Enhanced recovery program versus conventional care after colorectal surgery in the geriatric population: a systematic review and meta-analysis

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.

Ketamine intolerance in patients on enhanced recovery after surgery protocols undergoing colorectal operations

BACKGROUND

Ketamine is used in enhanced recovery after surgery (ERAS) protocols because of its beneficial antihyperalgesic and antitolerance effects. However, adverse effects such as hallucinations, sedation, and diplopia could limit ketamine's utility. The main objective of this study was to identify rates of ketamine side effects in postoperative patients after colorectal surgery and, secondarily, to compare short-term outcomes between patients receiving ketamine analgesia and controls.

METHODS

This was a retrospective observational cohort study. Subjects were adults who underwent ERAS protocol-guided colorectal surgery at a large, integrated health system. Patients were grouped into ketamine-receiving and preketamine cohorts. Patients receiving ketamine were divided into tolerant and intolerant groups. Propensity score-adjusted models tested multivariate associations of ketamine tolerance/intolerance vs control group.

RESULTS

A total of 732 patients underwent colorectal surgery within the ERAS program before ketamine's introduction (control). After ketamine's introduction, 467 patients received the medication. Intolerance was seen in 29% of ketamine recipients, and the most common side effect was diplopia. Demographics and surgical variables did not differ between cohorts. Multivariate models revealed no significant differences in hospital stays. Pain scores in the first 24 hours after surgery were slightly higher in patients receiving ketamine. Opiate consumption after surgery was lower for both ketamine tolerant and ketamine intolerant cohorts than for controls.

CONCLUSION

Rates of ketamine intolerance are high, which can limit its use and potential effectiveness. Ketamine analgesia significantly reduced opiate consumption without increasing hospital stays after colorectal surgery, regardless of whether it was tolerated.

The enhanced recovery after surgery (ERAS) protocol implementation in a national tertiary-level hospital: a prospective cohort study

Introduction

Successful colorectal surgery is determined based on postoperative mortality and morbidity rates, complication rates, and cost-effectiveness. One of the methods to obtain an excellent postoperative outcome is the enhanced recovery after surgery (ERAS) protocol. This study aims to see the effects of implementing an ERAS protocol in colorectal surgery patients.

Methods

Eighty-four patients who underwent elective colorectal surgery at National Tertiary-level Hospital were included between January 2021 and July 2022. Patients were then placed into ERAS (42) and control groups (42) according to the criteria. The Patients in the ERAS group underwent a customized 18-component ERAS protocol and were assessed for adherence. Postoperatively, both groups were monitored for up to 30 days and assessed for complications and readmission. The authors then analyzed the length of stay and total patient costs in both groups.

Results

The length of stay in the ERAS group was shorter than the control group [median (interquartile range) 6 (5-7) vs. 13 (11-19), P<0.001], with a lower total cost of [USD 1875 (1234-3722) vs. USD 3063 (2251-4907), P<0.001]. Patients in the ERAS group had a lower incidence of complications, 10% vs. 21%, and readmission 5% vs. 10%, within 30 days after discharge than patients in the control group; however, the differences were not statistically significant. The adherence to the ERAS protocol within the ERAS group was 97%.

Conclusion

Implementing the ERAS protocol in colorectal patients reduces the length of stay and total costs.

The safety and effectiveness of enhanced recovery after surgery (ERAS) in older patients undergoing orthopedic surgery: a systematic review and meta-analysis

INTRODUCTION

To systematically review and analyze the safety and effectiveness of ERAS in older patients undergoing orthopedic surgeries.

MATERIALS AND METHODS

We searched PubMed, EMBASE, CINAHL, MEDLINE (Ovid), Web of Science, the Cochrane Library, and other databases to identify all randomized controlled studies and cohorts. We used the Cochrane Risk of Bias Assessment Tool and the Newcastle‒Ottawa Scale to assess the study quality. A meta-analysis was performed using the inverse variance weighting method.

RESULTS

This study included 15 studies involving a total of 2591 older patients undergoing orthopedic surgeries with 1480 in the ERAS group. The ERAS group had a lower incidence of postoperative complications than the control group (RR 0.52; 95% CI 0.42-0.65). Length of stay was 3.37 days lower in the ERAS group than in the control group (P < 0.01). And the ERAS protocol reduced the patient's postoperative VAS score (P < 0.01). Meanwhile, there was a lack of evidence of significant differences between the ERAS group and the control group in total bleeding and 30-day readmission rate.

