Ten Years of Change in Bariatric/Metabolic Surgery in the Asia-Pacific Region with COVID-19 Pandemic: IFSO-APC National Reports 2021.

BACKGROUND: On November 25, 2021, the IFSO-Asia-Pacific Chapter (IFSO-APC) Virtual Meeting 2021 was held online, and the representatives from the Asia-Pacific region presented 10 years of change in bariatric/metabolic surgery and the influence of COVID-19 in the special session of "IFSO-APC National Reports 2010-2020". We herein report the summarized data. METHODS: National bariatric/metabolic surgery data, which included the data of 2010 and 2020, were collected from the representatives using a questionnaire that consisted of 10 general questions. At the congress, the data were calculated and summarized. RESULTS: Thirteen of the 14 national societies responded to the survey. From 2010 to recent years, the populations of individuals with obesity (BMI ≥ 30 kg/m2) and individuals with diabetes both significantly increased. Eight countries and regions expanded the lower limit of criteria for bariatric surgery by 2-5 kg/m2 (BMI), and 5 countries newly established criteria for metabolic surgery in the last ten years. Sixty-nine percent of the countries currently run public health insurance systems, which doubled from 2010. The number of bariatric surgeons and institutions increased more than threefold from 2010. In 2010, 2019, and 2020, surgeons in IFSO-APC societies performed 18,280, 66,010, and 49,553 bariatric/metabolic surgeries, respectively. Due to the COVID pandemic, restriction policies significantly reduced access to surgery in South and Southeast Asian countries. The biggest changes included increased numbers of bariatric surgeons and institutions, operation numbers, public insurance coverage, raising awareness, and national registry systems. CONCLUSION: For the last 10 years, bariatric/metabolic surgery has rapidly grown in the Asia-Pacific region.

Bariatric/Metabolic Surgery in the Asia-Pacific Region: APMBSS 2018 Survey.

INTRODUCTION: The Asia-Pacific Metabolic and Bariatric Surgery Society (APMBSS) held its congress in Tokyo at the end of March, 2018, and representatives from Asia-Pacific countries presented the current status of bariatric/metabolic surgery in the "National Reports" session. The data are summarized here to show the current status and problems in the Asia-Pacific region in 2017. METHODS: A questionnaire including data of 2016 and 2017 and consisting of eight general questions was prepared and sent to representatives in 18 Asia-Pacific countries by e-mail before the congress. After the congress, the data were analyzed and summarized. RESULTS: Seventeen of 18 countries responded to the survey. The frequency of obesity (BMI ≥ 30) in the 4 Gulf countries was > 30%, much higher than that in the other countries. In total, 1640 surgeons and 869 institutions were engaging in bariatric/metabolic surgery. In many East and Southeast Asian countries, the indication for bariatric surgery was BMI ≥ 35 or ≥ 37, whereas in many Gulf countries and Australia, it was BMI ≥ 40 or ≥ 35 with obesity-related disease. Ten of the 17 countries (58.8%) but only one of the 5 Southeast Asian countries (20.0%) had public health insurance coverage for bariatric surgery. In 2017, 95,125 patients underwent bariatric/metabolic surgery, with sleeve gastrectomy accounting for 68.0%, bypass surgery for 19.5%, and others for 12.5%. Current problems included public insurance coverage, training system, national registry, and lack of awareness and comprehension. CONCLUSION: This summary showed that bariatric/metabolic surgery is rapidly developing along with various problems in Asia-Pacific countries.
