Abstract: Objective: To explore the effect of transcervical resection by hysteroscopy in the management of endometrial polyps and influencing factors in pregnancy. Methods: Sixty infertile patients due to endometrial polyps treated in our hospital from February 2013 to November 2014 were collected as research object. All patients were treated with hysteroscopic resection. 3 months, 6 months and 18 months of follow-up were made. The incidence rates of abnormal vaginal bleeding, recurrence rates, and spontaneous pregnancy rates were counted. Influence factors in spontaneous pregnancy rate of patients with endometrial polyps underwent transcervical resection were analyzed. Results: After surgery, the incidence rate of abnormal vaginal bleeding was 3.33%. The recurrence rate was 1.67%. Three months after surgery, the accumulated spontaneous pregnancy rate was 28.33%. Six months after surgery, the accumulated spontaneous pregnancy rate was 50.00%. Eighteen months after surgery, the accumulated spontaneous pregnancy rate was 65.00%. Single factor analysis showed the difference of spontaneous pregnancy rate of patients underwent surgery between ages was statistically significant(P＜0.01), the difference of spontaneous pregnancy rate of patients underwent surgery between duration of infertility, the kind of infertility, and polyp size were not statistically significant(P＞0.05). Logistic regression analysis showed age＞30 was the influence factor in spontaneous pregnancy rate of patients with endometrial polyps underwent transcervical resection (OR=11.00, 95%CI: 4.108-29.454, P=0.000). However, primary infertility, duration of infertility＞3 years, polyp size＞1 cm or more polyps did not influence spontaneous pregnancy of patients underwent surgery (P＞0.05). Conclusions: For infertile patients due to endometrial polyps, the hysteroscopic resection treatment had good therapeutic effect. The younger the age, the higher the spontaneous pregnancy rate after hysteroscopic surgery.
