E. Handharyani et al., Extrahepatic bile duct malformation causing intrahepatic cholangiocellularproliferation with fibrosis in broiler chickens, AVIAN PATH, 30(1), 2001, pp. 63-65
Malformation of the extrahepatic biliary tracts was observed in six of 88 e
nlarged, firm and discoloured livers collected at a slaughterhouse. Histolo
gically, the six livers were characterized by diffuse cholangiocellular pro
liferation with fibrosis, extremely similar to the condition induced by bil
e duct ligation. These findings suggested that some cases of cholangiohepat
itis in chickens are caused by biliary malformations with bile stasis.
