Impact of Preoperative Nutritional Support on Surgical Outcomes in Gastrointestinal Surgeries: A Systematic Review.

Malnutrition presents a significant risk to patients undergoing gastrointestinal surgery, with direct consequences on postoperative complication rates, recovery times, and mortality. Our systematic review, guided by PRISMA protocols, examined the impact of preoperative nutritional support on these surgical outcomes. We scrutinized publications from PubMed, Medline, Embase, and the Cochrane Library up to April 2023, including randomized controlled trials, cohort studies, and systematic reviews. The stringent selection process narrowed to 10 studies demonstrating the efficacy of preoperative nutritional support, from oral supplements to enteral and parenteral nutrition, in reducing postoperative complications and length of hospital stays while enhancing recovery rates. The benefits varied, indicating a pressing need for customized nutritional regimens based on patient demographics and surgical specifics. Our findings advocate incorporating individualized nutritional strategies into preoperative care, enhancing patient outcomes. Future research should aim to refine these strategies, focusing on the optimal timing, duration, and type of nutritional support.

The Difficulty of Detecting Occult Metastases in Patients with Potentially Resectable Pancreatic Cancer: Development and External Validation of a Preoperative Prediction Model.

Occult metastases are detected in 10-15% of patients during exploratory laparotomy for pancreatic cancer. This study developed and externally validated a model to predict occult metastases in patients with potentially resectable pancreatic cancer. Model development was performed within the Dutch Pancreatic Cancer Audit, including all patients operated for pancreatic cancer (January 2013-December 2017). Multivariable logistic regression analysis based on the Akaike Information Criteria was performed with intraoperative pathologically proven metastases as the outcome. The model was externally validated with a cohort from the University Hospital of Verona (January 2013-December 2017). For model development, 2262 patients were included of whom 235 (10%) had occult metastases, located in the liver (n = 143, 61%), peritoneum (n = 73, 31%), or both (n = 19, 8%). The model included age (OR 1.02, 95% CI 1.00-1.03), BMI (OR 0.96, 95% CI 0.93-0.99), preoperative nutritional support (OR 1.73, 95% CI 1.01-2.74), tumor diameter (OR 1.60, 95% CI 1.04-2.45), tumor composition (solid vs. cystic) (OR 2.33, 95% CI 1.20-4.35), and indeterminate lesions on preoperative imaging (OR 4.01, 95% CI 2.16-7.43). External validation showed poor discrimination with a C-statistic of 0.56. Although some predictor variables were significantly associated with occult metastases, the model performed insufficiently at external validation.

The impact of early nutritional support on postoperative wound healing in patients with complex fractures: A meta-analysis review.

Complex fractures present significant challenges in orthopaedic surgery, particularly in terms of postoperative wound healing. Nutritional status plays a crucial role in the recovery process, with early nutritional support potentially influencing wound healing outcomes. This meta-analysis aimed to assess the impact of early nutritional interventions on postoperative wound healing and scar formation in patients with complex fractures. From an initial pool of 1742 articles, 7 studies were selected for analysis. The results revealed that preoperative nutritional support significantly improved early wound healing, as indicated by lower REEDA scores (SMD = -14.06, 95% CI: [-16.79, -11.32], p < 0.01) 1 week post-surgery. Furthermore, there was a notable reduction in scar formation, as demonstrated by lower Manchester Scar Scale scores (SMD = -25.03, 95% CI: [-30.32, -19.74], p < 0.01) 3 months post-surgery. These findings highlight the importance of incorporating nutritional strategies into the management of complex fractures to optimize postoperative recovery.

Frequency and predictors of complication clustering within 30days of spinal fusion surgery: a study of children with neuromuscular scoliosis.

