Potential errors in the diagnosis and surgical management of neonatal jaundice.

Despite advances and refinements in diagnostic techniques, distinguishing between cholestatic syndromes and extrahepatic biliary atresia is not always possible. Because there are inherent errors in all diagnostic studies including nuclear scanning, ultrasonography, and liver biopsy some infants presumed to have biliary atresia will come to surgery when, in fact, the bile ducts are partially or completely patent. The decision to proceed with a portoenterostomy or to terminate the procedure depends upon the appearance of the liver and histology of the biopsy.
