目的 探讨缺血性结肠炎的临床特点、内镜特征及诊断和治疗方法.方法 对56例缺血性结肠炎患者的临床资料进行回顾性分析.结果 缺血性结肠炎多发生于老年患者,男女比例为1∶1.8.多伴有糖尿病（53.6％,30/56）、高血压（39.3％,22/56）、冠心病（32.1％,18/56）等基础疾病.腹痛（100.0％,56/56）及便血（89.3％,50/56）为主要临床表现.结肠镜检查以黏膜充血、水肿、糜烂、溃疡等非特异性表现为主,病变主要见于左半结肠,呈节段性分布.多数患者预后良好.结论 老年患者出现急性腹痛和便血时应警惕缺血性结肠炎可能,早期结肠镜检查可及时明确诊断和指导治疗.

Retrospective analysis on 56 ischemic colitis

Objective To analyze the clinical features,endoscopic characteristics and methods for diagnosis and treatment of isehemic colitis. Methods The clinical data of 56 patients with ischemic colitis were retrospectively analyzed. Results Ischemie colitis occurred more often in elderly patients. Male and female ratio was 1 ：1.8. The patients often had concomitant basic diseases,such as diabetes mellitus （53.6%, 30/56 ）, hypertension （ 39.3%, 22/56）, coronary heart disease （32.1%, 18/56 ）. The main manifestations of ischemic colitis were abdominal pain （ 100.0%, 56/56） and bloody stools （89.3%, 50/56）. The lesions revealed by colonoscopy were mainly located in the left colon and distributed in a segmental pattern,and the pathological changes included mucosal edema,congestion,erosion and ulceration. The prognosis was good in most cases. Conclusions Ischemic colitis should be suspected in elderly patients with acute abdominal pain and bloody stools. Early eolonoscopy is helpful for accurate diagnosis and appropriate treatment of ischemic colitis.
