METHODS: Through data reporting mechanism of the Shanghai Quality Control Center of General Surgery,the bariatric & metabolic surgery data were regularly collected and summarized. RESULTS: The number of hospitals developed from 11 in 2012 to 14 in 2018,and the overall surgery cases showed a progressive growth. In 2017, nineteen hospitals and 798 surgical cases had reached the highest level while decreased in 2018. The study showed that mean surgical time decreased to 112±14.8 min with no severe complication. The proportion of patients with type 2 diabetes pre-surgery decreased from 53.4% in 2014 to 30.9%in 2018. The proportion of sleeve gastrectomy(SG) increased from 68.4% in 2014 to 94.1% in 2018, which had become the most commonly bariatric surgical procedure. CONCLUSION: The amount of Shanghai metabolic and bariatric surgery increases year by year from 2012 to 2018, while increased little in 2017-2018,patients tend to be younger,mainly with obesity.
