Anal fistula surgery showdown: which technique spares continence?
NCT ID NCT07579715
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two common surgeries for perianal fistula—a painful tunnel near the anus. One hundred adults were split into two groups: one received the LIFT procedure (which aims to preserve muscle control) and the other received fistulotomy with a seton (a thread placed in the tunnel). Researchers measured healing time, recurrence, pain, and whether patients kept normal bowel control. The goal is to find which approach offers better recovery and fewer complications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- surgical procedure (LIFT or fistulotomy with seton)
- What this could lead to
- If this study shows clear advantages, it could help surgeons choose the best technique to reduce recurrence and preserve bowel control for patients with anal fistula.
- What could go wrong
- This is a small, completed comparative study, not a large randomized trial. Results may not apply to all fistula types or patients with other health conditions.
