腹腔鏡下胆嚢摘出術術後, 迷入したクリップを核として総胆管結石を形成 した1例

The patient was a 71-year-old who had received laparoscopic cholecystectomy for cholecystitis due to cholecystolithiasis on November, 1993. He had spent with no complaint after operation. But he consulted our department with epigastralgia and jaundice on February 1997. Abdominal CT and DIC revealed one calculus-like shadowy defect in the common bile duct and demonstrated metallic density at the defect in the lower part of the common bile duct. We diagnosed postoperative bile duct stone by aberrant surgical clip after laparoscopic cholecystectomy. We performed endoscopic balloon dilation of duodenal papilla and removed the common bile duct stone using basket forceps. In Japan, eight cases of migration of clip after laparoscopic cholecystectomy into bile duct have been reported, including our case. In accordance with the prevalence of laparoscopic cholecystectomy, such cases will increase and it was suggested that we must observe the course over a long period of time.
