==Diagnosis==

Diagnosis of intussusception in the horse may be difficult as [[abdominocentesis]] rarely reveals any abnormalities. This is due to the strangulated portion of gut being contained within the intussuscipiens. In the case of jejuno-jejunal intussusceptions, rectal examination may reveal a sausage-shaped, tubular structure in the mid abdomen of the horse. The presence of melaena is a significant finding and may raise clinical suspicion of intussusception. [[Colic Diagnosis - Abdominal Ultrasound|Abdominal ultrasonography]] may reveal a characteristic target or 'bulls-eye' lesion on transverse section. Peristalsis in the affected segment is reduced or absent. Oedema and thickening (>3mm) of the intestinal wall are often seen with a distended, fluid-filled region proximal to the intussusception.

Definitive diagnosis, however, is often based on findings at laparotomy.
