title: Microwave endometrial ablation at a frequency of 2.45 GHz. A pilot study.
abstract: OBJECTIVE
  To investigate the clinical application of a microwave tissue coagulator at 2.45 GHz with a needle electrode customized for endometrial ablation.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  Endometrial ablation using a microwave tissue coagulator at 2.45 GHz is a simple and useful method of treating hypermenorrhea.
