DB30.1 Volvulus of large intestine

International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2025-01

A volvulus is an abnormal twisting of the intestine around the axis of its own mesentery, resulting in obstruction of the more proximal bowel. Twisting of the mesentery may involve the mesenteric vessels and so make the involved loop particularly susceptible to strangulation and gangrene, with resulting perforation, peritonitis, and sepsis. The classical sites of large intestinal volvulus are the caecum and the sigmoid colon, although there are reports of volvulus of the transverse colon and the splenic flexure.
