Abstract
BACKGROUND We have reported that perioperative and preoperative immunonutrition reduced infectious complications in patients undergoing pancreaticoduodenectomy; however, it is unclear whether perioperative immunonutrition has additional effects compared with preoperative immunonutrition. The present study evaluated whether perioperative, compared with preoperative, immunonutrition has additional effects on cell-mediated immunity and the infection rate after pancreaticoduodenectomy. MATERIALS AND METHODS This was a prospective, randomized clinical trial conducted in our institution. Oral supplementation enriched with arginine, ω-3 fatty acids, and dietary nucleotides was given by enteral infusion to 30 patients before and after surgery (perioperative group); 30 patients received the same enriched formula before surgery and standard enteral nutrition following surgery (preoperative group). The primary endpoint was concanavalin (Con A)- or phytohemagglutinin (PHA)-stimulated lymphocyte proliferation on postoperative day (POD) 7, which is an index of cell-mediated immunity; the secondary endpoint was the postoperative infection rate. RESULTS There were no significant differences in Con A- or PHA-stimulated lymphocyte proliferation on POD 7 between the groups. There was no significant difference in the postoperative infection rate between the two groups. In the post hoc subgroup analysis, with respect to the effect on the infection rate, a significant interaction was found only between a long operative time and perioperative immunonutrition. CONCLUSIONS There were no additional effects of perioperative, compared with preoperative, immunonutrition on postoperative immunity and infectious complications in patients undergoing pancreaticoduodenectomy.

Abstract
OBJECTIVE To compare the outcomes of early oral feeding (EOF) and the traditional oral feeding (TOF) in postoperative patients with colorectal cancer using Meta-analysis. METHODS The databases of PubMed, SCI, Ovid, The Cochrane Library, CNKI, CBM, VIP and Wanfang Data were searched to collect randomized controlled trial (RCT) about EOF versus TOF in patients undergoing elective colorectal surgery. The retrieval time span was from inception to June 1, 2016. The studies were screened according to the inclusion and exclusion criteria. The data were extracted and the quality was evaluated by 2 reviewers independently. The Meta-analysis was conducted using RevMan 5.2 software. RESULTS A total of 14 studies with 1 807 patients (906 cases in EOF group and 901 cases in TOF group) were included. The time to first passage of flatus (MD=-16.11 h, 95%CI:-18.27 to -13.94 h, P=0.00), postoperative hospital stay (MD=-1.92 d, 95%CI:-2.83 to -1.01 d, P=0.00), hospitalization cost (ten thousand yuan) (MD=-0.58, 95%CI:-0.71 to -0.46, P=0.00) were less in EOF group compared to TOF group. EOF patients had lower total complication rate (OR=0.68, 95%CI:0.48 to 0.95, P=0.03), in which the pulmonary infection (OR=0.27, 95%CI:0.13 to 0.53, P=0.00), pharyngolaryngitis (OR=0.06, 95%CI:0.04 to 0.11, P=0.00) were lower than those in TOF group, while the tube reinsertion (OR=2.34, 95%CI:1.08 to 5.07, P=0.03) was higher. The incidence of anastomotic leakage, nausea, vomiting, abdominal distension, diarrhea, and wound infection between two groups was not significantly different(all P>0.05). There was no significant difference between two groups in IgM (P>0.05), while the IgA (MD=0.3, 95%CI:0.12 to 0.48, P=0.00), IgG (MD=2.13 ,95%CI:0.82 to 3.44, P=0.001), CD4+ (MD=3.80, 95%CI:2.55 to 5.04, P=0.00), CD4+/CD8+ (MD=0.22, 95%CI:0.04 to 0.41, P=0.02) in EOF group were higher than those in TOF group. Postoperative CRP decreased rapidly in EOF group (MD=-30.10, 95%CI:-48.07 to -12.13, P=0.00), and IL-6 was not significantly different (P>0.05). EOF patients had higher serum albumin level 5 days after operation (MD=3.27, 95%CI: 2.48 to 4.07, P=0.00). CONCLUSIONS EOF can promote gas passage and defecation, reduce postoperative hospital stay and treatment costs. Also, it can decrease the incidence of complications and postoperative inflammation, and maintain immune function.

