Postoperative nutritional support after pancreaticoduodenectomy in adults

When compared with parenteral nutrition, enteral nutrition by jejunostomy likely results in a decreased length of hospital stay and may lead to no difference in the incidence of postoperative complications. When compared with parenteral nutrition, enteral feeding by nasojejunal tube may result in no difference in the incidence of postoperative complications or length of hospital stay. When compared with oral nutrition, enteral nutrition by jejunostomy feeding may result in no difference in the incidence of postoperative complications or length of hospital stay, but the evidence is very uncertain. Further high-quality research is required and there are several ongoing studies. Given the number of different nutritional interventions available in the postoperative setting, a network meta-analysis would be more appropriate in future.
