AbstractIrritable Bowel Syndrome (IBS) is a functional gastrointestinal (GI) disorder, characterized by abdominal pain, altered bowel habit (diarrhea and/or constipation), and bloating in the absence of demonstrable organic pathology. It is the most common GI disorder seen in primary care and gastroenterology practices. Conservative therapies for IBS are directed at both pain and correction of altered GI motility. A small proportion of patients with IBS have severe or refractory symptoms and report constant pain. IBS is no longer considered solely a disorder of motility, but rather its clinical expression is viewed as dysregulation of CNS-enteric function. Symptoms of IBS cannot be explained entirely by changes in motility alone and may also arise from complex feedback and feed-forward interactions between supraspinal circuits, the spinal cord, and the periphery, in effect, a neuropathic process, that might be amenable to neuromodulation, that is, spinal cord stimulation. We present here a single case report of a patient with IBS who responded positively to SCS after failing all conservative therapies to alleviate or manage her abdominal pain and diarrheal episodes. Our discussion is focused on the reasons why SCS might work in patients with IBS.
