Post-Kasai Procedure (Biliary Atresia)
What is Post-Kasai Procedure (Biliary Atresia)?
Biliary atresia is a rare liver condition that affects newborns. The bile ducts that carry bile from the liver to the intestine are blocked or absent. Without treatment, bile builds up in the liver and causes serious damage.
The Kasai procedure, also called hepatic portoenterostomy, is a surgery that creates a new path for bile to drain. Surgeons connect the liver directly to the small intestine. This surgery is usually done in the first 2 to 3 months of life. The earlier it happens, the better the results tend to be.
After the Kasai procedure, monitoring liver function is critical. Blood tests help doctors see if bile is draining properly. Regular testing can catch problems early and guide decisions about future care. Some children thrive for years after surgery, while others may eventually need a liver transplant.
Symptoms
- Yellowing of the skin and eyes, called jaundice
- Dark urine that looks like tea or cola
- Pale or clay-colored stools
- Swollen or firm belly due to liver enlargement
- Poor weight gain or failure to thrive
- Irritability and fussiness
- Itchy skin from bile buildup
- Bleeding or bruising easily
After the Kasai procedure, some symptoms may improve if bile drainage is successful. However, liver problems can develop over time even when surgery goes well. Regular monitoring helps catch changes before they become serious.

Causes and risk factors
Biliary atresia happens during fetal development or shortly after birth. The exact cause is not fully understood. Researchers believe it may involve a combination of genetic factors, immune system problems, and viral infections. It is not inherited from parents in most cases. The condition affects about 1 in 10,000 to 15,000 babies.
The Kasai procedure is needed because biliary atresia blocks bile flow completely. Without surgery, the liver becomes damaged from bile buildup. Risk factors for poor outcomes after surgery include late diagnosis, severe liver damage before surgery, and ongoing inflammation. Some babies respond better to the surgery than others. Close monitoring after the procedure helps doctors adjust care based on how well bile is draining.
How it's diagnosed
Biliary atresia is diagnosed in infancy through a combination of physical exams, imaging tests, and liver biopsies. Blood tests show elevated bilirubin levels, which indicate bile is not flowing properly. After the Kasai procedure, regular blood testing becomes essential to monitor surgical success.
Total bilirubin levels are checked frequently after surgery. Declining bilirubin means bile is draining as it should. Persistent or rising bilirubin suggests the surgery is not working well enough. Rite Aid offers total bilirubin testing at Quest Diagnostics locations nationwide. Regular monitoring helps families and doctors track liver health and make informed decisions about next steps, including the possible need for liver transplant.
Treatment options
- Medications called ursodeoxycholic acid to improve bile flow and protect the liver
- Fat-soluble vitamin supplements, including vitamins A, D, E, and K
- High-calorie formula or special nutrition to support growth
- Antibiotics to prevent infections in the bile ducts
- Management of itching with medications like cholestyramine
- Regular blood tests to monitor liver function and bilirubin levels
- Preventive care for complications like portal hypertension or bleeding
- Liver transplant if the Kasai procedure fails or liver damage progresses

Frequently asked questions
The Kasai procedure is a surgery for babies with biliary atresia, a condition where bile ducts are blocked. Surgeons create a new path for bile to drain from the liver to the intestine. Without this surgery, bile builds up and causes severe liver damage. The procedure is most successful when done in the first 2 to 3 months of life.
Success is measured by how well bile is draining after surgery. Blood tests for total bilirubin are the main way to track this. If bilirubin levels drop, bile is flowing properly. If levels stay high or rise, the surgery may not be working well enough. Regular monitoring with your doctor is essential.
After surgery, symptoms may improve if bile drains well. However, jaundice, dark urine, pale stools, and poor growth can return if problems develop. Itchy skin, a swollen belly, and easy bruising are signs of ongoing liver issues. Contact your doctor right away if symptoms worsen or return.
In the first few months after surgery, blood tests are often done weekly or monthly. As your child stabilizes, testing may happen every few months. Your doctor will set a schedule based on how well bile is draining and your child's overall liver health. Consistent monitoring helps catch problems early.
Total bilirubin measures how much bile pigment is in the blood. High levels mean bile is not draining properly and the liver is struggling. After the Kasai procedure, declining bilirubin is a good sign. Persistent high levels may mean the surgery is not working and a liver transplant might be needed.
Some children do very well after the Kasai procedure and live for many years without a transplant. Others may need a liver transplant as they grow. Outcomes depend on how early surgery was done, how well bile drains, and individual factors. Regular monitoring and good medical care improve long-term health.
If bile drainage does not improve after surgery, liver damage will continue. Signs of failure include ongoing jaundice, rising bilirubin, and poor growth. In these cases, a liver transplant is the next step. Transplants have high success rates and can give children a chance at a healthy life.
Nutrition is key. Babies often need special high-calorie formulas and fat-soluble vitamin supplements. Preventing infections is also important, so good hygiene and avoiding sick contacts help. Your medical team will guide you on medications and feeding plans. Regular follow-up and blood tests are part of daily life.
The exact cause of biliary atresia is unknown. It likely involves genetic and immune factors, possibly triggered by a virus. It is not inherited in most cases and cannot be prevented. Early diagnosis and surgery are the best ways to protect the liver and improve outcomes.
Rite Aid offers total bilirubin testing through Quest Diagnostics, with about 2,000 locations nationwide. Regular testing helps track how well bile is draining after the Kasai procedure. Your doctor can order tests as part of routine monitoring. Consistent testing is one of the most important ways to watch liver health.
