Outcomes for Canadian children with biliary atresia were similar across two eras, with overall 4-year survival at 81%. Early Kasai operation significantly improves native liver survival, highlighting the need for timely diagnosis and intervention in pediatric liver disease.

Area of Science:

  • Pediatric Hepatology
  • Gastroenterology
  • Surgical Outcomes

Background:

  • Biliary atresia is a severe neonatal liver disease requiring timely intervention.
  • Liver transplantation is a critical treatment option for end-stage biliary atresia.

Purpose of the Study:

  • To evaluate the long-term outcomes of Canadian children diagnosed with biliary atresia.
  • To compare outcomes between two distinct treatment eras, considering the advent of liver transplantation.

Main Methods:

  • Retrospective review of health records for infants diagnosed with biliary atresia between 1985-2002.
  • Analysis of patient survival, native liver survival, and liver transplantation rates.

Main Results:

  • The 4-year survival rate was 81%, with no significant difference between the two study eras (ERA I: 74%, ERA II: 82%).

  • Kasai operation performed at or before 30 days of age resulted in significantly higher 4-year native liver survival (49%) compared to later interventions (36-23%).
  • The 4-year liver transplantation survival rate was 82%, with similar outcomes across both eras.

    • Conclusions:

    • Outcomes for biliary atresia in Canadian children are comparable to international standards.
    • Late referral for diagnosis and treatment remains a significant challenge, necessitating improved policies for early detection.
    • While liver transplantation has improved survival, optimizing the timing of the Kasai operation is crucial for preserving native liver function.
