About the study: BC Women’s Centre for Pelvic Pain and Endometriosis is a tertiary referral centre in British Columbia dedicated to managing chronic pelvic pain (CPP) and endometriosis. The Centre offers a unique interdisciplinary approach that includes pain education workshops, pelvic floor physiotherapy, counselling, and medical and surgical management. The purpose of this study is to prospectively collect data from patients at the clinic to investigate long-term patient outcomes, and the etiology and treatment of CPP. Participants in the study will have their clinical intake questionnaires, physical exam, surgery, and pathology data included in the research and answer follow-up questionnaires at 6 months and 1-5 years.

Why is this research important? Chronic pelvic pain (CPP) (pelvic pain that lasts at least 3-6 months in duration) affects 15% of reproductive-aged women. It is a condition that can involve many physical, psychological, and behavioural consequences and have a devastating impact on quality-of-life. One of the most common origins of CPP is endometriosis, a condition in which endometrial tissue that usually lines the uterus grows outside of the uterus. However, pelvic pain may also result from numerous other gynaecological, musculoskeletal, gastrointestinal, or urological conditions, and can be difficult to manage. Therefore, there is benefit to an interdisciplinary approach in the management of CPP compared to standard treatment.

Study status: Recruitment, data collection, data analysis, and manuscript development is ongoing.

Who can participate: All patients referred for chronic pelvic pain and/ or endometriosis to the BC Women’s Centre for Pelvic Pain and Endometriosis.
