Core Tip

Core Tip: Due to significantly lower incidence compared to colorectal polyps and macroscopic features resembling hyperplastic polyps, rectal neuroendocrine tumors (rNETs) are frequently misdiagnosed and resected as polyps. This often leads to the need of additional salvage treatments or repeated imaging and endoscopic follow-ups. To the best of our knowledge, there are currently no reports on the application of artificial intelligence for assisting in the white-light diagnosis of rNETs. In this study, we developed a model for the detection of rNETs based on the YOLOv7 algorithm, which demonstrated high diagnostic performance and outperformed the majority of endoscopists in lesion identification.
