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

OBJECTIVE: To investigate the clinical application of a microwave tissue co agulator at 2.45 GHz with a needle electrode customized for endometrial abl ation. STUDY DESIGN: In a pilot clinical study, endometrial ablation was performed under intravenous thiopental anesthesia on five women suffering from hyper menorrhea 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 pat ient with the submucosal myoma experienced minor menstrual bleeding. No not able complications were observed during or after ablation. CONCLUSION: Endometrial ablation using a microwave tissue coagulator at 2.4 5 GHz is it simple and useful method of treating hypermenorrhea.
