Adenoma detection rate (ADR) is the most important parameter to measure outcome quality of (screening) colonoscopy. Since single improvements of imaging have not been able to improve ADR in many randomized studies, the present study tested the hypothesis that only multiple imaging improvements such as seen with two generation changes of colonoscopies - i.e. skipping one colonoscope generation - may be necessary before improvements in ADR can be measured. The investigators will test this hypothesis in the present randomized tandem study in 7 private practices in Hamburg and Berlin, in a pure screening colonoscopy setting, aiming at inclusion of 1200 patients \> age of 55 years (screening colonoscopy cut-off in Germany). Exclusion criteria are symptomatic patients and colonoscopies planned for therapeutic reasons. Main outcome parameter is the ADR (rate of patients with at least one adenoma/all patients).
