we use isop (not sure if thats how its spelled) for lap prostatectomies and think it is great as you dont lose a hand just for the scope. The room we use it in is renovated and set up in a very technologically friendly way its the room we do most lap cases so its not to much extra to do aside from bringing the machine in, changing the input to svideo and plugging the surgeon in.
and the surgeon can take over control anytime if isop isn't working.
Keep in mind though I am a new nurse in the OR and haven't seen much and am an extra while circulating so maby it is a bigger deal when there is no extra.
