Equine Surgeon Jose J. Bras, DVM, MS, Dipl. ACVS was one of the speakers during our evening of Cocktails and Conversations in Wellington where he covered diagnosis and surgical decisions for horses with Colic. Colic in horses is defined as abdominal pain, but it is a clinical sign rather than a diagnosis. The term colic can encompass all forms of gastrointestinal conditions which cause pain as well as other causes of abdominal pain not involving the gastrointestinal tract. The most common forms of colic are gastrointestinal in nature and are most often related to colonic disturbance. There are a variety of different causes of colic, some of which can prove fatal without surgical intervention. Colic surgery is usually an expensive procedure as it is major abdominal surgery, often with intensive aftercare. Clinical signs of colic generally require treatment by a veterinarian.
