Congenital hepatic duct obstruction with perforate diaphragms.

A patient had obstruction of the right and left hepatic ducts secondary to perforate diaphragms at the junction with the common hepatic duct. Transhepatic cholangiograms of both the right and left lobes were required to define the presence of diaphragms at the junctions of right, left, and common hepatic ducts. Excision of the diaphragms relieved the obstruction. A distinction should be made between congenital nonobstructive and congenital obstructive cystic dilation of intrahepatic biliary radicals.

Acalculous clonorchiasis obstructing the common 3ile duct: a case report and review of the literature.

Clonorchis sinensis has a minor incidence in Western countries and most commonly manifests as cholangiohepatitis with secondary bacterial infection. This parasite rarely obstructs the common bile duct without associated biliary stricture, stones or tumor. This paper documents the fourth reported case of acalculous C, sinensis biliary tract obstruction and reviews the world literature.
