I worry that you have to answer this question. If you are having an endoscopy, it should be done only by your bariatric surgeon, since most gastroenterologists have no experience in dealing with bands or diagnosing and treating the problems that band patients have. Why are you having an endoscopy? If it is for a problem such as reflux, heartburn, or difficulty swallowing, then it probably isn't necessary in the first place; a simple upper GI x-ray would answer the question. Gastroenterologists make money by doing scopes, so they do them whenever possible. The main reason to do an endoscopy on a band patient is to see if the band has eroded into the stomach. Talk to your surgeon before you get 'scoped.
