Common Bile Duct Stone Caused by Migrated Surgical Clip 10 Years after Laparoscopic Cholecystectomy / 대한췌담도학회지

Rarely, surgical clips can migrate into the biliary tract after laparoscopic cholecystectomy and work as a nidus for biliary stone formation. We report a case of the development of a common bile duct (CBD) stone induced by surgical clip in a 57-year-old man who underwent laparoscopic cholecystectomy 10 years ago. On computed tomography, a CBD stone with a metallic material was found, and endoscopic retrograde cholangiopancreatography (ERCP) revealed a CBD stone including a metallic clip. The stone was removed completely by ERCP, and the surgical clip was found along with the stone.
