Introduction: Reports of liver transplantation (LT) after Kasai portoenterostomy (KPE) in adult patients with biliary atresia are scarce. The aim of this study was to evaluate the outcomes and investigate the risk factors of LT after KPE in both pediatric and adult patients.
Methods: We retrospectively reviewed a prospective database of patients with biliary atresia who underwent LT after KPE. Eighty-nine consecutive patients were included, and risk factors for in-hospital mortality after LT were assessed.
Results: The median age of the patients was 2 y (range, 0-45 y). Forty-six patients (51.7%) had a history of upper abdominal surgery after KPE. The in-hospital mortality rate was 5.6% (5 patients). Of these, 80% of patients with mortality were aged ≥17 y, and all patients with mortality had a history of two or more upper abdominal surgeries. In the univariate and receiver operating characteristic curve analyses, age ≥17 y and the number of previous upper abdominal surgeries ≥2 were identified as possible risk factors.
Conclusions: Our study suggests that older age and multiple previous upper abdominal surgeries are important risk factors for mortality after LT following KPE. We believe that these findings will serve as indications for safe LT in future patients.
