Common bile duct foreign body: an unusual case.

A 59-year-old woman had symptomatic gallbladder stones. A laparoscopic cholecystectomy was performed using absorbable clips. Eleven weeks later, recent pain in the right upper quadrant and interscapular resulted in an ERCP. This examination demonstrated two Absolok Plus clips migrated in the biliary tract. We question the use of those clips and discuss the migration mechanism.
