Medical Treatment of Colic in Horses
Description
Impaction of the large colon is seen in horses with limited access to drinking water or grazing bare pastures. The sand is not ingested but accumulates within the right dorsal colon, pelvic flexure and transverse colon. Due to its high density, the sand forms a sediment within the colon
Clinical signs
Clinical signs are generally dependent on the site of impaction Horses affected by a pelvic flexure impaction often present with signs of mild abdominal pain and generally respond well to conservative treatment. Impaction of the transverse colon is often associated with more severe abdominal pain due to the build up of gas in the the colon proximal to the obstruction.
Diagnosis
Affected horses may have a history of living in a sandy environment, grazing in dry weather or reduced water intake. Definitive diagnosis is made via rectal palpation and identification of sand in the dorsal colon. Transrectal ultrasonography may assist in identifying the presence of sand. Sand also may be seen in the faeces by mixing faecal material with water in a plastic rectal examination sleeve.
