Intervention Details:
  • Device: sacral nerve modulation
    electric stimulation of the sacral nerve using an implanted electrode and stimulator

Primary Outcome Measures :
  1. subjective complaint reduction [ Time Frame: 10 years ]
    Treatment is considered a success if patients report a subjective 50% reduction in disease related complaints

Secondary Outcome Measures :
  1. Rate of permanent stimulator implantations [ Time Frame: 1 month ]
    Rate of patients who finish the test phase with an external stimulator successfully (subjective reporting and 50% reduction of Wexner score for incontinence

  2. Complication rate [ Time Frame: 10 years ]
    rate of treatment related complications

  3. Rate of reoperations [ Time Frame: 10 years ]
    rate of reoperations necessary due to the treatment (e.g. electrode dislocation, electrode breakage)

  4. maintenance cost [ Time Frame: 10 years ]
    Cost incurred to maintain the treatment (e.g. relocation of electrodes, replacement of stimulator due to failure or low battery)

  5. Fecal incontinence quality of life (FIQL) [ Time Frame: 10 years ]
    Rockwood's FIQL scale

  6. Wexner Score [ Time Frame: 10 years ]
    Wexner score for fecal incontinence
