目的探讨阴道镜定位下活检对宫颈上皮内瘤变(CIN)的诊断价值。方法 2008年1月至2009年12月对200例行阴道镜下宫颈活检诊断为CIN患者,行宫颈环形电切术(LEEP术),将术后病理结果与活检病理结果进行比较,分析两者的符合程度,判断阴道镜下定位活检在宫颈上皮内瘤变诊断中的应用价值。结果以LEEP术后病理为标准,阴道镜下宫颈活检病理结果符合率为87.00%;不符合率为13.00%,其中诊断过度6.00%,诊断不足7.00%。结论阴道镜下定位活检可发现宫颈微小病灶,诊断准确性高,损伤小,漏诊率低,是诊断CIN的可靠方法。
Objective To investigate the diagnostic value of colposcopic biopsy for cervical intraepithelial neoplasia (CIN). Methods From January 2008 to December 2009, 200 patients with CIN underwent colposcopic biopsy under cervical colposcopy were treated with LEEP. The pathological results were compared with the biopsy results. Of the degree of coincidence, to determine colposcopy positioning biopsy in the diagnosis of cervical intraepithelial neoplasia in the value. Results According to LEEP postoperative pathology, the coincidence rate of colposcopic biopsy pathology was 87.00%; the rate of non-coincidence was 13.00%, of which 6.00% was diagnosed and the diagnosis was less than 7.00%. Conclusions Colposcopic localization biopsy can detect tiny cervical lesions with high diagnostic accuracy, small injury and low rate of missed diagnosis. It is a reliable method for the diagnosis of CIN.
