Volvulus

Twisting of a loop of intestine or, in rare cases, of the stomach. Volvulus is a serious condition that causes obstruction of the passage of intestinal contents (see intestine, obstruction of) and a risk of strangulation. If strangulation occurs, blockage of blood flow to the affected area leads to potentially fatal gangrene. The symptoms of volvulus are severe episodes of abdominal pain followed by vomiting. Volvulus may be present from birth or may be a result of adhesions. It requires emergency treatment, usually by surgery.