There is limited information on the clustering or co-occurrence of complications after spinal fusion surgery for neuromuscular disease in children. We aimed to identify the frequency and predictive factors of co-occurring perioperative complications in these children. In this retrospective database cohort study, we identified children (ages 10-18years) with neuromuscular scoliosis who underwent elective spinal fusion in 2012-2020 from the National Surgical Quality Improvement Program-Pediatric database. The rates of co-occurring complications within 30days were calculated, and associated factors were identified by logistic regression analysis. Correlation between a number of complications and outcomes was assessed. Approximately 11% (709/6677 children with neuromuscular scoliosis undergoing spinal fusion had co-occurring complications: 7% experienced two complications and 4% experienced ≥ 3. The most common complication was bleeding/transfusion (80%), which most frequently co-occurred with pneumonia (24%) and reintubation (18%). Surgical time ≥ 400min (odds ratio (OR) 1.49 [95% confidence interval (CI) 1.25-1.75]), fusion ≥ 13 levels (1.42 [1.13-1.79]), and pelvic fixation (OR 1.21 [1.01, 1.44]) were identified as procedural factors that independently predicted concurrent complications. Clinical risk factors for co-occurring complications included an American Society of Anesthesiologist physical status classification ≥ 3 (1.73 [1.27-2.37]), structural pulmonary/airway abnormalities (1.24 [1.01-1.52]), impaired cognitive status (1.80 [1.41-2.30]), seizure disorder (1.36 [1.12-1.67]), hematologic disorder (1.40 [1.03-1.91], preoperative nutritional support (1.34 [1.08-1.72]), and congenital malformations (1.20 [1.01-1.44]). Preoperative tracheostomy was protective against concurrent complications (0.62 [0.43-0.89]). Significant correlations were found between number of complications and length of stay, non-home discharge, readmissions, and death. Longer surgical time (≥ 400min), fusion ≥ 13 levels and pelvic fixation are surgical risk factors independently associated with co-occurring complications, which were associated with poorer patient outcomes. Recognizing identified nonmodifiable risk factors might also be important for preoperative planning and risk stratification of children with neuromuscular scoliosis requiring spinal fusion. Level IV evidence.

Lack of clinical benefit from preoperative short-term parenteral nutrition on the clinical prognosis of patients treated with radical gastrectomy for gastric cancer: a two-center retrospective study based on propensity score matching analysis.

Preoperative nutritional support studies for patients undergoing gastrointestinal (GI) surgery mostly focused on enteral nutrition (EN) or long-term (≥7 days) parenteral nutrition (PN). Some studies also found that preoperative short-term PN could improve the postoperative short-term nutritional status of tumor patients. But whether short-term PN support (1-6 days) before surgery can improve the prognosis of patients undergoing surgery for gastric cancer (GC) remains unclear. Therefore, we focused on assessing the effect of preoperative short-term PN on the outcomes of patients undergoing radical surgery for GC. A retrospective analysis of 1,155 patients who underwent radical gastrectomy for GC between July 2014 and February 2019 was conducted. According to whether patients received short-term (1-6 days) PN support before surgery, patients were divided into non-PN group and PN group. After 1:1 propensity score matching (PSM), two groups of patients with similar baseline clinical characteristics were obtained. The incidence of various complications and overall survival (OS) rate were compared between the two groups, and logistic regression analysis for complications, Cox regression analysis for OS, and subgroup analysis were performed. Each group had 478 patients after PSM, and the clinical characteristics were balanced. There were no significant differences in overall postoperative complications (pre-PSM: P=0.495; post-PSM: P>0.99), postoperative length of stay (LOS; pre-PSM: P=0.092; post-PSM: P=0.460), or readmission rate within 30 days (pre-PSM: P=0.496; post-PSM: P=0.793) between the two groups before and after PSM. The OS of PN group before matching was lower than that of non-PN group (P=0.023), but this difference was not significant after matching (P=0.950), but the PN group's hospitalization expenses were substantially greater than those of the control group (post-PSM: P<0.001). Preoperative short-term PN support was not an independent factor in the incidence of postoperative complications (P>0.99) and OS (P=0.949). Subgroup analyses failed to identify those patients who might benefit from preoperative short-term PN support. Preoperative short-term PN support may have no significant benefit on short-term postoperative complications or the long-term OS of patients with GC but increase hospitalization costs. It thus should not be the first choice of treatment for these patients.

A nomogram to predict stoma creation in elective surgical resection for penetrating Crohn's disease.

