Surgery performed standing up?
same with me too, you don't slide off because they strap you on very well. The anesthesiologist explained it to me before time. I think it has to do with better angles, as all the organs aren't squishing eachother.

Mine was performed similarly. I don't think I was literally standing up, but the table was angled sharply with my feet toward the floor. They strapped me onto the table securely and then put a foot board at my feet to keep me from sliding out of the straps. I mean to ask the surgeon for the reason when I see him next.
