Randomized Controlled Trial Comparing the Short-term Outcomes of Enhanced Recovery After Surgery and Conventional Care in Laparoscopic Distal Gastrectomy (GISSG1901)

The efficacy and safety of enhanced recovery after surgery (ERAS) Program in laparoscopic distal gastrectomy: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Although ERAS Program had some advantages in laparoscopic distal gastrectomy (LDG), its efficacy and safety remained unclear. We conducted a systematic review and meta-analysis to assess the efficacy and safety of the ERAS group and the traditional care (TC) group in LDG.

METHODS

Multiple databases were retrieved from 1 January 2000 to 30 April 2023. The risk ratio (RR), standardized mean difference (SMD) and their 95% confidence interval (CI) were used to estimate the results.

RESULTS

Our meta-analysis contained 17 randomized controlled trials (RCTs) studies, which comprised 1468 patients. Regarding efficacy, the ERAS group had significantly shorter postoperative time to first flatus (SMD = -1.29 [95% CI: -1.68, -0.90]), shorter time to first defecation (SMD = -1.26 [95% CI: -1.90, -0.61]), shorter hospital stays (SMD = -0.99 [95% CI: -1.34, -0.63]), and lower hospitalization costs (SMD = -1.17 [95% CI: -1.86, -0.48]) compared to the TC group. Furthermore, in the ERAS group, C-reactive protein levels were lower on postoperative days 1, 3 or 4, and 7; albumin levels were higher on postoperative days 3 or 4 and 7; and interleukin-6 levels were lower on postoperative days 1 and 3. Regarding safety, the overall postoperative complication rate was lower in the ERAS group (RR: 0.76 [95% CI: 0.60, 0.97]), but there was no significant difference in the individual postoperative complication rate. Other indicators were also not statistically significant.

CONCLUSION

The combination of ERAS Program with laparoscopy surgery was safe and effective for the perioperative management of patients with distal gastric cancer.

Enhanced recovery after surgery-based nursing in older patients with postoperative intestinal obstruction after gastric cancer surgery: A retrospective study

BACKGROUND

Gastric cancer-related morbidity and mortality rates are high in China. Patients who have undergone gastric cancer surgery should receive six cycles of chemotherapy according to their condition. During this period, intestinal obstruction is likely to occur. Electrolyte balance disorders, peritonitis, intestinal necrosis, and even hypovolemic shock and septic shock can seriously affect the physical and mental recovery of patients and threaten their health and quality of life (QoL).

AIM

To quantitatively explore the effects of enhanced recovery after surgery (ERAS)–based nursing on anxiety, depression, and QoL of elderly patients with postoperative intestinal obstruction after gastric cancer.

METHODS

The clinical data of 129 older patients with intestinal obstruction after gastric cancer surgery who were treated and cared for in our hospital between January 2019 and December 2021 were examined retrospectively. Nine patients dropped out because of transfer, relocation, or death. According to the order of admissions, the patients were categorized into either a comparison group or an observation group according to the random number table, with 60 cases in each group.

RESULTS

After nursing care, the observation group required significantly less time to eat for the first time, recover bowel sounds, pass gas, and defecate than the comparison group (P < 0.05). No significant difference was noted in nutrition-related indicators between the two groups before care. Before care, the Symptom Check List-90 scores between the two groups were comparable, whereas anxiety, depression, paranoia, fear, hostility, obsession, somatization, interpersonal sensitivity, and psychotic scores were significantly lower in the observation group after care (P < 0.05). The QoL scores between the two groups before care did not differ significantly. After care, the physical, social, physiological, and emotional function scores; mental health score; vitality score; and general health score were significantly higher in the observation group, whereas the somatic pain score was significantly lower in the observation group (P < 0.05).

CONCLUSION

ERAS-based nursing combined with conventional nursing interventions can effectively improve patient’s QoL, negative emotions, and nutritional status; accelerate the time to first ventilation; and promote intestinal function recovery in elderly patients with postoperative intestinal obstruction after gastric cancer surgery.

Enhanced recovery after surgery from 1997 to 2022: a bibliometric and visual analysis

