Sacral nerve modulation has been proven to be effective for fecal incontinence and improves quality of life.

• A. True
• B. False
• C. Not proven
• D. Unknown

Answer: (A)

Sacral nerve modulation, also known as sacral neuromodulation, delivers targeted electrical stimulation to the sacral nerves to recalibrate the neural control of the pelvic floor and anorectal function. This modulation helps coordinate the anal sphincter, improves rectal sensation, and reduces inappropriate rectal contractions, which together lower fecal incontinence episodes and enhance continence.

The statement is supported by a robust body of evidence. Multiple studies, including randomized trials and long-term follow-ups, show meaningful reductions in incontinence episodes and improvements on quality-of-life measures compared with baseline and, in some designs, with sham or conventional therapy. Benefits often persist for years, with many patients achieving substantial or near-complete continence and notable QoL gains. Because of this, sacral nerve modulation is recognized as a proven option for adults with fecal incontinence who have not had sufficient relief from conservative treatments. While not every patient experiences the same level of benefit, the overall data support its effectiveness and impact on quality of life.
