Clinical evaluation of HIFU combined with GnRH-a and LNG-IUS for adenomyosis patients who failed to respond to drug therapies: two-year follow-up results

Abstract

Objective To investigate the clinical effect of high intensity focused ultrasound (HIFU) ablation combined with gonadotropin-releasing hormone agonist (GnRH-a) and levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of adenomyosis patients who failed to respond to drug therapies. Study design A total of 47 patients with adenomyosis who had failed to respond to drug therapies and had no fertility desires were treated with HIFU combined with GnRH-a and LNG-IUS. The score of dysmenorrhea and menstrual volume were measured at pre and 6-, 12-, 18-, 24-month post-HIFU. Results All patients completed HIFU ablation without major postoperative complications. Compared with the symptom scores before the HIFU treatment, the score of dysmenorrhea and menstrual volume decreased significantly at 6, 12, 18 and 24 months after HIFU treatment (p 0.05). The clinical success rate was 100%, 100%, 95.7% and 93.6% respectively at 6, 12, 18 and 24 months after the combined treatment. Conclusion The combined therapeutic regimen of HIFU, GnRH-a and LNS-IUS is safe and effective, which can be an alternative treatment option for patients with adenomyosis who failed to respond to drug therapies to avoid adenomyomectomy or hysterectomy.
