Study Of Factors Influencing Colposcopy In Diagnosis Of High-Grade Cervical Intraepithelial Lesions

Objective: To evaluate the coincidence rate of First Affiliated Hospital of Hebei North University colposcopy in the diagnosis of high-grade cervical intraepithelial lesions,and to analyze the factors associated with colposcopy in diagnosing HSIL overestimation and underestimation.Method: A retrospective study was used to select 512 cases of high grade cervical intraepithelial lesions diagnosed by colposcopy in the operation room of gynecologic outpatient operation room from September 2016 2016 to September 2017.Colpscopy biopsy was performed within three months after colposcopy in 512 patients.If the colposcopy biopsy result is<HSIL,the colposcopy is overdiagnosed.If the colposcopy biopsy result is≥HSIL,follow up operation will be performed within 6 months after biopsy.It includes Leep conization or cold knife conization or total hysterectomy.If the final diagnosis is diagnosed by colposcopy,if the final diagnosis is higher than that of the colposcopy,the final diagnosis is the final diagnosis.The final diagnosis was HSIL,indicating that the colposcopy diagnosis was accurate and the final diagnosis>HSIL.The 512 patients were divided into three groups,the same group: the final diagnosis was consistent with the colposcopy diagnosis of HSIL;the overestimated group: the colposcopy biopsy results<HSIL(mild stypical hyperplasia,inflammatory lesions and cervical intraepithelial low degree lesion);the underestimated group: final diagnosis > HSIL(ceivical aquamous and adenosscale squamous cell carcinoma).The clinical data of patients were collected and analyzed by statistical methods.Result: a total of 512 patients were eligible for inclusion in the study.There were 312 cases in the same group,and the accuracy rate of colposcopy was 60.94%.Over 163 cases were estimated,with an estimated excess rate of 31.84%,with an estimated underestimate of 37 cases,with an underestimated rate of 7.23%.Conclusion:1 The use of colposcopy can significantly improve the accuracy of the diagnosis of HSIL,but the accuracy of the diagnosis of the colposcopy is still affected by many fsctors,It may be inadequate and overestimated,and cervical curettage should be added when necessary.2 Cervical biopsy under colposcopy can improve the accuracy of diagnosis of HSIL,but patients with contact bleeding symptoms,TCT≥HSIL,and multiple biopsy should be vigilant for colposcopy diagnosis of HSIL,and may miss the diagnosis of cervical microinvasive carcinoma.3 Colposcopy diagnosis of HSIL,but patients TCT<HSIL,HPV negative,we should pay attention to the lack of estimation.
