Study summary

The purpose of this data registry is to prospectively collect data from patients referred to an interdisciplinary clinic for pelvic pain and endometriosis to investigate long-term patient outcomes, prognosis, predictors, causes, and treatment of pelvic pain and endometriosis.

Read the detailed description

The BC Women's Centre for Pelvic Pain and Endometriosis is the tertiary referral centre for endometriosis/pelvic pain in British Columbia, Canada. The Centre offers a unique interdisciplinary approach including minimally invasive surgery, hormonal and other medical therapy, pain education, physiotherapy, and CBT/mindfulness.

After informed consent, patients prospectively consent to data collection in the online registry. The registry consists of patient intake questionnaires (including validated measures), physical and ultrasound examination, review of medical records, surgical findings, and annual outcomes to 5 years.

The online data registry is housed in the Research Electronic Data Capture (REDCap) platform located at BC Children's Hospital.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2016 (actual). Primary completion is estimated for Dec 2028, 150 months after the start.

Of 155 non-industry observational studies under Endometriosis, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 48. This study's planned 150 months is above that.

Counting every sponsor, half of 182 studies reached it within 30 months; a quarter within 14 and three quarters within 47.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
