Laser treatment vs standard surgery for uncomplicated anal fistula
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 55 years old.
- You are scheduled for surgery to treat an uncomplicated perianal fistula (a simple tunnel near the anus).
- You have only one fistula tract (one tunnel).
- The fistula involves less than 30% of the external anal sphincter (the muscle that controls stool release), and the tunnel only goes through the skin layer (subcutaneous tissue).
- You do not have a recurrent or complex fistula, a history of bowel cancer, inflammatory bowel disease (like Crohn's or ulcerative colitis), or any condition that makes anesthesia unsafe.

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 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 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 looks at whether cleaning the bowels before a type of fistula surgery called FiLaC helps the healing process. It compares patients who have bowel prep with those who don't, to see if it improves recovery.
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 study looks at whether the timing of surgery for an anal fistula affects healing and whether it comes back. If you are planning surgery for a first-time fistula, you may be able to join and help doctors learn the best time to operate.
