What is the least invasive treatment option for fecal incontinence?

• A. Sacral nerve modulation
• B. Antidiarrheal medication
• C. Colostomy
• D. Anorectal manometry

Answer: (A)

Fecal incontinence management is about finding a balance between how invasive a therapy is and how well it controls symptoms. Sacral nerve modulation works by delivering gentle electrical stimulation to the nerves that control the pelvic floor and anal sphincter. This helps improve continence without altering bowel anatomy, and it’s done through a small implanted device that can be adjusted or removed if needed. Because it avoids permanent changes to the bowel and is reversible, it sits at a lower invasiveness level compared with major surgeries like creating a colostomy, and it is more durable than simple, ongoing medical therapy.

Antidiarrheal medicines are non-invasive, but they manage stool consistency rather than restoring continence and may not be sufficient for many patients. Anorectal manometry is a diagnostic test, not a treatment. A colostomy is a major, permanent alteration of bowel function. So, among the options, sacral nerve modulation offers a minimally invasive, adjustable, and reversible approach that can provide meaningful and lasting continence improvement.