Shields, BA, Brown, JN, Aden, JK, Salgueiro, M, Mann-Salinas, EA, Chung, KK
Burns : journal of the International Society for Burn Injuries. 2014;(8):1587-92
Abstract
Severe weight loss resulting from inadequate nutritional intake along with the hypermetabolism after thermal injury can result in impaired immune function and delayed wound healing. This observational study was conducted on adults admitted between October 2007 and April 2012 with at least 20% total body surface area burn requiring excision who previously tolerated gastric enteral nutrition at calorie goal and who returned from surgery hemodynamically stable (no new pressor requirement) and compared the effect of goal rate re-initiation versus slow re-initiation after the first excision and grafting. Demographic, intake, and tolerance data were collected during the 36h following surgery and were analyzed with descriptive and comparative statistics. Data were collected on 14 subjects who met the inclusion criteria. Subjects in the goal rate re-initiation group (n=7) met a significantly greater percentage of caloric goals (99±12% versus 58±21%, p=0.003) during the 36h following surgery than subjects in the slow re-initiation group (n=7). There were no incidences of emesis, aspiration, or ischemic bowel in either group. The goal rate re-initiation group had a 29% incidence of either stool output >1L (n=1) or gastric residual volumes >500mL (n=1), whereas these were not present in the slow re-initiation group (p=0.462). In conclusion, in this small pilot study, we found that enteral nutrition could be re-initiated after the first excision and grafting in those patients who previously tolerated gastric enteral nutrition meeting caloric goals who return from surgery hemodynamically stable without a significant difference in intolerance and with a significantly higher percentage of calorie goals achieved, but larger studies are required.

Abstract
A best evidence topic in surgery was written according to a structured protocol. The question addressed was "In cancer patients undergoing oesophageal or gastric resection for cancer and requiring postoperative nutritional support, does enteral immunonutrition confer additional clinical benefits as compared to standard enteral nutrition? Two hundred and fifty-eight papers were identified by a search of the MEDLINE and EMBASE databases, of which six randomized controlled trials represented the best evidence to answer this clinical question. The authors, journal, date and country of publication, patient group, study group, relevant outcomes and results of these papers were tabulated. All six of these randomised controlled trials compared the clinical benefits of standard enteral nutrition with those of enteral nutrition supplemented with a variety of immune-modulating substances. The studies failed to demonstrate consistent differences in patients' postoperative clinical course, complications, length of hospital stay and inflammatory marker levels. Hence although there is reasonable evidence to suggest that immunonutrition improves humoral immunity as opposed to cellular immunity, this improvement does not result in reductions in infection rates or reduced hospital stay. There is currently not enough evidence to recommend routine immunonutrition in all patients undergoing oesophageal or gastric resection for cancer.

Abstract
BACKGROUND Oesophagogastric cancer surgery is immunosuppressive. This may be modulated by omega-3 fatty acids (O-3FAs). The aim of this study was to assess the effect of perioperative O-3FAs on clinical outcome and immune function after oesophagogastric cancer surgery. METHODS Patients undergoing subtotal oesophagectomy and total gastrectomy were recruited and allocated randomly to an O-3FA enteral immunoenhancing diet (IED) or standard enteral nutrition (SEN) for 7 days before and after surgery, or to postoperative supplementation alone (control group). Clinical outcome, fatty acid concentrations, and HLA-DR expression on monocytes and activated T lymphocytes were determined before and after operation. RESULTS Of 221 patients recruited, 26 were excluded. Groups (IED, 66; SEN, 63; control, 66) were matched for age, malnutrition and co-morbidity. There were no differences in morbidity (P = 0·646), mortality (P = 1·000) or hospital stay (P = 0·701) between the groups. O-3FA concentrations were higher in the IED group after supplementation (P < 0·001). The ratio of omega-6 fatty acid to O-3FA was 1·9:1, 4·1:1 and 4·8:1 on the day before surgery in the IED, SEN and control groups (P < 0·001). There were no differences between the groups in HLA-DR expression in either monocytes (P = 0·538) or activated T lymphocytes (P = 0·204). CONCLUSION Despite a significant increase in plasma concentrations of O-3FA, immunonutrition with O-3FA did not affect overall HLA-DR expression on leucocytes or clinical outcome following oesophagogastric cancer surgery.

