==Description==

'''Intestinal obstruction''' can be classified as acute or chronic, partial or complete, simple or incarcerated.  The cause of the obstruction can be intraluminal, extraluminal or intramural.  Most common causes of intestinal obstruction include intussusception, neoplasia and foreign body.  Intussusception is more likely in young animals with a history of gastroenteritis or intestinal surgery.  Cats frequently present with linear foreign bodies.  Other less common causes include intestinal torsion/volvulus and incarcerated intestinal obstruction.  Neoplasia is more commonly present in middle-aged to older animals.

===Clinical Signs===

The clinical presentation depends on the cause, severity, and the site of obstruction.  Upper small intestinal obstruction causes a net fluid secretion whereas lower small intestinal obstruction causes a net fluid resorption.  Antibiotic responsive diarrhoea is more likely to occur in distal small intestinal obstruction.
