An uncommon cause of isolated common bile duct injury, a case report.

Abstract

Traumatic section of the common bile duct is an extremely rare phenomenon, especially when isolated. Usually, it occurs following biliary surgery particularly laparoscopic assisted surgery. This lesion is often associated with one or more lesions of neighboring organs. Mauritanie Médicale Janvier 2020 ; 3, Vol1 : 075 078 Page 75 We report a case of isolated section of the common bile duct following an abdominal trauma in a 5‑year‑old girl in the pediatric surgery department at the mother and child hospital in Nouakchott. Radiological exploration was inconclusive. Surgical exploration in front of the acute abdominal presentation revealed generalized peritonitis of biliary origin due to a lower bile duct wound. Extensive peritoneal lavage was performed in emergency as well as an external biliary diversion which was followed a month later by a procedure connecting the biliary duct system to the upper gastrointestinal tract. According to the literature the most serious complication of the common bile duct section is biliary peritonitis, its early postoperative morbidity is about 20 to 30% and its mortality varies from 0 to 2%. The clinical presentation and treatment of an isolated traumatic section of the common bile duct must be known in order to reduce morbidity and mortality. Its management must be multidisciplinary involving a pediatric surgeon, a radiologist and an anaesthesiologist
