Summary

This study compares three surgical techniques for treating a common type of anal fistula (a tunnel between the anal canal and skin). The trial will enroll 90 adults aged 18-65 who have not had fistula surgery before. Researchers will measure healing, recurrence, and impact on bowel control over 12 months to determine which approach works best.

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 (fistulotomy, LIFT with laser, or open LIFT with laser)
What this could lead to
If successful, this study could identify the most effective surgical technique for treating trans-sphincteric perianal fistula, leading to higher healing rates and fewer recurrences.
What could go wrong
This is a small, early-stage trial with only 90 participants, so results may not apply to everyone. Surgery carries risks like infection, bleeding, or changes in bowel control.
