The 'end' examined: In upper endoscopy, the upper GI tract is examined, including the esophagus and stomach. In colonoscopy, a different scope is used, entering the anus, and progressing up past the rectum into the colon (the large intestine).

Colonoscopy vs.EGD: Technically, a colonoscopy is a form of "endoscopy" but typically, endoscopy is used to refer to upper endoscopy or egd. Egd is to look at the esophagus, stomach and duodenum, while colonoscopy is for the large intestine.
