The enhanced recovery after surgery (ERAS) pathway for patients undergoing major elective open colorectal surgery: a meta-analysis of randomized controlled trials

Efficacy of modified pancreatic duct stent drainage during endoscopic retrograde cholangiopancreatography for common bile duct stones

BACKGROUND

Common bile duct stones pose a high risk of recurrence or disease progression if not promptly treated. However, there is still no optimal treatment approach.

AIM

To investigate the clinical efficacy of modified pancreatic duct stent drainage in endoscopic retrograde cholangiopancreatography (ERCP) for treating common bile duct stones.

METHODS

This retrospective study included 175 patients with common bile duct stones treated at Taizhou Fourth People’s Hospital between January 1, 2021, and November 30, 2023. The patients were divided into three groups-the modified pancreatic duct stent drainage group (59 cases), the nasobiliary drainage group (58 cases), and the standard biliary drainage group (58 cases). Preoperative general clinical data, laboratory indicators, and the visual analog scale (VAS) at two time points (24 hours before and after surgery) were compared, along with postoperative complications across the three groups.

RESULTS

Serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, total bilirubin, direct bilirubin, C-reactive protein, and amylase were significantly lower in the modified pancreatic duct stent drainage group and the standard biliary drainage group than those in the nasobiliary drainage group (P < 0.05). However, no statistically significant differences were observed in white blood cells, hemoglobin, or neutrophil levels among the three groups (P > 0.05). The standard biliary drainage group had significantly lower VAS scores [(4.36 ± 1.18) points] than those for the modified pancreatic duct stent drainage group [(4.92 ± 1.68) points] (P = 0.033), and the nasobiliary drainage group [(5.54 ± 1.24) points] (P = 0.017). There were no statistically significant differences in complication rates across the three groups (P > 0.05).

CONCLUSION

Compared to standard biliary drainage and nasobiliary drainage, the modified pancreatic duct stent used during ERCP for patients with bile duct stones significantly reduced hepatocyte injury, improved liver function parameters, alleviated inflammation and pain, enhanced patient comfort, and demonstrated superior safety.

Perianastomotic pH Monitoring for Early Detection of Anastomotic Leaks in Gastrointestinal Surgery: A Systematic Review of the Literature

IntroductionAnastomotic leak (AL) represents a significant complication following gastrointestinal (GI) surgery, contributing to increased morbidity and mortality. pH monitoring has emerged as a potential diagnostic tool for the early detection of AL, but its effectiveness and clinical utility remain to be fully elucidated. This review aims to summarise the evidence regarding perianastomotic pH monitoring for AL detection.MethodsA systematic search of relevant databases was conducted to identify pre-clinical and clinical studies investigating pH monitoring for AL detection following GI surgery. Studies were screened by two independent reviewers based on predefined inclusion and exclusion criteria. Data were extracted and presented as a narrative synthesis.ResultsA total of 10 studies were included in the review, comprising animal studies (n = 2), and human studies in upper GI (n = 3) and colorectal (n = 5) patients. Consistent findings of lower pH values in patients with AL across various postoperative time points were demonstrated. There was diversity in the pH detection method, in addition to variable frequency and timing of pH monitoring. Four studies reported a shorter time for AL detection with pH monitoring vs conventional methods, although no statistical comparisons were used. No standard pH cut-off value for AL detection was identified.ConclusionpH monitoring shows potential as a diagnostic tool for the early detection of AL following GI surgery. While the existing evidence supports its potential utility, further research is required to establish standardised protocols and assess its clinical impact.

Enhanced recovery after surgery (ERAS) in stoma reversal surgery: a systematic review and meta-analysis

Stoma reversal surgery is known for relatively high complication rates. While Enhanced Recovery After Surgery (ERAS) protocols are extensively validated for colorectal surgery, their use in stoma reversal remains underexplored. This systematic review and meta-analysis evaluates clinical outcomes of stoma reversal surgery under ERAS protocols compared to standard care (SC) practices. Medline, EMBASE, and Cochrane Central databases were searched for studies that compared clinical outcomes of stoma reversal surgery under ERAS protocols versus SC practices. The endpoints of interest were length of stay (LOS), ileus, wound infection, anastomotic leak, time to first stool, overall, minor, and major postoperative complications, readmission rates, and reoperation rates. Mean difference (MD) was calculated for continuous variables and Odds Ratio (OR) for dichotomous variables. Statistical analysis was performed with R version 4.4.0. We included eight studies comprising 1322 patients. Among these, 603 (45.6%) followed an ERAS protocol, while 719 (54.4%) received SC practices. ERAS was associated with a significant decrease in LOS (MD -1.83; 95% CI -2.55 to -1.12; p < 0.01), wound infection (OR 0.47; 95% CI 0.23 to 0.97; p = 0.041), and time to first stool (MD -1.02; 95% CI -1.22 to -0.81; p < 0.01). No statistically significant difference was observed regarding ileus, anastomotic leak, overall, minor, and major postoperative complications, readmission rates, or reoperation rates. The implementation of ERAS protocols in stoma reversal procedures should be considered, as it was associated with a shorter length of hospital stay without increasing morbidity, and may even reduce complications such as wound infections.

Impact of postoperative complications on clinical outcomes after gastrectomy for cancer: multicentre study

BACKGROUND

To reduce the clinical and economic burden of complications after gastrectomy for gastric cancer, specific complications should be targeted to effectively allocate healthcare resources for quality improvement and preventive measures. The aim of this study was to assess the impact of complications on clinical outcomes.

METHODS

This was a retrospective multicentre study of patients who underwent (sub)total gastrectomy for gastric or junctional adenocarcinoma at 43 centres in 16 countries between 2017 and 2021. Outcomes were escalation of care, reoperation, prolonged hospital stay (greater than the 75th percentile), readmission, and 30-day mortality. Adjusted relative risks and population attributable fractions were estimated for specific complication-outcome pairs. The population attributable fraction represents the percentage reduction in the frequency of an adverse outcome if a complication could be completely prevented in the population.

RESULTS

In total, 7829 patients were included. Postoperative complications occurred in 1884 patients (24.1%). The most frequent complications were pulmonary complications (436 patients (5.6%)), anastomotic leakage (363 patients (4.6%)), and abdominal collection (301 patients (3.8%)). Anastomotic leakage, cardiac complications, and pulmonary complications had the greatest impact on 30-day mortality (population attributable fraction 26.6% (95% c.i. 14.5% to 38.6%), 18.7% (95% c.i. 9.4% to 28.0%), and 15.6% (95% c.i. 12.0% to 30.0%) respectively). Anastomotic leakage and pulmonary complications had the greatest impact on escalation of care (population attributable fraction 26.3% (95% c.i. 20.6% to 32.0%) and 18.4% (95% c.i. 11.7% to 25.2%) respectively), whereas anastomotic leakage and intra-abdominal bleeding had the greatest impact on reoperation (population attributable fraction 31.6% (95% c.i. 26.4% to 36.9%) and 8.5% (95% c.i. 5.5% to 11.5%) respectively). Most of the studied complications contributed to a prolonged hospital stay, whereas the contribution of complications to readmission did not exceed 15.9%. Subgroup analysis showed regional variation in the impact of complications.

CONCLUSION

Anastomotic leakage had the largest overall negative impact on clinical outcomes after gastrectomy for gastric adenocarcinoma. Reducing the incidence of anastomotic leakage and pulmonary complications would have the most impact on the burden of complications.

Efficacy of digital therapeutics for perioperative management in patients with lung cancer: a randomized controlled trial

BACKGROUND

Perioperative management and lung function recovery are vital for lung cancer patients. We conducted an open-label, single-center, noninferiority, randomized controlled trial in China to evaluate the efficacy of digital therapeutic (DTx)-assisted management vs. multidisciplinary management (MM) in the perioperative management of patients with lung cancer.

METHODS

From July 2022 to June 2023, 186 minimally invasive lung surgery patients were randomized, and 147 completed the study. The participants were randomly assigned a 1:1 ratio to receive DTx-assisted management (n = 72) or traditional MM (n = 75). The primary endpoint was the pulmonary function recovery rate measured by forced expiratory volume in the first second (FEV1%) 3 weeks after surgery, and the noninferiority margin was set to 4.8%. The secondary endpoints included hospital stay duration, 90-day unplanned readmission rate, symptom scores, patient management time, and patient satisfaction rate. Exploratory endpoints include factors influencing postoperative lung function recovery.

RESULTS

The lung function FEV1% recovery rate of the DTx group was not inferior to that of the MM group (87.18% ± 11.01% vs. 84.21% ± 11.75%). There were no significant differences between the two groups in terms of postoperative hospitalization duration or 90-day unplanned readmission rates. The patient management time in the DTx group was significantly shorter than that in the MM group (1.48 ± 3.22 min vs. 16.67 ± 6.41 min, P < 0.001). Patient symptom scores tended to decrease over time after discharge, and the 5 target symptoms included pain, coughing, shortness of breath, disturbed sleep, and fatigue. On the 7th day after discharge, the DTx group had a lower occurrence rate of the 5 target symptoms triggering the alert threshold compared to the MM group (P = 0.002). Patients with higher education levels achieved a better FEV1% recovery rate with DTx-assisted management (P = 0.021).

CONCLUSIONS

Compared with the MM group, the DTx group achieved noninferior results in all evaluated clinically meaningful endpoints but was significantly more efficient in perioperative management, providing an alternative digitalized management mode for patients with lung cancer surgery.

Quadratus lumborum block is feasible alternative to epidural block for postoperative analgesia after open radical cystectomy: surgical and oncological outcomes of a randomised clinical trial

OBJECTIVE

The current lack of standardised perioperative pain management protocols for open radical cystectomy (ORC) underscores the need for alternative approaches to the longstanding tradition of epidural block. The aim of this study was to assess the impact of bilateral single injection quadratum lumborum block (QLB) on patients' recovery and complication rates compared with epidural analgesia after ORC in a single-centre, randomised, parallel-group trial including adult patients with bladder cancer.

