Aims: To investigate whether preoperative enteral diets -enriched in eicosapentaenoic acid (EPA) supplements could reduce the incidence of hypercytokinemia after pancreatoduodenectomy (PD) in a double-blinded randomized -controlled trial. Methods: Patients with resectable periampullary cancer were randomized into either the control group or the treatment group. Patients in the treatment group received oral supplementation (600 kcal/day) containing EPA for 7 days before surgery. Patients in the control group received isocaloric isonitrogenous standard nutrition (600 kcal/day) without EPA for 7 days before surgery. The primary endpoint was postoperative serum concentrations of interleukin-6 (IL-6). The secondary endpoints were the postoperative nutritional status and the incidence of postoperative infectious complications. Results: Twenty-four patients were enrolled in the present study. After exclusion, 20 patients (control group, n = 9; treatment group, n = 11) were analyzed. There were no significant differences in the curves for the serum concentration of IL-6 (p = 0.68) or the incidence of infectious complications between the 2 groups (control group: 78%, treatment group: 55%, p = 0.37). Conclusions: The results of a double-blinded randomized controlled trial indicated that preoperative immunonutrition had no marked impact on the rates of postoperative hypercytokinemia or infectious complications after PD.
