Early versus traditional postoperative feeding in patients undergoing resectional gastrointestinal surgery: a meta-analysis

Comparison of Early Oral Feeding With Traditional Oral Feeding After Total Gastrectomy for Gastric Cancer: A Propensity Score Matching Analysis

Background: The present study aimed to compare the feasibility and safety of early oral feeding (EOF) with traditional oral feeding (TOF) after radical total gastrectomy for gastric cancer.

Methods: This retrospective study included consecutive patients who underwent total gastrectomy from April 2016 and November 2018. These patients were divided into two groups, according to their postoperative feeding protocol: EOF group (n = 314) and TOF group (n = 433). Propensity score matching was used to balance the potential confounders, and 276 patients were selected from each group. The EOF group received oral diet on postoperative day one, while the TOF group were started on oral feeding after the passage of flatus.

Results: No significant differences were found in the postoperative complications (P = 0.426) and tolerance to oral feeding (P > 0.056) between the two groups. The changes in perioperative nutritional markers were also similar between the two groups (P > 0.05). The time to first passage of flatus or defecation (47.19 ± 12.00 h vs. 58.19 ± 9.89 h, P < 0.0001) and length of postoperative hospital stay (6.84 ± 2.31 days vs. 7.72 ± 2.86 days, P < 0.0001) were significantly lower in the EOF group compared to the TOF group.

Conclusion: EOF may be safe and feasible after radical total gastrectomy with faster recovery and no increased risk of postoperative complications.

The malnourished surgery patient: a silent epidemic in perioperative outcomes?

PURPOSE OF REVIEW

As many as two of every three major surgery patients are malnourished preoperatively - a diagnosis rarely made and treated even less frequently. Unfortunately, perioperative malnutrition is perhaps the least often identified surgical risk factor and is among the most treatable to improve outcomes.

RECENT FINDINGS

Two important perioperative nutrition guidelines were published recently. Both emphasize nutrition assessment as an essential component of preoperative screening. The recently published perioperative nutrition screen (PONS) readily identifies patients at malnutrition risk, allowing for preoperative nutritional optimization. The use of computerized tomography scan and ultrasound lean body mass (LBM) evaluation to identify sarcopenia associated with surgical risk and guide nutrition intervention is garnering further support. Preoperative nutrition optimization in malnourished patients, use of immunonutrition in all major surgery, avoidance of preoperative fasting, inclusion of postoperative high-protein nutritional supplements, and early postoperative oral intake have all recently been shown to improve outcomes and should be utilized.

SUMMARY

The recent publication of new surgical nutrition guidelines, the PONS score, and use of LBM assessments will allow better identification and earlier intervention on perioperative malnutrition. It is essential that in the future no patient undergoes elective surgery without nutrition screening and nutrition intervention when malnutrition risk is identified.

The effect of diets delivered into the gastrointestinal tract on gut motility after colorectal surgery-a systematic review and meta-analysis of randomised controlled trials

BACKGROUND/OBJECTIVES

Despite best practice guidelines, feeding methods after colorectal surgery vary due to the difficulties translating evidence into practice. The aim was to determine the effectiveness of diets delivered into the gastrointestinal tract (GIT) on gut motility following colorectal surgery.

SUBJECTS/METHODS

EMBASE, MEDLINE, CINAHL, Web of Science and PubMed were systematically searched. Randomised controlled trials investigating effectiveness of a diet on gut motility after colorectal surgeries were included. Outcomes included postoperative ileus, length of stay, mortality, nausea and vomiting.

RESULTS

A total of 756 potential studies were identified; of these, 10 trials reporting on 1237 unique patients were included. There is evidence that early feeding reduces time (days) to first flatus (mean difference (MD):-0.64; 95% CI:-0.84 to -0.44) and bowel movements (MD:-0.64; 95% CI:-1.01 to -0.26), when compared to traditional postoperative fasting. Introducing solids versus the progression of fluids to solids had no effect on time (days) to first flatus (MD:0.13; 95% CI:-1.99 to 1.74) or bowel movement (MD:0.20; 95% CI:-0.50 to 0.98). Complete nutrition compared to hypocaloric nutrition had no effect on time to first flatus (MD:-0.60; 95% CI:-1.66 to 0.46) or bowel movement (MD:-0.20; 95% CI:-1.59 to 1.19), whereas coffee and diet compared to water and diet significantly decreased time (days) to first bowel movement (MD:-0.60; 95% CI:-0.97 to -0.19) but had no effect on time to first flatus (MD:-0.20; 95% CI:-0.57 to 0.09).

CONCLUSIONS

Any form of early postoperative diet provided into the GIT early after colorectal surgery is likely to stimulate gut motility, resulting in earlier return of bowel function and shorter length of stay.

American Society for Enhanced Recovery and Perioperative Quality Initiative Joint Consensus Statement on Nutrition Screening and Therapy Within a Surgical Enhanced Recovery Pathway

Perioperative malnutrition has proven to be challenging to define, diagnose, and treat. Despite these challenges, it is well known that suboptimal nutritional status is a strong independent predictor of poor postoperative outcomes. Although perioperative caregivers consistently express recognition of the importance of nutrition screening and optimization in the perioperative period, implementation of evidence-based perioperative nutrition guidelines and pathways in the United States has been quite limited and needs to be addressed in surgery-focused recommendations. The second Perioperative Quality Initiative brought together a group of international experts with the objective of providing consensus recommendations on this important topic with the goal of (1) developing guidelines for screening of nutritional status to identify patients at risk for adverse outcomes due to malnutrition; (2) address optimal methods of providing nutritional support and optimizing nutrition status preoperatively; and (3) identifying when and how to optimize nutrition delivery in the postoperative period. Discussion led to strong recommendations for implementation of routine preoperative nutrition screening to identify patients in need of preoperative nutrition optimization. Postoperatively, nutrition delivery should be restarted immediately after surgery. The key role of oral nutrition supplements, enteral nutrition, and parenteral nutrition (implemented in that order) in most perioperative patients was advocated for with protein delivery being more important than total calorie delivery. Finally, the role of often-inadequate nutrition intake in the posthospital setting was discussed, and the role of postdischarge oral nutrition supplements was emphasized.

Early enteral nutrition within 24 hours of lower gastrointestinal surgery versus later commencement for length of hospital stay and postoperative complications

BACKGROUND

This is an update of the review last published in 2011. It focuses on early postoperative enteral nutrition after lower gastrointestinal surgery. Traditional management consisted of 'nil by mouth', where patients receive fluids followed by solids after bowel function has returned. Although several trials have reported lower incidence of infectious complications and faster wound healing upon early feeding, other trials have shown no effect. The immediate advantage of energy intake (carbohydrates, protein or fat) could enhance recovery with fewer complications, and this warrants a systematic evaluation.

OBJECTIVES

To evaluate whether early commencement of postoperative enteral nutrition (within 24 hours), oral intake and any kind of tube feeding (gastric, duodenal or jejunal), compared with traditional management (delayed nutritional supply) is associated with a shorter length of hospital stay (LoS), fewer complications, mortality and adverse events in patients undergoing lower gastrointestinal surgery (distal to the ligament of Treitz).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Library 2017, issue 10), Ovid MEDLINE (1950 to 15 November 2017), Ovid Embase (1974 to 15 November 2017). We also searched for ongoing trials in ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform (15 November 2017). We handsearched reference lists of identified studies and previous systematic reviews.

