Laser zaps leakage: new device tested for bowel control
NCT ID NCT07436676
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests a laser device (ALVIV) for people with fecal incontinence. Twelve participants will receive 4-6 treatments, three weeks apart, and keep diaries of leakage episodes. The main goal is to check safety and see if the device works without problems.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ALVIV laser device
- What this could lead to
- If it works, this could offer a non-surgical option to reduce accidental bowel leakage and improve quality of life.
- What could go wrong
- This is a very early, small study (12 people) focused on safety, not proof of effectiveness. The device may not work or could cause side effects.
