Endoscopy?
I've had several. The first was pre-surgery when I was being checked for GERD (which I had). Then I had another one about 2 mos. after my surger when I developed a stricture. The surgeon went in and stretched the opening between my stomach and my intestines so more food could pass through. She did another one about 2 weeks later and I've had no problems since. They give you a kind of twilight sleep, but I don't remember anything at all. I did get kind of sick after the last one (from the anesthesia I think) and I had to stay there about 2 hours instead of 45 min. Hope this helps, Jen
