Retrospective cohort study of an enhanced recovery programme in oesophageal and gastric cancer surgery

Impact of standardized clinical pathways on esophagectomy: a systematic review and meta-analysis

Esophageal surgery is historically associated with adverse postoperative outcomes. Selected high-volume centers have previously reported the effect on clinical outcomes following the adoption of a standardized clinical pathway (SCP). This meta-analysis aims to evaluate the current literature to document the effect of SCP and enhanced recovery after surgery (ERAS) on esophagectomy outcomes. A literature search was conducted through the main search engines (PubMed, Embase, Medline, and Cochrane database) in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. All eligible comparative studies (randomized control trial, prospective, retrospective, and combined) were identified and assessed based on Methodological Index for Non-Randomized Studies and Jadad quality criteria. Data concerning overall morbidity, early mortality, and length of stay (LOS) were primarily collected and compared. Secondary outcomes included anastomotic leaks, pulmonary complications, and readmission rate. Twenty-six articles (including five randomized controlled trials and six prospective trials) were included in the analysis. Overall study quality was moderate and the included studies utilized a variable approach to SCP. No statistically significant differences were found between groups in terms of overall morbidity, postoperative mortality, anastomotic leak, and readmission rates. Significant improvements included pulmonary complications (odds ratios [OR] 0.66, 95% confidence interval [CI] 0.49-0.94) and hospital LOS (OR -3.68, 95% CI -4.49 to -2.87). Previous reports of SCP within esophagectomy programs have demonstrated clinical improvements in postoperative pulmonary complications and LOS. Given the high heterogeneity historically demonstrated within SCPs, further improvement in outcomes should be expected following the adoption of standardized ERAS guidelines.

The efficacy of clinical pathway in gastric cancer surgery

Objectives

Clinical pathways are useful tools for surgical quality improvement and better peri-operative clinical outcomes for patients undergoing major surgery. This study aimed to evaluate the influence of clinical pathway on early postoperative outcomes for gastric cancer patients.

Material and Methods

The study was designed as a retrospective cohort observational study. Patients who had undergone curative gastrectomy for gastric cancer were evaluated by using the gastric cancer database, which was prospectively maintained. The patients were divided into two groups based on the date when the clinical pathway was first used: The control group (May 2015-May 2016) and the clinical pathway group (June 2016-December 2017). Early postoperative outcomes including the length of hospital stay, start of the day of diet, and 30-day complications including reoperation, and operative mortality were compared after propensity score matching.

Results

A total of 101 patients were analyzed, and the data of 70 patients (35 patients in each group) were compared after matching. Clinical pathway group demonstrated shorter hospital stay, earlier nasogastric tube removal, and start of earlier liquid/soft diet. Overall complication rate was lower in the clinical pathway group, while there was no statistically significant difference in major complication rates. No statistically significant difference was observed between the groups in terms of reoperation and operative mortality.

Conclusion

Clinical pathway may shorten the postoperative length of hospital stay and reduce the overall complication rate without increasing major morbidity in patients undergoing elective gastric cancer surgery.

Enhanced Recovery After Surgery (ERAS) Pathway in Esophagectomy: Is a Reasonable Prediction of Hospital Stay Possible?

OBJECTIVE

To assess whether perioperative variables or deviation from enhanced recovery after surgery (ERAS) items could be associated with delayed discharge after esophagectomy, and to convert them into a scoring system to predict it.

SUMMARY BACKGROUND DATA

ERAS perioperative pathways have been recently applied to esophageal resections. However, low adherence to ERAS items and high rates of protocol deviations are often reported.

METHODS

All patients who underwent esophagectomy between April 2012 and March 2017 were managed with a standardized perioperative pathway according to ERAS principles. The target length of stay was set at eighth postoperative day (POD). All significant variables at bivariate analysis were entered into a logistic regression to produce a predictive score. An initial validation of the score accuracy was carried out on a separate patient sample.

RESULTS

Two hundred eighty-six patients were included in the study. Multivariate regression analysis showed that American Society of Anesthesiology score ≥ 3, surgery duration > 255 min, "nonhybrid" esophagectomy, and failure to mobilize patients within 24 h from surgery were associated with delayed discharge. The logistic regression model was statistically significant (P < 0.001) and correctly classified 81.9% of cases. The sensitivity was 96.6%, and the specificity was 17.6%. The prediction score applied to 23 patients correctly identified 100% of those discharged after eighth POD.

