Re: Endoscopy (A little confused)
Endoscopy is a scope that goes into the esophagus, stomach and they can view a small portion of the small intestine...but they can not go through the small intestine, let alone the large intestine. The large intestine is done with colonoscopy, and the only way to vies the small intestine is with the Pillcam SB (small bowel).
Whenever you have reflux they want to check out your esophagus. If your pain is lower than you need to call your dr and find out what his/her reason is. You may need another test to address that issue. Some Dr's want to scope people as a way to make money....I know its wrong, but not everyone is on the up and up. I just did the pill cam ESO (for the esophagus) and it is truly a piece of cake..and really cool! The small bowel pillcam is the same, except they record the data for 10 hours or so.
Good luck, and dont let someone do something to you unless you really need it, have symptomology, etc.
