'''Caecal impaction''' in horses occurs in two forms. In '''primary impactions''' the caecum contains dry, relatively solid ingesta which may be localised to the cranial part of the caecal base, or extend to fill the whole viscera. The onset of [[Colic Diagnosis - Clinical Signs|clinical signs]] is typically 5-7 days and the associated signs are of low grade intermittent colic. | '''Caecal impaction''' in horses occurs in two forms.
