Introduction Age at Kasai portoenterostomy (KPE) has been identified as a predictive factor for native-liver survival in patients with biliary atresia (BA). Outcomes of pediatric liver transplantation (LT) have improved over recent years. It has been proposed to consider primary LT as a treatment option for late-presenting BA infants instead of attempting KPE. We present our experience with patients older than 90 days undergoing KPE.

Mean age at KPE was 108 days (range: 90–133 days).
Results Postoperative jaundice clearance (bilirubin
