title: Biliary web--a rare cause of extrahepatic biliary obstruction.
abstract: A case of an isolated mucosal web of the common hepatic duct is presented. Such extrahepatic biliary webs are extremely rare causes of biliary obstruction, likely congenital in nature, but presenting in later life due to the initial patency of these webs in allowing bile drainage from the liver. The relevant literature is reviewed; diagnostic and therapeutic aspects are discussed.
