目的 采用Meta分析评价经阴道增强超声(E-TVS)、经阴道超声(TVS)、经直肠超声(TRS)对直肠乙状结肠深部浸润型子宫内膜异位症的诊断价值.方法 检索1990年1月-2016年6月关于E-TVS、TVS、TRS诊断直肠乙状结肠深部浸润型子宫内膜异位症(DIE)的中英文文献,提取纳入研究的信息,采用Meta-disc 1.4软件对研究数据进行统计学分析.结果共纳入25篇英文文献.E-TVS的敏感度、特异度、阳性似然比、阴性似然比、诊断性比值比分别为0.92、0.96、16.64、0.09、227.95;TVS为0.83、0.97、16.95、0.17、112.97;TRS为0.94、0.96、14.43、0.08、208.72.3组SROC曲线下面积分别为0.980 4、0.966 3、0.979 0.结论 3种超声检查方法对直肠乙状结肠DIE的诊断价值由高至低依次为E-TVS、TRS、TVS.E-TVS可作为超声诊断直肠乙状结肠DIE的首选方法.
Objective To explore the diagnostic value of comparing enhanced transvaginal ultrasound (E-TVS),none enhanced transvaginal ultrasound (TVS),and transrectal ultrasound (TRS) in preoperative detection of deep infiltrating endometriosis (DIE) in the rectosigmoid by Meta-analysis.Methods The literatures published from January 1990 to June 2016 were searched.The information of literatures were selected and evaluated.The included data was statistically analyzed by Meta-disc 1.4 software.Results Totally 25 literatures were enrolled.The pooled sensitivity,specificity,positive likelihood ratio,negative likelihood ratio,diagnostic odds ratio were 0.92,0.96,16.64,0.09,227.95 for E-TVS,0.83,0.97,16.95,0.17,112.97 for TVS,0.94,0.96,14.43,0.08,208.72 for TRS,respectively.Area under the curve were 0.980 4,0.966 3,0.979 0,respectively.Conclusion Diagnostic value of the three ultrasonography in preoperative detection of DIE in the rectosigmoid are E-TVS,TRS,TVS.E-TVS can be used as the preferred method of ultrasonic diagnosis of DIE in the rectosigmoid.
