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

Structured synchronous implementation of an enhanced recovery program in elective colonic surgery in 33 hospitals in The Netherlands

BACKGROUND

It has been clearly shown that after elective colorectal surgery patients benefit from multimodal perioperative care programs. The Dutch Institute for Health Care Improvement started a breakthrough project to implement a multimodal perioperative care program of enhanced recovery after surgery (ERAS). This pre/post noncontrolled study evaluated the success of large-scale implementation of the ERAS program for elective colonic surgery using the breakthrough series.

METHODS

A total of 33 hospitals participated in this breakthrough project during 2005-2009. Each hospital performed a retrospective chart review to gather information on traditionally treated patients (pre-ERAS group, n = 1,451). During the subsequent year patients were treated according to the ERAS program (ERAS group, n = 1 034). Outcomes were length of stay (LOS), functional recovery, adherence to the protocol, and determinants of reduced LOS.

RESULTS

Median LOS decreased significantly from 9 to 6 days (p < 0.001). In the ERAS group, functional recovery was reached within 3 days. Adherence to the protocol elements was high during the preoperative and perioperative phases but slightly lower during the postoperative phase. Younger age, female sex, American Society of Anesthesiologists grades I/II, and laparoscopic surgery were associated with decreased LOS. Care elements that positively influenced LOS were cessation of intravenous fluids and mobilization on postoperative day 1 and administration of laxatives postoperatively.

CONCLUSIONS

The ERAS program was successfully implemented in one-third of all Dutch hospitals using the breakthrough series. Participating hospitals reduced the LOS by a median 3 days and were able to improve their standard of care in elective colonic surgery.

Guidelines for perioperative care after radical cystectomy for bladder cancer: Enhanced Recovery After Surgery (ERAS(®)) society recommendations

PURPOSE

Enhanced recovery after surgery (ERAS) pathways have significantly reduced complications and length of hospital stay after colorectal procedures. This multimodal concept could probably be partially applied to major urological surgery.

OBJECTIVES

The primary objective was to systematically assess the evidence of ERAS single items and protocols applied to cystectomy patients. The secondary objective was to address a grade of recommendation to each item, based on the evidence and, if lacking, on consensus opinion from our ERAS Society working group.

EVIDENCE ACQUISITION

A systematic literature review was performed on ERAS for cystectomy by searching EMBASE and Medline. Relevant articles were selected and quality-assessed by two independent reviewers using the GRADE approach. If no study specific to cystectomy was available for any of the 22 given items, the authors evaluated whether colorectal guidelines could be extrapolated.

EVIDENCE SYNTHESIS

Overall, 804 articles were retrieved from electronic databases. Fifteen articles were included in the present systematic review and 7 of 22 ERAS items were studied. Bowel preparation did not improve outcomes. Early nasogastric tube removal reduced morbidity, bowel recovery time and length of hospital stay. Doppler-guided fluid administration allowed for reduced morbidity. A quicker bowel recovery was observed with a multimodal prevention of ileus, including gum chewing, prevention of PONV and minimally invasive surgery.

CONCLUSIONS

ERAS has not yet been widely implemented in urology and evidence for individual interventions is limited or unavailable. The experience in other surgical disciplines encourages the development of an ERAS protocol for cystectomy.

Does regional anaesthesia and analgesia or opioid analgesia influence recurrence after primary cancer surgery? An update of available evidence

Cancer continues to be a key cause of morbidity and mortality worldwide and its overall incidence continues to increase. Anaesthetists are increasingly faced with the challenge of managing cancer patients, for surgical resection to debulk or excise the primary tumour, or for surgical emergencies in patients on chemotherapy or for the analgesic management of disease- or treatment-related chronic pain. Metastatic recurrence is a concern. Surgery and a number of perioperative factors are suspected to accelerate tumour growth and potentially increase the risk of metastatic recurrence. Retrospective analyses have suggested an association between anaesthetic technique and cancer outcomes, and anaesthetists have sought to ameliorate the consequences of surgical trauma and minimise the impact of anaesthetic interventions. Just how anaesthesia and analgesia impact cancer recurrence and consequent survival is very topical, as understanding the potential mechanisms and interactions has an impact on the anaesthetist's ability to contribute to the successful outcome of oncological interventions. The outcome of ongoing, prospective, randomized trials are awaited with interest.

Fast-track surgery in intestinal deep infiltrating endometriosis

STUDY OBJECTIVE

To evaluate the length of hospital stay (LOS) and the readmission rate in patients undergoing laparoscopic surgery to treat intestinal deep infiltrating endometriosis (DIE) with application of the concepts of fast-track surgery.

DESIGN

Retrospective study of women undergoing laparoscopic treatment of intestinal DIE (Canadian Task Force classification II-3).

SETTING

Tertiary referral private hospital.

INTERVENTIONS

We evaluated 161 women who underwent laparoscopic surgery between January 2010 and April 2013 for complete treatment of intestinal DIE, via either conservative surgery (rectal shaving, mucosal skinning, or anterior disk resection) or radical surgery (segmental bowel resection). After surgery, all specimens were sent for pathologic examination to confirm the presence of endometriosis.

MEASUREMENTS AND MAIN RESULTS

Patients were divided into 2 groups according to type of surgery (conservative [n = 102] or radical [n = 59]), and LOS and readmission rate were measured in both groups. Median LOS was shorter in the conservative group compared with the segmental bowel resection group (19 vs 28 hours; p < .001). Ninety-two patients (90.2%) in the conservative surgery group were discharged to home on the first postoperative day, compared with only 38 patients (64.4%) in the segmental bowel resection group. Overall, the readmission rate was low (3.1%): 6.8% in the segmental bowel resection group and 1% in the conservative group (p = .04; odds ratio, 7.34; 95% confidence interval, 0.8-67.3); however, the need for repeat operation was similar in both groups (3.4% vs 1%; p = .28; odds ratio, 3.54; 95% confidence interval, 0.31-39.95).

