===Description===
===Description===
A small intestinal volvulus occurs in the horse when the intestine rotates on its mesenteric axis through an angle greater than 180<sup>o</sup>, resulting in strangulation. Volvulus may occur as a primary cause of colic or secondarily as a result of another condition
A small intestinal volvulus occurs in the horse when the intestine rotates on its mesenteric axis through an angle greater than 180<sup>o</sup>, resulting in strangulation. Volvulus may occur as a primary cause of colic or secondarily as a result of another condition such as epiploic foramen entrapment, incarceration within the mesentery or adhesion within the abdomen.
===Signalment===
===Signalment===
Foals and yearlings seem to be particularly susceptible to this type of colic.
Foals and yearlings are particularly susceptible to this type of colic.
===Clinical signs===
===Clinical signs===
The clinical signs associated with this condition are both acute and severe. Common signs include:
* Severe, unrelenting abdominal pain that is non-responsive to analgesia
* Severe, unrelenting abdominal pain that is non-responsive to analgesia
* Tachycardia
* Tachycardia
===Treatment===
===Treatment===
Treatment for this condition is surgical and consists of correction of the volvulus via a ventral midline coeliotomy. Following reduction of the volvulus, nonviable bowel is resected and an end-to-end anastamosis is performed.
===Prognosis===
===Prognosis===
The prognosis associated with small intestinal volvulus is poor due to the rapid cardiovascular deterioration associated with the condition. Previous authors have reported that euthanasia should be considered if greater than 50% of the small intestine requires resecting.
