Overview
Biliary atresia is a blockage in the tubes (ducts) that carry a liquid called bile from the liver to the gallbladder. The condition is congenital, which means it is present from birth.
What are the symptoms of biliary atresia?
- Newborns with this condition may appear normal at birth. However, jaundice (a yellow color to the skin and mucous membranes) develops by the second or third week of life.
- The infant may gain weight normally for the first month, but then will lose weight and become irritable, and have worsening jaundice.
- Other symptoms may include:
- Dark urine
- Enlarged spleen
- Floating stools
- Foul-smelling stools
- Pale or clay-colored stools
- Slow growth
- Slow or no weight gain
Who is at highest risk?
Biliary atresia is common form of chronic liver disease in newborns, affecting one in every 15,000 live births. As with many congenital conditions, a family history of biliary atresia increases the likelihood of potential for having the condition. Genetically, biliary atresia is linked most frequently to Asian and African American populations. Comparative, as many as two times the number of African Americans are affected with biliary atresia as compared to their Caucasian counterparts.
What causes Biliary atresia?
- Biliary atresia occurs when the bile ducts inside or outside the liver do not develop normally. It is not known why the biliary system fails to develop normally.
- The bile ducts help remove waste from the liver and carry salts that help the small intestine break down (digest) fat.
- In babies with biliary atresia, bile flow from the liver to the gallbladder is blocked. This can lead to liver damage and cirrhosis of the liver, which is deadly if not treated.
When to seek urgent medical care?
Call your health care provider if your child appears jaundiced, or if other symptoms of biliary atresia develop.
Diagnosis
- The health care provider will perform a physical exam, which includes feeling the patient's belly area. The doctor may feel an enlarged liver.
- Tests to diagnose biliary atresia include:
- Abdominal x-ray
- Abdominal ultrasound
- Blood tests to check total and direct bilirubin levels
- Hepatobiliary iminodiacetic acid (HIDA) scan, also called cholescintigraphy, to help determine whether the bile ducts and gallbladder are working properly
- Liver biopsy to determine the severity of cirrhosis or to rule out other causes of jaundice
- X-ray of the bile ducts (cholangiogram)
Treatment options
- An operation called the Kasai procedure is done to connect the liver to the small intestine, going around the abnormal ducts. It is most successful if done before the baby is 8 weeks old. However, a liver transplant may still be needed.
Where to find medical care for Biliary atresia?
Directions to Hospitals Treating Biliary atresia
What to expect (Outlook/Prognosis)?
- Early surgery will improve the survival of more than a third of babies with this condition.
- The long-term benefit of liver transplant is not yet known, but is expected to improve survival.
Possible complications
- Infection
- Irreversible cirrhosis
- Liver failure
- Surgical complications, including failure of the Kasai procedure
