Ogilvie syndrome

Common card · No. 441324

Ogilvie syndrome, or acute colonic pseudo-obstruction, is the acute dilatation of the colon in the absence of any mechanical obstruction in severely ill patients. Acute colonic pseudo-obstruction is characterized by massive dilatation of the cecum (diameter > 10 cm) and right colon on abdominal X-ray. It is a type of megacolon, sometimes referred to as "acute megacolon," to distinguish it from toxic megacolon. The condition carries the name of the British surgeon Sir William Heneage Ogilvie (1887–1971), who first reported it in 1948. Ogilvie syndrome is an acute illness, which means it occurs suddenly and temporarily, and it only affects the colon. "Intestinal pseudo-obstruction" is a broad term that refers to any paralysis of the intestines that is not caused by a mechanical obstruction. Some individuals develop chronic intestinal pseudo-obstruction as a result of a chronic disease or a congenital condition.