CONCLUSION

Implementation of fast-track concepts in the laparoscopic treatment of intestinal DIE resulted in a short LOS and low readmission rate in both the segmental bowel resection and conservative surgery groups.

Reduction in length of stay for patients undergoing oesophageal and gastric resections with implementation of enhanced recovery packages

INTRODUCTION

The high mortality and morbidity associated with resection for oesophagogastric malignancy has resulted in a conservative approach to the postoperative management of this patient group. In August 2009 we introduced an enhanced recovery after surgery (ERAS) pathway tailored to patients undergoing resection for oesophagogastric malignancy. We aimed to assess the impact of this change in practice on standard clinical outcomes.

METHODS

Two cohorts were studied of patients undergoing resection for oesophagogastric malignancy before (August 2008 - July 2009) and after (August 2009 - July 2010) the implementation of the ERAS pathway. Data were collected on demographics, interventions, length of stay, morbidity and in-hospital mortality.

RESULTS

There were 53 and 55 oesophagogastric resections undertaken respectively for malignant disease in each of the study periods. The median length of stay for both gastric and oesophageal resection decreased from 15 to 11 days (Mann-Whitney U, p<0.001) following implementation of the ERAS pathway. There was no significant increase in morbidity (gastric resection 23.1% vs 5.3% and oesophageal resection 25.9% vs 16.7%) or mortality (gastric resection no deaths and oesophageal resection 1.8% vs 3.6%) associated with the changes. There was a significant decrease in the number of oral contrast studies used following oesophageal resection, with a reduction from 21 (77.8%) in 2008-2009 to 6 (16.7%) in 2009-2010 (chi-squared test, p<0.0001).

CONCLUSIONS

The introduction of an enhanced recovery programme following oesophagogastric surgery resulted in a significant decrease in length of median patient stay in hospital without a significant increase in associated morbidity and mortality.

Cost-effectiveness of the implementation of an enhanced recovery protocol for colorectal surgery

BACKGROUND

Enhanced recovery protocols may reduce postoperative complications and length of hospital stay. However, the implementation of these protocols requires time and financial investment. This study evaluated the cost-effectiveness of enhanced recovery implementation.

METHODS

The first 50 consecutive patients treated during implementation of an enhanced recovery programme were compared with 50 consecutive patients treated in the year before its introduction. The enhanced recovery protocol principally implemented preoperative counselling, reduced preoperative fasting, preoperative carbohydrate loading, avoidance of premedication, optimized fluid balance, standardized postoperative analgesia, use of a no-drain policy, as well as early nutrition and mobilization. Length of stay, readmissions and complications within 30 days were compared. A cost-minimization analysis was performed.

RESULTS

Hospital stay was significantly shorter in the enhanced recovery group: median 7 (interquartile range 5-12) versus 10 (7-18) days (P = 0·003); two patients were readmitted in each group. The rate of severe complications was lower in the enhanced recovery group (12 versus 20 per cent), but there was no difference in overall morbidity. The mean saving per patient in the enhanced recovery group was €1651.

CONCLUSION

Enhanced recovery is cost-effective, with savings evident even in the initial implementation period.

Adherence to Enhanced Recovery After Surgery and length of stay after colonic resection

AIM

The Enhanced Recovery After Surgery (ERAS) programme is a multimodal approach to improve peri-operative care in colon surgery. The aim of this study was to report on the adherence to and outcomes of ERAS in the first years after implementation.

METHOD

Data of patients undergoing elective colon resections for malignancy in 2006 until 2010 were compared with patients receiving conventional care in 2005. Retrospective analysis was performed including length of stay (LOS), protocol adherence and complications. The predictive values of ERAS items and baseline characteristics on LOS and complications were analysed using univariate and multivariate analysis.

RESULTS

Length of stay (LOS) was significantly shorter in 2006 and 2007 (P ≤ 0.009 and P ≤ 0.004) but not in 2008 and 2009. The mean adherence rate to the ERAS items was 84.1% in 2006 and 2007 and 72.4% in 2008 and 2009 (P < 0.001). In 2005, 2008 and 2009 LOS was significantly shorter for laparoscopically operated patients than for patients with open resections (P < 0.002, P < 0.001 and P < 0.004 respectively). Multivariate analysis showed that age, laparoscopic surgery, removal of nasogastric tube before extubation, mobilization within 24 h after surgery, starting nonsteroidal anti-inflammatory drugs at day 1 and removal of thoracic epidural analgesia at day 2 were independent predictors of LOS.

CONCLUSION

Strict adherence to the ERAS protocol was associated with reduced LOS and improved outcome in elective colon surgery for malignancy. These benefits were lost when protocol adherence was lower. Embedding the ERAS protocol into an organization and repetitive education are vital to sustain its beneficial effects on LOS and outcome.

Improving hip fracture care: striving for excellence

Hip fracture is a common and potentially devastating injury that occurs mainly in older people. The incidence is predicted to rise by 30% in the next 10 years alone. Many of those who recover suffer a loss of mobility and independence. There is growing emphasis to improve the care of patients sustaining hip fracture, especially in those with concurrent cognitive impairment. This review focuses on current best practice as well as several key areas of management, including analgesia, anaemia and nutrition. In doing so, we hope to identify interventions that may form the basis of a future Enhanced Recovery Pathway dedicated to hip fracture care.

