Therapeutic biliary endoscopy has been widely used to manage bile duct stones prior to, during, or after laparoscopic cholecystectomy and to treat complications of the procedure [1]. Since laparoscopic cholecystectomy came into widespread use, there have been reports on migration of the clips used to close the cystic duct or occlude the cystic artery [2] [3]. There have been cases of direct migration through the papilla causing cholangitis, and of the development of choledocholithiasis [4] [5] [6]. The present report describes a case of choledocholithiasis caused by the migration of two clips, probably from the cystic duct, which served as a nucleus for the formation of the stone.
