Clinical sigs are of simple small intestine obstruction. There will be additional signs of parasite infestation is cases associated with ascarid and tapeworm infection.
Clinical sigs are of simple small intestine obstruction. There will be additional signs of parasite infestation in cases associated with ascarid and tapeworm infection.
The severity and speed on onset of clinical signs is determined by the level of the obstruction. Proximal obstructions will progress more rapidly than distal ones.
The severity and speed on onset of clinical signs is determined by the level of the obstruction. Proximal obstructions will progress more rapidly than distal ones.
Passage of a stomach tube will produce nasogastric reflux depending on the site of obstruction and its duration; for a proximal obstruction fluid will build up in the stomach after approximately 3-6 hours, and for a distal obstruction, after 12 hours.
'''Passage of a stomach tube''' will produce nasogastric reflux depending on the site of obstruction and its duration; for a proximal obstruction fluid will build up in the stomach after approximately 3-6 hours, and for a distal obstruction, after 12 hours.
'''Gut sounds''' will decrease as the small intestine becomes distended and atonic.
On [[Rectal Examination of the Horse|rectal examination]] the small intestine is palpable as distended loops; in the early stages of ileal impaction a tubular structure may be felt in the mid abdomen.

Surgical management is recommended for small instenstine impaction. A ventral midline laparotomy is carried out to gain access to the small intestine and assess