Fast-track surgery could improve postoperative recovery in radical total gastrectomy patients

AIM: To assess the impact of fast-track surgery (FTS) on hospital stay, cost of hospitalization and complications after radical total gastrectomy.

METHODS: A randomized, controlled clinical trial was conducted from November 2011 to August 2012 in the Department of Digestive Surgery, Xijing Hospital of Digestive Diseases, the Fourth Military Medical University. A total of 122 gastric cancer patients who met the selection criteria were randomized into FTS and conventional care groups on the first day of hospitalization. All patients received elective standard D2 total gastrectomy. Clinical outcomes, including duration of flatus and defecation, white blood cell count, postoperative pain, duration of postoperative stay, cost of hospitalization and complications were recorded and evaluated. Two specially trained doctors who were blinded to the treatment were in charge of evaluating postoperative outcomes, discharge and follow-up.

RESULTS: A total of 119 patients finished the study, including 60 patients in the conventional care group and 59 patients in the FTS group. Two patients were excluded from the FTS group due to withdrawal of consent. One patient was excluded from the conventional care group because of a non-resectable tumor. Compared with the conventional group, FTS shortened the duration of flatus (79.03 ± 20.26 h vs 60.97 ± 24.40 h, P = 0.000) and duration of defecation (93.03 ± 27.95 h vs 68.00 ± 25.42 h, P = 0.000), accelerated the decrease in white blood cell count [P < 0.05 on postoperative day (POD) 3 and 4], alleviated pain in patients after surgery (P < 0.05 on POD 1, 2 and 3), reduced complications (P < 0.05), shortened the duration of postoperative stay (7.10 ± 2.13 d vs 5.68 ± 1.22 d, P = 0.000), reduced the cost of hospitalization (43783.25 ± 8102.36 RMB vs 39597.62 ± 7529.98 RMB, P = 0.005), and promoted recovery of patients.

CONCLUSION: FTS could be safely applied in radical total gastrectomy to accelerate clinical recovery of gastric cancer patients.

Increased risk for complications after colorectal surgery with selective cyclo-oxygenase 2 inhibitor etoricoxib

BACKGROUND

Cyclo-oxygenase 2 inhibitors can be used for pain treatment after colorectal surgery.

OBJECTIVE

The aim of this study was to investigate whether the use of etoricoxib has negative effects on the perioperative outcome in colorectal surgery.

DESIGN

Complication data from an advanced medical database system were sampled prospectively, and patient records were reviewed retrospectively.

PATIENTS

All patients with elective colorectal surgery within an enhanced recovery after surgery protocol from 2008 to 2009 were selected.

INTERVENTION

The nonrandomized use of perioperative etoricoxib treatment was compared with a control group.

MAIN OUTCOME MEASURES

The primary outcome measured was the number of patients with postoperative complications according to the Dindo-Clavien classification.

RESULTS

One hundred one patients received etoricoxib treatment, whereas 104 did not. The patient groups were very comparable. We observed a significant increase in the number of patients with postoperative complications with etoricoxib treatment (43 vs 30 patients; 42.6% vs 28.8%, p = 0.041) due to an increase in patients with a major complication (Dindo-Clavien complication grade III-V: 22.8% vs 9.6%, p = 0.01). Patients with etoricoxib treatment and a complication needed a longer recovery period than patients with a complication in the control group (18 (17; 20) vs 14 (13; 15) days, p = 0.05). We observed an increased level of postoperative serum creatinine with etoricoxib treatment (105 (98; 112) vs 82 (78; 85), p = 0.003), which was more pronounced in patients with a complication (141 (127; 155) vs 91 (83; 98), p = 0.002; 25 vs 8 patients with serum creatinine >100 μmol/L, p = 0.008). In multivariate analysis, etoricoxib was identified as an independent risk factor for experiencing a major complication with a risk increase of approximately 2.5-fold (p = 0.03).

LIMITATIONS

This study was limited by the nonrandomized use of perioperative etoricoxib and the retrospective nature of its review of patient records.

CONCLUSIONS

Etoricoxib increased the number of patients with postoperative complications and should be considered carefully in colorectal surgery.

A randomized placebo controlled trial of preoperative carbohydrate drinks and early postoperative nutritional supplement drinks in colorectal surgery

AIM

There is evidence that preoperative carbohydrate drinks and postoperative nutritional supplements improve the outcome of colorectal surgery. There is little information on their individual contribution.

METHOD

A prospective four-arm double-blind controlled trial was carried out in which patients were randomized to carbohydrate or placebo drinks preoperatively and a polymeric supplement or placebo drink postoperatively. The primary outcome was insulin resistance (using the short insulin tolerance test and HOMA-IR). Secondary outcomes included handgrip strength, pulmonary function, intestinal permeability and postoperative complications.

RESULTS

A total of 120 patients were randomized to four demographically well matched groups. Patients who received preoperative and postoperative supplements had better glucose homeostasis (P = 0.004), peak expiratory flow rate (P = 0.035), handgrip strength (P = 0.002) and less insulin resistance (P = 0.001) compared with those who only received placebo drinks.

CONCLUSION

Oral nutritional supplements given preoperatively and postoperatively improve postoperative handgrip strength, pulmonary function and insulin resistance. A weaker effect was seen in patients who received supplements either preoperatively or postoperatively. Oral nutritional supplements should be given both preoperatively and postoperatively.

Randomized clinical trial on enhanced recovery versus standard care following open liver resection

BACKGROUND

Enhanced recovery programmes (ERPs) have been shown to reduce length of hospital stay (LOS) and complications in colorectal surgery. Whether ERPs have the same benefits in open liver resection surgery is unclear, and randomized clinical trials are lacking.