Enhanced recovery after surgery (ERAS) is a multimodal perioperative management concept, but there is no article to comprehensively review the collaboration and impact of countries, institutions, authors, journals, references, and keywords on ERAS from a bibliometric perspective. This study assessed the evolution of clustering of knowledge structures and identified hot trends and emerging topics. Articles and reviews related to ERAS were retrieved through subject search from the Web of Science Core Collection. We used the following strategy: "TS = Enhanced recovery after surgery" OR "Enhanced Postsurgical Recovery" OR "Postsurgical Recoveries, Enhanced" OR "Postsurgical Recovery, Enhanced" OR "Recovery, Enhanced Postsurgical" OR "Fast track surgery" OR "improve surgical outcome". Bibliometric analyses were conducted on Excel 365, CiteSpace, VOSviewer, and Bibliometrics (R-Tool of R-Studio). Totally 3242 articles and reviews from 1997 to 2022 were included. These publications were mainly from 684 journals in 78 countries, led by the United States and China. Kehlet H published the most papers and had the largest number of co-citations. Analysis of the journals with the most outputs showed that most journals mainly cover Surgery and Oncology. The hottest keyword is "enhanced recovery after surgery". Later appearing topics and keywords indicate that the hotspots and future research trends include ERAS protocols for other types of surgery and improving perioperative status, including "bariatric surgery", "thoracic surgery", and "prehabilitation". This study reviewed the research on ERAS using bibliometric and visualization methods, which can help scholars better understand the dynamic evolution of ERAS and provide directions for future research.

Risk factor analysis and nomogram construction of postoperative complications for patients with locally advanced gastric cancer who received neoadjuvant immunotherapy and chemotherapy

Introduction

The combination of neoadjuvant immunotherapy and chemotherapy (NICT) has become a common treatment regimen for locally advanced gastric cancer (LAGC). However, the safety and efficacy of radical gastrectomy following NICT (NICT-G) remain controversial. This study aimed to analyze the risk factors influencing postoperative complications (POCs) after NICT-G. Additionally, it aimed to construct a nomogram to provide a clinical reference for predicting POCs.

Methods

This study included 177 patients who received NICT-G at the Chinese PLA General Hospital First Medical Center from January 2020 to January 2024. Univariable and multivariable logistic regression models were used to evaluate the risk factors influencing POCs, and a nomogram model was constructed. To evaluate the discrimination and accuracy of the nomogram model, the area under the receiver operating characteristic curve (AUC) and the calibration curve were measured.

Results

In 177 patients who received NICT-G, the pathological complete response and major pathological response rates were 15.8% and 45.2%, respectively, whereas the rates of the overall and severe treatment-related adverse events were 71.8% and 15.8%, respectively. In addition, 43 (24.3%) patients developed overall POCs (Clavien-Dindo classification ≥ II). Univariable and multivariable logistic analyses showed that age ≥70 years, greater estimated blood loss, platelet/lymphocyte ratio (PLR) ≤196, neutrophil/lymphocyte ratio (NLR) >1.33, non-R0 resection, and body mass index (BMI) < 18.5 kg/m2 were independent risk factors for overall POCs (p < 0.05). The nomogram model developed using the abovementioned variables showed that the AUC (95% confidence interval [CI]) was 0.808 (95% CI): 0.731-0.885 in predicting the POC risk. The calibration curves showed that the prediction curve of the nomogram was a good fit for the actual POCs (Hosmer-Lemeshow test: χ2 = 5.76, P = 0.451).

Conclusion

The independent risk factors for overall POCs in the NICT-G were age ≥ 70 years, greater estimated blood loss, PLR ≤ 196, NLR > 1.33, non-R0 resection, and BMI < 18.5 kg/m2. The nomogram model developed based on the abovementioned indicators showed better accuracy in predicting the POC risk.

The application of enhanced recovery after surgery protocol after distal gastrectomy for patients with gastric cancer: a prospective randomized clinical trial

BACKGROUND

This study aimed to evaluate the clinical outcomes and efficacy of enhanced recovery after surgery (ERAS) protocol in patients undergoing distal gastrectomy for gastric cancer (GC).

METHODS

Patients were randomly assigned to the ERAS group (EG) and the conventional care group (CG) by stratified randomization according to age and sex. The primary endpoint was adjusted postoperative hospital stay, calculated using discharge criteria developed to evaluate recovery. Nutritional data and quality of life (QoL) (European Organisation for Research and Treatment of Cancer [EORTC] C30 and STO22) during the perioperative period were also analyzed.

RESULTS

We enrolled 198 eligible patients with GC for the study between June 2017 and January 2019. A total of 147 patients were finally enrolled in this study (full analysis set) and were assigned to EG (n = 71) and CG (n = 76). First flatus was faster significantly in EG (3.6 ± 1.5 vs 4.1 ± 1.2 days, P = .019). EG showed a faster start of the sips and soft diet than CG (1.3 ± 0.7 vs 3.1 ± 0.4 days, P < .001; 2.4 ± 0.9 vs 5.2 ± 0.7 days, P < .001) according to the protocol. The recorded hospital stay was not significantly different; however, adjusted hospital stay was significantly shorter in EG than in CG (6.5 ± 3.1 vs 7.8 ± 2.1 days, P = .005). There was no difference in morbidity, and no mortality occurred in both groups. EG did not show significant superiority in nutritional outcome and QoL improvement, except for pain scale in EORTC-STO22.

