Artificial intelligence-assisted endoscopic diagnosis system for diagnosing Helicobacter pylori infection: a multicenter study
This multicenter diagnostic study developed and validated HOPE AI, an artificial intelligence system for detecting Helicobacter pylori infection using a multi-instance learning framework and transformer-LSTM architectures. Leveraging 308,887 endoscopic images and 197 videos from 6207 patients across seven hospitals, HOPE AI achieved superior diagnostic accuracy (AUC up to 0.932) and significantly higher sensitivity (85.7%) compared to senior endoscopists (68.0%). The system demonstrated robust performance and interpretability, enhancing diagnostic efficiency for H. pylori detection in routine screening, while acknowledging limitations related to data generalizability and potential biases.

Real-world Impact: Enhanced H. pylori Screening
A major challenge in H. pylori management is the lack of standardized, objective endoscopic parameters and heterogeneous diagnostic accuracy among clinicians. HOPE AI addresses this by providing a consistent, high-accuracy diagnostic tool.
Outcome Highlights:
Improved Diagnostic Efficiency: By automating image analysis and highlighting high-risk regions, HOPE AI reduces inter-observer variability and aids endoscopists in identifying H. pylori infections more reliably. This is crucial for routine screening contexts, enabling prompt diagnosis and eradication to mitigate gastric cancer risk.
- AUC (Internal Validation): 0.932