METHODS

Consecutive patients scheduled for open liver resection were randomized to an ERP group or standard care. Primary endpoints were time until medically fit for discharge (MFD) and LOS. Secondary endpoints were postoperative morbidity, pain scores, readmission rate, mortality, quality of life (QoL) and patient satisfaction. ERP elements included greater preoperative education, preoperative oral carbohydrate loading, postoperative goal-directed fluid therapy, early mobilization and physiotherapy. Both groups received standardized anaesthesia with epidural analgesia.

RESULTS

The analysis included 46 patients in the ERP group and 45 in the standard care group. Median MFD time was reduced in the ERP group (3 days versus 6 days with standard care; P < 0·001), as was LOS (4 days versus 7 days; P < 0·001). The ERP significantly reduced the rate of medical complications (7 versus 27 per cent; P = 0·020), but not surgical complications (15 versus 11 per cent; P = 0·612), readmissions (4 versus 0 per cent; P = 0·153) or mortality (both 2 per cent; P = 0·987). QoL over 28 days was significantly better in the ERP group (P = 0·002). There was no difference in patient satisfaction.

CONCLUSION

ERPs for open liver resection surgery are safe and effective. Patients treated in the ERP recovered faster, were discharged sooner, and had fewer medical-related complications and improved QoL.

Enhanced recovery after surgery programs versus traditional care for colorectal surgery: a meta-analysis of randomized controlled trials

BACKGROUND

Enhanced recovery after surgery programs in colorectal surgery aim to attenuate the surgical stress response, reduce complications and shorten hospital stay.

OBJECTIVE

This study aimed to assess the safety and efficacy of enhanced recovery after surgery programs in colorectal surgery in comparison with traditional care.

DATA SOURCES

PubMed, Embase, and Cochrane databases were electronically searched (date range, January 1966 to July 2012).

STUDY SELECTION

Randomized controlled trials were selected that compared enhanced recovery after surgery programs with traditional care in elective colorectal surgery.

INTERVENTION

Articles were reviewed independently by 2 reviewers, who extracted the data and assessed the quality of the included studies. The outcome measures were analyzed, and the quality of evidence for each outcome was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation system.

MAIN OUTCOME MEASURES

The primary outcome measures were primary and total postoperative hospital stay, readmission rates, total postoperative complications (including general and surgical complications), and mortality.

RESULTS

Thirteen studies (total, 1910 patients) were included in the meta-analysis. In comparison with traditional care, enhanced recovery after surgery programs were associated with significantly decreased primary hospital stay (weighted mean difference, -2.44 days; 95% CI, -3.06 to -1.83 days; p < 0.00001), total hospital stay (weighted mean difference, -2.39 days; 95% CI, -3.70 to -1.09 days; p = 0.0003), total complications (relative risk, 0.71; 95% CI, 0.58-0.86; p = 0.0006), and general complications (relative risk, 0.68; 95% CI, 0.56-0.82; p < 0.0001). No significant differences were found for readmission rates, surgical complications, and mortality.

LIMITATIONS

This study was limited by the risk of bias in most included studies.

CONCLUSIONS

Enhanced recovery after surgery programs are safe and effective, and increased implementation is justified for perioperative care in colorectal surgery. Future studies may examine the benefits of enhanced recovery after surgery programs in elderly patients and in other GI surgery.

The effects of inpatient exercise therapy on the length of hospital stay in stages I-III colon cancer patients: randomized controlled trial

PURPOSE

This study aimed to examine the effects of a postsurgical, inpatient exercise program on postoperative recovery in operable colon cancer patients

METHODS

We conducted the randomized controlled trial with two arms: postoperative exercise vs. usual care. Patients with stages I-III colon cancer who underwent colectomy between January and December 2011 from the Colorectal Cancer Clinic, were recruited for the study. Subjects in the intervention group participated in the postoperative inpatient exercise program consisted of twice daily exercise, including stretching, core, balance, and low-intensity resistance exercises. The usual care group was not prescribed a structured exercise program. The primary endpoint was the length of hospital stay. Secondary endpoints were time to flatus, time to first liquid diet, anthropometric measurements, and physical function measurements.

RESULTS

A total of 31 (86.1 %) patients completed the trial, with adherence to exercise interventions at 84.5 %. The mean length of hospital stay was 7.82 ± 1.07 days in the exercise group compared with 9.86 ± 2.66 days in usual care (mean difference, 2.03 days; 95 % confidence interval (CI), -3.47 to -0.60 days; p = 0.005) in per-protocol analysis. The mean time to flatus was 52.18 ± 21.55 h in the exercise group compared with 71.86 ± 29.2 h in the usual care group (mean difference, 19.69 h; 95 % CI, -38.33 to -1.04 h; p = 0.036).

CONCLUSIONS

Low-to-moderate-intensity postsurgical exercise reduces length of hospital stay and improves bowel motility after colectomy procedure in patients with stages I-III colon cancer.

Enhanced recovery after surgery (ERAS) strategies: possible advantages also for head and neck surgery patients?

Enhanced recovery after surgery (ERAS) programs have recently been developed in order to reduce morbidity, improve recovery, and shorten hospital stays of surgical patients. Since the 1990 s, ERAS programs have been successfully applied in many centres, especially in northern Europe and America, to perioperative management for colorectal surgery, vascular surgery, thoracic surgery, and then also to urological and gynaecologic surgery. Purpose of this paper is to evaluate and discuss the very recent introduction of ERAS programs also in head and neck surgery. Embase and Pubmed database searches were performed for relevant published studies. There are still no reports concerning the results of the application of ERAS protocols in the head and neck field. ERAS programs, however, could offer also to head and neck surgery patients an advantage in terms of fastening recovery, reducing hospital stay, and favouring early return to daily activities after hospital discharge. Therefore, the investigation of specific ERAS protocol in head and neck surgery patients should be encouraged.

