Influence of the Enhanced Recovery After Surgery Protocol on Postoperative Inflammation and Short-term Postoperative Surgical Outcomes After Colorectal Cancer Surgery

Effect of different anesthetic modalities with multimodal analgesia on postoperative pain level in colorectal tumor patients

BACKGROUND

According to clinical data, a significant percentage of patients experience pain after surgery, highlighting the importance of alleviating postoperative pain. The current approach involves intravenous self-control analgesia, often utilizing opioid analgesics such as morphine, sufentanil, and fentanyl. Surgery for colorectal cancer typically involves general anesthesia. Therefore, optimizing anesthetic management and postoperative analgesic programs can effectively reduce perioperative stress and enhance postoperative recovery. The study aims to analyze the impact of different anesthesia modalities with multimodal analgesia on patients' postoperative pain.

AIM

To explore the effects of different anesthesia methods coupled with multi-mode analgesia on postoperative pain in patients with colorectal cancer.

METHODS

Following the inclusion criteria and exclusion criteria, a total of 126 patients with colorectal cancer admitted to our hospital from January 2020 to December 2022 were included, of which 63 received general anesthesia coupled with multi-mode labor pain and were set as the control group, and 63 received general anesthesia associated with epidural anesthesia coupled with multi-mode labor pain and were set as the research group. After data collection, the effects of postoperative analgesia, sedation, and recovery were compared.

RESULTS

Compared to the control group, the research group had shorter recovery times for orientation, extubation, eye-opening, and spontaneous respiration (P < 0.05). The research group also showed lower Visual analog scale scores at 24 h and 48 h, higher Ramany scores at 6 h and 12 h, and improved cognitive function at 24 h, 48 h, and 72 h (P < 0.05). Additionally, interleukin-6 and interleukin-10 levels were significantly reduced at various time points in the research group compared to the control group (P < 0.05). Levels of CD3+, CD4+, and CD4+/CD8+ were also lower in the research group at multiple time points (P < 0.05).

CONCLUSION

For patients with colorectal cancer, general anesthesia coupled with epidural anesthesia and multi-mode analgesia can achieve better postoperative analgesia and sedation effects, promote postoperative rehabilitation of patients, improve inflammatory stress and immune status, and have higher safety.

Challenging issues of implementing enhanced recovery after surgery programs in South Korea

This review discusses the challenges of implementing enhanced recovery after surgery (ERAS) programs in South Korea. ERAS is a patient-centered perioperative care approach that aims to improve postoperative recovery by minimizing surgical stress and complications. While ERAS has demonstrated significant benefits, its successful implementation faces various barriers such as a lack of manpower and policy support, poor communication and collaboration among perioperative members, resistance to shifting away from outdated practices, and patient-specific risk factors. This review emphasizes the importance of understanding these factors to tailor effective strategies for successful ERAS implementation in South Korea's unique healthcare setting. In this review, we aim to shed light on the current status of ERAS in South Korea and identify key barriers. We hope to encourage Korean anesthesiologists to take a leading role in adopting the ERAS program as the standard for perioperative care. Ultimately, our goal is to improve the surgical outcomes of patients using this proactive approach.

Initial experience of abdominal total mesorectal excision for rectal cancer using the da Vinci single port system

From November 2021 to February 2022, 15 patients underwent total abdominal mesorectal excision for rectal cancer using the da Vinci single port system. The clinical and pathological results were analyzed retrospectively. All surgeries were performed without conversion. The mean distance from the tumor to the anal verge was 10 cm (range, 2-15 cm). The mean operative time was 191 minutes, the median docking time was 4 minutes (range, 2-10 minutes), and the estimated blood loss was 20 mL (range, 20-50 mL). The mean number of lymph nodes harvested was 16.5, the mean distal resection margin was 3.52 cm, and all patients had circumferential and distal tumor-free resection margins. One patient had minor anastomotic leakage. The mean length of hospital stay was 5.8 ± 2.5 days. Abdominal total mesorectal excision using the da Vinci single port system for rectal cancer is technically feasible and safe, with acceptable pathological and short-term clinical outcomes.

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.

Multidisciplinary Treatment Strategy for Early Colon Cancer: A Review-An English Version

Treatment for early colon cancer has progressed rapidly, with endoscopic resection and minimally invasive surgery. It is important to select patients without risk of lymph node metastasis before deciding on endoscopic resection for early colon cancer treatment. Pathological risk factors include histologic grade of cancer cell differentiation, lymphovascular invasion, perineural invasion, tumor budding, and deep submucosal invasion. These risk factors for predicting lymph node metastasis are crucial for determining the treatment strategy of endoscopic excision and radical resection for early colon cancer. A multidisciplinary approach is emphasized to establish a treatment strategy for early colon cancer to minimize the risk of complications and obtain excellent oncologic outcomes by selecting an appropriate treatment optimized for the patient's stage and condition. Therefore, we aimed to review the optimal multidisciplinary treatment strategies, including endoscopy and surgery, for early colon cancer.

