Adenoma detection in the main goal of screening colonoscopy. In order to detect adenomas it is mandatory to spend a long enough time investigating the colonic mucosa. A minimum observation time of 6 minutes has been proposed as a quality criterion for screening colonoscopy. However, different locations of the colon (proximal, distal) may require specific observation time periods. The colon can be divided into a proximal (right) and distal (left) part. Until now, it is unclear whether observation time has a significant impact on adenoma detection in both parts of the colon. The aim of this study therefore is to conduct a trial in which side-specific observation times and adenoma detection rates are measured in order to investigate this correlation in particular for the right colon.

Adenoma detection rate in the proximal colon
After obtaining the histopathological diagnosis of resected polyps (approximately 3 -6 days) it can be determined whether the resected polyp contained adenomatous histology or not.
Time frame: up to 2 weeks (participants will be followed for the duration of hospital stay or outpatient treatment, an expected average of 2 weeks)
Polyp detection rate
a maximum of one day is expected for colonoscopy procedures
Time frame: up to one day
