Biliary Atresia, Extrahepatic; Ehba
Biliary atresia is a disorder of infants in which there is progressive obliteration or discontinuity of the extrahepatic biliary system, resulting in obstruction of bile flow.

Most patients require liver transplantation within the first year of life (Leyva-Vega et al., 2010).See also Alagille syndrome (OMIM ), which includes biliary atresia as a feature.
