Randomized Controlled Trial Comparative StudyRandomised comparative trial of thermal balloon ablation and levonorgestrel intrauterine system in patients with idiopathic menorrhagia.
To compare the effectiveness of thermal balloon ablation (TBA) and levonorgestrel intrauterine system (LNG-IUS) in the management of idiopathic menorrhagia and changes in pictorial blood loss assessment chart (PBAC) scores in patients who had failed on oral medical treatment. ⋯ Both TBA and LNG-IUS achieved significant decreases in PBAC scores, with those for the LNG-IUS being significantly greater at 12 months. However, prolonged days of bleeding resulted in fewer women continuing with the LNG-IUS at two years.
