Considerations for performing microwave endometrial ablation (MEA) - Three cases with abnormal test results of endometrial tissue discovered by chance when performing MEA.

Introduction

Microwave endometrial ablation (MEA) is beginning to be used widely in Japan as a minimally invasive alternative to conventional total hysterectomy for functional hypermenorrhea, uterine fibroids, hypermenorrhea due to organic diseases such as uterine adenomyosis, and acute heavy uterine bleeding. Method: MEA was introduced in our hospital in January 2016. It is performed after a screening via cytodiagnosis and histodiagnosis to ensure that there are no malignant diseases in the uterus. Histopathological examination by endometrial curettage during MEA revealed three cases of endometrial abnormalities. In all cases, radical surgery was performed, the postoperative course was good, and no recurrence was observed. Here, we report three cases in which abnormal endometrial tissue findings were observed in histopathologic examinations via total endometrial curettage during MEA.

Conclusion

When performing MEA, it is important to perform detailed examinations and careful monitoring of post-operative progress bearing in mind potential malignant uterine diseases.