The decision to perform a stoma during surgical resection of penetrating Crohn's disease (CD) is a critical consideration. The objective of this study was to identify factors that influence stoma creation and develop a predictive nomogram model to assist surgeons in making optimal surgical decisions. A retrospective study was conducted at a tertiary center from December 1, 2012, to December 1, 2021, involving consecutive patients with penetrating CD who underwent elective surgical resection. The LASSO regression method was used to select preoperative predictors, and a nomogram was constructed using multivariate logistic regression. The performance of the nomogram was validated in an internal cohort by assessing its discrimination, calibration, and clinical usefulness. The study included 405 cases in the training group and 135 cases in the validation group. Nine risk factors for stoma formation were identified, including disease location, fistula resulted from previous anastomosis, absence of preoperative exclusive enteral nutrition support, albumin levels below 35 g/L, C-reactive protein levels above 10 mg/L, hemoglobin levels below 100 g/L, perianal disease, internal fistula, and surgical approach. These risk factors were selected using the LASSO regression method, and a nomogram was developed based on them. The area under the curve and the coefficient of determination (R2 ) of the nomogram were 0.821 and 0.394, respectively. And the nomogram demonstrated good performance in the validation cohort. The nomogram exhibited good predictive ability for stoma formation during elective surgical resection for penetrating CD, which can assist surgeons in making informed clinical decisions.

P564 Surgical treatment of jejuno-ileal Crohn’s disease. Results from the The JejUno Ileal Crohn's disEase (JUICE) international, multicentric, observational study

Abstract Background Crohn’s disease (CD) affecting the upper gastrointestinal (GI) tract is a rare condition, leading to a scarcity of information regarding its diagnosis, surgical treatment, and adjuvant therapy. The JUICE study aimed to conduct a surgical audit of duodeno-jejuno-ileal CD across 11 European IBD Referral Centres. Methods The study included all the consecutive, non-selected patients undergoing surgery for upper-GI CD between January 2010 and December 2022. Patients with synchronous ileal and colonic locations were included, while those with previous upper-GI CD surgery or multiple surgeries for ileo-colic CD were excluded. Univariate and multivariate analyses of 120 variables, covering pre-operative characteristics, intra-operative findings, and post-operative follow-up, were conducted. Results The study encompassed 279 patients, with a male/female ratio of 2.2. The average age at diagnosis was 30±14 years, and the disease duration was 11±10 years. The Montreal Classification revealed A1 15.4%, A2 61.3%, A3 23.3%; L1+L4 34.4%, L2+L4 4%, L3+L4 26.9%, isolated L4 34%; B1 1.8%, B2 67.4%, B3 30.8%; perianal location 19.4%. BMI averaged 21±3. Preoperative nutritional support was necessary in 50.5%. MRI-enterography was the predominant preoperative examination (86.7%). Comorbidities were present in 24.7%, with 61% having an ASA score &amp;gt;1. In the 30 days pre-surgery, 16.8% used steroids, 41.2% received biologicals, with 24.6% on combined (biologicals + steroids) therapy. Video-assisted approach was used in 70%, with a 5.1% conversion rate. Intraoperative staging revealed 1334 locations treated with 247 resections, 500 strictureplasties, 12 bypasses, and 53 concomitant colonic resections. Entero-enteric fistulas and intra-abdominal abscesses were present in 29% and 14%. Patients with thickened mesentery, wrapping fat, and lymph node enlargement were 50.8%, 38.7%, and 50.8%, respectively. Mortality was 1%, Clavien-Dindo grade 3 and 4 complication rate 11.1%. Hospital stay averaged 10±6 days; 90-day readmission was 3.2%. B3 behaviour, smoking, preoperative malnutrition, and preoperative biological therapy increased postoperative complication risk (p=0.01). 10-year Kaplan-Meier surgical recurrence rate was 23%, reduced to 11% with early and continuous post-op biologic treatment compared to late treatment or suspension (60% - Log-Rank p&amp;lt;0.0001). Conclusion This is by far the largest series of upper-GI CD ever studied, depicting a little known, complex, technically demanding sub-group of patients. Preoperative optimization, focusing on preoperative nutritional status and therapy, is crucial to reduce complication risk. Early-onset post-operative biological therapy seems to significantly reduce long-term surgical recurrence.

Preoperative Exclusive Enteral Nutrition Is Associated With Reduced Skin and Soft Tissue and Intra-abdominal Infections in Patients With Crohn's Disease Undergoing Intestinal Surgery: Results from a Meta-Analysis.

