目的:评价电子阴道镜定位活检对宫颈上皮内瘤变的诊断价值。方法:442例经宫颈薄层液基细胞学(TCT)检查结果为鳞状细胞异常的妇女,采用电子阴道镜检查并定位活检的330例为观察组;肉眼下活检的112例为对照组。最终以病理组织学诊断为金标准,对比两组病理组织学诊断阳性符合率,同时评价阴道镜检查对宫颈上皮内瘤变的诊断效能。结果:观察组330例患者中病理组织学诊断为慢性宫颈炎174例、宫颈上皮内瘤变142例、宫颈癌14例,阳性符合率为47.3%;对照组阳性符合率为9.8%,两组诊断符合率比较差异有统计学意义(P<0.01)。结论:采用电子阴道镜活检能显著提高宫颈上皮内瘤变的阳性检出率,为防治宫颈癌提供有效依据。
Objective: To evaluate the diagnostic value of electronic colposcopy biopsy for cervical intraepithelial neoplasia. Methods: A total of 442 women with squamous cell abnormalities who underwent LCT (cytology-based cytology) were examined by electron colposcopy and biopsy. One hundred and fourty-two patients undergoing biopsy were selected as the control group. Finally, the histopathological diagnosis as the gold standard, histopathological diagnosis of the two groups compared with the positive rate, and evaluate the colposcopic examination of cervical intraepithelial neoplasia diagnostic efficacy. Results: Among the 330 patients in the observation group, there were 174 cases of chronic cervicitis, 142 cases of cervical intraepithelial neoplasia and 14 cases of cervical cancer, the positive coincidence rate was 47.3%. The positive coincidence rate of the control group was 9.8% The diagnostic coincidence rate was significantly different (P <0.01). Conclusion: The electronic colposcopy biopsy can significantly improve the positive rate of cervical intraepithelial neoplasia, to provide an effective basis for the prevention and treatment of cervical cancer.