Intrathecal analgesia and restrictive perioperative fluid management within enhanced recovery pathway: hemodynamic implications

BACKGROUND

Intrathecal analgesia and avoidance of perioperative fluid overload are key items within enhanced recovery pathways. Potential side effects include hypotension and renal dysfunction.

STUDY DESIGN

From January 2010 until May 2010, all patients undergoing colorectal surgery within enhanced recovery pathways were included in this retrospective cohort study and were analyzed by intrathecal analgesia (IT) vs none (noIT). Primary outcomes measures were systolic and diastolic blood pressure, mean arterial pressure, and heart rate for 48 hours after surgery. Renal function was assessed by urine output and creatinine values.

RESULTS

One hundred and sixty-three consecutive colorectal patients (127 IT and 36 noIT) were included in the analysis. Both patient groups showed low blood pressure values within the first 4 to 12 hours and a steady increase thereafter before return to baseline values after about 24 hours. Systolic and diastolic blood pressure and mean arterial pressure were significantly lower until 16 hours after surgery in patients having IT compared with the noIT group. Low urine output (<0.5 mL/kg/h) was reported in 11% vs 29% (IT vs noIT; p = 0.010) intraoperatively, 20% vs 11% (p = 0.387), 33% vs 22% (p = 0.304), and 31% vs 21% (p = 0.478) for postanesthesia care unit and postoperative days 1 and 2, respectively. Only 3 of 127 (2.4%) IT and 1 of 36 (2.8%) noIT patients had a transitory creatinine increase >50%; no patients required dialysis.

CONCLUSIONS

Postoperative hypotension affects approximately 10% of patients within an enhanced recovery pathway and is slightly more pronounced in patients with IT. Hemodynamic depression persists for <20 hours after surgery; it has no measurable negative impact and therefore cannot justify detrimental postoperative fluid overload.

Effects of introducing an enhanced recovery after surgery programme for patients undergoing open hepatic resection

OBJECTIVES

Enhanced recovery after surgery (ERAS) protocols are coming to represent the standard of care in many surgical procedures, yet data on their use following hepatic surgery are scarce. The aim of this study was to review outcomes after the introduction of an ERAS programme for patients undergoing open hepatic resection.

METHODS

A retrospective review of patients undergoing open hepatic resection from March 2005 to June 2011 was carried out. The primary outcome measure was total hospital length of stay (LoS) (including readmissions). Principles associated with enhanced recovery after surgery were documented and analysed as independent predictors of hospital LoS.

RESULTS

A total of 120 patients underwent 128 consecutive hepatic resections, 84 (65.6%) of which were performed in patients with underlying colorectal metastases and 64 (50.0%) of which comprised major hepatic resections. The median hospital LoS was reduced from 6 days to 3 days from the first to the fourth quartiles of the study population (P = 0.021). The proportion of patients suffering complications (26.6%) remained constant across the series. Readmissions increased from the first quartile (none of 32 patients) to the fourth quartile (seven of 32 patients) (P = 0.044). Following multivariate analysis, only the development of a complication (P < 0.001), total postoperative i.v. fluid (P = 0.003) and formation of an anastomosis (P = 0.006) were independent predictors of hospital LoS.

CONCLUSIONS

An ERAS programme can be successfully applied to patients undergoing open hepatic resection with a reduction in hospital LoS, but an increase in the rate of readmissions.

A systematic review of outcomes in patients undergoing liver surgery in an enhanced recovery after surgery pathways

OBJECTIVES

Enhanced recovery after surgery (ERAS) or fast-track protocols have been implemented in different fields of surgery to attenuate the surgical stress response and accelerate recovery. The objective of this study was to systematically review the literature on outcomes of ERAS protocols applied in liver surgery.

METHODS

The MEDLINE, EMBASE, PubMed and Cochrane Library databases were searched for randomized controlled trials (RCTs), case-control studies and case series published between January 1966 and October 2011 comparing adult patients undergoing elective liver surgery in an ERAS programme with those treated in a conventional manner. The primary outcome measure was hospital length of stay (LoS). Secondary outcome measures were time to functional recovery, and complication, readmission and mortality rates.

RESULTS

A total of 307 articles were found, six of which were included in the review. These comprised two RCTs, three case-control studies and one retrospective case series. Median LoS ranged from 4 days in an ERAS group to 11 days in a control group. Morbidity, mortality and readmission rates did not differ significantly between the groups. Only two studies assessed time to functional recovery. Functional recovery in these studies was reached 2 days before discharge.

CONCLUSIONS

This systematic review suggests that ERAS protocols can be successfully implemented in liver surgery. Length of stay is reduced without compromising morbidity, mortality or readmission rates.

Randomized clinical trial of enhanced recovery versus standard care after laparoscopic sleeve gastrectomy

BACKGROUND

Optimized perioperative care within an enhanced recovery after surgery (ERAS) protocol is designed to reduce morbidity after surgery, resulting in a shorter hospital stay. The present study evaluated this approach in the context of sleeve gastrectomy for patients with morbid obesity.

METHODS

Patients were allocated to perioperative care according to a bariatric ERAS protocol or a control group that received standard care. These groups were also compared with a historical group of patients who underwent laparoscopic sleeve gastrectomy at the same institution between 2006 and 2010, selected using matched propensity scores. The primary outcome was median length of hospital stay. Secondary outcomes included readmission rates, postoperative morbidity, postoperative fatigue and mean cost per patient.

