Increased age at surgery had a progressive and sustained deleterious effect on the results of the Kasai operation until adolescence. These findings indicate a rational basis for biliary atresia screening to reduce the need for liver transplantations in infancy and childhood.

Since the sequential treatment of Kasai operation with or without liver transplantation became available, the overall prognosis of biliary atresia remains unclear. This study examined the prognostic factors from diagnosis. All patients with biliary atresia living in France and born in the years 1986 to 1996 were reviewed. Actuarial survival rates were calculated for survival with native liver, survival after liver transplantation, and overall survival. Potential prognostic factors were analyzed using the logrank test and the Cox model. A total of 472 patients were identified. Ten-year overall survival was 68%. Independent prognostic factors for overall survival were (S ‫؍‬ 10-year rates) performance of Kasai operation (performed: S ‫؍‬ 69%; not performed: S ‫؍‬ 50%), age at Kasai operation (I45 days: S ‫؍‬ 80%; G45

To define the long-term prognosis of children undergoing the Kasai operation for biliary atresia, a retrospective study was undertaken comprising 271 patients operated between 1968 and 1983. Twenty years after surgery, 63 (23%) were alive with their native liver. Serum bilirubin was normal in 21 of these patients, 12 also had normal serum aminotransferase and ␥-glutamyltransferase activities, all but 2 had signs of cirrhosis, 44 had signs of portal hypertension, 19 had late bacterial cholangitis, and 6 had gallstones. Seven female patients gave birth to 9 children, and 3 male patients fathered 6 children. After age 20, 2 patients died of liver failure and 14 underwent or are awaiting liver transplantation. Twenty-year survival with native liver was significantly better in children with biliary atresia restricted to the hepatic ducts or with cysts at the porta hepatis. In conclusion, in the long term, less than 18% of infants with biliary atresia who are treated with corrective surgery may avoid liver transplantation, but even these patients require assiduous lifelong care.
