Thank you for your comments. I am with the Cleveland Clinic . There seems to be a routine to their scheduling process so it's fairly standard care for each person, so it seems I see whoever is on the rotation. As this may be my last procedure, due to being 77, I'd like to know what is going on in areas that have never been screened. And if I'm willing to do extra prep, etc. it seems reasonable to see a specialist who will meet me halfway. and accommodate my condition. It is taking a lot more research on my part up front. As I've become more knowledgeable about advanced techniques, I'm researching who at the clinic may be more skilled in them. As it turns out the clinic offers an advanced technique fellowship to other GI docs. And I plan to be an empowered self advocate and ask to see/consult with one of the faculty ,who was fellowship trained in advanced colonoscopy, prior to the procedure. Just curioius-did you have it at Stanford? Thank you for your response!
