description | Gastrointestinal (GI) bleeding is not a single disease but a symptom and clinical manifestation of a
broad spectrum of conditions in the GI tract. According to its clinical presentation, GI bleeding can be
classified into overt, occult, and obscure types. Additionally, it can be divided into upper and lower GI
bleeding based on the Treitz ligament. Variable disease entities, including vascular lesions, polyps,
neoplasms, inflammation such as Crohn’s disease, and heterotopic pancreatic or gastric tissue, can
cause GI bleeding. CT and conventional angiographies and nuclear scintigraphy are all radiologic imaging
modalities that can be used to evaluate overt bleeding. For the work-up of occult GI bleeding, CT
enterography (CTE) can be the first imaging modality. For CTE, an adequate bowel distention is critical
for obtaining acceptable diagnostic performance as well as minimizing false positives and negatives.
Meckel’s scintigraphy can be complementarily useful in cases where the diagnosis of CTE is suboptimal.
For the evaluation of obscured GI bleeding, various imaging modalities can be used based on
clinical status and providers’ preferences. |
