Abstract
Objective: To investigate the feasibility and safety of magnetic resonance guided focused ultrasound surgery (MRgFUS) ablation treatment for uterine fibroids and adenomyosis. Methods: From February 2017 to July 2018, a total of 61 women in Foshan Hospital of Traditional Chinese Medicine with uterine fibroids or adenomyosis (36 cases of fibroids and 25 cases of adenomyosis) were included for treatment of MRgFUS, mean age was 27-48 (39±5) years. The treatment status, treatment effect and complications were recorded, and the differences between myoma and adenomyosis were compared. Results: Thirty-two (88.9%) patients of fibroid group and twenty-one (84.0%) patients of adenomyosis group were completed MRgFUS treatment respectively (P>0.05). The spot energy of adenomyosis group was 1 039-5 698(2 852±991) J, which was higher than 600-6 466(2 485±1 137) J of fibroid group (P<0.01). There was no significant statistical difference in mean temperature of spot and ablation time between the two groups (P>0.05).The non-perfusion volume ratio (NPVR) of the fibroid and adenomyosis group was 54%-99%(84%±15%) and 60%-98%(82%±12%) and there was no significant statistical difference (P>0.05), but the ablation efficiencies of adenomyosis group was less than fibroid group (0.8-4.3(2.1±0.9) cm(3)/min vs 1.3-7.8(3.6±1.5)cm(3)/min, P<0.01).The incidence of complications of adenomyosis group was 47.6%(10/21), it was higher than fibroid group 18.8%(6/32) (P<0.05). Conclusions: MRgFUS is a non-invasive, safe and effective treatment for both uterine fibroids and adenomyosis. Compared with uterine fibroids, MRgFUS treatment of adenomyosis has some disadvantages such as higher energy, lower ablation efficiency and more adverse reactions, and further optimization is needed.
