Objective: To compare the effectiveness of bipolar radiofrequency (Novasure (R)) ablation and balloon endometrial ablation (Thermablate (R)). Study design: We performed a multi-center double blind, randomized controlled trial in three hospitals in The Netherlands. Women with heavy menstrual bleeding were randomly allocated to bipolar or balloon endometrial ablation, performed in the office, using a paracervical block. The primary outcome was amenorrhea. Secondary outcome measures were pain, satisfaction, quality of life and reintervention. Results: 104 women were randomized into the bipolar (52) and balloon (52) groups. After 12 months amenorrhea rates were 56% (29/52) in the bipolar group and 23% (12/52) in the balloon group (relative risk (RR) 0.6, 95% confidence interval (CI) 0.4-0.8). The mean visual analog pain score of the total procedure was 7.1 in the bipolar group and 7.4 in the balloon group (P
