The impact of enhanced recovery after surgery (ERAS) on opioid consumption and postoperative pain levels in elective spine surgery

OBJECTIVE

Enhanced Recovery after Surgery (ERAS) protocols were developed to counteract the adverse effects of the surgical stress response, aiming for quicker postoperative recovery. Initially applied in abdominal surgeries, ERAS principles have extended to orthopedic spine surgery, but research in this area is still in its infancy. The current study investigated the impact of ERAS on postoperative pain and opioid consumption in elective spine surgeries.

METHODS

A single-center retrospective study of patients undergoing elective spine surgery from May 2019 to July 2020. Patients were categorized into two groups: those enrolled in the ERAS pathway and those adhering to traditional surgical protocols. Data on demographics, comorbidities, length of stay (LOS), surgical procedures, and postoperative outcomes were collected. Postoperative pain was evaluated using the Numerical Rating Scale (NRS), while opioid utilization was quantified in morphine milligram equivalents (MME). NRS and MME were averaged for each patient across all days under observation. Differences in outcomes between groups (ERAS vs. treatment as usual) were tested using the Wilcoxon rank sum test for continuous variables and Pearson's or Fisher's exact tests for categorical variables.

RESULTS

The median of patient's mean daily NRS scores for postoperative pain were not statistically significantly different between groups (median = 5.55 (ERAS) and 5.28 (non-ERAS), p=.2). Additionally, the median of patients' mean daily levels of MME were similar between groups (median = 17.24 (ERAS) and 16.44 (non-ERAS), p=.3) ERAS patients experienced notably shorter LOS (median=2 days) than their non-ERAS counterparts (median=3 days, p=.001). The effect of ERAS was moderated by whether the patient had ACDF surgery. ERAS (vs. non-ERAS) patients who had ACDF surgery had 1.64 lower average NRS (p=.006). ERAS (vs. non-ERAS) patients who had a different surgery had 0.72 higher average NRS (p=.02) but had almost half the length of stay, on average (p<.001).

CONCLUSIONS

The current study underscores the dynamic nature of ERAS protocols within the realm of spine surgery. While ERAS demonstrates advantages such as reduced LOS and improved patient-reported outcomes, it requires careful implementation and customization to address the specific demands of each surgical discipline. The potential to expedite recovery, optimize resource utilization, and enhance patient satisfaction cannot be overstated. However, the fine balance between achieving these benefits and ensuring comprehensive patient care, especially in the context of postoperative pain management, must be maintained. As ERAS continues to evolve and find its place in diverse surgical domains, it is crucial for healthcare providers to remain attentive to patient needs, adapting ERAS protocols to suit individual patient populations and surgical contexts.

Assessment of pre-, peri-, and post-surgical practices for elective colorectal patients in a model 4 hospital in Ireland

INTRODUCTION

The ERAS protocol is a set of international guidelines established to expedite patients' discharge after colorectal surgery. It does this by aiming to prevent postoperative complications early, and return the patient to normal function allowing earlier discharge. Complications such as PONV, DVT, ileus and pain are common after surgery to name a few, and delay discharge. Early treatment and prevention of these complications however is suggested to aid a patients' return to home at earlier rates than traditional practice.

METHODS

A prospective chart review and questionnaire was performed on patients undergoing colorectal surgery in UHL in a 6-month period from February to September 2023. Patients were approached on the 3rd day postoperatively and informed about the project. Exclusion criteria included patients who went to HDU or ICU postoperatively.

RESULTS

In total, 33 patients were recruited. A target of greater than 70% compliance was reached for a variety of the elements of the ERAS protocol such as laparoscopic surgery, preoperative assessments, nutritional drinks, LMWH, oral intake within 24 h of surgery, and intraoperative antiemetics. Unsatisfactory compliance was found with documentation of postoperative antibiotics use of preoperative gabapentin.

CONCLUSION

UHL has a satisfactory compliance of over 70% with a large variety of elements of the ERAS protocol. Areas of improvement required include postoperative antibiotic and preoperative gabapentin usage. With the collective effort of the multidisciplinary team, along with education, the ERAS protocol can successfully be applied and implemented in a model 4 hospital in Ireland.

Postoperative Multimodal Analgesia Strategy for Enhanced Recovery After Surgery in Elderly Colorectal Cancer Patients

Enhanced Recovery After Surgery (ERAS) protocols have substantially proven their merit in diminishing recuperation durations and mitigating postoperative adverse events in geriatric populations undergoing colorectal cancer procedures. Despite this, the pivotal aspect of postoperative pain control has not garnered the commensurate attention it deserves. Typically, employing a multimodal analgesia regimen that weaves together nonsteroidal anti-inflammatory drugs, opioids, local anesthetics, and nerve blocks stands paramount in curtailing surgical complications and facilitating reduced convalescence within hospital confines. Nevertheless, this integrative pain strategy is not devoid of pitfalls; the specter of organ dysfunction looms over the geriatric cohort, rooted in the abuse of analgesics or the complex interplay of polypharmacy. Revolutionary research is delving into alternative delivery and release modalities, seeking to allay the inadvertent consequences of analgesia and thereby potentially elevating postoperative outcomes for the elderly post-colorectal cancer surgery populace. This review examines the dual aspects of multimodal analgesia regimens by comparing their established benefits with potential limitations and offers insight into the evolving strategies of drug administration and release.

Enhanced Recovery Protocol Versus Conventional Care in Patients Undergoing Esophagectomy for Cancer: Advantages in Clinical and Patient-Reported Outcomes

BACKGROUND

This study was designed to compare the clinical and patient-reported outcomes (PROs) between the enhanced recovery after surgery (ERAS) protocol and conventional care in patients undergoing esophagectomy for cancer, which have not previously been compared.

METHODS

This single-center retrospective study included prospective PRO data from August 2019 to June 2021. Clinical outcomes included perioperative complications and postoperative length of stay (PLOS). Patient-reported outcomes were assessed by using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and esophagus-specific module (QLQ-OES18) preoperatively to 6 months postoperatively. Mixed-effects models were used to longitudinally compare quality of life (QOL) scores between the two modes.

RESULTS

Patients undergoing conventional care and ERAS were analyzed (n = 348 and 109, respectively). The ERAS group had fewer overall complications, pneumonia, arrhythmia, and a shorter PLOS than the conventional group, and outperformed the conventional group in five functional QLQ-C30 domains and five symptom QLQ-OES18 domains, including less dysphagia (p < 0.0001), trouble talking (p = 0.0006), and better eating (p < 0.0001). These advantages persisted for 3 months postoperatively. For the cervical circular stapled anastomosis, the initial domains and duration of benefit were reduced in the ERAS group.

CONCLUSIONS

The ERAS protocol has significant advantages over conventional care in terms of clinical outcomes, lowering postoperative symptom burden, and improving functional QOL in patients who have undergone esophagectomy. Selection of the optimal technique for cervical anastomosis is a key operative component of ERAS that maintains the symptom domains and duration of the advantages of PROs.

Sustained improved emergency laparotomy outcomes over 3 years after a transdisciplinary perioperative care pathway-A 1:1 propensity score matched study

BACKGROUND

Emergency laparotomy is associated with high morbidity and significant global health burden. This study aims to compare postoperative outcomes of patients who underwent emergency laparotomy before and after implementation of a emergency laparotomy pathway.

METHODS

This is a single-center study of all patients who presented with an acute abdomen and/or conditions requiring emergency laparotomy during pre-emergency laparotomy pathway (retrospective cohort from January 2016 to December 2018) and after the emergency laparotomy pathway (prospective cohort from January 2019 to December 2021). Patients who underwent emergency laparotomy for trauma or vascular surgery were excluded. A 1:1 propensity score matching was performed to address for confounding factors.

RESULTS

There were 888 patients (emergency laparotomy pathway, n = 428, and pre-emergency laparotomy pathway, n = 460) in the unmatched cohort. The mean age was 63.0 ± 15.4 years, and 43.8% had predicted mortality >10% using Portsmouth-Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity. The most common indication for emergency laparotomy was intestinal obstruction (30.5%). Overall incidence rates of major morbidity and 30-day mortality were 16.2% and 3.5%, respectively. There were 736 patients (n = 368 patients per arm) after propensity score matching. Demographic characteristics were comparable after propensity score matching. The emergency laparotomy pathway was associated with more patients assessed by geriatric medicine (odds ratio = 15.22; P < .001), reduced major morbidity (odds ratio = 0.63; P = .024), reduced intra-abdominal collection (odds ratio = 0.39; P = .006), and need for unplanned radiological and/or surgical intervention after index emergency laparotomy (odds ratio = 0.63; P = .024). Length of stay and 30-day mortality were comparable between the emergency laparotomy pathway and pre-emergency laparotomy pathway in both the unmatched and propensity score matched cohort.

