have chosen colon resection or a different colopexy technique, but incorporation of the colon into the ventral midline is almost certainly the fastest technique. Randomised clinical trials to compare colopexy techniques would be challenging due to surgeon preference, individual case considerations, and limited large colon volvulus cases at many hospitals. However, biomechanical analysis and retrospective data on colopexy in larger populations of non- broodmare horses would be valuable contributions to decision-making in equine large colon volvulus cases.
