Kasai Procedure
Pronunciation: kah-SAH-ee
Surgical procedure connecting the intestine directly to the liver to restore bile flow in biliary atresia.
Full Definition
The Kasai procedure, formally known as hepatoportoenterostomy, is the primary surgical treatment for biliary atresia, first described by Morio Kasai in 1959. The procedure involves removing the atretic bile ducts and creating a direct connection between the liver hilum and a Roux-en-Y jejunal loop to restore bile drainage. Success depends heavily on early timing, ideally performed before 60 days of age for optimal outcomes. The procedure can restore bile flow and delay the need for liver transplantation, though long-term complications including cholangitis and progressive liver disease remain common.
Usage
Usage note: Named after Japanese surgeon Morio Kasai; sometimes referred to simply as 'Kasai' in clinical notes.
