title: Is electrostimulation of the pelvic floor an effective treatment for neurogenic faecal incontinence?
abstract: BACKGROUND
  This study was designed to evaluate the results of electrostimulation of the pelvic floor for faecal incontinence.
  
  
  METHODS
  Twenty-four patients with neurogenic (n = 20) or idiopathic (n = 4) incontinence were treated on 12 occasions. Twenty were women, and the mean age was 63 years (range, 26-85 years). The result was evaluated at 3 and 12 months with a validated questionnaire and anorectal manometry.
  
  
  RESULTS
  Eleven patients (46%) reported improvement after 3 months, and the Miller's incontinence score was reduced (P < 0.01). Resting pressures, rectal compliance, and the length of the high-pressure zone were unchanged, but squeeze pressures tended to decrease. A lower threshold was seen for the rectoanal inhibitory reflex (RAIR) (P < 0.01), and the saline infusion test tended to show improved retention (P = 0.07). Nine of 13 patients followed up for 1 year claimed improvement. The most pronounced subjective improvement was seen in patients with moderate incontinence.
  
  
  CONCLUSIONS
  Electrostimulation was successful in a substantial proportion of the patients. The threshold for RAIR was lowered, and the saline infusion test tended to improve, but variables reflecting sphincter competence did not improve. Moderate incontinence was prognostically favourable, and electrostimulation might therefore be an alternative to surgery in this group.