CONCLUSION

Sustained improved postoperative outcomes were achieved 3 years postimplementation of the emergency laparotomy pathway .

Multimodal prehabilitation in elective oncological colorectal surgery enhances postoperative functional recovery: A secondary analysis of the PREHAB randomized clinical trial

INTRODUCTION

Colorectal cancer (CRC) ranks as the second leading cause of cancer-related deaths. The PREHAB trial revealed that prehabilitation in colorectal surgery leads to a reduction of severe complications and enhanced functional capacity. Nevertheless, risk selection for prehabilitation and the potential benefits for patients without postoperative complications remains unclear. This study aims to assess postoperative functional capacity, also in patients without postoperative complications.

MATERIALS & METHODS

This study was a secondary analysis of the PREHAB trial. Functional capacity tests, including cardiopulmonary exercise testing (CPET), steep ramp test (SRT), 6-min walking test (6MWT), stair climb test (SCT), 30" sit-to-stand test (STS), timed-up-and-go test (TUG), and muscle strength assessments, were conducted at baseline (T0) and 4 weeks postoperatively (T3). The primary outcome was the relative change in functional capacity from baseline to postoperative (ΔT0-T3) per group (i.e., prehabilitation vs control). Secondary, identical analysis were performed for patients without postoperative complications in each group.

RESULTS

Intention-to-treat analysis included 251 patients. For postoperative functional capacity, prehabilitation patients showed improvements in VO2peak (p = 0.024), VO2AT (p = 0.017), SRT (p = 0.001), 6MWT (p = 0.049), SCT (p = 0.012), and STS (p = 0.001) compared to the control group. Regarding muscle strength, prehabilitation patients showed improvements in estimated 1RM lateral pull down (p = 0.016), 1RM chest press (p = 0.001), 1RM leg press (p = 0.001) and HGS (p = 0.005) compared to controls. Additionally, prehabilitation patients more often reached baseline levels at T3 in VO2AT (p = 0.037), SRT (p = 0.008), 6MWT (p = 0.013), STS (p = 0.012), estimated 1RM lateral pull down (p = 0.002), 1RM chest press (p = 0.001) and 1RM leg press (p = 0.001) compared to controls. Moreover, even patients without postoperative complications in the prehabilitation group showed better postoperative functional capacity and more often reached baseline levels at T3, compared to controls.

CONCLUSION

Multimodal prehabilitation in CRC surgery is associated with improved postoperative functional capacity, even in patients without postoperative complications.

Quality of life following perioperative optimization with nutritional supplements in patients undergoing gastrointestinal surgery for cancer: A randomized, placebo-controlled feasibility clinical trial

BACKGROUND

Up to two thirds of patients presenting for abdominal cancer surgery are malnourished pre-operatively. Perioperative nutritional supplementation has been proposed to improve surgical outcomes, though its effect on quality of life (QoL) is not yet understood.

METHODS

A randomized controlled feasibility trial for perioperative nutrition among patients undergoing major abdominal cancer surgery was conducted. Participants in the intervention group received supplements for 30 days before surgery. Participants completed two QoL questionnaires (EORTC-QLQ-C-30 and FACT-G) at baseline, then 4 and 12 weeks postoperatively. Participants were compared between and within groups at baseline, Weeks 4, and 12 using t tests. Minimal clinically important differences (MCIDs) were considered as a 10-point worsening from baseline.

RESULTS

Sixty-six participants were available for analysis in this study, including 33 in the intervention and 30 in the control arms. Baseline demographics were balanced between groups except for different rates of pancreas cancer (36% intervention vs. 9% control) and colorectal cancer (19% intervention vs. 34% control). At baseline, participants in the intervention group had lower overall QoL (59% vs. 77%, p = 0.01), role functioning (72% vs 88%, p = 0.045), and cognitive functioning (79% vs 90%, p = 0.047). Following surgery, role and physical functioning worsened in the control group, without significant differences between groups. Role functioning was persistently worsened at 12 weeks in the control group. The rates of MCIDs were similar between both intervention and control groups.

DISCUSSION

Perioperative nutrition was associated with preservation of QoL in the postoperative period following major abdominal cancer surgery compared to placebo.

SUMMARY

Among patients undergoing surgery for cancer, the majority present at high risk for malnutrition. In this placebo-controlled randomized trial among patients undergoing major abdominal surgery for cancer, preoperative nutrition supplementation was associated with the preservation of QoL in the postoperative period.

Development and external validation of preoperative clinical prediction models for postoperative outcomes including preoperative aerobic fitness in patients approaching elective colorectal cancer surgery

INTRODUCTION

Preoperative aerobic fitness is associated with postoperative outcomes after elective colorectal cancer (CRC) surgery. This study aimed to develop and externally validate two clinical prediction models incorporating a practical test to assess preoperative aerobic fitness to distinguish between patients with and without an increased risk for 1) postoperative complications and 2) a prolonged time to in-hospital recovery of physical functioning after elective colorectal cancer (CRC) surgery.

MATERIALS AND METHODS

Models were developed using prospective data from 256 patients and externally validated using prospective data of 291 patients. Postoperative complications were classified according to Clavien-Dindo. The modified Iowa level of assistance scale (mILAS) was used to determine time to postoperative in-hospital physical recovery. Aerobic fitness, age, sex, body mass index, American Society of Anesthesiologists (ASA) classification, neoadjuvant treatment, surgical approach, tumour location, and preoperative haemoglobin level were potential predictors. Areas under the curve (AUC), calibration plots, and Hosmer-Lemeshow tests evaluated predictive performance.

RESULTS

Aerobic fitness, sex, age, ASA, tumour location, and surgical approach were included in the final models. External validation of the model for complications and postoperative recovery presented moderate to fair discrimination (AUC 0.666 (0.598-0.733) and 0.722 (0.651-0.794), respectively) and good calibration. High sensitivity and high negative predictive values were observed in the lower predicted risk categories (<40 %).

CONCLUSION

Both models identify patients with and without an increased risk of complications or a prolonged time to in-hospital physical recovery. They might be used for improving patient-tailored preoperative risk assessment and targeted and cost-effective application of prehabilitation interventions.

Predictors of postoperative opioid use in ventral and incisional hernia repair

BACKGROUND

One in two ventral and incisional hernia repair (VIHR) patients have preoperative opioid prescription within a year before procedure. The study's aim was to investigate risk factors of increased postoperative prescription filling in patients with or without preoperative opioid prescription.

METHODS

VIHR cases from 2013 to 2017 were reviewed. State prescription drug monitoring program data were linked to patient records. The primary endpoint was cumulative opioid dose dispensed through post-discharge day 45. Morphine milligram equivalent (MME) was used for uniform comparison.

RESULTS

205 patients were included in the study (average age 53.5 years; 50.7% female). Over 35% met criteria for preoperative opioid use. Preoperative opioid tolerance, superficial wound infection, current smoking status, and any dispensed opioids within 45 days of admission were independent predictors for increased postoperative opioid utilization (p < 0.001).

CONCLUSION

Preoperative opioid use during 45-day pre-admission correlated strongly with postoperative prescription filling in VIHR patients, and several independent risk factors were identified.

Effectiveness of erector spinae plane block in reducing opioid consumption after colorectal surgery: A comprehensive meta-analysis

Despite the life-saving nature of colorectal surgeries, patients often experience intra and post-operative problems, especially pain and discomfort. This meta-analysis aimed to evaluate the effectiveness of erector spinae plane block (ESP block) in postoperative pain management for patients undergoing colorectal surgeries. A comprehensive systematic literature search was conducted in PubMed and Cochrane Library databases from inception until December 2023. Eight studies were deemed appropriate for inclusion. The pooled analysis demonstrated a significant decrease with the ESP block compared to the control group in postoperative opioid consumption [MD ​= ​-15.96 ​mg; 95 ​% CI (-28.74 to -3.18); p ​= ​0.014, I2 ​= ​87 ​%], intraoperative opioid consumption [MD ​= ​-35.51 ​mg; 95 ​% CI (-62.63 to -8.40); p ​= ​0.010, I2 ​= ​87 ​%], pain scores [MD ​= ​-0.94; 95 ​% CI (-1.27 to -0.60); p ​< ​0.000001, I2 ​= ​86 ​%], with a significantly shorter duration of hospital stay [MD ​= ​-1.25 days; 95 ​% CI (-2.02 to -0.48); p ​= ​0.002, I2 ​= ​23 ​%]. This meta-analysis support the use of erector spinae plane block (ESP) for postoperative pain management in colorectal surgeries. ESP shows significant reductions in opioid consumption, pain scores and hospital stay.

