Effective colonoscopy requires a high rate of excellent and good bowel preparations, which can be achieved by split dose or same day dosing. Cecal intubation rates in screening patients should exceed 95%, and experts frequently achieve 99% or more. Cecal intubation should be documented by photographs of the appendiceal orifice and ileocecal valve and notation of landmark visualization. Withdrawal technique must include meticulous inspection of the proximal sides of the folds, clean-up of residual fluid and feces, adequate lumi-nal distension, and adequate withdrawal time. The endoscop-ist must be familiar with the full spectrum of endoscopic lesions, including flat and depressed lesions and serrated lesions. Optimal screening colonoscopy includes documentation of high quality by adequate adenoma detection rates, cecal intubation rates, and use of appropriate surveillance intervals.
