Objective To investigate the clinical efficacy of hysteroscopic electrotomy in the treatment of abnormal uterine bleeding caused by endometrial polyps. Methods A total of 60 cases were studied with endometrial polyps, from December 2020 to December 2021, divided into reference group, study group, the reference group applied curettage treatment, and the study group applied hysteroscopic endometrial polyp electrotomy to compare the treatment effect. Results The intraoperative blood loss, operation time, ambulation time and hospital stay in the study group were all lower than those in the control group, P<0.05. The complication rate of the study group was lower than that of the reference group, P<0.05. The effective rate of treatment in the study group was higher than that in the reference group, P<0.05. The recurrence rate of the study group was lower than that of the reference group (P<0.05). The QOL score of the study group was significantly higher than that of the control group (P<0.05). Conclusion Hysteroscopic electrosurgical treatment for patients with abnormal uterine bleeding caused by endometrial polyps can reduce intraoperative blood loss, short operation time, fewer complications, shorten postoperative recovery time, and also effectively improve the treatment efficiency, reduce endometrial thickness, improve quality of life, with significant therapeutic effect, worthy of clinical promotion and application.
