[Spontaneous colonic ischemia].

Spontaneous ischemic colitis is a frequent disease, affecting mostly elderly people and predominantly localised on the left and sigmoid colon. It is due to alterations of small vessels of the colon and/or modifications of the splanchnic blood flow. Spontaneous evolution is generally favorable with restitution ad integrum of the disease colon. The diagnosis of ischemic colitis is established from the clinical picture, CT-scan and colonoscopy. Surgery, under the form of colonic resection, is required in 15% of cases approximately, in case of colonic necrosis.
