The suture fixation of the levonorgestrel-releasing intrauterine device with hysteroscope for the treatment of adenomyosis in patients at high risk of device expulsion-a prospective observational study.

Background: This study aimed to investigate the safety and efficacy of suture fixation of the levonorgestrel-releasing intrauterine device (LNG-IUD) by hysteroscope for the treatment of adenomyosis in patients at high risk of device expulsion, to provide a viable treatment option for these patients.

Methods: Twenty-one patients with large symptomatic adenomyosis were sewed and fixed with the LNG-IUD in the uterus by hysteroscopy to prevent the device expulsion.

Results: In this prospective case series, all 21 patients were successfully sewed and fixed with the LNG-IUD in the uterus by hysteroscopy.
