==Diagnosis==
Affected horses may have a history of living in a sandy environment, grazing in dry weather or a reduction in water intake. Auscultation of the abdomen may reveal gritty-sounding 'rubs' heard as the sand moves through the colon. Definitive diagnosis of an impaction is made via [[Rectal examination of the Horse|rectal palpation]] or transrectal ultrasonography. In many cases however the impacted segment is located in the cranial gastrointestinal tract and is therefore out of reach. Sand also may be seen in the faeces by mixing faecal material with water in a plastic rectal examination sleeve and allowing the sand to fall to the bottom. If performed, [[abdominocentesis]] should be carried out with extreme caution in order to avoid inadvertent laceration of the sand-impacted colon. Abdominal radiography may be useful in assessing the volume and location of sand impaction in foals, miniature horses and small ponies.
