Yes. My first band was taken out and a new one replaced n the same surgery. If scare tissue or any snags is present when they remove the first one, they possible cannot replace the second.
I went 1 1/2 years having severe reflux and not tolerating fills. I had multiple upper gi swallows/ egd. They said my band was ok. They finally went n and looked and found it slipped. Don't keep suffering if they don't find anything, Switch dr's. That is finally how my first slip was found. By the time I got someone to agree to do surgery on me to see if slipped, I got very anemic, dropped too much weight, and aspirated nightly on stomach content. I was miserable.. Felt awesome with 2nd band. No problems, no puking. Had sudden abdominal and chest pain.
