Summary
Biliary atresia (BA) affects 1 in 17,800 Swiss births. Early Kasai portoenterostomy improves survival, but overall outcomes for BA patients in Switzerland are favorable. Further improvements in surgical timing are needed.
Area of Science:
- Pediatric Surgery
- Hepatology
- Epidemiology
Background:
- Biliary atresia (BA) is a rare neonatal liver disease requiring timely intervention.
- Understanding the epidemiology and outcomes of BA is crucial for improving patient care.
Purpose of the Study:
- To investigate the epidemiology of BA in Switzerland.
- To determine patient outcomes following diagnosis and treatment.
- To identify prognostic factors influencing survival.
Main Methods:
- Retrospective analysis of all BA patients born in Switzerland (1994-2004).
- Kaplan-Meier method for survival rates and log rank test for prognostic factors.
- Median follow-up of 58 months.
Main Results:
- BA incidence was 1 in 17,800 live births, with no significant variations.
- 4-year survival with native liver after Kasai portoenterostomy (PE) was 37.4%.
- 4-year overall survival was 91.7%; earlier PE (before 46 days) significantly improved native liver survival (75%).
Conclusions:
- Overall survival for BA in Switzerland is favorable compared to international standards.
- Optimizing the timing of Kasai PE is essential to reduce the need for liver transplantation (LT).
- Liver transplantation outcomes were excellent for all recipients.
