epiploic foramen, Borders: caudate lobe of the liver, the inferior vena cava, hepatic portal vein and the pancreas.

A piece of small intestine can become trapped through the epiploic foramen entrapment. The blood supply to this part of the intestine is immediately occluded. The intestine becomes trapped and surgery is the only available treatment. In a short amount of time (hours) the horse can enter a irreversible shock state so the veterinarian needs to asses the pain level and the clinical signs to refer for surgical intervention in the early stages. When caught at an early stage there is a 69% success rate for discharge from the hospital.

The most common internal hernia that causes colic in the horse.

Associated to cribbing and stabling the horse a month previous to the incident.
