Summary
Brief summary (as posted)
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.

Arms (1)
- label
- Routine colonoscopy Cohort
- description
- Patients receiving routine colonoscopy at the study site
Primary outcomes (1)
- measure
- Adenoma detection rate in the proximal colon
- timeFrame
- up to 2 weeks (participants will be followed for the duration of hospital stay or outpatient treatment, an expected average of 2 weeks)
- description
- 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.