CONCLUSION

The application of the ERAS protocol could reduce the adjusted hospital stay without an increase in postoperative complications. There was no significant difference in long-term nutritional outcome and QoL of the 2 groups.

A Path to High-Value Gastric Cancer Surgery Care Delivery

Objective

To evaluate the feasibility, safety, and effectiveness of a comprehensive regional program, including the Minimally Invasive Recovery and Empowerment Care (MIREC) pathway, that can significantly reduce hospital stays after laparoscopic gastrectomy without increasing adverse events.

Background

Cost-effectiveness and improving patient outcomes are crucial in providing quality gastric cancer care worldwide.

Methods

To compare the outcomes of gastric cancer surgery using 2 different models of care within an integrated healthcare system from February 2012 to March 2023. The primary endpoint was the length of hospital stay. The secondary endpoints were the need for intensive care unit care, emergency room (ER) visits, readmission, reoperation, and death within 30 days after surgery.

Results

There were 553 patients, 167 in the pre-(February 2012-April 2016) and 386 in the post-MIREC period (May 2016-March 2023). Perioperative chemotherapy utilization increased from 31.7% to 76.4% (P < 0.0001). Laparoscopic gastrectomy increased from 17.4% to 97.7% (P < 0.0001). Length of hospitalization decreased from 7 to 2 days (P < 0.0001), with 32.1% and 88% of patients discharged home on postoperative day 1 and postoperative day 2, respectively. When comparing pre- and post-MIREC, intensive care unit utilization (10.8% vs. 2.9%, P < 0.0001), ER visits (34.7% vs. 19.7%, P = 0.0002), and readmission (18.6% vs. 11.1%, P = 0.019) at 30 days were also considerably lower. In addition, more patients received postoperative adjuvant chemotherapy (31.4% to 63.5%, P < 0.0001), and the time between gastrectomy and starting adjuvant chemotherapy was also less (49-41 days; P = 0.002).

Conclusion

This comprehensive regional program, which encompasses regionalization care, laparoscopic approach, modern oncologic care, surgical subspecialization, and the MIREC pathway, can potentially improve gastric cancer surgery outcomes. These benefits include reduced hospital stays and lower complication rates. As such, this program can revolutionize how gastric cancer surgery is delivered, leading to a higher quality of care and increased value to patients.

Effect of preoperative immunonutrition on postoperative short-term clinical outcomes in patients with gastric cancer cachexia: a prospective randomized controlled trial

BACKGROUND

Although current guidelines(ESPEN guideline: Clinical nutrition in surgery and other guidelines) recommend preoperative immunonutrition for cachectic gastric cancer patients, the strength of the recommendation is weak, and the level of evidence is low. The benefits of preoperative immunonutrition still remain controversial.

PATIENTS AND METHODS

112 patients with gastric cancer cachexia were enrolled in the study and randomly assigned in a 1:1 ratio to receive either preoperative enteral immunonutrition support (IN, n = 56) or standard enteral nutrition support (SEN, n = 56). The primary endpoint was the incidence of infectious complications, and the secondary endpoints included the nutritional indicators, inflammatory markers, immune parameters, postoperative recovery and complications and gastrointestinal intolerance reactions.

RESULTS

The incidence of postoperative infectious complications(P = 0.040) and overall complications (P = 0.049)was significantly lower in the IN group compared to the SEN group. In terms of laboratory inflammatory indexes, patients in the IN group demonstrated significantly lower levels of white blood cells (WBC), C-reactive protein (CRP), and interleukin-6 (IL-6), as well as higher levels of lymphocytes (LYMPH) and immunoglobulin A (IgA), compared to patients in the SEN group, with statistically significant differences. In terms of clinical outcomes, the IN group had a shorter duration of antibiotic use (P = 0.048), shorter hospital stay (P = 0.018), and lower total hospital costs (P = 0.034) compared to the SEN group. The IN group also experienced significantly less weight loss after surgery (P = 0.043).

CONCLUSION

Preoperative administration of immunonutrition formula has a positive impact on the incidence of infectious complications in patients with gastric cancer cachexia after surgery. It improves patients' inflammatory and immune status, shortens hospital stays, and reduces healthcare costs. Preoperative use of immunonutrition may contribute to the improvement of prognosis in this high-risk population.

Short- and long-term comparison of robotic versus laparoscopic gastrectomy for gastric cancer patients with BMI≥30 kg/m2: A propensity score matched analysis

BACKGROUND

Although minimally invasive surgery (MIS) for gastric patients has gained popularity in recent decades, reports on the comparison of short and long clinical outcomes between robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) for gastric cancer patients with BMI≥30 kg/m2 are still limited.

