volvulus (volˑ·vy·ls),

n a condition in which a portion of the bowel slides down into its ramen. The condition is commonly due to a protrusion of a portion of the mesentery—particularly in the cecum, ileum, or the sigmoid segments of the bowel. The condition is characterized by lack of bowel sounds, nausea, vomiting, painful sensations, and a taut and swollen abdomen. If untreated, the obstructed bowel becomes necrotic and is followed by inflammation of the peritoneum and then rupture of the bowel, resulting in death.