CONCLUSIONS

The implementation of the ERAS program in older patients undergoing orthopedic surgeries is safe and effective. However, there is still a lack of standardization of protocols across institutions and centers for orthopedic surgery for older patients. Identifying ERAS components that are beneficial to older patients and developing ERAS protocols that are appropriate for older adults may further improve outcomes.

Same-day discharge (SDD) vs standard enhanced recovery after surgery (ERAS) protocols for major colorectal surgery: a systematic review

BACKGROUND

Enhanced recovery after surgery (ERAS) programs are well-established, resulting in improved outcomes and shorter length of hospital stay (LOS). Same-day discharge (SDD), or "hyper-ERAS", is a natural progression of ERAS. This systematic review aims to compare the safety and efficacy of SDD against conventional ERAS in colorectal surgery.

METHODS

The protocol was prospectively registered in PROSPERO (394793). A systematic search was performed in major databases to identify relevant articles, and a narrative systematic review was performed. Primary outcomes were readmission rates and length of hospital stay (LOS). Secondary outcomes were operative time and blood loss, postoperative pain, morbidity, nausea or vomiting, and patient satisfaction. Risks of bias was assessed using the ROBINS-I tool.

RESULTS

Thirteen studies were included, with five single-arm and eight comparative studies, of which one was a randomised controlled trial. This comprised a total of 38,854 patients (SDD: 1622; ERAS: 37,232). Of the 1622 patients on the SDD pathway, 1590 patients (98%) were successfully discharged within 24 h of surgery. While most studies had an overall low risk of bias, there was considerable variability in inclusion criteria, types of surgery or anaesthesia, and discharge criteria. SDD resulted in a significantly reduced postoperative LOS, without increasing risk of 30-day readmission. Intraoperative blood loss and postoperative morbidity rates were comparable between both groups. Operative duration was shorter in the SDD group. Patient-reported satisfaction was high in the SDD cohort.

CONCLUSION

SDD protocols appear to be safe and feasible in selected patients undergoing major colorectal operations. Randomised controlled trials are necessary to further substantiate these findings.

Perioperative Nutritional Considerations in Colon and Rectal Surgery

Malnutrition is common in surgical patients and is associated with substantially increased morbidity and mortality. Dedicated assessment of nutritional status is advised by major nutrition and surgical societies. Assessment may utilize comprehensive and validated nutritional assessment tools or targeted history, physical examination with accompanying serologic markers to identify nutritional risk preoperatively. Emergent surgery in malnourished patients should proceed as the clinical situation dictates with consideration of ostomy or primary anastomosis with proximal fecal diversion to mitigate postoperative infectious complications. Nonemergent surgery should be delayed to facilitate nutritional optimization via oral nutritional supplementation preferably and total parenteral nutrition if necessary for at least 7 to 14 days. Exclusive enteral nutrition may be considered to optimize nutritional status and inflammation in patients with Crohn's disease. Immunonutrition use in the preoperative setting is not supported by evidence. Perioperative and postoperative immunonutrition may be of benefit but requires dedicated study in the contemporary era. Close attention to preoperative nutritional status and optimization represents a critical opportunity to improve outcomes in patients undergoing colorectal surgery.

Enhanced recovery pathway in open and minimally invasive colorectal cancer surgery: a prospective study on feasibility, compliance, and outcomes in a high-volume resource limited tertiary cancer center

BACKGROUND

Enhanced recovery program (ERP) has demonstrated improved postoperative outcomes with increased compliance to pathway. However, there is scarce data on feasibility and safety in resource limited setting. The objective was to assess compliance with ERP and its impact on postoperative outcomes and return to intended oncological treatment (RIOT).

METHODS

A single center prospective observational audit was conducted from 2014 to 2019, in elective colorectal cancer surgery. Before implementation, multi-disciplinary team was educated regarding ERP. Compliance to ERP protocol and its elements was recorded. Impact of quantum of compliance (≥80% vs. <80%) to ERP on postoperative morbidity, mortality, readmission, stay, re-exploration, functional GI recovery, surgical-specific complications, and RIOT was evaluated for open and minimal invasive surgery (MIS).

