Caeco-Caecal Intussusception - Horse

Description

Caeco-caecal intusssception results from uncoordinated peristalsis allowing the apex of the caecum to invaginate into the base. It is a fairy rare cause of colic, accounting for only 3-5% of caecal disease in the horse.

Signalment

Predisposing factors include caecal abscesses, motility-affecting drugs and parasites including Cyathostome species and Anoplocephala.

Diagnosis

Clinical Signs

• Adbominal pain
• Pyrexia
• Tachycardia
• Colic signs

Severity of clinical signs depend on the duration of the intussusception and the degree of cardiovascular compromise, ischemia and toxaemia resulting from the condition. Early diagnosis is important.

If the intussusception is associated with parasite infestation then there will likely be additional clinical signs of weight loss, diarrhoea and

Diagnosis can be made on rectal examination in some cases; the base of the caecum is thickened and oedematous, and firmer than usual. In other cases caecal involvement can be identified on rectal palpation but definitive diagnosis of intussusception is made at laparotomy under general anaesthesia.
