Core Tip

Core tip: Previous study showed that more than 90% of children with biliary atresia (BA) surviving with native livers have clinical and laboratory evidence of chronic liver disease (CLD). In the present cohort, we found that 71% of patients with BA living with native livers had no clinical complications of CLD and 90% had normal liver synthetic function, only 2% had ideal medical outcome. Common medical complications encountered were cholangitis, portal hypertension and bleeding oesophageal varices. Portal hypertension and bleeding oesophageal varices were seen in 12% and 6% of children younger than 5 years of age. Medical surveillance in children with BA after Kasai surgery for medical complications should start even before 5 years of age.
