Duodenoscrotal fistula secondary to retroperitoneal migration of an endoscopically placed plastic biliary stent.

Endoscopic placement of a biliary stent for management of neoplastic biliary stricture is generally safe and relieves cholestasis in approximately 80% of cases. Complications such as hemorrhage and cholangitis related to the endoscopic procedure are rare. Other complications, such as intestinal perforation related to erosion through the intestinal wall by the distal end of the stent or proximal or distal stent migration, are rare but frequently lead to life-threatening problems and occasionally death. A case of duodenal-scrotal fistula by means of the retroperitoneal space secondary to perforation of the duodenum by a plastic biliary stent is reported. To our knowledge, this is the first report of such a complication.
