Methods 101 cases with ischemic colitis underwent endosopy within 14 days of onset of symptom in center of our hospital were retrospectively reviewed for their endosopic findings , clinicopathologic characteristics and risk factors. Results The common features of 101 cases included abdominal pain,diarrhea,or bloody diarrhea and hematochezia. Endoscopic visualization of mild ischemic colitis included pete-chial hemorrhages,edematous and fragile mucosa,segmental erythema,scattered erosion,longitudinal ulcerations,and sharply defined segment of involvement. Stricture ischemic colitis was characterised by full-thickness mucosa, lumens stricture and haustrations disappeared. Clinicpathological examination revealed mucosal inflammation accompanied by erosion,granulation tissue hyperplasis and gland atrophy,lamina propria hemorrhage,especially macrophages with he-mosiderin pigmentation in submucosa. Hypertension pressure, diabetes, atrial fibrilation were risk factors for ischemic colitis ( P < 0.05 ). Conclusion Although there was on specific changes on endoscopic findings and pathologic characteristics , but combined with history, was helpfu in diagnosis of ischemic colitis and reducing the misdiagnosis.
