Endoscopy involves the use of a flexible fiber-optic scope that is passed through the mouth to evaluate the esophagus, stomach, small intestines and colon. This procedures is a minimally invasive diagnostic to retrieve biopsies from the intestinal tract. It can also help diagnose many gastrointestinal diseases such as irritable bowl disease and food allergies.
Endoscopy is also used to retrieve foreign objects from your pet with out the need for exploratory surgery.
Rhinoscopy involves scoping of the nose and nasal sinuses in dogs and cats. This is another minimally invasive diagnostic tool to investigate nasal diseases which leads to sneezing, discharge or nose bleeds. It also helps to diagnose any foreign bodies that maybe lodged in the nasal area, fungal disease and inflammatory disease of the nose.
Both the above procedures would be a drop off situation in the morning. Your pet would be put under anesthesia for a short period of time to perform the scope. Usually your pet would go home in the afternoon.
