Overview

Fluoroscopy barium studies rarely used in diagnosis of ischemic colitis. Contrast enema is abnormal in 90% of patients but is rarely used for diagnostic purposes.

Other imaging findings

• 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 also makes the later use of angiography or endoscopy more difficult because of residual contrast agent.
