Thermal balloon and rollerball ablation to treat menorrhagia: a multicenter comparison.

OBJECTIVE: To compare the clinical efficacy and safety of a thermal uterine balloon system with hysteroscopic rollerball ablation in the treatment of dysfunctional uterine bleeding.

METHODS: Two hundred fifty-five premenopausal women were treated in a randomized multicenter study comparing thermal uterine balloon therapy with hysteroscopic rollerball ablation for the treatment of menorrhagia. Preprocedural and postprocedural menstrual diary scores and quality-of-life questionnaires were obtained. Twelve-month follow-up data are presented on 239 women.

RESULTS: Twelve-month results indicated that both techniques significantly reduced menstrual blood flow with no clinically significant difference between the two groups as reflected by return to normal bleeding or less (balloon 80.2% and rollerball ablation 84.3%). Multiple quality-of-life questionnaire results were also similar, including percent of patients highly satisfied with their results (balloon 85.6% compared with rollerball 86.7%). A 90% decrease in diary scores was seen in more than 60% of patients in both groups. Procedural time was reduced significantly in the uterine balloon therapy group. Intraoperative complications occurred in 3.2% of the hysteroscopic rollerball patients, whereas no intraoperative complications occurred in the thermal balloon group.

CONCLUSION: In the treatment of dysfunctional uterine bleeding, uterine balloon therapy is as efficacious as hysteroscopic rollerball ablation and may be safer.
