I think I'd double check that. This is major surgery. Its doubtfull that it can be done with an Epidural even because its too high up, but then I may be wrong.
I've only ever heard of it being done open or with a Laporoscopy. Having said that when I had my post op Heamatoma removed, that was done on the bed with a local, and they did open the whole wound from breast bone to belly button so it is feasable I suppose.
Anyway I'm sure that which ever way you are having it done that you will be fine. Good luck with the op and welcome to Mini's.