MATERIAL AND METHODS

Consecutive ORC patients were randomly allocated into QLB and the epidural group. The primary endpoint of this study was related to opioid consumption, and the results have been published earlier. This report focuses on secondary outcomes.

RESULTS

This study included a total of 41 patients, with 20 patients in the QLB group and 21 patients in the epidural group. Finally, 39 patients were included in the analysis.  There was a trend for more frequent need for postoperative norepinephrine and fluid support in the epidural group but without statistical significance. Postoperative complication rate was similar. Two patients in the epidural group compared to none in the QLB group were rehospitalised within 30 and 90 days. Mortality rate within 90 days was higher in the epidural group (4 vs. 0 patients, P = 0.064).

CONCLUSIONS

In this trial, there were no significant differences in surgical and oncological outcomes after ORC when QLB is compared with epidural block for postoperative analgesia.  Trial registration: ClinicalTrials.gov Identifier: NCT03328988.

The Impact of Enhanced Recovery After Surgery Compliance in Colorectal Surgery for Cancer

Background: This study aimed to assess the impact of Enhanced Recovery After Surgery (ERAS) compliance and to identify which components of this protocol are most likely to affect postoperative outcomes in patients undergoing colorectal cancer surgery. Methods: This is a retrospective cohort evaluating patients who underwent elective colon resection. ERAS compliance was assessed based on adherence to the protocol components. The study examined the following outcomes: postoperative complications, readmission rates, mortality, conversion to open surgery, stoma creation, and length of hospital stay. Results: Of the 410 patients studied, 59% achieved ≥75% compliance. Comparison between compliance groups (<75% versus ≥75%) showed significant differences in overall complications (P = .002), severe complications (P = .001), and length of hospital stay (P < .001). The area under the receiver operating characteristic curve for predicting the absence of severe complications based on ERAS compliance was 0.677 (95% confidence interval: 0.602-0.752). Logistic regression analyses demonstrated that ERAS compliance was significantly associated with a reduced risk of severe complications (P < .001), as well as that the following items: avoiding prophylactic drains (P < .001), minimal use of postoperative opioids (P = .045), avoidance of postoperative salt and water overload (P < .001), postoperative nutritional support (P = .048), and early mobilization (P = .025). Conclusion: High ERAS compliance is associated with improved postoperative outcomes in colorectal cancer surgery. Key protocol components for preventing severe complications include avoiding prophylactic drains, minimal postoperative opioid use, avoiding salt and water overload, nutritional support, and early mobilization.

Has the Use of Enhanced Recovery Protocols in Colorectal Surgery Increased Postoperative Bleeding Complications?

BACKGROUND

Enhanced recovery after surgery protocols are multimodal perioperative care pathways shown to improve postoperative complications and decrease the length of stay after surgery. A critical component of an enhanced recovery after surgery protocol is the use of multimodal nonopiate analgesia using nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 inhibitors.

OBJECTIVE

To compare the incidence of postoperative GI bleeding between patients treated with and without an enhanced recovery after surgery protocol.

DESIGN

Retrospective review of a prospectively maintained colorectal registry.

SETTINGS

Large colorectal referral center.

PATIENTS

Preoperative elective colorectal surgery requiring an anastomosis.

INTERVENTION

Standardized enhanced recovery after surgery protocol included celecoxib and ketorolac.

MAIN OUTCOME

Postoperative outcomes included bleeding (±sequelae), reduction in hematocrit after the operation, intervention for bleeding (transfusion, endoscopy, or surgery), length of stay, and hospital readmission.

RESULTS

The enhanced recovery after surgery group (n = 630) and nonenhanced recovery after surgery group (n = 739) were comparable in baseline clinical features except for surgical indication, with more IBD and less malignant disease in the enhanced recovery after surgery group. Minimally invasive surgery was more commonly performed in the enhanced recovery after surgery group. Both bleeding with sequelae ( p < 0.0001) and bleeding without sequelae ( p = 0.0004) were significantly more common in the enhanced recovery after surgery group compared to the nonenhanced recovery after surgery group. In addition, a significantly larger hematocrit decline after the operation was noted in the enhanced recovery after surgery group ( p < 0.0001). However, both the need for transfusion and intervention for bleeding did not significantly differ between patient groups. Factors associated with bleeding were the use of an enhanced recovery after surgery protocol (OR 2.96; 95% CI, 1.57-5.58; p < 0.001) and performing a small to large bowel anastomosis (OR 2.68; 95% CI, 1.49-4.81; p < 0.001).

LIMITATIONS

Retrospective observational design and inability to determine which component of the enhanced recovery after surgery protocol increased the risk of bleeding.

CONCLUSIONS

Use of an enhanced recovery after surgery protocol in patients undergoing colorectal surgery with an anastomosis is associated with an increased incidence of bleeding without significant difference in the need for transfusion or intervention. See Video Abstract .

EL USO DE PROTOCOLOS DE RECUPERACIN MEJORADA EN CIRUGA COLORRECTAL HA AUMENTADO LAS COMPLICACIONES HEMORRGICAS POSTOPERATORIAS

ANTECEDENTES:Los protocolos de recuperación mejorada después de la cirugía (ERAS) son vías de atención perioperatoria multimodal que han demostrado mejorar las complicaciones posoperatorias y disminuir la duración de la estancia después de la cirugía. Un componente crítico de un protocolo ERAS es el uso de analgesia multimodal no opiácea mediante fármacos antiinflamatorios no esteroideos e inhibidores de la COX-2.OBJETIVO:Comparar la incidencia de sangrado gastrointestinal posoperatorio entre pacientes tratados con y sin un protocolo ERAS.DISEÑO:Revisión retrospectiva de un registro colorrectal prospectivo mantenido.ESCENARIO:Centro de referencia colorrectal grande.PACIENTES:Cirugía colorrectal electiva preoperatoria que requiere una anastomosis.INTERVENCIÓN:El protocolo ERAS estandarizado incluyó celecoxib y ketorolaco.RESULTADO PRINCIPAL:Los resultados posoperatorios incluyeron sangrado (+/- secuelas), reducción del hematocrito después de la operación, intervención para el sangrado (transfusión, endoscopia o cirugía), duración de la estancia hospitalaria y reingreso hospitalario.RESULTADOS:El grupo ERAS (n = 630) y los grupos no ERAS (n = 739) fueron comparables en las características clínicas iniciales excepto por la indicación quirúrgica, con más enfermedad inflamatoria intestinal y menos enfermedad maligna en el grupo ERAS (Tabla 1). La cirugía mínimamente invasiva se realizó con mayor frecuencia en el grupo ERAS. Tanto el sangrado con secuelas ( p < 0,0001) como el sangrado sin secuelas ( p = 0,0004) fueron significativamente más comunes en el grupo ERAS en comparación con el grupo no ERAS. Además, se observó una disminución significativamente mayor del hematocrito después de la operación en el grupo ERAS ( p < 0,0001). Sin embargo, tanto la necesidad de transfusión como la intervención por sangrado no difirieron significativamente entre los grupos de pacientes. Los factores asociados con el sangrado fueron el uso de un protocolo ERAS (OR=2,96; IC del 95% 1,57-5,58; p < 0,001) y la realización de una anastomosis de intestino delgado a grueso (OR= 2,68; IC del 95% 1,49-4,81; p < 0,001).LIMITACIÓN:Diseño observacional retrospectivo e imposibilidad de determinar qué componente del protocolo ERAS causó el sangrado.CONCLUSIÓN:El uso de un protocolo ERAS en pacientes sometidos a cirugía colorrectal con anastomosis se asocia con una mayor incidencia de sangrado sin diferencia significativa en la necesidad de transfusión o intervención.

Improving Enhanced Recovery after Surgery (ERAS): The Effect of a Patient-Centred Mobile Application and an Activity Tracker on Patient Engagement in Colorectal Surgery

BACKGROUND

The Enhanced Recovery After Surgery (ERAS) protocol improved perioperative colorectal care. Although the protocol is firmly implemented across hospital settings, there are benefits to gain by actively involving patients in their recovery. The main objective of this study was to investigate whether compliance with selected items in the ERAS protocol could further improve by using a patient-centred mobile application.

METHOD

This multicentre, randomised controlled trial was conducted between October 2019 and September 2022. Patients aged 18 years or older who underwent elective colorectal surgery, and in possession of a smartphone were included. The intervention group used a mobile application combined with an activity tracker to be guided and supported through the ERAS pathway. The control group received standard care and wore an activity tracker to monitor their daily activities. The primary outcome was overall compliance with selected active elements of the ERAS protocol.

RESULTS

In total, 140 participants were randomised to either the intervention (n = 72) or control group (n = 68). The use of the ERAS App demonstrated a significant improvement in overall compliance by 10%, particularly in early solid food intake by 42% and early mobilization by 27%. Postoperative or patient reported outcomes did not differ between groups.

CONCLUSION

The smartphone application 'ERAS App' is able to improve adherence to the active elements of the ERAS protocol for colorectal surgery. This is an important step towards optimizing perioperative care for colorectal surgery patients and enabling patients to optimize being in control of their own recovery.

A novel artificial intelligence framework to quantify the impact of clinical compared with nonclinical influences on postoperative length of stay

BACKGROUND

The relative proportion of clinical compared with nonclinical influences on length of stay after colectomy has never been measured. We developed a novel machine-learning framework that quantifies the proportion of length of stay after colectomy attributable to clinical factors and infers the overall impact of nonclinical influences.

STUDY DESIGN

Patients who underwent partial colectomy, total colectomy, or low anterior resection included in American College of Surgeons National Surgical Quality Improvement were analyzed. Multivariable linear regression, random forest, and neural network models were developed to assess the impact of 56 clinical variables on length of stay. The random forest and neural network models were fine-tuned to maximize the explanatory power of clinical variables on length of stay. R2 measured the proportion of length of stay explained by clinical factors. The contribution of nonclinical factors was inferred from residual analysis. Mean absolute error was used to measure the discrepancy between actual and model-predicted length of stay.

