经阴道超声检查在深部浸润型子宫内膜异位症中的诊断意义

The value of transvaginal ultrasound in diagnostic of deep infiltrated endometriosis

目的探讨经阴道超声检查在深部浸润型子宫内膜异位症(DIE)中的诊断意义。方法收集2014年1月至2017年12月就诊于本院经阴道超声检查诊断为DIE并行腹腔镜手术治疗的患者108例,回顾性分析将超声检查结果与手术及病理结果相对照,评估经阴道超声检查对诊断DIE的敏感性及特异性。结果经阴道超声检查诊断为DIE患者共108例,共115处DIE病灶,其中经腹腔镜检查及病理诊断证实为DIE的患者共89例,95处DIE病灶,不同部位的DIE病灶超声诊断准确性有所不同,经阴道超声检查诊断DIE的准确性为82.6%,敏感性为82.1%、特异性为91.6%,阳性预测值为67.8%、阴性预测值为96.0%。结论阴道超声检查做为DIE手术前的一线检查可以为临床医师提供更好的帮助。

Objective To evaluate the value of transvaginal ultrasonography in diagnosis of deep Infiltrating endometriosis(DIE).Methods A total of 108 cases of DIE diagnosed by transvaginal ultrasonography and received laparoscopic surgery were collected in Peking University Third Hospital from January 2014 to December 2017.The sensitivity and specificity of transvaginal ultrasonography in the diagnosis of DIE were evaluated by comparing the results of ultrasonography with those of surgery and pathology.Results 115 locations were found among 108 cases.89 cases of DIE and 95 locations were diagnosed by laparoscopy and pathological diagnosis.The accuracy of diagnosis varied among different locations of DIE.The accuracy,sensitivity and specificity of transvaginal ultrasonography in the diagnosis of DIE was 82.6%,82.1%and 91.6%respectively,positive and negative predictive values were 67.8%and 96.0%.Conclusion The transvaginal ultrasonography could provide an effective and practical first-line examination before the operation for DIE.
