Introduction

Biliary atresia is a condition that affects children, usually newborns, when the bile ducts outside the liver are damaged or completely absent. If left untreated, bile will accumulate in the liver and cause chronic damage.

We understand that as a parent, receiving a diagnosis for your child is frightening. However, with the right diagnosis and treatment, your child can make a full recovery. So, what are the signs and symptoms of biliary atresia, how is it diagnosed, and when is a liver transplant necessary? We will go over each of these questions in detail.

Biliary atresia is a condition characterized by the blockage or absence of the bile ducts outside the liver. Bile is a fluid that is produced by the liver and aids in the digestion of fats. It does so by turning fats into smaller components that can be absorbed by the intestine. The bile is produced by the liver and is then transported to the intestine through the bile ducts.

If the bile ducts are damaged or blocked, then the bile cannot be transported and will start to accumulate in the liver. This will cause inflammation and scarring of the liver which will be irreversible and will damage the liver permanently.

Think of bile ducts like small drainage pipes. If drainage pipes get blocked, fluid will build up. The same thing happens if bile ducts get blocked. Bile builds up and can eventually damage the liver.

Biliary atresia treatment requires early diagnosis and expert care. Learn about symptoms, diagnosis, liver transplant options, and treatment from Dr. Neerav Goyal, the best liver transplant surgeon in India.

Biliary atresia gets recognized in newborns and infants 6 months and under. It is a condition that requires an immediate evaluation and treatment.

2. Why Does Biliary Atresia Occur in Babies?

The exact reason for biliary atresia is still unknown. It is believed that abnormalities in the development of bile ducts, certain immune system activities, and even some infections can be contributing factors.

It is important to know that biliary atresia is not the result of something a parent did while pregnant. The diagnosis is often parents’ first experience with the medical field, and they usually feel a strong sense of guilt and self-blame. In the great majority of cases, there is no answer.

It is not a hereditary disease in the great majority of cases, and researchers are studying genetic and environmental factors that may be related to its onset.

Because the cause is unknown, doctors are primarily concerned with early detection in order to prevent further liver damage.

3. Early Symptoms of Biliary Atresia

These symptoms must be recognized as quickly as possible. Many of these symptoms can resemble common problems with newborns, so both the parents and the medical personnel taking care of the newborns must be diligent.

Persistent Yellow Skin or Eyes

Jaundice is common in the first few days of a baby’s life, but if jaundice does not go away or gets worse, then it requires further evaluation.

Babies with biliary atresia have persistent yellow skin and eyes because bilirubin builds up in the blood. Bilirubin is a substance that is normally filtered and excreted by the bile.

Pale, Grey, or Clay-Colored Stools

This is one of the important warning signs.

Bile is normally secreted in the intestine and helps to give stool its brown or yellow color. When bile is not secreted into the intestine, then stools can be very pale, gray, white, or clay-colored.

Parents should not take pale stools in a young baby as normal.

Dark Urine

Babies with biliary atresia have dark urine because certain forms of bilirubin are filtered in the kidneys and end up in the urine.

Poor Weight Gain

When the liver is affected, some babies have poor weight gain because they also have poor feeding. When there are multiple symptoms of prolonged jaundice and pale stools, then poor weight gain warrants further evaluation.

Enlarged Liver or Abdomen

When bile builds up, then the liver becomes enlarged and inflamed. Parents may notice an enlarged abdomen, but usually a doctor will notice it during an examination.

Simple advice: any persistent jaundice plus pale stools equals an urgent need for medical help.

4. The Importance of Early Diagnosis

There is a big emphasis on early diagnosis for biliary atresia.

As bile continues to build up in the liver, it can cause more damage and irreversible scarring. It is possible that if treatment is started early enough, the liver function can be preserved and a transplant can be avoided.

Parents should not think that their child’s jaundice is just “normal newborn jaundice” that will go away on its own.

There are many potential causes of jaundice, and a pediatrician will evaluate the child for those causes. If the child’s case is not improving and it is suspected that the issue may be with the flow of bile, the child will then be referred to a pediatric gastroenterologist, hepatologist, or a liver specialist.

The medical team can implement a wider variety of treatment options if the diagnosis is made earlier. This is especially true if there is not significant irreversible damage to the liver.

