The clinical value of high frequency electrotome conization in the treatment of high-grade cervical intraepithelial neoplasia

Objective: To evaluate the clinical value of high frequency electrotome conization in the treatment of high-grade cervical intraepithelial neoplasia.Methods: One hundred and seventy-two HSIL patients treated with high frequency electrotome conization and 42 HSIL patients treated with cervical loop electrosurgical excision procedure(LEEP) were divided into the observation group and control group,respectively.The intraoperative hemorrhage,postoperative hemorrhage,operation time,postoperative infection rate,postoperative cervical canal adhesion rate,positive incisal margin rate and recurrence rate in two groups were observed.Results: The difference of the operation time between the observation group(21.02±1.81) min and control group(21.57±1.48) min was not statistically significant(P>0.05).The intraoperative blood loss in observation group(13.61±2.39) mL was higher than that in control group(12.60±2.08) mL(P<0.05).The positive incisal margin rate and recurrence rate in observation group(1.74% and 1.59%) were lower than those in control group(9.52% and 10.81%),respectively(P<0.05).The differences of the postoperative infection rate and postoperative cervical canal adhesion rate between two groups were not statistically significant(P>0.05).Conclusions: High frequency electrotome conization is easy to operate,and the peroperative bleeding,operation time and postoperative complication of which do not obviously improve compared with LEEP.The positive incisal margin rate and recurrence rate of high frequency electrotome conization are better than those of LEEP,and the high frequency electrotome conization can be the prior method in the treatment of cervical intraepithelial neoplasia.
