'''Small Instestinal impaction''' causes total or partial obstruction of the instestinal lumen resulting in [[Category:Colic in Horses|colic]]. The obstruction is most often associated with [[Ascarid Impaction - Horse|ascarid impaction]] due to ascarid infection<ref>Cribb NC, Cote NM, Bouré LP, Peregrine AS. (2006). ''Acute small intestinal obstruction associated with Parascaris equorum infection in young horses: 25 cases (1985-2004).''. New Zealand Veterinary Journal</ref> in young horses, or ileal impaction due to ingestion of bermuda grass in the USA or tapeworm infection in the UK.

Ingesta and fluid builds up proximal to the impaction and does not reach the absorbative large intestine, this results in systemic volume depletion and reduced cardiac output. 

Impaction may also result due to postoperative ileus; the risk can be minimised by good surgical technique, appropriate postoperative care and the adminstration of prokinectic drugs.
