An endoscopy involves examining the inside of a animal’s body using an endoscope. An endoscope is a medical device consisting of a long, thin, flexible tube which has a light and a video camera. Images of the inside of the patient’s body can be seen on a screen. Endoscopy is a minimally invasive diagnostic medical procedure. It is used to examine the interior surfaces of an organ or tissue.
Endoscopy can be used to examine the airways, and also the esophagus and stomach.
Sometimes x-rays cannot show all the details we require to make a diagnosis. Ultrasounds, using ultrasonic waves can help to show details of organs in the abdomen and heart. It is also used for pregnancy diagnosis.
