[The second generation endometrial ablation (NovaSure) improves efficacy of levonorgestrel-releasing intrauterine system in management of adenomyosis].

OBJECTIVE

To determine the efficacy of second generation endometrial ablation (NovaSure) combined with levonorgestrel-releasing intrauterine system (Mirena) in the treatment of adenomyosis.

METHODS

Clinical data of patients with adenomyosis admitted in Women's Hospital, Zhejiang University School of Medicine from January 2015 to December 2018 were retrospectively analyzed. Among 66 patients, 44 received Mirena placement only (control group) and 22 received Mirena placement and NovaSure treatment (study group). The menstruation blood loss, dysmenorrhea score, uterine size, expulsion rate of Mirena and the patients' satisfaction rate were assessed in two groups.

RESULTS

There was a significant reduction in menstruation blood loss (<0.05) and significant improvement in dysmenorrhea (<0.05) after the treatment in both groups. The patients in study group had more marked improvement in menstruation blood loss than those in control group (<0.05). The patients' satisfaction was higher and the expulsion rate of Mirena was lower in study group than that in control group (all <0.05). The score of dysmenorrhea and the size of uterine had no significant difference between two groups (all >0.05).

CONCLUSIONS

NovaSure can improve the efficacy of Mirena in treatment of adenomyosis.
