A multicenter evaluation of endometrial ablation by Hydro ThermAblator and rollerball for treatment of menorrhagia

Abstract

Study objective: To compare results of endometrial ablation using the Hydro ThermAblator (HTA) and rollerball.

Design: Prospective, randomized study (Canadian Task Force classification I).

Setting: Nine private practice and university centers in the United States.

Patients: Two hundred seventy-six women with menorrhagia due to benign causes.

Intervention: Endometrial ablation with the HTA (187 women) or rollerball (89).

Measurements and main 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.

Conclusion: 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.
