title: [Sacral nerve stimulation treatment in functional anorectal pain].
abstract: OBJECTIVE
  To evaluate the treatment outcomes of sacral nerve stimulation(SNS) for functional anorectal pain(FAP).
  
  
  METHODS
  A total of 32 patients of FAP received SNS treatment through S3 from March 2011 to December 2011. Visual analogue scale(VAS), anal pressure measure, and health survey(SF-36) before and after treatment were used to evaluate the outcomes.
  
  
  RESULTS
  After treatment, VAS score was significantly decreased, rectal anal reflex threshold volume elevated, and anal maximum contraction pressure (AMCP) and anal rest pressure significantly decreased compared with those before treatment(all P<0.01). Except for general health, the remaining dimension score of the SF-36 increased significantly after treatment, and the differences were statistically significant(P<0.05 or P<0.01). After SNS treatment, 19 cases were cured, 12 improved, 1 was refractory. The total effective rate was 96.9% during 3 months after treatment.
  
  
  CONCLUSIONS
  SNS is a safe and effective alternative for FAP and can alleviate the pain symptom and improve the quality of life.
