Answer

Colonic volvulus ranks after cancer and diverticulitis as a cause of large-bowel obstruction in the United States; it is responsible for approximately 5% of all cases of intestinal obstruction and 10-15% of all cases of large-bowel obstruction. In these populations, the most common site of large-bowel torsion is the sigmoid colon (80%), followed by the cecum (15%), the transverse colon (3%), and the splenic flexure (2%). [6]

In Western societies, the average age of patients with sigmoid volvulus is in the eighth decade, and the two sexes are equally affected. Various series have reported that of all patients diagnosed with volvulus, 25-35% are admitted to an acute care facility from a neuropsychiatric care institution, and 10-15% are admitted from a long-term nursing care facility.
