Objective To investigate the value and significance of the cervical biopsy with the electronic colposcopy for the diagnosis of cervical lesions in clinical practice.Methods The datum of 126 patients from January 2011 to December 2012 in Ruici Hospital in Nantong City were analyzed.All patients were received examined with electronic colposcopy and the results of diagnosis by electronic colposcopy were compared with the pathological examination.Results Of all these patients,chronic cervicitis was 67,cervical intraepithelial neoplasia(CIN)was 51 and 8 cases of cervical cancer,who were diagnosed with the electronic colposcopy.But with the pathological examination,cervicitis were 76 cases,CIN were 45 cases,5 cases of cervical cancer.Diagnosis rate were 89.5％,88.2％ and 62.5％,respectively.Conclusion The examination and localized biopsy by the colposcopy can be used for early diagnosis and improve the detection rate of cervical lesions in order to early diagnose and treat for reducing the incidence of advanced cervical cancer significantly.%目的 探讨电子阴道镜下定位活检在宫颈病变诊断中的临床应用价值.方法 选取2011年1月～2012年10月在江苏省南通市瑞慈医院妇产科行阴道镜检查的患者126例进行回顾性分析,所有患者均行电子阴道镜检查,并与宫颈活检组织病理学检查结果作为对照.结果 阴道镜图像诊断为慢性宫颈炎67例,宫颈上皮内瘤变(cervical intra-epithelial neoplasia,CIN)51例,宫颈癌8例；病理检查宫颈炎76例,CIN 45例,宫颈癌5例.诊断符合率达到89.5％,88.2％和62.5％.结论 电子阴道镜定位下活检具有创伤小、准确性高等优点,在CIN及宫颈癌的早期诊断中具有重要意义.