SELECTION CRITERIA

We included randomised controlled trials (RCT) comparing early commencement of enteral nutrition (within 24 hours) with no feeding in adult participants undergoing lower gastrointestinal surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study quality using the Cochrane 'Risk of bias' tool tailored to this review and extracted data. Data analyses were conducted according to the Cochrane recommendations.We rated the quality of evidence according to GRADE.Primary outcomes were LoS and postoperative complications (wound infections, intraabdominal abscesses, anastomotic dehiscence, pneumonia).Secondary outcomes were: mortality, adverse events (nausea, vomiting), and quality of life (QoL).LoS was estimated using mean difference (MD (presented as mean +/- SD). For other outcomes we estimated the common risk ratio (RR) and calculated the associated 95% confidence intervals. For analysis, we used an inverse-variance random-effects model for the primary outcome (LoS) and Mantel-Haenszel random-effects models for the secondary outcomes. We also performed Trial Sequential Analyses (TSA).

MAIN RESULTS

We identified 17 RCTs with 1437 participants undergoing lower gastrointestinal surgery. Most studies were at high or unclear risk of bias in two or more domains. Six studies were judged as having low risk of selection bias for random sequence generation and insufficient details were provided for judgement on allocation concealment in all 17 studies. With regards to performance and deception bias; 14 studies reported no attempt to blind participants and blinding of personnel was not discussed either. Only one study was judged as low risk of bias for blinding of outcome assessor. With regards to incomplete outcome data, three studies were judged to be at high risk because they had more than 10% difference in missing data between groups. For selective reporting, nine studies were judged as unclear as protocols were not provided and eight studies had issues with either missing data or incomplete reporting of results.LOS was reported in 16 studies (1346 participants). The mean LoS ranged from four days to 16 days in the early feeding groups and from 6.6 days to 23.5 days in the control groups. Mean difference (MD) in LoS was 1.95 (95% CI, -2.99 to -0.91, P < 0.001) days shorter in the early feeding group. However, there was substantial heterogeneity between included studies (I² = 81, %, Chi² = 78.98, P < 0.00001), thus the overall quality of evidence for LoS is low. These results were confirmed by the TSA showing that the cumulative Z-curve crossed the trial sequential monitoring boundary for benefit.We found no differences in the incidence of postoperative complications: wound infection (12 studies, 1181 participants, RR 0.99, 95%CI 0.64 to 1.52, very low-quality evidence), intraabdominal abscesses (6 studies, 554 participants, RR 1.00, 95%CI 0.26 to 3.80, low-quality evidence), anastomotic leakage/dehiscence (13 studies, 1232 participants, RR 0.78, 95%CI 0.38 to 1.61, low-quality evidence; number needed to treat for an additional beneficial outcome (NNTB) = 100), and pneumonia (10 studies, 954 participants, RR 0.88, 95%CI 0.32 to 2.42, low-quality evidence; NNTB = 333).Mortality was reported in 12 studies (1179 participants), and showed no between-group differences (RR = 0.56, 95%CI, 0.21 to 1.52, P = 0.26, I² = 0%, Chi² = 3.08, P = 0.96, low-quality evidence). The most commonly reported cause of death was anastomotic leakage, sepsis and acute myocardial infarction.Seven studies (613 participants) reported vomiting (RR 1.23, 95%CI, 0.96 to 1.58, P = 0.10, I² = 0%, Chi² = 4.98, P = 0.55, low-quality evidence; number needed to treat for an additional harmful outcome (NNTH) = 19), and two studies (118 participants) reported nausea (RR 0.95, 0.71 to 1.26, low-quality evidence). Four studies reported combined nausea and vomiting (RR 0.94, 95%CI 0.51 to 1.74, very low-quality evidence). One study reported QoL assessment; the scores did not differ between groups at 30 days after discharge on either QoL scale EORTC QLQ-C30 or EORTC QlQ-OV28 (very low-quality evidence).

AUTHORS' CONCLUSIONS

This review suggests that early enteral feeding may lead to a reduced postoperative LoS, however cautious interpretation must be taken due to substantial heterogeneity and low-quality evidence. For all other outcomes (postoperative complications, mortality, adverse events, and QoL) the findings are inconclusive, and further trials are justified to enhance the understanding of early feeding for these. In this updated review, only a few additional studies have been included, and these were small and of poor quality.To improve the evidence, future trials should address quality issues and focus on clearly defining and measuring postoperative complications to allow for better comparison between studies. However due to the introduction of fast track protocols which already include an early feeding component, future trials may be challenging. A more feasible trial may be to investigate the effect of differing postoperative energy intake regimens on relevant outcomes.

Multimodal Nutritional Management in Primary Lumbar Spine Surgery: A Randomized Controlled Trial

STUDY DESIGN

A prospective randomized controlled trial.

OBJECTIVE

The purpose of this study was to evaluate the clinical effect and safety of a new multimodal nutritional management (MNM) protocol for patients receiving primary lumbar spine surgery.

SUMMARY OF BACKGROUND DATA

Poor nutritional status is common in the perioperative period in primary lumbar spine surgery, and may impede recovery after surgery.

METHODS

A total of 187 patients were included in this prospective randomized controlled trial. They were randomly assigned to the MNM group or the control group. Albumin (ALB) infusion, postoperative ALB level, electrolyte disorders, postoperative electrolyte levels, transfusion rate, postoperative hemoglobin level, length of stay (LOS), and complications were compared between the groups.

RESULTS

Compared with the control group, the rate and the total amount of ALB infusion were lower in the MNM group, and the postoperative level of ALB in the MNM group was higher on the first postoperative day, and the third postoperative day. The incidence of hypokalemia, hyponatremia, and hypocalcemia were lower in the MNM group. In the MNM group, the postoperative levels of sodium, potassium, and calcium were higher than the control group. The transfusion rate was similar between the two groups. The hemoglobin level was similar between the two groups on first postoperative day, but was higher in the MNM group on third postoperative day. LOS in the MNM group was shorter than in the control group. The incidence of wound drainage was lower in the MNM group. No statistical differences were observed regarding surgical complications between the two groups.

CONCLUSION

The MNM protocol effectively reduced ALB infusion, the incidence of electrolyte disorders, and wound drainage, increased the postoperative levels of ALB, sodium, potassium, and calcium, and reduced the LOS without increasing the rate of postoperative complications.

Enteral versus parenteral nutrition following pancreaticoduodenectomy: a systematic review and meta-analysis

BACKGROUND

The need for nutritional support following pancreaticoduodenectomy is well recognised due to the high prevalence of malnutrition, but the optimal delivery route is still debated. This meta-analysis evaluated postoperative outcomes in patients receiving enteral or parenteral nutrition.

METHODS

EMBASE, MEDLINE and Cochrane databases were searched to identify randomised controlled trials comparing enteral and parenteral nutrition in patients undergoing pancreaticoduodenectomy. The primary outcome measure was delayed gastric emptying (DGE). Secondary outcome measures included length of hospital stay (LOS); postoperative pancreatic fistula (POPF); post-pancreaticoduodenectomy haemorrhage (PPH); and infective complications (IC).

