阴道镜检查在子宫颈病变中的诊断价值附2716例报告

目的通过阴道镜检查图像分析及定位活检结果,评价电子阴道镜检查在子宫颈病变诊治中价值及应用.方法回顾分析我院子宫颈病变阴道镜检查2716例,行镜下定位取活组织病理检查.评价阴道镜检查的效能,计算子宫颈疾病的构成比.结果阴道镜检查诊断子宫颈病变的敏感性87.7%,特异性66.4%,符合率81.1%,阳性预测值85.3%,宫颈病变阴道镜检查疾病构成比中,子宫颈上皮内瘤病变占28.5%,子宫颈癌占4.3%.高级别宫颈上皮内瘤样病变组醋白上皮、镶嵌、异型血管发生率显著高于低级别组.结论阴道镜检查因其敏感性及阳性预测值高,并能指导图像明显异常部位选择性的定位活检,对诊断宫颈上皮内瘤样病变有重要价值.

Evaluation of Colposcopy in the Diagnosis of Cervical Diseases-2716 Cases Report

Objective To evaluate the value of colpscopy in the diagnosis of cervical diseases.Method Colposcopic inspections and biopsies were performed on 2716 women in our hospital.The efficacy of colposcopy was evaluated and the ratio of cervical diseases was caiculated.Result The sensitivity,specificity,coincidence,and positive predictive value（PPV） of colpscopy in the diagnosis of cervical lesion was 87.7%,66.4%,81.1%,and 85.3% respectively.The proportion of the cervical intraepithelial neoplasia was 28.5%.The cervical cancer was 4.3%.The incidence of acetowhite epithelium,mosaic,atypical vessels in the case of high CIN was significantly higher than the lower CIN.Conclusion Because colposcopy has the high sensitivity and positive predictive value（PPV） and can find the microlesion on the cervix and help to conduct directly elective locational biopsy,it has great value in the diagnosis of cervical intraepithelial neoplasia.
