Hi Sherry,The biopsies shouldn't be a problem at all...he shouldn't feel anything post EDG, and of course he'll be out cold when they take them. Like Bill, I thought of a stricture, which is probably the reason for "vomiting" which is likely coughing up food that doesn't make it through the narrowing. It's a fairly common problem with GERD. I wonder if they'll dilate it during the procedure. It would make sense!
Good luck!
Denise
