Worked great for me for the last 25-30 years. The surgeon who did mine advised to make sure that your surgeon is experienced as some make it so tight that you can't belch or hurl/vomit. I can pretty much eat any of the foods that they advise to avoid. My one issue was that before the procedure I was given the antibiotic Ceftin to kill off any cold symptoms. It also killed off a lot of intestinal flora that made it hard to keep anything in. A coworker/friend recommended PLAIN yogurt which had me back to normal in jig time.
