Summary
Performing a Kasai portoenterostomy for biliary atresia in infants over 75 days old shows a high success rate. This late intervention for biliary atresia is a viable option, offering good outcomes.
Area of Science:
- Pediatric Surgery
- Hepatology
- Neonatal Care
Background:
- Extrahepatic biliary atresia requires timely Kasai portoenterostomy, ideally within 10-12 weeks of life.
- Optimal management for delayed biliary atresia presentation is debated.
- This study evaluates the efficacy of late Kasai portoenterostomy.
Purpose of the Study:
- To determine the success rate of Kasai portoenterostomy in infants presenting later than 12 weeks.
- To assess long-term outcomes, including liver transplantation and survival, after late Kasai portoenterostomy.
- To analyze the relationship between age at surgery and patient outcomes.
Main Methods:
- Retrospective review of 31 biliary atresia patients undergoing Kasai portoenterostomy (1986-1999).
- Analysis of surgical success (total serum bilirubin ≤ 2 mg/dL) based on age at procedure.
- Evaluation of liver transplant rates and patient survival.
Main Results:
- A higher success rate (83%) was observed in patients aged 76 days or older compared to those aged 0-75 days (52%).
- Liver transplantation was required in 45% of patients.
- Overall survival was 74%, with 39% alive without transplantation.
Conclusions:
- Kasai portoenterostomy is a viable treatment option for biliary atresia even when performed after 75 days of age.
- Delayed Kasai portoenterostomy does not appear to be contraindicated.
- The study supports considering late Kasai portoenterostomy for eligible patients.
