摘要减重代谢手术通过限制食物摄入和减少营养物质吸收，可降低体重并改善2型糖尿病、高血压、睡眠呼吸暂停综合征等肥胖相关代谢性疾病。腹腔镜胃袖状切除术、Roux-en-Y胃旁路术、可调节胃束带术和胆胰分流-十二指肠转位术是目前4种主流术式。胃袖状切除联合手术、单吻合口胃旁路术、胃内球囊及内镜下减重手术等创新术式也不断涌现。目前，减重代谢手术正迎来学科深度融合、术式优化创新、减重降糖疗效确切的发展机遇期，必将使更多肥胖患者临床获益。

abstractsBariatric-metabolic surgery (BMS) has the potential of decreasing body weight and improving obesity-related metabolic syndrome by restricting food intake and malabsorption. Laparoscopic sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, biliopancreatic diversion with duodenal switch are four major BMS procedures. Sleeve plus surgery, one-anastomosis gastric bypass, intragastric balloon and endoscopic surgery are also arising and gaining popularity due to their specific efficacy. Currently, BMS is now experiencing an era with deeply integrated interdisciplinarity, optimizing and innovating of surgeries and well-illustrated clinical efficacy, as a result, more obese patients would benefit from BMS.
