目的:探讨宫颈癌与宫颈病变筛查中阴道镜的临床应用。方法:将500例宫颈病变患者作为观察对象,所有患者均采用阴道镜进行检查,分析检查结果。结果:在阴道镜下异常图像的种类相对较多;病变级别越高,醋白上皮的厚度就越厚,透明度就越差,其消失的时间就越长,点状血管就越粗。结论:阴道镜可以提高宫颈上皮内瘤样病变(CIN)的检出率,在宫颈癌与宫颈病变筛查中有着很高的应用价值。 Objective: To investigate the clinical application of colposcopy in the screening of cervical cancer and cervical lesions. Methods: 500 cases of cervical lesions as the observation object, all patients were colposcopy examination, analysis of test results. Results: The types of abnormal images under colposcopy were relatively more. The higher the lesion level was, the thicker the vinegar white epithelium was and the worse the transparency was. The longer it disappeared, the thicker the punctate vessels. Conclusion: Colposcopy can improve the detection rate of cervical intraepithelial neoplasia (CIN), which has a high value in screening cervical cancer and cervical lesions.
