Does Rectoanal Intussusception Limit Improvements in Clinical Outcome and Quality of Life After Sacral Nerve Stimulation for Fecal Incontinence?

Abstract

BACKGROUND: Sacral nerve stimulation is a treatment option for severe, medically refractory fecal incontinence, although its use in patients with anatomic abnormalities remains controversial. OBJECTIVE:This study aimed to determine whether patients with rectoanal intussusception achieve similar benefits from device implantation to patients without rectoanal intussusception. DESIGN:Retrospective review of a prospectively maintained database. Demographics and clinical data were collected for each patient, including preoperative pelvic floor testing. Defecographies were reanalyzed in a blinded manner. Preoperative rectoanal intussusception was determined on the basis of the Oxford system (grade III-IV vs not; grade V excluded).SETTINGS: Academic-affiliated pelvic health center.
