It might depend on the surgery. I have had two surgeries in the last two years, and both were aided by robots. It is not done by the robot, but is considered to be 'aided' by one. The doc does the surgery. The incisions are much smaller, but there are multiple ones instead of one long one. Also, the docs say there is less chance for infection to be aided by a machine, and also to be released quickly. I was released the same day and didn't have any problems. Hospitals are full of bacteria, no matter how good the cleaning staff is, and I would rather be at home in familiar surroundings anyway. One surgery was gall bladder, the other was more intensive with a 6 week recovery period. I go in 2 more days to get the final all clear on the last surgery. So, yes, I think the quick send home is a good thing.
