An endoscopy involves examining the inside an animal’s body using an endoscope. An endoscope is a medical device consisting of a long, thin, flexible (or rigid) tube which has a light and a video camera. Images of the inside of the patient's body can be seen on a screen. The whole endoscopy is recorded so that doctors can check it again. Endoscopy is a minimally invasive diagnostic medical procedure. It is used to examine the interior surfaces of an organ or tissue. It can also be used for enabling biopsies and retrieving foreign objects.
Endoscopy is a noninvasive alternative to surgery for foreign object removal from the gastrointestinal tract.
