STRICTURE
I have a friend from another board who had WLS a few days before me and she's had to have the EGD done at least twice. I had one on 8/30 and thankfully, I've not any other problems. The surgeon told my DH that it was small, but not very bad at all.
To help the dialation work, you have to be sure to eat as often as your doctor says. If not, then it will start to shrink again.
Good Luck!
