Acute colonic pseudo-obstruction/Ogilvie syndromeis a functional obstruction; it is typically seen in elderly or debilitated patients who are hospitalized with severe medical or traumatic illnesses. Medications that decrease intestinal motility are also associated with this disorder. In a retrospective review of more than 1400 cases of ACPO, the most common predisposing conditions were operative and nonoperative trauma (11%), infections (10%), and cardiac disease (10-18%).[8, 9]