Feasibility of the ERAS (Enhanced Recovery After Surgery) Protocol in Patients Undergoing Gastrointestinal Cancer Surgeries in a Tertiary Care Hospital-A Prospective Interventional Study

Enhanced Recovery After Surgery (ERAS) protocols have emerged as a promising approach to optimize perioperative care and improve outcomes in various surgical specialties. Despite feasibility studies on ERAS in various surgeries, there remains a paucity of research focusing on gastrointestinal cancer surgeries in the Indian context. The primary objective is to evaluate the compliance rate of the ERAS protocol and secondary objectives include the compliance rate of individual components of the protocol, the complications, the length of hospital stay, and the challenges faced during implementation in patients undergoing gastrointestinal cancer surgeries in our tertiary care cancer center. In this prospective interventional study (CTRI/2022/04/041657; registered on 05/04/2022), we evaluated 50 patients aged 18 to 70 years undergoing surgery for gastrointestinal malignancies and implemented a refined ERAS protocol tailored to our institutional resources and conditions based on standard ERAS society recommendations for gastrointestinal surgeries and specific recommendations for colorectal, pancreatic, and esophageal surgeries.Our study's mean overall compliance rate with the ERAS protocol was 88.54%. We achieved a compliance rate of 91.98%, 81.66%, and 92.00% for pre-operative, intraoperative, and post-operative components respectively. Fourteen (28%) patients experienced complications during the study. The median length of stay was 6.5 days (5.25-8). Challenges were encountered during the preoperative, intraoperative, and postoperative phases. The study highlighted the feasibility of implementing the ERAS protocol in a cancer institute, but specific challenges need to be addressed for its optimal success in gastrointestinal cancer surgeries.

Candidate Kidney Protective Strategies for Patients Undergoing Major Abdominal Surgery: A Secondary Analysis of the RELIEF Trial Cohort

BACKGROUND

Acute kidney injury (AKI) is common after major abdominal surgery. Selection of candidate kidney protective strategies for testing in large trials should be based on robust preliminary evidence.

METHODS

A secondary analysis of the Restrictive versus Liberal Fluid Therapy in Major Abdominal Surgery (RELIEF) trial was conducted in adult patients undergoing major abdominal surgery and randomly assigned to a restrictive or liberal perioperative fluid regimen. The primary outcome was maximum AKI stage before hospital discharge. Two multivariable ordinal regression models were developed to test the primary hypothesis that modifiable risk factors associated with increased maximum stage of postoperative AKI could be identified. Each model used a separate approach to variable selection to assess the sensitivity of the findings to modeling approach. For model 1, variable selection was informed by investigator opinion; for model 2, the Least Absolute Shrinkage and Selection Operator (LASSO) technique was used to develop a data-driven model from available variables.

RESULTS

Of 2,444 patients analyzed, stage 1, 2, and 3 AKI occurred in 223 (9.1%), 59 (2.4%), and 36 (1.5%) patients, respectively. In multivariable modeling by model 1, administration of a nonsteroidal anti-inflammatory drug or cyclooxygenase-2 inhibitor, intraoperatively only (odds ratio, 1.77 [99% CI, 1.11 to 2.82]), and preoperative day-of-surgery administration of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker compared to no regular use (odds ratio, 1.84 [99% CI, 1.15 to 2.94]) were associated with increased odds for greater maximum stage AKI. These results were unchanged in model 2, with the additional finding of an inverse association between nadir hemoglobin concentration on postoperative day 1 and greater maximum stage AKI.

CONCLUSIONS

Avoiding intraoperative nonsteroidal anti-inflammatory drugs or cyclooxygenase-2 inhibitors is a potential strategy to mitigate the risk for postoperative AKI. The findings strengthen the rationale for a clinical trial comprehensively testing the risk-benefit ratio of these drugs in the perioperative period.

EDITOR’S PERSPECTIVE

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.

[eHealth applications for promotion of physical activity after visceral surgery : A systematic review]

BACKGROUND

eHealth applications can support early mobilization and physical activity (PA) after surgery. This systematic review provides an overview of eHealth services to enhance or record PA after visceral surgery interventions.

METHODS

Two electronic databases (MEDLINE PubMed and Web of Science) were systematically searched (November 2023). Articles were considered eligible if they were controlled trials and described digital devices used to promote PA after visceral surgery. The Cochrane risk of bias (RoB-2) tool was used to determine the methodological quality of studies.

RESULTS

A total of nine randomized controlled studies (RCT) were included in this systematic review. The studies differed with respect to the interventions, surgical indications and evaluation variables. The risk of bias of the individual studies was moderate. The six studies using activity trackers (AT) predominantly showed insignificant improvements in the postoperative step count. The more complex fitness applications could partially reveal significant advantages compared to the control groups and the home-based online training also showed a significant increase in functional capacity.

CONCLUSION

Activity tracking alone has so far failed to show clinically relevant effects. In contrast, the more complex eHealth applications revealed advantages compared to usual postoperative care. More high-quality studies are needed for evidence-based recommendations for eHealth services in conjunction with visceral surgery.

The effects of oral nutritional supplements interventions on nutritional status in patients undergoing colorectal cancer surgery: A systematic review

BACKGROUND

The high incidence of malnutrition in patients undergoing colorectal cancer surgery can lead to unplanned weight loss, sarcopenia and reduced grip strength to the extent that it can seriously affect the prognosis of colorectal cancer patients.

OBJECTIVE

This study investigated the effect of oral nutritional supplements (ONS) on the prevalence of grip strength, unplanned weight loss and sarcopenia in patients undergoing colorectal cancer surgery.

METHODS

We systematically searched randomized controlled studies from CINAHL, PubMed, Embase, Cochrane and Web of Science and three Chinese databases (CNKI, Wan-Fang database, VIP database) from database creation to September 2023. The risk of bias in individual studies was assessed using the Cochrane Collaboration tool, and the certainty of evidence was assessed using the five GRADE criteria. Statistical analysis was performed using the RevMan 5.3 software, and information that could not be meta-analysed was reviewed in the form of a literature summary.

RESULTS

Eleven papers met the inclusion criteria with a combined sample size of 1070 cases, including 532 cases in the trial group and 538 cases in the control group. Four papers reported the effect of ONS on grip strength and included very low-quality evidence supporting no effect of ONS on grip strength. Ten studies reported the effect of ONS on body weight and body mass index (BMI) and included very low-quality evidence supporting a positive ONS on weight and BMI changes. Meta-analysis showed a significant reduction in weight loss (12-15 weeks) and BMI loss (12-15 weeks) in patients with colorectal cancer in the ONS group. The effect of ONS on the prevalence of sarcopenia after hospital discharge was reported in two studies, and meta-analysis showed a significant reduction in the prevalence of postoperative sarcopenia in colorectal cancer patients in the ONS group, but the quality of evidence was low.

CONCLUSIONS

This study showed that the use of ONS in patients undergoing surgery for colorectal cancer improved patient weight loss and BMI reduction and reduced the prevalence of postoperative sarcopenia but did not improve patient grip strength. The quality of evidence for inclusion in the article was low or very low, and further studies are needed to provide better evidence.

Bowel endometriosis: Surgical customization is demanding

Bowel endometriosis is the most common form of severe deep endometriosis. Surgery is an option in case of infertility and/or chronic pain or in the presence of a stenotic lesion. Clinical examination and preoperative imaging must provide an identity card of the lesion so that customized surgery can be proposed. The primary objective of this tailor-made surgery will always be to preserve the organ. The surgeon then has three options: shaving, discoid resection and segmental resection. The more extensive the resection, the greater the risk of severe short- and long-term complications. Surgery must therefore be adapted to the patient's specific situation and needs. Moreover, personalized care must extend beyond surgery. It must begin before the operation, preparing the patient for the operation like an athlete before a race, and continue afterwards by adapting the follow-up to the surgery performed.

Motivational Interviewing improves postoperative nutrition goals within the Enhanced Recovery after Surgery (ERAS®) pathway in elective bowel surgery - A randomized clinical pilot trial

BACKGROUND & AIMS

Exploration whether Motivational Interviewing (MI) could be learned and implemented with ease within a surgical in-hospital setting and whether participation in the intervention led to significantly higher compliance with ERAS®-recommended protein intake goals. The individual healing process of many patients is delayed because they fail to cover their calorie requirement, which could be counteracted by a patient-centered conversational intervention that is new in perioperative practice.

METHODS

This patient-blinded pilot-RCT included 60 patients (≥18 years) following the certified ERAS® bowel protocol for colorectal surgery between March and August 2022. Five perioperative MI interventions were conducted by two health employees certified to perform MI. Key endpoints were the number of protein shakes drunk, calories of proteins ingested and overall calorie intake.

