His contributions to pediatric surgery have had a lasting impact on the treatment of this congenital condition.

Early Life and Education

Development of the Kasai Procedure

The Kasai procedure, also known as the hepatoportoenterostomy, was developed in the 1950s. This innovative surgical technique involves the removal of the atretic bile ducts and the creation of a new pathway for bile drainage from the liver to the intestine. The procedure is typically performed on infants diagnosed with biliary atresia, a condition where the bile ducts are blocked or absent, leading to liver damage.

Kasai's procedure significantly improved the prognosis for infants with biliary atresia, offering a chance for normal liver function and growth. Prior to this development, the condition was almost universally fatal.