RESULTS

Of 96,081 patients, 71% underwent partial colectomy (mean length of stay, 6.8 days; standard deviation, 5.6), 27% low anterior resection (5.4; 4.4), and 2% total colectomy (11.8; 7.1). Clinical factors in multivariable linear regression models accounted for only 29-54% of length of stay variability. The random forest and neural network models demonstrated persistent unexplained length of stay variability even when considering nonlinear interactions (R2: random forest [range, 0.46-0.55]; neural network [range, 0.44-0.57]), consistent with multivariable linear regression models. Mean absolute error showed clinical factors could not account for 2-2.5 days of length of stay after low anterior resection and partial colectomy, and 4 days after total colectomy.

CONCLUSION

This is the first study to quantify the overall influence of clinical factors on post-colectomy length of stay, revealing they explain less than 55% of variability. By maximizing clinical factors' explanatory impact using machine learning, the remaining variability is inferred to be nonclinical. Our findings provide hospitals with a novel paradigm to indirectly measure the influence of previously elusive nonclinical factors.

Healthcare Providers' Experiences With and Perspective on Delivering the Enhanced Recovery After Elective Caesarean Birth Pathway With Next-Day Discharge: Qualitative Analysis

AIMS

To understand the perspectives and experiences of healthcare providers who have experience working with an enhanced recovery care after elective caesarean birth pathway with next-day discharge and home midwifery.

DESIGN

This study applies a qualitative study design with a pragmatic realist approach. The realist framework was used while also taking a post-positivist philosophy.

METHODS

The work was conducted in South Australia, Australia between May and October 2019. Twenty-three semi-structured interviews were completed with 5 doctors and 18 midwives who had occupational experience working with the pathway. Interviews were analysed using following the six-phase qualitative thematic analysis process outlined by Braun and Clarke. COREQ guidelines were followed.

RESULTS

Four main themes and 11 sub-themes were identified. Main themes identified were as follows: The pathway is more than just early discharge; experiences with the process; staff engagement with the pathway; and the impact of the pathway within the health system.

CONCLUSION

Healthcare providers generally accepted the pathway and found enhanced recovery care to be a positive and beneficial model of care. Staff identified five main challenges with implementing the pathway: early discharge; eligible women's automatic inclusion on the pathway; engaging women; change for staff and organisational constraints and procedures. Elements that support integration include the following: education for women; reassurance and communication with women and families; prepared care and supports including home midwifery; staff education and communication of the evidence; clear guidelines and protocols; defined staff roles; enough clinical time and clinical flexibility.

IMPACT

Knowledge from staff in this study would be useful for other health services to consider when looking to deliver similar models of care.

PATIENT OR PUBLIC CONTRIBUTION

The health service and health providers were involved with the initiation and development of the research aims and design.

Five-year oncological outcomes after enhanced recovery after surgery (ERAS) compared to conventional care for colorectal cancer: a retrospective cohort of 981 patients

BACKGROUND

The enhanced recovery after surgery (ERAS) protocol has been introduced over the past three decades for patients undergoing colorectal surgery. However, the effect of this program on long-term survival is poorly studied. We evaluated the effect of ERAS on 5-year overall survival (OS) and recurrence-free survival (RFS) after colorectal cancer surgery, and identified risk factors.

METHODS

This retrospective study used data from the comparison of oncological outcomes at 3 years after ERAS or conventional care (pre-ERAS), conducted in our department between 2005 and 2017, and published in 2022. A total of 981 patients were included (ERAS, n = 486; pre-ERAS, n = 495).

RESULTS

The 5-year OS and RFS rates were similar in the ERAS and pre-ERAS groups, respectively (63.3% [58.9; 67.4] vs 57.7% [53.2; 61.9]; p = 0.055) and (69.5% [65.2; 73.4] vs 70.9% [66.6; 74.8]; p = 0.365). The 5-year OS result was confirmed by a propensity score analysis (HR 0.98 [0.71; 1.37], p = 0.911). Analysis of 5-year survival by a multivariate Cox model identified age (HR 1.28 [1.15; 1.43]), BMI < 18.5 (HR 1.62 [1.08; 2.45]), smoking (HR 1.68 [1.26; 2.24]), ASA score > 2 (HR 1.56 [1.22; 1.98]), and laparotomy interventions (HR 2.06 [1.61; 2.63]) as risk factors for death. Regarding RFS, multivariate analysis adjusted on the ERAS group identified age as a protective factor with a reduction of 10% in the risk of recurrence (HR 0.90 [0.81-0.99]). In contrast patients treated with neoadjuvant chemotherapy had a higher risk of recurrence (HR 1.41 [1.07-1.85]).

CONCLUSION

This study failed to demonstrate any advantage of the ERAS program in improving 5-year OS and RFS after colorectal cancer surgery. Age, undernutrition, smoking, ASA score > 2, and laparotomy interventions are independently associated with early mortality.

Improving sustainability and mitigating the environmental impact of anaesthesia and surgery along the perioperative journey: a narrative review

Climate change, environmental degradation, and biodiversity loss are adversely affecting human health and exacerbating existing inequities, intensifying pressures on already strained health systems. Paradoxically, healthcare is a high-polluting industry, responsible for 4.6% of global greenhouse gas emissions and a similar proportion of air pollutants. Perioperative services are among the most resource-intensive healthcare services and are responsible for some unique pollutants. Opportunities exist to mitigate pollution throughout the entire continuum of perioperative care, including those that occur upstream of the operating room in the process of patient selection and optimisation, delivery of anaesthesia and surgery, and the postoperative recovery period. Within a patient-centred, holistic approach, clinicians can advocate for healthy public policies that modify the determinants of surgical illness, can engage in shared decision-making to ensure appropriate clinical decisions, and can be stewards of healthcare resources. Innovation and collaboration are required to redesign clinical care pathways and processes, optimise logistical systems, and address facility emissions. The results will extend beyond the reduction of public health damages from healthcare pollution to the provision of higher value, higher quality, patient-centred care.

Review of frailty in geriatric surgical oncology

Frailty is a common phenomenon in older adult population and associated with an elevated risk of adverse health outcomes. Recent studies have demonstrated that patients with frailty undergoing surgery had a significantly higher morbidity and mortality compared to those without frailty. This is particularly important in patients with cancer because the prevalence of frailty is persistently high across a spectrum of primary cancers. Identifying frailty in oncological patients undergoing surgery may provide an important preoperative intervention opportunity to mitigate operative risks. In this review, we provide an overview of frailty and its association with other geriatric syndromes. We will also review the impact of frailty on postoperative outcomes focusing on the field of surgical oncology. We then describe currently available tools to objectively measure frailty to provide clinicians with various practical tools that may be adopted in their clinical practice. Finally, we will describe potential interventional programs, including the recently introduced Geriatric Surgery Verification program by the American College of Surgeons, that may be institutionally adopted to mitigate postoperative complications and improve meeting patient-centered goals in the frail patient population.

Consensus in ERAS protocols for ventral hernia repair: evidence-based recommendations from the ACHQC QI Committee

PURPOSE

Enhanced recovery after surgery (ERAS) protocols are widely used in the post-operative care of hernia patients. Despite their prevalence, an absence of published consensus guidelines creates significant heterogeneity in practices. The aim of this study was to evaluate elements in ERAS protocols utilized in ventral hernia repair from institutions across the United States and provide consensus recommendations for each identified element.

METHODS

Institutional members of the Abdominal Core Health Quality Collaborative (ACHQC) Quality Improvement (QI) committee submitted current ERAS protocols. Items within each protocol were classified as "elements", then assigned a topic. Any topic with ≥ 2 elements from separate institutions were labeled as a "theme," then grouped by stage in the patient care cycle. A brief review of current evidence was provided in addition to a ACHQC QI committee consensus statement.

RESULTS

A total of 295 elements from 6 tertiary referral centers specializing in hernia care were compiled into 24 themes and grouped by four separate stages: Pre-Admission Optimization, Pre-Operative Care, Intra-operative Care, and Post-Operative Management.

CONCLUSION

This article represents a multi-institutional review of ERAS protocols for ventral hernia repair and identifies common themes that may provide the framework for a unified ERAS protocol in hernia surgery. Future work may serve to develop societal guidelines defined specifically for enhanced recovery in ventral hernia repair.

Utilization of Enhanced Recovery After Surgery (ERAS) protocol in pediatric laparoscopic sleeve gastrectomy: a quality improvement project

BACKGROUND

The obesity epidemic has led to an increased number of adolescents requiring metabolic and bariatric surgery (MBS), but there is paucity of data on the impact of implementing all aspects of Enhanced Recovery After Surgery (ERAS) protocols to improve outcomes in this population.

METHODS

We implemented a comprehensive ERAS pathway for adolescents undergoing laparoscopic sleeve gastrectomy (LSG). Key elements included pre-operative fasting with carbohydrate loading in the morning of surgery, comprehensive anti-emetic and analgesic regimens including intra-operative lidocaine infusion (initiated before formal ERAS launch), regional anesthesia, and early goal-directed ambulation. We tracked opioid utilization, rescue anti-emetic use, time to oral intake, and hospital length of stay (HLOS) as outcome measures, and post-operative pain and returns to the system as balancing measures.

RESULTS

Eighty-six patients (52 patients pre-ERAS and 34 patients post-ERAS) underwent LSG with no differences in demographics. The post-ERAS group had earlier time to oral intake (3.0 vs. 5.5 h, p = 0.003), used less rescue anti-emetics, (8.0 vs. 16.0 mg, p < 0.001), and had shorter HLOS (33 vs. 54 h, p < 0.001) but no difference in opioid use (0.370 vs. 0.435 MME/kg, p = 0.17), post-operative pain scores or return to the system.

CONCLUSIONS

Our novel use of bariatric-specific ERAS protocol with intra-operative lidocaine infusion accelerates the time to goal-directed oral intake and decreases HLOS without increasing the rate of returns to the system. This study highlights the feasibility and effectiveness of adapting adult ERAS protocols to the pediatric MBS population.

