The application of endometrial ablation (EA) has significantly increased in the past 10 years. It is an effective treatment for heavy menstrual bleeding with functional aetiology. However, the risk of post-ablative intracavitary scarring after EA is significant and can lead to long term complications, and the possible delay in diagnosing endometrial cancer. CLEAN is a prospective, multi-center, randomized, controlled, two arm pilot clinical trial. The objective is to compare the formation of adhesions after third-generation endometrial ablation, with and without the intrauterine adhesion barrier.~The study will be performed on women with heavy menstrual bleeding (menorrhagia) scheduled for thermal endometrial ablation with Novasure system (Hologic) A follow-up diagnostic hysteroscopy will be performed 4-8 weeks after the ablation procedure to determine the presence and severity of IUAs according to the American Fertility Society.
Evaluate the formation of adhesions after third-generation endometrial ablation, with and without the intrauterine adhesion barrier.
