Abstract
Study Objective: To compare efficacy of rollerball endometrial ablation with low-voltage (Cut) versus high-voltage (coag) waveforms.
Design: Pilot comparative clinical study (Canadian Task Force Classification II-1).
Setting: University-affiliated teaching hospital.
Patients: Fifty premenopausal women with menorrhagia.
Intervention: Women with menorrhagia were allocated randomly to thermal destruction of the endometrium by a 5-mm rollerball With unmodulated cutting Current or modulated coagulating current. Complication rate, clinical Outcomes, and need for reintervention were evaluated.
Measurements and Main Results: At 2 years of follow-up, the reintervention rate was 26.3% in file cutting waveform group versus 31.4% in the coagulating waveform group. This difference was not statistically significant. Hysterectomy was performed in 3 (14%) women ill the cutting waveform group and 5 (20%) women in the coagulating waveform group. There were no complications in either group.
Conclusion: Both cutting and coagulating waveforms are equally effective for hysteroscopic endometrial ablation with the rollerball. Journal of Minimally Invasive Gynecology (2009) 16, 350-3 (c) 2009 AAGL. All rights reserved.
