Clinical Question: Is radio-frequency endometrial ablation more effective than balloon ablation for the treatment of menorrhagia?

Setting: Inpatient (any location) with outpatient follow-up

consideration Design: Randomized controlled trial (double-blinded)

Allocation: Concealed

Synopsis: In this trial, women with menorrhagia and no intracavitary abnormalities were assigned randomly (1:2) to the newer bipolar radio-frequency endometrial ablation technique (n = 83) or hot-water balloon ablation therapy (n = 43) The same surgeon treated all of the women The women and physician investigators who assessed results were blinded to treatment dispose assignment.

Women in the radio-frequency arrange were more likely to have amenorrhea at three six, nine, and 12 month after the step At 12 months, amenorrhea occurr in 43 percent of the women in the radio-frequency cluster and 8 percent of those in the balloon-therapy arrange (P < .001; number emergencyed to treat [NNT] = three; 95 percent confidence interval, couple to five). Patient satisfaction at 12-month follow-up was 90 percent in the radio-frequency arrange and 79 percent with balloon therapy (P = 003; NNT = 11) The mean duration of the surgical intervention was nine minutes in the radio-frequency collection and 14 minutes in the balloon-therapy group

The meditation was too small to determine whether the lower rate of dysmenorrhea in the radio-frequency dispose was statistically significant, although it would be clinically significant if place to be true (8 percent versus 16 percent) The application of mind also was too small and too short to descry a difference in hysterectomy rates.

Bottom Line: Amenorrhea is achieved more ofttimes with radio-frequency endometrial ablation than with hot-water balloon ablation. Women serve to be more satisfied with the radio-frequency technique undivided year after therapy. A reassessment of the treated women after a longer follow-up period is distressed (Level of Evidence: 1b-)
