Hi, I had the Double Balloon Endoscopy done at the Mayo in Scottsdale, AZ, in 2006. At that time it was quite new there and they were able to go through the mouth farther than I had had an endoscopy go before, but still not as far as they had hoped. I was under general anethesia and was well taken care of. I went home later in the day, and then I had to reschedule the procedure for the rectal approach. I did that approach several months later, and again they were unable to go as far as they had hoped, so the entire digestive system had not been visualized as they thought they could.
I am willing to go through it again if they are able to see the entire length, at least into the area of the illium where my problems seem to be at their worst.
Dr. Leighton did the scope and he is well known for his work in this area.
I hope this helps you a bit, and good luck if you decide to go through with the DBE.
Anne
