Endoscopy is a minimally invasive technique that allows us to use an endoscope to directly visualize your pet’s organs and body parts through the natural openings of the body. This can allow us to give a more accurate diagnosis and institute treatment for oral, nasal, esophageal, stomach, colon, and even upper intestinal tract diseases. Some foreign objects can be removed this way without surgery and biopsies can be taken to aid in diagnosis.
