In recent years，with the rapid development of metabolic and bariatric surgery in China，more and more hospitals started to establish a metabolic and bariatric surgery team providing treatment to patients，and as a result，the annual number of operations has been increasing sharply. At the same time，it is increasingly important to continuously promote the standardization of clinical practice in this discipline in order to improve clinical quality and outcomes. At this stage，as the fundamental of standardization and continuous quality improvement，systematic training is crucial to the surgeons and case managers who are working in this area. In addition，surgeons need to strictly follow the surgical indications and choose an evidence-based operation to patients. After surgery，long-term follow-up and clinical data management are also important measures to promote the standardization of metabolic and bariatric surgery.
