Abstract: 【Abstract】 Pancreaticoduodenectomy （PD） contributes to 30%- 50% of morbidity, mainly including postoperative pancreatic fistula （POPF），postpancreatectomy hemorrhage （PPH），infectious complication and delayed gastric emptying（DGE）. Patients who have undergone pancreaticoduodenectomy often present perioperative malnutrition that is worse in the early postoperative days，and affects the number of postoperative complications. Few studies focus on the relation between enteral nutrition（EN）and post? operative complications. Our aim was to perform a review，including only randomized controlled trial （RCT）or well?designed studies，of evidence regarding the correlation between EN and main complications after pancreatico duodenectomy.

摘要： 【摘要】胰十二指肠切除术（PD）存在30%～50%合并症，主要包括术后胰瘘、残胰出血、感染及胃排空延迟等。PD术后患者常出现围手术期营养失调，尤其术后早期，并影响并发症发生率。迄今，较少研究聚焦于肠内营养（EN）与PD术后并发症的关联性。本文旨在综述至今仅有的随机对照研究和设计良好的研究证据，探索EN与PD术后主要并发症的相关性。
