volvulus

[′väl·vyə·ləs]
(medicine)
A twisting of the bowel upon itself so as to occlude the lumen and, in severe cases, compromise its circulation.

Volvulus

 

acute intestinal obstruction, twisting of part of the intestine and mesentery with blockage of the blood circulation from the root of the mesentery to the intestinal lumen.

Volvulus may result from the intestine twisting around its own axis, with the mesentery around the mesenteric axis, or with the mesentery around another intestinal loop (for example, loop of the small intestine with the mesentery around the sigmoid colon). The latter leads to knotting, or intestinal loops that are difficult to untie.
