I think the differencece is how far they go, I think if they just check the duodenum and the very beginning of the jejunum, it taks only a few minutes and one does not need any sedation.

I will have another endoscopy in three weeks' time and this will be like that again. The doctor has an office in a builiding without anesthesia etc anyways.

I have also seen a colonoscopy, and the patient was wide awake and talking to the doctor. He went a bit up (actually some meters, because I saw how much of the tube was left, ther was not much left....) and one could see the intestines on the tv. (all was fine, and they took samples just to be sure. Snipped away some polyps. Patient had some olyps removed some time ago)....
