PURPOSE:
Fecal incontinence is a psychologically devastating and socially incapacitating condition. Conventional treatment is likely to improve continence in many patients; however, there remains a group with persisting symptoms who are not amenable for a simple surgical repair. We evaluated the effect of sacral neuromodulation in patients with structurally intact sphincters after failure of conventional treatment.
METHODS:
Patients aged 18 to 75 years were evaluated. Incontinence was defined as involuntary loss of stool at least once per week, which was objectified by completion of a three-week bowel-habits diary during ambulatory electrode stimulation at the S3 or S4 foramen. Patients were qualified for permanent stimulation when showing a reduction of at least 50 percent in incontinence episodes or days.
RESULTS:
Seventy-five patients (66 females; mean age, 52 (range, 26–75) years) were treated. Three patients had partial spinal cord injury, two patients a previous low-anterior resection, and nine patients had a previous sphincter repair. Evaluation after trial screening showed that 62 patients (83 percent) had improved continence. Median incontinence episodes per week decreased from 7.5 to 0.67 (P < 0.01), median incontinence days per week from 4 to 0.5 (P < 0.01). The symptomatic response stayed unchanged after implantation of a permanent electrode and pacemaker in 50 patients. After a median follow-up of 12 months, this effect could be sustained in 48 patients. Anal manometry during stimulation showed no increase of sphincter pressures.
CONCLUSIONS:
Sacral neuromodulation is a feasible treatment option for fecal incontinence in patients with structurally intact sphincters.
