A Congenital Defect in Infants (Biliary Atresia)

Biliary atresia is a congenital or acquired defect in the biliary transport system that occurs at birth or in a few weeks after birth. Bile produced by the liver is carried via ducts to the intestine to help in the digestion of fats. The ducts present in the liver are called intra-hepatic ducts and the ones present outside the liver are called extra-hepatic ducts.
