Endoscopy is a nonsurgical procedure used to examine a person’s digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, the doctor can view pictures of the patient’s digestive tract on a color TV monitor.
There are many different types of endoscope, and depending on the site in the body and the type of procedure, endoscopy may be performed by a doctor or a surgeon, and the patient may be fully conscious or anaesthetised. Most often the term endoscopy is used to refer to an examination of the upper part of the gastrointestinal tract.
