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

Treatment

Prognosis
Prognosis depends on the degree of volvulous and the speed of diagnosis and treatment. Torsions of less than 270° have a good prognosis, for more severe torsions, those that are stragulating, or in cases where surgery has been delayed, the prognosis is poor.
