Brain scans may predict surgery success for endometriosis pain
NCT ID NCT07313345
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study from the University of Oxford is looking at whether brain scans can predict which women with severe endometriosis will have less pain after surgery. Researchers will scan the brains of 100 women before their operation and then check their pain levels a year later. The goal is to find a way to avoid surgery in women who are unlikely to benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors identify which patients are most likely to benefit from surgery for severe endometriosis, avoiding unnecessary procedures.
- What could go wrong
- This is a small observational study, not a treatment trial. It may not find a reliable way to predict pain outcomes, and results may not apply to all patients.
