Radiofrequency ablation for anal fistula
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 20 and 74 years old.
- You have an anal fistula (an abnormal tunnel between the back passage and the skin) that is high or complex, or one that has a seton (a temporary thread left in to help drain it).
- You have a fistula linked to Crohn's disease, or one that is complex, including if you've had previous pelvic or gynecologic surgery or the fistula keeps coming back.
- You do not have a simple fistula that can be cured with a minor cut (fistulotomy) without much risk to your sphincter muscles.
- Your fistula is not related to cancer, you are not pregnant, you do not have a stoma (a bag for bowel waste), and you have no metal clips in your back passage from past surgery.
- You understand the study and are willing to sign a consent form.

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 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.
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 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 trial tests whether a special tissue therapy can help heal complex anal fistulas that involve a large part of the sphincter muscle. It is for adults who need surgery for this condition and do not have certain other health issues.
This study tests a less invasive surgical method (a mucosal advancement flap) for treating complex anal fistulas. It aims to see if this approach works well for people who have a single fistula tunnel and haven't had this type of operation before.
