Endoscopists must report the endoscopic activity and rely on the biopsy results to predict the histological activity.  \nMethods: We aimed to develop a deep learning-based algorithm to evaluate the disease and histological activities of UC based on white-light endoscopic images obtained during the procedure in this research. A deep learning system for classifying the colonoscopic images for assessing the endoscopic and histological activities of UC patients was developed. Its performance was evaluated with an independent dataset. The system was utilized to analyze the captured video segments, and the results were compared with those of human endoscopists.  \nResults: A total of 375 video segments from 82 patients were utilized to develop the endoscopic and histological activity prediction assurance algorithm. Among the 375 video segments, 60%, 20%, and 20% were used for training, validation, and testing the proposed vision transformer (ViT) model, respectively. Moreover, four senior and six young endoscopists reviewed and scored the endoscopic and histological activities based on 77 testing video clips. The accuracies were 77.92%, 71.00%, and 83.12% for histological healing; and 74.35%, 72.51%, and 92.21% for complete mucosal healing (Mayo Endoscopic Score 0 vs 1–3), among senior endoscopists, junior endoscopists, and the ViT model, respectively. Conclusions: Our novel deep learning-based model, based on endoscopic videos, was comparable to that of experienced endoscopists and surpassed that of young endoscopists in predicting histological remission and complete mucosal healing.  \nKeywords  \nColon, colonoscopy quality, deep learning, ulcerative colitis  \nReceived: 27 July 2025; accepted: 16 December 2025  \nIntroduction  \nInflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis (UC), is a chronic condition characterized by persistent intestinal inflammation that requires continuous treatment and surveillance to monitor disease activity, thereby improving patients’ quality of life and preventing complications.1 Although UC treatment has progressed from steroid, 5-aminosalicylic therapy to the recently introduced advanced therapy, the treatment goal has also evolved from clinical remission to endoscopic and even histologic remission.2 Artificial intelligence (AI)  \n1 Department of Computer Science and Information Engineering, National Taichung University of Science, Taichung, Taiwan  \n2Graduate Institute of Biomedical Electronics and Bioinformatics, National Taiwan University, Taipei, Taiwan  \n3Division of Gastroenterology, Changhua Christian Hospital, Changhua, Taiwan  \n4Artificial Intelligence Development Center, Changhua Christian Hospital, Changhua, Taiwan  \n5Department of Post-Baccalaureate Medicine, College of Medicine, National Chung Hsing University, Taichung, Taiwan  \nCorresponding author:  \nHsu-Heng Yen, Division of Gastroenterology, Changhua Christian Hospital, Changhua, 500, Taiwan.  \nEmail: 91646@cch.org.tw  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons Attribution  \nNonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/l","cbCainKtucDZPBxX","https://ap.wps.com/l/cbCainKtucDZPBxX","pdf",4863588,12,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# Keywords\n# Introduction","[{\"question\":\"What problem does the study address in ulcerative colitis?\",\"answer\":\"Accurate assessment of endoscopic and histologic activity in UC is critical, but traditional scoring systems suffer from subjectivity, interobserver variability, and limited granularity.\"},{\"question\":\"How was the AI model developed and evaluated?\",\"answer\":\"A total of 375 video segments from 82 patients were used, and performance was assessed using testing clips scored by four senior and six young endoscopists.\"},{\"question\":\"What were the main findings compared with human endoscopists?\",\"answer\":\"The vision transformer model was comparable to experienced endoscopists and surpassed young endoscopists in predicting histological remission and complete mucosal healing.\"}]","Comparison of the performance between an AI-based vision transformer and human endoscopists in predicting the endoscopic and histologic activities of ulcerative colitis | PDF",1790718838]
