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.