Standardizing Nutritional Care for Cancer Patients: Implementation and Evaluation of a Malnutrition Risk Screening

INTRODUCTION

Cancer-related malnutrition is a highly prevalent, yet often overlooked concern in clinical practice. Although cancer-related management guidelines recommend standardized nutritional care, its implementation is scarce. The aim of this study was to investigate the prevalence of malnutrition and the medical need for nutrition counseling in cancer patients employing a novel standardized nutritional management program (containing malnutrition risk screening, nutritional assessment, and counseling). Furthermore, differences of malnutrition parameters in different cancer patient cohorts were examined.

METHODS

Cancer patients were screened for malnutrition using the Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) on the first day of their inpatient admission to the internal oncology or hematology wards. PG-SGA total score and classification into the three PG-SGA nutrition stages (A, B, C) were used to determine nutritional status. In case of a positive screening, nutritional assessment and individualized counseling by a nutritionist followed. For group comparisons, patients were divided into different groups (e.g., age, gender, tumor entity) and were evaluated accordingly.

RESULTS

A total of 1,100 inpatients were included. 56.8% of the patients had suspected or already existing malnutrition. The most common nutrition impact symptom was loss of appetite (26.7%), followed by fatigue (16.5%) and pain (16.0%). Female (p < 0.001), elderly (p < 0.001), and patients with upper gastrointestinal tract tumors (p < 0.001) showed an unfavorable nutritional status and higher need for counseling. Despite suffering from malnutrition, patients had body mass indices within the upper end of the normal range.

CONCLUSION

This study shows a high prevalence of malnutrition in hospitalized cancer patients and highlights the need for a standardized nutritional management in the clinical setting. Therefore, it is recommended to provide a malnutrition risk screening for all cancer patients and a following adequate assessment and personalized nutritional care if needed.

Perioperative care in orthognathic surgery - A systematic review and meta-analysis for enhanced recovery after surgery

The aim of this study was to determine whether implementing ERAS (Enhanced Recovery After Surgery) elements/protocols improves outcomes in orthognathic surgery (OGS) compared to conventional care. To achieve this, ERAS-specific perioperative elements were identified and literature on ERAS for OGS was systematically reviewed. Using PRISMA methodology and GRADE approach, 44 studies with 49 perioperative care elements (13 pre-, 15 intra-, 21 postoperative) were analyzed. While 39 studies focused on single elements, only five presented multimodal protocols, with three related to ERAS. Preoperative elements included antimicrobial and steroid prophylaxis and prevention of postoperative nausea and vomiting. Intraoperative aspects, especially anesthesiological, showed high evidence. Outcome parameters were heterogeneous: complications and postoperative pain were well-investigated with high evidence, while length of stay (LOS) and patient satisfaction received low to medium evidence. ICU LOS, healthcare costs, and readmission rates were underreported. The meta-analysis revealed significant results for pain reduction and trends towards fewer complications and shorter LOS in the ERAS group. Overall, ERAS protocols are not established in OMFS, particularly OGS. Further research is needed in pre- and postoperative care and standardized multimodal analgesia. The next step should be developing a comprehensive OGS protocol through a consensus conference and implementing it in clinical practice.

Psychiatric Diagnoses Are Associated With Postoperative Disparities in Patients Undergoing Major Colorectal Operations

BACKGROUND

Over 50% of hospitalized patients have comorbid psychiatric diagnoses, resulting in increased risk of morbidity such as longer lengths of stay, worse health-related quality of life, and increased mortality. However, data regarding colorectal surgery postoperative outcomes in patients with psychiatric diagnoses (PD) are limited.

METHODS

We queried a single institution's National Surgical Quality Improvement Program from 2013-2019 for major colorectal procedures. Postsurgical outcomes for patients with and without PD were compared. Primary outcomes were prolonged length of stay (pLOS) and 30-day readmission.

RESULTS

From a total of 1447 patients, 402 (27.8%) had PD. PD had more smokers (20.9% vs 15%) and higher mean body mass index (29.1 kg/m2 vs 28.2 kg/m2). Bivariate outcomes showed more surgical site infections (SSI) (10.2% vs 6.12%), reoperation (9.45% vs 6.35%), and pLOS (34.8% vs 29.0%) (all P values <.05) in the PD group. On multivariate analysis, PD had higher likelihood of reoperation (OR 1.53, 95% CI: [1.02-2.80]) and SSI (OR 1.82, 95% CI: [1.25-2.66]).

DISCUSSION

Psychiatric diagnoses are a risk factor for adverse outcomes after colorectal procedures. Further studies are needed to evaluate the benefit of perioperative mental health support services for these patients.

Enhanced recovery after surgery (ERAS) improves outcomes in elderly patients undergoing short-level lumbar fusion surgery: a retrospective study of 333 cases

BACKGROUND

Degenerative lumbar disease significantly impairs the quality of life in elderly individuals, with short-segment lumbar degenerative disease being particularly prevalent. When conservative treatment proves ineffective, surgical intervention becomes the optimal choice for managing lumbar disease. The implementation of Enhanced Recovery After Surgery (ERAS) in spinal surgery has been progressively refined, leading to greater patient benefits. However, age and the associated decline in physiological function remain critical factors influencing surgical decision-making. Currently, there is a paucity of research focused on elderly patients undergoing lumbar fusion surgery to substantiate that advanced age does not diminish the benefits derived from ERAS in this demographic.

METHODS

This is a retrospective cohort study of prospectively collected data. Patients who underwent short-segment (1 or 2 segments) transforaminal lumbar interbody fusion (TLIF) under the care of the same surgical team at our institution were recruited, and divided into no-ERAS-elder, ERAS-elder, and ERAS-younger groups. Subsequently, time to physiological function recovery and other outcomes were compared.

RESULTS

The outcomes of the ERAS-elder group (n = 113) and the no-ERAS-elder group (n = 120) were compared. The overall physiological function recovery was significantly faster (6.71 ± 2.6 days vs. 8.6 ± 2.67 days, p = 0.01) in the ERAS-elder group. Next, the outcomes of the ERAS-elder group (n = 113) were compared with those of the ERAS-younger group (n = 100), and no significant difference in total physiological function recovery was found between the two groups (6.71 ± 2.6 days vs. 6.14 ± 1.63 days, p = 0.252).

CONCLUSIONS

This study shows that the implementation of the ERAS program can effectively shorten the recovery time of physiological function in elderly patients after short-segment lumbar surgery, reduce the incidence of some complications, alleviate pain, and significantly shorten the length of hospital stay. ERAS enables elderly patients to achieve outcomes comparable to those of younger patients.

How can we reduce healthcare costs by using Enhanced Recovery After Surgery more effectively in different groups of gynaecological patients? A single-centre experience

INTRODUCTION

The objective of this study was to assess the impact of the Enhanced Recovery After Surgery (ERAS) programme implementation on treatment costs at a university-type centre, using the DRG scheme.

MATERIALS AND METHODS

Retrospective analysis of patients' data in a group of 604 individuals enroled in the study. We evaluated three groups of patients according to the ERAS clinical protocol (CP): (1) CP oncogynaecology, (2) CP simple hysterectomy, (3) CP laparoscopy. The study aimed to evaluate the impact on the length of stay (LOS), savings in bed-days, and the reduction in direct treatment costs. Three parameters-antibiotic consumption, blood derivative consumption and laboratory test costs-were chosen to compare direct treatment costs. The statistical significance of the difference in the observed parameters was tested by a two-sample unpaired t test with unequal variances at the 0.05 significance level.

RESULTS

We analysed data from 604 patients. In all three groups, the length of stay (LOS) was significantly reduced. The most significant reduction was observed in the CP oncogynaecology group, where the LOS was reduced from 11.1 days to 6.8 days (2022) and 7.6 days (2023) compared to 2019 (p < 0.05). Furthermore, there was a notable reduction in inpatient bed-days, which resulted in the capacity being made available to admit additional patients. A statistically significant reduction in direct costs was observed in the group of CP hysterectomy (antibiotic use) and in the CP laparoscopy (laboratory test costs).

CONCLUSIONS

The implementation of the ERAS principles resulted in a number of significant positive economic impacts-reduction in the LOS and a corresponding increase in bed capacity for new patients. Additionally, direct treatment costs, including those related to antibiotic use or laboratory testing were reduced. The Czech Republic's acute healthcare system, like the majority of European healthcare systems, is financed by the DRG system. This flat-rate payment per patient encourages hospital management to seek cost-reduction strategies. The results of our study indicate that fast-track protocols represent a potential viable approach to reducing the cost of treatment while simultaneously meeting the recommendations of evidence-based medicine.

Impact of an Enhanced Recovery After Surgery (ERAS) program on the management of complications after laparoscopic or robotic colectomy for cancer

PURPOSE

Enhanced Recovery After Surgery (ERAS) reduces postoperative complications (POCs) after colorectal surgery; however, its impact on the management of POCs remains unclear. This study compared the diagnosis and management of POCs before and after implementing our ERAS protocol after laparoscopic or robotic colectomy for cancer and examined the short- and mid-term oncologic impacts.

METHODS

This single-center, retrospective study evaluated all consecutive patients who underwent laparoscopic or robotic colectomy for cancer between 2012 and 2021, focusing on the incidence of POCs within 90 days. We compared outcomes before (standard group) and after (ERAS group) the implementation of our ERAS protocol in January 2016.

RESULTS

Significantly fewer patients in the ERAS group developed POCs (standard vs. ERAS, 136 of 380 patients [35.8%] vs.136 of 660 patients [20.6%]; P<0.01). The ERAS group had a significantly shorter mean total length of stay after POCs (13.1 days vs. 11.4 days, P=0.04), and the rates of life-threatening complications (6.7% vs. 0.7%) and 1-year mortality (7.4% vs. 1.5%) were significantly lower in the ERAS group than in the standard group. Among patients with anastomotic complications, laparoscopic reoperation was significantly more common in the ERAS group than in the standard group (8.3% vs. 75.0%, P<0.01). Among patients with postoperative ileus, the diagnosis and recovery times were significantly shorter in the ERAS group than in the standard group, resulting in a shorter total length of stay (13.5 days vs. 10 days, P<0.01).

