Endoscopy is a diagnostic procedure that allows the veterinarian to visualize and biopsy (obtaining samples of tissue for testing) places in your pet body that would otherwise only be reached by surgery. The tool is a long, thin instrument that works by using fibreoptics to visualize objects at its smallest end by looking into the eyepiece at the opposite end. We have most commonly used this for retrieving objects such in the nasal passages or examining/biopsying the digestive tract.
