Strange Question
I have a few times, and now they are dainty little lady-like burps, rather than those magnificent huge belches pre-surgery, lol. Just not much room for air in there nowadays, but I am sure eventually you will burp again.
I wish I could burp on command, because sometimes it would help with the pouch, but unfortunately I never had that talent.

For the longest time after surgery I didn't burp, I would hiccup instead. Empty stomach, full stomach, didn't matter. Even when I tried to intentionally burp, I would hiccup. It got so annoying. But finally I am able to burp. Still not when I want to, but I can now.
That's an interesting question I'm sure your surgeon could answer if you ask
