Comfort and efficacy of a longer and thinner endoscope for average risk colon cancer screening.

The aim of this prospective study was to assess patient comfort during nonsedated screening sigmoidoscopy with the use of a standard 60-cm sigmoidoscope compared with a thinner 100-cm upper endoscope. Patients undergoing routine colon cancer screening with sigmoidoscopy were randomly assigned to either a 60-cm sigmoidoscope or a 100-cm upper endoscope. The procedure time, depth of insertion, anatomic landmarks, and presence of polyps were documented.