RESULTS

A total of 60 patients (34 men [56.7%]; mean [SD] age, 60.7 [13.3] years) were randomized. MI patient-group had significantly higher protein shake intake on all postoperative days except day 3. For days 0-3 MI group drank significantly more shakes overall (median 5.5 vs. 2.0; P = 0.004) and consumed more calories (median 1650.0 vs. 600.0 kcal; P = 0.004) and proteins (median 110.0 vs. 40.0 g; P = 0.005). Total calorie intake for each day by shakes and dietary intake was significantly higher in the MI-intervention group on day 2 (mean 1772.3 vs. 1358.9 kcal; P = 0.03).

CONCLUSIONS

MI may contribute to improve compliance with nutritional goals in the certified ERAS® protocol by increasing protein and calorie intake. The findings suggest further investigation of MI to help patients achieve their perioperative nutrition goals in different clinical settings.

Differences in the Receipt of Regional Anesthesia Based on Race and Ethnicity in Colorectal Surgery

BACKGROUND

Health equity in pain management during the perioperative period continues to be a topic of interest. The authors evaluated the association of race and ethnicity with regional anesthesia in patients who underwent colorectal surgery and characterized trends in regional anesthesia.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program database from 2015 to 2020, the research team identified patients who underwent open or laparoscopic colorectal surgery. Associations between race and ethnicity and use of regional anesthesia were estimated using logistic regression models.

RESULTS

The final sample size was 292,797, of which 15.6% (n = 45,784) received regional anesthesia. The unadjusted rates of regional anesthesia for race and ethnicity were 15.7% white, 15.1% Black, 12.8% Asian, 29.6% American Indian or Alaska Native, 16.3% Native Hawaiian or Pacific Islander, and 12.4% Hispanic. Black (odds ratio [OR] 0.93, 95% confidence interval [CI] 0.90-0.96, p < 0.001) and Asian (OR 0.76, 95% CI 0.71-0.80, p < 0.001) patients had lower odds of regional anesthesia compared to white patients. Hispanic patients had lower odds of regional anesthesia compared to non-Hispanic patients (OR 0.72, 95% CI 0.68-0.75, p < 0.001). There was a significant annual increase in regional anesthesia from 2015 to 2020 for all racial and ethnic cohorts (p < 0.05).

CONCLUSION

There was an annual increase in the use of regional anesthesia, yet Black and Asian patients (compared to whites) and Hispanics (compared to non-Hispanics) were less likely to receive regional anesthesia for colorectal surgery. These differences suggest that there are racial and ethnic differences in regional anesthesia use for colorectal surgery.

Evaluation of Laparoscopic Colorectal Resection Among Elderly Individuals With Colorectal Malignancy: A Single-center Retrospective Analysis

OBJECTIVE

The purpose of the current study was to statistically clarify the precise risk age in elderly patients undergoing colorectal surgery and to evaluate the safety and efficacy of laparoscopic colorectal resection in these patients.

METHODS

Patients' clinical variables were extracted from the database of the Gastrointestinal Surgery Centre, Third Affiliated Hospital of Sun Yat-sen University, from 2015 to 2019. Logistic regression was conducted to identify independent risk factors of postoperative complications and ORs for each age. Curves of odds ratios (ORs) and CIs for each age were fitted by using a locally weighted scatterplot smoother, and a structural breakpoint was determined by the Chow test to identify a precise cutoff risk age for elderly patients. Comparison and subgroup analysis were conducted between surgical approach groups using the Student t test and χ 2 analysis.

RESULTS

Locally weighted scatterplot smoother OR analysis manifested that patients aged 69 years old or older suffered a higher possibility of postoperative complications and should be defined as high-risk age. Comparison according to the high-risk age revealed laparoscopic colorectal surgery is better than laparotomic surgery for elderly individuals in terms of hospital stay (9.46 ± 5.96 vs 15.01 ± 6.34, P < 0.05), the incidence of intensive care unit transfer (4 vs 20, P < 0.05), and incidence of surgical site infection (15 vs 20, P < 0.05). Patients who underwent laparotomic surgery had a greater prevalence of Clavien-Dindo II/III complications ( P < 0.05). These findings remained stable even after propensity matching. Furthermore, such superiority was proved especially significant for patients who underwent left-side colorectal resection. In addition, overall survival was improved in the laparoscopic surgery group, whereas no differences were observed in disease-free survival.

CONCLUSION

In our study population, age 69 or older was a cutoff point age suggests a higher possibility of postoperative morbidity after colorectal surgery. Laparoscopic colorectal resection should be regarded as a superior therapeutic choice for these elderly individuals, especially for left-side colorectal surgeries.

So many measures in ERAS protocol: Which matters most?

OBJECTIVES

Enhanced recovery after surgery (ERAS), which includes multiple measures, has gradually become the standard perioperative management in pediatric surgery. However, it is still unclear which of its many measures affects the outcomes more.

METHODS

We retrospectively analyzed the medical records of children with congenital choledochal cysts who underwent surgical treatment in a specialized children's hospital from January 2019 to December 2022. Data including baseline factors, implementation of ERAS interventions, postoperative complications, and postoperative length of stay (PLOS) were collected. Univariate and multivariate analyses were performed to identify the association between PLOS and baseline factors or specific ERAS measures.

RESULTS

The implementation rate of ERAS measures ranged from 5.02% to 100% in 219 cases who underwent 3 to 14 ERAS measures. Univariate analysis showed that body mass index-for-age z-scores, liver function indicators, and postoperative complications were the significant baseline factors for PLOS. At the same time, the measures with the greatest effect on PLOS were early postoperative feeding and early removal of tubes. Multivariate analysis with different models revealed that postoperative complications, early postoperative feeding, and early catheter removal influenced the PLOS the most.

CONCLUSIONS

A prolonged PLOS was associated with poor preoperative nutritional status, elevated liver function indexes, and postoperative complications. Early postoperative feeding and removal of tubes appeared more likely with a reduced PLOS than other measures, requiring more attention when implementing the ERAS protocol.

Prehabilitation of surgical patients: a bibliometric analysis from 2005 to 2023

BACKGROUND

Good preoperative conditions help patients to counteract surgical injury. Prehabilitation is a multimodal preoperative management strategy, including physical, nutritional, psychological, and other interventions, which can improve the functional reserve of patients and enhance postoperative recovery. The purpose of this study is to show the evolution trend and future directions of research related to the prehabilitation of surgical patients.

METHODS

The global literature regarding prehabilitation was identified from The Web of Science Core Collection database. Bibliometric methods of the Bibliometrix package of R (version 4.2.1) and VOSviewer were used to analyze publication trends, cooperative networks, study themes, and co-citation relationships in the field.

RESULTS

A total of 638 publications were included and the number of publications increased rapidly since 2016, with an average annual growth rate of 41.0%. "Annals of Surgery", "British Journal of Surgery" and "British Journal of Anesthesia" were the most cited journals. Experts from the USA, Canada, the UK, and the Netherlands contributed the most in this field, and an initial cooperative network among different countries and clinical teams was formed. Malnutrition, older patients, frailty, and high-risk patients were the hotspots of recent studies. However, among the top 10 cited articles, the clinical effects of prehabilitation were conflicting.

CONCLUSION

This bibliometric review summarized the most influential publications as well as the publication trends and clarified the progress and future directions of prehabilitation, which could serve as a guide for developing evidence-based practices.

Impact of spinal or epidural anaesthesia on perioperative outcomes in adult noncardiac surgery: a narrative review of recent evidence

Spinal and epidural anaesthesia and analgesia are important anaesthetic techniques, familiar to all anaesthetists and applied to patients undergoing a range of surgical procedures. Although the immediate effects of a well-conducted neuraxial technique on nociceptive and sympathetic pathways are readily observable in clinical practice, the impact of such techniques on patient-centred perioperative outcomes remains an area of uncertainty and active research. The aim of this review is to present a narrative synthesis of contemporary clinical science on this topic from the most recent 5-year period and summarise the foundational scholarship upon which this research was based. We searched electronic databases for primary research, secondary research, opinion pieces, and guidelines reporting the relationship between neuraxial procedures and standardised perioperative outcomes over the period 2018-2023. Returned citation lists were examined seeking additional studies to contextualise our narrative synthesis of results. Articles were retrieved encompassing the following outcome domains: patient comfort, renal, sepsis and infection, postoperative cancer, cardiovascular, and pulmonary and mortality outcomes. Convincing evidence of the beneficial effect of epidural analgesia on patient comfort after major open thoracoabdominal surgery outcomes was identified. Recent evidence of benefit in the prevention of pulmonary complications and mortality was identified. Despite mechanistic plausibility and supportive observational evidence, there is less certain experimental evidence to support a role for neuraxial techniques impacting on other outcome domains. Evidence of positive impact of neuraxial techniques is best established for the domains of patient comfort, pulmonary complications, and mortality, particularly in the setting of major open thoracoabdominal surgery. Recent evidence does not strongly support a significant impact of neuraxial techniques on cancer, renal, infection, or cardiovascular outcomes after noncardiac surgery in most patient groups.

