An endoscope is a flexible fiberoptic tube that is inserted into the area that needs to be examined. This can be the nose, trachea, bronchi, esophagus, stomach, small intestine, colon or urethra. The endoscope permits viewing of the inside of these organs, and allows for biopsies or other samples to be obtained as well as providing a means of retrieving foreign objects an animal may have eaten such as toys, rocks, coins, fabric or fishhooks.
