AbstractStrictures of the intrahepatic bile ducts are rare. Frequently, the condition passes unrecognized by both the internist and the surgeon, and is too often discovered only at autopsy. The strictures are related either to an inflammatory process, which is rare, or to a tumor which is more common. Benign or malignant stenosis may involve an intraparenchymatous hepatic duct or one of its segmental afferents. It results in proximal stasis, infection, lithiasis, and biliary cirrhosis. In fact, the prognosis and treatment of the lesion are dominated by the inflammatory or malignant origin of the stricture.
