Computed tomographic evaluation of the excluded stomach in gastric bypass
The Journal of Computed Tomography
|July 1, 1984
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.
Abstract:
Eleven patients who had gastric bypass operations were examined with computed tomography to evaluate the status of the excluded stomach. Three of the patients had dilated excluded stomachs that accounted for the patients' symptomatology. As an upper gastrointestinal series cannot delineate the excluded stomach, computed tomography is the examination of choice for such an evaluation.
