PATHOLOGY, COLORECTAL POLYP
Before and after the interactive training or self-driven training, all trainees were given a QR code with 20 selected cases of colorectal polyp under BLI for testing. To decrease investigator bias, the investigators who were in charge of the research design were forbidden to be the test scorers. For control measures, the test scorers were blinded to the randomization. The trainees reviewed these images and made a diagnosis by entering the judgement of the NICE classification, the color, the vessel pattern, the surface pattern, and confidence in diagnosis (low or high). All the images were retrieved during standard care without any interventions or exposure of the patient’ personal information. These images of polyps were obtained using high-definition colonoscopes (EC-L590ZW, EC-L590ZP, EC-760ZP-V/M; Fujifilm Co). The polyps in the collected images in the before-training tests and the after-training tests had been resected and evaluated by pathology for histology confirmation.
