Abstract
Background
Although early enteral nutrition (EEN) is an accepted practice after pancreaticoduodenectomy (PD), the impact of EEN on postoperative complications or nutritional status remains unclear. We aimed to investigate the impact of EEN on delayed gastric emptying (DGE) and nutritional status after PD.
Methods
A total of 143 patients underwent PD between January 2012 and September 2020. We excluded patients who underwent a two-stage pancreatojejunostomy, in whom the enteral tube was accidentally pulled out, or with insufficient information in their medical records. The incidence of postoperative complications was compared between patients who received EEN (EEN group, n = 21) and those who did not (control group, n = 21) after propensity score matching. Univariate and multivariate analyses were performed to identify the risk factors affecting the incidence of these complications. Nutritional status was assessed at postoperative months 1, 3, and 6.
Results
The incidence of grade B/C DGE in the EEN group was significantly lower than that in the control group (4.8% vs. 28.6%, p = 0.03). There was no significant difference in overall morbidity, incidence of any other postoperative complications, or all-grade DGE. In multivariate analysis, EEN was associated with a reduction in the incidence of grade B/C DGE (p < 0.01). In the analysis of nutritional status, EEN was significantly associated with better nutritional status at postoperative month 1.
Conclusion
EEN can lead to a lower clinically relevant DGE rate and better nutritional status in the early postoperative period in patients undergoing PD.
