Hi Mike,
Nope! never had to have it tightened, after you've had it done you will revist your consultant and they will give you an endoscopy, after about 3 months, my Barretts had basically dissappeared, I have them say every 2-3 years now, never get indegestion and most definitely ever get reflux, never! I can eat spicy food, I can eat toatoes, orange juice, acidic foods basically anything I could never eat before, and yes! I can drink Alchohol and fizzy drinks no problem at all, the only side effect I have noted is, is that my stomach does bloat up, lol, it does get full of gas, as now, it dosen't come out of my osephagus lol, so that is about the only downfall, but this does subside after a couple of hours, and only if I have been eating gassy food stuffs. I used to have horrendous GORD, intolerable, constant burning, so uncomfortable, not anymore.
Mike I can only go by my own experience, I believe there probably are some horror storys, but theres always going to be horror stories for any condition, that anyone has, as I said, you have two choices, not to have it, and be free of GORD live a normal, healthy life or keep taking Lansoprazle, which isn't a guarantee of getting rid of Barretts, it didin't with me, and if you decide (I don't know why to be honest) that a fundoplication is not for you, then simply have the operation reversed, it's not dificult to do.
Theres not much more I can tell you, but as you can tell after 20 years my operation is still a 100% success, I've never looked back, god knows what would have happened if I had never had this operation, the bloated tummy is a small price to play, and it dosen't last long, it does go down.
