Objective To investigate the influencing factors of pregnancy outcomes after transcervical resection of polyp(TCRP)in infertility patients.Methods The data of 442 patients with infertility complicated with endometrial polyp(EP)underwent TCRP from March 2021 to March 2022 were retrospectively analyzed,and the postoperative follow-up time was 12-24 months,and they were divided into postoperative pregnancy group(pregnancy group)and non-pregnant group(control group).The two groups were compared with age,body mass index(BMI),infertility type,abnormal uterine bleeding,adverse pregnancy history,number of EP,EP size,intraoperative negative pressure uterine aspiration,endometritis,TCRP operation time,and uterine cavity depth,and multivariate analysis was conducted on the influencing factors of pregnancy outcomes after TCRP in infertility patients.Results Among 442 infertility patients with EP,274 cases(62.0%)were in the pregnancy group and 168 cases(38%)in the control group.The factors influencing pregnancy after TCRP were age(OR=0.925,95%CI:0.881-0.972,P<0.05),abnormal uterine bleeding before surgery(OR=0.646,95%CI:0.432-0.967,P<0.05)and primary infertility(OR=2.105,95%CI:1.295-3.423,P<0.05).Conclusion TCRP can improve pregnancy outcomes in infertility patients with EP.Age and abnormal uterine bleeding before operation were the protective factors to increase pregnancy after TCRP in infertility patients.Primary infertility is a risk factor for pregnancy after TCRP in infertility patients.
