    Summary

    Cholescintigraphy using 99Tcm-HIDA is crucial for diagnosing congenital biliary atresia in infants. This imaging technique aids in confirming the diagnosis before surgery and evaluating liver function post-operation.

    Area of Science:

    • Pediatric Surgery
    • Diagnostic Imaging
    • Hepatology

    Background:

    • Congenital biliary atresia presents a diagnostic challenge in neonates.
    • Early diagnosis is critical for effective surgical intervention and improved outcomes.
    • Distinguishing biliary atresia from other causes of neonatal jaundice requires reliable imaging modalities.

    Observation:

    • The study reviewed five cases of suspected congenital biliary atresia.
    • Cholescintigraphy utilizing technetium-99m-labeled iminodiacetic acid (99Tcm-HIDA) was performed in four cases.
    • The imaging findings were correlated with surgical confirmations.

    Findings:

    • 99Tcm-HIDA scintigraphy provided accurate preoperative diagnosis in four out of five suspected congenital biliary atresia cases.
    • The diagnostic accuracy of cholescintigraphy facilitated safe surgical planning.
    • The procedure proved effective in confirming the presence or absence of biliary atresia.

    Implications:

    • Cholescintigraphy with 99Tcm-HIDA should be considered an essential tool in the diagnostic workup of congenital biliary atresia.
    • This imaging modality is vital for preoperative assessment and postoperative evaluation of hepatic-porto-enterostomy function.
    • Implementing 99Tcm-HIDA scintigraphy can improve the management of neonatal cholestasis and biliary disorders.
