A randomised controlled trial of day-care versus outpatient thermal balloon endometrial ablation using Thermachoice
ISRCTN ISRCTN73816767
ClinicalTrials.gov identifier
Public title A randomised controlled trial of day-care versus outpatient thermal balloon endometrial ablation using Thermachoice
Scientific title
Acronym N/A
Serial number at source N0436130477
Study hypothesis The safety and efficacy of thermal balloon endometrial ablation (EA) for the treatment of menorrhagia is well established. However the vast majority have been performed under general anaesthetic with its resultant risk and costs. Thermachoice has been performed in the outpatient setting both in this hospital and several others around the UK. The potential advantages of performing this technique in the outpatient setting are:
- The avoidance of general anaesthesia and its associated risks
- Earlier discharge from hospital
- Faster return to full mobility and fitness
- Less time of work
- Less cost to the patient

We plan to undertake a randomised controlled trial in order to compare out-patient (OP) and day-care (DC) Thermachoice. We will determine the acceptability, recovery and cost of both procedures. Longer term follow up will be undertaken with validated questionnaires comparing patients' menstrual symptoms before and after the treatment. We hypothesise that Thermachoice in the outpatient setting is a safe, acceptable treatment for menorrhagia.
