    Summary

    Persistent neonatal jaundice can be diagnosed using imaging. Sonography and hepatobiliary scintigraphy effectively differentiate conditions like neonatal hepatitis and biliary atresia, guiding prompt treatment.

    Area of Science:

    • Pediatric Gastroenterology
    • Diagnostic Imaging
    • Hepatology

    Background:

    • Persistent neonatal jaundice requires accurate diagnosis to differentiate between medical and surgical conditions.
    • Neonatal hepatitis and biliary atresia are common causes of prolonged jaundice in infants.
    • Sonographic findings for these conditions can be nonspecific, necessitating functional assessment.

    Purpose of the Study:

    • To evaluate the utility of sonography and radionuclide scintigraphy in diagnosing persistent neonatal jaundice.
    • To differentiate between neonatal hepatitis, biliary atresia, and choledochal cysts.
    • To establish an expedient diagnostic approach for persistent neonatal jaundice.

    Main Methods:

    • Fifteen patients with persistent neonatal jaundice underwent sonography and hepatobiliary scintigraphy.
    • Phenobarbital pretreatment was used to enhance scintigraphic evaluation of hepatobiliary function.
    • Sonography assessed anatomical structures, while scintigraphy evaluated tracer uptake and excretion.

    Main Results:

    • Sonography showed nonspecific features for neonatal hepatitis and biliary atresia.
    • Hepatobiliary scintigraphy revealed distinct patterns: normal hepatic extraction with delayed excretion in neonatal hepatitis, absent excretion in biliary atresia, and communication with the biliary system in choledochal cysts.
    • Phenobarbital-enhanced scintigraphy proved crucial for functional assessment.

    Conclusions:

    • Sonography provides initial anatomical information for neonatal jaundice evaluation.
    • Phenobarbital-enhanced hepatobiliary scintigraphy is essential for determining hepatobiliary function and differentiating causes of jaundice.
    • An integrated diagnostic approach combining sonography and scintigraphy is recommended for efficient evaluation of persistent neonatal jaundice.
