- Abstract
Background: Numerous studies advocate the short-term benefits of sacral nerve stimulation for fecal incontinence, but there has been a paucity of studies on longer-term outcomes., Objective: The objective of this study was to report the long-term outcome of sacral nerve stimulation performed for fecal incontinence at a single institution., Patients and Design: Between January 2004 and May 2007, 53 patients underwent definitive sacral nerve stimulation for fecal incontinence at our institution. Prospectively recorded baseline information, including Wexner incontinence scores and standard short-form (SF-12) health survey scores, were compared with scores at follow-up., Results: Forty-one patients were available for long-term follow-up with a mean duration of 51 months. The median Wexner score decreased from a baseline of 11.5 (range, 3.0-18.0) to 8.0 (range, 0.0-18.0) at follow-up. The mean difference in Wexner score was 2.7 (P < .001). There was no statistically significant change in SF-12 physical scores, but a small but highly significant change occurred in SF-12 mental scores. The median SF-12 mental domain score was 49.5 (range, 15.0-62.1) at baseline, and 57.0 (range, 20.0-64.0) at follow-up, with a mean difference of 4.5 (P = .006). Subgroup analysis performed comparing patients with or without prior intersphincteric silicon biomaterial implants demonstrated a mean difference in Wexner score of -3.5 (no implant) vs 0.0 (previous implant), with P < .09 (not statistically significant)., Conclusions: Sacral nerve stimulation results in a statistically significant improvement in fecal incontinence scores in the long term.