5. How Is It Diagnosed?

There is no test that will definitely diagnose biliary atresia. Doctors will look at the child’s symptoms and examine the child, then order blood work and possibly imaging. Some may even use a surgical method to evaluate the child.

Other Imaging Tests

In some cases, doctors order specific imaging tests to evaluate the flow of bile and the anatomy of the liver and bile ducts.

Liver Biopsy

In some cases, a small tissue sample from the liver is removed and viewed under a microscope to help assess the degree and type of injury to the liver and help with the diagnosis.

Cholangiography

This test helps evaluate the bile ducts and is often performed during surgery when biliary atresia is suspected. If the test confirms the diagnosis of biliary atresia, then the surgical team will perform the necessary treatment during the same surgery.

6. Kasai Procedure for Biliary Atresia

The Kasai portoenterostomy is the first line of surgical treatment for biliary atresia.

During this procedure, the bile duct structures are removed or resected and a direct pathway is created between the liver and the intestine to allow for the drainage of bile from the liver.

The goal is to allow bile to flow from the liver to the intestine and to decrease the amount of bile that is trapped in the liver.

The success of the Kasai procedure can be impacted by how old the child is when the procedure is performed and the level of injury and scarring of the liver.

Parents need to understand that the Kasai procedure is not a permanent cure. Some children can develop progressive liver disease despite a successful Kasai procedure and bile drainage.

A child can require long-term monitoring even if the first procedure improves the condition.

7. When Is Liver Transplant Needed?

Liver transplantation may be necessary when biliary atresia causes more advanced or irreversible liver disease.

Some children may develop extensive scarring of the liver, known as cirrhosis. Others may develop complications despite treatment.

A transplant may be considered when the liver becomes enlarged and function is impaired to the extent that it cannot perform its basic functions, or when complications become life-threatening.

Reasons for transplantation may include:

• Progressive liver failure
• Advanced cirrhosis
• Severe portal hypertension
• Repeat complications of liver disease
• Poor growth and nutrition
• Fluid retention
• Bleeding due to portal hypertension
• Other signs of deterioration of liver function

The decision is individualized. The child’s overall health, liver function, complications, growth, and nutrition must be taken into consideration along with other medical issues.

8. Living Donor Liver Transplant in Children

Living donor liver transplantation is an important option for children with advanced liver disease.

In a living donor transplant, a portion of the healthy adult donor’s liver is transplanted into the child. The adult donor’s liver and the child’s liver both grow back to full size.

For a child, a living donor may be advantageous because transplantation can be timed based on the child’s medical needs rather than waiting for an appropriate organ from a deceased donor.

However, a potential donor must go through a thorough evaluation which includes a number of medical and psychological tests to ensure that donation is safe and appropriate.

Both the donor and the child need specialized care before, during, and after the transplant process.

9. What Happens Before a Liver Transplant?

A pediatric liver transplant is a lengthy and complicated procedure, so the preparation is understandably thorough.

The child undergoes a series of tests that may include:

• Blood tests
• Imaging studies
• Assessment of liver function
• Nutritional evaluation
• Heart and lung assessment, if necessary
• Infection screening
• Assessment of kidney function
• Evaluation for transplant-related complications

The transplant team also determines if the child is fit to undergo the surgical procedure.

For a living donor transplant, the potential donor undergoes a similar assessment to determine the anatomy and health of the liver, and the donor’s overall health and suitability for the procedure.

At this stage, many parents have questions. How risky is the surgery? How long will the recovery be? What medications will the child need to take after the surgery?

A good transplant center will take the time to explain each step in detail so that parents can make informed decisions.

10. Recovery After Pediatric Liver Transplant

Recovery after a liver transplant is a long and drawn-out process that begins immediately after surgery. The child is closely monitored in a specialized intensive care unit, and the transplant team assesses liver function, checks blood flow and vital signs, and looks for signs of complications.

Once the child is stable, the team slowly reintroduces normal activities, starting with regular meals and gradually increasing mobility.

Of all the activities and procedures that will be a part of your child’s new normal, taking immunosuppressant medications will probably be the most difficult to understand and accept. These medications will help prevent the child’s liver from being attacked and rejected by the body.

Parents must closely follow the prescribed medication schedule. Failure to do so can potentially cause the liver transplant to be rejected.

Blood tests and regular appointments are equally important. Doctors use the blood tests to assess the new liver and adjust the medications accordingly.

