Hepatic portoenterostomy for congenital biliary atresia - method of dissection of porta hepatis, evaluation of revision, re-boring and supplementary operations.

A few guidelines for surgical dissection at the porta hepatis in hepatic portoenterostomy for congenital biliary atresia as evolved from our experiences on 52 cases are suggested. Indication for revision is also shown. Supplementary procedures in case of complications, such as ascending cholangitis and the onset of portal hypertension, are also described. An early primary operation as well as a positive revision and supplementary procedures for ascending cholangitis and oesophageal varices have resulted in an improvement of the therapeutic results.