Robotic surgery for colorectal cancer

Background: Robotic surgical systems were created partly to solve several constraints of laparoscopic surgery and to offer technical advantages. With a substantial body of evidence demonstrating its efficacy in rectal cancer treatment, robotic surgery will soon become another conventional treatment. However, further investigations and randomized trials focusing on primary endpoints are necessary to establish some advantages of robot-assisted colon surgery.Current Concepts: Da Vinci Single-Site and SP platforms (Intuitive Surgical Inc.) were developed to overcome the shortcomings of single-port laparoscopic surgery. Despite the currently insufficient evidence, it seems that the SP platform addresses several limitations of single-port transabdominal or transanal surgery. Robotic transanal minimally invasive surgery and total mesorectal excision were developed to overcome conventional platforms’ limitations, using wristed instrumentation to enhance dexterity and ergonomics. Studies on the effectiveness and viability of this novel approach are ongoing. The near-infrared fluorescence technique, real-time stereotactic navigation technology, and other surgical data platforms based on artificial intelligence incorporated into the robotic system will play an important role in improving outcomes.Discussion and Conclusion: Robotic systems for advanced colorectal cancer offer technical advantages for complex and precise surgeries. If robotic surgery costs are reduced by expanding its indications and enhancing competition among different robotic platforms, it will provide clinical benefits to more patients and reduce social healthcare costs.

Multidisciplinary treatment strategy for early colon cancer

Background: Treatment for early colon cancer has progressed rapidly with endoscopic resection and minimally invasive surgery. Selection of patients without risk of lymph node metastasis is necessary before deciding on endoscopic resection for early colon cancer treatment. We aimed to review the optimal multidisciplinary treatment strategies for early colon cancer, including endoscopy and surgery.Current Concepts: Pathological risk factors include histologic grade of cancer cell differentiation, lymphovascular invasion, perineural invasion, tumor budding, and deep submucosal invasion. These risk factors for predicting lymph node metastasis are crucial for determining the treatment strategy of endoscopic excision and radical resection for early colon cancer. Prediction of the depth of invasion in early colon cancer using endoscopic optical assessments is vital to determine the appropriate treatment method for endoscopic or surgical resection. Furthermore, optical assessment of pit and vascular patterns is useful for estimating the depth of submucosal invasion using magnifying chromoendoscopy and narrow-band imaging endoscopy. Performing an endoscopic and pathologic evaluation of the risk factors for lymph node metastasis is imperative when selecting endoscopic or surgical resection. Endoscopic treatments include cold snare polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection. In addition, appropriate surgical treatment should be recommended for patients with early colon cancer with a high risk of lymph node metastasis.Discussion and Conclusion: A multidisciplinary approach should be recommended to establish an optimized treatment strategy, minimize the risk of complications, and obtain excellent oncologic outcomes via patienttailored treatment in patients with early colon cancer.

Effect of Enhanced Recovery after Surgery with Integrated Traditional Chinese and Western Medicine on Postoperative Stress Response of Patients with Gastrointestinal Tumors

Objective. To investigate the effect of enhanced recovery after surgery (ERAS) with integrated traditional Chinese and Western medicine on postoperative stress response of patients suffering from gastrointestinal tumors. Methods. A total of 74 patients with gastrointestinal tumors who underwent surgical treatment in our hospital from April 2019 to March 2021 were recruited and randomized into the control group and the observation group (1 : 1). The control group received routine treatment and care, while the observation group received ERAS plus integrated traditional Chinese and Western medicine. Clinical observation was performed regarding changes in preoperative mood and postoperative pain level in each group. Changes in expression levels of plasma cortisol, C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-β (TNF-β) before and after surgery were detected in each group. Time of patients’ first fart and defecation and complications after surgery in each group were recorded. Results. The visual analogue scale (VAS) of patients in the observation group after 12 and 24 h of surgery was significantly lower than that in the control group (12 h: observation group 2.0 (1.00, 3.00) vs. control group 4.00 (3.00, 5.00), $p=0.001$ ; 24 h: observation group 2.00 (1.00, 3.00) vs. control group 3.00 (2.00, 5.00), $p=0.005$ ). The preoperative anxiety degree of patients in the two groups was not statistically significant ( $p=0.489$ ). The plasma cortisol level of patients in the observation group after 24 and 48 h of surgery was significantly lower than that in the control group (24 h: observation group $426.54\pm 52.15$  nmol/L vs. control group $508.32\pm 41.08$  nmol/L, $p=0.001$ ; 48 h: observation group $287.19\pm 44.24$  nmol/L vs. control group $362.57\pm 43.46$  nmol/L, $p=0.001$ ). Patients’ postoperative CRP, IL-6, IL-8, and TNF-β expression levels in the observation group were remarkably lower than those in the control group at all time points. The first postoperative defecation came earlier in the observation group than that in the control group (observation group 76.00 h (64.50, 87.50) vs. control group 89.00 h (73.50, 116.00), $p=0.007$ ). There was 1 postoperative urinary tract infection in the observation group and 1 postoperative intestinal obstruction and 1 incisional wound infection in the control group. Conclusion. ERAS with integrated traditional Chinese and Western medicine could effectively reduce the postoperative stress response and inflammatory reaction in patients with gastrointestinal tumors, contributing to the safe and quick recovery of gastrointestinal functions of patients.