The implementation of an inflammatory bowel disease-specific enhanced recovery after surgery protocol: an observational cohort study

BACKGROUND

The implementation of Enhanced Recovery After Surgery (ERAS) protocols has resulted in improved postoperative outcomes in colorectal cancer surgery. The evidence regarding feasibility and impact on outcomes in surgery for inflammatory bowel disease (IBD) is limited.

METHODS

We performed a retrospective observational cohort study, comparing patient trajectories before and after implementing an IBD-specific ERAS protocol at Zealand University Hospital. We assessed the occurrence of serious postoperative complications of Clavien-Dindo grade 3 or higher as our primary outcome, with postoperative length of stay in days and rate of readmissions as secondary outcomes, using χ2, Mann-Whitney test, and odds ratios adjusted for sex and age.

RESULTS

From 2017 to 2023, 394 patients were operated on for IBD and included in our study. In the ERAS cohort, 39/250 patients experienced a postoperative complication of Clavien-Dindo grade 3 or higher compared to 27/144 patients in the non-ERAS cohort (15.6% vs. 18.8%, p = 0.420) with an adjusted odds ratio of 0.73 (95% CI 0.42-1.28). There was a significantly shorter postoperative length of stay (median 4 vs. 6 days, p < 0.001) in the ERAS cohort compared to the non-ERAS cohort. Readmission rates remained similar (22.4% vs. 16.0%, p = 0.125).

CONCLUSIONS

ERAS in IBD surgery was associated with faster patient recovery, but without an impact on the occurrence of serious postoperative complications and rate of readmissions.

Clinicians' perceptions of "enhanced recovery after surgery" (ERAS) protocols to improve patient safety in surgery: a national survey from Australia

BACKGROUND

Surgical patients are at risk of postoperative complications, which may lead to increased morbidity, mortality, hospital length-of-stay and healthcare costs. Enhanced Recovery After Surgery (ERAS®) protocols are evidence-based and have demonstrated effectiveness in decreasing complications and associated consequences. However, their adoption in Australia has been limited and the reason for this is unclear. This study aimed to describe clinicians' perceptions of ERAS protocols in Australia.

METHODS

A national online survey of anaesthetists, surgeons and nurses was undertaken. Invitations to participate were distributed via emails from professional colleges. The 30-item survey captured respondent characteristics, ERAS perceptions, beliefs, education and learning preferences and future planning considerations. The final question was open-ended for elaboration of perceptions of ERAS. Descriptive and inferential statistics were used to describe and compare group differences across disciplines relative to perceptions of ERAS.

RESULTS

The sample included 178 responses (116 nurses, 65.2%; 36 surgeons, 20.2%; 26 anaesthetists, 14.6%) across six states and two territories. More than half (n = 104; 58.8%) had used ERAS protocols in patient care, and most perceived they were 'very knowledgeable' (n = 24; 13.6%) or 'knowledgeable' (n = 71; 40.3%) of ERAS. However, fewer nurses had cared for a patient using ERAS (p <.01) and nurses reported lower levels of knowledge (p <.001) than their medical counterparts. Most respondents agreed ERAS protocols improved patient care and financial efficiency and were a reasonable time investment (overall Md 3-5), but nurses generally recorded lower levels of agreement (p.013 to < 0.001). Lack of information was the greatest barrier to ERAS knowledge (n = 97; 62.6%), while seminars/lectures from international and national leaders were the preferred learning method (n = 59; 41.3%). Most supported broad implementation of ERAS (n = 130; 87.8%).

CONCLUSION

There is a need to promote ERAS and provide education, which may be nuanced based on the results, to improve implementation in Australia. Nurses particularly need to be engaged in ERAS protocols given their significant presence throughout the surgical journey. There is also a need to co-design implementation strategies with stakeholders that target identified facilitators and barriers, including lack of support from senior administration, managers and clinicians and resource constraints.

Early Single-Center Experience of DaVinci® Single-Port (SP) Robotic Surgery in Colorectal Patients

Background: DaVinci® single-port (SP) robotic surgery offers several benefits compared to traditional multiport laparoscopic or robotic surgeries. One of the main advantages is that it allows for a minimally invasive approach, resulting in a single, smaller incision and reduced trauma to the patient's body, leading to less postoperative pain, faster recovery, and reduced risk of complications. The cosmesis of a single port with minimal visible scarring is also an attractive aspect to the patients; however, many surgeons use an additional port for energy device, stapler use, and drain insertion. Pure single-port surgery with one incision is still rare. Here, we share our experience of our first 10 cases using the SP robotic platform in colorectal surgery. Methods: From May 2023 to December 2023, colorectal patients who underwent SP robotic surgery were analyzed. Placement of the incision was the umbilicus for eight patients, and right lower quadrant for two patients, through which ileostomy maturation was performed. Data on perioperative parameters and postoperative outcomes were analyzed, with a median follow-up of 4.6 months (range 0.6-7.4 months). Results: A total of 10 colorectal patients underwent DaVinci® single-port robotic colorectal surgery at our institution during this period. The patient demographic was four males (40%) and six females (60%) with a median age of 63.5 years (range 50-75 years). Median body mass index (BMI) was 22.89 kg/m2 (range 19.92-26.84 kg/m2). Nine patients were diagnosed with colorectal cancer, and one patient was diagnosed with a rectal gastrointestinal tumor. One patient underwent anterior resection and cholecystectomy simultaneously. Mean operation time was 222 min (range 142-316 min), and mean wound size was 3.25 cm (range 2.5-4.5 cm). Nine patients underwent surgery with single incision through which a single-port trocar was inserted, and one patient had one additional port for drain insertion. Mean hospital stay was 6 days (range 4-8 days) with one postoperative complication of bleeding requiring transfusion, but there was no readmission within 30 days. Conclusions: Overall, our experience with single-port robotic colorectal surgery has been promising. With only one patient with additional port for drain insertion, all nine patients underwent SP-robotic surgery with single incision for colon as well as rectal surgeries. Compared to an average postoperative length of stay of 6.5-8 days in laparoscopic colorectal surgeries reported in literature, SP-robotic surgery 33showed faster recovery of 6 days highlighting its benefits in patient recovery and satisfaction.

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.

The Enhanced Recovery after Surgery Approach in Heart Valve Surgery: A Systematic Review of Clinical Studies

Background: Enhanced recovery after surgery (ERAS) protocols aim to reduce postoperative complications and promote earlier recovery. Although it is well established in noncardiac surgery fields, the ERAS approach has only recently been adopted in cardiac surgery. The aim of this review is to evaluate the status and implementation of ERAS protocols in patients undergoing heart valve surgery and to summarise associated clinical results. Methods: A literature search for the period January 2015 and January 2024 was performed through online databases. Clinical studies (randomised controlled trials and cohort studies) on patients undergoing heart valve surgical procedures and comparing ERAS and conventional approaches were included. The data extracted covered studies and populations characteristics, early outcomes and the features of each ERAS protocol. Results: There were 14 studies that fulfilled the final search criteria and were ultimately included in the review. Overall, 5142 patients were identified in the 14 studies, with 2501 in ERAS groups and 2641 patients who were representative of control groups. Seven experiences exclusively included patients who underwent heart valve surgery. Twelve out of fourteen protocols involved multiple interventions from the preoperative to postoperative phase, while two studies reported actions limited to intraoperative and postoperative care. We found high heterogeneity among the included protocols regarding key actions targeted for improvement and measured outcomes. All the studies showed that ERAS pathways can be safely adopted in cardiac surgery and in most of the experiences were associated with shorter mechanical ventilation time, reduced postoperative opioid use and reduced ICU and hospital stays. Conclusions: As demonstrated in noncardiac surgery, the adoption of structured ERAS protocols has the potential to improve results in patients undergoing heart valve surgery. Further evidence based on larger populations is needed, including more homogenous pathways and reporting further outcomes in terms of patient satisfaction, recovery and quality of life after surgery.

