Endoscopy is a minimally invasive diagnostic medical procedure that is used to assess the interior surfaces of an organ by inserting a tube into the body. It is an essential diagnostic tool for pets with disorders of the gastrointestinal tract. The endoscope instrument has a built-in camera at the end of either a rigid or flexible tube, allowing for both visual inspection and photography. Many endoscopes have a channel through which biopsy or retrieval forceps may be placed to perform many different procedures including foreign body removal from the esophagus and stomach. Ask your veterinarian if endoscopy may be right for your pet.
