Gastroscopy & Endoscopy

Gastroscopy in horses is a diagnostic procedure used to examine the upper gastrointestinal tract, specifically the oesophagus, stomach, and the entrance to the small intestine. This is most commonly employed to diagnose equine gastric ulcer syndrome (EGUS), which is a prevalent condition in performance horses and those under stress from factors like intense exercise or frequent travel. The procedure involves passing a flexible video endoscope, typically about three meters long, through the horse’s nostril and down the oesophagus into the stomach. The video camera allows the vet to visually examine the stomach lining, identifying ulcers, inflammation, or other abnormalities that could affect the horse’s health and performance.

Before a gastroscopy, the horse must be fasted, typically for 8 – 10 hours, to ensure the stomach is empty and provides a clear view of the stomach lining. Sedation is often administered to keep the horse calm and still during the procedure. Gastroscopy is highly valuable because it offers a definitive diagnosis, allowing targeted treatment plans, such as dietary changes, stress management, and medications.
