Is a rotation of the dorsal and ventral colon in its longitudinal axis. The insertion point of these structures is the mesenteric root, and this is the most common location of the process: the right dorsal colon is displaced laterally and ventrally rotated and right ventral colon is displaced medially and rotates dorsally.

The cecum may be involved in the "screwing" and the large colon and cecum can rotate together around the vertical axis of mesentéreo.

Etiology

The exact cause is unknown although it is thought that the hypomotility due to pain or electrolyte abnormalities, causes gas distension of the colon and result in the displacement of the ventral colon (larger) on the dorsal colon (smaller).

Symptoms

High frequency affects primarily pregnant females after delivery. Furthermore, the risk increases with age. The onset is rapid, with virtually uncontrollable pain. There is tachycardia and anxiety that are kept by the obstructive shock. The mucous membranes may be normal or slightly pale due to vasoconstriction and decreased venous return. As relaxation occurs, there is dyspnea, which may even cause respiratory acidosis. An increase in total protein in peritoneal fluid is a reflection of a poor prognosis.

Treatment

Is surgical and if the affected portion of colon is not viable, is necessary the intestinal resection or euthanasia. Overall the prognosis is poor, and survival depends on rapid diagnosis and appropriate surgical correction. We can get a high percentage of success if the surgery takes place within two hours after the onset of pain.
