阴道镜检查对宫颈上皮内瘤变的诊断价值分析

目的探讨阴道镜在宫颈癌检查中,对宫颈上皮内瘤变的诊断价值。方法 2009年9月至2011年8月对896例TCT重度炎症及以上结果者行阴道镜检查,对182例阳性病例行阴道镜下定点活检,最终以组织学诊断为金标准,对结果进行回顾性分析、比较和总结。结果阴道镜诊断宫颈上皮内瘤变(CIN)的灵敏度为91.89%,特异度为93.79%,阴性预测值为97.84%,阳性预测值为79.07%。湿疣和SPI的敏感度为87.50%,特异度为96.67%,阴性预测值为97.32%,阳性预测值为84.85%。结论阴道镜在宫颈癌筛查中,对宫颈上皮内瘤变的诊断有重要价值,与TCT联合应用可以提高宫颈病变的诊断率,减少漏诊、误诊的发生。

The analysis of diagnostic value of colposcopy in cervical intraepithelial neoplasia

Objective To explore the diagnostic value of colposcopy in cervical intraepithelial neoplasia of screening for cervical cancer. Methods From September 2009 to August 2011, 896 cases with severe inflammation in TCT examination and above the result adopted colposeope examination, and 182 positive cases received location biopsy with colposcope, the histological diagnosis as the gold standard. Results The sensitivity for colposcopy diagnosis of CIN was 91.89%, the specificity was 93.79%, the negative predictive value was 97.84%, the positive predictive value was 79. 07%. The sensitivity of Condyloma and SPI was 87.50%, the specificity was 96.67%, the negative predictive value was 97. 32%, the positive predictive value was 84. 85%. Conclusions It is important of colposcopy in cervical intraepithelial neoplasia diagnosis, combining with TCT, it can improve the diagnostic rate of cervical disease, reduce the missed diagnosis and misdiagnosis.