RESULTS

Five randomised controlled trials met inclusion criteria and reported on 690 patients (enteral nutrition n = 383; and parenteral nutrition n = 307). Median age was 61.5 years (interquartile range 60.1-63.6). The pooled relative risk (RR) of the primary outcome, DGE, was 0.97 (95% confidence interval (CI) 0.52-1.81, p = 0.93). There were no statistically significant difference in the secondary outcome measures of POPF (RR 1.07, 95% CI 0.42-2.76, p = 0.88); PPH (RR 0.67, 95% CI 0.31-1.48, p = 0.33) and infectious complications (RR 0.76, 95% CI 0.50-1.17, p = 0.22). However, LOS favoured enteral nutrition, weighted mean difference -1.63 days (95% CI -2.80, -0.46, p = 0.006).

CONCLUSIONS

EN is associated with a significantly shorter LOS compared to PN in patients undergoing pancreaticoduodenectomy.

Diet and inflammatory bowel disease: The Asian Working Group guidelines

INTRODUCTION

These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries.

METHODOLOGY

The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required.

RESULTS

Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation.

CONCLUSIONS

Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.

Hospital Staffs' Perceptions of Postoperative Nutrition Among Colorectal Patients: A Qualitative Study

BACKGROUND

After lower gastrointestinal surgery, few patients start eating within timeframes outlined by evidence-based guidelines or meet their nutrition requirements in hospital. The present study explored hospital staffs' perceptions of factors influencing timely and adequate feeding after colorectal surgery to inform future interventions for improving postoperative nutrition practices and intakes.

METHODS

This qualitative exploratory study was conducted at an Australian hospital where Enhanced Recovery After Surgery guidelines had not been formally implemented. One-on-one semistructured interviews were conducted with hospital staff who provided care to patients undergoing colorectal surgery. Interviews lasted from 21 to 47 minutes and were audio recorded and transcribed verbatim. Data were analyzed using inductive thematic analysis. Emergent themes and subthemes were discussed by all investigators to ensure consensus of interpretation.

RESULTS

Eighteen staff participated in interviews, including 9 doctors, 5 nurses, 2 dietitians, and 2 foodservice staff. Staffs' responses formed 3 themes: (1) variability in perceived acceptability of postoperative feeding; (2) improving dynamics and communication within the treating team; and (3) optimizing dietary intakes with available resources.

CONCLUSION

Staff and organizational factors need to be considered when attempting to improve postoperative nutrition among patients who undergo colorectal surgery. Introducing a feeding protocol, enhancing intraprofessional and interdisciplinary communication, and ensuring the availability of appropriate, nutrient-dense foods are pivotal to improve nutrition practices and intakes.

Effect of early enteral nutrition on laparoscopic common bile duct exploration with enhanced recovery after surgery protocols

BACKGROUND/OBJECTIVES

Protocols for enhanced recovery after surgery (ERAS) provide comprehensive and evidence-based guidelines to improve perioperative care. It remains elusive whether early enteral nutrition (EEN) will play an active role in the ERAS protocols. Laparoscopic common bile duct exploration (LCBDE) is a safe and efficient method to treat patients with bile duct stones. This study aims to assess the safety, tolerability, and outcomes of EEN after LCBDE.

SUBJECTS /METHODS

From January 2014 to April 2017, a total of 100 patients with postoperative LCBDE were chosen and randomly divided into control group and EEN group. Patients in the control group were treated with traditional management with regular diet when tolerated, while patients in the EEN group were fed with EEN 3 h after LCBDE. The patients' characteristics, time to first flatus, complications, hospitalization stay, and hospitalization expenses were assessed and compared between patients in these two groups.

RESULTS

EEN accelerated the recovery of gastrointestinal function, being indicated by reduced time to first flatus when compared with control group (P = 0.00). In accordance, the quick recovery of gastrointestinal function resulted in shorter hospitalization stay for the EEN group (P = 0.00); however, no significant difference was shown when comparing the hospitalization expenses. On another hand, early oral feeding increased the occurrence of abdominal distension and diarrhea complications (P = 0.00 and P = 0.03).

CONCLUSIONS

EEN effectively improves gastrointestinal function, but raises complications such as abdominal distension and diarrhea after LCBDE. It is recommended to implement the EEN as early as possible if the patients are reasonably expected to have high compliance.

A Meta-Analysis and Systematic Review of Perioperative Outcomes of Laparoscopic-assisted Rectal Resection (LARR) Versus Open Rectal Resection (ORR) for Carcinoma

AIMS AND OBJECTIVES

The aim was to conduct a systematic review and meta-analysis of the randomized evidence to determine the relative merits of perioperative outcomes of laparoscopic-assisted (LARR) versus open rectal resection (ORR) for proven rectal cancer.

MATERIALS AND METHODS

A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified English-language randomized clinical trials comparing LARR and ORR. The meta-analysis was prepared in accordance with the PRISMA statement. Thirteen outcome variables were analyzed. Random effects meta-analyses were performed due to heterogeneity.

RESULTS

A total of 14 randomized clinical trials that included 3843 rectal resections (LARR 2096, ORR 1747) were analyzed. The summary point estimates favored LARR for the intraoperative blood loss, commencement of oral intake, first bowel movement, and length of hospital stay. There was significantly longer duration of operating time of 38.29 minutes for the LARR group. Other outcome variables such as total complications, postoperative pain, postoperative ileus, abdominal abscesses, postoperative anastomotic leak, reintervention and postoperative mortality rates were found to have comparable outcomes for both cohorts.

CONCLUSIONS

LARR was associated with significantly reduced blood loss, quicker resumption of oral intake, earlier return of gastrointestinal function, and shorter length of hospital stay at the expense of significantly longer operating time. Postoperative morbidity and mortality and analgesia requirement for both these groups were comparable. LARR seems to be a safe and effective alternative to ORR; however, it needs to be performed in established colorectal units with experienced laparoscopic surgeons.

Jejunostomy or nasojejunal tube after esophagectomy: a review of the literature

Patients undergoing esophagectomy for cancer are a difficult to treat group of patients. At diagnosis they will present some degree of malnutrition in up to 80% and the causes are from multifactorial origin: the inability of food ingestion, advanced age, taste disturbances, and morbidity related to neoadjuvant treatment. In order to restaure the nutritional status, enteral nutritional support is preferable to parenteral support because of the risks of septic complications associated with venous catheters. During the postoperative period, the oral route is often inaccessible in these patients due to swallowing disorders and eventually mechanical ventilation, and if possible, often it does not provide sufficient caloric amounts for postoperative energy balance. For these reasons, it is usually recommended additional nutritional support. There are few studies in the literature that specifically address which is the most adequate route for enteral nutrition in patients undergoing esophagectomy. Nasojejunal catheters present a higher incidence of local complications, such as displacement and occlusion, whereas jejunostomy is more associated with reinterventions for the treatment of complications secondary to extravasation. Although there is weak evidence in the literature and a lack of randomized, prospective and multicenter studies evaluating the best enteral nutrition route in the postoperative period of esophagectomy, the use of the nasoenteric catheter seems to be adequate due to its simplicity of positioning and low rates of severe complications. In this paper a review is performed of the evidence about this subject.

