소장 폐쇄증과 동반된 담도 폐쇄증

Abstract

Biliary atresia is a progressive obliterative cholangiopathy, but its actual causes are still unknown. However, a number of factors, such as developmental malformation, viral infection, toxicity of bile constituents and an anatomical abnormality in the hepatobiliary system, have been considered. Herein, two very unusual cases of biliary atresia, associated with ileal atresia, are reported. The pathogenesis of this particular type of biliary atresia is still a matter for debate.
