Ileal intussusception in 16 young thoroughbreds.

Abstract

The paper describes the outcome of 16 cases of short-ileal-ileal intussusception in young Thoroughbred horses. The intussusception was often associated with chronic or intermittent low grade abdominal pain. At laparotomy, only the intussusception was reduced in one horse; in another, a myotomy of the thickened stenosed intussusception was carried out after reduction. In 11 cases as ileocaecal bypass anastomosis was performed proximal to the intussusception after its reduction. One horse was subjected to euthanasia during operation because of irreversible intestinal wall damage and another because of intestinal rupture. One foal had a cardiac arrest following reduction of the intussusception. One horse was subjected to euthanasia 4 months post-operatively because of intractable abdominal pain caused by intestinal adhesions. Although several horses suffered episodes of post-operative abdominal pain, and 2 were subjected to a second laparotomy, 12 horses made an eventual complete recovery.