Hyperbaric bupivacaine versus prilocaine for spinal anesthesia combined with total intravenous anesthesia during oncological colon surgery in a 23-hour stay enhanced recovery protocol: A non-randomized study

After the success of the enhanced recovery after surgery protocol, perioperative care has been further optimized in accelerated enhanced recovery pathways (ERPs), where optimal pain management is crucial. Spinal anesthesia was introduced as adjunct to general anesthesia to reduce postoperative pain and facilitate mobility. This study aimed to determine which spinal anesthetic agent provides best pain relief in accelerated ERP for colon carcinoma. This single center study was a secondary analysis conducted among patients included in the aCcelerated 23-Hour erAS care for colon surgEry study who underwent elective laparoscopic colon surgery. The first 30 patients included received total intravenous anesthesia combined with spinal anesthesia with prilocaine, the 30 patients subsequently included received spinal anesthesia with hyperbaric bupivacaine. Primary endpoint of this study was the total amount of morphine milligram equivalents (MMEs) administered during hospital stay. Secondary outcomes were amounts of MMEs administered in the recovery room and surgical ward, pain score using the numeric rating scale, complication rates and length of hospital stay. Compared to prilocaine, the total amount of MMEs administered was significantly lower in the bupivacaine group (n = 60, 16.3 vs 6.3, P = .049). Also, the amount of MMEs administered and median pain scores were significantly lower after intrathecal bupivacaine in the recovery room (MMEs 11.0 vs 0.0, P = .012 and numeric rating scale 2.0 vs 1.5, P = .004). On the surgical ward, median MMEs administered, and pain scores were comparable. Postoperative outcomes were similar in both groups. Spinal anesthesia with hyperbaric bupivacaine was associated with less opioid use and better pain reduction immediately after surgery compared to prilocaine within an accelerated ERP for elective, oncological colon surgery.

Divergent Trends in Postoperative Length of Stay and Postdischarge Complications over Time

BACKGROUND

There is a push toward shorter length of stay (LOS) after surgery by hospitals, payers, and policymakers. However, the extent to which these changes have shifted the occurrence of complications to the postdischarge setting is unknown. The objectives of this study were to (1) evaluate changes in LOS and postdischarge complications over time and (2) assess factors associated with postdischarge complications.

STUDY DESIGN

Patients who underwent surgery across five specialties (colorectal, esophageal, hepatopancreatobiliary [HPB], gynecology, and urology) were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) procedure-targeted database (2014-2019). Trends in the proportion of postdischarge complications within 30 days of surgery and predictors of postdischarge complications were assessed using multivariable logistic regression.

RESULTS

Among 538,172 patients evaluated, median LOS decreased from 3 (2014) to 2 days (2019) (p < 0.001). Overall, 12.2% of patients experienced a 30-day complication, with 50.4% occurring postdischarge. with the highest in hysterectomy (80.9%), prostatectomy (74.6%), and cystectomy (54.6%). The overall postoperative complication decreased, but the proportion of postdischarge complications increased from 44.6% (2014) to 56.4% (2019) (p < 0.001), including surgical site infection (superficial/deep/organ space/wound dehiscence), other infection (pneumonia/urinary tract infection/sepsis), cardiovascular (myocardial infarction/cardiac arrest/stroke), and venous thromboembolism. Factors associated with an increased odds of postdischarge complications included Hispanic or other race, higher American Society of Anesthesiologists class, dependent functional status, increased body mass index, higher wound class, inpatient complication, longer operation, and procedure type (HPB/colorectal/hysterectomy/esophagectomy, vs. prostatectomy) (all p < 0.001).

CONCLUSION

This comprehensive retrospective analysis across five representative surgical specialties highlighted that although LOS has decreased over time, the proportion of postdischarge complications has increased over time. Focusing on the development of a comprehensive, proactive, postdischarge monitoring system to better identify and manage postdischarge complications is necessary.

Robotic ambulatory colorectal resections: a systematic review

Colorectal surgery has progressed greatly via minimally invasive techniques, laparoscopic and robotic. With the advent of ERAS protocols, patient recovery times have greatly shortened, allowing for same day discharges (SDD). Although SDD have been explored through laparoscopic colectomy reviews, no reviews surrounding robotic ambulatory colorectal resections (RACrR) exist to date. A systematic search was carried out across three databases and internet searches. Data were selected and extracted by two independent reviewers. Inclusion criteria included robotic colorectal resections with a length of hospital stay of less than one day or 24 h. 4 studies comprising 136 patients were retrieved. 56% of patients were female and were aged between 21 and 89 years. Main surgery indications were colorectal cancer and recurrent sigmoid diverticulitis (43% each). Most patients had low anterior resections (48%). Overall, there was a 4% complication rate postoperatively, with only 1 patient requiring readmission due to postoperative urinary retention (< 1%). Patient selection criteria involved ASA score cut-offs, nutritional status, and specific health conditions. Protocols employed shared similarities including ERAS education, transabdominal plane blocks, early removal of urinary catheters, an opioid-sparing regime, and encouraged early oral intake and ambulation prior to discharge. All 4 studies had various follow-up methods involving telemedicine, face-to-face consultations, and virtual ward teams. RACrRs is safe and feasible in a highly specific patient population; however, further high-quality studies with larger sample sizes are needed to draw more significant conclusions. Several limitations included small sample size and the potential of recall bias due to retrospective nature of 2 studies.

PERIOPERATIVE CARE IN DIGESTIVE SURGERY: THE ERAS AND ACERTO PROTOCOLS - BRAZILIAN COLLEGE OF DIGESTIVE SURGERY POSITION PAPER

BACKGROUND

The concept introduced by protocols of enhanced recovery after surgery modifies perioperative traditional care in digestive surgery. The integration of these modern recommendations components during the perioperative period is of great importance to ensure fewer postoperative complications, reduced length of hospital stay, and decreased surgical costs.

AIMS

To emphasize the most important points of a multimodal perioperative care protocol.

METHODS

Careful analysis of each recommendation of both ERAS and ACERTO protocols, justifying their inclusion in the multimodal care recommended for digestive surgery patients.

RESULTS

Enhanced recovery programs (ERPs) such as ERAS and ACERTO protocols are a cornerstone in modern perioperative care. Nutritional therapy is fundamental in digestive surgery, and thus, both preoperative and postoperative nutrition care are key to ensuring fewer postoperative complications and reducing the length of hospital stay. The concept of prehabilitation is another key element in ERPs. The handling of crystalloid fluids in a perfect balance is vital. Fluid overload can delay the recovery of patients and increase postoperative complications. Abbreviation of preoperative fasting for two hours before anesthesia is now accepted by various guidelines of both surgical and anesthesiology societies. Combined with early postoperative refeeding, these prescriptions are not only safe but can also enhance the recovery of patients undergoing digestive procedures.

CONCLUSIONS

This position paper from the Brazilian College of Digestive Surgery strongly emphasizes that the implementation of ERPs in digestive surgery represents a paradigm shift in perioperative care, transcending traditional practices and embracing an intelligent approach to patient well-being.

Risk prediction algorithms for prolonged postoperative ileus: A systematic review

AIM

Prolonged postoperative ileus (PPOI) is common and is associated with a significant healthcare burden. Previous studies have attempted to predict PPOI clinically using risk prediction algorithms. The aim of this work was to systematically review and compare risk prediction algorithms for PPOI following colorectal surgery.

METHOD

A systematic literature search was conducted using MEDLINE, Embase, Web of Science and CINAHL Plus. Studies that developed and/or validated a risk prediction algorithm for PPOI in adults following colorectal surgery were included. Data were collected on study design, population and operative characteristics, the definition of PPOI used and risk prediction algorithm design and performance. Quality appraisal was assessed using the PROBAST tool.

RESULTS

Eleven studies with 87 549 participants were included in our review. Most were retrospective, single-centre analyses (6/11, 55%) and rates of PPOI varied from 10% to 28%. The most commonly used variables were sex (8/11, 73%), age (6/11, 55%) and surgical approach (5/11, 45%). Area under the curve ranged from 0.68-0.78, and only three models were validated. However, there was significant variation in the definition of PPOI used. No study reported sensitivity, specificity or positive/negative predictive values.

CONCLUSION

Currently available risk prediction algorithms for PPOI appear to discriminate moderately well, although there is a lack of validation data. Future studies should aim to use a standardized definition of PPOI, comprehensively report model performance and validate their findings using internal and external methodologies.

Pathophysiology and Management of Postoperative Ileus in Adults and Neonates: A Review

Postoperative ileus (POI) is caused by enteric neural dysfunction and inflammatory response to the stress of surgery as well as the effect of anesthetics and opioid pain medications. POI results in prolonged hospital stays, increased medical costs, and diminished enteral nutrition, rendering it a problem worth tackling. Many cellular pathways are implicated in this disease process, creating numerous opportunities for targeted management strategies. There is a gap in the literature in studies exploring neonatal POI pathophysiology and treatment options. It is well known that neonatal immune and enteric nervous systems are immature, and this results in gut physiology which is distinct from adults. Neonates undergoing abdominal surgery face similar surgical stressors and exposure to medications that cause POI in adults. In this review, we aim to summarize the existing adult and neonatal literature on POI pathophysiology and management and explore applications in the neonatal population.

