I am 11 years out from rny gastric bypass and am sitting here waiting for my gastroenterologist's office to call so that I can schedule my second endoscopic dilation to fix a stricture that was diagnosed a couple of months ago. No ulceration. Just a narrowing of the gastrojejunal anastomosis with some inflammation. This is the first serious issue that I have had that has resulted from my surgery. Moral of the story, you can develop a stricture at any point post surgery, even 11 years out.
