Intestinal malrotation and volvulus

From WikiLectures

Malrotation means a malfunction in the rotation of the intestine or a malfunction in its attachment to the back wall of the abdomen. A normal intestine rotates counterclockwise. The superior mesenteric artery acts as the axis of rotation. An unfixed bowel predisposes to volvulus (knotting of the bowel hinge) and obstruction. It is sometimes associated with asplenism or congenital heart defects.
