Abstract
Morbid obesity and obesity-related comorbidities are major public health problems around the world, including in East Asia. Although Asian populations have been shown to have an elevated risk of type 2 diabetes mellitus, hypertension, and hyperlipidemia at a relatively lower BMI than Western populations, the Asian perspective on bariatric and metabolic surgeries has not been actively discussed until recently. Bariatric surgery in East Asia has undergone a paradigm shift since the first laparoscopic vertical bariatric surgery was performed in Taiwan in 1998, which was subsequently followed by the introduction of laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, and mini-gastric bypass. Since 2006, use of laparoscopic sleeve gastrectomy has remarkably increased because of its ease, speed, and safety. With regard to metabolic surgery, a randomized controlled trial in Taiwan demonstrated that laparoscopic Roux-en-Y gastric bypass is more effective than laparoscopic sleeve gastrectomy for surgical treatment of poorly controlled type 2 diabetes mellitus and metabolic syndrome. In this article, we describe the history of bariatric procedures, revision surgeries, weight-loss effect, and metabolic surgeries in Asian populations, and we also discuss minimally invasive bariatric surgery with some important citations.