Prehabilitation for esophagectomy

Esophagectomy remains the mainstay treatment of esophageal cancer (EC). Combined with neoadjuvant therapies, the management of EC has deleterious effects on body composition, functional capacity and psychological well-being. Preoperative patient optimisation known as prehabilitation is a novel intervention aimed at reducing morbidity and mortality associated with the trajectory of EC care. There is emerging evidence to suggest that prehabilitation is safe, feasible and efficacious. In addition, there is strong data to infer that prehabilitation has a positive effect on functional capacity through exercise. Nutritional and psychological interventions are less well evaluated. Furthermore, no convincing relationship between prehabilitation and oncological outcomes has been demonstrated. Early studies evaluating prehabilitation are promising however further large scale research is required in order to assess the clinical effectiveness.

A qualitative exploration of factors influencing medical staffs' decision-making around nutrition prescription after colorectal surgery

BACKGROUND

Enhanced Recovery After Surgery (ERAS) guidelines recommend early oral feeding with nutritionally adequate diets after surgery. However, studies have demonstrated variations in practice and poor adherence to these recommendations among patients who have undergone colorectal surgery. Given doctors are responsible for prescribing patients' diets after surgery, this study explored factors which influenced medical staffs' decision-making regarding postoperative nutrition prescription to identify potential behaviour change interventions.

METHODS

This qualitative study involved one-on-one, semi-structured interviews with medical staff involved in prescribing nutrition for patients following colorectal surgery across two tertiary teaching hospitals. Purposive sampling was used to recruit participants with varying years of clinical experience. The Theoretical Domains Framework (TDF) underpinned the development of a semi-structured interview guide. Interviews were audio recorded, with data transcribed verbatim before being thematically analysed. Emergent themes and sub-themes were discussed by all investigators to ensure consensus of interpretation.

RESULTS

Twenty-one medical staff were interviewed, including nine consultants, three fellows, four surgical trainees and five junior medical doctors. Three overarching themes emerged from the data: (i) Prescription preferences are influenced by perceptions, experience and training; (ii) Modifying prescription practices to align with patient-related factors; and (iii) Peers influence prescription behaviours and attitudes towards nutrition.

CONCLUSIONS

Individual beliefs, patient-related factors and the social influence of peers (particularly seniors) appeared to strongly influence medical staffs' decision-making regarding postoperative nutrition prescription. As such, a multi-faceted approach to behaviour change is required to target individual and organisational barriers to enacting evidence-based feeding recommendations.

Optimizing health before elective thoracic surgery: systematic review of modifiable risk factors and opportunities for health services research

Despite progress in many different domains of surgical care, we are still striving toward practices which will consistently lead to the best care for an increasingly complex surgical population. Thoracic surgical patients, as a group, have multiple medical co-morbidities and are at increased risk for developing complications after surgical intervention. Our healthcare systems have been focused on treating complications as they occur in the hopes of minimizing their impact, as well as aiding in recovery. In recent years there has emerged a body of evidence outlining opportunities to optimize patients and likely prevent or decrease the impact of many complications. The purpose of this review article is to summarize four major domains-optimal pain control, nutritional status, functional fitness, and smoking cessation-all of which can have a substantial impact on the thoracic surgical patient's course in the hospital-as well as to describe opportunities for improvement, and areas for future research efforts.

Early oral feeding versus traditional feeding after transanal endorectal pull-through procedure in Hirschsprung's disease

Our study questioned whether the outcome of postoperative early oral feeding is different from traditional postoperative feeding in children with Hirschsprung's disease who underwent transanal endorectal pull-through.This was an observational and comparative study. Patients were allocated into 2 groups. Age, gender, fever, surgery-related infectious, abdominal distension, bowel obstruction, need for reoperation, peritonitis, anastomosis leak, and abscess formation were assessed. IV fluids and antibiotics usage were recorded. A Chi-square test, independent sample unpaired Student t test and Mann-Whitney test were used. P-value < .05 was considered statistically significant.Infections occurred in no patient in group 1 and 1 patient in group 2. Stenosis occurred in 3 patients in group 1 and 2 patients in group 2. Abdominal distension occurred in 4 patients in group 1 and 3 patients in group 2. Fever occurred in 2 patients in group 1 and 1 patient in group 2 within the first 24 hours and it occurred in 13 and 17 patients, respectively, within 48 hours. All patients of group 1 (n = 15) were treated with antibiotics and intravenous fluid administration; 1 patient for 24 hours, 12 patients for 48 hours, and 1 for 72 hours, respectively. All patients of group 2 (n = 18) were treated with antibiotics and intravenous fluid administration for 5 days. We noted a significant difference regarding the duration of antibiotic treatment and intravenous fluid administration after 72 hours.This study showed that there was no difference between the outcomes of early and traditional postoperative feeding. Due to a significant difference in the antibiotics and IV fluid administration intervals between these 2 groups which cause a prolonged hospital stay and higher costs, it seems that early postoperative feeding is superior to traditional strategy.

Risk factors for early postoperative cognitive dysfunction after colorectal surgery

Background

It has been reported that postoperative cognitive dysfunction (POCD) is correlated with the degeneration of the central nervous system, oxidative stress, inflammation, and endocrine and immune dysfunction. Increased age, predisposed comorbidity, long surgery time, and prolonged stay in the intensive care unit have been reported to be risk factors for developing POCD for cardiac surgery. In the present study, the risk factors of early POCD after colorectal surgery were investigated.

Methods

Eighty patients, who provided informed consents for their participation in this study, were enrolled and received colorectal surgery under general anesthesia. Neuropsychological tests were performed preoperatively and on postoperative day seven. The risk factors for POCD were analyzed using a multivariate logistic regression model.

Results

Nineteen patients were diagnosed with POCD (24.7%). Diabetes history (OR = 8.391 [2.208–31.882], P = 0.012), fasting over 3 days after surgery (OR = 5.236 [1.998–13.721], P = 0.001) and an SIRS score of > 3 on the second day after surgery (OR = 6.995 [1.948–25.111], P = 0.003) were risk factors for early POCD in colorectal cancer patients.

Conclusion

The risk factors for early POCD after colorectal surgery included diabetes history, fasting over 3 days, and an SIRS score of > 3 on the second day.

Feeding Advancement and Simultaneous Transition to Discharge (FASTDischarge) after laparoscopic gastrostomy

BACKGROUND

Laparoscopic gastrostomy (LG) is a common surgical procedure. However, there is little consensus on a postoperative feeding regimen. With prior nasogastric feed tolerance, there should be no delay in resumption of feeds and subsequent discharge to home. This is a report on a Feeding Advancement and Simultaneous Transition-Discharge (FAST-Discharge) pathway, which to date has not been reported in the literature.

METHODS

A retrospective review of patients who underwent LG was performed from May 2010 to May 2015. All were outpatients who were on prior nasogastric feeds. The postoperative order set initiates feeds in 4 h to advance to goal as tolerated. Time to initial feed and goal nutrition, and overall length of stay (LOS) were evaluated.

RESULTS

122 patients were identified with 55% percent being male and with a median operative age of 15 months (IQR 8-27). 53% were started on bolus feeds. Initial feeds were started at a median of 2.8 h (IQR: 1.8-4.7). The median duration to goal nutrition was 6 h (IQR: 0-14). 97% reached full feeds within 24 h with no complications related to feed advancement. Median LOS was 26 h (IQR: 24-30).

