What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