11. Long-Term Care After Transplant

A liver transplant saves a patient’s life, but it is only the first step in a lifetime of managing liver health.

Children will need to be closely monitored for the rest of their life. The transplant team will assess:

• Liver function
• Medication levels
• Growth and development
• Kidney function
• Nutrition
• Blood pressure
• Infections
• Rejection
• Other side effects of the medication

The healthcare team will also manage the child’s liver health for as long as they live and grow, and will offer guidance on things such as school, physical activity, nutrition, vaccinations, and other aspects of daily life.

With good follow-up care and adherence to the medications, children can go back to their normal, active lifestyle after the transplant.

12. Choosing the Right Liver Transplant Team

Families must make many important decisions for their child, and choosing a pediatric liver transplant center is one of the most difficult.

While choosing the best liver transplant surgeon in India, parents must look beyond advertisements and titles. Work experience in pediatric liver disease and transplantation is more valuable than experience in adult liver transplants because of the large anatomical, nutritional, and medical differences between children and adults.

When speaking with transplant centers, you might ask:

• Are there members of your team with pediatric liver transplantation experience?
• How many pediatric liver transplants do you perform on average?
• Do you perform living donor transplants?
• Do you have a dedicated pediatric intensive care unit?
• Do you have pediatric transplant specialists and hepatologists?
• What kind of support does the team provide pre and post-transplant?
• How do you manage potential complications?
• What kind of care do you provide to help manage potential complications once the child is discharged?
• What kind of support does the team provide once the child is discharged?

A team that is able to provide all of these supports can make a significant difference.

When looking for a transplant team, the focus should be on a team that is experienced in pediatric liver transplantation and has the necessary supports, team members that provide transparent communication and comprehensive care once the child is discharged.

Early diagnosis of biliary atresia does not mean your baby has biliary atresia. It means that we are considering biliary atresia as one of the possibilities and ruling it out.

13. When to Seek Medical Help?

Biliary atresia is a serious condition that requires early recognition and diagnosis to help alleviate the condition. A child can benefit from early surgical intervention and specialized care. The Kasai procedure is used to restore bile flow in children, and a liver transplant is used if a child requires it to save their life if they develop terminal liver disease.

The best thing a parent can do is act quickly and not panic. If your child has any of the following: persistent jaundice, pale or grey/clay-colored stools, and/or dark urine, then you should have your child immediately evaluated by a pediatric healthcare practitioner. A pediatric liver transplant team that has a lot of experience is best if your child requires a liver transplant. They will be able to provide the most comprehensive care throughout the transplant process.

14. Summary

Biliary atresia is a serious condition that requires early recognition, diagnosis, and treatment. Understanding the warning signs, including persistent jaundice, pale or clay-colored stools, and dark urine, can help parents seek medical attention promptly.

Early treatment may improve outcomes and, in some children, help delay or avoid liver transplantation. When advanced liver disease develops, liver transplantation can provide a lifesaving treatment option.

15. FAQs

1. What is the first warning sign of biliary atresia in babies?

Persistent jaundice is one of the main warning signs of biliary atresia. Pale or clay/gray-colored stools and dark urine are other symptoms that require an immediate need for medical evaluation.

2. Can biliary atresia be cured without a liver transplant?

The Kasai procedure can cure biliary atresia in some children and postpone or avoid a liver transplantation. Some children will still develop terminal liver disease and require a liver transplantation.

3. What age do medical professionals typically assign for a liver transplant for a child with biliary atresia?

It is difficult to assign a specific age for liver transplantation for biliary atresia. Many factors contribute to the decision, such as the severity of the child’s liver disease, the presence of complications, the child’s growth and nutrition, and the child’s response to treatment.

4. Can a parent donate a portion of their liver to a child with biliary atresia?

Yes, in appropriate cases, other adults, including parents, can be considered living liver donors. Prior to donating, the potential donor undergoes a thorough medical evaluation to ensure donation poses no risk to the donor.

5. What criteria should I use to identify the best liver transplant surgeon in India for my child?

The best liver transplant surgeons in India for children have performed many transplant surgeries, work in a transplant team with a wide range of specialties, have a pediatric intensive care unit, have the ability to perform a living donor transplant when necessary, and provide long-term care and follow-up services for the children they treat. It is important that you speak with the transplant team about your child’s case directly in order to make an informed decision.
