    Technetium-99m labeled hepatobiliary iminodiacetic acid (99mTc HIDA) scans accurately visualize hepaticojejunal bypass anastomoses. This cholescintigraphy method offers physiologic, anterograde imaging compared to other diagnostic techniques.

    Area of Science:

    • Nuclear Medicine
    • Gastroenterology
    • Surgical Imaging

    Background:

    • Hepaticojejunal bypass is a surgical procedure for various hepatobiliary indications.
    • Accurate follow-up imaging is crucial for assessing the patency and function of the anastomosis.
    • Conventional imaging modalities like echography and cholangiography have limitations.

    Purpose of the Study:

    • To evaluate the efficacy of 99mTc HIDA cholescintigraphy in the follow-up of patients with hepaticojejunal bypass.
    • To compare the diagnostic accuracy of 99mTc HIDA scans with other imaging techniques.

    Main Methods:

    • Retrospective analysis of 17 patients who underwent hepaticojejunal bypass.
    • Utilized 99mTc HIDA scintigraphy for imaging.
    • Compared results with echography and intravenous (IV) or percutaneous transhepatic cholangiography (PTC).

    Main Results:

    • 99mTc HIDA scintigraphy demonstrated accurate visualization of the hepaticojejunal anastomosis.
    • The procedure allowed for anterograde and physiologic imaging of the bypass.
    • Preliminary findings suggest high accuracy compared to conventional methods.

    Conclusions:

    • 99mTc HIDA cholescintigraphy is a reliable and accurate method for evaluating hepaticojejunal bypass.
    • It provides a physiologic assessment of anastomosis function.
    • This nuclear medicine technique complements or potentially surpasses other diagnostic tools in this context.
