Hmm, as I'm not there yet myself I'm not sure I can help, but if none of the following have been covered in prior appointments, you could ask:
Is there anything you can do to help prepare yourself for the op (like buying Hibiscrub to prevent wound infection)?
How to care for your wound/wounds post-op...who takes the stitches out & when etc?
How long are you expected to be in?
How long do you need off work? Do you need to refrain from any activities to allow time for healing (like lifting heavy things)?
Pre-op/liver shrinking diet...what to eat & for how long..diet sheet etc?
Vitamin/minerals supplements? What medications do you need to take...what are they for & for how long? Does the hospital give them to you or do you need to get them from your doc when you get home?
Post-op diet...liquids/pureed foods for how long? When can you start introducing solids?
What happens if you feel ill/pain post-op...when to call them or see your doc?
Follow up appointments with them or your doc?
GIVE ME A DATE!!!!!
Hope you may find some of these suggestions helpful, hope you get a date soon & good luck! xxx
