## Overview Jejunal intussusception is telescoping of one segment of jejunum into an adjacent segment, causing obstruction and compromised blood supply. It is more common in young horses and may be associated with parasites or enteritis. Ultrasound often shows a target-like lesion, and horses present with acute colic and reflux. ## Causes Altered motility from parasites, enteritis, or other factors allowing one segment to invaginate into another. ## Diagnosis Acute colic, nasogastric reflux, distended small intestine, and the characteristic target lesion on ultrasound. Confirmed at surgery. ## Treatment Surgical reduction or resection of the affected bowel. Time is critical to preserve intestinal viability. ## Recovery and Prognosis Fair if operated before irreversible damage. Delayed cases have higher mortality. ## Prevention Parasite control may reduce one risk factor.
