Observation on the curative effect of small ring electrode assisted LEEP of cervix in treatment of cervical erosion with cervical inflammation

Objective To investigate the effect of small annular electrode assisted electrosurgical excision of cervical canal mucosa on cervical loop electrosurgical excision procedure (LEEP) in patients with cervical erosion and endocervicitis. Methods From March 2016 to March 2017, one hundred and twenty cases with cervical erosion treated in the Third People′s Hospital of Shenzhen were selected and were randomly divided into the control group and the observation group, with 60 cases in each group.The patients in the control group were treated with conical or LEEP while patients in the observation group were treated by putting the small ring electrode into the cervical canal under 0.4 ~ 0.6 cm longitudinal resection to treat cervical inflammatory lesions based on the treatment of the control group.The postoperative and postoperative recovery, postoperative efficacy and complications of the two groups were compared. Results There was no statistical significance between the observation group and the control group in the time of operation, the amount of bleeding during operation, and the time of vaginal drainage after operation (P>0.05). The curative rate of the observation group and the control group were 75.0%(45/60) and 51.7%(31/60) at 1 month after operation respectively, and they were 95.0% (57/60) and 70.0% (42/60) at 2 months after operation.The difference was statistically significant (P<0.05). The incidence of eversion of cervical columnar epithelium in the observation group and the control group were 5.0% (3/60) and 18.3% (11/60) at 1 month after the operation, and the difference was statistically significant (χ2=12.4, P<0.05). The incidence of eversion of cervical columnar epithelium in the observation group and the control group were 3.3% (2/60) and 13.3% (8/60) at 2 months after the operation, and the difference was statistically significant (χ2=9.51, P<0.05). No cervical laxity and stenosis occurred in both groups at 6 months after the operation. Conclusion The LEEP modified by small annular electrode can effectively improve the curative rate of cervical erosion in patients with endocervicitis, reduce the incidence of cervical columnar eversion, and does not prolong the operation time and does not increase the risk of bleeding or affect postoperative uterine function, which has good clinical value.
