The present review addresses data from randomized clinical trials on perioperative nutrition in patients with gastrointestinal cancer. It is important to appreciate that different approaches can be used with regard to timing of administration of nutritional support (preoperative versus postoperative), route of administration (parenteral versus enteral) and composition of the admixtures given (standard versus immune-enriched diets). The rationale underlying these approaches may also vary, and may include correction of nutritional status, attenuation of the acute-phase response through better preservation of gut function, and potentiation of the immune response.
本综述探讨了关于胃肠道癌患者围手术期营养的随机临床试验数据。必须认识到，在营养支持的给药时机（术前与术后）、给药途径（肠外与肠内）以及所给予的混合制剂成分（标准饮食与免疫增强饮食）方面，可以采用不同的方法。这些方法背后的基本原理也可能不同，可能包括纠正营养状况、通过更好地保护肠道功能减轻急性期反应以及增强免疫反应。
