[Ischemic colitis].

Ischaemic colitis is the most frequent form of mesenteric ischaemia and is most frequently the result of a non-occlusive disease process. Elderly patients, especially those with underlying co-morbid conditions are at greatest risk. The symptoms are often non-specific and diagnosis is usually established upon the clinical setting and colonoscopy with biopsy. In the majority of cases, ischaemic colitis can be treated non-surgically with a successful outcome.
