Outcome Measures
Primary Outcomes (1)
Amenorrhoea
The objective of any treatment for HMB is to substantially reduce the amount of menstrual blood loss.Amenorrhoea rates are often chosen as the primary outcome measure in clinical trial of the effectiveness of endometrial ablation in women with HMB.
6 months after the intervention.
Secondary Outcomes (1)
Visual analogue scale for assessment of pain
24 hours
Study Arms (2)
novasure
ACTIVE COMPARATORBipolar radio-frequency energy ablation of the endometrium by thermal therapy under impedance control. The bipolar current generated by the device produces a tapered depth of ablation with shallower ablation in the cornual regions / lower uterine segment and a deeper ablation in the mid-body of the uterus..
thermachoice
OTHERThermachoiceTM III thermal balloon ablation
Interventions
Bipolar radio-frequency energy ablation of the endometrium by thermal therapy under impedance control. The bipolar current generated by the device produces a tapered depth of ablation with shallower ablation in the cornual regions / lower uterine segment and a deeper ablation in the mid-body of the uterus..
ThermachoiceTM III thermal balloon ablation
Eligibility Criteria
You may qualify if:
- Women with no desire to preserve their fertility who have heavy menstrual bleeding without organic pathology (DUB) of more than six months duration
- Premenopausal follicular follicle stimulating hormone (FSH) level of less than 40 IU/L.
- Associated functional disability (negative impact on life quality).
- Lack of response to medical treatment.
- Prepared to undergo surgical treatment without general anaesthesia
You may not qualify if:
- Women under 25 years
- Suspected genital tract infection
- Uterine pathology including endometrial pathology on endometrial biopsy (e.g. endometrial hyperplasia or carcinoma) and structural lesions (e.g. uterine malformations, adhesions, polyps, submucous fibroids or extracavity fibroids \> 3cm in diameter) as identified on pelvic ultrasound and/or outpatient hysteroscopy.
- Uterine cavity length \>11cm
- Adnexal pathology
- Previous open myomectomy or endometrial ablation / resection and classical caesarian section
- patients considered vulnerable (e.g. current mental illness, emotionally labile, learning difficulties, immaturity)