CONCLUSION

The implementation of an ERAS protocol did not eliminate all POCs, but it did accelerate their diagnosis and management and improved patient outcomes.

Challenges in Enhanced Recovery After Surgery (ERAS) research

Despite the general agreement that implementation of Enhanced Recovery After Surgery (ERAS) pathways decrease hospital length of stay, a continuous challenge that has often been neglected is a procedure- and patient-specific approach. For example, asking 'Why is the patient still in hospital?' is the original premise for ERAS. Outcomes improve with increased compliance with recommended elements, but overcomplication of pathways can lead to cherry picking of elements that are convenient, resulting in 'partial ERAS'. As there are few high-quality randomised clinical trials (RCTs) that evaluate the specific role of individual preoperative, intraoperative, and postoperative elements, challenges lie ahead to identify essential ERAS elements to facilitate more widespread implementation. To achieve this goal, the balance between large RCTs and smaller detailed hypothesis-generating observational studies needs to be addressed in order to enhance knowledge and limit waste of research resources.

An investigation on the compliance of perioperative practices using ERAS protocols and barriers to the implementation of the ERAS protocols in colorectal surgery

BACKGROUND

Although ERAS protocols have many benefits, there are some deficiencies in their understanding and implementation by healthcare professionals. The present study was conducted to investigate the compliance of the current perioperative practices of healthcare professional with the ERAS protocols and to assess barriers to the implementation of ERAS protocols in colorectal surgery.

METHODS

This cross-sectional descriptive study conducted in the surgical clinics and operating rooms of a training and research hospital between January 2020 and September 2020 included 110 physician and nurse members of surgical teams. Data were collected using the Questionnaire for Evaluating the Use of the ERAS Protocol and Identifying Barriers to Implementation in Colorectal Surgery.

RESULTS

The compliance of the current perioperative practices by healthcare professionals with the ERAS protocols ranged between 15.5% (routinely leaving nasogastric tubes in situ following colorectal resection) and 61.8% (being aware of the concept of balanced analgesia). Variables such as the healthcare professional's profession, title, years in practice and colorectal surgery experience led to a difference between them in terms of their compliance of the practices with the ERAS protocols (p < 0.05). Based on the healthcare professionals' comments about barriers to the implementation of the ERAS protocol, themes such as education, teamwork, communication and lack of resources were created.

CONCLUSION

Healthcare professionals' compliance level of the current perioperative practices with the ERAS protocols was mostly low. Barriers to the implementation of the ERAS protocols had a multi-factor structure that concerns the multidisciplinary team.

Surgical outcomes in surgical oncology patients who participated in a family involvement program

BACKGROUND

There is a lack of evidence regarding the relationship between family involvement and outcomes in gastrointestinal oncology patients after surgery. To evaluate the effect of a family involvement program for patients undergoing oncologic gastrointestinal surgery on unplanned readmissions within 30 days after surgery.

METHODS

A multicenter patient-preference cohort study compared 2 groups: patients who participated in the family involvement program versus usual care. The program comprised involvement of family caregivers in care and training of health care professionals in family-centered care. Multivariable regression analyses were used to evaluate the effect of the FIP on the number of unplanned readmissions up to 30 days after surgery. Secondary outcomes included complications sensitive to fundamental care activities, emergency department visits, intensive care unit admissions, hospital length of stay, and the need for professional home care after discharge.

RESULTS

Of the 301 patients included, 152 chose the family involvement program, and 149 chose usual care. Postoperative readmissions occurred in 25 (16.4%) patients in the family involvement program group, and 15 (10.1%) in the usual care group (P = .11). A significant reduction of 16.2% was observed in the need for professional home care after discharge in the family involvement program group (P < .01). No significant differences were found between the 2 groups in the other secondary outcomes.

CONCLUSION

The family involvement program did not reduce the number of unplanned readmissions, but it led to a substantial reduction in-home care, which suggests an economic benefit from a societal perspective. Implementation of the family involvement program should, therefore, be considered in clinical practice.

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.

Contemporary Perioperative Nutritional Care

Over the last decades, surgical complication rates have fallen drastically. With the introduction of new surgical techniques coupled with specific evidence-based perioperative care protocols, patients today run half the risk of complications compared with traditional care. Many patients who in previous years needed weeks of hospital care now recover and can leave in days. These remarkable improvements are achieved by using nutritional stress-reducing care elements for the surgical patient that reduce metabolic stress and allow for the return of gut function. This new approach to nutritional care and how it is delivered as an integral part of enhancing recovery after surgery are outlined in this review. We also summarize the new and increased understanding of the effects of the routes of delivering nutrition and the role of the gut, as well as the current recommendations for artificial nutritional support.

The Role of Minimally Invasive Surgery in the Management of Inflammatory Bowel Disease: Current Trends and Future Directions

Minimally invasive surgery (MIS) provides superior results in the surgical treatment of inflammatory bowel disease (IBD). There exist various minimally invasive procedures, each possessing its own set of benefits and drawbacks. This literature review outlines these methodologies and underscores their importance in enhancing the outcomes of patients with IBD. A grand total of 192 studies were carefully chosen and succinctly summarized. Conventional multiport laparoscopy is the most widely used MIS for IBD, with single-incision laparoscopy showing even better results. Robotic surgery offers comparable results but at higher costs and longer operation times. In the future, there will be widespread acceptance of single-incision laparoscopy and robotic surgery due to improved training and reduced expenses. Further research into the technology's utility in different IBD presentations could increase its usage.

The application of ERAS in pilonidal sinus: comparison of postoperative recovery between primary suture and Limberg flap procedure in a multicenter prospective randomized trial

Purpose

We evaluated the clinical effect of utilizing a Limberg rhomboid flap graft in conjunction with Enhanced Recovery After Surgery (ERAS) protocols for the management of pilonidal sinus in the sacrococcygeal region to demonstrate the feasibility of applying ERAS to the treatment of pilonidal sinus.

Methods

Between January 2010 and August 2018, prospective data analysis was undertaken on 109 patients who received surgical treatment for pilonidal sinus in the sacrococcygeal region at the Department of Colorectal and Anal Surgery, Jingzhou Hospital affiliated to Yangtze University, and Taizhou Affiliated Hospital of Nanjing University of Chinese Medicine. The patients were randomly separated into two groups based onoperation technique: the control group (pilonidal sinus resection with primary suture) and the observation group (pilonidal sinus resection with Limberg flap graft). Some patients in the above two groups received ERAS after surgery, which included early feeding and early ambulation, etc. Therefore, we further subdivided each group into group A (without ERAS) and group B (with ERAS) according to whether they received ERAS. Comparative analysis was conducted to assess differences in pertinent data before and after surgery across the respective groups.

Results

The length of postoperative hospitalization was shorter and wound dehiscence was more common in control group B than in control group A [(9.00 ± 1.20) vs. (11.07 ± 1.78), 26.7% (8/30) vs. 7.1% (2/28), P < 0.05]. Observation group B exhibited significantly shorter wound recovery periods and postoperative hospital stays compared to observation group A [(8.08 ± 1.20) vs. (9.16 ± 2.21), (26.23 ± 3.97) vs. (29.08 ± 4.74), P < 0.05]. The hospitalization duration and wound healing time in observation group B were notably shorter than those observed in control group B [(8.08 ± 1.20) vs. (9.00 ± 1.20), [26.23 ± 3.97 vs. (43.67 ± 7.26), P < 0.05], but the operation time was longer and scar acceptance was lower [(78.85 ± 10.16) vs. (43.30 ± 6.06), (4.00 ± 0.69) vs. (7.53 ± 0.86), P < 0.05]. The VAS score, infection rate, wound dehiscence rate, subcutaneous hematoma rate and 5-year recurrence rate in observation group B were lower than those in control group B [(5.00 ± 1.39) vs. (7.13 ± 0.78), 3.8% (1/26) vs. 23.3% (7/30), 3.8% (1/26) vs. 26.7% (8/30), 3.8% (1/26) vs. 26.7%(8/30), 7.7% (2/26) vs. 30.0% (9/30), P < 0.05], but the rate of flap ischemia or necrosis was higher [15.4% (4/26) vs. 0(0/30), P < 0.05].

Conclusion

The combination of ERAS with pilonidal sinus resection using Limberg flap graft demonstrated a reduction in infection rates, wound dehiscence, subcutaneous hematoma occurrence, and recurrence rates, along with alleviation of postoperative pain and acceleration of healing time. Comparatively, this approach offers superior advantages over pilonidal sinus resection with primary suture in the management of sacrococcygeal pilonidal sinus.

Association of the TyG index with prognosis in surgical intensive care patients: data from the MIMIC-IV

BACKGROUND

The triglyceride-glucose (TyG) index, a tool for assessing insulin resistance, is increasingly recognized for its ability to predict cardiovascular and metabolic risks. However, its relationship with trauma and surgical patient prognosis is understudied. This study investigated the correlation between the TyG index and mortality risk in surgical/trauma ICU patients to identify high-risk individuals and improve prognostic strategies.

METHODS

This study identified patients requiring trauma/surgical ICU admission from the Medical Information Mart for Intensive Care (MIMIC-IV) database, and divided them into tertiles based on the TyG index. The outcomes included 28-day mortality and 180-day mortality for short-term and long-term prognosis. The associations between the TyG index and clinical outcomes in patients were elucidated using Cox proportional hazards regression analysis and RCS models.

