Abnormal choledocho-pancreatico ductal junction related to the etiology of infantile obstructive jaundice diseases.

According to our current radiologic, histopathologic, and experimental studies, the congenital stenosis associated with anomalous choledocho-pancreatico ductal junction is considered to be the most important etiologic factor in congenital biliary dilatation. Furthermore, the possibility of pancreatic juice reflux into the biliary tract due to the abnormal choledocho-pancreatico ductal junction, which could lead to obstructive cholangiopathy, was suggested in relation to the pathogenesis of congenital biliary atresia.
