A Dual Benefit of Sacral Neuromodulation

Abstract

Sacral neuromodulation is a therapeutic option for women with detrusor overactivity and more recently has been used in patients with fecal incontinence and slow-transit constipation. A 47-year-old woman presented with chronic constipation since childhood. She used multiple laxatives, fiber supplements, and enemas, all without success, and defecated only once per week. Extensive investigations, including barium enema, colonoscopy, defecating proctography, pelvic magnetic resonance imaging, and anorectal manometry all were normal. A transit study showed delayed small-bowel emptying. Colonic transit could not be accurately interpreted because of the marked delayed in proximal transit. An ileostomy was being considered to defunction the colon after the patient become desperate for a better quality of life. She also complained of severe urinary frequency and incomplete emptying. A cystoscopy was normal, and a temporary sacral neuromodulation device was inserted as a staged procedure to improve her urinary symptoms. From the day of device placement and thereafter, the patient defecated without difficulty and has also been free of bladder symptoms. Repeat colonic transit has shown normalization of the stomach, small bowel, and colon.
