经腹与经阴道超声诊断异位妊娠符合率的Meta分析

目的: 应用荟萃 （Meta） 分析探讨经腹超声与经阴道超声对异位妊娠诊断符合率。方法: 采用Review Manager 4.2软件, 应用Meta分析固定效应模型和随机效应模型对1995年1月—2008年12月国内外有关经腹与经阴道超声诊断异位妊娠符合率的研究进行综合定量评价。结果: 经筛选并纳入本次Meta分析的文献共22篇。累计经阴道超声组2 010例,经腹超声组2 015例,RR随机值为1.37（95% CI 1.24～1.52）,差别有统计学意义（P <0.000 01）。结论: 经阴道超声诊断异位妊娠优于经腹超声,有条件的单位应将经阴道超声作为诊断异位妊娠的首选方法。

Meta-analysis for the Accuracy of Transabdominal Versus Transvaginal Sonography in the Diagnosis of Ectopic Pregnancy

Objective：To assess the accuracy of transabdominal sonography （TAS） and transvaginal sonography（TVS） in the diagnosis of ectopic pregnancy by meta-analysis. Methods：Literatures about transabdominal sonography（TAS） versus transvaginal sonography（TVS） in patients with ectopic pregnancy issued from January 1995 to December 2008 were retrieved and the effects were quantitatively estimated with fixed-effect model and random-effect model by meta-analysis. Results：In 22 trials, the diagnose accordance rate between TVS and TAS is significant, with the pooled RR 1.37（95% CI 1.24～1.52）. Conclusions：TVS was better in the diagnosis of ectopic pregnancy than TAS.
