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.

Key words: postoperative pancreatic fistula, pancreaticoduodenectomy, infectious complication, enteral nutrition, postpancreatectomy hemorrhage, delayed gastric emptying
