目的探讨电子阴道镜在临床诊断宫颈癌中的应用价值。方法将我院收治的240例疑似宫颈癌患者,随机分为对照组和观察组,每组各120例,对照组采用宫颈巴氏细胞学诊断,观察组采用电子阴道镜诊断,并与病理学检查结果比较,分析两种诊断方法的敏感度、特异度、阳性预测值。结果电子阴道镜检查总阴性数76例,阳性数44例,宫颈上皮内瘤样变Ⅰ级20例,宫颈上皮内瘤变Ⅰ～Ⅱ级12例,宫颈上皮内瘤样变Ⅱ～Ⅲ级12例。以病理学诊断为金标准,电子阴道镜检查敏感度为96.1%,特异度为88.3%,阳性预测值为80.3%,漏诊率为6.2%。结论电子阴道镜可在一定程度上提高宫颈癌前期病变检出率,降低假阳性率及假阴性率,是一种简单易行,可重复使用,利于随访的检查方法,值得临床推广应用。
Objective To investigate the clinical value of electronic colposcopy in the diagnosis of cervical cancer. Methods 240 cases of suspected cervical cancer admitted to our hospital were randomly divided into control group and observation group, 120 cases in each group. The control group was diagnosed by Papanicolaou cervix. The observation group was diagnosed by electronic colposcopy and was associated with pathology Comparison of test results, analysis of the sensitivity of the two diagnostic methods, specificity, positive predictive value. Results The total number of negative colposcopy in 76 cases, the positive number of 44 cases, cervical intraepithelial neoplasia grade Ⅰ in 20 cases, cervical intraepithelial neoplasia Ⅰ ~ Ⅱ grade in 12 cases, cervical intraepithelial neoplasia grade Ⅱ ~ Ⅲ 12 example. Pathological diagnosis as the gold standard, electronic colposcopy sensitivity was 96.1%, specificity was 88.3%, positive predictive value was 80.3%, missed diagnosis rate was 6.2%. Conclusions Electronic colposcopy can improve the detection rate of cervical precancerous lesions to a certain extent, reduce the false positive rate and false negative rate, which is a simple, reusable and conducive follow-up examination method, worthy of clinical application.
