Initial response to portoenterostomy determines long-term outcome in patients with biliary atresia

Purpose: The aim of this study was to assess the efficacy of portoenterosto my in biliary atresia and determine factors that predict outcomes. Methods: The outcomes after portoenterostomy for biliary atresia from 1976 to 1996 were graded into 3 defined groups: G (good, jaundice free); I (inte rmediate, progressive liver disease with liver transplant if needed after 3 years of age); P (poor, liver transplant or death at less than 3 years of age). Results: Twenty-seven of 49 children (55%) who underwent portoenterostomy r esponded, Of these, 13 (26%) were jaundice free (G). Of 14 children (28%) i n 1, 6 underwent liver transplant after 3 years of age. Of 22 children (44. 8%) in P, 14 (28%) died before 3 years and 8 underwent liver transplant bef ore 3 years. Thus, 42% of the children in this series are surviving with na tive liver. Age at operation in P was significantly different compared with G. Preoperative values of bilirubin and alanine transaminase were comparab le in the 3 groups. Postoperative values of bilirubin and alanine transamin ase were lower in G and I compared with P. Complications were significantly lower in group G. Conclusions: Portoenterostomy alone in biliary atresia is beneficial in 40% of cases. Factors associated with the outcome include age at operation, po stoperative cholangitis, and change in values of bilirubin and alanine tran saminase. A classification based on decline of bilirubin and enzyme levels 3 months after portoenterostomy is proposed to predict the long-term outcom e of an individual case of biliary atresia. It is particularly relevant in the intermediate group in which timing of referral may preclude or compromi se liver transplant. Copyright (C) 2000 by W.B. Saunders Company.
