研究目的:

基于京都胃炎分类,对内窥镜下诊断为CAG的内镜特征进行识别,并与其病理活检结果进行比较,研究CAG患者内镜特征与病理的一致性,初步阐述二者不一致的原因,并评估人工智能使用内镜和病理图片预测CAG的诊断准确性,为提高检查者对该病的检出率提供帮助,同时探索一种病理与内镜联合的内镜医生学习模式  

Objectives of Study:

Ased on the Kyoto Classification of Gastritis, this study identifies the endoscopic features diagnosed as Chronic Atrophic Gastritis (CAG) and compares them with the corresponding histopathological biopsy results. The research aims to investigate the consistency between endoscopic features and pathological findings in CAG patients, initially elaborating on the reasons for their discrepancies. Additionally, the study evaluates the accuracy of artificial intelligence in predicting CAG diagnosis using endoscopic and pathological images, aiming to improve the detection rate of this condition among examiners. Furthermore, it explores a combined learning model for endoscopic physicians that integrates pathology with endoscopy.