Association between enrollment in an enhanced recovery program for colorectal cancer surgery and long-term recurrence and survival

INTRODUCTION

Enhanced Recovery After Surgery (ERAS) programs have been shown to minimize the surgical inflammatory response in colorectal cancer. Our objective was to determine the association between an ERAS program for colorectal cancer surgery and oncologic recurrence and survival.

METHODS

A before-after intervention study was designed, including patients who underwent colorectal cancer surgery between November 2010 and March 2016. Cox hazard regression analysis was performed per cumulative year of follow-up to evaluate the association between ERAS program exposure and overall survival. Subgroup analysis was performed by cancer stage (low [I/II] vs. advanced [III/IV]).

RESULTS

In total, 646 patients were included, of which 339 were pre-ERAS and 307 were ERAS. Our overall median compliance rate with ERAS interventions was 90% (interquartile range: 85%-95%). Overall survival rates were higher in the ERAS group within the first 2 years after surgery (89.2% vs.  83.2%; p = 0.04). Multivariable analysis revealed that the ERAS enrollment was associated with a significantly lower risk in 5-year oncologic recurrence (adjusted hazard ratio [aHR]: 0.55; 95% confidence interval [CI]: 0.33-0.94; p = 0.03) and higher 3-year survival (aHR: 0.55; 95% CI: 0.33-0.93; p = 0.03) among patients with advanced cancer stage compared to pre-ERAS counterparts.

CONCLUSIONS

Patients with advanced colorectal cancer were less likely to suffer oncologic recurrence when managed during the ERAS period.

Implementation and improvement of Enhanced Recovery After Surgery protocols for colorectal cancer surgery

Purpose

Enhanced Recovery After Surgery (ERAS) reduces postoperative complications and shortens hospital stays. We aimed to describe the implementation and improvement of ERAS protocols in our institution through a multidisciplinary team approach.

Methods

A multidisciplinary team comprised of colorectal surgeons, anesthesiologists, nurses, pharmacists, nutritionists, and a performance improvement team was launched to develop the ERAS protocol. The ERAS protocol was followed in patients who underwent colonic and rectal surgery between January and November 2017. The ERAS protocol comprised 22 elements in the preoperative, intraoperative, and postoperative phases. After the initial application, ERAS compliance was monitored and audited every 4–6 months and improvements made as necessary.

Results

The length of hospital stay significantly decreased after the application of the ERAS protocols for colon cancer in 2017 and 2018. And there was no significant difference in the duration of hospital stay after applying the rectal cancer ERAS protocol. Moreover, after starting the colon ERAS, there was a significant decrease in the complication rate. Since December 2017, there was a continuous increase in the colorectal ERAS clinical pathway application rate, which remained high (>90%). The patient compliance rate significantly increased between 2017 and 2018, but slightly decreased again in 2019.

Conclusion

The application and continual improvement of an ERAS protocol are crucial. Improving compliance may result in better clinical outcomes. Additionally, the basic guidelines of ERAS must be applied and developed according to each hospital’s situation based on the team approach.

Enhanced recovery after surgery: importance of compliance audits

Background: The enhanced recovery after surgery (ERAS) protocol is associated with improved clinical outcomes. However, implementation of ERAS in clinical practice is difficult because it requires a multidisciplinary approach and complex standardization. Moreover, maintenance and auditing of ERAS protocols is another challenge.Current Concepts: The ERAS society provides guidelines for surgery in almost all areas, and each guideline consists of approximately 20 items. Audits are performed to determine whether the items are being applied appropriately in a compliant manner as well as monitor and improve ERAS protocols. Numerous studies have reported that even with the application of the same ERAS protocol, postoperative short-term outcomes such as reductions of hospital stay and postoperative complications were better in the high-compliance group than in the low-compliance group. In addition, some recent studies have reported that application of ERAS protocols with high compliance can improve the long-term survival outcomes in cancer patients. In this regard, ERAS has been hypothesized to improve long-term oncological outcomes by minimizing surgical stress and reducing the postoperative inflammatory response and damage to immune function.Discussion and Conclusion: In addition to the development of appropriate protocols, auditing of compliance is also an important part of ERAS implementation. High compliance may lead to improved clinical outcomes.
