About This Condition

Congenital Liver Defects

What are congenital liver defects?

Congenital liver defects are liver disorders that are present at birth. They are rare. These liver disorders usually block the bile ducts. This affects the flow of bile. Bile is a fluid made in the liver. It helps with digestion. The bile ducts take bile from the liver and bring it to the gallbladder to be stored. Then they carry bile to the small intestine for digestion.

When the bile ducts are blocked, bile builds up in the liver. This damages the liver.

Some congenital liver defects include:

  • Biliary atresia. A life-threatening condition in infants where the bile ducts are blocked or have developed abnormally. This blocks the flow of bile from the liver.
  • Biliary (choledochal) cyst. A condition where the hepatic duct forms abnormally. This can also block the flow of bile.
  • Alagille syndrome. Too few bile ducts associated with other abnormalities including heart, bone, facial features, eye, and others.

What causes congenital liver defects?

Healthcare providers don't know the exact cause of congenital liver defects. Most likely they are caused by something that happened as the fetus was developing or around the time of birth. This might happen because of one or more of the following:

  • A viral or bacterial infection after birth
  • An immune system problem, such as when the immune system attacks the liver or bile ducts for unknown reasons
  • A genetic mutation. This is a long-lasting change in a gene’s structure.
  • A problem during liver and bile duct development in the fetus
  • Contact with toxic substances

What are the symptoms of congenital liver defects?

Congenital liver defects that affect the flow of bile share some common symptoms. Each child’s symptoms may vary, but may include:

  • Yellowing of the skin and eyes (jaundice)
  • Dark-colored urine
  • Pale, white, or gray-colored stools
  • Belly mass
  • Belly pain
  • Not gaining weight (failure to thrive)

The symptoms of congenital liver defects may look like other health problems. Always talk with your child's healthcare provider for a diagnosis.

How are congenital liver defects diagnosed?

In most cases, congenital liver defects that affect the flow of bile are diagnosed at birth or soon after. Your child’s healthcare provider will take a full health history and do a physical exam. Your child may also have tests. These include:

  • Lab tests (blood, urine, and stool).
  • Liver enzyme tests. Special blood tests to check if the liver is red or swollen (inflamed).
  • Liver function tests. Special blood tests to see if the liver is working the way it should.
  • Genetic tests. Tests that look for certain traits, diseases, or being susceptible to a disease that may result in descendants having the disease or condition. Genetic tests include prenatal genetic testing.
  • Liver biopsy. Tissue samples from the liver are removed (with a needle or during surgery) and checked under a microscope.
  • CT scan. This is an imaging test that uses X-rays and a computer to make detailed images of the body. A CT scan shows details of the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
  • Ultrasound. This imaging test uses high-frequency sound waves and a computer. It creates images of blood vessels, tissues, and organs. It is used to see internal abdominal organs such as the liver, spleen, and kidneys. An ultrasound can check blood flow through different vessels.
  • MRI. This imaging test uses a combination of large magnets, radio frequencies, and a computer. It makes detailed images of organs and structures in the body. MRCP (magnetic resonance cholangiopancreatography) is a special type of MRI that takes pictures of the bile duct and internal organs.

How are congenital liver defects treated?

Treatment will depend on the type of congenital liver defect your child has. Surgery may be needed.

If your child has a choledochal cyst, he or she must have surgery to remove the cyst and allow normal bile flow. The type of surgery will depend on where the cyst is located, as well as other factors.

Infants with biliary atresia are treated with a type of surgery called the Kasai procedure. This removes the damaged bile ducts and replaces them with a section of small intestine. Bile then flows right to the small intestine. A liver transplant may be needed.

What are the complications of congenital liver defects?

If untreated, congenital liver defects can lead to liver damage and death.

Living with congenital liver defects

Once surgery is done and the defect is repaired, children can often lead healthy lives. This will also depend on how much liver damage occurred before the surgery.

If your child had a liver transplant:

  • He or she must take anti-rejection medicines (immunosuppressants). These medicines help stop the immune system from attacking the new liver. Your child will have to take these medicines for as long as he or she has the new liver.
  • Your child will likely need to take vitamin supplements.

After treatment, your child should be checked regularly by his or her healthcare team.

Your child's provider may suggest support groups. This can help you and your child adjust to his or her condition.

When should I call my child's healthcare provider?

If your child has any symptoms of a congenital liver defect, call your child's provider right away. Also call the provider if your child develops symptoms after treatment.

If your child had a liver transplant, ask your child's healthcare team what rejection symptoms you should look for. Also ask them when to call your child's healthcare provider.

Tips to help you get the most from a visit to your child’s healthcare provider:

  • Know the reason for the visit and what you want to happen.
  • Before your visit, write down questions you want answered.
  • At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you for your child.
  • Know why a new medicine or treatment is prescribed and how it will help your child. Also know what the side effects are.
  • Ask if your child’s condition can be treated in other ways.
  • Know why a test or procedure is recommended and what the results could mean.
