不同超声检查对直肠乙状结肠深部浸润型子宫内膜异位症诊断价值的Meta分析

Ultrasound value in diagnosis of deep infiltrating endometriosis in rectosigmoid:Meta-analysis

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 sdected 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 ETVS, 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. Conclu- sion 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.
