In most cases these examinations can be performed in the standing animal under restraint and the mobile crush facilitates these investigations on property. Samples from these sites can be collected via the endoscope channel (biopsy/lavage) and sent to the laboratory for further analysis.
The primary use of endoscopy in horses is to identify and assess upper respiratory issues and the indicators for investigation include:
Some respiratory conditions are able to be diagnosed based on visual assessment such as “roarers”, epiglottic entrapments, arytenoid chondritis and pharyngitis. Other respiratory conditions such as EPIH, inflammatory airway disease (IAD) and pulmonary abscessation require lavage samples to be collected and this can be done under endoscopic guidance. A few respiratory conditions are only evident at exercise and require Dynamic Respiratory Endoscopy (whereby the horse is “scoped” whilst working at speed) to achieve the correct diagnosis.
