About this study

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).

Read the detailed description

Gastric intestinal metaplasia (GIM) is an important precancerous stage in the gastric carcinogenesis cascade. The endoscopic grading system (EGGIM) has been proposed as a practical method to evaluate the extent of GIM during endoscopy. Investigators developed an artificial intelligence (AI) system to automatically assess the extent of GIM and calculate EGGIM scores from endoscopic examinations. This study is a prospective, multi-center study aimed at evaluating the accuracy, performance, and reliability of AI-assisted EGGIM scoring.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • The diagnostic performance of AI system and endoscopistsDiagnostic test

    Eligible patients will undergo independent EGGIM score assessment by both endoscopists and the AI system.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Intestinal Metaplasia of Gastric Mucosa and Artificial Intelligence, run by Qilu Hospital of Shandong University at 3 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 2 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Performance of AI system to diagnose the grade of intestinal metaplasia by calculating the EGGIM score (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2025.
