【摘要】 目的 统计分析中国多地区2021年度减重与代谢手术开展情况。方法 基于大中华减重与代谢手术数据库数据登记工作，统计分析2021年度各地区开展减重与代谢手术情况，并对病人人口学信息、肥胖相关疾病、手术信息等进行统计学描述和分析。结果 2021年度来自21个省（自治区、直辖市）共53家中心上传临床数据至大中华减重与代谢手术数据库，登记有效病例6807例。术前体重指数（BMI）为36.8 (21.0,87.5)。女性病人5102例（75.1%），年龄中位数为32(9, 72)岁；男性病人1689例（24.9%），年龄中位数为33(11, 65)岁。胃袖状切除术（SG）占84.9%,Roux-en-Y胃旁路术（RYGB）占3.1%，胃袖状切除联合空肠空肠旁路术（SG-JJB）占4.2%、单吻合口胃旁路术（OAGB）占3.5%、胃袖状切除联合双通道术（SG-TB）占1.7%、胃袖状切除联合袢式十二指肠空肠旁路术（SG-LDJB）占0.4%、胃袖状切除联合单吻合口十二指肠回肠旁路术（SADI-S）占0.3%、胆胰分流并十二指肠转位术（BPD-DS）占0.1%、胃袖状切除联合十二指肠空肠旁路术（SG-DJB）占0.1%、其他手术方式共117例（1.7%）。30.1%的病人在术前合并2型糖尿病，70.4%的病人术前合并阻塞型睡眠呼吸暂停低通气综合征，22.5%合并多囊卵巢综合征，18.8%合并反流性食管炎。结论 大中华减重与代谢手术数据库的搭建为中国减重代谢手术的大数据登记工作奠定了坚实基础。基于目前数据，尽管手术方式呈现多样性，SG仍是本年度中国多地区减重与代谢手术的主流术式。更多还原

【Abstract】 Objective To summarize the metabolic and bariatric surgery cases performed in China in 2021. Methods The data of this observational study was extracted from the Greater China Metabolic and Bariatric Surgery Database(GCMBD) to evaluate the prevalence of metabolic and bariatric surgery in China. Demographic characteristics, obesityrelated diseases, and operational information were analyzed. Results In 2021, a total of 53 centers from 21 provinces/province-level municipalities in China registered 6807 cases. The patients’ median(minimum, maximum) BMI before the surgery was 36.8(21.0, 87.5). The proportion of female patients was 75.1%, with a median(minimum, maximum) age of 32(9, 72) years, while the male was 24.9%, with a median(minimum, maximum) age of 33(11, 65) years. Among all procedures, 84.9% were sleeve gastrectomy(SG), 3.1% Roux-en-Y gastric bypass(RYGB), 4.2% sleeve gastrectomy with jejunojenunal bypass(SG-JJB), 3.5% one anastomosis gastric bypass(OAGB), 1.7% sleeve gastrectomy with transit bipartition, 0.4% sleeve gastrectomy with loop duodenojejunal bypass(SG-LDJB), 0.3% single-anastomosis duodenalileal bypass with sleeve gastrectomy(SADI-S), 0.1% biliopancreatic diversion with duodenal switch(BPD-DS), 0.1%sleeve gastrectomy with duodenojejunal bypass(SG-DJB), and 1.7% other operation types. Thirty percent of patients had history of type 2 diabetes, 70.4% had obstructive sleep apnea-hypopnea syndrome(OSAHS), 22.5% had polycystic ovary syndrome(PCOS), and 18.8% had reflux esophagitis(RE) before operation. Conclusion The establishment of GCMBD has laid a solid foundation for clinical data registration in China. Based on the analysis of the year 2021 data, SG is still the most performed procedure in China despite a variety of surgical procedures being recorded.更多还原
