老年人缺血性结肠炎临床特点

Ischemic Colitis in the Elderly

目的 :探讨老年缺血性结肠炎临床特点和易患因素。方法 :2 9例患者根据年龄分为老年组 (≥ 6 0岁 )和成年组 (<5 9岁 )。回顾分析其临床资料 ,并进行组间比较。结果 :(1)多数患者表现为腹痛、便血二联征 ,老年组肠梗阻发生率和病死率均高于成年组 ,但无显著差异。 (2 )老年组房颤患者显著多于成年组 (P <0 .0 5 ) ,动脉粥样硬化相关性疾病患病率显著高于成年组 (P <0 .0 0 1) ,而吸烟、高血压、糖尿病和高脂血症在两组间无显著差异。结论 :老年缺血性结肠炎临床表现典型 ,病情危重 ,病死率高。

Objective: To investigate the clinical characteristics and risk factors of ischemic colitis of elderly patients. Methods: 29 patients were divided into two groups according to their age. Clinical data of 17 elderly ischemic patients were retrospectively analyzed and were compared with those of 12 adult patients. Results: 1. Most patients presented with abdominal pain and bloody stools. The incidence of ileus and the mortality rate were higher in the elderly group than those in the adult group, but the difference was not significant. 2. The prevalences of atrial fibrillation and atherosclerosis related diseases were significantly higher in the elderly group. But there was no significant difference between the groups in smoking, hypertension, diabetes mellitus and hyperlipidaemia. Conclusion:For elderly ischemic colitis patients, the clinical manifestations are more typical and serious. The mortality rate is higher. Atrial fibrillation and atherosclerosis related diseases are the risk factors of ischemic colitis in the elderly.
