title: Value of sacral nerve stimulation in the treatment of severe faecal incontinence: a comparison to the artificial bowel sphincter.
abstract: OBJECTIVE
  Sacral nerve stimulation (SNS) is a recent treatment option in the management of severe faecal incontinence (FI) that offers promising results. The aim of this study was to compare SNS to artificial bowel sphincter (ABS) implanted patients to assess the rationale of this approach in achieving satisfying functional results and improved quality of life (QoL).
  
  
  METHODS
  Among 27 patients tested (December 2001 and April 2004), 15 patients were successfully managed with SNS. They were compared to 15 matched patients implanted with ABS in a previous period (control group). Assessment of continence level (Cleveland Clinic score), constipation score (Knowles, Eccersley, Scott Score) and QoL (Short-Form 36) were prospectively collected.
  
  
  RESULTS
  Both groups were comparable for clinical parameters (age, gender, anal testing and aetiology of incontinence) and anal physiology. The mean postoperative continence score was significantly higher in the SNS group [9.4 (+/-3.3) vs 5.7 (+/-3.9), P < 0.01]; however, the mean constipation score was higher in the ABS group (6.3 +/- 6.3 vs 12.8 +/- 5.7, P < 0.01). The mean QoL score was similar in both groups. The mean follow-up after implantation was 15 (+/-9) months in the SNS group, and 43 (+/-33) months in the ABS group.
  
  
  CONCLUSIONS
  In this study, SNS offers satisfying results in terms of QoL, similar to that of ABS. Although it seems to be less effective in restoring continence level, symptoms of outlet obstruction are more frequent after ABS. This SNS approach should be proposed as a first-line treatment of FI in selected patients. ABS should remain an option that can improve function.
