Intraoperatively malpositioned stent as a complication of common bile duct injury during laparoscopic cholecystectomy.

Injuries occurring during laparoscopic bile duct exploration in the course of laparoscopic cholecystectomy may represent threatening complications and lead to inappropriate management. We present a case of patient with biliary colic who underwent laparoscopic cholecystectomy. During the procedure, a common bile duct injury occurred, compelling conversion to open approach, and the patient was treated using a manually inserted biliary stent. She was referred with severe right upper quadrant pain six weeks after the surgery. Investigation with endoscopic retrograde cholangiopancreatography showed a malpositioned biliary stent with completely extra-biliary trajectory. This is thought to be the first description of a malpositioned common bile duct stent through the common biliary duct as a complication of the commonly performed surgical procedure of bile duct exploration.
