Suspected upper gastrointestinal subepithelial lesion
Gastroenterology |
Malignancy
NO
To acquire training data to develop an AI to differentiate subepithelial lesions on ultrasound endoscopic images prospectively at multiple institutions, and to research and develop the AI at the University to investigate its efficacy
Efficacy
Accuracy in the three categories of SEL differentiation (GIST, leiomyoma, other SELs) on EUS videos in the AI diagnostic system and expert endoscopists
Diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, accuracy) of the AI diagnostic system and expert endoscopists in the two SEL categories (GIST, others)
Diagnostic performance in multi-category classification (accuracy, sensitivity per category)
Diagnostic performance of non-expert endoscopists, diagnostic performance of various tissue biopsies, and EUS findings that contribute to diagnosis
Observational
18 | years-old | <= |
Not applicable |
Male and Female
(1) Patients undergoing upper gastrointestinal EUS examination for the purpose of detailed examination, tissue sampling, and follow-up for suspected SEL lesions
(2) Age at the time of consent acquisition is 18 years or older.
(3) Patients who have given their voluntary written consent after receiving sufficient explanation about participating in this study, and with sufficient understanding.

Multicenter prospective cohort study
Target number of cases: Once the study data has reached the target number of cases and two years have elapsed since the start date of data collection, the study will move on to the collection of validation data. The validation data collection period will be 6 months. If the target number of cases is not reached, the enrollment period will be postponed.
1. Study data: 540 cases
2. Validation data: 180 cases
Evaluate the accuracy in the three categories of SEL differentiation (GIST, leiomyoma, and other SELs) on EUS videos in the AI diagnostic system and expert endoscopists.
