Accuracy of Real Time Characterization in Artificial Intelligence-assisted Colonoscopy

The goal of this substudy is to investigate the accuracy of a computer-aided polyp characterization (CADx) system. The main question\[s\] it aims to answer are: • How high is the specificity of the AI system when characterizing colorectal polyps Participants will receive a standard colonoscopy, assisted by the artificial intelligence (AI) assisted system GI Genius. Researchers will compare the AI system´s characterization with the histopathology to see how accurate the system is.

Inclusion Criteria: * Referred for screening colonoscopy due to a positive faecal immunochemical test (FIT) or for * Diagnostic colonoscopy due to symptoms/signs or * Post-polypectomy surveillance colonoscopy (only patients who had all detected polyps removed in the previous colonoscopy) Exclusion Criteria: * Referral for removal of previous detected polyps * Emergency colonoscopy * Control colonoscopy due to inflammatory bowel disease (IBD)