Malnutrition is an independent risk factor for adverse postoperative outcomes and is common among patients with Crohn's disease (CD). The objective of this meta-analysis was to precisely quantify the association of preoperative exclusive enteral nutrition (EEN) and total parenteral nutrition (TPN) with surgical outcomes in patients undergoing intestinal surgery for CD. PubMed, Embase, and Scopus were queried for comparative studies evaluating the impact of preoperative nutritional support on postoperative outcomes in patients undergoing surgery for CD. Random effects modeling was used to compute pooled estimates of risk difference. Heterogeneity was assessed using I2. Fourteen studies, all nonrandomized cohort studies, met inclusion criteria for studying EEN. After pooling data from 14 studies (874 EEN treated and 1044 control patients), the relative risk of intra-abdominal septic complications was decreased 2.1-fold in patients receiving preoperative EEN (relative risk 0.47, 95% confidence interval [CI], 0.35-0.63, I2 = 0.0%). After pooling data from 9 studies (638 EEN treated and 819 control patients), the risk of skin and soft tissue infection was decreased 1.6-fold (relative risk 0.63; 95% CI, 0.42-0.94, I2 = 42.7%). No significant differences were identified in duration of surgery, length of bowel resected, or operative blood loss. Among the 9 studies investigating TPN, no significant differences were identified in infectious outcomes. Preoperative nutritional optimization with EEN was associated with reduced risk of infectious complications in CD patients undergoing intestinal surgery. Preoperative nutritional support with EEN should be considered for optimizing outcomes in CD patients requiring bowel resection surgery.

Preoperative nutritional support in pancreatic cancer patients undergoing surgery and its effect on nutritional status: an observational multicenter network study investigating current best practice

Preoperative nutritional support in pancreatic cancer patients undergoing surgery and its effect on nutritional status: an observational multicenter network study investigating current best practice

Preoperative nutritional support in patients undergoing pancreatic surgery affects PREPARE score accuracy.

This study aimed to validate the accuracy of the Preoperative Pancreatic Resection (PREPARE) risk score in pancreatic resection patients. This prospective study included 216 patients who underwent pancreatic resection between January 2015 and December 2018. All patients in our cohort with weight loss or lack of appetite received dietary advice and preoperative oral nutritional supplementation (600 kcal/day). Demographic, clinicopathological, operative, and postoperative data were collected prospectively. The PREPARE score and the predicted risk of major complications were computed for each patient. Differences in major postoperative complications were analyzed using a multivariate Cox proportional hazards regression model. The predicted and observed risks of major complications were tested using the C-statistic. The study included 216 patients [117 men (54.2%)] with a median age of 65.0 (30.0-83.0) years. The majority of patients were classified as American Society of Anesthesiologists (ASA)' Physical Status score II (N = 164/216; 75.9%) and as "low risk" PREPARE score (N = 185/216; 85.6%) before the surgery. Only 4 (1.9%) patients were malnourished, with albumin levels of less than 3.5 g/dl. The most common type of pancreatic resection was a pylorus-preserving pancreaticoduodenectomy (N = 122/216; 56.5%). Major morbidity and 30-day mortality rates were 11.1% and 1.9%, respectively. The type of surgical procedure (hazard ratio [HR]: 3.849; 95% confidence interval [CI]: 1.208-12.264) and ASA score (HR: 3.089; 95% CI: 1.067-8.947) were significantly associated with the incidence of major postoperative complications in multivariate analysis. The receiver operating characteristic curve was 0.657 for incremental values and 0.559 for risk categories, indicating a weak predictive model. The results of the present study suggest that the PREPARE risk score has low accuracy in predicting the risk of major complications in patients with consistent preoperative nutritional support. This limits the use of PREPARE risk score in future preoperative clinical routines.

