abstract

  • STUDY OBJECTIVE: To compare the safety and effectiveness of the NovaSure impedance-controlled endometrial ablation system with hysteroscopic wire loop resection plus rollerball ablation for treatment of excessive uterine bleeding in premenopausal women. DESIGN: Randomized, multicenter, double-arm study (Canadian Task Force classification I). SETTING: Nine academic medical centers and private offices. PATIENTS: Two hundred sixty-five premenopausal women with symptomatic menorrhagia. INTERVENTION: Ablation performed with the NovaSure system or wire loop resection and rollerball. MEASUREMENTS AND MAIN RESULTS: Success [pictorial blood loss-assessment chart (PBLAC) score < or =75] was achieved in 88.3% of NovaSure-treated and 81.7% of rollerball-treated patients. One year after treatment 90.9% and 87.8%, respectively, reported normal bleeding or less (PBLAC < or =100) and 41% and 35%, respectively, experienced amenorrhea (PBLAC = 0). Mean procedure time was 4.2 minutes (average 84 sec) in the NovaSure group and 24.2 minutes in the rollerball group. Local and/or intravenous sedation was administered in 73% of NovaSure patients and 18% of rollerball patients. Intraoperative adverse events occurred less frequently with NovaSure (0.6%) than with rollerball (6.7%). Postoperative adverse events occurred in 13% and 25.3% of patients, respectively. CONCLUSION: The NovaSure system was safe and effective in treatment of women with menorrhagia. The procedure is both quick and effective, and eliminates the expense and side effects of endometrial pretreatment.
