Long-term Complications
About 20% of patients with acute ischemic colitis may develop a long-term complication known as chronic ischemic colitis. Symptoms can include recurrent infections, bloody diarrhea, weight loss, and chronic abdominal pain. Chronic ischemic colitis is often treated with surgical removal of the chronically diseased portion of the bowel.
A colonic stricture is a band of scar tissue which forms as a result of the ischemic injury and narrows the lumen of the colon. Strictures are often treated observantly; they may heal spontaneously over 12–24 months. If a bowel obstruction develops as a result of the stricture, surgical resection is the usual treatment, although endoscopic dilatation and stenting have also been employed.

Famous quotes containing the word long-term:
“The strongest and most effective [force] in guaranteeing the long-term maintenance of ... power is not violence in all the forms deployed by the dominant to control the dominated, but consent in all the forms in which the dominated acquiesce in their own domination.”
—Maurice Godelier (b. 1934)
