## Overview Small colon impaction is obstruction of the descending (small) colon by dry ingesta. Horses show mild to moderate colic, straining to defecate, and reduced or absent manure. It is less common than large-colon impaction but can be serious because of the smaller diameter. ## Causes Dehydration, poor-quality feed, or reduced water intake. ## Diagnosis Rectal palpation of a firm impaction in the small colon and clinical signs. ## Treatment Fluids, lubricants, and analgesics. Surgery if medical treatment fails or the colon is damaged. ## Recovery and Prognosis Good with timely treatment. ## Prevention Adequate water and dental care.
