Different from other types of impaction in predispositions and clinical appearance(BLiks)

Impaction of the descending colon is seen in ponies, miniature horses, and adult horses with limited access to drinking water or with other causes of intestinal stasis. Most recently, the condition has been associated with salmonellosis, although a cause and effect relationship has not been proved. Pain may be severe if the obstruction is complete. In such cases, tympany of the colon occurs secondarily, and ileus results. Foreign body obstruction of the descending colon must be considered if the horse is <3 yr old; the offending material may be rubber fencing, nylon fibers from halters or lead shanks, hay net, or feed sacks.