CONCLUSIONS

The results of this study seem to be clinically meaningful and in line with those from other studies. The initial validation revealed good predictive properties.

Multicomponent hospital-led interventions to reduce hospital stay for older adults following elective surgery: a systematic review

Background

Elective older adult inpatient admissions are increasingly common. Older adults are at an elevated risk of adverse events in hospital, potentially increasing with lengthier hospital stay. Hospital-led organisational strategies may optimise hospital stay for elective older adult inpatients.

Objectives

To evaluate the effectiveness and cost-effectiveness of hospital-led multicomponent interventions to reduce hospital stay for older adults undergoing elective hospital admissions.

Data sources

Seven bibliographic databases (MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Health Management Information Consortium, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature and Allied and Complementary Medicine Database) were searched from inception to date of search (August 2017), alongside carrying out of web searches, citation searching, inspecting relevant reviews, consulting stakeholders and contacting authors. This search was duplicated, with an additional cost-filter, to identify cost-effectiveness evidence.

Review methods

Comparative studies were sought that evaluated the effectiveness or cost-effectiveness of relevant interventions in elective inpatients with a mean or median age of ≥ 60 years. Study selection, data extraction and quality assessment were completed independently by two reviewers. The main outcome was length of stay, but all outcomes were considered. Studies were sorted by procedure, intervention and outcome categories. Where possible, standardised mean differences or odds ratios were calculated. Meta-analysis was performed when multiple randomised controlled trials had the same intervention, treatment procedure, comparator and outcome. Findings were explored using narrative synthesis.

Findings

A total of 218 articles were included, with 80 articles from 73 effectiveness studies (n = 26,365 patients) prioritised for synthesis, including 34 randomised controlled trials conducted outside the UK and 39 studies from the UK, of which 12 were randomised controlled trials. Fifteen studies included cost-effectiveness data. The evidence was dominated by enhanced recovery protocols and prehabilitation, implemented to improve recovery from either colorectal surgery or lower limb arthroplasty. Six other surgical categories and four other intervention types were identified. Meta-analysis found that enhanced recovery protocols were associated with 1.5 days’ reduction in hospital stay among patients undergoing colorectal surgery (Cohen’sd = –0.51, 95% confidence interval –0.78 to –0.24;p < 0.001) and with 5 days’ reduction among those undergoing upper abdominal surgery (Cohen’sd = –1.04, 95% confidence interval –1.55 to –0.53;p < 0.001). Evidence from the UK was not pooled (owing to mixed study designs), but it echoed findings from the international literature. Length of stay usually was reduced with intervention or was no different. Other clinical outcomes also improved or were no worse with intervention. Patient-reported outcomes were not frequently reported. Cost and cost-effectiveness evidence came from 15 highly heterogeneous studies and was less conclusive.

Limitations

Studies were usually of moderate or weak quality. Some intervention or treatment types were under-reported or absent. The reporting of variance data often precluded secondary analysis.

Conclusions

Enhanced recovery and prehabilitation interventions were associated with reduced hospital stay without detriment to other clinical outcomes, particularly for patients undergoing colorectal surgery, lower limb arthroplasty or upper abdominal surgery. The impacts on patient-reported outcomes, health-care costs or additional service use are not well known.

Future work

Further studies evaluating of the effectiveness of new enhanced recovery pathways are not required in colorectal surgery or lower limb arthroplasty. However, the applicability of these pathways to other procedures is uncertain. Future studies should evaluate the implementation of interventions to reduce service variation, in-hospital patient-reported outcomes, impacts on health and social care service use, and longer-term patient-reported outcomes.

The evolution of fast track protocols after oesophagectomy

Fast track is a standardised goal directed patient's care pathway that aims to facilitate recovery following surgery. Currently, there are large variations in the fast track protocols used in oesophagectomy due to the complexity of the procedure. The objective of this systematic review is to assess the evolution of fast track protocols following oesophagectomy since its implementation and the resulting effect on postoperative outcomes. Relevant electronic databases were searched for studies assessing the clinical outcome from fast track in oesophagectomy and also those assessing the effects of the individual key components in fast track protocols. The search yielded twenty-three publications regarding fast track implementation in oesophagectomy. A pattern of consistent evolution in fast-track protocols was clearly demonstrated and these have shown variations in the core-identified components across the studies. However, evolution in fast track protocols over time showed, an overall improvement in length of stay, anastomotic leak, pulmonary complications and mortality over time. Thirty publications were included that evaluated specific components of fast track protocols, with an increasing trend towards addressing the nutritional aspect in oesophagectomy care in more recent years. The variations in the key components of fast track protocol of care identify the need for continued assessment and identification for areas of improvement. In the future incremental gains through focused improvements in key components will lend itself to even better postoperative outcomes and patient experience during oesophageal cancer treatment.

