The goal of this clinical trial is to evaluate the diagnostic accuracy of the AI-integrated Capsule Gastroscopy (ACG) system in simulated home-use conditions for detecting upper gastrointestinal (UGI) abnormalities. It will also compare the diagnostic accuracy and time efficiency of AI-assisted interpretation versus manual reading of ACG data. The main questions it aims to answer are: What is the diagnostic accuracy of the ACG system, using conventional esophagogastroduodenoscopy (EGD) as a standard of reference? Does AI-assisted ACG reading improve diagnostic accuracy or reduce reading time compared to manual ACG video reading? Researchers will compare ACG results to conventional EGD findings (standard of reference) to determine if ACG can serve as a reliable method for UGI disease detection in home scenarios. Participants will: Undergo an ACG examination in a simulated home environment. Complete an EGD procedure within 24 hours post-ACG ingestion.
Conditions: Gastric Lesion, Gastritis, Upper Gastrointestinal Bleeding (UGIB), Gastric Dysplasia, Gastric Ulcer, Gastric Neoplasms
Eligibility Criteria
Inclusion Criteria
