Abstract
BACKGROUND Poor preoperative nutritional status has been consistently linked to an increase in postoperative complications and worse surgical outcomes. We updated a review first published in 2012. OBJECTIVES To assess the effects of preoperative nutritional therapy compared to usual care in people undergoing gastrointestinal surgery. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, three other databases and two trial registries on 28 March 2023. We searched reference lists of included studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) of people undergoing gastrointestinal surgery and receiving preoperative nutritional therapy, including parenteral nutrition, enteral nutrition or oral nutrition supplements, compared to usual care. We only included nutritional therapy that contained macronutrients (protein, carbohydrate and fat) and micronutrients, and excluded studies that evaluated single nutrients. We included studies regardless of the nutritional status of participants, that is, well-nourished participants, participants at risk of malnutrition, or mixed populations. We excluded studies in people undergoing pancreatic and liver surgery. Our primary outcomes were non-infectious complications, infectious complications and length of hospital stay. Our secondary outcomes were nutritional aspects, quality of life, change in macronutrient intake, biochemical parameters, 30-day perioperative mortality and adverse effects. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. We assessed risk of bias using the RoB 1 tool and applied the GRADE criteria to assess the certainty of evidence. MAIN RESULTS We included 16 RCTs reporting 19 comparisons (2164 participants). Seven studies were new for this update. Participants' ages ranged from 21 to 79 years, and 62% were men. Three RCTs used parenteral nutrition, two used enteral nutrition, eight used immune-enhancing nutrition and six used standard oral nutrition supplements. All studies included mixed groups of well-nourished and malnourished participants; they used different methods to identify malnutrition and reported this in different ways. Not all the included studies were conducted within an Enhanced Recovery After Surgery (ERAS) programme, which is now current clinical practice in most hospitals undertaking GI surgery. We were concerned about risk of bias in all the studies and 14 studies were at high risk of bias due to lack of blinding. We are uncertain if parenteral nutrition has any effect on the number of participants who had a non-infectious complication (risk ratio (RR) 0.61, 95% confidence interval (CI) 0.36 to 1.02; 3 RCTs, 260 participants; very low-certainty evidence); infectious complication (RR 0.98, 95% CI 0.53 to 1.80; 3 RCTs, 260 participants; very low-certainty evidence) or length of hospital stay (mean difference (MD) 5.49 days, 95% CI 0.02 to 10.96; 2 RCTs, 135 participants; very low-certainty evidence). None of the enteral nutrition studies reported non-infectious complications as an outcome. The evidence is very uncertain about the effect of enteral nutrition on the number of participants with infectious complications after surgery (RR 0.90, 95% CI 0.59 to 1.38; 2 RCTs, 126 participants; very low-certainty evidence) or length of hospital stay (MD 5.10 days, 95% CI -1.03 to 11.23; 2 RCTs, 126 participants; very low-certainty evidence). Immune-enhancing nutrition compared to controls may result in little to no effect on the number of participants experiencing a non-infectious complication (RR 0.79, 95% CI 0.62 to 1.00; 8 RCTs, 1020 participants; low-certainty evidence), infectious complications (RR 0.74, 95% CI 0.53 to 1.04; 7 RCTs, 925 participants; low-certainty evidence) or length of hospital stay (MD -1.22 days, 95% CI -2.80 to 0.35; 6 RCTs, 688 participants; low-certainty evidence). Standard oral nutrition supplements may result in little to no effect on number of participants with a non-infectious complication (RR 0.90, 95% CI 0.67 to 1.20; 5 RCTs, 473 participants; low-certainty evidence) or the length of hospital stay (MD -0.65 days, 95% CI -2.33 to 1.03; 3 RCTs, 299 participants; low-certainty evidence). The evidence is very uncertain about the effect of oral nutrition supplements on the number of participants with an infectious complication (RR 0.88, 95% CI 0.60 to 1.27; 5 RCTs, 473 participants; very low-certainty evidence). Sensitivity analysis based on malnourished and weight-losing participants found oral nutrition supplements may result in a slight reduction in infections (RR 0.58, 95% CI 0.40 to 0.85; 2 RCTs, 184 participants). Studies reported some secondary outcomes, but not consistently. Complications associated with central venous catheters occurred in RCTs involving parenteral nutrition. Adverse events in the enteral nutrition, immune-enhancing nutrition and standard oral nutrition supplements RCTs included nausea, vomiting, diarrhoea and abdominal pain. AUTHORS' CONCLUSIONS We were unable to determine if parenteral nutrition, enteral nutrition, immune-enhancing nutrition or standard oral nutrition supplements have any effect on the clinical outcomes due to very low-certainty evidence. There is some evidence that standard oral nutrition supplements may have no effect on complications. Sensitivity analysis showed standard oral nutrition supplements probably reduced infections in weight-losing or malnourished participants. Further high-quality multicentre research considering the ERAS programme is required and further research in low- and middle-income countries is needed.