METHODS

A total of 226 obese gastric cancer patients who underwent either RG (n = 81) or LG (n = 145) were enrolled in this study between October 2014 and September 2022. Propensity score matching (PSM) (1:1) was performed to reduce confounding bias. Short-term and long-term outcomes were compared between the RG and LG groups.

RESULTS

The clinicopathological characteristics of 156 patients in the RG group (n = 79) and LG group (n = 79) were well balanced after PSM. Compared with the LG group, the RG group had a significantly shorter operation time, less estimated blood loss, more harvested lymph nodes, a faster postoperative recovery course, reduced surgical morbidity, and a shorter postoperative hospital stay. The long-term outcomes were comparable between the two groups.

CONCLUSIONS

RG is a safe and feasible approach for gastric cancer with a BMI≥30 kg/m2 and has better short-term clinical outcomes than LG. However, RG is similar to LG in terms of long-term prognosis.

Evaluation of enhanced recovery after surgery for gastric cancer patients undergoing gastrectomy: a systematic review and meta-analysis

Introduction

For complicated surgical patients, enhanced recovery after surgery (ERAS) decreases stress and hospital stays. It accelerates recovery and lowers readmissions, morbidity, and death. ERAS's effectiveness in stomach cancer laparoscopic-assisted gastrectomy (LAG) or robotic gastrectomy is still debated.

Aim

This study assesses the efficacy and safety of the ERAS program for patients undergoing gastrectomy for gastric cancer.

Material and methods

PRISMA-compliant searches were performed in Medline, Embase, PubMed, the Web of Sciences, and the Cochrane Library databases until March 2023. The search included articles that compared ERAS protocol results for gastric cancer surgery patients to conventional care. RevMan performed meta-analysis, and the Cochrane Risk of Bias Assessment Tool assessed study quality.

Results

This meta-analysis contained 11 carefully chosen randomized controlled trials (RCTs) involving 1790 people. The ERAS group had 902 participants, while the traditional care group had 888. The ERAS group had a shorter post-operative hospital stay, with a weighted mean difference (WMD) of -1.12 days (95% CI: -1.89 to -0.35, p = 0.00001), I2 = 89%, and a lower number of patients with post-operative problems, with an odds ratio (OR) of 0.73 (95% CI: 0.55 to 0.97; p = 0.03), I2 = 60%.

Conclusions

The ERAS procedure has been shown to be effective as well as beneficial for patients undergoing either laparoscopic-assisted or robotic gastrectomy for gastric cancer, since it lowers post-operative complications and accelerates recovery with improved results.

Multimodal prehabilitation to improve the clinical outcomes of frail elderly patients with gastric cancer: a study protocol for a multicentre randomised controlled trial (GISSG+2201)

INTRODUCTION

Gastric cancer (GC) diagnosed in the elderly population has become a serious public health problem worldwide. Given the combined effects of frailty and the consequences of cancer treatment, older individuals with GC are more likely than young patients to suffer from postoperative complications and poor clinical outcomes. Nutrition, functional capacity and psychological state-based multimodal prehabilitation, which is dominated by Enhanced Recovery After Surgery (ERAS) pathway management, has been shown to reduce postoperative complications, promote functional recovery and decrease hospitalisation time in certain malignancies. However, no previous studies have investigated the clinical application of multimodal prehabilitation in frail older patients with GC.

METHODS AND ANALYSIS

The study is a prospective, multicentre randomised controlled trial in which a total of 368 participants who meet the inclusion criteria will be randomised into either a prehabilitation group or an ERAS group. The prehabilitation group will receive multimodal prehabilitation combined with ERAS at least 2 weeks before the gastrectomy is performed, including physical and respiratory training, nutritional support, and therapy and psychosocial treatment. The ERAS group patients will be treated according to the ERAS pathway. All interventions will be supervised by family members. The primary outcome measures are the incidence and severity of postoperative complications. Secondary outcomes include survival, functional capacity and other short-term postoperative outcomes. Overall, the multimodal prehabilitation protocol may improve functional capacity, reduce the surgical stress response and concomitant systemic inflammation, and potentially modulate the tumour microenvironment to improve short-term and long-term clinical outcomes and patients' quality of life.

ETHICS AND DISSEMINATION

All procedures and participating centres of this study were approved by their respective ethics committees (QYFYKYLL 916111920). The final study results will be published separately in peer-reviewed journals.

Grip strength is an important predictor for nutritional risk and early postoperative ambulation in gastrointestinal tumors undergoing laparoscopic surgery: a prospective multicenter clinical study

BACKGROUND

Using grip strength as a predictor of nutritional risk and early ambulation for gastrointestinal tumor surgery and determining its critical value have not been reported. This study was designed to explore the influencing factors of early postoperative ambulation ability for patients with gastrointestinal tumors who underwent laparoscopic surgery.

