Hyperbaric Oxygen Therapy for Perianal Fistulizing Crohn's Disease Not Responsive or Intolerant to Conventional Care: HYPNOTIC Pilot Study
40 participantsStarted 2024-01
Plain-language summary
This study aims to test a new treatment called hyperbaric oxygen therapy (HBOT) for a severe type of inflammatory bowel disease called perianal Crohn's disease (PCD). PCD causes painful perianal infections and chronic drainage from fistula tracts, and current treatments are only moderately effective and may not be suitable for all patients. HBOT is a safe and commonly used treatment for chronic non-healing wounds and other conditions. Previous studies have suggested that HBOT may help heal fistulas in PCD patients, but these studies were small and lacked controls.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adults (\>17 years old)
* Diagnosis of Crohn's disease based on standard endoscopic, radiologic and/or histologic criteria.
* One or more perianal fistula tract connecting the rectum and the perianal skin. Patients must have active fistula drainage and/or a recurrent perianal abscess within the past month.
* Failure or intolerance of conventional therapy (imuran, methotrexate, anti-TNF therapies, vedolizumab and/or ustekinumab). Failure is defined as persistent perianal drainage or recurrent abscesses after a minimum of 3 months of therapy.
* Standard or care treatment has been stable (dose and treatment interval) for at least 3 months.
* Able to provide written consent to participate
Exclusion Criteria:
* Fistulas not believed to be due to Crohn's disease (examples include, obstetrical complications, tuberculosis, anorectal cancer or diverticular fistula).
* Rectovaginal fistulas.
* Undrained perianal abscesses on pelvic MRI exams (abscesses will require successful drainage by an exam under anaesthesia with or without seton prior to study inclusion).
* Surgical procedure such as an advancement flap, fistula plug, fistula glue or ligation of intersphincteric fistula tract (LIFT) procedure within the past 6 months.
* Diverting ostomies or ileal pouch anal anastomosis.
* Current or planned pregnancy or lactation during the study treatment period.
* Contraindications to HBOT (claustrophobia, incompatible implanted medical device, and other conditions) ba…
