Endoscopy is a non-surgical procedure used to examine a person’s gastrointestinal tract or digestive tract problems. It is also known as an esophagogastroduodenoscopy.
Endoscopy is a procedure in which a long, thin tube with light and camera attached to it, is directly inserted into the body to observe an internal organ or tissue in detail.
Types of GI (gastroenterology) endoscopies performed:
- Upper GI endoscopy (esophagogastroduodenoscopy)– It is a procedure used to visually examine the upper digestive system and esophagus with a tiny camera on the end of a long, flexible tube. During this procedure, an endoscope is easily passed through the mouth and throat into the esophagus, stomach, and upper part of the small intestine (duodenum).
- Sigmoidoscopy or colonoscopy– During this procedure, an endoscope is passed into the large intestine (colon) through the rectum to examine the area of the rectum and the lower part of the large intestine, known as the sigmoid colon.
- Enteroscopy– This procedure is used to examine the small intestine by entering an endoscope through the mouth or anus.
