Abstract To analyze the influence of hysteroscopic endometrial polypectomy for treating infertility patients with endometrial polyps on their pregnancy outcomes within two years after surgery, and to analyze their related factors. Methods: The clinical data of 90 infertility patients who underwent hysteroscopic endometrial polypectomy from January 2015 to January 2019 were analyzed retrospectively. The patients were followed up for 2 years after operation. The natural pregnancy rate and the pregnancy outcomes of these patients were counted, and the pregnancy outcomes-related factors of the natural pregnancy of these patients were analyzed. Results: There were 20 patients with natural pregnancy, 4 patients with abortion, and 3 patients with premature birth within 1 year after operation. There were 41 patients with natural pregnancy, 7 patients with abortion, and 6 patients with premature birth within 2 years after operation. The total pregnancy rate of the patients within 2 years after operation was 67.8% (61/90), which included 67.2% (41/61) of normal delivery rate and 32.8% (20/61) of adverse pregnancy outcomes rate. There were significant differences in the age, the body mass index, the diameter, number, and location of endometrial polyp, the abortion history, and the endometrial polyp recurrence between the patients with normal delivery and the patients with adverse pregnancy outcomes (P＜0.05). There were no significant differences in the duration of polyp course, the duration of infertility, the diabetes history, the hypertension history, and the uterine cavity surgery history between the patients with normal delivery and the patients with adverse pregnancy outcomes (P＞0.05). Logistic regression analysis model showed that the advanced age, the high value of body mass index, the larger diameter and more number of polyps, the polyps in the corner and posterior wall of the uterus, and the history of abortion were the independent risk factors of the adverse pregnancy outcomes of the patients after hysteroscopic endometrial polypectomy (P＜0.05). Conclusion: Both the pregnancy rate and the pregnancy outcomes of the infertility patients with endometrial polyps within two years after hysteroscopic endometrial polypectomy are ideal, and the age, the value of body mass index, the diameter, number, and location of the polyps, the history of abortion of the patients are all the factors affecting their pregnancy outcomes after operation, which should be paid attention to in clinic.
