Endoscopy: What You Should Know
What is an endoscopy?
Endoscopy uses a slim, flexible, lighted tube with a small video camera on the end. The camera is connected to a video screen, which allows a doctor to clearly see the lining of the digestive organs.
How an endoscopy is performed
In an upper endoscopy, a tube is passed down through the mouth to show the esophagus, stomach, and first part of the small bowel.
In a lower endoscopy (also known as a colonoscopy), a long, flexible tube is inserted through the anus up into the colon. The scope allows the doctor to see the lining of the entire rectum and colon.
Possible risks of an endoscopy
Mild sedation is needed when having an endoscopy, which always carries some risk.
