Diagnostic Problems in Infantile Cholestatic Jaundice
Abstract
A diagnostic laparotomy was retrospectively assessed for reliability in 173 infants, between 1-4 months of age, who were treated at the Children's Hospital during 1990-1995. Cases of cholestatic jaundice associated with sepsis or concomitant administration of parenteral nutrition were not included in the study. Data from this study supported the reliability of the criteria. If these criteria were strictly followed, none of the inf ants with biliary atresia (BA) in this study would be missed. However, about 25 per cent of infants with neonatal hepatitis (NH) would have to be subject to a diagnostic laparotomy.
It is concluded that any infant with cholestatic jaundice and acholic stool should undergo a diagnostic laparotomy at the age of 2 months if total serum bilirubin is 6-25 mg/dl, unless there is a steady decrease of serum bilirubin and the cause of jaundice is documented by other laboratory investigations and clinical evidences. Those who have a positive serology test for syphilis should be treated accordingly and closely ed. If the infants' jaundice and stool colour are not improved in an expected timing and should also undergo a diagnostic laparotomy. Radionuclide hepatobiliary scan needs further assessment for its sensitivity. If this test can be proved to have a 100 per cent sensitivity, it could be included in the screening criteria. UItrasonographic study should be done in every case in order to detect choledochal cyst, but not to differentiate NH from BA.