METHODS

Four-hundred twenty-seven patients with gastrointestinal tumors who underwent laparoscopic surgery at three tertiary A hospitals in Beijing were prospectively enrolled. Subsequently, logistic regression analysis was conducted to determine the independent predictors of early postoperative ambulation. Logistic regression analyses for the different gender were also performed. In addition, the effectiveness of preoperative grip strength measurement in nutritional risk assessment was analyzed by using nutritional risk score 2002 (NRS 2002) as a control.

RESULTS

The included cases were comprised of 283 male and 144 female patients, with an age of 59.35 ± 11.70 years. Gender, preoperative grip strength, operative time, and number of indwelling tubes were independent predictors of early postoperative ambulation. In the male group, lower preoperative grip strength and more indwelling tubes were independent risk factors for early postoperative ambulation. In the female group, lower preoperative grip strength and extended operating time were independent risk factors. Moreover, preoperative grip strength (male < 32 kg, female < 21 kg) can be used as a risk predictor for both preoperative nutritional risk and early postoperative ambulation.

CONCLUSIONS

As a simple and objective measure of muscle strength, grip strength measurement is expected to be an effective predictor for both early postoperative ambulation ability and nutritional status of patients.

The Application of Enhanced Recovery After Surgery for Gastrectomy and Colorectal Resection: A Systematic Review and Meta-Analysis

Purpose: Enhanced recovery after surgery (ERAS) protocols not only positively affect gastrointestinal surgery outcomes but may also increase the risk of some complications. This meta-analysis was conducted to assess the impact of ERAS on the recovery and complications following gastrointestinal surgery. Materials and Methods: Studies published before December 2022 were retrieved from the following databases, EMBASE, PubMed, Cochrane Library, and Web of Science, without limitations of language or race. The endpoints included lung infection, surgical site infection, postoperative ileus, length of hospitalization, urinary tract infection, readmission, anastomotic leakage, and C-reactive protein serum levels. Results: A total of 23 studies were included. The results of the meta-analysis revealed that there was a decrease in incidence of the lung infection (risk ratio = 0.46, 95% confidence interval 0.27-0.74, P = .002) and postoperative length of hospitalization (P < .00001). However, ERAS protocol groups had higher readmission rates, nausea, and vomiting. There was no significant difference in the incidence of anastomotic leakage, ileus, surgical site infection, and urinary tract infection between the experimental and control groups. Conclusions: ERAS protocols can reduce the risk of postoperative lung infections, shorten hospital stays, and expedite patient recovery. Furthermore, ERAS protocols are not associated with serious complications following gastrointestinal surgeries.

Comparison of short- and long-term outcomes between laparoscopic and open gastrectomy for locally advanced gastric cancer following neoadjuvant chemotherapy: a propensity score matching analysis

BACKGROUND

This study was performed to evaluate the safety and efficacy of laparoscopic gastrectomy (LG) in patients with locally advanced gastric cancer (LAGC) who received neoadjuvant chemotherapy (NACT).

METHODS

We retrospectively analyzed patients who underwent gastrectomy for LAGC (cT2-4aN+M0) after NACT from January 2015 to December 2019. The patients were divided into a LG group and an open gastrectomy (OG) group. The short- and long-term outcomes in both groups were examined following propensity score matching.

RESULTS

We retrospectively reviewed 288 patients with LAGC who underwent gastrectomy following NACT. Of these 288 patients, 218 were enrolled; after 1:1 propensity score matching, each group comprised 81 patients. The LG group had significantly lower estimated blood loss than the OG group [80 (50-110) vs. 280 (210-320) mL, P < 0.001) but a longer operation time [205 (186.5-222.5) vs. 182 (170-190) min, P < 0.001], a lower postoperative complication rate (24.7% vs. 42.0%, P = 0.002), and a shorter postoperative hospitalization period [8 (7-10) vs. 10 (8-11.5) days, P = 0.001]. Subgroup analysis revealed that patients who underwent laparoscopic distal gastrectomy had a lower rate of postoperative complications than patients in the OG group (18.8% vs. 38.6%, P = 0.034); however, such a pattern was not seen in patients who underwent total gastrectomy (32.3% vs. 45.9%, P = 0.251). The 3-year matched cohort analysis showed no significant difference in overall survival or recurrence-free survival (log-rank P = 0.816 and P = 0.726, respectively) (71.3% and 65.0% in OG vs. 69.1% and 61.7% in LG, respectively).

CONCLUSION

In the short term, LG following NACT is safer and more effective than OG. However, the long-term results are comparable.

Development and validation of nomograms for predicting overall survival and cancer-specific survival in elderly patients with locally advanced gastric cancer: a population-based study

OBJECTIVE

To evaluate the multiple factors influencing the survival of elderly patients with locally advanced gastric cancer (LAGC) and develop and validate the novel nomograms for predicting the survival.