361. THE IMPACT OF A PROGRAM TO IMPROVE PREOPERATIVE NUTRITION AND REHABILITATION FOR ESOPHAGEAL CANCER PATIENTS

Abstract Background Improvement of the preoperative inflammation, nutrition, and other systemic conditions may reduce surgical complications and improve the prognosis of cancer. The usefulness of preoperative nutritional therapy and rehabilitation has recently been discussed. We created a novel program of preoperative rehabilitation and nutritional support to improve postoperative outcomes. We examined the nutritional status and blood electrolyte predisposition before and after this program. Methods Thirty five patients who underwent esophagectomy for esophageal cancer. These patients performed muscle strengthening exercise and received jelly beverage containing branched-chain amino acids immediately after rehabilitation and immune-modulating liquid diets for 7 consecutive days before surgery. Nutritional guidance was provided by a dietitian, who set a daily energy target of 30 kcal/kg and a protein target of 1.2 g/kg. Upper and lower limb strength training was performed with a physical therapist. Blood biochemical data on nutrition such as serum Alb, PreAlb, CRP, levels were compared after preoperative support. Results Thirty five patients who underwent esophagectomy for esophageal cancer in this period and evaluate their blood and serum samples. The average age of the patients was 66 years, 29 men and 6 women. Serum Alb level was 4.01 ± 0.4 g/dl before admission and 3.74 ± 0.35 g/dl the day before surgery (p = 0.04), and serum transthyretin level was unchanged from 28.9 ± 5.5 mg/dl to 26.1 ± 4.75 mg/dl. Serum CRP level tended to decrease from O.23 ± 0.528 mg/dl before admission to 0.14 ± 0.23 mg/dl the day before surgery. Other index of nutritional status did not change significantly before or after the program. Improvements in preoperative inflammation and nutrition are expected to decrease surgical complications and contribute to cancer prognosis. Our study and intervention in the present study may have decreased inflammation, although it was not a clear objective improvement in nutritional status. The short duration of the intervention may have prevented a significant difference. A less prolonged hospitalization is not realistic and the most effective nutritional rehabilitation intervention should be devised in the future.

FTP4.8 A survey on enhanced recovery after surgery (ERAS) in Pakistan

Abstract Introduction ERAS protocols are multimodal perioperative care pathways designed to achieve early recovery after surgical procedures by maintaining pre-operative organ function and reducing the stress response following surgery. Despite a significant body of evidence indicating that ERAS protocols lead to improved outcomes, implementation has been slow, and is not yet universal. The aim of this study was to evaluate current implementation of enhanced recovery protocols among Pakistani surgeons. Methods A survey questionnaire consisting of 23 items was created to assess current trends in perioperative management of patients undergoing major surgery, and to ascertain the extent to which ERAS is understood and implemented. Results The survey was answered by 100 individuals. 32 % of participants were familiar with ERAS protocols. All participants gave pre-operative counselling. 26% performed preoperative nutritional assessment with provision of pre-operative nutritional support in 24 % cases. Anaemia was managed in 84 % cases and smoking cessation done in 70 %. Patients were kept nil per oral for &amp;gt; 6 hrs in about 80 % cases. Antibiotic prophylaxis given in 94 % cases. Preoperative loading with carbohydrate drinks is carried out in only 2% of cases with 90 % being unfamiliar with the term; nasogastric tube done (58 %), transurethral drainage (42%). opioid analgesia use 54 % and multi modal analgesia used in only 32 %. Prophylaxis for postoperative nausea and vomiting (34%), VTE prophylaxis 26 %. Early mobilization (84%) and early feeding in only 32 % was performed. Conclusion An ERAS program requires a dedicated multidisciplinary team willing to abandon out-dated paradigms and embrace new ideas.

Frequency and predictors of concurrent complications in multi-suture release for syndromic craniosynostosis

PurposeUnderstanding the complication profile of craniosynostosis surgery is important, yet little is known about complication co-occurrence in syndromic children after multi-suture craniosynostosis surgery. We examined concurrent perioperative complications and predictive factors in this population.MethodsIn this retrospective cohort study, children with syndromic diagnoses and multi-suture involvement who underwent craniosynostosis surgery in 2012–2020 were identified from the National Surgical Quality Improvement Program-Pediatric database. The primary outcome was concurrent complications; factors associated with concurrent complications were identified. Correlations between complications and patient outcomes were assessed.ResultsAmong 5,848 children identified, 161 children (2.75%) had concurrent complications: 129 (2.21%) experienced two complications and 32 (0.55%) experienced ≥ 3. The most frequent complication was bleeding/transfusion (69.53%). The most common concurrent complications were transfusion/superficial infection (27.95%) and transfusion/deep incisional infection (13.04%) or transfusion/sepsis (13.04%). Two cardiac factors (major cardiac risk factors (odds ratio (OR) 3.50 [1.92–6.38]) and previous cardiac surgery (OR 4.87 [2.36–10.04])), two pulmonary factors (preoperative ventilator dependence (OR 3.27 [1.16–9.21]) and structural pulmonary/airway abnormalities (OR 2.89 [2.05–4.08])), and preoperative nutritional support (OR 4.05 [2.34–7.01]) were independently associated with concurrent complications. Children who received blood transfusion had higher odds of deep surgical site infection (OR 4.62 [1.08–19.73]; p = 0.04).ConclusionsOur results indicate that several cardiac and pulmonary risk factors, along with preoperative nutritional support, were independently associated with concurrent complications but procedural factors were not. This information can help inform presurgical counseling and preoperative risk stratification in this population.

