Here in Long Island, NY where I practice, it seems to be the norm to have a precolonoscopy visit. This visit serves several important purposes in my mind: I can meet the patient, take a history, and make sure they actually need a screening colonoscopy. I can answer all of the above questions in more detail than the primary doctor can. I also get to give them my basic talk about the purpose of a colonoscopy, how and why we remove polyps, the importance of good bowel prep and how to do it, and the small associated risks of a colonoscopy. We can talk about what to do with medications, and where to arrive on the day of the test, and parking, and all those seemingly small details that can make a patient stressed-out about the test for no good reason.