METHODS

The clinical features of patients treated between 2000 and 2018 were collected and collated from the Surveillance, Epidemiology, and End Results (SEER) database and three medical centres in China, and the patients were randomly divided into a training cohort (3494), internal validation cohort (1497) and external validation cohort (841). Univariate and multivariate analyses of the prognostic values were performed to identify independent prognostic factors associated with overall survival (OS) and cancer-specific survival (CSS), and two nomogram models were developed. Harrell's concordance index (C-index) and calibration curves were employed to assess discrimination and calibration. Decision curve analysis (DCA) and receiver-operating characteristic (ROC) curves were utilized to investigate the clinical usefulness.

RESULTS

In the SEER database, the 5-year OS of the patients was 31.08%, while the 5-year CSS of the patients was 44.09%. Furthermore, in the external validation set, the 5-year OS of the patients was 49.58%, and the 5-year CSS of these patients was 53.51%. After statistical analysis, nine independent prognostic factors of OS and CSS were identified, including age, race, tumour size, differentiation, TNM stage, gastrectomy type, lymph node metastasis (LNM), lymph node ratio (LNR) and chemotherapy. The C-index (approximately 0.7) and calibration curve (close to the optimal calibration line) indicated satisfactory discrimination and calibration of the nomogram. DCA and ROC curves showed that the developed nomogram was superior to TNM stage.

CONCLUSION

The novel validated nomogram could accurately predict the prognosis of individual elderly patients with LAGC and guide the selection of clinical treatment measures.

Efficacy and safety of enhanced recovery after surgery protocol on minimally invasive bariatric surgery: a meta-analysis

BACKGROUND

Enhanced recovery after surgery (ERAS), a multidisciplinary and multimodal perioperative care protocol, has been widely used in several surgical fields. However, the effect of this care protocol on patients receiving minimally invasive bariatric surgery remains unclear. This meta-analysis compared the clinical outcomes of the ERAS protocol and standard care (SC) in patients who underwent minimally invasive bariatric surgery.

MATERIAL AND METHODS

PubMed, Web of Science, Cochrane Library, and Embase databases were systematically searched to identify literature reporting the effects of the ERAS protocol on clinical outcomes in patients undergoing minimally invasive bariatric surgery. All the articles published until 01 October 2022, were searched, followed by data extraction of the included literature and independent quality assessment. Then, pooled mean difference (MD) and odds ratio with a 95% CI were calculated by either a random-effects or fixed-effects model.

RESULTS

Overall, 21 studies involving 10 764 patients were included in the final analysis. With the ERAS protocol, the length of hospitalization (MD: -1.02, 95% CI: -1.41 to -0.64, P <0.00001), hospitalization costs (MD: -678.50, 95% CI: -1196.39 to -160.60, P =0.01), and the incidence of 30-day readmission (odds ratio =0.78, 95% CI: 0.63-0.97, P =0.02) were significantly reduced. The incidences of overall complications, major complications (Clavien-Dindo grade ≥3), postoperative nausea and vomiting, intra-abdominal bleeding, anastomotic leak, incisional infection, reoperation, and mortality did not differ significantly between the ERAS and SC groups.

CONCLUSIONS

The current meta-analysis indicated that the ERAS protocol could be safely and feasibly implemented in the perioperative management of patients receiving minimally invasive bariatric surgery. Compared with SC, this protocol leads to significantly shorter hospitalization lengths, lower 30-day readmission rate, and hospitalization costs. However, no differences were observed in postoperative complications and mortality.

Application of enhanced recovery after surgery in perioperative patients undergoing laparoscopic surgery for gastric cancer: A meta-analysis

BACKGROUND

To analyze the effect of enhanced recovery after surgery (ERAS) in perioperative patients undergoing laparoscopic surgery for gastric cancer (GC).

METHODS

We searched the literature databases of PubMed (https://pubmed.ncbi.nlm.nih.gov/) and Web of Science (https://www.webofscience.com/) for studies related to ERAS and laparoscopic surgery for GC from their inception till October 2022, and the retrieved articles were further screened for analysis. The literature quality was evaluated based on the Cochrane risk of bias tool. The endpoints included the first postoperative exhaust time, first postoperative bowel movement, length of stay, complications and hospitalization expenses. The meta-analysis was performed using RevMan 5.4 software.

RESULTS

11 studies were included, involving 2039 patients. Meta-analysis showed that the first postoperative exhaust and bowel movement were earlier and the length of stay was shorter in the experimental group (e.g.,) than in the control group (CG) (P < .05). Moreover, a lower incidence of complications and markedly reduced hospitalization expenses were determined in for example (P < .05). Due to the heterogeneity in the comparison of indicators such as the first postoperative exhaust and bowel movement across articles, a funnel plot was drawn for observations. The plot was found to be basically symmetrical, indicating small results bias and reliable reference significance of our findings.

