Microwave endometrial ablation at a frequency of 2.45 GHz. A pilot study.

OBJECTIVE

To investigate the clinical application of a microwave tissue coagulator at 2.45 GHz with a needle electrode customized for endometrial ablation.

STUDY

DESIGN

In a pilot clinical study, endometrial ablation was performed under intravenous thiopental anesthesia on five women suffering from hypermenorrhea caused by aplastic anemia (3), von Willebrand's disease (1) and a submucosal myoma (1) using a microwave tissue coagulator at 2.45 GHz.

RESULTS

Four patients were amenorrheic after endometrial ablation. The patient with the submucosal myoma experienced minor menstrual bleeding. No notable complications were observed during or after ablation.

CONCLUSION

Endometrial ablation using a microwave tissue coagulator at 2.45 GHz is a simple and useful method of treating hypermenorrhea.
