Research summary
Endometriosis is a chronic, painful condition affecting up to 10% of women characterised by deposits of endometrial like cells outside the womb, most often in the pelvis. Symptoms are variable and it is not easily identified on scans. There is currently a long delay between the onset of symptoms and diagnosis, typically of around 8 years, leaving sufferers with pain an uncertainty. Much of this time is spent in primary care. Diagnosis is made by an invasive surgical procedure (laparoscopy) performed under general anaesthesia.
Endometriosis sufferers have a comparatively higher incidence of sub-fertility, which may in part be due to inappropriate inflammation in the lining of the womb (endometrium), pelvis and elsewhere. The relationship between the environment inside the womb and the environment in the pelvis is not well understood and the effect of surgically treating endometriosis is unknown.
This study aims to design a scoring system that can be used in primary care to select women at the highest risk of having endometriosis for referral to specialist services for diagnosis and treatment. The score will include symptoms (chronic pelvic pain, pain during periods, intercourse, and opening bowels), clinical history (BMI, family history of endometriosis, and previous pregnancies), and investigations such as pelvic ultrasound findings and CA-125 blood test. A weighting will be applied to each variable providing an overall score. We will apply the scoring system to a group of our patients to assess how well it identifies those with endometriosis.
In order to help determine the cause of endometriosis associated sub-fertility and identify possible targets for future treatment we will investigate how treating pelvic endometriosis impacts the environment in the womb. We will assess the lining of the womb before and after treatment to determine how this changes, which may help identify the root cause.