Is closed thoracic drainage tube necessary for minimally invasive thoracoscopic-esophagectomy?

Background

Closed thoracic drainage tube (CTDT) is a conventional treatment after esophagectomy, even after minimally invasive esophagectomy. Here, we report a single-center, retrospective study to explore the safety and necessity of CTDT after thoracoscopic-esophagectomy.

Methods

From October 2015 and August 2016, 50 patients were enrolled and underwent thoracoscopic-esophagectomy in semi-prone position by same surgical team. Perioperative demographic and surgical parameters, and patients' satisfaction with or without CTDT after thoracoscopic-esophagectomy were collected and analyzed.

Results

All eligible patients (18 patients without CTDT and 32 patients with CTDT) were successfully underwent thoracoscopic procedures without conversion to open approach or major intraoperative complications and perioperative death. The two groups, with similar demographic parameters, had no statistically difference in thoracic operation time, blood loss, ICU stay, postoperative mobilization and oral feeding, and hospital stay. Also, the incidence of postoperative complications was similar with or without CTDT after esophagectomy. But, no-CTDT group had better post-operative satisfaction, including less pain scale scoring and better Norton scoring.

Conclusions

This study demonstrated that the treatment of no-CTDT after the minimally invasive thoracoscopic-esophagectomy is safe and feasible, might reduce the work intensity of medical stuff and lead to a better patients' experience.

Poor performance in incremental shuttle walk and cardiopulmonary exercise testing predicts poor overall survival for patients undergoing esophago-gastric resection

INTRODUCTION

Esophageal and gastric cancer have a poor prognosis and surgical intervention is associated with considerable morbidity, highlighting the need for careful preoperative assessment. The Incremental Shuttle Walk Test (ISWT) and Cardiopulmonary exercise testing (CPET) can assess preoperative fitness. This study aims to investigate their correlation with both postoperative respiratory complications and overall survival.

PATIENTS AND METHODS

Patients were identified who underwent esophageal or gastric resections for cancer between 2010 and 2014 and had ISWT and/or CPET assessments. Tumor differentiation, stage, postoperative respiratory complications, and outcome were documented and then correlated with the results of the preoperative fitness assessments.

RESULTS

Neither the ISWT result, anaerobic threshold (AT) nor VO2 Max correlated well with perioperative complications. However, ISWT (p < 0.001), AT (p < 0.001) and VO2 Max (p < 0.001) all correlated strongly with overall survival. No patient with a score of less than 350 m on ISWT survived beyond 3 years. In a subset of patients with ISWT results both pre and post chemotherapy (n = 49), those that had an improvement in result had a 19% incidence of post-operative respiratory complications compared to 45% where the result did not change or declined, though due to small numbers this only approached significance (p = 0.08).

CONCLUSION

ISWT and CPET can be useful preoperative tools to predict overall survival for patients undergoing esophago-gastric resection. Furthermore, patients that improve their functional status during chemotherapy seem to do better than those where it remains static or declines.

The impact of fast track protocols in upper gastrointestinal surgery: A meta-analysis of observational studies

BACKGROUND

Fast track surgery has been implemented in colorectal procedures during the last decade and is accompanied by significant improvement in patient outcomes during the early postoperative period. However, to date, its adoption in upper gastrointestinal surgery remains a matter of debate. In this context, we aimed to summarize the existing evidence in the international literature.

MATERIALS AND METHODS

We searched Medline, Scopus, ClinicalTrials.gov and Cochrane Central Register databases for published randomized controlled trials. The meta-analysis was performed with the RevMan 5.3.5 software.

MAIN FINDINGS

Thirty studies were finally included in the present meta-analysis. The post-operative morbidity was not influenced by the implementation of fast track surgery (FTS) (OR 0.84, 95% CI 0.64-1.09). However, in cases treated with laparoscopic surgery fast track surgery seemed to reduce morbidity by 50% (p = .006). The overall mortality of patients was low in the majority of included studies and was not influenced by fast track surgery (OR 1.12, 95% CI 0.50-2.52). The duration of postoperative hospitalization was significantly reduced with the adoption of FTS (MD -2.24, 95% CI -2.63 to -1.85 days). Concurrently, the overall cost was significantly reduced in cases treated with FTS (MD -982.30, 95% CI -1367.68 to -596.91 U.S dollars).

