Volvulus occurs most frequently in middle-aged and elderly men. [11] Volvulus can also arise as a rare complication in persons with redundant colon, a normal anatomic variation resulting in extra colonic loops. [12] Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract.
In men, mobilization of the rectum may risk the development of erectile dysfunction. [9] Another way of categorizing surgery for prolapse of pelvic organs is suspensive or resective (involving removal of sections of the bowel wall). Ventral rectopexy alone is a syspensive type surgery, a category which also includes colposacropexy. [10]
The sigmoid colon (or pelvic colon) is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 35–40 centimetres (14–16 in) in length. It forms a loop that averages about 35–40 centimetres (14–16 in) in length.
The transverse colon is the part of the colon from the hepatic flexure, also known as the right colic, (the turn of the colon by the liver) to the splenic flexure also known as the left colic, (the turn of the colon by the spleen). The transverse colon hangs off the stomach, attached to it by a large fold of peritoneum called the greater omentum.

Women over 50 are six times more likely to develop rectal prolapse than men. It is rare in men over 45 and in women under 20. [ 21 ] When males are affected, they tend to be young and report significant bowel function symptoms, especially obstructed defecation , [ 5 ] or have a predisposing disorder (e.g., congenital anal atresia ).

[17] [18] If blood flow to the colon drops by more than about 50%, ischemia will develop. The arteries feeding the colon are very sensitive to vasoconstrictors; presumably this is an evolutionary adaptation to shunt blood away from the bowel and to the heart and brain in times of stress. [19]
