Answer

Other anomalies that predispose to cecal volvulus include undescended right colon and previous surgical mobilization of the cecum, both permitting sufficient mobility for volvulus. Appendicitis, with resultant formation of adhesions, predisposes to cecal volvulus as well.

As in sigmoid volvulus, a pelvic space-occupying lesion (eg, a gravid uterus or an ovarian tumor) may precipitate an episode of cecal volvulus by altering the relative positions of the intra-abdominal organs. Gaseous dilation of the sigmoid colon and cecum after colonoscopy has also been described as a cause of volvulus.
