Application of enhanced recovery after surgery in partial nephrectomy for renal tumors: A systematic review and meta-analysis

Clinical application of 4N-enhanced recovery after surgery in retroperitoneal laparoscopic resection of adrenal tumors

Background

Enhanced recovery after surgery (ERAS) has been widely applied in various surgical fields to improve postoperative recovery and reduce complications. However, its application in retroperitoneal laparoscopic resection of adrenal tumors remains limited. This study aimed to evaluate the effect and value of the 4N-ERAS protocol, which includes no Foley catheter, no drainage, no antibiotics, and "no pain" management for the postoperative recovery of patients undergoing retroperitoneal laparoscopic adrenal tumors resection.

Methods

We retrospectively analyzed data from 85 patients with adrenal tumors who were treated in the Urology Department of The University of Hong Kong-Shenzhen Hospital from January 2019 to December 2023. Of them, 42 patients were treated with the 4N-ERAS protocol (4N-ERAS group) and 43 patients received traditional treatment (control group). We compared clinical characteristics, such as sex, age, mean body mass index (BMI), preoperative diagnosis, tumor size, tumor location, and postoperative outcomes, including time to first flatus, time to first ambulation, time to Foley catheter removal, time to retroperitoneal drainage tube removal, postoperative pain score [Numeric Rating Scale (NRS)], length of hospital stay, total hospitalization costs, and postoperative complications between the two groups.

Results

There were no significant differences in terms of clinical characteristics between the two groups. Compared to the control group, the 4N-ERAS group exhibited shorter times for first flatus, first ambulation, Foley catheter removal, retroperitoneal drainage tube removal, lower postoperative pain scores (NRS), and shorter hospital stays (P<0.05). Furthermore, compared to the control group, the total hospitalization cost was significantly lower in the 4N-ERAS group (P<0.05). There were no significant differences in terms of postoperative complications between the two groups (P=0.19).

Conclusions

The 4N-ERAS protocol for retroperitoneal laparoscopic resection of adrenal tumors may expedite postoperative recovery, reduce pain, and lower overall hospital costs. This preliminary study demonstrated the safety and feasibility of the 4N-ERAS protocol for retroperitoneal laparoscopic resection of adrenal tumors, warranting future multicenter prospective, randomized, controlled trials in this field.

Assessment of mechanical bowel preparation prior to nephrectomy in the minimally invasive surgery era: insights from a national database analysis in the United States

Purpose

This study was performed to evaluate the association between mechanical bowel preparation (MBP) and perioperative outcomes following nephrectomy in the minimally invasive surgery (MIS) era.

Methods

All partial and radical nephrectomies between 2019 and 2021 from the National Surgical Quality Improvement Program database were evaluated. Thirty-day perioperative outcomes were compared between groups where MBP was performed vs. not, in both the MIS and open surgery (OS) cohorts. A propensity score matching technique was utilized within MIS cases to control for covariates. The chi-square and t tests were used to determine significance.

Results

A total of 11,869 cases met the inclusion criteria and were included in the analysis. Of these, 8,204 (69.1%; comprising 65.3% robotic and 34.7% laparoscopic) underwent MIS, while 3,655 (30.9%) underwent OS. The rate of MBP was higher in the MIS group (16.0% vs. 10.0%, p < 0.001). Within the MIS group, MBP was associated with reduced rates of postoperative ileus (0.9% vs. 1.9%, p = 0.02), while other complications were comparable. Propensity score matching showed no association between MBP and postoperative ileus. However, a lower rate of 30-day readmission in the MBP group became statistically significant (4.4% vs. 6.4%, p = 0.01). Conversely, patients in the MBP group also demonstrated higher rates of pneumonia (1.29% vs. 0.46%, p = 0.002) and pulmonary embolism (0.6% vs. 0%, p < 0.001) after matching.

Conclusion

MBP practice prior to nephrectomy is infrequent in both OS and MIS cases, with minor differences in perioperative outcomes for patients undergoing MIS. Routine MBP should continue to be excluded from the standard of care for nephrectomy in the MIS era.

