Abstract: With the innovation of obesity treatment concepts and surgical equipmentes, the procedures of metabolic and bariatric surgery have become more and more diversified. In addition to the widely used laparoscopic surgery, robot-assisted surgery, endoscopic therapy, and implantable weight loss devices have been constantly emerging and apply to clinical treatment, and achieved remarkable therapeutic effects. As a young branch of surgery, the ability to quickly absorb new technologies is a major feature of metabolic and bariatric surgery. Through the data support of various clinical studies with standardized, large sample sizes, and multiple centers, more effective, minimally invasive, and convenient treatment methods will surely evolve in the near future, which will meet the diverse needs of more obese patients while ensuring safety and weight loss effects. The authors review and look forward to the innovative surgical methods and techniques in metabolic and bariatric surgery, in order to provide reference and inspiration for the academic community.
