Endoscopy is a diagnostic procedure that allows veterinarians to visualize and biopsy (obtaining samples of tissue for testing) the insides of your pet’s stomach, duodenum and colon without the need for invasive surgery. In some instances it can also allow retrieval of an accidentally swallowed item without the need for surgery. This technique is also commonly used in the upper airways (bronchoscopy). If we feel that endoscopy is an appropriate procedure for your pet, we can refer you to a facility that provides this service.