The effect of enhanced recovery after surgery (ERAS) in renal surgery

OBJECTIVE

To study the effect of ERAS on a textbook outcome (TO) after elective renal surgery.

PATIENTS AND METHODS

Retrospective study of all patients who underwent a robot-assisted laparoscopic partial or radical nephrectomy or robot-assisted laparoscopic radical nephroureterectomy in Medisch Spectrum Twente (MST), Enschede, the Netherlands. In total, 277 patients were included. 66 patients from 2018 to 2021 (pre-ERAS group) and 211 patients from 2021 to 2023 (ERAS group). TO is a maximum of two nights in the hospital after surgery, no severe complications during or after surgery ≥ grade IIIb, no blood transfusions, no intensive care, no readmissions, and no mortality within 30 days after surgery. Comparisons were made between the pre-ERAS and ERAS groups using unpaired t-test, Mann-Whitney U test, the chi-squared test or Fisher's exact test. Multivariate logistic regression was used to adjust for possible confounding.

RESULTS

TO was significantly (p = 0.005) better in the ERAS group (TO = 76.8%) compared to the pre-ERAS group (TO = 59.1%). Compared to a pre-ERAS patient, the adjusted odds ratio for achieving a TO as an ERAS patient is 2.1 (95% CI 1.15-3.78).

CONCLUSIONS

The implementation of ERAS showed a positive effect on the TO of elective renal surgery patients.

Robot-assisted partial nephrectomy in patients aged 75 years or older - comparing the risk of complications with their younger counterparts

BACKGROUND & AIM

More elderly patients are diagnosed with kidney tumors where partial nephrectomy is technically possible. We investigated whether patients ≥ 75 years old had an increased risk of complications following robot-assisted partial nephrectomy (RAPN) compared to younger patients.

METHODS

Retrospective, consecutive study including patients who underwent RAPN between May 2016 - April 2023. Preoperative data, operative data and complications within 90 days were recorded by patient record review. Complications were classified according to Clavien-Dindo (CD).

RESULTS

451 patients underwent RAPN and a postoperative complication was recorded in 131 (29%) patients of which 28 (6%) were CD ≥ III. Any postoperative complication was recorded in 24/113 patients (21%) < 55 years, 40/127 patients (31%) 55-64 years, 45/151 patients (42%) 65-74 years, and 22/60 patients (37%) ≥ 75 years. Comparable numbers for a CD ≥ III postoperative complication were 2/113 (2%) < 55 years, 6/127 (7%) 55-64 years, 12/151 (8%) 65-74 years, and 5/60 (8%) ≥ 75 years. In multivariate logistic regression analysis, patients ≥ 75 years had a non-significant increased risk of complications when controlling for preoperative variables (OR 1.82 [95% CI 0.80-4.13]) or perioperative variables (OR 1.98 [95% CI 0.86-4.58]) compared to patients < 55 years. Two patients died postoperatively. Both were ≥ 75 years (2/60, 3%).

DISCUSSION AND CONCLUSIONS

Selected patients ≥ 75 years can undergo RAPN without a significantly increased risk of postoperative complications. However, a mortality rate of 3% in this age group indicates that these patients are frail when postoperative complications occur.

The application of enhanced recovery after surgery (ERAS) in chronic rhinosinusitis patients undergoing endoscopic sinus surgery: A systematic review and meta-analysis

OBJECTIVES

Enhanced recovery after surgery (ERAS) has become extensively practiced and has shown encouraging benefits. Within recent years, ERAS has also been increasingly performed in chronic rhinosinusitis (CRS) patients undergoing endoscopic sinus surgery (ESS). However, the actual efficacy of ERAS in CRS patients undergoing ESS is not completely clear, and the related evidence remains weak. This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of ERAS in the perioperative management of CRS patients receiving ESS.

