Abstract:Objective To investigate the influence of LNG-IUS placement on endometrial thickness, recurrence rate and complications of patients with endometrial polyps and moderate anemia after TCRP. Methods 140 patients with endometrial polyps and moderate anemia were chosen from January 2014 to January 2016 and randomly divided into control group (70 patients) with TCRP used alone and observation group (70 patients) with LNG-IUS placement after TCRP; the endometrial thickness, hemoglobin levels and PBAC score before and after treatment, the recurrence rate and the complication incidence of both groups were compared. Results The endometrial thickness after treatment of observation group were significantly less than control group before the treatment (P < 0.05). The hemoglobin levels and PBAC score after treatment of observation group were significantly better than control group before the treatment (P < 0.05). The recurrence rate of observation group were significantly lower than control group (P < 0.05). There was no significant difference in the complication incidence between the two groups (P > 0.05). Conclusion LNG-IUS placement in treatment of patients with endometrial polyps and moderate anemia after TCRP can efficiently reduce the endometrial thickness, decrease the uterine bleeding amount, prevent the longterm recurrence and not increase the complications incidence.
