The efficacy of Kasai operation for biliary atresia: a single institutional experience.

To assess the efficacy of Kasai operation for biliary atresia, 60 cases during a 14-year period (1976 to 1989) at this institution were reviewed. Thirty-four (56.7%) underwent operation within 90 days of life, 11 (18.3%) between 90 and 120 days and 15 (25.0%) beyond 120 days. Fifty-six underwent hepaticoportojejunostomy and 4 underwent hepaticoportocholecystostomy. Follow-up was 1 to 14 years (mean, 7.2 years). The postoperative follow-up of these 60 patients was categorized into five groups: group A (16 patients, 26.7%) was characterized by survival greater than 3 years and without jaundice; group B (3 patients, 5.0%) was defined as survival greater than 3 years, but with jaundice; group C (11 patients, 18.3%) was defined by survival but follow-up less than 3 years, (this group was further divided into C1 [7 patients, 11.7%] if anicteric and C2 [4 patients, 6.7%] if icteric); group D (2 patients, 3.3%) was patients who underwent liver transplantation; and group E (28 patients, 46.7%) was the group of patients who died at time of review. Group A and group C1 were interpreted as success after Kasai operation; hence, the potential success rate in this series was 38.3% (23 patients). They were long-term survivers, and most of them performed normal activities appropriate for their ages. We conclude that approximately one third of patients with biliary atresia would benefit from or be cured by this operation, which should be the first attempt in the treatment of this disease entity.
