The liver makes a substance called bile. It helps with digestion of food and helps carry waste out of the liver. Bile drains out of the liver through tubes called bile ducts. It drains through these ducts into the duodenum (the first part of the small intestine). If a child has biliary atresia, it means that some or all bile ducts aren't formed correctly, are damaged, or are missing. As a result, bile can't drain from the liver as it should.

Your child has been diagnosed with a hepatitis infection. Hepatitis causes inflammation of the liver. Many things can cause it. One of the causes is infection with a virus called the hepatitis C virus (HCV). In some cases, hepatitis C goes away on its own. But for most people, hepatitis C is a chronic (lifelong) problem. Hepatitis C almost never causes symptoms until later in the disease. Even so, hepatitis C can cause severe liver damage over time. And a child who has it can pass the virus to others.

Your child has been diagnosed with a hepatitis infection. Hepatitis causes inflammation of the liver. Many things can cause it. One of the causes is infection with a virus called the hepatitis B virus (HBV). The illness caused by HBV infection can be acute (short-term) or chronic (long-term). Acute hepatitis B causes flulike symptoms. It's usually mild in children. In most cases, the virus dies off after this acute infection. But if HBV stays in the child's body after the acute illness, this means the child has chronic hepatitis.

A HIDA scan is also called a hepatobiliary scintigraphy. It's a test that checks the function of your child’s liver, gallbladder, and bile ducts (tubes inside and outside the liver). It can show where bile is blocked or leaking.

A liver biopsy is a quick test that helps see how healthy your child's liver is. During a percutaneous liver biopsy, a needle is inserted through the skin and into the liver. A small sample of liver tissue is then taken. The tissue is sent to the lab to be studied.

Hepatitis is an inflammation of the liver. Many things can cause it. One cause is infection with the hepatitis A virus (HAV). This virus can spread through food or water. It can also spread from person to person through infected stool. In most cases, the virus doesn’t make children very sick. It may cause symptoms like the flu. But it likely won’t cause long-term problems.