Enhanced Recovery After Surgery protocols mitigate the weekend effect on length of stay following elective colectomy

BACKGROUND

This study aimed to determine the effect of Enhanced Recovery After Surgery (ERAS) protocols on the weekend effect after elective colectomies.

METHODS

This was a retrospective study on all elective colorectal surgeries at a single institution in New York City between January 1, 2015, and December 31, 2020. The length of stay (LOS) by day of the week of surgery and the effect of ERAS using univariable and multivariable analyses were compared.

RESULTS

A total of 605 patients were included in the study. Of note, 41 cases were performed on Mondays, 197 cases were performed on Tuesdays, 45 cases were performed on Wednesdays, 187 cases were performed on Thursdays, and 135 cases were performed on Fridays. Univariate analysis showed that, for patients who did not undergo ERAS, Monday and Tuesday were significantly associated with decreased LOS (P < .001). For patients who underwent ERAS, there was no statistically significant difference in LOS (P = .06) when operated on early in the week vs later. After controlling for age, race/ethnicity, comorbidities, complications, functional health status, operation type, duration of surgery, presence of ostomy, and albumin level, adhering to the ERAS protocol was significantly associated with a shorter LOS (P < .001).

CONCLUSION

Our study demonstrated that ERAS can mitigate the weekend effect on LOS. ERAS protocols may provide more structure to the expected hospital course and allow patients to reach recovery milestones earlier, facilitating discharge even by covering teams.

Early Versus Late Drainage Removal in Patients Who Underwent Pancreaticoduodenectomy: A Comprehensive Systematic Review and Meta-analysis of Randomized Controlled Trials Using Trial Sequential Analysis

BACKGROUND

The superiority of early drain removal (EDR) versus late (LDR) after pancreaticoduodenectomy (PD) has been demonstrated only in RCTs.

METHODS

A meta-analysis was conducted using a random-effects model and trial sequential analysis. The critical endpoints were morbidity, redrainage, relaparotomy, and postoperative pancreatic fistula (CR-POPF). Hemorrhage (PPH), delayed gastric emptying (DGE), length of stay (LOS), and readmission rates were also evaluated. Risk ratios (RRs) and mean differences (MDs) with a 95% confidence interval (CI) were calculated. Type I and type II errors were excluded, comparing the accrued sample size (ASS) with the required sample size (RIS). When RIS is superior to ASS, type I or II errors can be hypothesized.

RESULTS

ASS was 632 for all endpoints except DGE and PPH (557 patients). The major morbidity (RR 0.55; 95% CI 0.32-0.97) was lower in the EDR group. The CR-POPF rate was lower in the EDR than in the LDR group (RR 0.50), but this difference is not statistically significant (95% CI 0.24-1.03). The RIS to confirm or exclude these results can be reached by randomizing 5959 patients. The need for percutaneous drainage, relaparotomy, PPH, DGE, and readmission rates was similar. The related RISs were higher than ASS, and type II errors cannot be excluded. LOS was shorter in the EDR than the LDR group (MD - 2.25; 95% CI - 3.23 to - 1.28). The RIS was 567, and type I errors can be excluded.

CONCLUSIONS

EDR, compared with LDR, is associated with lower major morbidity and shorter LOS.

Time to Start a New Enhanced Recovery After Surgery (ERAS): A Retrospective Cohort Study

BACKGROUND

The enhanced recovery after surgery (ERAS®) is a multimodal perioperative care pathway designed to reduce surgical stress and ultimately improve patient recovery and outcome. It can require significant resources but with proven benefits. The main goal of this study was to perform a diagnostic assessment of perioperative practice in a local colorectal surgical center.

METHODS

93 patients who underwent elective colorectal surgery from January to December 2022 were analyzed. Preadmission, preoperative, and postoperative data of all patients were collected in a database developed by the researchers, according to ERAS® guidelines. Descriptive statistics were employed to summarize demographic and clinical characteristics. Chi-square and T-test were performed to identify possible associations between categorical variables and postoperative complications.

RESULTS

Overall analysis showed deficient preoperative patient optimization, especially regarding nutritional counseling and supplementation, smoking and alcohol cessation, anemia treatment (9%), and pre-anesthetic medication (42%). Removal of invasive devices was significantly delayed (removal of urinary catheter average on the fourthday and surgical drain average on the fifth day) in the postoperatively period and oral intake (average onset on the sixth day). Both contribute to hospital length of stay (mean of 13 days) and a significant number of complications.

CONCLUSION

The results lead us to an individual and multidisciplinary reflection on current practices and outcomes. ERAS® program, already adopted by many centers, could have a positive impact on the immediate postoperative recovery of colorectal patients in Funchal Central Hospital and implementation seems necessary.

A survey of preoperative surgical nutrition practices, opinions, and barriers across Canada

Malnutrition is prevalent among surgical candidates and associated with adverse outcomes. Despite being potentially modifiable, malnutrition risk screening is not a standard preoperative practice. We conducted a cross-sectional survey to understand healthcare professionals' (HCPs) opinions and barriers regarding screening and treatment of malnutrition. HCPs working with adult surgical patients in Canada were invited to complete an online survey. Barriers to preoperative malnutrition screening were assessed using the Capability Opportunity Motivation-Behaviour model. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed using summative content analysis. Of the 225 HCPs surveyed (n = 111 dietitians, n = 72 physicians, n = 42 allied HCPs), 96%-100% agreed that preoperative malnutrition is a modifiable risk factor associated with worse surgical outcomes and is a treatment priority. Yet, 65% (n = 142/220; dietitians: 88% vs. physicians: 40%) reported screening for malnutrition, which mostly occured in the postoperative period (n = 117) by dietitians (n = 94). Just 42% (48/113) of non-dietitian respondents referred positively screened patients to a dietitian for further assessment and treatment. The most prevalent barriers for malnutrition screening were related to opportunity, including availability of resources (57%, n = 121/212), time (40%, n = 84/212) and support from others (38%, n = 80/212). In conclusion, there is a gap between opinion and practice among surgical HCPs pertaining to malnutrition. Although HCPs agreed malnutrition is a surgical priority, the opportunity to screen for nutrition risk was a great barrier.

Neuraxial Anesthesia for Combined Left Nephrectomy and Left Hemicolectomy in a One-Lung Patient

Monopulmonary patients undergoing major abdominal surgery represent a high-risk population. While general anesthesia is typically the standard approach, mechanical ventilation can cause significant complications, particularly in patients with pre-existing lung conditions. Tailored anesthesia strategies are essential to mitigate these risks and preserve respiratory function. We present the case of a 71-year-old female with a history of prior right pneumonectomy for lung cancer. She was scheduled for combined left nephrectomy and left hemicolectomy laparotomic surgery because of extended colon cancer. The patient was prepared according to the local Enhanced Recovery After Surgery (ERAS) protocol and underwent thoracic neuraxial anesthesia with sedation maintaining spontaneous breathing, so avoiding general anesthesia and mechanical ventilation. Anesthesia in the surgical field was effective, and no respiratory problems occurred intraoperatively. The patient's rapid recovery and early discharge underscore the success of our "tailored anesthesia strategy." Our experience highlights the feasibility and benefits of tailored anesthesia in monopulmonary patients undergoing major abdominal surgery. By avoiding general anesthesia and mechanical ventilation, we mitigated risks and optimized patient outcomes, emphasizing the importance of individualized approaches in high-risk surgical populations.

Postoperative nutrition in the setting of enhanced recovery programmes

Patients undergoing major surgery for gastrointestinal cancer are at high risk of developing or worsening malnutrition and sarcopenia. In malnourished patients, preoperative nutritional support may not be sufficient and so postoperative support is advised. This narrative review addresses several aspects of postoperative nutritional care in the setting of enhanced recovery programmes. Early oral feeding, therapeutic diet, oral nutritional supplements, immunonutrition, and probiotics are discussed. When postoperative intake is insufficient, nutritional support favouring the enteral route is recommended. Whether this approach should use a nasojejunal tube or jejunostomy is still a matter of debate. In the setting of enhanced recovery programmes with early discharge, nutritional follow-up and care should be continued beyond the short time in hospital. In enhanced recovery programmes, the main specific aspects of nutrition are patient education, early oral intake, and post-discharge care. The other aspects do not differ from conventional care.

Lessons following implementation of a colorectal enhanced recovery after surgery (ERAS) protocol in a rural hospital setting

INTRODUCTION

Enhanced recovery after surgery (ERAS) programs have become increasingly popular in the management of patients undergoing colorectal resection. However, the validity of ERAS in rural hospital settings without intensive care facilities has not been primarily evaluated. This study aimed to assess an ERAS protocol in a rural surgical department based in Invercargill New Zealand.