Shintani, Y, Ikeda, N, Matsumoto, T, Kadota, Y, Okumura, M, Ohno, Y, Ohta, M
Asian cardiovascular & thoracic annals. 2012;(2):172-6
Abstract
Impaired nutrition is an important predictor of perioperative complications in lung cancer patients, and preoperative chemoradiotherapy increases the risk of such complications. The goal of this study was to assess the effect of an immune-enhancing diet on nutritional status in patients undergoing lung resection after chemoradiotherapy. We compared the preoperative nutritional status in 15 patients with lung cancer undergoing lung resection without chemoradiotherapy and 15 who had chemoradiotherapy. Body mass index and lymphocyte counts were lower in patients who had chemoradiotherapy. Although there was no difference in the rate of postoperative morbidity between groups, the chemoradiotherapy patients were more likely to have severe complications postoperatively. After chemoradiotherapy in 12 patients, 6 received oral Impact for 5 days, and 6 had a conventional diet before surgery. Oral intake of Impact for 5 days before surgery modified the decrease in transferrin and lymphocytes after the operation. Preoperative immunonutrition may improve the perioperative nutritional status after induction chemoradiotherapy in patients undergoing lung cancer surgery, and reduce the severity of postoperative complications. These potential benefits need to be confirmed in a randomized controlled trial.

Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. 2010;(3):153-61
Abstract
INTRODUCTION current studies suggest immunonutrition decreases the inflammatory process, infection rates and reduces length of hospital stay in surgical patients, however studies are often conducted on heterogeneous groups of patients with varying composition of the immuno-nutrition. We aim to investigate the effect of immunonutrition on patients undergoing major upper gastrointestinal surgery by assessment of (i) the inflammatory and immune response and (ii) changes in clinical outcome when compared to a randomised control receiving conventional feeding. METHOD a prospective double-blind randomised controlled study was undertaken to compare a feed supplemented with glutamine, arginine, -3 fatty acids and tributyrin, vitamin C, E and B-carotene and micronutrients (zinc, selenium and chromium) to an isonitrogenous, isocaloric control feed in patients undergoing major upper GI surgery. The primary end-points were defined as C-reactive protein (CRP), prealbumin and retinol binding protein (RBP) levels. Secondary end-points included performance scoring systems, length of hospital stay, adverse events and protein and nutrient assays. Variables were measured pre-operatively and routinely up to the 4th post-operative day. RESULTS there was no statistically significant change in primary end-points between the immunonutrition group and the control group. There was no difference in length of hospital stay between the groups. The vitamin C level in the study group was significantly higher at the end of the study period. Both groups tolerated the feeds well with adequate target feeding rate. There were no other significant changes in clinical outcomes between the two groups. CONCLUSION this study has not shown a benefit of immunonutrition through changes in inflammatory or nutritional markers, a decrease in length of hospital stay, or other morbidity. This may be because of inadequate numbers recruited to the study. Further, multi-centre, randomised trials on homogeneous patient groups are necessary to investigate the role of immunonutrition in major upper GI surgery.

