Abstract Objective: To summarize and analyse the ultrasonographic findings of 20 infants with biliary atresia(BA), and to evaluate its diagnostic value. Methods: The color Doppler ultrasonography(US) was performed in 20 infants with BA. The size and echo of liver and spleen, fasting gallbladder and its dynamic change after meal, fibrotic mass in hepatic hilum were observed. Results: The fibrotic mass in hepatic hilum was significantly present in 10 of the 20 infants with BA. Three had small fibrotic mass, 2 had no gallbladder, 1 infant’s gallbladder had no lumen, 15 had small gallbladder without dynamic change after meal, 2 had the normal size and shape of gallbladder but no contraction after meal. All infants had different degree of hepatomegaly, 9 had small amount of fluid in abdominal cavity, 14 had splenomegaly. Conclusions: The fibrotic mass in hepatic hilum is an objective and specific criterion for diagnosing BA with US. The little gallbladder, especially no contraction function of gallbladder was valuable for diagnosis and differential diagnosis of BA. Hepatomegaly and coarsening of liver parenchyma echogenicity was positively relative with hepatic fibrosis, which may suggest the course and prognosis of BA.
