    Summary
    This summary is machine-generated.

    Diagnosing sphincter of Oddi dysfunction in post-cholecystectomy patients can be challenging. This study confirms its functional nature using specific diagnostic tests when organic blockages are excluded.

    Area of Science:

    • Gastroenterology
    • Hepatobiliary Medicine

    Background:

    • Sphincter of Oddi dysfunction (SOD) poses diagnostic challenges, particularly in patients who have undergone cholecystectomy.
    • Differentiating functional SOD from organic biliary obstruction is crucial for appropriate management.

    Purpose of the Study:

    • To discuss the diagnostic difficulties of sphincter of Oddi dysfunction in post-cholecystectomy patients.
    • To verify the functional nature of biliary flow issues when organic lesions are absent.

    Main Methods:

    • Utilized the morphine-choleretic test to assess biliary dynamics.
    • Combined the morphine-choleretic test with dynamic hepatobiliary scintigraphy.
    • Employed percutaneous transhepatic cholangiography for further diagnostic clarification.

    Main Results:

    • Successfully ruled out organic lesions obstructing bile flow in all evaluated cases.
    • Confirmed the functional nature of the observed biliary issues.
    • Demonstrated the utility of the combined diagnostic approach.

    Conclusions:

    • The morphine-choleretic test, alongside imaging modalities like hepatobiliary scintigraphy or cholangiography, is effective in diagnosing functional sphincter of Oddi dysfunction.
    • Accurate diagnosis is achievable even in the absence of organic biliary obstruction in post-cholecystectomy patients.
