About this trial

The endoscopic grading system (EGGIM) has been widely used to assess the extent of gastric intestinal metaplasia during endoscopy. Investigators developed an artificial intelligence (AI) system to automatically evaluate the extent of gastric intestinal metaplasia (GIM) and calculate the EGGIM scores in endoscopy examination. This study is a prospective, multi-center study aimed at exploring the performance and reliability of AI-EGGIM scoring.

This is a prospective study designed to validate the AI-EGGIM system in a larger cohort. The study protocol was developed based on preliminary experience from a prior investigation (NCT05464108).

Performance of AI system to diagnose the grade of intestinal metaplasia by calculating the EGGIM score

The performance of the AI system will be evaluated in diagnosing the grade of gastric intestinal metaplasia (IM) based on the Endoscopic Grading of Gastric Intestinal Metaplasia (EGGIM) system. EGGIM is a validated scoring method ranging from 0 to 10, reflecting the extent of IM across five gastric regions: two in the antrum, two in the corpus, and one at the incisura. Each region is scored as 0 (no IM), 1 (focal IM, ≤30% of the area), or 2 (extensive IM, \>30% of the area), with a total possible score of 10. Higher EGGIM scores correspond to more severe IM and greater gastric cancer risk. The AI-derived scores will be compared with expert' EGGIM scores, which serve as the gold standard, to assess diagnostic accuracy.
