摘要
缺血性结肠炎(IC)是最常见的胃肠道缺血性疾病。各种原因引起的结肠血流减少均可引发本病。由于其发病率低,临床和内镜表现与炎症性肠病相近,很易延误诊断。综合以下特点:高龄发病、症状与体征不一致、既往有血管疾病史、结肠镜所见病变与正常肠黏膜分界清楚且很少累及直肠等,有助于本病的诊断。经禁食、补液、扩容、停用可疑药物、应用抗生素和有效的扩张血管药物等内科治疗,半数以上患者可获痊愈。坏疽型病例应及时手术治疗。
Ischemic colitis （IC） is the most common form of gastrointestinal ischemia. The disease may be caused by reduction in colonic blood flow due to a variety of causes. It is often diagnosed inaccurately because of its low incidence, and its clinical symptoms and colonoscopic findings mimic those of inflammatory bowel disease. The following characteristics may contribute to the diagnosis： elderly patients; discrepancy between symptoms and objective findings; history of comorbid vascular disease; colonoscopy showing a clear demarcation between the lesions and normal mucosa, and the rare involvement of rectum. More than half of the patients could heal by conservative measures as bowel rest, discontinuation of the suspicious drugs; administration of intravenous fluids, vasodilator, and antibiotics. Severe gangrenous IC and cases that fail to respond to medical management require surgical intervention.
