Liver transplantation for biliary atresia: a systematic review

Biliary atresia (BA) is an idiopathic neonatal cholangiopathy characterized by progressive inflammatory obliteration of the intrahepatic or extrahepatic bile ducts. Although the Kasai operation has dramatically improved the outcomes in children with BA, most patients with BA eventually require liver transplantation (LT) even after undergoing a successful Kasai procedure. The Japanese LT Society (JLTS) was established in 1980 to characterize and follow trends in patient characteristics and the graft survival among all liver transplant patients in Japan. The 1-, 5-, 10-, 15- and 20-year survival rates for the patients and grafts undergoing living donor LT were 91.6, 91.5, 87.1, 85.4 and 84.2 and 90.5, 90.4, 84.6, 82.0 and 79.9%, respectively. LDLT was able to be performed even in patients weighing less than 5 kg with early liver failure following a Kasai operation using a reduced left lateral segments. As LT has been revealed to increase the donor pool and decrease the waiting list mortality with an excellent long-term graft survival, early referral to a transplant center should be considered when at least one complication of cirrhosis occurs during its natural history, especially in adolescents.
