Hepatic Portoenterostomy in Infants

Medically reviewed by Last updated on Jun 5, 2024.

What do I need to know about hepatic portoenterostomy?

Hepatic portoenterostomy, or Kasai procedure, is surgery to treat biliary atresia. Biliary atresia is a blockage of the bile ducts (tubes) that carry bile from the liver to the gallbladder. Bile is a liquid made by the liver that helps with digestion.

How do I prepare my baby for surgery?

What will happen during my baby's surgery?

General anesthesia will keep your baby asleep and free from pain during surgery. Your baby's surgeon will make an incision on the upper right side of your baby's abdomen. He or she will remove the blocked bile ducts. Your baby's liver will be connected to his or her small intestine. This creates a new duct to drain bile from your baby's liver. Your baby's surgeon may inject a dye to check for any leaks in the new duct. The incision will be closed with stitches or staples. A bandage will be placed over the incision.

What are the risks of surgery?

Your baby may bleed more than expected or get an infection. Pressure or fluid may build up in his or her blood vessels or abdomen. Your baby may have an increased risk for poor nutrition and growth. His or her liver may scar or stop working properly. The new duct may stop working and your baby may need another surgery.
