Intestine: function testing

Contributor(s): Marge Chandler, Craig Ruaux, James Simpson

Introduction

  • Intestinal diseases are divided into those involving either the small or the large intestine, although some disease may affect both areas.
  • Clinical signs associated with disease of either of these two compartments are generally different.
  • Assessment of the patient allows the clinician to decide which region of the intestine is affected.
  • As the function of the small and large intestine differ, so the tests used to assess intestinal function also differ.
  • In veterinary species, it is unusual to have disease completely isolated in a single compartment, though usually one compartment dominates.
