New anal insert aims to stop leakage and improve lives
NCT ID NCT04657588
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new, liquid-filled anal insert (called Navina) to help people with faecal incontinence (accidental bowel leakage). The device is designed to be comfortable and adapt to the body to prevent leaks. Researchers compared it to usual care in 73 adults aged 16-90 to see if it improves quality of life and is cost-effective.
