Could your own blood heal a painful fistula? new trial investigates
NCT ID NCT04187651
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a gel made from a patient's own blood (platelet-rich plasma) can help close perianal fistulas—abnormal tunnels that form near the anus. One hundred adults with this condition will receive the gel during a procedure, and doctors will check if the fistula has healed using exams and MRI scans. The goal is to see if this natural approach works better than standard surgical methods.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- platelet-rich plasma (PRP) gel made from the patient's own blood
- What this could lead to
- If it works, this could offer a less invasive, natural treatment option for perianal fistula that may improve healing and reduce recurrence.
- What could go wrong
- This is an early-stage study without a control group, so results may not prove effectiveness. PRP is generally safe, but the fistula may still return or not heal completely.
