Biliary atresia is a blockage in the tubes (ducts) that carry bile (a digestive liquid that helps break down fats) from the liver to the gallbladder and small intestine. Babies with biliary atresia are born with underdeveloped or blocked bile ducts. This means that bile from the liver is unable to reach the intestine, where it normally works to help digest food. Without treatment, bile builds up, causing injury to the liver, and develops into liver failure within the first two years of life.
Biliary atresia is a congenital condition, which means it is present from birth.
Newborns with this condition may appear normal. Jaundice (yellowing of the skin and whites of the eyes) develops by the second or third week of life. The infant may gain weight normally for the first few weeks. Other symptoms include:
