for most difficult, i'd have to say transplant surgeon not in private practice. they work insane hours and have to go in the middle of the night to do organ harvests, etc. sometimes for least difficult i'd have to say a colorectal surgeon in private practice. i heard hours and overall lifestyle for colorectal surgeons (esp. those in private practice) are not that bad. but doing "butt surgery" FTL lol how about you, what do u think is the most difficult and least difficult surgical specialties regarding lifestyle?