RESULTS

During study, 937 patients underwent elective colorectal cancer surgery. Overall compliance with ERP was 73.3%. More than 80% compliance was observed in 332 (35.4%) patients in the entire cohort. Patients with <80% compliance had significantly higher overall, minor and surgery-specific complications, longer postoperative stay, delayed functional GI recovery for both open and MIS procedures. RIOT was observed in 96.5% patients. Duration to RIOT was significantly shorter following open surgery with ≥80% compliance. Compliance <80% to ERP was identified as one of the independent predictors for developing postoperative complications.

CONCLUSION

The study demonstrates beneficial impact of increased compliance to ERP on postoperative outcomes following open and minimally invasive surgery for colorectal cancer. Within a resource limited setting, ERP was found to feasible, safe, and effective in both open and minimally invasive colorectal cancer surgery.

Clinical practice guidelines for enhanced recovery after colon and rectal surgery from the American Society of Colon and Rectal Surgeons and the Society of American Gastrointestinal and Endoscopic Surgeons

The American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) are dedicated to ensuring high-quality innovative patient care for surgical patients by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus as well as minimally invasive surgery. The ASCRS and SAGES society members involved in the creation of these guidelines were chosen because they have demonstrated expertise in the specialty of colon and rectal surgery and enhanced recovery. This consensus document was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus and develop clinical practice guidelines based on the best available evidence. While not proscriptive, these guidelines provide information on which decisions can be made and do not dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, healthcare workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. These guidelines should not be deemed inclusive of all proper methods of care nor exclusive of methods of care reasonably directed toward obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all the circumstances presented by the individual patient. This clinical practice guideline represents a collaborative effort between the American Society of Colon and Rectal Surgeons (ASCRS) and the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and was approved by both societies.

AUGS-IUGA Joint Clinical Consensus Statement on Enhanced Recovery After Urogynecologic Surgery: Developed by the Joint Writing Group of the International Urogynecological Association and the American Urogynecologic Society. Individual writing group members are noted in the Acknowledgements section

INTRODUCTION AND HYPOTHESIS

Enhanced recovery after surgery (ERAS) evidence-based protocols for perioperative care can lead to improvements in clinical outcomes and cost savings. This article aims to present consensus recommendations for the optimal perioperative management of patients undergoing urogynecological surgery.

METHODS

A review of meta-analyses, randomized clinical trials, large nonrandomized studies, and review articles was conducted via PubMed and other databases for ERAS and urogynecological surgery. ERAS protocol components were established, and then quality of the evidence was both graded and used to form consensus recommendations for each topic. These recommendations were developed and endorsed by the writing group, which is comprised of the American Urogynecologic Society and the International Urogynecological Association members.

RESULTS

All recommendations on ERAS protocol items are based on best available evidence. The level of evidence for each item is presented accordingly. The components of ERAS with a high level of evidence to support their use include fasting for 6 h and taking clear fluids up to 2 h preoperatively, euvolemia, normothermia, surgical site preparation, antibiotic and antithrombotic prophylaxis, strong antiemetics and dexamethasone to reduce postoperative nausea and vomiting, multimodal analgesia and restrictive use of opiates, use of chewing gum to reduce ileus, removal of catheter as soon as feasible after surgery and avoiding systematic use of drains/vaginal packs.

CONCLUSIONS

The evidence base and recommendations for a urogynecology-relevant ERAS perioperative care pathway are presented in this consensus review. There are several elements of ERAS with strong evidence of benefit in urogynecological surgery.

Framework, component, and implementation of enhanced recovery pathways

The introduction of enhanced recovery pathways (ERPs) has led to a considerable paradigm shift towards evidence-based, multidisciplinary perioperative care. Such pathways are now widely implemented in a variety of surgical specialties, with largely positive results. In this narrative review, we summarize the principles, components and implementation of ERPs, focusing on recent developments in the field. We also discuss ‘special cases’ in ERPs, including: surgery in frail patients; emergency procedures; and patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2/COVID-19).

Optimized perioperative management (fast-track, ERAS) to enhance postoperative recovery in elective colorectal surgery

Aim

This manuscript provides information on the history, principles, and clinical results of Fast-track or ERAS concepts to optimize perioperative management (OPM).

Methods

With the focus on elective colorectal surgery description of the OPM concept and its elements for with special attention to the prevention of infectious complications and clinical results compared to traditional care will be given using recent systematic literature reviews. Additionally, clinical results for other major abdominal procedures are given.

