Gastroscopy

Gastroscopy is an essential diagnostic tool for the identification of Equine Gastric Ulcer Syndrome (EGUS) and Equine Glandular Gastric Disease (EGGD), a common cause of poor performance, weight loss, reduced appetite, and resistance to ridden work. It is the only reliable method to directly visualise the stomach and proximal duodenum, allowing accurate diagnosis and grading of gastric disease.

Gastroscopy involves passing a long endoscope through the horse’s nose, down the oesophagus, and into the stomach. Our 3.5m digital gastroscopes allow full visualisation of the stomach lining and the first part of the duodenum. Biopsies can be taken if required, enabling a precise diagnosis and tailored treatment plan. Horses must be fasted overnight before the procedure to ensure the stomach is empty for optimal imaging.

Gastric ulceration is common across all types of horses, although prevalence varies by breed, use, and training level. Thoroughbred racehorses are most commonly affected, but studies show 17–58% of showing and sport horses and up to 59% of pleasure horses may also develop ulcers. Symptoms can include colic, poor appetite, weight loss, poor coat condition, diarrhoea, behavioural changes, and reduced performance.

We provide a fully mobile video gastroscopy service, meaning examinations can be performed at your yard, as well as at our clinic. All of our vets are trained and experienced in performing gastroscopy, ensuring safe, accurate, and efficient procedures in any setting.

Our digital video gastroscopes capture high-quality images and allow image recording, which is invaluable for monitoring lesions over time and assessing response to treatment. Video gastroscopy enables complete examination of the oesophagus, squamous and glandular regions of the stomach, the pylorus, and the proximal duodenum. Repeat examinations can be performed to guide treatment and track healing.
