Two surgeries for high anal fistula: which works better?
Part of Digestive system clinical trials.
This study compares two surgical techniques—TROPIS and coring-out fistulectomy—for treating high anal fistulas (a tunnel connecting the anal canal to the skin that goes through a lot of muscle). It aims to find which method helps heal better and is safer for you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a high anal fistula (involving more than 1/3 of the sphincter muscle), either new or returning.
- Your fistula is not caused by cancer, inflammatory bowel disease (like Crohn's or ulcerative colitis), injury, or radiation treatment.
- You do not have a low anal fistula (milder form that stays near the anal opening).
- You do not have trouble controlling bowel movements (fecal incontinence) before surgery.
- You have not had an injury to the levator ani muscle (a key pelvic muscle) before.

This trial compares two surgical methods (IFOC and LIFT) for treating high anal fistulas—abnormal tunnels that form near the anus. The goal is to determine which approach works better and has fewer side effects.
This study compares two surgical techniques (fistula rerouting and LIFT) for treating a high perianal fistula, a tunnel that forms in the muscle around the anus. It aims to find which method works better for people with this condition.
This trial compares two surgical techniques to treat a complex type of anal fistula (an abnormal tunnel between the anal canal and skin). It aims to find which approach offers better healing and fewer risks.
This trial compares two laparoscopic (keyhole) surgery methods to fix a uterovesical fistula, which is an abnormal opening between the bladder and uterus that can happen after C-section or other pelvic surgery. The goal is to see which method works best.
This trial compares three surgical methods to treat a type of anal fistula (an infected tunnel between the bowel and skin near the anus). The goal is to find which technique works best and has the fastest recovery.
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.
