Outcome of living donor liver transplantation for post‐Kasai biliary atresia in adults

Previous reports described the effectiveness of living donor liver transplantation (LDLT) for post‐Kasai biliary atresia (BA) in the pediatric population. Information on the outcome of LDLT in patients that have reached adulthood after the Kasai procedure, however, is limited. A recent report postulated a poorer long‐term outcome of LDLT in these adults. We reviewed our experience to evaluate the validity of this hypothesis. Between January 1996 and October 2006, 385 LDLTs were performed at our institution. There were 80 post‐Kasai BA cases in the series; 60 (75%) were pediatric, and 20 (25%) were adults. There were no ABO blood type–incompatible cases. None were complicated with severe hepatopulmonary syndrome, portopulmonary hypertension, or hepatocellular carcinoma. The 5‐year overall survival rates were 90% for the adults and 90% for the children (P > 0.99). The median follow‐up period was 7 years in the adults and 11 years in the children. There was no donor mortality. The outcome of LDLT in adult post‐Kasai BA patients in the present series was satisfactory; that is, adult and pediatric patient survival rates were not different. This finding suggests that for post‐Kasai BA patients without serious comorbidity at the time of transplantation, LDLT can be performed safely in all age groups.
