Comparing two surgeries for high anal fistula
Part of Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 16 years or older.
- You have a confirmed high transsphincteric perianal fistula (a deep tunnel involving the muscle that controls the anus), diagnosed by MRI.
- You are healthy enough for surgery (classified as ASA I-III).
- You have not had any prior major surgery for this fistula, apart from simple drainage.
- You do not have Crohn's disease, tuberculosis, cancer-related fistula, or a horseshoe fistula (a complex tunnel shape).
- You are not pregnant, are not immunocompromised, and do not have uncontrolled diabetes (HbA1c > 8%).
- You do not have an active, undrained abscess at the time of surgery.

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.
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 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 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.
