目的探讨电子阴道镜在宫颈疾病诊断中的应用价值。方法收集华北煤炭医学院附属唐山市中医院妇产科2001～2004年240例宫颈疾病患者进行阴道镜检查并行宫颈活组织检查结果,进行回顾性分析和比较。结果(1)电子阴道镜在诊断宫颈病变中敏感度为80.4%,特异度为87.8%,假阴性率(漏诊率)为4.3%,阳性预测值为83.9%。(2)阴道镜图像与组织学结果相比:醋白上皮符合率为66.7%,二联征符合率为77.8%,三联征符合率100%,可疑宫颈癌符合率100%。(3)宫颈疾病以30～39岁发病者所占比例最大(46.5%)。结论电子阴道镜检查技术诊断宫颈疾病结果准确可靠,有一定的应用价值,特别对CIN的早期诊断、早期治疗及降低宫颈癌的发生率有重要价值。
Objective To explore the value of electronic colposcopy in the diagnosis of cervical diseases. Methods Collected colposcopy and cervical biopsy in 240 obstetrics and gynecology department of Tangshan Hospital of Traditional Chinese Medicine Affiliated to North China Coal Medical College from 2001 to 2004 and retrospectively analyzed and compared. Results (1) The electronic colposcopy in the diagnosis of cervical lesions sensitivity was 80.4%, specificity was 87.8%, false negative rate (misdiagnosis rate) was 4.3%, the positive predictive value was 83.9%. (2) Compared with histological results, the coincidence rate of colloidal white epithelium was 66.7%, the coincident rate of two sign was 77.8%, the coincidence rate of triple sign was 100% and the coincidence rate of suspected cervical cancer was 100%. (3) The incidence of cervical diseases in 30 to 39 years old the largest proportion (46.5%). Conclusion The results of electronic colposcopy in diagnosing cervical diseases are accurate and reliable, and have certain value in application. In particular, it is of great value in the early diagnosis, early treatment of CIN and the incidence of cervical cancer.
