Abstract

Choledocholithiasis caused by a foreign body is rare. The most common type of foreign body in the common bile duct is a residual object from previous surgery such as a metal clip or suture material. Foreign body may enter the biliary system after choledochointestinal anastomosis or endoscopic sphincterotomy. Rarely, penetrating missile fragment or gunshot shrapnel account for another type of foreign body. We experienced a case of common bile duct (CBD) stone caused by foreign meterial in 75-years-old women who had a plant foreign body in the common bile duct. She had no past history of abdominal surgery or penetrating trauma. The foreign body and stone were successfully extracted with Dormia basket after the endoscopic sphincterotomy.
