Although several hundred cases of ischemic colitis have been reported from western countries, no case has been reported in our country. Ischemic colitis is a well established entity. Clinicopathological manifestations, diagnosis, treatment and prognosis of the disease are well known. A majority of reported cases were not particularly unusual. Two cases, of which one showed an unusually long lasting acute episode but good prognosis, and the other presented a diagnostic problem and was found to have a fibrous stricture due to ischemic colitis in the sigmoid colon at surgery, were described and discussed in relation to their symptoms, diagnosis and prognosis.
