Horse Endoscopy in Welfare Assessment

How equine endoscopy is used as a welfare assessment and diagnostic tool beyond clinical use in upper airway and gastric evaluation.

Key Facts

Equine gastroscopy allows direct visualisation of squamous and glandular stomach mucosa - the gold standard for EGUS diagnosis
Upper airway endoscopy at rest and exercise identifies structural causes of reduced performance and potential respiratory welfare compromise
Tracheal endoscopy with bronchoalveolar lavage is the definitive test for equine asthma and lower airway disease
Endoscopic examination under sedation is well tolerated by most horses with appropriate handling and chemical restraint
Welfare assessment using endoscopy goes beyond diagnosis to include monitoring treatment response and confirming resolution
Routine diagnostic endoscopy is underused in equine practice relative to the information it provides about welfare-relevant conditions

Welfare Considerations

Equine endoscopy represents a welfare-improving diagnostic investment that is often deferred due to cost or perceived invasiveness. A horse with undiagnosed gastric ulcers will continue performing in pain; one with undiagnosed lower airway disease will continue to experience respiratory compromise during exercise. Endoscopy converts these silent welfare costs into manageable medical conditions by making the invisible visible. The welfare case for endoscopic investigation of performance problems, poor condition and behavioural changes is compelling - it enables targeted treatment rather than empirical medication, and confirms resolution rather than assuming it.

What You Can Do

Ask your vet about gastroscopy for any horse showing girth sensitivity, poor performance or behaviour changes under saddle
Request upper airway endoscopy for horses with abnormal respiratory noise or exercise intolerance before escalating training pressure
Consider tracheal endoscopy and BAL for horses with a chronic cough or reduced performance without clear lameness cause
Do not defer endoscopy purely on cost grounds when welfare-relevant conditions are clinically suspected
Ensure post-treatment gastroscopy to confirm ulcer healing rather than assuming resolution based on clinical improvement alone
Work with your vet to develop a monitoring protocol that includes repeat endoscopy at appropriate intervals for horses with chronic conditions
