@johnhenry, I see that you have recently joined Mayo Connect and I want to extend my hand to you in a virtual handshake of welcome. We are happy to have you join us in this discussion group, and we invite you to look at and/or post in any of the groups that might be related to the reason for your inquiry.
I am not sure who you were addressing this to. If you want to address your question to a particular individual, just copy and paste their @name and they will be able to reply.
My own experience has always been that Mayo Clinic will work with you, the patient, to provide for your needs in the most efficient manner possible. While I don't have any experience directly related to your surgery question, I can share that once my doctor in the transplant department did stay late to see me so that I could be on my way home before an incoming snow storm.

Are you scheduled for an appointment to Mayo? Are you anticipating the need for surgery?
Rosemary
