DA91.1 Volvulus of small 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.
