title: British paediatric surveillance unit study of biliary atresia: outcome at 13 years.
abstract: BACKGROUND
  Little information is available on contemporary, prospectively collected data on the long-term outcome of national cohorts of children with biliary atresia.
  
  
  OBJECTIVE
  This study aimed to describe the current outcome of a national cohort of children with biliary atresia.
  
  
  METHODS
  All 93 cases of biliary atresia in the United Kingdom and Ireland diagnosed between March 1993 and February 1995 were followed up prospectively.
  
  
  RESULTS
  A total of 91 children underwent Kasai portoenterostomy in 15 individual centres. Only 2 centres treated more than 5 children annually. Median age at last follow-up was 12 years (range 0.25-14). Fifteen children (16%) have died: 10 after unsuccessful portoenterostomy, 1 of sepsis after successful portoenterostomy, and 4 after liver transplantation. Forty-two (45%) underwent liver transplantation at a median age of 1 year (range 0.5-9), with 90% survival. All 41 children with failed portoenterostomy (and 2 without portoenterostomy) died or underwent liver transplantation at a median age of 0.8 years (range 0.25-6.5). When the portoenterostomy was successful, 40 of 50 patients (80%) are alive without liver transplantation. The 13-year actuarial survival without liver transplantation is 43.8% overall and is better in children treated at centres that treat more than 5 cases yearly (54% vs 27.3%, P = 0.005).
  
  
  CONCLUSIONS
  If the portoenterostomy is successful, then few children with biliary atresia will need transplantation before adolescence. Children with biliary atresia should be treated in experienced centres to maximize the chance of successful surgery.