METHODS

Ten years of prospectively collected data were analysed retrospectively from an ERAS database of all patients undergoing open, converted, or laparoscopic colorectal resections. Data were collected between two time periods: before the implementation of an ERAS protocol, from January 2011 to December 2013; as well as after the implementation of an ERAS protocol, from January 2014 to December 2020. The primary outcome measures were hospital length of stay (LOS) and LOS in the critical care unit (LOS-CCU). Secondary outcomes were compliance with ERAS protocol, mortality, readmission, and reoperation rates.

RESULTS

A total of 118 and 558 colorectal resections were performed in the pre-ERAS and ERAS groups respectively. A statistically significant reduction in hospital LOS was achieved from a median of 8 to 7 days (P = 0.038) when comparing pre-ERAS to ERAS groups respectively. Furthermore, a significant reduction in re-operation rates was observed (7.6% vs. 3% in the ERAS group, P = 0.033) which was seen without a rise in readmission rates (13.6% vs. 13.6% in the ERAS group).

CONCLUSION

The implementation of ERAS in a rural surgical setting is feasible, and these initial findings suggest ERAS adds value in optimizing the colorectal patient's surgical journey.

ESPEN Guidelines on Clinical nutrition in surgery - Special issues to be revisited

The ESPEN Guidelines on Clinical nutrition in Surgery from 2017 has been also available as practical guideline with algorithms since 2021 (www.espen.org). An update will be perfomed in the near future. This review focuses on recent data with regard to special issues and topics to be revisited in the guidelines: These are nutritional assessment, sarcopenic obesity, prehabilitation, oral/enteral immunonutrition, postoperative oral supplementation in hospital and after discharge.

Multicomponent perioperative interventions to improve outcomes for frail patients: a systematic review

BACKGROUND

Preoperative frailty is associated with increased risk of adverse outcomes. In 2017, McIsaac and colleagues' systematic review found that few interventions improved outcomes in this population and evidence was low-quality. We aimed to systematically review the evidence for multicomponent perioperative interventions in frail patients that has emerged since McIsaac et al.'s review.

METHODS

PUBMED, EMBASE, Cochrane, and CINAHL databases were searched for English-language studies published since January 1, 2016, that evaluated multicomponent perioperative interventions in patients identified as frail. Quality was assessed using the National Institute of Health Quality Assessment Tool. A narrative synthesis of the extracted data was conducted.

RESULTS

Of 2835 articles screened, five studies were included, all of which were conducted in elective oncologic gastrointestinal surgical populations. Four hundred and thirteen patients were included across the five studies and the mean/median age ranged from 70.1 to 87.0 years. Multicomponent interventions were all applied in the preoperative period. Two studies also applied interventions postoperatively. All interventions addressed exercise and nutritional domains with variability in timing, delivery, and adherence. Multicomponent interventions were associated with reduced postoperative complications, functional deterioration, length of stay, and mortality. Four studies reported on patient-centred outcomes. The quality of evidence was fair.

CONCLUSIONS

This systematic review provides evidence that frail surgical patients undergoing elective oncologic gastrointestinal surgery may benefit from targeted multicomponent perioperative interventions. Yet methodological issues and substantial heterogeneity of the interventions precludes drawing clear conclusions regarding the optimal model of care. Larger, low risk of bias studies are needed to evaluate optimal intervention delivery, effectiveness in other populations, implementation in health care settings and ascertain outcomes of importance for frail patients and their carers.

Comparison of early surgical outcomes of robotic and laparoscopic colorectal cancer resection reported by a busy district general hospital in England

Robotic platforms provide a stable tool with high-definition views and improved ergonomics compared to laparoscopic approaches. The aim of this retrospective study was to compare the intra- and short-term postoperative results of oncological resections performed robotically (RCR) and laparoscopically (LCR) at a single centre. Between February 2020 and October 2022, retrospective data on RCR were compared to LCR undertaken during the same period. Parameters compared include total operative time, length of stay (LOS), re-admission rates, 30-day morbidity. 100 RCR and 112 LCR satisfied inclusion criteria. There was no difference between the two group's demographic and tumour characteristics. Overall, median operative time was shorter in LCR group [200 vs. 247.5 min, p < 0.005], but this advantage was not observed with pelvic and muti-quadrant resections. There was no difference in the rate of conversion [5(5%) vs. 5(4.5%), p > 0.95]. With respect to perioperative outcomes, there was no difference in the overall morbidity, or mortality between RCR and LCR, in particular requirement for blood transfusion [3(3%) vs. 5(4.5%), p 0.72], prolonged ileus [9(9%) vs. 15(13.2%), p 0.38], surgical site infections [5(4%) vs. 5(4.4%), p > 0.95], anastomotic leak [7(7%) vs. 5(4.4%), p 0.55], and re-operation rate [9(9%) vs. 7(6.3%), p 0.6]. RCR had shorter LOS by one night, but this did not reach statistical significance. No difference was observed in completeness of resection but there was a statically significant increase in lymph node harvest in the robotic series. Robotic approach to oncological colorectal resections is safe, with comparable intra- and peri-operative morbidity and mortality to laparoscopic surgery.

Influence of motivational interviewing on postoperative mobilization in the enhanced recovery after surgery (ERAS®) pathway in elective colorectal surgery - a randomized patient-blinded pilot study

PURPOSE

Early mobilization is an essential component of the Enhanced Recovery after Surgery (ERAS®)-pathway. However, a large percentage of patients fail to achieve the ERAS® recommended goal (360 min out of bed from post-operative day 1/POD1). Motivational Interviewing (MI) is an evidence-based type of patient-centered consultation to promote intrinsic motivation. This study aims to evaluate if MI can improve postoperative mobilization.

METHODS

This two-arm, patient-blinded pilot randomized controlled trial included ERAS®-patients undergoing elective bowel resections. Conversations were validated by MI Treatment Integrity. Two validated motion sensors (movisens) and self-assessments were used to measure mobilization (POD1-POD3: Time out of bed, time on feet and step count).

RESULTS

97 patients were screened, 60 finally included and randomized. Cumulatively across POD1-3, the intervention group (IG) was longer out of bed than the control group (CG) (median: 685 vs. 420 min; p=0.022). The IG achieved the ERAS®-goal of 360 min/day more frequently across POD1-3 (27.4% vs. 10.61%; p=0.013). Time on feet was 131.5 min/day (median per POD) in IG vs. 95.8 min/day in the CG (p=0.212), step count was 1347 in IG vs. 754 steps/day in CG (p=0.298).

CONCLUSION

MI could be conducted low threshold and was well accepted by patients. MI can improve mobilization in the context of ERAS®. Despite better performance, it should be noted that only 27.4% of the IG reached the ERAS®-compliance goal of 360 min/day. The findings of this pilot study stipulate to further test the promising perioperative effects of MI within a multicenter superiority trial.

REGISTRATION

This study was registered prospectively in the German Clinical Trials Register on 25.02.2022. Trial registration number is "DRKS00027863".

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

BACKGROUND

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

PATIENTS AND METHODS

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

RESULTS

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

CONCLUSION

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

Bowel preparation for elective colorectal resection: multi-treatment machine learning analysis on 6241 cases from a prospective Italian cohort

BACKGROUND

Current evidence concerning bowel preparation before elective colorectal surgery is still controversial. This study aimed to compare the incidence of anastomotic leakage (AL), surgical site infections (SSIs), and overall morbidity (any adverse event, OM) after elective colorectal surgery using four different types of bowel preparation.

METHODS

A prospective database gathered among 78 Italian surgical centers in two prospective studies, including 6241 patients who underwent elective colorectal resection with anastomosis for malignant or benign disease, was re-analyzed through a multi-treatment machine-learning model considering no bowel preparation (NBP; No. = 3742; 60.0%) as the reference treatment arm, compared to oral antibiotics alone (oA; No. = 406; 6.5%), mechanical bowel preparation alone (MBP; No. = 1486; 23.8%), or in combination with oAB (MoABP; No. = 607; 9.7%). Twenty covariates related to biometric data, surgical procedures, perioperative management, and hospital/center data potentially affecting outcomes were included and balanced into the model. The primary endpoints were AL, SSIs, and OM. All the results were reported as odds ratio (OR) with 95% confidence intervals (95% CI).

RESULTS

Compared to NBP, MBP showed significantly higher AL risk (OR 1.82; 95% CI 1.23-2.71; p = .003) and OM risk (OR 1.38; 95% CI 1.10-1.72; p = .005), no significant differences for all the endpoints were recorded in the oA group, whereas MoABP showed a significantly reduced SSI risk (OR 0.45; 95% CI 0.25-0.79; p = .008).

CONCLUSIONS

MoABP significantly reduced the SSI risk after elective colorectal surgery, therefore representing a valid alternative to NBP.
