Researchers are exploring the feasibility and therapeutic outcomes of hysteroscopic suture fixation for levonorgestrel-releasing intrauterine systems in patients with adenomyosis. The method involves a novel suture fixation technique, with some studies also investigating the use of high-intensity focused ultrasound in combination with the intrauterine system. The effectiveness and potential risks of this approach, including unpredictable bleeding, are being examined in relation to different subtypes of adenomyosis.