Abstract
Additional preoperative programmes may be beneficial for candidates who seek bariatric surgery, but there is no consensus on the optimal preparation. This systematic review aimed to summarize the effects of a preoperative programme on weight loss. A literature search was performed for Embase, Cinahl, PubMed and Cochrane Library. Studies on preoperative exercise, behaviour and/or diet programmes administered in adult patients in a bariatric trajectory measuring weight loss were included. Initial results yielded 2148 titles, 70 of which were thoroughly analysed and 37 articles were included, comprising 10 333 patients. Eleven out of 37 studies included postoperative weight loss as an outcome in interventions focused on diet (n = 5), behaviour (n = 2), exercise (n = 2) and a combination of interventions (n = 2). Only one study (9%) which administered exercise as a preoperative programme showed a significant effect on postoperative weight loss. In total, 33 studies included preoperative weight loss as an outcome, which was significant in 64% of the cases. It is difficult to draw conclusions from the investigated data as it was extremely heterogeneous concerning the intensity, duration and administration of a programme. Nevertheless, it seems that a preoperative weight loss programme seems beneficial in terms of preoperative weight loss, postoperative physical activity and improved mental health postinterventional. The use of a core outcome set is recommended for future studies.

Abstract
BACKGROUND The aim of this study was to investigate the influence of obesity and the usefulness of a preoperative weight loss program (PWLP) for obese patients undergoing laparoscopic colorectal resection (LCR). METHODS Study 1: 392 patients who underwent LCR for colorectal cancer were divided into two groups: those with a body mass index (BMI) ≥25 kg/m2 (n = 113) and those with a BMI <25 kg/m2 (n = 279). The influence of BMI on LCR was investigated. Study 2: Patients with a BMI ≥28 kg/m2 who were scheduled to undergo LCR (n = 7, mean body weight 87.0 kg, mean BMI 33.9 kg/m2) undertook a PWLP including caloric restriction and exercise for 29.6 (15-70) days. The effects of this program were evaluated. RESULTS Study 1: The BMI ≥25 kg/m2 group had a prolongation of operation time and hospital stay than the BMI <25 kg/m2 group. Study 2: The patients achieved a mean weight loss of 6.9% (-6.0 kg). The mean visceral fat area was significantly decreased by 18.0%, whereas the skeletal muscle mass was unaffected. The PWLP group had a significantly lower prevalence of postoperative complications compared with the BMI ≥25 kg/m2 group. CONCLUSION Obesity affected the surgical outcomes in LCR. A PWLP may be useful for obese patients undergoing LCR.

Abstract
Introduction Surgical stress predisposes patients to have immune dysfunction and an increased risk of infection. Malnourished surgical patients have higher postoperative morbidity and mortality rates, higher readmission rates, and higher hospital costs. The use of an immunomodulatory formula is associated in the ESPEN guidelines with a reduction in wound healing problems, suture failure, and infectious and global complications. Several authors have suggested that, since most clinical trials evaluating the efficacy of immunonutrition have been carried out in a traditional perioperative setting, it would be interesting to investigate its efficacy in a more controlled setting, such as in the ERAS (Enhanced Recovery after Surgery) protocol. The objective of this work was: a) to define the role that immunonutrition should play in ERAS protocols based on the best scientific evidence available; b) to analyze the difficulties that continue to exist in real-life clinical practice to screen the nutritional risk of patients; c) to make a proposal of algorithms adapted to the characteristics of our environment regarding the screening, assessment, and nutritional treatment of surgical patients in fast-track surgery.

Abstract
Background Staple-line leaks following laparoscopic sleeve gastrectomy (LSG) remain a concerning complication. Staple-line buttressing is largely adopted as an acceptable reinforcement but data regarding leaks have been equivocal. This study compared staple-line leaks in five reinforcement options during LSG: no reinforcement (NO-SLR), oversewing (suture), nonabsorbable bovine pericardial strips (BPS), tissue sealant or fibrin glue (Seal), or absorbable polymer membrane (APM). Methods This systematic review study of articles published between 2012 and 2016 regarding LSG leak rates aligned with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Variables of interest included leak rates, bleeding, and complications in addition to surgical and population parameters. An independent Fisher’s exact test was used to compare the number of patients with and without leaks for the different reinforcement options. Results Of the 1633 articles identified, 148 met inclusion criteria and represented 40,653 patients. Differences in age (older in APM; p = 0.001), starting body mass index (lower in Suture; p = 0.008), and distance from pylorus (closer in BPS; p = 0.04) were observed between groups, but mean bougie size was equivalent. The overall leak rate of 1.5% (607 leaks) ranged from 0.7% for APM (significantly lower than all groups; p ≤ 0.007 for next lowest leak rate) to 2.7% (BPS). Conclusions This systematic review of staple-line leaks following LSG demonstrated a significantly lower rate using APM staple-line reinforcement as compared to oversewing, use of sealants, BPS reinforcement, or no reinforcement. Variation in surgical technique may also contribute to leak rates.

