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.
