[Mission and vision of clinical research in bariatric and metabolic surgery].

Clinical research progress in bariatric and metabolism research had promoted the development in clinical practice. In U. S and Europe, pivotal scientific questions had been explored by clinical researchers, which brought the updating of guidelines, accumulation in key evidences, promotion of the consensus of metabolic benefits, following further development in scientific area. Compared to U. S and Europe, clinical practice in bariatric and metabolic surgery development in China started later. Clinical research in China just developed into initial phase with few achievements with high quality and breakthrough contribution. However, with wider practice, larger patient population and higher quality of surgery, clinical research in bariatric and metabolic surgery in China will go to a new stage through clinical research with standardized guidance, broad cooperation and clinical data digitalization and standardization.
