Migrated endoclip and stone formation after cholecystectomy: a case treated by endoscopic sphincterotomy.

Endoclip migration into the common bile duct following laparoscopic cholecystectomy (LC) is an extremely rare complication. Migrated endoclip into the common bile duct can cause obstruction, serve as a nidus for stone formation, and cause cholangitis. We report a case of cholangitis due to a migrated endoclip and consequent choledocholithiasis 6 years after LC, which was successfully treated by endoscopic extraction.