Results

An optimized perioperative management protocol for elective colorectal resections will currently consist of 25 perioperative elements. These elements include the time from before hospital admission (patient education, screening, and treatment of possible risk factors like anemia, malnutrition, cessation of nicotine or alcohol abuse, optimization of concurrent systemic disease, physical prehabilitation, carbohydrate loading, adequate bowel preparation) to the preoperative period (shortened fasting, non-sedative premedication, prophylaxis of PONV and thromboembolic complications), intraoperative measures (systemic antibiotic prophylaxis, standardized anesthesia, normothermia and normovolemia, minimally invasive surgery, avoidance of drains and tubes) as well as postoperative actions (early oral feeding, enforced mobilization, early removal of a urinary catheter, stimulation of intestinal propulsion, control of hyperglycemia). Most of these elements are based on high-level evidence and will also have effects on the incidence of postoperative infectious complications.

Conclusion

Optimized perioperative management should be mandatory for elective surgery today as it enhances postoperative patient recovery, reduces morbidity and infectious complications.

Association of frailty with outcomes after elective colon resection for diverticular disease

BACKGROUND

Frailty has been associated with greater postoperative morbidity and mortality but its impact has not been investigated in patients with diverticulitis undergoing elective colon resection. Therefore, the present study examined the association of frailty with perioperative outcomes following elective colectomy for diverticular disease.

METHODS

The 2017-2019 American College of Surgeons-National Surgical Quality Improvement Program data registry was queried to identify patients (aged ≥18 years) undergoing elective colon resection for diverticular disease. The 5-factor modified frailty index (mFI-5) was used to stratify patients into non-frail (mFI 0), prefrail (mFI 1), and frail (mFI ≥2) cohorts. Major adverse events, surgical site infection, and postoperative ileus as well as prolonged length of stay, nonhome discharge, and unplanned readmission were evaluated using multivariable logistic models.

RESULTS

Of the 20,966 patients, 10.0% were frail. Compared to others, frail patients were generally older (non-frail: 55 years, [46-63], prefrail: 62, [54-70], frail: 64, [57-71]) and more commonly female (non-frail: 53.1%, prefrail: 58.6, frail: 64.4, P < .001). Frail patients more frequently underwent open colectomy and stoma creation compared with others. Frailty was associated with greater adjusted odds of major adverse event (adjusted odds ratio 1.25, 95% confidence interval 1.06-1.48), surgical site infection (adjusted odds ratio 1.28, 95% confidence interval 1.06-1.54), and postoperative ileus (adjusted odds ratio 1.59, 95% confidence interval 1.27-1.98). Similarly, frailty portended greater odds of prolonged length of stay, nonhome discharge, and unplanned readmission.

CONCLUSION

Frailty as defined by the mFI-5 was associated with greater morbidity and hospital resource use. Deployment of frailty instruments may augment traditional risk calculators and improve patient selection for elective colectomy.

Prevention and Management of Postoperative Ileus: A Review of Current Practice

Postoperative ileus (POI) has long been a challenging clinical problem for both patients and healthcare physicians alike. Although a standardized definition does not exist, it generally includes symptoms of intolerance to diet, lack of passing stool, abdominal distension, or flatus. Not only does prolonged POI increase patient discomfort and morbidity, but it is possibly the single most important factor that results in prolongation of the length of hospital stay with a significant deleterious effect on healthcare costs in surgical patients. Determining the exact pathogenesis of POI is difficult to achieve; however, it can be conceptually divided into patient-related and operative factors, which can further be broadly classified as neurogenic, inflammatory, hormonal, and pharmacological mechanisms.

Different strategies have been introduced aimed at improving the quality of perioperative care by reducing perioperative morbidity and length of stay, which include Enhanced Recovery After Surgery (ERAS) protocols, minimally invasive surgical approaches, and the use of specific pharmaceutical therapies. Recent studies have shown that the ERAS pathway and laparoscopic approach are generally effective in reducing patient morbidity with early return of gut function. Out of many studies on pharmacological agents over the recent years, alvimopan has shown the most promising results. However, due to its potential complications and cost, its clinical use is limited. Therefore, this article aimed to review the pathophysiology of POI and explore recent advances in treatment modalities and prevention of postoperative ileus.

