Abstract

This report describes extrahepatic bile duct obstruction in two ferrets, which were presented with anorexia, chronic weight loss and general weakness. Physical examination revealed lethargy, cachexia, dehydration, abdominal pain and icterus. Marked haematological, serum chemistry and urinalysis abnormalities included hyperbilirubinaemia (65·5 and 114·2 μmol/L), high concentrations of alanine transaminase (1327·53 and 2578·88 IU/L) and biluribinuria. Abdominal ultrasonography revealed thickening of the bile duct together with the gall bladder wall. The common bile duct was obviously distended. Choledochotomy revealed inspissated bile with fragile green gelatinous plugs that was removed to allow the bile to flow into the duodenum. Cytology and culture of the biliary tract contents were negative for bacteria. Laboratory analyses of biliary plugs showed presence of only protein substances, without detectable mineral composition. Histopathological examination of the liver showed diffuse steatosis and non-specific cholangiohepatitis in both cases.
