Enteral versus parenteral nutrition in patients undergoing pancreaticoduodenectomy: A meta-analysis of randomized controlled trial

摘要

Nutrition support have undergone total parenteral nutrition (TPN) in postoperative patients indecades, Recent studies have elaborated that the advantages of early enteral nutrition (EEN) inreducing complications incidence [1,2], however, some studies have claimed that EEN was insignificantin decreasing complication after abdominal surgery [3,4]; thus, the role of EN remains debatable.Current evidence was limited and inconclusive. To determine the safety and effectiveness of EN forpatients after pancreaticoduodenectomy (PD), we performed an up-to-date meta-analysis to EN versusPN route after pancreaticoduodenectomy including all randomized clinical trials on the impact onnutritional status and postoperative complications of the patients.
