Simple and Novel Technique of Fixation for Levonorgestrel-Releasing Intrauterine Device for the Treatment of Uterine Adenomyosis

Levonorgestrel-releasing intrauterine device is widely used in the treatment of adenomyosis and heavy menstrual bleeding. For patients with large uterine cavity or abnormal uterine cavity, they might encounter the problem of downward displacement and expulsion of the device during treatment. Herein, this study reported an easy minimally invasive method using GyneFix intrauterine device system to fix levonorgestrel-releasing intrauterine device into the uterine fundal muscle layer. The two ends of the intrauterine devices were firstly bundled together tightly. The suction sheath was inserted into the uterine cavity until reaching the fundus. Then, the bundled intrauterine devices were inserted into the sheath and fixed the GyneFix knot at the uterine fundus following the GyneFix IUD installation method. In this way, the LNG-IUD could be fixed well in the uterine cavity. This outpatient procedure does not require any special preparation or training.
