Endometrial ablation; less is more? Historical cohort study comparing long-term outcomes from two time periods and two treatment modalities for 854 women.

Background: Abnormal uterine bleeding needs surgical treatment if medical therapy fails. After introduction of non-hysteroscopic endometrial ablation as alternative to hysteroscopic endometrial resection, we aimed to compare short and long-term outcomes for women treated with these two minimally-invasive procedures. A secondary goal was comparing the present cohort to a previous cohort of women treated with hysteroscopic resection only.
