Common bile duct obstruction palliated with common bile duct re-implantation (choledochoduodenostomy) in a cat.

A cat was presented with complete biliary obstruction at the level of the distal common bile duct (CBD), with loss of normal architecture. The area was excised and submitted for histopathology. Concurrent cholecystitis and gall bladder necrosis necessitated cholecystectomy. The proximal CBD was preserved and re-implanted adjacent to the original duodenal papilla. The cat recovered and remained asymptomatic for 6 months. At clinical relapse a carcinoma of suspected biliary origin was confirmed, and the cat was euthanized. In situations in which the CBD lumen cannot be re-established, the pathology is limited to the distal CBD, and the gall bladder is not available for cholecystoenterostomy, CBD re-implantation may be an option to salvage and retain a functional biliary tree.
