Real-time artificial intelligence improved the gastric lesion detection rate in endoscopy
- What
- The researchers evaluated the effects of introducing a real-time artificial intelligence (AI) detection system for low-definition endoscopy exams performed in resource-limited settings.
- Key result
- After the introduction of artificial intelligence, the overall lesion detection rate per patient increased slightly, the detection rate of small lesions of 0.5 cm or less also increased, and the biopsy rate decreased.
- Why it matters
- This technology can be utilized to help detect small gastric lesions and reduce unnecessary biopsies without compromising cancer detection, even in resource-limited settings.
Background
Detecting early gastric cancer and small lesions under 1 cm using gastrointestinal endoscopy remains a difficult challenge. This study aimed to evaluate the impact of introducing a real-time artificial intelligence (AI) detection system into low-definition endoscopy platforms commonly used in resource-limited settings.
Method
Diagnostic upper gastrointestinal endoscopy exams performed between September 2024 and May 2025 were analyzed. Lesion detection rates were compared between the periods before and after the introduction of artificial intelligence, and subgroup analyses according to lesion size and type were also conducted.
Main results
A total of 2,329 patients were included, and the overall lesion detection rate per patient increased after the introduction of artificial intelligence. While the detection rate for small lesions of 0.5 cm or less increased, the detection rate for larger lesions was maintained, and the biopsy rate decreased.
Limitations & open points
Since this is an exploratory before-and-after study conducted at a single center, additional validation in various settings may be necessary.

- Upper GI endoscopy — An examination where an endoscope is inserted through the mouth to observe the esophagus, stomach, and duodenum.
- Biopsy — An examination where a portion of suspected tissue is removed from a patient's body and observed under a microscope to diagnose a disease.
