Combination of microwave endometrial ablation and postoperative dienogest administration is effective for treating symptomatic adenomyosis.

AIM

Menorrhagia and dysmenorrhea are common symptoms. Uterine adenomyosis is one of the causes of menorrhagia and dysmenorrhea. These symptoms often decrease the quality of life in women. Microwave endometrial ablation (MEA) is a recently developed procedure that enables endometrial ablation. Dienogest has long been used to suppress endometrium development and reduce adenomyosis-related dysmenorrhea. However, some cases could be resistant to dienogest. In this study, we evaluated the efficacy of a combination of MEA and postoperative dienogest in reducing adenomyosis-related dysmenorrhea and menorrhagia.

METHODS

Ten patients with hormone treatment-resistant symptomatic adenomyosis underwent MEA and were administered oral dienogest after the procedure. The primary endpoints were reduction in pain recurrence and anemia. The secondary endpoint was a change in the adenomyosis lesion and its symptomatic recurrence.

RESULTS

Statistically significant improvements were seen in the visual analog scale score and hemoglobin levels in women post-treatment. The difference in myometrial thickness pre- and post-MEA was statistically significant. There were no cases of symptomatic recurrence.

CONCLUSION

The combination of MEA and postoperative dienogest is useful for treating uterine adenomyosis with menorrhagia and dysmenorrhea.
