[Liver and ductal remnants of porta hepatis in biliary atresia: histopathology and clinical significance].

We studied the relationship between the histopathology of biliary atresia and its clinical significance. Liver biopsies were made in 30 patients and ductal remnants of porta hepatis were studied in 20. The criteria for the pathological diagnosis of hepatic fibrosis were described. We think that judging the severity of hepatic fibrosis may be useful in selecting the mode of Kasai's operation and estimating the prognosis of patients with biliary atresia.
