Treatment of biliary atresia: a study of our operative results.

The operative results in 87 biliary atresia cases were investigated from the aspect of the histologic findings in the liver and the remnant of the extrahepatic bile ducts, and the details of the operative procedures. The degree of liver fibrosis, the liver cell changes, and the type of extrahepatic bile ducts are closely related to our operative results. Our operative results have been improving since 1977 due to the advancement of microsurgical techniques and a new type of operative procedure for prevention of ascending cholangitis. Twenty-five of 29 cases (86.2%) surgically corrected are alive, showing bile excretion, and are in a satisfactory general condition.
