Answer

The presence of a long mesentery with a narrow base of fixation to the retroperitoneum and elongated, redundant bowel predisposes to the formation of volvulus. Volvulus can develop in any portion of the large bowel. However, it is most common in the sigmoid colon because of the mesenteric anatomy. Less commonly, volvulus develops in the right colon and terminal ileum (cecal or cecocolic volvulus) or the cecum alone (termed a cecal bascule). In rare cases, volvulus may develop in the transverse colon or the splenic flexure.