RESULTS

A total of 2103 patients were enrolled. The 28-day mortality and 180-day mortality rates reached 18% and 24%, respectively. Multivariate Cox proportional hazards analysis revealed that an elevated TyG index was significantly related to 28-day and 180-day mortality after covariates adjusting. An elevated TyG index was significantly associated with 28-day mortality (adjusted hazard ratio, 1.19; 95% confidence interval 1.04-1.37) and 180-day mortality (adjusted hazard ratio, 1.24; 95% confidence interval 1.11-1.39). RCS models revealed that a progressively increasing risk of mortality was related to an elevated TyG index. According to our subgroup analysis, an elevated TyG index is associated with increased risk of 28-day and 180-day mortality in critically ill patients younger than 60 years old, as well as those with concomitant stroke or cardiovascular diseases. Additionally, in nondiabetic patients, an elevated TyG index is associated with 180-day mortality.

CONCLUSION

An increasing risk of mortality was related to an elevated TyG index. In critically ill patients younger than 60 years old, as well as those with concomitant stroke or cardiovascular diseases, an elevated TyG index is associated with adverse short-term and long-term outcomes. Furthermore, in non-diabetic patients, an elevated TyG index is associated with adverse long-term prognosis.

Enhanced Recovery After Surgery Guidelines and Hospital Length of Stay, Readmission, Complications, and Mortality: A Meta-Analysis of Randomized Clinical Trials

Importance

A comprehensive review of the evidence exploring the outcomes of enhanced recovery after surgery (ERAS) guidelines has not been completed.

Objective

To evaluate if ERAS guidelines are associated with improved hospital length of stay, hospital readmission, complications, and mortality compared with usual surgical care, and to understand differences in estimates based on study and patient factors.

Data Sources

MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central were searched from inception until June 2021.

Study Selection

Titles, abstracts, and full-text articles were screened by 2 independent reviewers. Eligible studies were randomized clinical trials that examined ERAS-guided surgery compared with a control group and reported on at least 1 of the outcomes.

Data Extraction and Synthesis

Data were abstracted in duplicate using a standardized data abstraction form. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias tool. Random-effects meta-analysis was used to pool estimates for each outcome, and meta-regression identified sources of heterogeneity within each outcome.

Main Outcome and Measures

The primary outcomes were hospital length of stay, hospital readmission within 30 days of index discharge, 30-day postoperative complications, and 30-day postoperative mortality.

Results

Of the 12 047 references identified, 1493 full texts were screened for eligibility, 495 were included in the systematic review, and 74 RCTs with 9076 participants were included in the meta-analysis. Included studies presented data from 21 countries and 9 ERAS-guided surgical procedures with 15 (20.3%) having a low risk of bias. The mean (SD) Reporting on ERAS Compliance, Outcomes, and Elements Research checklist score was 13.5 (2.3). Hospital length of stay decreased by 1.88 days (95% CI, 0.95-2.81 days; I2 = 86.5%; P < .001) and the risk of complications decreased (risk ratio, 0.71; 95% CI, 0.59-0.87; I2 = 78.6%; P < .001) in the ERAS group. Risk of readmission and mortality were not significant.

Conclusions and Relevance

In this meta-analysis, ERAS guidelines were associated with decreased hospital length of stay and complications. Future studies should aim to improve implementation of ERAS and increase the reach of the guidelines.

Clinical Impact of an Enhanced Recovery Program for Lower-extremity Bypass

OBJECTIVE

To determine the association of Enhanced Recovery Program (ERP) implementation with length of stay (LOS) and perioperative outcomes after lower-extremity bypass (LEB).

BACKGROUND

ERPs have been shown to decrease hospital LOS and improve perioperative outcomes, but their impact on patients undergoing vascular surgery remains unknown.

METHODS

Patients undergoing LEB who received or did not receive care under the ERP were included; pre-ERP (January 1, 2016-May 13, 2018) and ERP (May 14, 2018-July 31, 2022). Clinicopathologic characteristics and perioperative outcomes were analyzed.

RESULTS

Of 393 patients who underwent LEB [pre-ERP: n = 161 (41%); ERP: n = 232 (59%)], most were males (n = 254, 64.6%), White (n = 236, 60%), and government-insured (n = 265, 67.4%). Pre-ERP patients had higher Body Mass Index (28.8 ± 6.0 vs 27.4 ± 5.7, P = 0.03) and rates of diabetes (52% vs 36%, P = 0.002). ERP patients had a shorter total [6 (3-13) vs 7 (5-14) days, P = 0.01) and postoperative LOS [5 (3-8) vs 6 (4-8) days, P < 0.001]. Stratified by indication, postoperative LOS was shorter in ERP patients with claudication (3 vs 5 days, P = 0.01), rest pain (5 vs 6 days, P = 0.02), and tissue loss (6 vs 7 days, P = 0.03). ERP patients with rest pain also had a shorter total LOS (6 vs 7 days, P = 0.04) and lower 30-day readmission rates (32%-17%, P = 0.02). After ERP implementation, the average daily oral morphine equivalents decreased [median (interquartile range): 52.5 (26.6-105.0) vs 44.12 (22.2-74.4), P = 0.019], while the rates of direct discharge to home increased (83% vs 69%, P = 0.002).

CONCLUSIONS

This is the largest single-center cohort study evaluating ERP in LEB, showing that ERP implementation is associated with shorter LOS and improved perioperative outcomes.

Improved Postoperative Pain Management Outcomes After Implementation of Enhanced Recovery After Surgery (ERAS) Protocol for Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS-HIPEC)

BACKGROUND

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for patients with peritoneal carcinomatosis is promising but has potential for significant morbidity and prolonged hospitalization. Enhanced Recovery After Surgery (ERAS) is a standardized protocol designed to optimize perioperative care. This study describes trends in epidural and opioid use after implementing ERAS for CRS-HIPEC at a tertiary academic center.

METHODS

A retrospective analysis of patients undergoing CRS-HIPEC from January 2020 to September 2023 was conducted. ERAS was implemented in February 2022. Medication and outcomes data were compared before and after ERAS initiation. All opioids were converted to morphine milligram equivalents (MMEs).

RESULTS

A total of 136 patients underwent CRS-HIPEC: 73 (54%) pre- and 63 (46%) post-ERAS. Epidural usage increased from 63% pre-ERAS to 87% post-ERAS (p = 0.001). Compared with those without epidurals, patients with epidurals had decreased total 7-day oral and intravenous (IV) opioid requirements (45 MME vs. 316 MME; p < 0.001). There was no difference in 7-day opioid totals between pre- and post-ERAS groups. After ERAS, more patients achieved early ambulation (83% vs. 53%; p < 0.001), early diet initiation (81% vs. 25%; p < 0.001), and early return of bowel function (86% vs. 67%; p = 0.012).

CONCLUSIONS

ERAS implementation for CRS-HIPEC was associated with increased epidural use, decreased oral and IV opioid use, and earlier bowel function return. Our study demonstrates that epidural analgesia provides adequate pain control while significantly decreasing oral and IV opioid use, which may promote gastrointestinal recovery postoperatively. These findings support the implementation of an ERAS protocol for effective pain management in patients undergoing CRS-HIPEC.

Outcomes before and after Implementation of the ERAS (Enhanced Recovery after Surgery) Protocol in Open and Laparoscopic Colorectal Surgery: A Comparative Real-World Study from Northern Italy

Enhanced Recovery After Surgery (ERAS) protocols have changed perioperative care, aiming to optimize patient outcomes. This study assesses ERAS implementation effects on postoperative complications, length of hospital stay (LOS), and mortality in colorectal cancer (CRC) patients. A retrospective real-world analysis was conducted on CRC patients undergoing surgery within a Northern Italian Cancer Registry. Outcomes including complications, re-surgeries, 30-day readmission, mortality, and LOS were assessed in 2023, the year of ERAS protocol adoption, and compared with data from 2022. A total of 158 surgeries were performed, 77 cases in 2022 and 81 in 2023. In 2023, a lower incidence of postoperative complications was observed compared to that in 2022 (17.3% vs. 22.1%), despite treating a higher proportion of patients with unfavorable prognoses. However, rates of reoperations and readmissions within 30 days post-surgery increased in 2023. Mortality within 30 days remained consistent between the two groups. Patients diagnosed in 2023 experienced a statistically significant reduction in LOS compared to those in 2022 (mean: 5 vs. 8.1 days). ERAS protocols in CRC surgery yield reduced postoperative complications and shorter hospital stays, even in complex cases. Our study emphasizes ERAS' role in enhancing surgical outcomes and recovery.

Implementation of an enhanced recovery after surgery protocol for colorectal cancer in a regional hospital network supported by audit and feedback: a stepped wedge, cluster randomised trial

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols are known to potentially improve the management and outcomes of patients undergoing colorectal surgery, with limited evidence of their implementation in hospital networks and in a large population. We aimed to assess the impact of the implementation of an ERAS protocol in colorectal cancer surgery in the entire region of Piemonte, Italy, supported by an audit and feedback (A&F) intervention.

METHODS

A large, stepped wedge, cluster randomised trial enrolled patients scheduled for elective surgery at 29 general surgery units (clusters). At baseline (first 3 months), standard care was continued in all units. Thereafter, four groups of clusters began to adopt the ERAS protocol successively. By the end of the study, each cluster had a period in which standard care was maintained (control) and a period in which the protocol was applied (experimental). ERAS implementation was supported by initial training and A&F initiatives. The primary endpoint was length of stay (LOS) without outliers (>94th percentile), and the secondary endpoints were outliers for LOS, postoperative medical and surgical complications, quality of recovery and compliance with ERAS items.

RESULTS

Of 2626 randomised patients, 2397 were included in the LOS analysis (1060 in the control period and 1337 in the experimental period). The mean LOS without outliers was 8.5 days during the control period (SD 3.9) and 7.5 (SD 3.5) during the experimental one. The adjusted difference between the two periods was a reduction of -0.58 days (95% CI -1.07, -0.09; p=0.021). The compliance with ERAS items increased from 52.4% to 67.3% (estimated absolute difference +13%; 95% CI 11.4%, 14.7%). No difference in the occurrence of complications was evidenced (OR 1.22; 95% CI 0.89, 1.68).

