目的探讨阴道镜诊断子宫颈病变尤其是宫颈上皮内瘤变的准确性及影响因素。方法2007年7月至2008年7月期间本院利用阴道镜检查对子宫颈病变检查,同时行阴道镜下定位取病检,以组织学诊断作为对照进行结果分析。结果阴道镜检查定位活检691例,599例阴道镜诊断同病理诊断完全符合,准确率86.7%。阴道镜检测出宫颈上皮瘤样病变的灵敏度为91.0%,特异度86.3%。阴道镜与病理组织学结果一致性检验,Kappa值为0.79,χ2检验P<0.01,认为两种诊断方法具有一致性。结论阴道镜诊断的准确性保证了宫颈疾病的正确诊断和宫颈癌的筛查程序。
Objective To investigate the accuracy and influencing factors of colposcopy in the diagnosis of cervical lesions, especially cervical intraepithelial neoplasia. Methods From July 2007 to July 2008, our hospital used colposcopy to examine the cervical lesions. At the same time, colposcopy was performed to take the pathological examination, and histological diagnosis was used as the control to analyze the results. Results colposcopy positioning biopsy 691 cases, 599 cases of colposcopy diagnosis with pathological diagnosis in full compliance with an accuracy rate of 86.7%. Colposcopy detection of cervical epithelial tumor-like lesions of sensitivity was 91.0%, specificity of 86.3%. Colposcopy and histopathological consistency test, Kappa value of 0.79, 2 test P <0.01, that the two diagnostic methods are consistent. Conclusion The accuracy of colposcopy diagnosis ensures the correct diagnosis of cervical disease and cervical cancer screening program.
