Surgical limitation for biliary atresia: indication for liver transplantation.

Of 245 patients undergoing corrective operations for biliary atresia, jaundice was cleared in 113. In January 1988, 84 of them were living and free of jaundice and the other 19 were alive with jaundice. A vast majority of long-term survivors showed normal growth and development, and were leading normal lives for their respective ages. Portal hypertension, a common late complication, improved spontaneously or after sclerotherapy in jaundice-free patients. Therefore, liver transplantation is not recommended for jaundice-free patients even with esophageal varices. Patients with persistent severe jaundice (serum bilirubin over 10 mg/dL) and those with moderate jaundice (serum bilirubin 5 to 10 mg/dL) and severe esophageal varices require liver transplantation. Patients with moderate jaundice having no or slight varices should be carefully followed. When varices become worse or serum bilirubin rises, liver transplantation is indicated. Patients with mild jaundice (serum bilirubin lower than 5 mg/dL) have a possibility of improvement in their condition before the age of 15 years, and are not recommended for liver transplantation. The high value of the lowest postoperative bilirubin level suggests the necessity of liver transplantation in early childhood. Liver transplantation as the primary treatment for biliary atresia may be indicated only for patients over 120 days of age with an enlarged and hard liver.