CONCLUSION

Implementation of the ERAS protocol for colorectal cancer, supported by A&F approach, led to a substantial improvement in compliance and a reduction in LOS, without meaningful effects on complications. Trial registration number NCT04037787.

Early non compliance to enhanced recovery pathway might be an alert for underlying complications following colon surgery

PURPOSE

Early non compliance to postoperative ERAS pathway has been reported in 20-30% of patients who underwent elective colon surgery. The aim of the present study is to investigate the possible relationship between early non compliance and postoperative complications.

METHODS

We reviewed a prospective database including 1391 consecutively collected patients undergoing elective colon surgery in 22 Italian hospitals between January 2017 and June 2020. Early compliance to ERAS protocol was assessed on postoperative day (POD) 2. Failure of oral feeding, urinary catheter removal, intravenous fluids stop, and adequate mobilization were indicators of non compliance. Postoperative follow-up was carried out for 30 days after hospital discharge. The association among early postoperative ERAS compliance and the occurrence of complications was assessed with uni- and multivariate analysis.

RESULTS

A total of 1089 (78.3%) patients had malignancy and minimally invasive surgery was successfully performed in 1174 (84.3%) patients. Postoperative morbidity occurred in 403 (29.0%) patients. At multivariate analysis, male gender, open surgery, and each of the four non compliance indicators on POD 2 were significantly associated to postoperative complications. Morbidity progressively increased from 16.8% in patients with full compliance to ERAS protocol to 47.2% in patients with two non compliance indicators and 69.2% in patients with all four indicators (p < 0.001).

CONCLUSIONS

Early non compliance to ERAS protocol was significantly associated with postoperative morbidity.

Evolution of laparoscopic ileal pouch-anal anastomosis: impact of enhanced recovery program, medication changes, and staged approaches on outcomes

BACKGROUND

Although laparoscopic Ileal pouch-anal anastomosis (IPAA) has become the gold standard in restorative proctocolectomy, surgical techniques have experienced minimal changes. In contrast, substantial shifts in perioperative care, marked by the enhanced recovery program (ERP), modifications in steroid use, and a shift to a 3-staged approach, have taken center stage.

METHODS

Data extracted from our prospective IPAA database focused on the first 100 laparoscopic IPAA cases (historic group) and the latest 100 cases (modern group), aiming to measure the effect of these evolutions on postoperative outcomes.

RESULTS

The historic IPAA group had more 2-staged procedures (92% proctocolectomy), whereas the modern group had a higher number of 3-staged procedures (86% proctectomy) (P < .001). Compared with patients in the modern group, patients in the historic group were more likely to be on steroids (5% vs 67%, respectively; P < .001) or immunomodulators (0% vs 31%, respectively; P < .001) at surgery. Compared with the historic group, the modern group had a shorter operative time (335.5 ± 78.4 vs 233.8 ± 81.6, respectively; P < .001) and length of stay (LOS; 5.4 ± 3.1 vs 4.2 ± 1.6 days, respectively; P < .001). Compared with the modern group, the historic group exhibited a higher 30-day morbidity rate (20% vs 33%, respectively; P = .04) and an elevated 30-day readmission rate (9% vs 21%, respectively; P = .02). Preoperative steroids use increased complications (odds ratio [OR], 3.4; P = .01), whereas 3-staged IPAA reduced complications (OR, 0.3; P = .03). ERP was identified as a factor that predicted shorter stays.

CONCLUSION

Although ERP effectively reduced the LOS in IPAA surgery, it failed to reduce complications. Conversely, adopting a 3-staged IPAA approach proved beneficial in reducing morbidity, whereas preoperative steroid use increased complications.

Postoperative cognitive dysfunction in elderly patients with colorectal cancer: A randomized controlled study comparing goal-directed and conventional fluid therapy

To investigate the impact of goal-directed fluid therapy (GDFT) on postoperative cognitive dysfunction (POCD) in elderly patients with colorectal cancer, we conducted a randomized controlled trial. Eighty elderly patients who underwent elective laparoscopic radical resection of colorectal cancer were randomly assigned to either the GDFT group or the conventional fluid therapy group. The primary outcome was the incidence of POCD during the initial 7 postoperative days, while secondary outcomes included inflammatory marker levels such as interleukin-6 (IL-6) and S100β protein, hemodynamics, level of lactic acid, postoperative functional recovery, and complications. Among 88 randomized patients, 80 were evaluable for the primary outcome. The incidence of POCD was significantly lower in the GDFT group (15.0%) compared to the conventional fluid therapy group (30.0%), with the highest occurrence observed on day 3 postoperatively in both groups (P < 0.05). IL-6 and S100β concentrations were consistently lower in the GDFT group than in the conventional fluid therapy group at the corresponding time points (P < 0.05). The GDFT group exhibited more stable perioperative hemodynamics and lower lactate levels (P < 0.05). Moreover, patients in the GDFT group exhibited better postoperative functional recovery indicators and a lower incidence of postoperative complications (P < 0.05). In summary, GDFT appears to reduce the incidence of early POCD, accelerate postoperative recovery, and enhance overall prognosis.

Association of adherence to the enhanced recovery after surgery pathway and outcomes after laparoscopic total gastrectomy

OBJECTIVE

The current study used a composite outcome to investigate whether applying the ERAS protocol would enhance the recovery of patients undergoing laparoscopic total gastrectomy (LTG).

EXPOSURES

Laparoscopic total gastrectomy and perioperative interventions were the exposure. An ERAS clinical pathway consisting of 14 items was implemented and assessed. Patients were divided into either ERAS-compliant or non-ERAS-compliant group according the adherence above 9/14 or not.

MAIN OUTCOMES AND MEASURES

The primary study outcome was a composite outcome called 'optimal postoperative recovery' with the definition as below: discharge within 6 days with no sever complications and no unplanned re-operation or readmission within 30 days postoperatively. Univariate logistic regression analysis and multivariate logistic regression analysis were used to model optimal postoperative recovery and compliance, adjusting for patient-related and disease-related characteristics.

RESULTS

A total of 252 patients were included in this retrospective study, 129 in the ERAS compliant group and 123 in the non-ERAS-compliant group. Of these, 79.07% of the patients in ERAS compliant group achieved optimal postoperative recovery, whereas 61.79% of patients in non-ERAS-compliant group did (P = 0.0026). The incidence of sever complications was lower in the ERAS-compliant group (1.55% vs. 6.5%, P = 0.0441). No patients in ERAS compliant group had unplanned re-operation, whereas 5.69% (7/123) of patients in non-ERAS-compliant group had (p = 0.006). The median length of the postoperative hospital stay was shorter in the in the ERAS compliant group (5.51 vs. 5.68 days, P = 0.01). Both logistic (OR 2.01, 95% CI 1.21-3.34) and stepwise regression (OR 2.07, 95% CI 1.25-3.41) analysis showed that high overall compliance with the ERAS protocol facilitated optimal recovery in such patients. In bivariate analysis of compliance for patients who had an optimal postoperative recovery, carbohydrate drinks (p = 0.0196), early oral feeding (P = 0.0043), early mobilization (P = 0.0340), and restrictive intravenous fluid administration (P < 0.0001) were significantly associated with optimal postoperative recovery.

CONCLUSIONS AND RELEVANCE

Patients with higher ERAS compliance (almost 70% of the accomplishment) suffered less severe postoperative complications and were more likely to achieve optimal postoperative recovery.

Enhanced Recovery After Surgery (ERAS) Reduces Hospital Costs and Length of Hospital Stay in Radical Cystectomy: A Prospective Randomized Controlled Study

Enhanced recovery after surgery (ERAS) protocols challenge the conventional and rigid methods of surgery and anesthesia and bring about novel changes that are quite drastic. The core principle of the protocol is to minimize the metabolic disturbance caused by surgical injury, facilitate the restoration of functions in a brief period, and promote the resumption of normal activity at the earliest. To compare the outcomes of ERAS and standard protocol for patients who have undergone radical cystectomy (RC) with ileal conduit urinary diversion. This prospective randomized controlled study was performed between 2015 and 2023. The 77 patients were divided into two groups ERAS (n=39) and Standard (n=38) by sequential randomization. These two groups are divided according to protocols of bowel preparation, anesthesia, and postoperative nutrition. The clinical and demographic characteristics of the patients, and the American Society of Anesthesiologists (ASA) and Eastern Cooperative Oncology Group (ECOG) scores were recorded. Perioperative findings, the degree of complications according to the Clavien-Dindo classification, and the total cost of treatment were recorded and analyzed. Length of hospital stay (18.82±9.25 day vs 27.34±15.05 day), and cost of treatment (2168,2±933$ 2879±1806$) were higher in the standard group. The rate of nausea and vomiting and the use of antiemetics were higher in the ERAS group compared to the standard group. In patients undergoing RC, the ERAS protocol was found to shorten the duration of hospitalization and reduce the total cost of hospital stay.

Single-shot liposomal bupivacaine in place of rectus sheath catheters to provide non-opiate analgesia after laparotomy: a quality improvement project to reduce the need for ongoing nursing input

Opioid-sparing pain management is an integral component of enhanced recovery after colonic and rectal surgery. In our hospital, rectus sheath catheters (RSCs) are routinely placed during emergency laparotomy for colorectal procedures to allow a postoperative compartmental block of the surgical site with repeated doses of bupivacaine. However, RSCs require a significant amount of clinical nursing time to maintain and 'top-up'. We present a quality improvement project in which we administered single-shot liposomal bupivacaine (LB) intraoperatively as an alternative to bolus doses of conventional bupivacaine delivered through RSCs. Having thereby reduced the demands placed on nursing time through a reduction in the use of RSCs, we sought to establish whether there was any associated change in analgesic efficacy. Patient pain scores, use of patient-controlled analgesia (PCA) and length of stay following surgery were analysed before and after the introduction of LB. No disruption in these outcomes was identified using statistical process control analysis. A direct comparison of results for patients who received LB versus those who received bolus dosing of bupivacaine via RSCs found no significant differences, with a median total PCA dose of 270 mg oral morphine equivalents (OME) for patients who received LB versus 396 mg OME for patients who had RSCs (p=0.54). The median length of stay for patients who received LB was 15.5 days versus 16 days for those who had RSCs (p=0.87). We conclude that LB represents a viable alternative to boluses of conventional bupivacaine via RSCs in promoting enhanced recovery after emergency laparotomy and look to extend its use locally.