Enhanced Recovery After Surgery (ERAS) Protocol in Geriatric Hip Fractures: An Observational Study.

Geriatric hip fractures are the new global pandemic. It is predicted to reach 7.3-21.3 million cases worldwide by 2050. Even with optimal care, geriatric patients suffer a higher morbidity and mortality rate when compared with the general populationand often demand expensive hospital aftercare. This study aims to assess the implications of the successful adoption of the enhanced recovery after surgery (ERAS) protocol in the management of geriatric hip fractures in an Indian facility. This is a retrospective study conducted in a tertiary care hospital in India and reported following REporting of studies Conducted using the Observational Routinely collected health Data (RECORD) guidelines.We included all geriatric patients over 60 years of age who were admitted with hip fractures for surgical management between January 2021 and January 2023. The individual perioperative components of the ERAS protocol focus on key areas such as preoperative nutritional support, effective multimodal analgesia with optimal pain control, fluid management, and early postoperative mobilization. Thirty-eight geriatric patients with a mean age of 77.5 (± 9.6) years were included for analysis. Twenty-three patients sustained intertrochanteric fractures and underwent fixation with proximal femur nailing and the remaining had 15 sustained neck or femur fractures of which 11 underwent hemiarthroplasty surgery and the remaining four underwent a total hip replacement. The mean time to surgery was 2 (± 0.2) days. Eighty-two percent (n=31) of the patients were mobilized with a walking frame within a day after surgery and were followed up after discharge with home physiotherapy. The mean time to ambulation was 2 (± 0.62) days. The mean length of stay was 4 (± 1.6) days. We had a 30-day readmission rate of 5.2% (n=2) and a 30-day mortality rate of 5.2% (n=2). The one-year mortality rate was 13% (n=5). Management of geriatric hip fractures requires exceptional interdisciplinary coordination and carefully planned strategies to optimize patient care.With the implementation of the ERAS protocol, we could perceive clinical benefits in terms of early recovery and short length of hospital stay in patients with hip fractures. Further comparative studies are required, which can determine the relative importance of individual measures in the ERAS protocol and understand their longer-term outcomes in hip fracture surgeries.

Preoperative nutritional management - compliance with current guidelines.

Major surgery poses a significant stress to the patient. The nutritional status is one of crucial factors that have a substantial impact on the final outcome of the surgery. Preoperatively established malnutrition or an increased nutritional risk in this group of patients requires a maximum effort to minimize this negative impact as soon as the operation is scheduled. The aim of this retrospective study was to assess compliance with guidelines focused on preoperative nutrition management at our site. Our retrospective descriptive observation was focused on the period from January 1, 2017 to June 30, 2020. All patients scheduled for major surgery were screened for nutritional status using a nutritional questionnaire, and an appropriate type of nutritional intervention was indicated based on the achieved score. Two hundred and forty gastrointestinal operations were performed during the study period. In total, 208 (87%) of patients were screened at the time of counselling. Diet adjustments with an increased protein intake were recommended to all 125 (100%) patients with normal nutrition status. In total, 95 patients were at nutritional risk and sipping was prescribed to all of them (100%) in the outpatient setting. All 20 malnourished patients (100%) underwent preoperative nutritional optimization as inpatients. Nutritional status of patients before major surgery is considered a predictive indicator of potential postoperative complications. Compliance with recent ERAS guidelines concerning preoperative screening and nutritional support is high in our department.

Systematic review of preoperative n-3 fatty acids in major gastrointestinal surgery

ObjectivesPerioperative nutrition aims to replenish nutritional stores before surgery and reduce postoperative complications. ‘Immunonutrition’ (including omega-3 fatty acids) may modulate the immune system and attenuate the postoperative inflammatory response. Hitherto,...

