Paralytic ileus

**Definition:** A type of ileus, a functional not mechanical obstruction of the small intestines, and a state of pathophysiologic inhibition of motor activity due to non-mechanical causes. The paralysis does not need to be complete, but the intestinal muscles must be so inactive that it leads to a functional blockage of the intestine.

**Exclusions:** - Gallstone ileus of small intestine - Obstructive ileus of small intestine due to impaction
