title: A multicenter evaluation of endometrial ablation by Hydro ThermAblator and rollerball for treatment of menorrhagia.
abstract: OBJECTIVE
  To compare results of endometrial ablation using the Hydro ThermAblator (HTA) and rollerball.
  
  
  METHODS
  Prospective, randomized study (Canadian Task Force classification I).
  
  
  METHODS
  Nine private practice and university centers in the United States.
  
  
  METHODS
  Two hundred seventy-six women with menorrhagia due to benign causes.
  
  
  METHODS
  Endometrial ablation with the HTA (187 women) or rollerball (89).
  
  
  RESULTS
  Menstrual diaries were kept for 2 weeks and 3, 6, and 12 months after treatment. Reduction in diary scores to 75 or lower at 12 months was considered a success. For patients treated and followed according to protocol, success rates were 77% for HTA and 82% for rollerball. Amenorrhea rates at 12 months were 40% and 51%, respectively.
  
  
  CONCLUSIONS
  Endometrial ablation with the HTA is safe and effective. It offers an advantage over rollerball ablation of being an office-based procedure, which reduces anesthesia requirements and obviates problems of fluid absorption.
