Neuromodulation is a validated option for the treatment of fecal incontinence. Safety of this original approach has been confirmed by several studies. New indications for this minimally-invasive procedure are actually under evaluation particularly in the fields of irritable bowel syndrome and chronic constipation with promising results. Its mechanism of action remains partially unknown and the target of neuromodulation is not limited to the anal sphincter but the whole colonic motility seems to be influenced by this therapeutic approach. Moreover, recent experimental studies have shown that neuromodulation was able to reinforce the intestinal epithelial barrier involved in the pathophysiology of ulcerative colitis.
