Generalized ileus is common in trauma patients. The presence of a retroperitoneal hematoma due to fractures of spine or pelvis, or other lesions, causes a reflex inhibition of peristalsis and bowel wall muscle tone. This results in generalized dilatation, particularly of the small bowel, and lack of propulsion of bowel contents. Vomiting is stimulated by vagal and sympathetic afferent nerves to the medulla oblongata. Large quantities of fluid and electrolytes continue to be secreted into the lumen of the small bowel. Protein is lost into the bowel lumen and the bowel wall, which becomes edematous. Distension of the small bowel stimulates secretion but does not enhance absorption. The contents of the large intestine may reflux through an incompetent ileocecal valve, resulting in bacterial overgrowth of the small bowel. The bowel contents produce gas which, if not discharged, leads to increased bowel dilatation. Flatus and defecation stop, leading to fecal impaction in the terminal colon and rectum.
