Botox shots for bowel control: a new hope for fecal incontinence?
NCT ID NCT02414425
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether injecting botulinum toxin (like Botox) into the rectum can reduce episodes of accidental bowel leakage and urgent bathroom needs in people with fecal incontinence. The trial involved 200 adults whose condition did not improve with standard treatments. The goal was to see if these injections could improve quality of life with few side effects, though any benefits are expected to be temporary.