Predicting surgical outcome and sagittal alignment change in patients with cervical spondylosis and degenerative kyphosis after anterior cervical discectomy and fusion

The aim of this study was to forecast the risk factors of poor outcomes and postoperative loss of lordosis or recurrence of kyphosis. In this retrospective study, 101 patients with cervical spondylosis and preoperative kyphosis who underwent anterior cervical discectomy and fusion (ACDF) were enrolled, between June 2015 and June 2019. Patients were grouped according to the recovery rate of Japanese Orthopaedic Association (JOA) score whether more than 50%, and the change of postoperative cervical Cobb angle. There were 22 cases with less than 50% of recovery rate and 35 cases with the worsening of postoperative sagittal alignment (WPSA). Multivariate linear-regression analysis was conducted with the data. Advanced age (p = 0.019), longer duration of symptoms (p = 0.003) and loss of local Cobb angle (LCA) after surgery (p = 0.031) was significantly associated with a poor clinical outcome. A whole kyphosis (p = 0.009), aggravated neck pain after surgery (p = 0.012), preoperative lower thoracic 1 (T1) (p < 0.001), bigger change of C2-7 sagittal vertical axis (SVA) (p = 0.008) and adjacent segment degeneration (ASD) (p = 0.024) was significantly associated with the WPSA. Preoperative health education, nutritional support and early postoperative rehabilitation intervention, in perioperative period, were recommended for patients with advance age, longer duration of symptoms, whole cervical kyphosis and lower T1. Postoperative sagittal malalignment was related to neck pain and ASD after surgery.

Creating the optimal preoperative nutritional status for neonates undergoing cardiac surgery by implementing a preoperative nutritional support plan.

The purpose of this study was to explore the effect of a preoperative nutritional support programme on improving preoperative nutritional status and promoting postoperative recovery in neonates undergoing cardiac surgery. The clinical data of neonates undergoing cardiac surgery who received preoperative nutritional support therapy in our hospital from March 2021 to December 2021 were collected, and the clinical data of neonates undergoing cardiac surgery who did not receive preoperative nutritional support therapy in our hospital from February 2020 to February 2021 were selected as the control. The nutritional status and postoperative recovery of the two groups were compared. A total of 30 neonates who received nutritional support before cardiac surgery were included in this study. A total of 28 neonates who did not receive nutritional support before cardiac surgery were included in the control group. There were no significant differences in general information or the nutritional status at birth between the two groups. The duration of nutritional support in the intervention group was 16.8 ± 7.1 days. Before the operation, the intervention group was significantly better than the control group in terms of body weight, albumin, prealbumin and haemoglobin, which indicated that the nutritional status of the intervention group was better than that of the control group. The intensive care time, ventilator time and hospital stay time in the intervention group were significantly lower than those in the control group. Nutritional support plans after birth for neonates with severe congenital heart disease can effectively improve the nutritional status of patients before surgery and accelerate the speed of postoperative recovery.

Con: Can We Influence Postoperative Outcomes of Frail Patients After Cardiac Surgery?

Frail patients are scheduled routinely for elective cardiovascular surgery. Despite the proven association between frailty and postoperative outcomes, currently, there is no consistent evidence that the preoperative optimization of frail patients with preoperative nutrition support and exercise programs can alter postoperative mortality. Established frailty diagnostic tools are not sufficient to grasp the multidimensional nature of frailty in cardiovascular patients. Prehabilitation programs and preoperative nutritional support are time- and resource-consuming and, therefore, are hard to implement in routine clinical practice.

Role of perioperative nutritional status and enteral nutrition in predicting and preventing post-operative complications in patients with Crohn's disease.

Perioperative immune-nutritional status is correlated with post-operative outcomes. This study aimed to evaluate whether pre-operative nutritional status could predict post-operative complications in patients with Crohn's disease (CD) and whether pre-operative enteral nutrition (EN) can prevent post-operative complications. This retrospective cohort study analyzed the electronic health records of 173 patients diagnosed with CD in Ruijin Hospital, Shanghai, China, between August 2015 and May 2021: 122 patients had pre-operative nutritional support while 51 patients underwent surgery without pre-operative nutritional support. The pre-operative nutritional status, disease activity index, disease-related data, frequency of multiple surgery, operative data, and post-operative characters in each group were compared to determine whether the nutritional support and status could significantly affect post-operative outcome. One-to-one propensity score matching (PSM) was performed to limit demographic inequalities between the two groups. After PSM, no statistically significant differences were found in pre-operative patient basic characteristics between the two groups of 47 patients (98 patients in all) included in this study. Overall, 21 patients developed 26 post-operative complications. In terms of pre-operative nutritional status, the level of serum albumin (ALB), pre-albumin (pre-ALB), and hemoglobin (Hb) in the nutrition group were statistically higher than that in the control group. We also observed a statistically significant decrease in post-operative complications, need for emergency surgery, and staged operations, while the rate of laparoscopic surgery was higher in the nutrition group compared to the non-nutritional group.
