Overview
Fluoroscopy barium studies are rarely used in diagnosis of ischemic colitis. Contrast enema is abnormal in 90% of patients but is rarely used for diagnostic purposes. Barium enema should be avoided in cases where there is a suspicion of gangrene or perforation. Also, barium enema makes the later use of angiography or endoscopy more difficult because of residual contrast agent.
Other imaging findings
Barium findings in ischemic colitis are as follows:[1][2]
- Fluoroscopy barium studies may be used in diagnosis of ischemic colitis.
- Contrast enema is abnormal in 90% of patients but is rarely used for diagnostic purposes.
- The findings are:
- Segmental region of abnormality
- Thumbprinting which is classically obliterated by air insufflation
- Spasm
- Ulcerations serrated mucosa
- Stricture from fibrosis
- Barium enema should be avoided in cases where there is a suspicion of gangrene or perforation.
- Barium enema makes the later use of angiography or endoscopy more difficult because of residual contrast agent.
