Retrograde Pancreatic Duct Stent Migration into the Biliary Tract Presenting as a Rare Early Complication of Pancreaticoduodenectomy (Whipple Procedure).

BACKGROUND Pancreaticoduodenectomy (Whipple procedure) is an established surgical procedure for the treatment of carcinoma of the head of the pancreas. Modifications to this procedure include gastropancreaticoduodenectomy, which includes the removal of parts of the pancreas, duodenum, and stomach. Complications of surgery include fistula formation, failure of the anastomosis, and leak of pancreatic enzymes, which can be reduced by stenting the pancreatic duct.
