An endoscope is a small flexible camera that we can use to visualise internal problems within the horse, typically in the respiratory tract but also involving the digestive or urogenital tracts.

Samples and washes can be collected from the trachea and lungs via the endoscope and assessed by pathology to identify infectious, inflammatory and neoplastic conditions.

Endoscopy is also an extremely useful tool in investigating poor performance issues or abnormal noises arising from the upper respiratory tract encountered at exercise.
