Principles of treatment for ischemic colitis: First, fasting and giving medium to high flow feedings. Second, active elimination of causative factors and treatment of concomitant morbidity. The development of the majority of non-gangrenous lesions confined to the intestinal wall is self-limiting and can be gradually absorbed, and even if colonic stenosis occurs in some patients, it is mostly incomplete and can be relieved by conservative treatment. 2. The mortality rate of gangrenous ischemic colitis depends largely on the promptness of diagnosis and surgical treatment, the patient’s general condition and the occurrence of complications. In case of respiratory distress syndrome, renal failure and persistent severe infectious complications, the mortality rate is high. Therefore, surgical treatment is mostly limited to gangrenous patients with ischemic colitis and should be performed as soon as the diagnosis is confirmed.