RESULTS

Of 116 patients included in the analysis, 78 were allocated to the ERAS (40) or control (38) group and there were 38 in the historical group. There were no differences in baseline characteristics between groups. Median hospital stay was significantly shorter in the ERAS group (1 day) than in the control (2 days; P < 0·001) and historical (3 days; P < 0·001) groups. It was also shorter in the control group than in the historical group (P = 0·010). There was no difference in readmission rates, postoperative complications or postoperative fatigue. The mean cost per patient was significantly higher in the historical group than in the ERAS (P = 0·010) and control (P = 0·018) groups.

CONCLUSION

The ERAS protocol in the setting of bariatric surgery shortened hospital stay and was cost-effective. There was no increase in perioperative morbidity.

Fast-track surgery in gynaecology and gynaecologic oncology: a review of a rolling clinical audit

Clinical audit is the process by which clinicians are able to demonstrate to themselves, their patients, hospital administrators, and healthcare financial providers the outcome and safety of their clinical practice. It is a process by which the public can be assured of safety and outcomes. A fast-track surgery program was initiated in January 2008, and this paper represents a rolling clinical audit of the outcomes of that program until the end of June 2012. Three hundred and eighty-nine patients underwent fast track surgical management after having a laparotomy for suspected or confirmed gynaecological cancer. There were no exclusions and the data presented represents the practice and outcomes of all patients referred to a single gynaecological oncologist. The majority of patients were deemed to have complex surgical procedures performed usually through a vertical midline incision. One third of patients had a nonzero performance status, median weight was 68 kilograms, and median BMI was 26.5 with 31% being classified as obese. Median operating time was 2.25 hours, and the median estimated blood loss was 175 mL. Overall the median length of stay (LOS) was 3 days with 95% of patients tolerating early oral feeding. Four percent of patients required readmission, and 0.5% were required to return to the operating room. Whilst the wound infection rate was 2.6%, there were no ureteric, bowel or neurovascular injuries. Overall there were 2 bladder injuries (0.5%), and the incidence of venous thromboembolism was 1%. Subset analysis was also undertaken. Whilst a number of variables were associated with reduced LOS, on multivariate analysis, benign pathology, shorter operating time, and the ability to tolerate early oral feeding were found to be significant. The data and experience presented is the largest and most extensive reported in the literature relating to fast-track surgery in gynaecology and gynaecologic oncology. The public can be reassured of the safety and improved outcomes that can be achieved after the introduction of such a program.

The enhanced recovery after surgery (ERAS) pathway for patients undergoing colorectal surgery: an update of meta-analysis of randomized controlled trials

OBJECTIVE

This study aimed to produce a comprehensive, up-to-date meta-analysis exploring the safety and efficacy of enhanced recovery programs after colorectal resection.

METHOD

Medline, Embase, and Cochrane database searches were performed for relevant studies published between January 1966 and April 2012. All randomized controlled trials on fast track (FT) colorectal surgery were reviewed systematically. The main end points were short-term morbidity, length of primary postoperative hospital stay, length of total postoperative stay, readmission rate, and mortality.

RESULTS

Seven randomized controlled trials with 852 patients were included. The total length of hospital stay [mean difference (95 % confidence interval), -1.88 (-2.91, -0.86), p = 0.0003] and total complication rates [relative risk (95 % confidence interval), 0.69 (0.51, 0.93), p = 0.01] were significantly reduced in the enhanced recovery group. There was no statistically significant difference in readmission (risk ratio (RR) 0.90; 95 % confidence interval (CI) 0.52 to 1.53, p = 0.69) and mortality rates (RR 1.02; 95 % CI 0.40 to 2.57, p = 0.97).

CONCLUSION

Results suggested that enhanced recovery after surgery pathways can be able to reduce the length of stay and complication rates after major colorectal surgery without compromising patient safety. Future studies have to define the active elements in order to improve future fast track protocols.

Fast-track surgery improves postoperative clinical recovery and immunity after elective surgery for colorectal carcinoma: randomized controlled clinical trial

Background

Few clinical studies or randomized clinical trial results have reported the impact of fast-track surgery on human immunity. This study aimed to investigate the clinical and immune impact of fast-track surgery in colorectal cancer patients undergoing elective open surgery.

Methods

A controlled randomized clinical trial was conducted from November 2008 to January 2009 with a 1-month postdischarge follow-up. A total of 70 patients with colorectal carcinoma requiring colorectal resection were randomized into two groups: a fast-track group (35 cases) and a conventional care group (35 cases). All included patients underwent elective open colorectal resection with combined tracheal intubation and general anesthesia. Clinical parameters and markers of immune function were evaluated in both groups postoperatively.

Results

In all, 62 patients completed the study: 32 in the fast-track group and 30 in the conventional care group. Our findings revealed a significantly shorter postoperative hospital stay and faster return of gastrointestinal function in patients undergoing fast-track rehabilitation. In addition, we found a quicker response of white blood cells in the fast-track group than in the conventional care group. We also found that blood levels of globulin, immunoglobulin G, and complement 4 on postoperative day 3 were higher in the fast-track group than in the conventional care group.

Conclusions

Fast-track surgery accelerates clinical recovery and improves postoperative immunity after elective open surgery for colorectal carcinoma.

Effects of preoperative oral carbohydrate supplementation on postoperative metabolic stress response of patients undergoing elective abdominal surgery

BACKGROUND

The goal of the present study was to evaluate the effects of preoperative oral carbohydrate supplementation (OCH) on the postoperative metabolic stress response of patients undergoing elective abdominal surgery.