METHODS

We searched randomized controlled trials in PubMed, Web of Science, EMBASE, Cochrane CENTRAL, Ovid, China National Knowledge Infrastructure, Chinese BioMedical Literature Database, Wanfang, and VIP Database up to February 2023, to analyze the effectiveness and safety of ERAS in ESS perioperative management of CRS patients. We appraised the methodological quality in the included RCTs using the Cochrane Collaboration tool and assessed the quality of evidence with the Recommendations Assessment, Development and Evaluation (GRADE) tool. Meta-analysis, subgroup analysis, and sensitivity analysis were carried out with the the software Review Manager 5.3 and Stata 12.0. In addition, potential publication bias was detected by Begg's test, Egger's test, and funnel plot test.

RESULTS

Twenty-eight studies involving 2636 patients were included within this study. In comparison with the standard care (SC) group, the ERAS group had the advantages in the following aspects: length of stay (MD = -2.50, 95%CI: -3.04 to -1.97), pain scores (MD = -1.07, 95%CI: -1.46 to -0.67), anxiety score (SMD = -2.13, 95%CI: -2.83 to -1.44), depression score (SMD = -2.42, 95%CI: -3.13 to -1.71), hospitalization expenses, and quality of life. At the same time, the ERAS group presented a markedly lower incidence of adverse events in comparison to the SC group, such as overall complications (RR = 0.28, 95%CI:0.20 to 0.41), postoperative nausea and vomiting (RR = 0.33, 95%CI:0.21 to 0.50), facial edema (RR = 0.20, 95%CI:0.11 to 0.38), low back pain (RR = 0.28, 95%CI:0.16 to 0.49), urinary retention (RR = 0.12, 95%CI:0.05 to 0.30) and haemorrhage (RR = 0.19, 95%CI:0.07 to 0.55).

CONCLUSIONS

The results showed that the ERAS protocol is effective and safe in CRS patients who undergo ESS. However, Due to the limited overall methodological quality included studies, caution should be exercised in the interpretation of the results. More high-quality, multiple-centre, and large-sample studies are in demand in the future to further validate its clinical efficacy.

Effect of acupuncture inclusion in the enhanced recovery after surgery protocol on tumor patient gastrointestinal function: a systematic review and meta-analysis of randomized controlled studies

Introduction

Acupuncture has been shown to be effective in restoring gastrointestinal function in tumor patients receiving the enhanced recovery after surgery (ERAS) protocol. The present systematic review and meta-analysis aimed to evaluate the rationality and efficacy of integrating acupuncture in the ERAS strategy to recuperate gastrointestinal function.

Methods

We searched eleven databases for relevant randomized clinical trials (RCTs) of acupuncture for the treatment of gastrointestinal dysfunction in tumor patients treated with the ERAS protocol. The quality of each article was assessed using the Cochrane Collaboration risk of bias criteria and the modified Jadad Scale. As individual symptoms, the primary outcomes were time to postoperative oral food intake, time to first flatus, time to first distension and peristaltic sound recovery time (PSRT). Pain control, adverse events, and acupoint names reported in the included studies were also investigated.

Results

Of the 211 reviewed abstracts, 9 studies (702 patients) met eligibility criteria and were included in the present systematic review and meta‑analysis. Compared to control groups, acupuncture groups showed a significant reduction in time to postoperative oral food intake [standardized mean difference (SMD) = -0.77, 95% confidence interval (CI) -1.18 to -0.35], time to first flatus (SMD=-0.81, 95% CI -1.13 to -0.48), time to first defecation (SMD=-0.91, 95% CI -1.41 to -0.41, PSRT (SMD=-0.92, 95% CI -1.93 to 0.08), and pain intensity (SMD=-0.60, 95% CI -0.83 to -0.37).The Zusanli (ST36) and Shangjuxu (ST37) acupoints were used in eight of the nine included studies. Adverse events related to acupuncture were observed in two studies, and only one case of bruising was reported.

Discussion

The present systematic review and meta‑analysis suggested that acupuncture significantly improves recovery of gastrointestinal function and pain control in tumor patients receiving the ERAS protocol compared to the control group. Moreover, ST36 and ST37 were the most frequently used acupoints. Although the safety of acupuncture was poorly described in the included studies, the available data suggested that acupuncture is a safe treatment with only mild side effects. These findings provide evidence-based recommendations for the inclusion of acupuncture in the ERAS protocol for tumor patients.
