简介:目的探讨Dieulafoy病的诊断与治疗。方法对近年来15例Dieulafoy病临床和内镜资料进行分析。结果内镜治疗7例,其中注射高渗盐水或硬化剂5例,射频治疗2例,均立即止血,其中l例再次出血死亡。手术7例,均治愈。结论内镜治疗是Dieulafoy病主要治疗方法,其中射频治疗效果尚属满意,但需进一步观察总结经验。手术治疗可彻底解决血管畸形问题,仍为重要治疗手段。

简介:目的了解我国内镜治疗的临床科研现状。方法逐期逐页手工检索《中华消化内镜杂志》(1984~2002年)及《中国内镜杂志》(1996~2002年)中发表的临床对照实验,按cochrane协作网RCF、CCT资料库中的判定标准进行严格评价。结果《中华消化内镜杂志》19卷87期中共刊临床性文章1196篇,其中RCTs85篇(7.17%),CCTs4篇(0.34%)。《中国内镜杂志》7卷37期中共刊临床性文章1122篇,其中RCTs51篇(4.54%),CCTs6篇(0.53%)。结论我国临床内镜治疗的防治性研究RCTs的数量和质量,还不能满足临床实践的需要。