METHODS

The study was designed as a controlled, prospective, cohort study including 38 patients treated with OCH (800 mL the day before surgery and 400 mL within 3 h before the induction of anesthesia) and 38 controls matched for surgical procedure. Fasting glucose, insulin, insulin resistance (HOMA-IR index), cortisol, and interleukin 6 (IL-6) were assessed before and after surgery (postoperative day (POD) 1, 2, and 3).

RESULTS

The administration of OCH resulted in lower fasting glucose, HOMA-IR index, cortisol, and IL-6 on both POD 1 and POD 2. At multivariable regression analyses, the reduction of these parameters was independent of sex, age, body mass index, and major abdominal surgery. Particularly, models including OCH treatment explained 70, 63, and 66 % of the variance of the increase in IL-6 levels at POD 1, POD 2, and POD 3, respectively. The effect of OCH on changes in glucose, insulin resistance, and cortisol on POD 1 and POD 2 disappeared after the inclusion of IL-6 in the models.

CONCLUSIONS

Treatment with OCH was associated with attenuation of the postoperative metabolic stress response. We hypothesize that modulation of the inflammatory response is one of the mechanisms involved.

Patient optimization for gastrointestinal cancer surgery

BACKGROUND

Although surgical resection remains the central element in curative treatment of gastrointestinal cancer, increasing emphasis and resource has been focused on neoadjuvant or adjuvant therapy. Developments in these modalities have improved outcomes, but far less attention has been paid to improving oncological outcomes through optimization of perioperative care.

METHODS

A narrative review is presented based on available and updated literature in English and the authors' experience with enhanced recovery research.

RESULTS

A range of perioperative factors (such as lifestyle, co-morbidity, anaemia, sarcopenia, medications, regional analgesia and minimal access surgery) are modifiable, and can be optimized to reduce short- and long-term morbidity and mortality, improve functional capacity and quality of life, and possibly improve oncological outcome. The effect on cancer-free and overall survival may be of equal magnitude to that achieved by many adjuvant oncological regimens. Modulation of core factors, such as nutritional status, systemic inflammation, and surgical and disease-mediated stress, probably influences the host's immune surveillance and defence status both directly and through reduced postoperative morbidity.

CONCLUSION

A wider view on long-term effects of expanded or targeted enhanced recovery protocols is warranted.

Evaluation of a fast-track programme for patients undergoing liver resection

BACKGROUND

Recent developments in perioperative pathophysiology and care have documented evidence-based, multimodal rehabilitation (fast-track) to hasten recovery and to decrease morbidity and hospital stay for several major surgical procedures. The aim of this study was to investigate the effect of introducing fast-track principles for perioperative care in unselected patients undergoing open or laparoscopic liver resection.

METHODS

This was a prospective study involving the first 100 consecutive patients who followed fast-track principles for liver resection. Catheters and drains were systematically removed early, and patients were mobilized and started eating and drinking from the day of surgery. An opioid-sparing multimodal pain treatment was given for the first week. Discharge criteria were: pain sufficiently controlled by oral analgesics alone, patient comfortable with discharge and no untreated complications.

RESULTS

Median length of stay (LOS) for all patients was 5 days, with 2 days after laparoscopic versus 5 days following open resection (P < 0·001). Median LOS after minor open resections (fewer than 3 segments) was 5 days versus 6 days for major resections (3 or more segments) (P < 0·001). Simple right or left hemihepatectomies had a median LOS of 5 days. The readmission rate was 6·0 per cent and 30-day mortality was zero.

CONCLUSION

Fast-track principles for perioperative care were introduced successfully and are safe after liver resection. Routine discharge 2 days after laparoscopic resection and 4-5 days after open liver resection may be feasible.

Enhanced recovery pathways as a way to reduce surgical morbidity

PURPOSE OF REVIEW

The aim of this review is to summarize important publications in enhanced recovery during 2010-2011 and to highlight key themes. Specifically, we focus on updated systematic reviews of high-quality clinical trials of enhanced recovery in colorectal surgery, exemplar studies of enhanced recovery in other specialties, and exploration of which elements of the enhanced recovery package might be associated with improved patient outcome.

RECENT FINDINGS

An expanding evidence base of clinical trials and implementation evaluations supports the effectiveness of enhanced recovery programmes in improving outcome following major elective surgery. The majority of this literature derives from the study of patients undergoing colorectal surgery, but increasingly enhanced recovery is spreading to other surgical specialties. The combination of reduced length of hospital stay (a surrogate for morbidity) with no increase in readmissions to hospital suggests that morbidity is reduced with enhanced recovery. Inconsistency in morbidity reporting limits the value of pooling data between studies, but within study comparisons in general support this conclusion. Patients adhering to an enhanced recovery programme return to normal function faster than those following traditional care pathways.

SUMMARY

Enhanced recovery adoption is likely to continue to grow (range of specialties and penetration within specialties). This progression is supported by the available published data.

Implementation of an enhanced recovery programme following pancreaticoduodenectomy

OBJECTIVES

The aim of this prospective study was to investigate the implementation of an enhanced recovery after surgery (ERAS) programme following pancreaticoduodenectomy (PD).

METHODS

Patients undergoing PD were managed according to an ERAS protocol. Outcome measures included postoperative mortality, morbidity, hospitalization and 30-day readmission rate. Key protocol targets were: nasogastric tube (NGT) removal [postoperative day (PoD) 1]; resumption of oral fluids (PoD 1); urinary catheter removal (PoD 3); high-dependency unit (HDU) discharge (PoD 3); tolerating diet (PoD 4); drain removal (PoD 5), and hospital discharge (PoD 6).