Short-term hypercaloric carbohydrate loading increases surgical stress resilience by inducing FGF21

Dietary restriction promotes resistance to surgical stress in multiple organisms. Counterintuitively, current medical protocols recommend short-term carbohydrate-rich drinks (carbohydrate loading) prior to surgery, part of a multimodal perioperative care pathway designed to enhance surgical recovery. Despite widespread clinical use, preclinical and mechanistic studies on carbohydrate loading in surgical contexts are lacking. Here we demonstrate in ad libitum-fed mice that liquid carbohydrate loading for one week drives reductions in solid food intake, while nearly doubling total caloric intake. Similarly, in humans, simple carbohydrate intake is inversely correlated with dietary protein intake. Carbohydrate loading-induced protein dilution increases expression of hepatic fibroblast growth factor 21 (FGF21) independent of caloric intake, resulting in protection in two models of surgical stress: renal and hepatic ischemia-reperfusion injury. The protection is consistent across male, female, and aged mice. In vivo, amino acid add-back or genetic FGF21 deletion blocks carbohydrate loading-mediated protection from ischemia-reperfusion injury. Finally, carbohydrate loading induction of FGF21 is associated with the induction of the canonical integrated stress response (ATF3/4, NF-kB), and oxidative metabolism (PPARγ). Together, these data support carbohydrate loading drinks prior to surgery and reveal an essential role of protein dilution via FGF21.

RESIDUAL GASTRIC VOLUME IN MORBIDLY OBESE DIABETICS AFTER AN OVERNIGHT FASTING OR 3 HOURS OF A CARBOHYDRATE-ENRICHED SUPPLEMENT: A RANDOMIZED CROSSOVER PILOT STUDY

BACKGROUND

To reduce the risk of regurgitation during anesthesia for elective procedures, residual gastric volumes (RGV) have traditionally been minimized by overnight fasting. Prolonged preoperative fasting presents some adverse consequences and has been abandoned for most surgical procedures, except for obese and/or diabetic patients.

AIMS

The aim of this study was to assess the RGV in morbidly obese diabetic patients after traditional or abbreviated fasting.

METHODS

This study was approved by the Ethics Committee for Research with Human Beings from the Federal University of Mato Grosso, under number 179.017/2012. This is a prospective, randomized, and crossover design study in eight morbidly obese type II diabetic patients. RGV was measured endoscopically after either traditional overnight fasting of at least 8 hours, or after abbreviated fasting of 6 hours for solids and 3 hours for a drink containing water plus 25 g (12.5%) of maltodextrin. Data were expressed as mean and range and differences were compared with paired t-tests at p<0.05.

RESULTS

The study population had a mean age of 41.5 years (28-53), weight of 135 kg (113-196), body mass index of 48.2 kg/m2 (40-62.4), and type II diabetes for 4.5 years (1-10). The RGV after abbreviated fasting was 21.5 ml (5-40) vs 26.3 ml (7-65) after traditional fasting. This difference was not significant (p=0.82).

CONCLUSIONS

Gastric emptying in morbidly obese diabetic patients is similar after either traditional or abbreviated fasting with a carbohydrate drink.

Anterior Quadratus Lumborum Block at Lateral Supra-Arcuate Ligament vs Lateral Quadratus Lumborum Block for Postoperative Analgesia after Laparoscopic Colorectal Surgery: A Randomized Controlled Trial

BACKGROUND

Quadratus lumborum block (QLB) has been found to be advantageous for laparoscopic colorectal surgery. This study hypothesized that preoperative anterior QLB at lateral supra-arcuate ligament (QLB-LSAL) would decrease postoperative opioid usage and offer improved analgesia within the context of multimodal analgesia compared with lateral QLB (LQLB) for laparoscopic colorectal surgery.

STUDY DESIGN

In this randomized controlled trial, 82 American Society of Anesthesiologists physical status I to III class colorectal cancer patients undergoing laparoscopic radical resection were enrolled and randomly assigned to receive either LQLB or QLB-LSAL (0.375% ropivacaine 0.3 mL/kg bilaterally for each group). The primary outcomes were the total intravenous morphine equivalent consumption at 24 hours postoperatively.

RESULTS

Intravenous morphine equivalent consumption at 24 hours postoperatively was significantly reduced in the QLB-LSAL group compared with that in the LQLB group with per-protocol analysis (29.2 ± 5.8 vs 40.5 ± 9.6 mg, p < 0.001) and intention-to-treat analysis (29.6 ± 6.1 vs 40.8 ± 9.5 mg, p < 0.001). Time to first patient-controlled analgesia request was notably longer in the QLB-LSAL group than that in the LQLB group (10.4 ± 3.9 vs 3.7 ± 1.5 hours, p < 0.001).

CONCLUSIONS

Preoperative bilateral ultrasound-guided QLB-LSAL reduces morphine usage and extends the duration until the first patient-controlled analgesia demand within the framework of multimodal analgesia when compared with LQLB after laparoscopic colorectal surgery.

Effectiveness of acupuncture for postoperative gastrointestinal recovery in patients undergoing thoracoscopic surgery: a prospective randomized controlled study

BACKGROUND

Postoperative gastrointestinal dysfunction (PGD) is one of the most common complications among patients who have undergone thoracic surgery. Acupuncture has long been used in traditional Chinese medicine to treat gastrointestinal diseases and has shown benefit as an alternative therapy for the management of digestive ailments. This study aimed to explore the therapeutic effectiveness of acupuncture as a means to aid postoperative recovery of gastrointestinal function in patients undergoing thoracoscopic surgery.

METHODS

In total, 112 patients aged 18-70 years undergoing thoracoscopic surgery between 15 June 2022 and 30 August 2022 were randomized into two groups. Patients in the acupuncture group (AG) first received acupuncture treatment 4 h after surgery, and treatment was repeated at 24 and 48 h. Patients in the control group (CG) did not receive any acupuncture treatment. Both groups received the same anesthetic protocol. Ultrasound-guided thoracic paravertebral block (TPVB) was performed in the paravertebral spaces between T4 and T5 with administration of 20 mL of 0.33% ropivacaine. All patients received patient-controlled intravenous analgesia (PCIA) after surgery.

RESULTS

Median time to first flatus [interquartile range] in the AG was significantly less than in the CG (23.25 [18.13, 29.75] vs 30.75 [24.13, 45.38] h, p < 0.001). Time to first fluid intake after surgery was significantly less in the AG, as compared with the CG (4 [3, 7] vs 6.5 [4.13, 10.75] h, p = 0.003). Static pain, measured by visual analog scale (VAS) score, was significantly different on the third day after surgery (p = 0.018). Dynamic pain VAS scores were lower in the AG versus CG on the first three postoperative days (p = 0.014, 0.003 and 0.041, respectively).

CONCLUSION

Addition of acupuncture appeared to improve recovery of postoperative gastrointestinal function and alleviate posteoperative pain in patients undergoing thoracoscopic surgery. Acupuncture may represent a feasible strategy for the prevention of PGD occurrence.

Enhanced recovery after surgery for liver transplantation: a review of recent literature

PURPOSE OF REVIEW

This review was created to highlight important articles from the past year related to the evolving field of enhanced recovery after surgery (ERAS) in liver transplantation that are relevant to the transplant anesthesiologist.

RECENT FINDINGS

The International Liver Transplantation Society (ILTS) recently completed a landmark project, the ERAS4OLT.org project, which culminated in 80 recommendations for ERAS in liver transplantation. These recommendations encompass management for deceased donor recipients, living donor recipients and living donors. This review highlights selected articles relevant to the perioperative management of deceased donor liver transplant recipients.

SUMMARY

Though, there are now published internationally agreed upon recommendations for ERAS topics specific to liver transplantation, there is an obvious need for further investigation into this area to provide high quality evidence to support these recommendations. It is reasonable to utilize these recommendations in ERAS protocols for individual institutions; however, more evidence is needed in several areas to confirm the effects of these protocols on short-term outcomes.

Enhanced recovery after robotic ventral hernia repair: factors associated with overnight stay in hospital

PURPOSE

Enhanced recovery after surgery (ERAS) protocols lead to reduced post-operative stay and improved outcomes after most types of abdominal surgery. Little is known about the optimal post-operative protocol after robotic ventral hernia repair (RVHR), including the potential limits of outpatient surgery. We report the results of an ERAS protocol after RVHR aiming to identify factors associated with overnight stay in hospital, as well as patient-reported pain levels in the immediate post-operative period.

METHODS

This was a prospective cohort study of consecutive patients undergoing RVHR. Patients were included in a prospective database, registering patient characteristics, operative details, pain and fatigue during the first 3 post-operative days and pre- and 30-day post-operative hernia-related quality of life, using the EuraHS questionnaire.

RESULTS

A total of 109 patients were included, of which 66 (61%) underwent incisional hernia repair. The most performed procedure was TARUP (robotic transabdominal retromuscular umbilical prosthetic hernia repair) (60.6%) followed by bilateral roboTAR (robotic transversus abdominis release) (19.3%). The mean horizontal fascial defect was 4.8 cm, and the mean duration of surgery was 141 min. In total, 78 (71.6%) patients were discharged on the day of surgery, and factors associated with overnight stay were increasing fascial defect area, longer duration of surgery, and transverse abdominis release. There was no association between post-operative pain and overnight hospital stay. The mean EuraHS score decreased significantly from 38.4 to 6.4 (P < 0.001).

CONCLUSION

An ERAS protocol after RVHR was associated with a high rate of outpatient procedures with low patient-reported pain levels.
