电子阴道镜在宫颈癌前病变诊断中的临床价值

Clinical evaluation of electronic colposecopy in the diagnosis of cervical intraepithelial neoplasia

目的:探讨阴道镜下常规活检对宫颈上皮内瘤样病变(CIN)的检出率及阴道镜图像特征和诊断价值。方法:对300例宫颈病变患者中的44例CIN患者的阴道镜检查结果进行回顾性分析。结果:300例患者中发现CIN44例,占14.66%;CIN的异常图像为宫颈湿疣、醋白上皮、二联征、三联征,共占93.19%,不满意征象3例,占6.81%;阴道镜检查CIN,阳性预测值为75.86%、敏感性为93.62%、特异性为94.47%。结论:阴道镜检查是诊断CIN的重要方法,初次阴道镜检查可疑时应进行常规活检。

Objective：To investigate the incidence of cervical intraepithelial neoplasia（CIN）colposcopic findings and diagnostic value by routine biopsy under colposcopy. Methods：44 out of 300 cases between March and September 2006 in our hospital were diagnosed as CIN by routine biopsies under colposcopy were analyzed retrospectively. Results： The incidence of CIN diagnosed by routine biopsy was 14.66 % （44/300）. 93.19% the major colposcopi Findings were of condyloma acuminate, acetowhite epitheliam, twin signs and triple signs . Only 3 cases （6.81%） was of unsatisfactory colposcopic findings. Conclusions：Colposcopy is an important assitant method for diagnosis CIN,The initial colposcopy should include routine cervical biopsics.