RESULTS

Data were collected for 50 patients (24 male; median age 67 years). Rates of mortality, morbidity and readmission were 4%, 46% and 4%, respectively. The median length of postoperative hospitalization was 10 days. The proportions of patients achieving key targets were: 78% for NGT removal; 82% for resumption of oral fluids; 48% for urinary catheter removal; 82% for HDU discharge; 86% for tolerating diet; 84% for meeting mobility targets, and 72% for drain removal. One patient was discharged by PoD 6, eight patients by PoD 7, 15 patients by PoD 8 and 26 patients (52%) by PoD 10. Discharge was delayed in 16 patients for social or transport-related reasons.

CONCLUSIONS

The ERAS protocol was implemented safely. Achieving certain targets was challenging. Non-medical causes remain a significant factor in delayed discharge following PD.

Guidelines for perioperative care in elective colonic surgery: Enhanced Recovery After Surgery (ERAS®) Society recommendations

BACKGROUND

This review aims to present a consensus for optimal perioperative care in colonic surgery and to provide graded recommendations for items for an evidenced-based enhanced perioperative protocol.

METHODS

Studies were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group.

RESULTS

For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (quality of evidence and recommendations according to the GRADE system).

CONCLUSIONS

Based on the evidence available for each item of the multimodal perioperative-care pathway, the Enhanced Recovery After Surgery (ERAS) Society, International Association for Surgical Metabolism and Nutrition (IASMEN) and European Society for Clinical Nutrition and Metabolism (ESPEN) present a comprehensive evidence-based consensus review of perioperative care for colonic surgery.

Fascia iliaca compartment block reduces morphine requirement pre-operatively for patients with fractured neck of femur

INTRODUCTION

Fascia iliaca compartment block, performed in the emergency department (A&E) in patients presenting with femoral neck fracture, has gained increasing recognition as an adjunctive analgesic. The purpose of this study was to investigate whether fascia iliaca block (FIB) significantly reduced the requirement for systemic opiates in the pre-operative setting.

MATERIALS AND METHODS

Analgesia requirements for all patients admitted with fractured neck of femur to one unit over a 9-month period were gathered prospectively. Fifty percent of patients had received FIB at diagnosis in the A&E, dependant on the expertise of the attending physician. Morphine administration between groups was analysed.

RESULTS

Over a 9-month period, 286 patients with complete documentation were admitted with fractured neck of femur. At the start of the study, an informal education programme in A&E was introduced, increasing the incidence of FIB provision at diagnosis (p = <0.0001, Fisher's exact test) and reducing the average amount of morphine administered (p = 0.027, linear regression analysis). The administration of FIB reduced the average morphine requirement for a patient in A&E by 41 % when compared with those who received systemic analgesia alone (p = 0.018, Mann-Whitney test). No adverse effects were reported with FIB.

CONCLUSION

Fascia iliaca compartment block is a safe and effective method of providing analgesia to patients with fractured neck of femur and reduces morphine requirement.

BACKGROUND

This review aims to present a consensus for optimal perioperative care in rectal/pelvic surgery, and to provide graded recommendations for items for an evidenced-based enhanced recovery protocol.

METHODS

Studies were selected with particular attention paid to meta-analyses, randomized controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group.

RESULTS

For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (evidence grade: high or moderate).

CONCLUSIONS

Based on the evidence available for each item of the multimodal perioperative care pathway, the Enhanced Recovery After Surgery (ERAS) Society, European Society for Clinical Nutrition and Metabolism (ESPEN) and International Association for Surgical Metabolism and Nutrition (IASMEN) present a comprehensive evidence-based consensus review of perioperative care for rectal surgery.

Enhanced recovery after surgery protocols - compliance and variations in practice during routine colorectal surgery

AIM

Although there are numerous studies on the efficacy of enhanced recovery after surgery (ERAS) protocols in reducing length of stay, the long-term compliance to such protocols in routine clinical practice has not been well documented. The aim of this study was to review the published literature on compliance to ERAS in patients undergoing colorectal surgery in routine clinical practice.

METHOD

Medline, Embase and PubMed databases were searched to identify studies that focused on compliance to ERAS protocols during routine clinical practice. Fourteen studies fulfilled the inclusion criteria and a total of 19 perioperative ERAS modalities were identified across these studies.

RESULTS

None of the studies used all 19 ERAS modalities within their ERAS protocols. Compliance to the various modalities varied considerably between studies and, in general, was poorest during the postoperative period. The use of epidural had the highest compliance (between 67 and 100%), whereas the use of transverse incisions (25%) had the lowest compliance. Length of stay in hospital ranged from 2 to 13 days. Higher compliance was associated with a reduced length of hospital stay. However, reduced length of hospital stay was associated with a high rate of readmission.

CONCLUSION

There is significant variation in the components of, as well as in compliance to, ERAS protocols in daily practice. This may contribute to the observed variation between the studies in length of hospital stay. A standardized and practically feasible ERAS protocol should be established in order to improve the implementation and optimal outcome.

Length of stay after laparoscopic colonic surgery - an 11-year nationwide Danish survey

AIM

The use of laparoscopic colonic surgery in Denmark was analysed with particular reference to the length of stay.

METHOD

Data were obtained from the Danish National Patient Registry to assess duration of hospital stay after laparoscopic colonic surgery in Denmark within the 11-year period from 2000 to 2010.

RESULTS

There were 4582 laparoscopic colonic resections performed, reaching about 1000 operations/year in the last 2 years (2009-2010). Length of stay decreased from a median of 7 to 4 days, while mean length of stay only decreased from 9 to 7 days.

CONCLUSION

The use of laparoscopic colonic resection has increased in Denmark over the last 11 years and with a concomitant decrease in postoperative length of stay. However, there is a need for further improvement by combining the laparoscopic technique with fast-track recovery.
