Small bowel motility is a highly coordinated process of mixing, absorption and propulsion of ingesta throughout the gastrointestinal tract, eventually leading to the expulsion of residues. This complex series of processes results from the activity of the enteric nervous system to digestive smooth muscle and pacemaker activity evoked by the interstitial cells of Cajal. Abnormality in any of these components will result in dysmotility. Recently, several newer diagnostic tools and findings have highlighted our understanding of small bowel motility. At the era of neurogastroenterology, this review outlines the current understanding of the causes, pathophysiology, diagnostic evaluation, and classification of motility disorders of the small intestine.
