Clip Choledocholithiasis after Laparoscopic Cholecystectomy

Table of Contents

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.

The patient was a 52-year-old woman who had undergone laparoscopic cholecystectomy for acute cholecystitis 7 months previously. She presented with a history of a recent onset of pain in the right upper quadrant, radiating to the back. Laboratory values showed elevated bilirubin (2.16 mg/dl), alkaline phosphatase (756 U/l), and alanine aminotransferase (200 U/l). Ultrasonography showed a dilated bile duct (9 mm), but did not reveal any stones.

Endoscopic retrograde cholangiopancreatography (ERCP) was carried out. A previous radiograph had shown two clips in the right upper quadrant (Figure [2 a]). Once the bile duct had been cannulated, a defect was seen in the distal bile duct, which corresponded to a stone with clips inside it. Papillotomy was carried out, and the stone was extracted. There were no other stones, and drainage was good. Two clips were found in the stone after removal (Figure [1]). The final radiograph showed no clips in the right upper quadrant (Figure [2 b]). The patient’s post-ERCP course was uneventful and she was discharged.
