[Closed injuries of the intrahepatic bile ducts--clinical presentation, diagnosis and treatment].

Two cases of blunt trauma of the intrahepatic bile ducts are described: one illustrates the difficulty to establish a diagnosis that is often delayed, the other emphasizes the usefulness of the peroperative cholangiography to precise the diagnosis and define the treatment. In the two cases a simple drainage either perihepatic or of the common bile duct resulted in complete healing of the biliary wound. When liver rupture and bleeding complicates a biliary injury, efficient packing allows to reoperate the patient under better conditions the next day. According to the extent and location of the biliary injury, simple drainage, direct suture, bilio-digestive anastomosis and even hepatectomy in rare cases will be indicated.
