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 polypsParticipants 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 forDiagnostic colonoscopy due to symptoms/signs orPost-polypectomy surveillance colonoscopy (only patients who had all detected polyps removed in the previous colonoscopy)Exclusion Criteria:Referral for removal of previous detected polypsEmergency colonoscopyControl colonoscopy due to inflammatory bowel disease (IBD)
