NO
At our institution, we have developed EndoBRAIN-EYE (EB-EYE), a computer-aided detection system, and demonstrated its effectiveness. However, the utility of EB-EYE in detecting depressed-type tumors and laterally spreading colorectal tumors has not yet been evaluated. This study aims to examine the detection performance of EB-EYE for these types of lesions. Previously, EB-EYE output was displayed on a dual monitor system (with detection assistance shown on a separate screen from the endoscopic view), but it is now integrated into a single monitor system (with detection assistance displayed directly on the endoscopic screen). A retrospective comparison of adenoma detection rate (ADR) between the two systems will be conducted.
Efficacy
Based on endoscopic data from patients who underwent colonoscopy at our institution between January 1, 2020, and December 31, 2023, we will compare the adenoma detection rate (ADR) between single monitor and dual monitor systems. Additionally, we will assess the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of EB-EYE in detecting depressed-type and laterally spreading tumors. Patient characteristics (age, sex, date of examination), lesion characteristics (tumor size, gross type, location, pathological diagnosis), and the adenoma detection rate (ADR) with and without the use of EB-EYE during this period will also be evaluated.
