DIAMOND is a research study to compare surgery with hormone treatment for women with deep endometriosis.
Endometriosis is a common condition affecting 1 in 10 women, which can cause severe pain. It happens when cells similar to those lining the womb grow outside it, generally on surfaces and organs within the pelvic cavity, causing bleeding, scarring and inflammation. Occasionally, rather than growing on or very near the surface, the endometriosis cells can grow deeper into tissues and organs, such as the bowel, bladder and the vagina causing a painful condition which used to be known as “deep infiltrating endometriosis” and is now called deep endometriosis (DE).
We are recruiting women in the UK aged 18-49 seeking treatment for pain with confirmed deep endometriosis and suitable for either surgical or medical management and able and willing to give informed consent to participate.
If you are eligible, would like to take part and your local hospital is a study site, they will send you information about the DIAMOND study.
To take part you will be asked to sign a consent form and asked some questions about your health and your endometriosis symptoms. After this you will be randomised to receive either:
• Surgery (with or without neoadjuvants or analgesics)
• Hormone treatment (with or without neuromodulator or analgesics)
Whichever group you are in, you will continue to receive NHS care.
We will follow you up in the study for 18 months using by sending questionnaires for you to complete at home.
There is an extra part of the study that is optional. In this extra part, we will ask some participants to take part in an interview. If you agree to take part in the DIAMOND study, we will ask you whether or not you would like to receive information about these interviews and to be contacted by the interview team.
