While I think that long surgeries at UVA are particularly excruciating (especially to grumbling stomachs and full bladders), even if you had the option to leave, would you take it?
I am not that interested in surgery, but I would stay for the full operation because it shows enthusiasm and interest. I think the best way to get the most out of the long surgeries is to somehow make there be more teaching. Isn't it a requirement that the residents teach us?
As for lack of time to read, I agree, but honestly the info I remembered the best was stuff I was pimped on in the OR or on rounds.
