Abstract: The clinical decision in bariatric and metabolic surgery is influenced by several factors. Both patients and medical providers face conflicts when deciding whether to proceed with the surgery and which procedure to choose. Some clinical decision-making studies have provided high-level evidence to assist in selecting patients and surgical methods. Additionally, there are clinical decision support systems tailored to the needs of this specialty. However, there is currently a lack of a high-level clinical decision system for bariatric and metabolic surgery in China. The authors refer to previous research progress and conduct in-depth discussions on the clinical decision-making of bariatric and metabolic surgery based on patient selection and surgical method selection.
