    Abstract:
    The ultrastructure of the interlobular bile ducts were observed in hepatic specimens obtained at surgery in ten patients with biliary atresia, in order to investigate the progress of their degeneration over time after the onset of the disease. As an index for the passage of time, the degree of fibrosis in the portal tracts was investigated. Then the ultrastructural features in the interlobular bile ducts were contrasted with the grading of portal fibrosis Generally, the ultrastructural changes of the interlobular bile ducts were more marked in the cases with severe portal fibrosis than that observed in the cases with mild fibrosis. This correlation suggests that the degeneration of the interlobular bile ducts progressively worsens over time after the obliteration of the extrahepatic bile duct.
