Retroperitoneal biloma secondary to operative common bile duct injury

Encapsulated collections of bile ("biloma") may be a sequela of liver trauma, operative injury or disease. Such collections may be intrahepatic or extrahepatic and usually in the supramesocolic compartment of the abdomen. This is a report of a retroperitoneal biloma, an entity that has been reported only twice to date but this is the first secondary to an operative common bile duct lesion. Evacuation of the biloma and reconstruction of the associated biliary stricture were successfully carried out. The patient remains symptom free with normal clinical and laboratory data more than 14 months after surgery.
