[The consensus on nutritional and multi-disciplinary management for bariatric surgery].

Obesity is associated with many chronic diseases and has become a major public health problem all over the world. Although weight loss includes lifestyle modification, psychological and medical treatment, bariatric surgery remains an effective treatment for morbidly obese patients. Due to the lack of multidisciplinary management and long-term nutrition monitoring, some patients are suffering from malnutrition, functional impairment and other issues after bariatric surgery. This consensus is commissioned by the Nutrition and Metabolism Cooperation Group of Chinese Society for Parenteral and Enteral Nutrition and Bariatric Multidisciplinary Team of Peking Union Medical College Hospital. This consensus summarizes the latest research results and refers to some recommendations in guidelines both at home and abroad. The detailed evidence-based recommendations allow for nuance-based clinical decision-making that addresses the multiple aspects of real-world medical care of patients with obesity to develop consensus on bariatric surgery and nutritional management among obese patients in multidisciplinary mode, including preoperative evaluation, perioperative management, postoperative long-term follow-up and nutritional management. The goal is to facilitate high-quality care of patients with obesity and provide a rational, scientifically based approach to management that optimizes health outcomes and safety.肥胖症与诸多代谢性疾病等慢性病的发生密切相关，已成为全球公认的导致人类死亡的重要原因。尽管减重治疗包括行为、心理及药物治疗等多种手段，但对中重度肥胖治疗效果有限。减重手术是近十余年来国内外临床研究公认的有效的中重度肥胖治疗手段，但由于国内缺乏减重手术的多学科管理特别是长期的营养管理监测，减重手术后患者面临营养不良、复胖、功能损害等问题。中华医学会肠外肠内营养学分会营养与代谢协作组与北京协和医院减重多学科协作组参照我国减重手术相关领域专家指导意见，结合国内外最新理论和指南，编写多学科模式下的中重度肥胖患者减重手术与营养管理共识，包括手术决策相关评估、围手术期管理、术后中长期随访与营养管理、减重手术后妊娠相关共识4部分，为减重手术相关多学科健康管理提供科学、合理的专家意见。.
