    Insights

    Computed tomography (CT) can identify excluded stomach dilation after gastric bypass surgery, which causes patient symptoms. CT is superior to upper gastrointestinal series for evaluating the excluded stomach in these patients.

    Area of Science:

    • Medical Imaging
    • Gastroenterology
    • Surgical Outcomes

    Background:

    • Gastric bypass surgery is a common bariatric procedure.
    • Post-surgical complications can arise from the excluded stomach.
    • Standard imaging may not adequately visualize the excluded stomach.

    Purpose of the Study:

    • To evaluate the utility of computed tomography (CT) in assessing the excluded stomach after gastric bypass.
    • To determine if CT can identify abnormalities in the excluded stomach contributing to patient symptoms.

    Main Methods:

    • Retrospective review of eleven patients who underwent gastric bypass.
    • Computed tomography (CT) scans were used to examine the excluded stomach.
    • Clinical correlation of imaging findings with patient symptomatology.

    Main Results:

    • Three out of eleven patients presented with dilated excluded stomachs.
    • This dilation was directly correlated with the patients' presenting symptoms.
    • Computed tomography (CT) successfully delineated the excluded stomach anatomy.

    Conclusions:

    • Computed tomography (CT) is an effective imaging modality for evaluating the excluded stomach post-gastric bypass.
    • CT can identify excluded stomach dilation as a cause of post-operative symptoms.
    • CT is recommended over upper gastrointestinal series for excluded stomach assessment.

    Computed Tomography

    Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
    The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

    Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

    This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
    Radionuclide Testing
    Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
    In gastric emptying studies, a meal's liquid and solid...
