Colon cancer screening behavior seems to be associated with having a regular primary physician, as well as other cancer screening behaviors. Knowledge of colon cancer is the most reliable discriminator of prior screening status. There does not seem to be any difference in the preferences expressed by never-screened and screened patients with respect to the aspects of colonoscopy that they find objectionable.

On the basis of lower rates of bleeding, EPBD should be the preferred strategy over EST for endoscopic removal of common bile duct stones in patients with coagulopathy. Although EPBD is theoretically attractive for use in young patients for biliary sphincter preservation, the rate of pancreatitis is higher with EPBD and cannot be routinely recommended at this time.
