La stimulation nerveuse sacrée, traitement efficace de l'incontinence fécale [Sacral nerve stimulation, an effective treatment for fecal incontinence]

Sacral nerve stimulation (SNS) became recently an essential therapeutic modality in the treatment of anal incontinence. Indications range from anorectal functional disorders to limited sphincteric lesions. An electrode is inserted through a sacral foramen, generally S3, to stimulate the corresponding nerve root. Patient's selection needs a meticulous multidisciplinary approach. Improved continence of more than 50% is frequently encountered and quality of life is significantly improved after implantation. SNS is a minimal-invasive technique, with very few risks of complications.
