Abstract

Background and aims: Advances in colonoscopy, such as the Pentax i-Scan electronic technique, have the potential to improve the early detection of colorectal cancer. The aim of this multicentre study was to assess the interobserver agreement in the visualization of the surface and margins of colorectal polyps and in distinguishing neoplastic from non-neoplastic polyps. Patients and methods: Eight expert endoscopists examined 400 mixed previously recorded images of polyps taken with different Pentax i-Scan settings in order to give an evaluation of the surface of the polyp and regular colonic mucosa, the pit-pattern and the nature of the lesion. Results: A total of 400 mixed images of polyps with a diameter >5mm and f agreement of 0.370 (pf agreement for the difference between neoplastic and non-neoplastic lesions was of 0.446 (p
