Efficacy and satisfaction rate comparing endometrial ablation by rollerball electrocoagulation to uterine balloon thermal ablation in a randomised controlled trial.

OBJECTIVE: To compare two methods of endometrial ablation, hysteroscopic rollerball electrocoagulation (RBE) and non-hysteroscopic uterine balloon thermal ablation (Thermachoice trade mark ), regarding efficacy for reducing dysfunctional uterine bleeding and patients satisfaction rate. METHODS: A randomised controlled study was performed in a teaching hospital at the department of gynaecology. One hundred and thirty-seven premenopausal women with dysfunctional uterine bleeding proved by validated menstrual score list were included. Endometrial ablation by a hysteroscopic or non-hysteroscopic method was performed by one gynaecologist. RESULTS: Reduction of menstrual blood loss was significantly more successful at 24 months for thermal ablation with uterine balloon. Success rate measured by menstrual score < 185 for rollerball and thermal balloon ablation are equivalent at 12 and 24 months post-operatively. Satisfaction of the patients for both methods at 24 months post-operatively is not significantly different (respective 75% for rollerball and 80% for uterine balloon). CONCLUSIONS: Endometrial ablation by uterine balloon thermal ablation (Thermachoice trade mark ) is equally effective as hysteroscopic RBE of the endometrium.

Endometrial ablation by rollerball electrocoagulation compared to uterine balloon thermal ablation. Technical and safety aspects.

OBJECTIVE: To compare two methods of endometrial ablation, hysteroscopic rollerball electrocoagulation (RBE) and non-hysteroscopic uterine balloon thermal (UBT) ablation (Thermachoice), regarding intra- and post-operative technical complications and safety aspects. STUDY DESIGN: A randomised controlled study in a teaching hospital, 139 pre-menopausal women with dysfunctional uterine bleeding proved by a validated menstrual score list were enclosed. Endometrial ablation by a hysteroscopic or non-hysteroscopic method was performed. RESULTS: Rollerball electrocoagulation carries a significantly higher risk of intra-operative complications compared to uterine balloon thermal ablation and is a significantly more time consuming procedure. Post-operative complication rates in both groups were low, but post-operative analgesics were prescribed significantly more in the uterine balloon group. CONCLUSION: Endometrial ablation by uterine balloon thermal ablation (Thermachoice) is a safe and simple non-hysteroscopic procedure.
