Biliary atresia (BA) is a progressive, idiopathic, fibro-obliterative disease of the extrahepatic biliary tree that presents with biliary obstruction exclusively in the neonatal period. Blah, blah, blah. What that means in everyday terms is that the system of tubes that drains bile from the liver to the small intestine (which the gallbladder is part of) become narrow and often close off. This results in a blockage causing a build up and back flow of bile in the liver and eventually the blood stream.
