In contrast to sigmoid volvulus, which is usually an acquired condition, cecal volvulus is due to congenital incomplete retroperitoneal fixation of the cecum or ascending colon. In an autopsy study by Anson, over 10% of ascending colons had a mobile mesentery, permitting volvulus to occur. In a further 25% of cadavers, the cecum alone was sufficiently mobile to permit cecal bascule to occur. Further anomalies included undescended right colon, and previous surgical mobilization of the cecum, both permitting sufficient mobility for volvulus.
