Over the last years a number of new endoscopic imaging modalities have been introduced (high-definition and virtual chromoendoscopy). Given the theoretical advantage of these new imaging techniques, the investigators aimed to investigate their use for the detection of polyps during colonoscopy.

| Adenoma detection rate (ADR) | Percentage of colonoscopies with detection of 1 or more adenomas. ADR is a well-established quality indicator in colonoscopy in the prevalence of adenomas detected (ADR) as recommended by American Society for Gastrointestinal Endoscopy (ASGE)/American College of Gastroenterology Task Force (ACGTF) and European Society of Gastrointestinal Endoscopy (ESGE). Guidelines stipulate to use ADR as main quality indicator in colonoscopy. | 7-10 days |
| Measure | Description | Time Frame |
|---|---|---|
| Number of adenomas | Adenoma per colonoscopy rate (APCR) | 7-10 days |
| Type of adenomas | Subtypes of adenomas: tubular adenomas, tubulovillous adenomas, sessile serrated adenomas and adenocarcinomas |
