目的 :为总结宫颈上皮内瘤样病变 (CIN)近年发生情况 ,并对其筛查诊断方法进行比较分析。方法 :总结1993年 1月～ 1999年 12月行阴道镜检查、宫颈活体组织检查的 92 7例病人 ,分析近年来 CIN检出情况及宫颈涂片细胞学和阴道镜检查对其筛查诊断的意义。结果 :宫颈涂片细胞学人工阅片筛查的敏感度为 41.2 % ,电脑辅助细胞学分析系统 (CCT)筛查的敏感度 75 .6 % ,阴道镜诊断的敏感度为 94.9%。结论 :近年来 CIN发病有明显增加趋势。宫颈涂片细胞学筛查 CIN的敏感度有待提高 ;对非典型细胞 (ASCCUS)应予以重视。阴道镜指导下宫颈活组织检查是诊断 CIN的敏感方法
Objective: To summarize the incidence of cervical intraepithelial neoplasia (CIN) in recent years, and to compare the screening diagnostic methods. Methods: From January 1993 to December 1999, 927 patients underwent colposcopy and cervical biopsy were analyzed. The detection of CIN in recent years and the diagnosis of cervical smear cytology and colposcopy were analyzed significance. Results: The sensitivity of cervical smear cytology screening was 41.2%, the sensitivity of screening by computer assisted cytological analysis (CCT) was 75.6%, and the sensitivity of colposcopy was 94.9%. Conclusion: The incidence of CIN increased significantly in recent years. Cervical smear cytology screening sensitivity of CIN needs to be improved; atypical cells (ASCCUS) should be valued. Cervical biopsy under the guidance of colposcopy is a sensitive method for the diagnosis of CIN
