Fecal Incontinence · Conservative vs Sphincteroplasty vs Sacral Neuromodulation

Step-by-step decision

Choose step by step as prompted; reaching an endpoint gives the management recommendation. You can go back a step or restart anytime.

Full pathway

1. [Decision] Conservative response + sphincter defect
   Conservative therapy failed? Clear sphincter defect?
   • Newly diagnosed/not adequately treated conservatively → First-line → conservative
   • Conservative failure, clear sphincter defect (obstetric, etc.) → Sphincter defect → sphincteroplasty
   • Conservative failure, no clear defect or failed repair → No defect/failed → sacral neuromodulation
   • Refractory severe/all of the above failed → Refractory severe → last-resort procedures
2. [End] First-line → conservative
   First-line conservative: dietary fiber/antidiarrheal (loperamide), regular bowel habit, pelvic floor muscle training/biofeedback; most improve.
3. [End] Sphincter defect → sphincteroplasty
   Conservative failure + clear sphincter defect (obstetric injury) → sphincteroplasty (overlapping repair); long-term efficacy may wane, can combine with SNM.
4. [End] No defect/failed → sacral neuromodulation
   Conservative failure, no clear defect or failed repair → sacral neuromodulation (SNM, with a trial stimulation first); an effective first-line surgical option; mild/passive incontinence may have a bulking agent injection.
5. [End] Refractory severe → last-resort procedures
   Refractory severe/all methods failed → artificial bowel sphincter, antegrade continence enema (ACE), or colostomy (a last resort to improve quality of life).
