As a person w/Crohn's disease I've read of so many Crohn's disease and/or UC patients who have encountered a colonoscopy where for whatever reason they were not adequately sedated. Many not only endured a lot of pain but asked, pleaded and begged the doctor to stop and the doctors did not. I'm always aghast as that. I know reimbursement for an incomplete scope can be a real PITA but nonetheless is it really ethical for a doctor to continue when the patient has asked that he/she stop? I know the doctor and I would part company in a hurry plus I would file a complaint w/the hospital, the state licensing board and his state professional organization if I were to encounter such a situation.
