These devices cannot be sterilized, and do conduct electricity. The infection rate and the burn risk are both unacceptably high, and I doubt you would find a board certified plastic surgeon willing to participate in an experiment that has already been done and has failed. Best wishes.
All body piercings need to be removed before any surgery. They are a source of infection and could conduct electricity used during the procedure and cause a burn. It is a common misbelief than piercing holes will close up immediately when the piercings are removed. This is not true, they do not close up. You will be able to reinsert your piercings easily once the surgery is over.