CONCLUSION

According to the findings of our meta-analysis suggest that FTS seems to be safe in patients undergoing upper gastrointestinal surgery and reduce both the days of postoperative hospitalization and the overall cost. This observation should be taken into account in future recommendations to enhance the implementation of FTS protocols in current clinical practice.

Clinical significance of expression of proliferating cell nuclear antigen and E-cadherin in gastric carcinoma

AIM

to investigate the expression of proliferating cell nuclear antigen (PCNA) and E-cadherin in gastric carcinoma and to analyze their clinical significance.

METHODS

A total of 146 patients were selected for this study, including 38 patients with intestinal metaplasia, 42 with dysplasia, and 66 with primary gastric cancer. In addition, 40 patients with normal gastric tissues were selected as controls. The expression of PCNA and E-cadherin was detected by immunohistochemistry. Differences in PCNA and the E-cadherin labeling indexes among normal gastric mucosa, intestinal metaplasia, dysplasia, and gastric carcinoma were compared. Subjects with normal gastric tissues were assigned to a normal group, while gastric cancer patients were assigned to a gastric cancer group. The difference in PCNA and E-cadherin expression between these two groups was compared. The relationship between expression of PCNA and E-cadherin and clinicopathological features was also explored in gastric cancer patients. Furthermore, prognosis-related factors, as well as the expression of PCNA and E-cadherin, were analyzed in patients with gastric cancer to determine the 3-year survival of these patients.

RESULTS

The difference in PCNA and the E-cadherin labeling indexes among normal gastric mucosa, intestinal metaplasia, dysplasia, and gastric carcinoma was statistically significant (P < 0.05). During the transition of normal gastric mucosa to gastric cancer, the PCNA labeling index gradually increased, while the E-cadherin labeling index gradually decreased (P < 0.05). The PCNA labeling index was significantly higher and the E-cadherin labeling index was significantly lower in gastric cancer than in dysplasia (P < 0.05). The expression of PCNA was significantly higher in the gastric cancer group than in the normal group, but E-cadherin was weaker (P < 0.05). There was a negative correlation between the expression of PCNA and E-cadherin in gastric carcinoma (r = -0.741, P = 0.000). PCNA expression differed significantly between gastric cancer patients with and without lymph node metastasis and between patients at different T stages. E-cadherin expression also differed significantly between gastric cancer patients with and without lymph node metastasis (P < 0.05). High T stage and positive PCNA expression were risk factors for the prognosis of patients with gastric cancer (RR > 1), while the positive expression of E-cadherin was a protective factor (RR < 1). The sensitivity, specificity, and accuracy of PCNA positivity in predicting the 3-year survival of patients with gastric cancer were 93.33%, 38.89%, and 0.64, respectively; while these values for E-cadherin negativity were 80.0%, 41.67%, and 0.59, respectively. When PCNA positivity and E-cadherin negativity were combined, the sensitivity, specificity, and accuracy were 66.67%, 66.67%, and 0.67, respectively.

CONCLUSION

Combined detection of PCNA and E-cadherin can improve the accuracy of assessing the prognosis of patients with gastric cancer.

Enhanced recovery after surgery protocol in oesophageal cancer surgery: Systematic review and meta-analysis

Background

Enhanced Recovery After Surgery (ERAS) protocol are well established in many surgical disciplines, leading to decrease in morbidity and length of hospital stay. These multi-modal protocols have been also introduced to oesophageal cancer surgery. This review aimed to evaluate current literature on ERAS in oesophageal cancer surgery and conduct a meta-analysis on primary and secondary outcomes.

Methods

MEDLINE, Embase, Scopus and Cochrane Library were searched for eligible studies. We analyzed data up to May 2016. Eligible studies had to contain four described ERAS protocol elements. The primary outcome was overall morbidity. Secondary outcomes included length of hospital stay, specific complications, mortality and readmissions. Random effect meta-analyses were undertaken.

