Suture Fixation of Levonorgestrel-Releasing Device Using the Hysteroscopic Surgery System

BACKGROUND: The levonorgestrel-releasing intrauterine system (LNG-IUS) is a widely recognized method for contraception and the management of various gynecological conditions. However, the placement of LNG-IUS can be particularly challenging in patients with large or anatomically irregular uteri. The objective of this study was to evaluate the efficacy and safety of hysteroscopic cold-knife-assisted suture fixation of the LNG-IUS in the uteri of patients diagnosed with adenomyosis. METHODS: We retrospectively analyzed the data of patients who underwent LNG-IUS placement with the assistance of cold-knife hysteroscopy. The evaluation criteria included surgical success rates, postoperative complications, and subsequent follow-up of LNG-IUS. RESULTS: Our findings indicated that LNG-IUS placement was successfully achieved with cold-knife hysteroscopy, even in cases characterized by large uterine volume or abnormal uterine morphology. The procedure demonstrated a low incidence of postoperative complications, with no instances of device expulsion or displacement. Additionally, it resulted in a reduction of vaginal bleeding and alleviation of dysmenorrhea. CONCLUSION: Hysteroscopic cold-knife-assisted suture fixation of LNG-IUS offers an effective solution for patients with a history of device expulsion, significantly reducing the expulsion rate and demonstrating high safety and efficacy.
