International St. Mary's Hospital offers dedicated Kasai Procedure with experienced pediatric surgeons, hepatologists, advanced diagnostic support, and specialized postoperative care. Established in 2014, the JCI accredited hospital is situated in Seoul, South Korea and has 808 beds supporting pediatric liver and biliary care.

Kasai Procedure may be recommended for infants diagnosed with biliary atresia, where progressive blockage of the bile ducts can cause bile accumulation and liver damage. During surgery, the affected bile duct tissue is removed and the intestine is connected to the liver surface to provide an alternative route for bile drainage. Early treatment is important because prolonged bile obstruction can lead to progressive liver injury. Follow-up care includes monitoring bilirubin levels, liver function, growth, nutrition, and signs of complications such as cholangitis.
