Wishing the best of luck for Larry on this surgery and hoping it all goes picture perfect. My wife had the exact same surgery done 2-3 years ago for the very same reason.
I won't sugar coat it for ya though and just say that she had and still has some problems from having that surgery which so far, meds almost totally alleviate. It definitely took care of the problem she was having with the reflux, which meds weren't helping, but in turn caused her different troubles.
I hope your surgery goes textbook with everything as it used to be from now on for ya!
