    The echographic method effectively evaluates gallbladder function after cholecystokinin (CCK) stimulation, offering a cost-effective and comfortable alternative to the HIDA-CCK test for assessing gallbladder contraction and emptying.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Hepatobiliary System

    Background:

    • Gallbladder function assessment is crucial for diagnosing biliary disorders.
    • Cholecystokinin (CCK) stimulation is a standard method to evaluate gallbladder response.
    • Comparing diagnostic modalities for gallbladder function is essential for clinical practice.

    Purpose of the Study:

    • To compare the efficacy of echography versus scintigraphy (HIDA-CCK test) in evaluating gallbladder function post-CCK stimulation.
    • To determine if echography can serve as a viable alternative to the HIDA-CCK test.

    Main Methods:

    • Echography: Measured changes in gallbladder face area after CCK injection.
    • Scintigraphy (HIDA-CCK test): Assessed gallbladder emptying by external counts.

  • Performed 20 studies, analyzing contractile response, emptying time (T1/2), and initial response time (Ti).

    • Main Results:

    • 8 studies showed normal contraction and emptying.
    • 7 studies exhibited delayed response (Ti) and slower emptying (T1/2).
    • 5 studies showed no gallbladder response to CCK via HIDA; one had incomplete contraction on echography.
    • High linear correlation (0.8255) between methods in normal and delayed response groups.

    Conclusions:

    • Echography provides a reliable assessment of gallbladder contraction following CCK administration.
    • Echography is a cost-effective, comfortable, and readily available alternative to the HIDA-CCK test.
    • Echographic evaluation of gallbladder function is recommended for clinical use.
