Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Objectives</title> <p>Nutritional deficiencies and immune dysfunction in cancer patients may contribute to postoperative septic morbidity. This trial compared the effects of perioperative enteral immunonutrition (EIN) versus standard enteral nutrition (SEN) on systemic and mucosal immunity in patients undergoing pancreaticoduodenectomy for periampullary cancer.</p> </sec> <sec> <title>Methods</title> <p>Thirty-seven patients were randomized (EIN, n = 17; SEN, n = 20) to receive feed for 14 days preoperatively and 7 days postoperatively. Mediators of systemic immunity (interleukin 1α, tumor necrosis factor α, lymphocytes subsets, and complement components) and of mucosal immunity in duodenal biopsies, nutritional markers and parameters were evaluated.</p> </sec> <sec> <title>Results</title> <p>The groups were comparable for demographics, the concentrations of mediators of systemic and mucosal immunity at time of recruitment, and for the duration and amount of feed received. Preoperative EIN rather than SEN was associated with significant reductions in plasma tumor necrosis factor α and total hemolytic complement. Enteral immunonutrition–fed patients had significantly higher total lymphocyte count on the third postoperative day and significantly greater rise in CD4/CD8 ratio from day 3 to day 7 postoperatively compared with SEN-fed patients.</p> </sec> <sec> <title>Conclusions</title> <p>The perioperative administration of EIN rather than SEN is associated with a favorable modulation of the inflammatory response and enhancement of systemic immunity in patients undergoing pancreaticoduodenectomy for periampullary cancer.</p> </sec> </abstract>