Structured presurgery prehabilitation for aged patients undergoing elective surgery significantly improves surgical outcomes and reduces cost: A nonrandomized sequential comparative prospective cohort study

Background

With increasing global life expectancy, the number of major surgeries performed on aged adults invariably increases. This study aimed to examine the effectiveness of a structured prehabilitative program for aged colorectal cancer patients in improving short‐term surgical outcomes.

Methods

A prospective philanthropically sponsored Programme for Enhanced Elderly Recovery at Sengkang General Hospital (PEERS) was initiated in February 2017 for patients ≥70‐years‐old who were due to undergo elective colectomies. These patients were put through a 2‐ to 4‐week‐long program before surgery, which included geriatric assessment, nutrition supplementation, and resistance training. They were compared with patients from a similar age group before PEERS was introduced (non‐PEERS).

Results

Fifty‐eight patients, with a median age of 78.5 (70–93) years, were recruited from a single institution to undergo PEERS. Baseline characteristics between the groups were similar. There was no significant improvement of anthropometric and functional characteristics before and after PEERS. Duration of hospitalization was shorter in the PEERS group (9 vs 11 days, P = 0.01). Both groups had similar 30‐days’ morbidity rates (8.6% vs 17.4%, P = 0.26). The PEERS group had significant improvement in their median EuroQol‐5 Dimension score (0.70 presurgery to 0.80 6‐months’ postsurgery, P = 0.01). After multivariate analysis, the average duration of hospitalization in the PEERS group was 6.8 days shorter (P = 0.018; CI, 1.2–12.4) after adjusting for modality of surgery and complications. This represented a cost saving of USD$11,838.80.

Conclusion

A standardized prehabilitation program for aged adults reduced the duration of hospitalization, improved the quality of life after surgery, and reduced costs.

The impact of enhanced recovery program compliance after elective liver surgery: Results from a multicenter prospective national registry

BACKGROUND

The Enhanced Recovery Program after surgery is a multimodal, evidence-based protocol of care developed to minimize the response to surgical stress. Data on the influence of ERP on outcomes, particularly according to the complexity of liver surgery, are lacking.

METHODS

A prospective multicenter cohort of patients undergoing liver surgery and exposed to Enhanced Recovery Program from 2016 to 2020 in France was analyzed. High Enhanced Recovery Program compliance was defined as more than 70% of items (15 out of 21). The outcomes were the rate of complications, length of stay, and functional recovery according to Enhanced Recovery Program compliance.

RESULTS

A total of 297 patients were included in the study, and they had 61.9% overall compliance (median = 13 items, interquartile range 11-15). Complications were observed in 32.2% (n = 95) of cases, and the mean length of hospital stay was 7.28 (±7.15) days overall. A longer duration of liver surgery was associated with an increase in the complication rate, while high compliance was independently associated with a reduced risk of complications in the multivariable analysis.

CONCLUSION

High Enhanced Recovery Program compliance was associated with a lower rate of postoperative complexity.

[Enhanced recovery after surgery-Does the ERAS concept keep its promises]

INTRODUCTION

Perioperative enhanced recovery after surgery (ERAS) concepts or fast-track are supposed to accelerate recovery after surgery, reduce postoperative complications and shorten the hospital stay when compared to traditional perioperative treatment.

METHODS

Electronic search of the PubMed database to identify systematic reviews with meta-analysis (SR) comparing ERAS and traditional treatment.

RESULTS

The presented SR investigated 70 randomized controlled studies (RCT) with 12,986 patients and 93 non-RCT (24,335 patients) concerning abdominal, thoracic and vascular as well as orthopedic surgery. The complication rates were decreased under ERAS following colorectal esophageal, liver and pulmonary resections as well as after implantation of hip endoprostheses. Pulmonary complications were reduced after ERAS esophageal, gastric and pulmonary resections. The first bowel movements occurred earlier after ERAS colorectal resections and delayed gastric emptying was less often observed after ERAS pancreatic resection. Following ERAS fast-track esophageal resection, anastomotic leakage was diagnosed less often as well as surgical complications after ERAS pulmonary resection. The ERAS in all studies concerning orthopedic surgery and trials investigating implantation of a hip endoprosthesis or knee endoprosthesis reduced the risk for postoperative blood transfusions. Regardless of the type of surgery, ERAS shortened hospital stay without increasing readmissions.

CONCLUSION

Numerous clinical trials have confirmed that ERAS reduces postoperative morbidity, shortens hospital stay and accelerates recovery without increasing readmission rates following most surgical operations.
