I have only ever known GI's to do colonoscopy's. The colorectal surgeons at the hospital where Matt was didn't do the colonoscopy's, they strictly did the cutting.
My personal opinion is, surgeons are great at what they do but when it comes to diagnosing and your ongoing care of Crohns they really are not up on current treatments. If you can find a GI that is Crohns specialist or at least has an interest in it then you are far better of with them doing your colonoscopy.
I guess the exception to this would be if your surgeon strictly did surgery for IBD. I would imagine these type of surgeons would be few and far between and lets face it, the demographic and their bowels that most docs (paeds aside), whether they be GI's or surgeons, are seeing are not the age that majority of members on this forum are. I bet that when many people here are admitted to a specialist colorectal ward they would easily find themselves to be the youngest patient there. Hmmm, this last paragraph is most likely a lot of useless waffle to you! Sorry!
