==Introduction==
'''Right dorsal displacement''' of the large colon is a cause of colic in horses. It is much less common than [[Large Colon, Left Dorsal Displacement - Horse|left dorsal displacements]] and although clinical signs can be variable, it is usually more acute and serious in presentation. In all cases the left dorsal and ventral large colon displace to sit between the caecum and the right body wall. The pelvic flexure is usually displaced cranially towards the diaphragm; the caecum is shifted towards the midline and may become secondarily distended. In some cases the displacement is accompanied by a volvulus which is responsible for more acute presentation. The exact cause of the condition is not known.

If the condition is identified early and surgical correction is carried out without delay then the prognosis is very good. In cases where the vascular supply to the colon has been compromised the prognsis is much worse.
