Sacral nerve stimulation vs biofeedback for incontinence

What is known

• The only on-topic retrieved evidence is a small uncontrolled Crohn's series in which sacral nerve stimulation improved continence and quality of life ². No retrieved source reports biofeedback outcomes.

What is unknown / caveats

• Reference ¹ as retrieved is a review of medical therapy for chronic pouchitis, off-topic for this question, and does not support any statement about sacral nerve stimulation, biofeedback, or fecal incontinence treatment
• No systematic review directly comparing sacral nerve stimulation (SNS) with biofeedback for fecal incontinence and quality of life after failed sphincter preservation was retrieved, so a claim of consistent superiority of one over the other cannot be supported from this corpus
• No comparative or pooled analysis pits the two against each other.