CONCLUSION

ERAS for perioperative patients undergoing laparoscopic surgery for GC can effectively shorten the postoperative rehabilitation cycle of patients, improve surgical safety and reduce treatment costs.

The application of enhanced recovery after surgery in minimally invasive gastrectomy for gastric cancer: a meta-analysis of randomized controlled trials

OBJECTIVE

We aimed to investigate the efficacy and safety of enhanced recovery after surgery (ERAS) for patients with gastric cancer undergoing minimally invasive surgery (MIS).

METHODS

We searched the PubMed, Cochrane Library, Web of Science, Embase, CNKI, VIP, WanFang, and CBM for relevant RCTs from the database inception until December 2021, for studies that compared the ERAS and traditional care (TC) in MIS for gastric cancer.

RESULTS

A total of 25 RCTs comprising 2809 patients were included in this study. When compared with the traditional care TC group, the ERAS group had a shorter postoperative hospital stay [MD = -1.88,95%CI (-2.22, -1.55), P < 0.00001] and an earlier time at first postoperative flatus [MD = -18.12,95%CI (-21.45,-14.80), P < 0.00001] along with lower medical costs [SMD = -0.64, 95% CI (-0.85, -0.43), P < 0.00001] and an overall reduction in postoperative complication rates [RR = 0.55, 95% CI (0.44, 0.69), P < 0.00001]. However, the difference in the readmission rates    was not significant.

CONCLUSIONS

ERAS can shorten the postoperative hospital stay, hasten the first postoperative flatus and reduce medical costs and overall postoperative complication rate without increasing readmission rates. Therefore, the ERAS protocol is preferable for gastric cancer patients undergoing MIS.

Can an incomplete ERAS protocol reduce postoperative complications compared with conventional care in laparoscopic radical resection of colorectal cancer? A multicenter observational cohort and propensity score-matched analysis

Background

The patients undergoing laparoscopic radical colorectomy in many Chinese hospitals do not achieve high compliance with the ERAS (enhanced recovery programs after surgery) protocol.

Methods

The clinical data from 1,258 patients were collected and divided into the non-ERAS and incomplete ERAS groups.

Results

A total of 1,169 patients were screened for inclusion. After propensity score-matched analysis (PSM), 464 pairs of well-matched patients were generated for comparative study. Incomplete ERAS reduced the incidence of postoperative complications (p = 0.002), both mild (6.7% vs. 10.8%, p = 0.008) and severe (3.2% vs. 6.0%, p = 0.008). Statistically, incomplete ERAS reduced indirect surgical complications (27,5.8% vs. 59, 12.7) but not local complications (19,4.1% vs. 19, 4.1%). The subgroup analysis of postoperative complications revealed that all patients benefited from the incomplete ERAS protocol regardless of sex (male, p = 0.037, 11.9% vs. 17.9%; female, p = 0.010, 5.9% vs. 14.8%) or whether neoadjuvant chemotherapy was administered (neoadjuvant chemotherapy, p = 0.015, 7.4% vs. 24.5%; no neoadjuvant chemotherapy, p = 0.018, 10.2% vs. 15.8%). Younger patients (<60 year, p = 0.002, 7.6% vs. 17.5%) with a low BMI (<22.84, 9.4% vs. 21.1%, p < 0.001), smaller tumor size (<4.0 cm, 8.1% vs. 18.1%, p = 0.004), no fundamental diseases (8.8% vs. 17.0%, p = 0.007), a low ASA score (1/2, 9.7% vs. 16.3%, p = 0.004), proximal colon tumors (ascending/transverse colon, 12.2% vs. 24.3%, p = 0.027), poor (6.1% vs. 23.7%, p = 0.012)/moderate (10.3% vs. 15.3%, p = 0.034) tumor differentiation and no preoperative neoadjuvant radiotherapy (10.3% vs. 16.9%, p = 0.004) received more benefit from the incomplete ERAS protocol.

Conclusion

The incomplete ERAS protocol decreased the incidence of postoperative complications, especially among younger patients (<60 year) with a low BMI (<22.84), smaller tumor size (<4.0 cm), no fundamental diseases, low ASA score (1/2), proximal colon tumors (ascending/transverse colon), poor/moderate differentiation and no preoperative neoadjuvant radiotherapy. ERAS should be recommended to as many patients as possible, although some will not exhibit high compliance. In the future, the core elements of ERAS need to be identified to improve the protocol.

