Sacral nerve stimulation (SNS) has over the last 20 years been recognised as an efficient treatment option for faecal incontinence (FI). The therapy is recommended by the International Continence Society (ICS) if conservative treatments such as; regulation of diet and fibre supplements, medication, biofeedback therapy, glycerol suppositories, mini enema or transanal irrigation have been insufficient to improve continence to a satisfactory level.
