Background and aims: No single endoscopic feature can reliably predict the pathological nature of Colorectal Tumors (CRTs). We aimed to establish and validate a simple online calculator to predict the pathological nature of CRTs based on white light endoscopy.
Methods: This is a single center study. During identification stage, 530 consecutive patients with CRTs were enrolled from January 2015 to December 2021 as the derivation group. Logistic regression analysis was performed. A novel online calculator to predict the pathological nature of CRTs based on white light image was established and verified internally. During validation stage, two series of 110 images obtained using white light endoscopy were distributed to 10 endoscopists (five Highly Experienced Endoscopists (HEEs) and five Less Experienced Endoscopists (LEEs) for external valida..
