated with sphincteroplasty (open or endoscopic) and stenting in the native pancreas. However, recurrent episodes of pancreatitis in a transplanted pancreas allograft can have multiple potential etiologies, and if the diagnosis of pancreatic duct stricture is made, treatment with preservation of the pancreatic allograft can be challenging. This is the first case report to describe the open sphincteroplasty of a short benign ampullary stricture in a transplant pancreas allograft.
