Abstract： 目的:探讨胶囊内镜诊断不明原因消化道出血(OGIB)的可靠性及根据其诊断结果指导疾病临床转归的有效性.方法:收集2002-05/2005-06间因不明原因消化道出血连续至本院行胶囊内镜检查的患者99例,通过就诊记录、电话追踪和门急诊随访等分析胶囊内镜诊断结果的临床符合情况、根据该诊断指导干预措施的结果、患者再出血及再检查等情况.结果:胶囊内镜对OGIB的病变检出率为89.9%,平均随访时间为18.4(6-41)mo,63例(63.6%)胶囊内镜检查结果得以验证,病变检出率在验证前后无显著差异(P=0.36),最终确诊率达90.5%(57/63).根据胶囊内镜诊断结果指导的特异性治疗率为50.5%(50/99),总成功率为82%(41/50),且经胶囊内镜诊断结果指导的对小肠阳性病变的有效干预率显著高于可疑阳性病变(P=0.01).结论:胶囊内镜诊断不明原因消化道出血的准确性高,能有效指导对疾病的进一步治疗,并能较大程度地影响这些疾病,特别是溃疡、肿瘤及血管发育不良所致的不明原因消化道出血的临床转归.
