Kasai Procedure: Treatment and Results Explained
April 21, 2025

The ducts of the liver play a crucial role in producing bile, which must be drained into the intestine to aid in the digestion of food. In a situation where these ducts are blocked, the Kasai procedure is used to bypass them surgically and prevent any further liver damage. The treatment for biliary atresia in India is innovative and unique, yielding excellent results. The Kasai procedure is also known as Kasai portoenterostomy or hepatoportoenterostomy.
The Kasai Procedure (Hepatoportoenterostomy)
To conduct this procedure, surgeons must remove the damaged ducts outside the liver. The ducts are replaced by using a small part of the patient’s intestine where bile should drain. This part not only connects to the liver but also to the major portion of the intestine. The Kasai procedure forms a Y-shaped path from where bile flows from the liver and into the intestine.
Benefits of the Kasai Procedure
- Restore bile flow effectively.
- Ensure your baby receives essential nutrients.
- Eliminate jaundice symptoms.
- Support healthy growth and development in your baby.
Kasai Post-Procedure
After this procedure, the patient will need to remain in the hospital for approximately 1 to 2 weeks. The procedure conducted will heal during this period, and doctors will medicate the child so that there’s no excessive build-up of fluid.
Results of the Kasai Procedure
Both bile flow and liver function will be restored to normalcy in at least 1/3 of children undergoing this procedure. They may not need liver transplantation unlike the 2/3 who undergo the kasai procedure and do not have sufficient bile flow and liver function. Half this group will need to have liver transplantation after the Kasai procedure while the other half will need to have it at some later date.
Post-Operative Recovery of Kasai Procedure
The child will be taken to the recovery area after the Kasai procedure. Here, the child will be taken to the paediatric floor and will remain there for a few days. Once the child demonstrates that they have been eating well, are pain-free, and do not have a fever, they will be sent home.
Is it Necessary for the Child to be Seen by a Surgeon After the Kasai Procedure?
Yes. About two weeks after the child is discharged, a nurse from the hospital will contact you to inquire about their health. The child will need to be met by the gastroenterologist and surgeon soon.
