Accuracy of Computer-aided (CADx) System in Real-time Characterization of Colorectal Ulcerative Diseases

The goal of this observational study is to test the diagnostic accuracy of the newly developed CADx system in predicting the histopathology of colorectal ulcers when compared to expert endoscopists. The main question it aims to answer are to demonstrate whether the newly developed CADx system has a high-level diagnostic accuracy in predicting characterization of colorectal ulcerative diseases. It is a multi-center study with two phases. The first retrospective phase is the development and validation of a CADx system by feature extraction from endoscopic photos and videos. The second prospective phase is the evaluation and comparison of the diagnostic accuracy between the CADx system, expert endoscopists and junior endoscopists.
