The epiploic foramen is located in the right dorsal abdomen and is bordered by the vena cava, hepatic portal vein, liver and pancreas. Most incarcerations are caused by small intestine passing from the left side of the abdomen through the epiploic foramen to the right side of the abdomen. The ileum and the jejunum are the most commonly incarcerated portions of small intestine and the length of bowel affected may vary from a few centimetres to 17m. Strangulation of the affected portion occurs as a result of entrapment in the majority of cases and approximately 80% of affected horses have irreversible vascular compromise of the herniated small intestine.
