I've heard of this but I don't know much about it. My view is that it's pretty unethical...what right do the doctors have to change a couple's baby? They'd love it the way it is if they're good parents. The kid shouldn't need to change.
As for the parents getting it done for the baby, I think it depends on the importance of the surgery. Like if it's life threatening, then yeah, both parents and doctors should act on it. But to never tell to kid it happened...well...its not going to be the easiest thing to explain. But personally I feel it's not something you can keep from someone. I'm not sure of the consequences myself, but it sounds like a confusing and distressing ordeal to find that out thirty years later.
