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. The amount of menstruation was significantly decreased and dysmenorrhea was significantly relieved in 3, 6, and 12 months after surgery compared with before surgery. Only one patient underwent a laparoscopic hysterectomy due to dysmenorrhea which was not alleviated one month later. Serious IUD complications including expulsion and perforation were not observed. There was no development of new side effects than LNG-IUD insertion.

Conclusion: Our findings indicate that suture fixation of the LNG-IUD by hysteroscope is a safe, effective, and minimally invasive surgical procedure to prevent the device expulsion. It is a good solution for the treatment of large symptomatic adenomyosis and has shown to be effective in managing symptoms related to adenomyosis.
