Large Colon Torsion is also known as Large colon Volvulus

Description

Large Colon Torsion results from the rotation of the organ about its long axis. The degree of torsion dictates the severity of clinical signs and the speed at which the condition progresses. Volvulus can occur at any point along the colon; the most common site is the junction between the caecum and the right ventral colon, and most twist in a clockwise direction, when looking at the horse from behind.

The condition can be

Signalment

Post parturient mares, large breed horses and those with a history of dietary change are at predisposed to the condition.

Diagnosis

Clinical Signs

Prognosis

Prognosis depends on the degree of volvulous and the speed of diagnosis and treatment. Torsions of 180-360° have a good prognosis as long as vascular supply is not compromised. More severe torsions and those that are stragulating,or where surgery has been delayed have a poor prognosis.
