Abstract
We have recently experienced three cases of colonic cancer with ischemic colitis. In all cases,colonoscopy revealed erosive change, mucosal edema , and longitudinal ulcer in the colon. According to the endoscopic findings , a diagnosis of ischemic colitis was made. Additionary, colonoscopy revealed advanced colonic cancer in the distal colon. The colonic cancers of all cases were treated surgically.Ischemic colitis occurs acutely with abdominal pain, diarrhea, and, hematochezia. Although relatively uncommon, we can find case reports of colonic cancer with ischemic colitis. In the case of ischemic colitis, we need to determine whether a colonic cancer exists.
