Primary Outcome Measures:
  • FI - number of FI episodes per week and/or number of days with FI per week. Constipation - number of bowel movements per week; &/or decrease defecations requiring straining; &/or decrease defecations where there was incomplete emptying [ Time Frame: Annually ]

Secondary Outcome Measures:
  • FI-number of days with staining/week;urgency with continent bowel movements; Improvement in QOL;* Improvement in anal canal pressure. Constipation - Improvement in Wexner constipation score; QOL. [ Time Frame: Annually ]

Estimated Enrollment: 140
Study Start Date: November 1998
Study Completion Date: September 2012
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: InterStim therapy
Patients being treated with sacral neuromodulation with InterStim therapy.
Device: Type: Implantable neurostimulator; InterStim
Treatment with InterStim Therapy: all patients meeting inclusion/exclusion criteria undergo test screening and those who have successful outcomes receive a permanent implant.
Other Names:
  • InterStim Model 3023
  • InterStim Model 3058


Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

140 patients (7 study groups, up to 20 implanted patients per study group)

Fecal Incontinence groups:

Main Inclusion Criteria:

  • Fecal incontinence (defined as incontinence to solid or liquid stool > 1 / week);
  • Failed biofeedback or medical therapy;

Groups 1 - 5 patients with:

  • Group 1) Circumferentially intact external anal sphincter, no previous surgery;
  • Group 2) Circumferentially intact external anal sphincter after surgical repair;
  • Group 3) Rectal prolapse repaired with a rectopexy;
  • Group 4) Spinal injury including disc prolapse;
  • Group 5) Sigmoid or partial rectal resection with colorectal or coloanal anastomosis

Constipation groups:

Main Inclusion Criteria:

  • Chronic constipation (defined as </= 2 weekly bowel movements; and/or >25% of bowel movements required straining; and/or >25% of bowel movements patient did not feel empty afterwards) with symptoms more than 1 year
  • Failed biofeedback or medical therapy;

Groups 6 - 7 patients with:

  • Group 6) Idiopathic slow transit constipation as proven on colonic transit studies;
  • Group 7) Normal colonic transit studies but chronic constipation due to either pelvic floor dysfunction or disordered defecation.
