No bowel prep before lap?

Getting my lap next week and my surgeon said bowel prep isn’t necessary, even though I mentioned that I’ve been having bowel issues- mainly constipation. Just wondering what the norm is with this!

Addition: my surgeon doesn’t think it’s invading my bowel because she said bowel endo usually shows up on MRIs. I did tell her I still suspect some sort of adhesions though. Would that require bowel prep or only if it’s deeply infiltrating the bowel?!
