What this trial studies

This trial investigates the use of Hyperbaric Oxygen Therapy (HBOT) to alleviate pelvic pain associated with endometriosis, a condition affecting approximately 10% of women. The study aims to provide an alternative treatment option for patients who have been suffering from refractory pain for over six months and are on a waitlist for surgical intervention. By utilizing a monoplace hyperbaric chamber, the therapy seeks to reduce inflammation and promote healing in affected tissues. The trial will assess the effectiveness of HBOT in improving pain levels and overall quality of life for participants.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with refractory pelvic pain due to endometriosis for more than six months.

Not a fit: Patients with chronic pain from conditions unrelated to endometriosis or those medically unfit for hyperbaric treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide significant pain relief and improve the quality of life for women suffering from endometriosis-related pain.

How similar studies have performed: While the use of HBOT for endometriosis is a novel approach, preliminary research suggests potential benefits in reducing inflammation, though further studies are needed to confirm efficacy.
