Answer

Whereas sigmoid volvulus is usually an acquired condition, cecal volvulus is due to congenital incomplete dorsal mesenteric fixation of the cecum or ascending colon associated with an abnormally elongated mesentery distal to this area of absent mesentery. In autopsy studies, marked mobility of the right colon occurs in an estimated 15-20% of the population.
