目的探讨阴道镜在三阶梯宫颈癌筛查中的应用价值。方法对160例经LEEP术后病理结果证实为CIN2-3患者的阴道镜检查情况及宫颈点活检结果的准确性作自身对照研究。结果阴道镜下活检与LEEP术后病理结果相符合的有106例,占66.25%;其中宫颈为Ⅰ型转化区的诊断符合率为77.89%;转化区为Ⅱ、Ⅲ型的诊断符合率为37.50%,差异具有统计学意义(P<0.05)。结论在宫颈癌前病变的筛查中应根据阴道镜下评估的转化区类型决定活检方式,如果属Ⅱ、Ⅲ型转化区建议直接用诊断性LEEP术或宫颈管搔刮术以排除宫颈管内病变。
Objective To explore the value of colposcopy in the screening of three-stage cervical cancer. Methods 160 cases of postoperative pathological results by LEEP confirmed CIN2-3 patients colposcopy and cervical biopsy results of the accuracy of self-control study. Results Colposcopy biopsy and LEEP postoperative pathological findings in 106 cases, accounting for 66.25%; cervical type Ⅰ transformation zone diagnostic accuracy was 77.89%; transformation zone Ⅱ, Ⅲ type diagnostic accordance rate was 37.50 %, The difference was statistically significant (P <0.05). Conclusion In the screening of precancerous lesions of cervix, the biopsy method should be decided according to the type of transformation zone assessed by colposcopy. If it is a type II or type III transformation area, it is recommended to use direct diagnostic LEEP or endocervical curettage to rule out cervical canal lesions .
