Laser and blood-based treatment for recurrent anal fistula
Part of Digestive system clinical trials.
This trial tests a new treatment for a type of anal fistula that keeps coming back after surgery. It uses special procedures to clean the fistula tract and then inject a concentrate of your own blood (called PRGF) to help it heal. The goal is to close the fistula without cutting the muscle.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You've had at least 2 surgeries for this anal fistula that didn't heal it.
- The fistula is the type that goes between certain layers of the anal muscles (intersphincteric or transsphincteric).
- You have a seton (a soft thread) in place for at least 6 months.
- No active infection (pus, swelling, or redness) in the anal area right now.
- The fistula has only one tunnel (no branches) as seen on an ultrasound.
- You are 18 or older, have a normal platelet count, and are not pregnant.

This study compares two ways to treat a simple anal fistula: traditional surgery (fistulectomy) versus a newer technique that uses a laser to close the fistula tract. The goal is to see which method heals better and causes less discomfort.
This study compares two ways to treat a simple anal fistula—an abnormal tunnel that forms between the inside of the anus and the nearby skin. One method uses a laser to close the tunnel, while the other uses standard surgery to cut it open. If you have a single, simple fistula, this trial may help you understand which treatment works better.
This study compares three different surgical methods for treating a type of anal fistula that passes through the sphincter muscle. It aims to find which technique is most effective and safe, which could help patients recover with less pain or risk.
This study follows people having surgery for an anal fistula to see how well they recover. It uses your feedback to measure results, and you'll have check-ins for a year.
This trial tests a new procedure called Fistura to treat complex anal fistulas (abnormal tunnels between the anal canal and skin). It uses radiofrequency energy to close the fistula while preserving muscle. The study is for people whose fistula has already been drained with a temporary seton stitch.
This study tests a treatment called radiofrequency ablation (RFA) that uses heat to destroy the fistula tract (the abnormal tunnel) while trying to protect the muscles that control bowel movements. It may help people with complex or high-risk anal fistulas avoid surgery that could harm these muscles.
