Depends on what the surgery is.
If you're doing a standard surgery on an organ, for example an appendectomy, you just start by taking images of the organs, then if everything is where it normally is, they just use landmarks like slightly left of the bellybutton.
If you're doing surgery on some broken bones, you might have to make more measurements to ensure things are put back where they should be.
A lot of times, for really important surgeries, they'll make a full 3d model and have a template created that you place over the surgical area to ensure you get everything exactly where it should go.
