Heat therapy may seal troubling anal fistulas without surgery

NCT ID NCT07452666

Summary

This pilot study tests whether a device that delivers controlled heat (radiofrequency ablation) can safely close perianal fistulas—abnormal tunnels between the anal canal and skin. Eighty adults with certain types of fistulas will receive a single RFA treatment. Researchers will check if the fistula closes by 6 months, track any return of the fistula, and monitor for side effects like pain or infection.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Radiofrequency ablation (RFA) device
What this could lead to
If successful, this could offer a new, less invasive treatment option for perianal fistulas that avoids cutting sphincter muscles.
What could go wrong
This is a small, early pilot study with no control group. The procedure may not work for everyone, and risks include pain, bleeding, infection, or changes in bowel control.
