Effect of sacral anterior root stimulator on bowel dysfunction in patients with spinal cord injury
Abstract
Purpose Bowel dysfunction is a problem in patients with spinal cord injury. The sacral anterior root stimulator has been used for neurogenic bladder and has been claimed to be useful for neurogenic bowel. The purposes of this study were to analyze the clinical response of bowel function to the sacral anterior root stimulator and to evaluate physiologic factors that could determine its efficacy. Methods Eighteen consecutive patients with spinal cord injury and an implanted sacral anterior root stimulator were evaluated. Clinical assessment, colonic transit time, and anorectal manometry were performed. Patients were evaluated before implantation of the sacral anterior root stimulator and clinically reevaluated after 12 months. Results Fewer patients required laxatives after implantation of the sacral anterior root stimulator. The mean number of methods used to evacuate was reduced from 2.1 to 1.5 (P Conclusion The sacral anterior root stimulator improves bowel function, and patient satisfaction with this treatment is high. Further studies are needed to evaluate the characteristics of stimulation parameters to achieve better results.

In selected patients with spinal cord injury, computerized stimulation of the sacral anterior roots may improve pelvic colonic and anorectal sphincter function, generally in conjunction with S2-S4 posterior sacral rhizotomy to reduce the risk of autonomic dysreflexia.
“In selected patients, computerized stimulation of the sacral anterior roots may improve pelvic colonic and anorectal sphincter function, generally in conjunction with S2–S4 posterior sacral rhizotomy to reduce the risk of autonomic dysreflexia (Rasmussen et al., 2015; Valles et al., 2009).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
