Prediction of menstrual patterns and analysis of adverse effects for hysteroscopic endometrial polypectomy combined with LNG-IUS treatment: a single-center retrospective cohort study

Hysteroscopic polypectomy combined with LNG-IUS insertion was an effective measure to treat endometrial polyps. LNG-IUS intraoperative placement did not increase the incidence of adverse reactions. Preoperative endometrial thickness and maximum polyp diameter play a key role in valuable prediction for the duration of irregular uterine bleeding after LNG-IUS insertion.
