==Description==
==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 caecal obstruction in the horse and represents only a small proportion of colic cases.
'''Caeco-caecal intussusception''' results from uncoordinated peristalsis allowing the apex of the caecum to invaginate into the base. It is a fairy rare cause of [[:Category:Colic in Horses|colic]], accounting for only 3-5% of caecal disease in the horse.

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

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 in some cases ventral oedema.
Diagnosis can be made on [[Rectal Examination of the Horse|rectal examination]] in some cases; the base of the caecum can be palpated in the right caudal abdomen, it is thickened, 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.

==Treatment==
==Treatment==
Treatment is by surgical reduction of the intussusception at laparotomy under general anaesthesia. The caecum must be closely inspected; a partial or total tylephectomy may need to be performed if the tissue is severely damaged or if the intussusception cannot be reduced.
IV fluid therapy and flunixin meglumate should be administered.
