Biliary tract anomalies: the utilization of modern techniques in differential diagnosis.

The diagnostic aids used in dealing with biliary disease in adults were applied to the study in infants of the principal congenital anomalies of the biliary tract such as choledochal cyst, biliary atresia and biliary stenosis. Choledochal cysts were distinguished from other upper abdominal masses occurring in childhood by the use of intravenous cholecystography. Since the clinical manifestations in infants with biliary atresia or stenosis are almost identical to those associated with the obstructive phase of neonatal hepatitis, the problem of differentiation is difficult. The serial total serum bilirubin curve, a careful analysis of the pigment content of feces and urine and duodenal intubation for bilirubin determinations were found to be useful in making the distinction. Operative cholangiograms were helpful in some cases. Frozen section examinations of liver tissue during operation were of little value except to demonstrate certain unusual cases of intrahepatic biliary atresia. Routine liver function studies, including serum transaminase determination in a limited number of cases, did not help in differentiation.
