Abstract Long-term results after surgery for biliary atresia (BA) in 48 patients, ranging in age from 10 to 33 years, were examined. There were 19 males and 29 females. Twelve had correctable type BA and 36 had the noncorrectable type. Forty-one cases had no jaundice; seven did. Thirty-seven of the 48 cases were leading normal lives. Among them, six cases were enjoying their lives after overcoming sequelae, such as portal hypertension. The main morbidities of the remaining 11 long-term survivors were jaundice and portal hypertension. The growth of most cases were comparable to those of the normal Japanese population. The data of liver function tests were variable and disclosed a moderate degree of abnormality in patients mainly complicated by cholangitis. Eleven cases, including six jaundice cases, required treatment for esophageal varices and/or hypersplenism. In conclusion, the cured states of most cases without jaundice are satisfactory and these former patienta have achieved a favorable quality of life. Early operations are essential to obtain good short-term results as well as good long-term results.
