Cholangigrams in 14 cases with biliary atresia were evaluated. The intrahepatic bile ducts were visualized by retrograde cholangiography (operative or postoperative) in 6 cases of type I atresia (atresia at the common bile duct) and by percutaneous transhepatic cholangiography in 8 cases of type III atresia (atresia at the porta hepatis) and in one case of type I atresia. The intrahepatic bile ducts were abnormal in all cases. Repeat postoperative cholangiography showed that the intrahepatic bile dusts had been degenerated progressively in the cases with poor operative result. Postoperative percutaneous transhepatic cholangiography showed that the intrahepatic bile ducts had become almost normal in certain cases with satisfactory result.