Postsurgical infections are reduced with specialized nutrition support.
Waitzberg, DL, Saito, H, Plank, LD, Jamieson, GG, Jagannath, P, Hwang, TL, Mijares, JM, Bihari, D
World journal of surgery. 2006;(8):1592-604
Abstract
OBJECTIVE The objective was to examine the relationship between pre-, peri-, and postoperative specialized nutritional support with immune-modulating nutrients and postoperative morbidity in patients undergoing elective surgery. METHODS Studies were identified by searching MEDLINE, review article bibliographies, and abstracts and proceedings of scientific meetings. All randomized clinical trials in which patients were supplemented by the IMPACT formula before and/or after elective surgery and the clinical outcomes reported were included in the meta-analysis. Seventeen studies (n=2,305), 14 published (n=2,102), and 3 unpublished (n=203), fulfilled the inclusion criteria. Ten studies (n=1,392) examined the efficacy of pre- or perioperative IMPACT supplementation in patients undergoing elective surgery, whereas 7 (n=913) assessed postoperative efficacy. Fourteen of the studies (n=2,083) involved gastrointestinal (GI) surgical patients. Postoperative complications, mortality, and length of stay in hospital (LOS) were major outcomes of interest. RESULTS IMPACT supplementation, in general, was associated with significant (39%-61%) reductions in postoperative infectious complications and a significant decrease in LOS in hospital by an average of 2 days. The greatest improvement in postoperative outcomes was observed in patients receiving specialized nutrition support as part of their preoperative treatment. In GI surgical patients, anastomotic leaks were 46% less prevalent when IMPACT supplementation was part of the preoperative treatment. CONCLUSION This study identifies a dosage (0.5-1 l/day) and duration (supplementation for 5-7 days before surgery) of IMPACT that contributes to improved outcomes of morbidity in elective surgery patients, particularly those undergoing GI surgical procedures. The cost effectiveness of such practice is supported by recent health economic analysis. Findings suggest preoperative IMPACT use for the prophylaxis of postoperative complications in elective surgical patients.

Enteral nutrition and oral nutrition supplements: a review of the economics literature.
Pritchard, C, Duffy, S, Edington, J, Pang, F
JPEN. Journal of parenteral and enteral nutrition. 2006;(1):52-9
Abstract
BACKGROUND We sought to review the economics literature on enteral nutrition (EN) and oral nutrition supplements (ONS) against the background of an ongoing clinical guideline development. METHODS We searched the Health Economic Evaluations Database, the NHS Economic Evaluation Database, and the Cochrane Database of Systematic Reviews. RESULTS Enteral vs parenteral nutrition was found to be the most common comparison undertaken. The randomized trial evidence suggests that, in some groups of patients, EN is better in terms of clinical endpoints and/or length of hospital stay. This should translate into a lower mean cost for EN, given the reduced daily cost. These studies should be treated with caution because of their small sample size and poor quality. Costing was often crude and poorly reported, tending to focus on the narrow costs of the nutrition supplements. Only 1 study of a nutrition supplement in the community setting was found. CONCLUSIONS There is some evidence to indicate economic advantages of enteral over parenteral nutrition and of immune-enhancing supplements relative to control diet. There is a lack of well-designed studies taking a broad view of relevant comparators, costs, and outcomes. The cost-effectiveness of different forms of nutrition in different patient groups remains to be established.

Briassoulis, G, Filippou, O, Kanariou, M, Hatzis, T
Intensive care medicine. 2005;(6):851-8
Abstract
OBJECTIVE To compare the effect of early enteral feeding using immune-enhancing (IE) vs. non-immune-enhancing (NIE) formulas on cytokines in children with septic shock. DESIGN AND SETTING A single-center, randomized, blinded controlled trial in a pediatric intensive care unit of a university hospital. PATIENTS We randomized 38 patients with septic shock to either IE or NIE. Feedings were advanced to a target volume of energy intake equal to 1/2, 1, 5/4, 6/4, and 6/4 of the predicted basal metabolic rate on days 1-5, respectively. MEASUREMENTS AND RESULTS Interleukins (IL) 1beta, 6, and 8, tumor necrosis factor alpha, C-reactive protein, Pediatric Risk of Mortality (PRISM) score, survival, secondary infections, length of stay, and mechanical ventilation were compared within and between the two groups. Actual mean energy and protein intakes did not differ between the two groups and the caloric-protein balance was not correlated to cytokine levels. On day 5 IL-6 levels were significantly lower (11.8+/-2.4 vs. 38.3+/-3.6) and IL-8 significantly higher in the IE than in the NIE group (65.4+/-17 vs. 21+/-2.5). After 5 days of nutritional support a significant decrease in IL-6 levels was recorded only in group IE (mean of paired differences 39.4+/-3 pg/ml). In multivariate regression analysis the variation in cytokines was independently correlated only to PRISM (R(2)=-0.50), but pediatric intensive care unit outcome endpoints did not differ between the two groups. CONCLUSIONS Early IE nutrition may modulate cytokines in children with septic shock, but there is no evidence that this immunomodulation has any impact on short-term outcome.
