Gastric endoscopy is commonly known as the use of a black tube with a camera to enter the esophagus from the mouth through the throat to observe the esophagus, stomach, and duodenum (bulb, descending) for There is no unusual process. In the same way, colonoscopy is the process of using a black tube with a camera to enter the large intestine from the anus to observe the mucosa of the large intestine.