CONCLUSION

An expedited pathway with early feeding and discharge is possible after laparoscopic gastrostomy tube placement with a low risk for adverse events.

Early enteral nutrition within 24 hours of lower gastrointestinal surgery versus later commencement for length of hospital stay and postoperative complications

BACKGROUND

This is an update of the review last published in 2011. It focuses on early postoperative enteral nutrition after lower gastrointestinal surgery. Traditional management consisted of 'nil by mouth', where patients receive fluids followed by solids after bowel function has returned. Although several trials have reported lower incidence of infectious complications and faster wound healing upon early feeding, other trials have shown no effect. The immediate advantage of energy intake (carbohydrates, protein or fat) could enhance recovery with fewer complications, and this warrants a systematic evaluation.

OBJECTIVES

To evaluate whether early commencement of postoperative enteral nutrition (within 24 hours), oral intake and any kind of tube feeding (gastric, duodenal or jejunal), compared with traditional management (delayed nutritional supply) is associated with a shorter length of hospital stay (LoS), fewer complications, mortality and adverse events in patients undergoing lower gastrointestinal surgery (distal to the ligament of Treitz).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Library 2017, issue 10), Ovid MEDLINE (1950 to 15 November 2017), Ovid Embase (1974 to 15 November 2017). We also searched for ongoing trials in ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform (15 November 2017). We handsearched reference lists of identified studies and previous systematic reviews.

SELECTION CRITERIA

We included randomised controlled trials (RCT) comparing early commencement of enteral nutrition (within 24 hours) with no feeding in adult participants undergoing lower gastrointestinal surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study quality using the Cochrane 'Risk of bias' tool tailored to this review and extracted data. Data analyses were conducted according to the Cochrane recommendations.We rated the quality of evidence according to GRADE.Primary outcomes were LoS and postoperative complications (wound infections, intraabdominal abscesses, anastomotic dehiscence, pneumonia).Secondary outcomes were: mortality, adverse events (nausea, vomiting), and quality of life (QoL).LoS was estimated using mean difference (MD (presented as mean +/- SD). For other outcomes we estimated the common risk ratio (RR) and calculated the associated 95% confidence intervals. For analysis, we used an inverse-variance random-effects model for the primary outcome (LoS) and Mantel-Haenszel random-effects models for the secondary outcomes. We also performed Trial Sequential Analyses (TSA).

MAIN RESULTS

We identified 17 RCTs with 1437 participants undergoing lower gastrointestinal surgery. Most studies were at high or unclear risk of bias in two or more domains. Six studies were judged as having low risk of selection bias for random sequence generation and insufficient details were provided for judgement on allocation concealment in all 17 studies. With regards to performance and deception bias; 14 studies reported no attempt to blind participants and blinding of personnel was not discussed either. Only one study was judged as low risk of bias for blinding of outcome assessor. With regards to incomplete outcome data, three studies were judged to be at high risk because they had more than 10% difference in missing data between groups. For selective reporting, nine studies were judged as unclear as protocols were not provided and eight studies had issues with either missing data or incomplete reporting of results.LOS was reported in 16 studies (1346 participants). The mean LoS ranged from four days to 16 days in the early feeding groups and from 6.6 days to 23.5 days in the control groups. Mean difference (MD) in LoS was 1.95 (95% CI, -2.99 to -0.91, P < 0.001) days shorter in the early feeding group. However, there was substantial heterogeneity between included studies (I² = 81, %, Chi² = 78.98, P < 0.00001), thus the overall quality of evidence for LoS is low. These results were confirmed by the TSA showing that the cumulative Z-curve crossed the trial sequential monitoring boundary for benefit.We found no differences in the incidence of postoperative complications: wound infection (12 studies, 1181 participants, RR 0.99, 95%CI 0.64 to 1.52, very low-quality evidence), intraabdominal abscesses (6 studies, 554 participants, RR 1.00, 95%CI 0.26 to 3.80, low-quality evidence), anastomotic leakage/dehiscence (13 studies, 1232 participants, RR 0.78, 95%CI 0.38 to 1.61, low-quality evidence; number needed to treat for an additional beneficial outcome (NNTB) = 100), and pneumonia (10 studies, 954 participants, RR 0.88, 95%CI 0.32 to 2.42, low-quality evidence; NNTB = 333).Mortality was reported in 12 studies (1179 participants), and showed no between-group differences (RR = 0.56, 95%CI, 0.21 to 1.52, P = 0.26, I² = 0%, Chi² = 3.08, P = 0.96, low-quality evidence). The most commonly reported cause of death was anastomotic leakage, sepsis and acute myocardial infarction.Seven studies (613 participants) reported vomiting (RR 1.23, 95%CI, 0.96 to 1.58, P = 0.10, I² = 0%, Chi² = 4.98, P = 0.55, low-quality evidence; number needed to treat for an additional harmful outcome (NNTH) = 19), and two studies (118 participants) reported nausea (RR 0.95, 0.71 to 1.26, low-quality evidence). Four studies reported combined nausea and vomiting (RR 0.94, 95%CI 0.51 to 1.74, very low-quality evidence). One study reported QoL assessment; the scores did not differ between groups at 30 days after discharge on either QoL scale EORTC QLQ-C30 or EORTC QlQ-OV28 (very low-quality evidence).

AUTHORS' CONCLUSIONS

This review suggests that early enteral feeding may lead to a reduced postoperative LoS, however cautious interpretation must be taken due to substantial heterogeneity and low-quality evidence. For all other outcomes (postoperative complications, mortality, adverse events, and QoL) the findings are inconclusive, and further trials are justified to enhance the understanding of early feeding for these. In this updated review, only a few additional studies have been included, and these were small and of poor quality.To improve the evidence, future trials should address quality issues and focus on clearly defining and measuring postoperative complications to allow for better comparison between studies. However due to the introduction of fast track protocols which already include an early feeding component, future trials may be challenging. A more feasible trial may be to investigate the effect of differing postoperative energy intake regimens on relevant outcomes.

Practice Changes in Postoperative Feeding after Elective Colorectal Surgery: From Prospective Randomized Study to Everyday Practice

Early postoperative feeding is the standard of care after colorectal surgery and is associated with improved outcomes. A controlled study performed at our center demonstrated faster bowel function recovery and shorter hospital stay without an increase in postoperative morbidity for a solid versus clear-liquid diet on postoperative day (POD) 1 after colorectal surgery. The present study aims to evaluate the impact of these findings on the practice of diet advancement by board-certified general surgeons (GS) and colorectal surgeons (CRS) at an urban teaching hospital. Patients undergoing elective colorectal surgery were prospectively evaluated. Data were compared with that of a study cohort that underwent elective colorectal surgery reported in 2012. Early postoperative feeding in the more recent cohort statistically increased for all cases on POD 0 and POD 1. Diet advancement over time revealed significant changes in early feeding on POD 0 for patients operated on by CRS (0% vs 83%; P < 0.0001) but not GS (13% vs 13%; P = 1). Patients operated on by either CRS or GS and offered early feeding on POD 1 did not significantly differ between time periods. Despite well-documented evidence of the advantages of early feeding, GS, but not CRS, remain reluctant to administer early diets to patients after colorectal surgery.

