Abstract: Bariatric and metabolic surgery currently grapples with multifaceted challenges due to the global surge in obesity. The application of artificial intelligence (AI) technologies presents transformative potential to address these complex dilemmas. The authors review the application of AI in the perioperative period of bariatric and metabolic surgery, indicate the promising prospects of the integration of AI and bariatric and metabolic surgery. Meanwhile, in the process of its extensive application, pertinent ethical concerns should be duly considered. At present, the in-depth application ability of AI by doctors remains relatively low. In the future, the combination of AI with internet of things, robotic surgery, surgical education, and genomics will become the core direction of bariatric and metabolic surgery development.