Effects of the Enhanced Recovery After Surgery (ERAS) Program for Colorectal Cancer Patients Undergoing Laparoscopic Surgery

This study sought to investigate the effects of the enhanced recovery after surgery (ERAS) program on postoperative recovery and nutritional status in patients with colorectal cancer undergoing laparoscopic surgery. A total of 37 patients were included: 19 in the experimental group and 18 in the control group. The experimental group was supplemented with carbohydrate drinks before and after surgery, and the control group was maintained with fasting and water intake in the traditional method. Both care management and nutrition education were implemented for both groups. Patients were evaluated for physical condition, clinical indicators, blood tests, pain, length of stay, nutritional status, and nutrient intake. Use of the ERAS program for the experimental group resulted in shorter length of stay (p = 0.006), less pain (p < 0.001), and a lower rate of malnutrition (p = 0.014) compared with controls. In conclusion, carbohydrate drinks provide great advantages by reducing discomfort, such as pain or thirst, during fasting in patients after colon cancer surgery, helping patients to eat comfortably and actively, minimizing insulin resistance, maintaining nitrogen balance, and reducing infection and anastomosis leakage. For use of ERAS as a standardized program, repeated and expanded research is needed, and a Korean-style ERAS should be prepared by using this approach for various diseases.

Safe Discharge Criteria After Curative Gastrectomy for Gastric Cancer

Purpose

This study aimed to investigate the relationship between clinical and laboratory parameters and complication status to predict which patients can be safely discharged from the hospital on the third postoperative day (POD).

Materials and Methods

Data from a prospectively maintained database of 2,110 consecutive patients with gastric adenocarcinoma who underwent curative surgery were reviewed. The third POD vital signs, laboratory data, and details of the course after surgery were collected. Patients with grade II or higher complications after the third POD were considered unsuitable for early discharge. The performance metrics were calculated for all algorithm parameters. The proposed algorithm was tested using a validation dataset of consecutive patients from the same center.

Results

Of 1,438 patients in the study cohort, 142 (9.9%) were considered unsuitable for early discharge. C-reactive protein level, body temperature, pulse rate, and neutrophil count had good performance metrics and were determined to be independent prognostic factors. An algorithm consisting of these 4 parameters had a negative predictive value (NPV) of 95.9% (95% confidence interval [CI], 94.2–97.3), sensitivity of 80.3% (95% CI, 72.8–86.5), and specificity of 51.1% (95% CI, 48.3–53.8). Only 28 (1.9%) patients in the study cohort were classified as false negatives. In the validation dataset, the NPV was 93.7%, sensitivity was 66%, and 3.3% (17/512) of patients were classified as false negatives.

Conclusions

Simple clinical and laboratory parameters obtained on the third POD can be used when making decisions regarding the safe early discharge of patients who underwent gastrectomy.

Immediate vs. gradual advancement to goal of enteral nutrition after elective abdominal surgery: A multicenter non-inferiority randomized trial

BACKGROUND & AIMS

The strategy of increasing the postoperative enteral nutrition dose to the target goal has not yet been clarified. This study aimed to determine whether an immediate goal-dose enteral nutrition (IGEN) strategy is non-inferior to a gradual goal-dose enteral nutrition (GGEN) strategy in reducing infections in patients undergoing abdominal surgery involving the organs of the digestive system.

METHODS

This randomized controlled trial enrolled postoperative patients with nutritional risk screening 2002 scores ≥3 from 11 Chinese hospitals. Energy targets were calculated as 25 kcal/kg and 30 kcal/kg of ideal body weight for women and men, respectively. Patients were randomly assigned 1:1 to IGEN or GGEN group after enteral tolerance was confirmed (30% of the target on day 2). The IGEN group immediately started receiving 100% of the caloric requirements on day 3, while the GGEN group received 40% progressing to 80% of target on day 7. The primary endpoint was the infection rate until discharge, based on the intention-to-treat population.

RESULTS

A total of 411 patients were enrolled and randomized to the IGEN and GGEN groups, and five patients did not receive the allocated intervention. A total of 406 patients were included in the primary analysis, with 199 and 207 in the IGEN and GGEN groups, respectively. Infection was observed in 17/199 (8.5%) in the IGEN group and 19/207 (9.2%) in the GGEN group, respectively (difference, -0.6%; [95% confidence interval (CI), -6.2%-4.9%]; P = 0.009 for non-inferiority test). There were significantly more gastrointestinal intolerance events with IGEN than with GGEN (58/199 [29.1%] vs. 32/207 [15.5%], P < 0.001). All other secondary endpoints were non-significant.

CONCLUSIONS

Among postoperative patients at nutritional risk, IGEN was non-inferior to GGEN in regards to infectious complications. IGEN was associated with more gastrointestinal intolerance events. It showed that IGEN cannot be considered to be clinically directive. ClinicalTrials.gov (#NCT03117348).