Early oral feeding after colorectal surgery: A mixed methods study of knowledge translation

AIM

Evidence-based guidelines recommend early oral feeding (EOF) as prescription of an unrestricted diet within 24 hours after colorectal surgery. The present study aimed to understand local postoperative feeding practices after colorectal surgery; identify barriers to EOF implementation; select, tailor and implement stakeholder engagement strategies to facilitate EOF uptake; and evaluate changes to practice.

METHODS

A longitudinal, mixed methods study was undertaken, guided by the knowledge-to-action framework. Phase 1 assessed the nature of the problem using postoperative diet Audits 1 and 2. In Phase 2, staff interviews identified barriers to EOF implementation. Results from Phases 1 and 2 were fed back to inform Phase 3 strategies. Knowledge uptake was monitored in Audits 3 and 4. Phase 4 evaluated outcomes from Audit 5.

RESULTS

In Phase 1, median time to commencement of full diet was postoperative Days 4 and 3 in Audits 1 and 2, respectively. Phase 2 identified EOF barriers, including disparities in diet upgrade practices and variable understanding of hospital diets. In Phase 3, planned strategies were implemented to improve EOF (i) educational session describing local hospital diets; (ii) consultant decision to prescribe a full diet on operation notes; and (iii) educational sessions with nursing staff describing changes to EOF practice. In Phase 4, median time to commencement of full diet improved to postoperative Day 0. Patients prescribed a full diet on operation notes increased from 0% to 82%.

CONCLUSIONS

The present study successfully identified and overcame local barriers to improve EOF practices to align with guideline recommendations.

PROGRAM OF INTESTINAL REHABILITATION AND EARLY POSTOPERATIVE ENTERAL NUTRITION: A PROSPECTIVE COHORT STUDY

Background:

Some factors can act on nutritional status of patients operated for a gastrointestinal cancer. A timely and appropriate nutritional intervention could have a positive effect on postoperative outcomes.

Aim:

To determine the effect of a program of intestinal rehabilitation and early postoperative enteral nutrition on complications and clinical outcomes of patients underwent gastrointestinal surgery for cancer.

Methods:

This is a prospective study of 465 patients underwent gastrointestinal surgery for cancer consecutively admitted in an oncological intensive care unit. The program of intestinal rehabilitation and early postoperative enteral nutrition consisted in: 1) general rules, and 2) gastrointestinal rules.

Results:

The mean age of analysed patients was 63.7±9.1 years. The most frequent operation sites were colon-rectum (44.9%), gynaecological with intestinal suture (15.7%) and oesophagus-gastric (11.0%). Emergency intervention was performed in 12.7% of patients. The program of intestinal rehabilitation and early postoperative enteral nutrition reduced major complication (19.2% vs. 10.2%; p=0.030), respiratory complications (p=0.040), delirium (p=0.032), infectious complications (p=0.047) and gastrointestinal complications (p<0.001), mainly anastomotic leakage (p=0.033). The oncological intensive care unit mortality (p=0.018), length of oncological intensive care unit (p<0.001) and hospital (p<0.001) stay were reduced as well.

Conclusions:

Implementing a program of intestinal rehabilitation and early postoperative enteral nutrition is associated with reduction in postoperative complications and improvement of clinical outcomes in patients undergoing gastrointestinal surgery for cancer.

Pharmaconutrition administration on outcomes of elective oncological surgery for gastrointestinal malignancies: is timing everything?-a review of published meta-analyses until the end of 2016

The last 25 years have seen an increasing number of publications attesting the benefits of pharmaconutrition in the management of patients undergoing elective oncological gastrointestinal surgery. A number of randomized controlled trials and meta-analyses suggest the use of pharmaconutrition in this group of patients produces superior outcomes to standard nutritional formulations in terms of postoperative infective complications, anastomotic breakdown and length of hospital stay. The use of pharmaconutrition products, therefore, has gained increasing acceptance for use in elective gastrointestinal oncological surgical populations and been incorporated into practice guidelines. However, there remains doubts as to the robustness of such data supporting these recommendation. This is because studies reporting improved outcomes with pharmaconutrition (I) frequently compare this intervention with non-equivalent control groups; (II) do not report on the actual nutritional provision received by study participants; (III) overlook the potential impact of industry funding on research conducted and (IV) do not adopt a multi-disciplinary approach to the research undertaken. For these reasons, a critical re-appraisal of the use and recommendations of pharmaconutrition in this group of patients is urgently warranted to resolve some of the above mentioned issues. The aim of this review was to analyse meta-analyses published until the end of 2016 in this area to highlight the strengths and weakness of the present research and prioritize certain areas which will benefit from future research.

Current perspective for tube feeding in the elderly: from identifying malnutrition to providing of enteral nutrition

With the number of individuals older than 65 years expected to rise significantly over the next few decades, dramatic changes to our society and health care system will need to take place to meet their needs. Age-related changes in muscle mass and body composition along with medical comorbidities including stroke, dementia, and depression place elderly adults at high risk for developing malnutrition and frailty. This loss of function and decline in muscle mass (ie, sarcopenia) can be associated with reduced mobility and ability to perform the task of daily living, placing the elderly at an increased risk for falls, fractures, and subsequent institutionalization, leading to a decline in the quality of life and increased mortality. There are a number of modifiable factors that can mitigate some of the muscle loss elderly experience especially when hospitalized. Due to this, it is paramount for providers to understand the pathophysiology behind malnutrition and sarcopenia, be able to assess risk factors for malnutrition, and provide appropriate nutrition support. The present review describes the pathophysiology of malnutrition, identifies contributing factors to this condition, discusses tools to assess nutritional status, and proposes key strategies for optimizing enteral nutrition therapy for the elderly.

Clinical pathway after gastrectomy for gastric cancer: A case series of laparoscopic gastrectomy and early oral intake with "iEat™"

INTRODUCTION

We investigated the validity of the clinical pathway of early oral intake using a special type of food "iEat™" for patients after laparoscopic gastric cancer surgery.

METHODS

Fifty-two patients who underwent laparoscopic surgery for gastric cancer between April 2012 and October 2013 were the participants. We provided postoperative care in accordance with a clinical pathway for laparoscopic gastrectomy that begins oral intake with "iEat™ the day after surgery. We examined complications resulting from oral intake, postoperative complications, and the length of postoperative hospital stay.

RESULTS

Of the 52 patients, 30 underwent distal gastrectomy and 22 underwent total gastrectomy. 50 patients was able to start early oral intake in accordance with our clinical pathway. No anastomotic leak complications were observed, and 9 patients (17.3%) developed complications as results of surgery. There was no complication related to early oral intake with "iEat™". Re-operation were performed in two cases. Overall mean and median postoperative hospital stays were 8.3 days and 6 days, respectively. There was a single case of hospital re-admission. The completion rate of this early oral intake clinical pathway was 86.5%.

CONCLUSION

Clinical pathway of recovery program combined laparoscopic suregry and early oral intake with "iEat™" could be useful for gastric cancer. This study indicates that using non-liquid food like iEat™ can be feasiblel, and water or liquid food don't have to be used in early oral feeding after laparoscopic gastrectomy.