Results

Initial search yielded 1,064 articles. Thorough evaluation resulted in 13 eligible articles which were analyzed. A total of 2,042 patients were included in the analysis (1,058 ERAS group and 984 treated with traditional protocols). Analysis of overall morbidity as well as complication rate did not show any significant reduction. Non-surgical complications and pulmonary complications were significantly lower in the ERAS group, RR = 0.71 95% CI 0.62–0.80, p < 0.00001 and RR = 0.75, 95% CI 0.60–0.94, p = 0.01, respectively. Meta-analysis on length of stay presented significant reduction Mean difference = -3.55, 95% CI -4.41 to -2.69, p for effect<0.00001.

Conclusions

This systematic review with a meta-analysis on ERAS in oesophageal surgery indicates a reduction of non-surgical complications and no negative influence on overall morbidity. Moreover, a reduction in the length of hospital stay was presented.

The Development, Application and Analysis of an Enhanced Recovery Programme for Major Oesophagogastric Resection

BACKGROUND

Enhanced recovery programmes improve outcomes in surgery, but their implementation after upper gastrointestinal resection has been limited. The aim of this study was to compare short-term outcomes for patients undergoing oesophagogastric surgery in an enhanced recovery programme (EROS).

METHODS

EROS was developed after a multidisciplinary meeting by multiple rounds of revision. EROS was applied to all patients undergoing major upper GI resection at a university teaching hospital in the UK from 20/9/13, with data reviewed at 18/09/15. EROS was assessed to identify predictors for compliance.

RESULTS

One hundred six patients underwent major upper GI resection including 81 oesophagectomies, 24 gastrectomies and 1 colonic interposition graft. Major complications (Clavien Dindo ≥3) occurred in 12 patients with 1 in-hospital death. Thirty-five patients (44%) were discharged on target day 8 of the EROS programme. Age and complications were independently associated with missing this discharge target.

CONCLUSION

Enhanced recovery is feasible and safe after major upper gastrointestinal surgery.

Enhanced recovery after surgery programs versus traditional perioperative care in laparoscopic hepatectomy: A meta-analysis

OBJECTIVE

Enhanced recovery after surgery (ERAS) programs are a series of measures being taken during the perioperation to alleviate surgical stress and accelerate the recovery rate of patients. Although several studies reported the efficacy of ERAS in liver surgery, the role of ERAS in laparoscopic hepatectomy is still unclear. This meta-analysis is aimed to evaluate the efficacy and safety of ERAS programs versus traditional care in laparoscopic hepatectomy.

METHODS

We searched PubMed, EMBASE, the Cochrane Library, CNKI, Wang Fang Database and VIP Database for randomized controlled trials (RCTs) or clinical controlled trials (CCTs) concerning using ERAS in laparoscopic hepatectomy. Data collection ended in June 1st, 2016. The main end points were intraoperative blood loss, intraoperative blood transfusion, operative time, the cost of hospitalization, time to first flatus, the time to first diet after surgery, duration of postoperative hospital stay, total postoperative complication rate, gradeⅠcomplication rate, grade Ⅱ-Ⅴcomplication rate.

RESULTS

8 studies with 580 patients were eligible for analysis. There were 292 cases in ERAS group and 288 cases in traditional perioperative care (CTL) group. Compared with CTL group, ERAS group was associated with significantly accelerated of time to first diet after surgery (SMD = -1.79, 95%CI: -3.19 ∼ -0.38, P = 0.01), time to first flatus (MD = -0.51, 95%CI: -0.91 ∼ -0.12, P = 0.01). Meanwhile, it was associated with significantly decreased of duration of the postoperative hospital stay (MD = -3.31, 95%CI: -3.95 ∼ -2.67, P < 0.00001), cost of hospitalization (MD = -1.0, 95%CI: -1.49 ∼ -0.51, P < 0.0001), total postoperative complication rate (OR = 0.34, 95%CI: 0.15-0.75, P = 0.008), gradeⅠcomplication rate (OR = 0.37, 95%CI: 0.22-0.64, P = 0.0003) and gradeⅡ-Ⅴcomplication rate (OR = 0.49, 95%CI: 0.32-0.77, P = 0.002). Whereas there was no significantly difference in intraoperative blood loss (P > 0.05), intraoperative blood transfusion (P > 0.05), operative time (P > 0.05) between ERAS group and CTL group.

CONCLUSION

Application of ERAS in laparoscopic hepatectomy is safe and effective, and it could accelerate the postoperative recovery and lighten the financial burden of patients.
