腸內或稱經腸營養(enteral nutrition)是經胃腸道用口服或管飼來提供可滿足、超過或補充代謝需要的營養基質及其他各種營養素的營養方式［1］。經過漫長的臨床實踐與技術發展，腸內營養的優越性越來越為人們所重視。“如果腸道有功能，就應使用腸道”的原則已為大多數臨床醫師所接受。近年來外科術后早期腸內營養（early enteral nutrition）的研究亦有較多的進展。
The diagnosis and treatment of gastric cancer is a systematic and frameworking medical task in a multidisciplinary manner. New models, new technologies, new regimens, and new drugs have been developed to explore the best strategies to improve the survival of patients with gastric cancer. Here we discussed the research progress and guideline updates in four aspects, including the accurate staging-classification-based treatment strategy, the quality control in the surgery, the rational perioperative neoadjuvant-adjuvant therapies, and molecular classification joint with precision medicine. The purpose is to further promote the standardized gastric cancer management in China and emphasize its importance. From the updates of knowledge and the transformation of understanding and recognition, to the quality improvement, it’s critical to reduce the heterogeneity of the quality of gastric cancer management in China, as well as enhance adherence to guidelines and consensuses.
The incidence of esophagogastric junction adenocarcinoma is gradually increasing, and gastrointestinal surgery and thoracic surgery are paying more and more attention to its surgical treatment. “Chinese expert consensus on the surgical treatment of adenocarcinoma of esophagogastric junction (2018 edition)” discussed the core issues in the field of surgical treatment such as definition, classification, surgical approach, lymphadenectomy, digestive tract reconstruction, and neoadjuvant therapy for esophagogastric junction adenocarcinoma, and gave recommendations. However, there is still some controversy about these issues. The author discussed the consensus and controversial issues relevant to esophagogastric junction adenocarcinoma and related research progress in recent years.
