Disorders of Motility Disorders of Motility Intestinal Obstruction and Ileus
◦“Caused by any condition that prevents the normal flow of chyme through the intestinal lumen or failure of normal intestinal motility in the absence of an obstructing lesion” (McCance, K.L., Huether, S.E., Brashers, V.L., & Rote, N.S., 2010, p 1460).
