Analysis of 3 cases in lower gastrointestinal bleeding caused by colon telangiectasia

目的探讨结肠毛细血管扩张症致下消化道出血的诊断和治疗。方法回顾性分析2010年9月-2015年1月该院收治的3例结肠血管扩张症致下消化道出血患者的临床资料。结果 3例患者均诊断为结肠毛细血管扩张症,其中2例累及全结肠,1例累及降、乙状结肠。1例患者经内镜下氩离子凝固术（APC）治疗,2例患者经药物保守治疗后均未再出现便血现象,大便潜血逐渐转为阴性。随访3个月~1年,未再出血。结论结肠毛细血管扩张症主要表现为下消化道出血和贫血,老年患者多见,出现不明原因的消化道出血需考虑该病,电子结肠镜是诊断该病的主要方法,药物治疗、内镜治疗或外科手术治疗均是该病的有效治疗方式。
