The Establishment of the Animal Model Imitation the Congenital BiNary Tract Dilatation-The Practice and Result of the P-Ch-ostomy on Dogs

It is well known that most of the children with CB D(the congenital biliary tract dilatation)have APB DU(the abnormal pancreaticobiliary ductal union).More and more authors agree to that APB DU is the main cause of CBD.This paper discribed the model making of the P-Ch-ostomy(pancreatico-cholecystostomy)on 5 mongrel adult dogs.The reflux of pancreatic juice into the bile duct and the dilatation of common bile duct similar to the human anomalies occurred in all the dogs.So this animal model is receommended to be used in studying various diseases of the biliary tract and pancreas which are considered to be caused by the APBDU.
