Study Notes
Ischemic Colitis Overview
- Caused by reduced blood supply to the colon.
- Blood supply comes from superior and inferior mesenteric arteries.
- Splenic flexure and cecum are most at risk.
Epidemiology
- Most common in older adults.
- Linked to atherosclerosis and blood vessel blockage.
- Younger patients may have it related to oral contraceptives, blood clotting disorders, and blood vessel inflammation.
Clinical Features
- Symptoms include abdominal pain, rectal bleeding, and sometimes shock.
- Sigmoidoscopy often shows normal tissue, but with blood present.
Management
- Treatment is usually supportive.
- Surgery may be needed for potential complications such as gangrene, perforation, and stricture formation.
