Abstract: | Preoperative upper abdominal ultrasonograms of babies with biliary atresia were reviewed in order to determine the efficacy of this technique in the differential diagnosis of biliary atresia and neonatal hepatitis. In 4 patients with neonatal hepatitis and 8 normal controls, ultrasonograms showed echoes of the gallbladder. In 14 patients with biliary atresia, echoes of the gallbladder were not apparent. It is concluded that preoperative ultrasonograms provide an efficient diagnostic method for differentiating biliary atresia from neonatal hepatitis.Offprint requests to: T. Okasora |
