RESUMO
In recent years, artificial intelligence technology has made a number of technical progress in almost all fields, including the medical field. At present, AI-assisted upper gastrointestinal endoscopy has been introduced into clinical practice as a clinical decision support tool.With the help of artificial intelligence and the expertise of endoscopy experts, artificial intelligence is expected to be an effective tool to improve the diagnostic ability of endoscopy,especially for endoscopy beginners and inexperienced endoscopists.The emergence of artificial intelligence is of great significance to improve the working efficiency and diagnostic ability of endoscopists. However, the application of artificial intelligence in upper gastrointestinal endoscopy is still in the exploratory stage and has not been widely applied in clinical practice.
