Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Women of reproductive age (<50 years) and who have a regular cycle that suggests ovulation, who are due to undergo hysterectomy for benign gynaecologcical conditions, will be recruited into the study. Following ethical approval and in the context of fully informed and written consent, 45 women will be randomised to one of three groups (n = 15 per group) in one single block of n=45 in a parallel-group design.

In the follicular phase of the cycle prior to hysterectomy Group 1 will receive a Lipiodol hysterosalpingogram (HSG), Group 2 will receive a control water soluble contrast media HSG and Group 3 will receive no intervention.

The dose of administered Lipiodol will not exceed 10mL in each case for each patient, with the duration of administration being confined to time of HSG procedure only (once off use). The mode of administration is via instillation through the cervical canal into the cervix and follopian tubes via a hysterosalpingography (HSG) procedure.

The attending Radiologist/physician will determine the exact dose of administered Lipiodol at the time of a HSG procedure. The minimum dose of Lipiodol to be administered above 5mL (including dead-volume in catheter) and until Lipiodol spill through the fimbriae is visualised by attending specialist radiologist under flouroscopy. A participant’s HSG procedure can vary in length, depending on clinical conditions between patients, however is not expected to exceed 20 mins in duration. A specialist Radiologist will administer the HSG procedure. The mode of administration is via instillation through the cervical canal using either a) Leech Wilkinson Cannula, or b) Cook Ballloon HSG Catheter, or c) a Rocket HSG Catheter. The type of water soluble contrast media utilised will be either Telebrix Hystero or agitated saline (which ever method is preferred by the Radiologist and in accordance to local protocol for HSG). The water soluble contrast media will be administered as per the lipidol administration procedure, the minimum dose will be above 5mL.

All HSG procedures completed by the respective Radiologists in each center will follow a clearly stipulated protocol for HSG as described above. Any deviations will be recorded by the attending radiologist and reported immediately to the trial coordinator.

Timepoint [1] 322485 0
There are two blood venepunctures (20ml of blood collected on each occasion) at two time points: 1) prior to intervention on the day of pipelle sampling and 2) at the time of hysterectomy.
Primary outcome [2] 322588 0

Timepoint [2] 322588 0
Assessment will take place prior to intervention on the day of pipelle sampling, at the timeat two time points: 1) prior to intervention on the day of pipelle sampling and 2) at the time of hysterectomy.

Can healthy volunteers participate?
Yes
Key exclusion criteria
Exclusion criteria are:
- Any fibroid larger than 10cm in maximum dimension; (this change was made after 2 participants were recruited and at the initial screening stages of the MoFEEL trial)
- Known Malignancy;
- Known carrier of organism(s) associated with sexually transmitted infection (STI);
- Women scheduled for purely vaginal hysterectomy.
Women will complete our modification of the standardised World Endometriosis Research Foundation Endometriosis Phenome Harmonisation Project (EPHect) patient questionnaire, which is appropriate for any woman with benign gynaecological disease entering a research trial.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
45 women will be randomised to one of three groups (n = 15 per group) in one single block of n=45 in a parallel-group design.

Allocation concealment will involve contacting the holder of the allocation schedule who was "off-site" or at central administration site (the trial coordinator).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence generation will involve simple randomisation using a randomisation table from a statistic book.
Stratified allocation will be employed in this study, utilising factors that can be used for stratification include centre, age, gender or previous treatment.
Masking / blinding

Statistical methods / analysis
Fifteen per group is a typical number of participants in trials that might unearth important differences or non-significant trends in the key immune-biological variables under study. Certainly, this number of participants per group will be sufficient to give information about likely differences in magnitude between the different interventions and the variation of the chances for each variable within each group.
