Analysis of the effect of cervical conization through cervical endoscopy in the treatment of High-grade cervical intraepithelial neoplasia

Abstract

Objective To investigate the clinical effect of cervical conization under cervical endoscopy in high-grade cervical intraepithelial neoplasia (CIN). Methods From June 2017 to June 2019, 100 patients with grade II and III CIN admitted to Harbin First Hospital were divided into control group and observation group with 50 cases in each group by random number table method.The control group was treated with traditional cervical cold knife conization, while the observation group was treated with cervical conization under endoscopy.To compare the therapeutic effects of two surgical methods. Results The incidence of positive margin were significantly lower than that in the control group(8%(4/50) and 18%(9/50)), and the difference was statistically significant (χ2=4.98, P 0.05). Conclusion The cervical conization through cervical canal endoscope can accurately locate the focus of high-grade CIN, with higher rate of lesion clearance, lower rate of lesion recurrence and complications.
