Abstract
One of the fundamental innovations of pediatric surgery is hepatic portoenterostomy for biliary atresia, widely known as the Kasai procedure for its originator, Morio Kasai (1922-2008), of Sendai, Japan. It was the first effective operation for the “uncorrectable” form of biliary atresia, where death within months from biliary cirrhosis was certain. His radical premise was that microscopic ductules present in the fibrous tissue of the porta hepatis, when transected, drained enough bile to relieve cholestatic jaundice. His first operations from 1955-1961 had a jaundice-free survival rate of only 8 percent, but the cures were durable. By 1982-1986 survival reached 55 percent.Adoption of his procedure in the West came slowly. The original operation in 1955 was reported in the Japanese literature in 1959, but the first English language communication came in 1968. Surgeons disbelieved his results. Scientific chauvinism held that advances in pediatric surgery came from America and Europe; Japan had little to add.Surgeons visited Sendai to learn from Kasai, notably John Lilly and R. Peter Altman, then of Washington, DC, Jacques Valayer in Paris, and Edward Howard in London. At first, mortality rates in their hands was high. As expertise developed in the West with the technically demanding operation, mortality fell and approached those reported by Kasai. Successes in America, France, and England proved Kasai’s operation as effective and one of signal achievements in pediatric surgery.