Abstract
BACKGROUND The essence of enhanced recovery after surgery (ERAS) program is the multimodal approach, and many authors have demonstrated safety and feasibility in fast-track bariatric surgery. OBJECTIVES The aim of this study was to evaluate the postoperative pain after the implementation of an ERAS protocol in Roux-en-Y gastric bypass and to compare it with the application of a standard care protocol. SETTING University Hospital Rey Juan Carlos, Madrid, Spain. METHODS A prospective randomized clinical trial of all the patients undergoing Roux-en-Y gastric bypass was performed. Patients were randomized into the following 2 groups: those patients after an ERAS program and those patients after a standard care protocol. Postoperative pain, nausea or vomiting, morbidity, mortality, hospital stay, and analytic acute phase reactants 24 hours after surgery were evaluated. RESULTS One hundred eighty patients were included in the study, 90 in each group. Postoperative pain (16 versus 37 mm; P < .001), nausea or vomiting (8.9% versus 2.2%; P = .0498), and hospital stay (1.7 versus 2.8 d; P < .001) were significantly lower in the ERAS group. There were no significant differences in complications, mortality, and readmission rates. White blood cell count, serum fibrinogen, and C reactive protein levels were significantly lower in the ERAS group 24 hours after surgery. CONCLUSION The implementation of an ERAS protocol was associated with lower postoperative pain, reduced incidence of postoperative nausea or vomiting, lower levels of acute phase reactants, and earlier hospital discharge. Complications, reinterventions, mortality, and readmission rates were similar to that obtained after a standard care protocol.

Abstract
BACKGROUND Preoperative weight loss is often encouraged before undergoing weight loss surgery. Controversy remains as to its effect on postoperative outcomes. The aim of this study was to determine what impact short-term preoperative excess weight loss (EWL) has on postoperative outcomes in patients undergoing primary vertical sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). STUDY DESIGN All patients who underwent SG (n = 167) or RYGB (n = 188) between 2014 and 2016 and who completed our program-recommended low calorie diet (LCD) for 4 weeks immediately preceding surgery were included. These patients (N = 355) were then divided into 2 cohorts and analyzed according to those who achieved ≥8% EWL (n = 224) during the 4-week LCD period and those who did not (n = 131). Primary endpoints included percent excess weight loss (% EWL) at 1, 3, 6, and 12 months postoperatively. RESULTS Patients achieving ≥8% EWL preoperatively experienced a greater % EWL at postoperative month 3 (42.3 ± 13.2% vs 36.1 ± 10.9%, p < 0.001), month 6 (56.0 ± 18.1% vs 47.5 ± 14.1%, p < 0.001), and month 12 (65.1 ± 23.3% vs 55.7 ± 22.2%, p = 0.003). Median operative duration (117 minutes vs 125 minutes; p = 0.061) and mean hospital length of stay (1.8 days vs 2.1 days; p = 0.006) were also less in patients achieving ≥8% EWL. No significant differences in follow-up, readmission, or reoperation rates were seen. Linear regression analysis revealed that patients who achieved ≥8% EWL during the 4-week LCD lost 7.5% more excess weight at postoperative month 12. CONCLUSIONS Based on these data, preoperative weight loss of ≥8% excess weight, while following a 4-week LCD, is associated with a significantly greater rate of postoperative EWL over 1 year, as well as shorter operative duration and hospital length of stay.

Abstract
BACKGROUND Achieving program-mandated preoperative weight loss poses a challenge for many bariatric surgery candidates. No systematic method exists to identify at-risk patients early in preoperative care. OBJECTIVES This study sought to explore predictors of preoperative weight loss achievement and to develop a treatment algorithm for guiding clinical decision-making. SETTING Greenville Health System, South Carolina. METHODS A retrospective chart review was conducted for 378 patients who followed a program-mandated low-calorie diet (LCD) for 4 weeks to achieve≥8% excess weight loss (EWL). Associations between weight loss achievement and patient demographic, nutrition, psychological, clinical, anthropometric, and treatment characteristics documented at 5 preoperative evaluation events were analyzed using logistic regression. RESULTS During the LCD, 62.7% of patients achieved≥8% EWL. Independent predictors of achievement (all P<.05) were male sex (OR 2.31, 95% CI 1.21-4.42), Caucasian race (OR 2.45, 95% CI 1.38-4.34), body mass index (BMI) at surgeon evaluation (50.0-59.9 kg/m2: OR .44, 95% CI .20-.97;≥60 kg/m2: OR .15, 95% CI .05-.42), number of co-morbidities (OR .83, 95% CI .74-.93), hypertension diagnosis (OR 2.42, 95% CI 1.42-4.13), prediet weight change (OR 1.08, 95% CI 1.01-1.16), and time between surgeon evaluation and preoperative LCD initiation (61-90 d: OR .46, 95% CI .23-.93). CONCLUSION Patients of female sex or non-Caucasian race; with a BMI≥50 kg/m2, many co-morbidities, or no hypertension diagnosis at surgeon evaluation; who demonstrate prediet weight loss or extended wait time between surgeon evaluation and preoperative LCD initiation may be at risk for preoperative weight loss failure and may require preemptive diet modification to improve outcomes.
