A long-term experience with biliary atresia. Reassessment of prognostic factors.
Thirty-four infants with biliary atresia were primarily treated at our institution between 1974 and 1987. The mean age at diagnosis was 8.8 weeks. The Kasai portoenterostomy was used in 11 patients (32%) and the Sawaguchi modification in 23 infants (68%). Overall survival was 47% (16/34), with a mean follow-up of 45 months. Fifteen survivors (94%) are jaundice free, with two having undergone liver transplantation. Survival was not influenced by earlier age at operation, size of ductal remnants, or the use of an external biliary vent. Good bile flow was predictive of a favorable outcome. The incidence of cholangitis was increased in the Kasai (87%) versus the Sawaguchi groups (45%) (p less than 0.05), but 1-year survival rates were similar (55% vs 64%). The authors conclude that portoenterostomy offers a reasonable chance for success and should be the initial procedure for biliary atresia.