Feeding Practices and Nutrition Intakes Among Non-Critically Ill, Postoperative Adult Patients: An Observational Study

BACKGROUND

Evidence-based guidelines (EBG) recommend recommencing oral feeding (liquids and solids) ≤24 hours after surgery. The aims of this study were to determine time to first diet (any) and solid-diet prescriptions, delivery, and intakes among adult, non-critically ill, postoperative patients.

METHODS

This prospective cross-sectional study included 100 postsurgical patients. Demographic and perioperative dietary-related data were collected from patients' medical records or via direct observation. Dietary intakes were observed for the duration patients were enrolled in the study (from end of surgery to discharge). The amount of energy (kcal) and protein (g) consumed per patient per day was analyzed and considered adequate if it met ≥75% of a patient's estimated requirements.

RESULTS

89 and 52 patients consumed their first intake and first solid intake ≤24 hours after surgery, respectively. For their first intake, 53% of patients had clear or free liquids. Median times to first diet prescription (range: 1.3-5.7 hours), delivery (range: 2.1-12.5 hours), and intake (range: 2.2-13.9 hours) were ≤24 hours after surgery for all patient groups. Time to first solid-diet prescription (range: 1.3-77.8 hours), delivery (range: 2.1-78.0 hours) and intake (range: 2.2-78.2 hours) varied considerably. Urologic and gastrointestinal patients experienced the greatest delays to first solid-diet prescription and first solid intake. Only 26 patients met both their energy and protein requirements for ≥1 day during their stay.

CONCLUSION

While practice appears consistent with EBG recommendations for commencing nutrition (any type) after surgery, the reintroduction of adequate diet requires improvement.

Early Enteral Nutrition is Associated with Reduced Morbidity in Critically Ill Soft Tissue Patients

Soft tissue diseases including necrotizing soft tissue infections are associated with high mortality and morbidity with hospital-acquired infection rates up to 76 per cent. Critically ill patients with soft tissue infections have increased metabolic requirements; however, the effect of early nutrition on inhospital morbidity including nosocomial infection rates remains unclear. We hypothesized that enteral nutrition within 48 hours of intensive care unit admission would be associated with fewer hospital-acquired infections. We conducted a retrospective review of patients with soft tissue infection requiring intensive care unit admission for >72 hours from January 2013 through December 2014 to a high-volume, dedicated soft tissue service. Variables were compared using chisquared, Student's t test, linear regression, and binary logistic regression analysis. Eighty-five patients met inclusion criteria; 80 per cent started enteral nutrition within 48 hours. Twenty-six per cent had a hospital-acquired infection postadmission requiring treatment. Patients started on enteral nutrition within 48 hours had fewer ventilator days (mean 5 vs 12) and shorter hospital length of stay (mean 18 vs 40 days) when adjusted for age, gender, and confounding variables present on admission. Patients receiving early nutrition also had fewer hospital-acquired infections (18 vs 59%) when adjusted for confounding factors (aOR 0.15, P = 0.045). No significant difference in mortality (13.2% early vs 5.9% late, P = 0.4) or for inhospital morbidity when evaluating percentage of goal calories or protein received or time to goal tube feed rate was found. Early enteral feeding is associated with reduced inhospital morbidity in critically ill soft tissue patients, including fewer hospital-acquired infections and ventilator days, and shorter total length of stay.

Current Evidence about Nutrition Support in Cardiac Surgery Patients-What Do We Know?

Nutrition support is increasingly recognized as a clinically relevant aspect of the intensive care treatment of cardiac surgery patients. However, evidence from adequate large-scale studies evaluating its clinical significance for patients&rsquo; mid- to long-term outcome remains sparse. Considering nutrition support as a key component in the perioperative treatment of these critically ill patients led us to review and discuss our understanding of the metabolic response to the inflammatory burst induced by cardiac surgery. In addition, we discuss how to identify patients who may benefit from nutrition therapy, when to start nutritional interventions, present evidence about the use of enteral and parenteral nutrition and the potential role of pharmaconutrition in cardiac surgery patients. Although the clinical setting of cardiac surgery provides advantages due to its scheduled insult and predictable inflammatory response, researchers and clinicians face lack of evidence and several limitations in the clinical routine, which are critically considered and discussed in this paper.

Program of gastrointestinal rehabilitation and early postoperative enteral nutrition: a prospective study

Nutritional depletion is commonly observed in patients undergoing surgical treatment for a gastrointestinal malignancy. An appropriate nutritional intervention could be associated with improved postoperative outcomes. The study was aimed to determine the effect of a program of gastrointestinal rehabilitation and early postoperative enteral nutrition upon complications and clinical outcomes in patients who experienced gastrointestinal surgery for cancer. This is a prospective study (2013 January-2015 December) of 465 consecutive patients submitted to gastrointestinal surgery for cancer and admitted to an Oncological Intensive Care Unit. The program of gastrointestinal rehabilitation and early postoperative enteral nutrition consisted on: (1) general rules: pain relive, early mobilization, antibiotic prophylaxis, deep vein thrombosis prophylaxis and respiratory physiotherapy; and (2) gastrointestinal rules: gastric protection, control of postoperative nausea and vomiting, early nasogastric tube remove and early enteral nutrition. The most frequent surgical sites were colorectal (44.9%), gynecological with intestinal suturing (15.7%) and esophagus/stomach (11.0%). Emergency surgery was performed in 12.7% of patients. The program of intestinal rehabilitation and early postoperative enteral nutrition reduced major complications (19.2 vs. 10.2%; p = 0.030), respiratory complications (p = 0.040), delirium (p = 0.032), infectious complications (p = 0.047) and gastrointestinal complications (p < 0.001). Intensive care unit mortality (p = 0.018), length of intensive care unit stay (p < 0.001) and length of hospitalization (p < 0.001) were reduced as well. A program of gastrointestinal rehabilitation and early postoperative enteral nutrition is associated with reduced postoperative complications and improved clinical outcomes in patients undergoing gastrointestinal surgery for cancer.

2017 WSES guidelines for the management of iatrogenic colonoscopy perforation

Iatrogenic colonoscopy perforation (ICP) is a severe complication that can occur during both diagnostic and therapeutic procedures. Although 45–60% of ICPs are diagnosed by the endoscopist while performing the colonoscopy, many ICPs are not immediately recognized but are instead suspected on the basis of clinical signs and symptoms that occur after the endoscopic procedure. There are three main therapeutic options for ICPs: endoscopic repair, conservative therapy, and surgery. The therapeutic approach must vary based on the setting of the diagnosis (intra- or post-colonoscopy), the type of ICP, the characteristics and general status of the patient, the operator’s level of experience, and surgical device availability.

Although ICPs have been the focus of numerous publications, no guidelines have been created to standardize the management of ICPs. The aim of this article is to present the World Society of Emergency Surgery (WSES) guidelines for the management of ICP, which are intended to be used as a tool to promote global standards of care in case of ICP. These guidelines are not meant to substitute providers’ clinical judgment for individual patients, and they may need to be modified based on the medical team’s level of experience and the availability of local resources.

