Diagnosis and nonsurgical management of bile leak complicated by biloma after blunt liver injury: report of two cases.

We report on two patients with biliary tract injury and associated biloma following blunt abdominal trauma. Both patients underwent emergency surgery because of hemodynamic instability and bloody peritoneal aspiration. Computed tomography in the postoperative days showed severe hepatic parenchymal injury and the presence of hypodense collections with intraparenchymal and subcapsular extension, suggestive for biloma, but otherwise failed to demonstrate the exact location of the bile duct injury. One of them underwent temporary percutaneous drainage. Bile duct injury was well demonstrated on endoscopic retrograde cholangiography (ERCP) and treated by endobiliary stent placement. This report advocates the use of ERCP and endobiliary stenting in the management of biliary injury resulting from liver trauma.