Enhanced Recovery After Surgery for Radical Cystectomy

Even with advances in perioperative medical care, anesthetic management, and surgical techniques, radical cystectomy (RC) continues to be associated with a high morbidity rate as well as a prolonged length of hospital stay. In recent years, there has been great interest in identifying multimodal and interdisciplinary strategies that help accelerate postoperative convalescence by reducing variation in perioperative care of patients undergoing complex surgeries. Enhanced recovery after surgery (ERAS) attempts to evaluate and incorporate scientific evidence for modifying as many of the factors contributing to the morbidity of RC as possible, and optimize how patients are cared for before and after surgery. In this chapter, we review the preoperative, intraoperative and postoperative elements of using an ERAS protocol for RC.

Influence of nutritional status on postoperative outcome in patients with colorectal cancer - the emerging role of the microbiome

Many patients with colorectal cancer are overweight. Even then, nutritional status is a frequently underestimated risk factor for perioperative complications. Enhanced Recovery after Surgery is the goal for perioperative management, and preoperative nutritional risk screening should be a standard. In case of nutritional risk, perioperative nutrition therapy should be started without delay and should follow recent guideline recommendations. The preservation of the microbiome has an emerging role in preventing postoperative anastomotic leakage and septic complications. The time window for recovery after neoadjuvant treatment for rectal cancer may be used for conditioning appropriate-risk patients in a “prehabilitation” program. In order to assess metabolic recovery and the prognosis for long-term survival, C-reactive protein/albumin ratio may be a promising parameter, which has to be validated in the future. This narrative review summarizes recent strategies and guideline recommendations.

Research progress of fast track surgery

The purpose of surgical treatment is to remove the lesions, repair tissue, and reconstruct organ function, but the process will inevitably cause certain degrees of trauma and stress. As a traumatic treatment, surgical treatment can produce a series of pathophysiological changes while achieving the therapeutic effect. Surgical complications are significantly associated with perioperative stress. Therefore, controlling operation-related stress can effectively improve prognosis. In order to reduce the incidence of surgical stress and postoperative complications and promote the rehabilitation of patients as soon as possible, the concept of fast track surgery has been put forward in recent years. It is supported by evidence-based medicine and subverts the traditional concept of surgery, optimizing the multidisciplinary cooperation in the perioperative treatment and rehabilitation process. Moreover, it accelerates the recovery of postoperative patients. Since the concept was put forward, it has been widely applied in European and American countries in the fields of gastroenterology, cardiothoracic surgery, orthopedics, urology, and gynecology. This paper briefly reviews the advances of fast track surgery in recent years.

ACERTO guidelines of perioperative nutritional interventions in elective general surgery

ABSTRACT Objective: to present recommendations based on the ACERTO Project (Acceleration of Total Post-Operative Recovery) and supported by evidence related to perioperative nutritional care in General Surgery elective procedures. Methods: review of relevant literature from 2006 to 2016, based on a search conducted in the main databases, with the purpose of answering guiding questions previously formulated by specialists, within each theme of this guideline. We preferably used randomized controlled trials, systematic reviews and meta-analyzes but also selected some cohort studies. We contextualized each recommendation-guiding question to determine the quality of the evidence and the strength of this recommendation (GRADE). This material was sent to authors using an open online questionnaire. After receiving the answers, we formalized the consensus for each recommendation of this guideline. Results: the level of evidence and the degree of recommendation for each item is presented in text form, followed by a summary of the evidence found. Conclusion: this guideline reflects the recommendations of the group of specialists of the Brazilian College of Surgeons, the Brazilian Society of Parenteral and Enteral Nutrition and the ACERTO Project for nutritional interventions in the perioperative period of Elective General Surgery. The prescription of these recommendations can accelerate the postoperative recovery of patients submitted to elective general surgery, with decrease in morbidity, length of stay and rehospitalization, and consequently, of costs.

Prehabilitation and Nutritional Support to Improve Perioperative Outcomes

PURPOSE OF REVIEW

The purpose of this study is to evaluate the role of physical exercise and nutrition interventions in adult patients before elective major surgery.

RECENT FINDINGS

Exercise training before elective adult major surgery is feasible, safe, and efficacious, but the clinical effectiveness remains uncertain. Early data suggests a reduction in morbidity, length of stay, and quality of life, but the results of larger definitive studies are awaited. Nutritional interventions are less well evaluated and when they are, it is often in combination with exercise interventions as part of a prehabilitation package.

SUMMARY

Studies evaluating exercise and nutrition interventions before elective major surgery in adults are producing encouraging early results, but definitive clinical evidence is currently very limited. Future research should focus on refining interventions, exploring mechanism, and evaluating the interactions between therapies and large-scale clinical effectiveness studies.

Bladder Cancer Recovery Pathways: A Systematic Review

BACKGROUND

Enhanced recovery pathways, also known as fast-track protocols, have been adopted since the early 2000s by various surgical specialties with the goal of improving patient outcomes and reducing the cost burden of major surgery on the health care system.

OBJECTIVE

To review the scientific literature on the origin of enhanced recovery pathways, track the contemporary utilization of such practices for patients undergoing radical cystectomy, and analyze the available data regarding their effect on morbidity, mortality, and treatment cost.

METHODS

A literature search of multiple electronic databases was undertaken. Manuscripts including patients undergoing radical cystectomy were chosen based on predefined criteria with an emphasis on randomized controlled trials and cohort studies. Strength of evidence for each study that met inclusion criteria was assessed based on the risk of bias, consistency, directness, and precision.

RESULTS

Database searches resulted in 1,236 potentially relevant articles. A total of 485 articles were selected for full-text dual review and 106 studies in 52 publications met the inclusion criteria.

CONCLUSION

The utilization of enhanced recovery pathways with the goal of improving overall patient morbidity and mortality is well supported in the literature, however standardization of implementation and adherence across institutions is lacking, and their direct efficacy on reducing preventable treatment related expenditures is unconfirmed.

Does having a gastrectomy delay time to feeding and prolong hospital stay in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy?

AIM

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is routinely used to treat selected patients with peritoneal carcinomatosis, but can be associated with prolonged hospital stay, significant morbidity and mortality. Our objective was to assess whether patients undergoing gastrectomy as part of CRS/HIPEC were at increased risk of delayed feeding time and prolonged hospital stay.

METHODS

Two hundred and fourteen consecutive patients with peritoneal carcinomatosis treated with CRS/HIPEC between 2001 and 2016 were stratified by whether CRS included gastrectomy (n = 19, 9%) and compared. Primary outcomes were time to full feeds and rate of serious morbidity (Clavien-Dindo grades III-V). Secondary outcomes were durations of ICU and hospital stays.

RESULTS

Of 214 patients undergoing CRS/HIPEC, those undergoing gastrectomy (19, 8.9%) had increased time to full feeds (8 vs. 5 days, p < 0.01), and duration of ICU (2 vs. 1 days, p < 0.01) and total hospital stays (16 vs. 14 days, p = 0.013). There was no significant increase in serious complications, although increased risk of pneumonia was noted (21% vs. 4.1%, p = 0.011). Undergoing gastrectomy was not independently prognostic in multivariable analysis including high peritoneal tumour load (PCI >12), multiple CRS procedures (number >2) and operation duration (>480 min) in which operative duration remained independently prognostic (p < 0.01).

CONCLUSIONS

After surgery, early oral refeeding may be beneficial in the majority of patients undergoing CRS/HIPEC. However, patients found to have high peritoneal tumour load with extended surgery and those who underwent gastrectomy should be considered for early post-operative TPN due to the significant risk of delayed time to full feeds.
