Comparison of early postoperative pain after partial tumour nephrectomy by flank, transabdominal or laparoscopic access

Erector spinae plane block versus quadratus lumborum block for postoperative analgesia after laparoscopic nephrectomy: A randomized controlled trial

STUDY OBJECTIVE

We compared the analgesic effects of erector spinae plane block versus quadratus lumborum block following laparoscopic nephrectomy.

DESIGN

A randomized controlled trial.

SETTING

A tertiary hospital in Beijing, China.

PATIENTS

Patients scheduled for elective laparoscopic nephrectomy.

INTERVENTIONS

A total of 110 patients were enrolled and randomized to receive either erector spinae plane block (n = 55) or quadratus lumborum block (n = 55) under ultrasound guidance. Patient-controlled sufentanil analgesia was provided after surgery.

MEASUREMENTS

Our primary outcome was cumulative opioid consumption within 24 h after surgery. Secondary outcomes included postoperative pain intensity, subjective sleep quality, and quality of recovery.

MAIN RESULTS

All 110 patients (mean 53 years, 57.3% female) were included in the intention-to-treat analysis. Cumulative sufentanil equivalent within 24 h was lower in patients given erector spinae plane block (median 13 μg, interquartile range 4 to 33) than in those given quadratus lumborum block (median 25 μg, interquartile range 13 to 39; median difference - 8 μg, 95% CI -15 to 0, P = 0.041). Pain intensity (0-10 range where 0 = no pain and 10 = the worst pain) at 2, 6, 12, and 24 h after surgery was lower with erector spinae plane block (at rest: median differences -1 point, all P ≤ 0.009; with movement: median differences -2 to -1 points, all P < 0.001). Subjective sleep quality on the night of surgery (the Richards-Campbell Sleep Questionnaire: 0-100 range, higher score better; median difference 12, 95% CI 2 to 23, P = 0.018) and quality of recovery at 24 h (the Quality of Recovery-15: 0-150 range, higher score better; median difference 8, 95% CI 2 to 15, P = 0.012) were better with erector spinae plane block. No procedure-related adverse events occurred.

CONCLUSIONS

Compared with quadratus lumborum block, erector spinae plane block provided better analgesia as manifested by lower opioid consumption and pain intensity for up to 24 h after laparoscopic nephrectomy.

Graft retrieval incisions in minimally invasive donor nephrectomy: Systematic review and network meta-analysis

BACKGROUND

Various incisions are employed for graft extraction during minimally invasive donor nephrectomy, but an overarching synthesis of associated short-term donor outcomes is lacking.

METHODS

An electronic literature search was conducted on PubMed, EMBASE and Scopus for studies comparing ≥2 graft extraction incisions in laparoscopic or robotic donor nephrectomy with ≥10 patients per arm. Eligible study designs included randomized trials, case-control, and cohort studies. Primary outcomes were donor length of stay (LOS); in-hospital analgesic requirement; and postoperative complications. Secondary outcomes were warm ischemia time (WIT), total operation time (TOT), and estimated blood loss (EBL). Random-effects Frequentist network meta-analyses were conducted for all outcomes.

RESULTS

Twenty-nine studies (4702 patients) were shortlisted. Six incisions were analyzed: iliac, Pfannenstiel, midline hand-assisted laparoscopic (HAL), midline umbilical, flank and transvaginal natural orifice transluminal endoscopic surgery (NOTES). The flank incision had significantly longer LOS than all other incisions. LOS was significantly longer in Pfannenstiel than iliac incision (mean difference [MD] = 0.29, 95%CI = 0.002-0.58 days). Midline HAL had significantly shorter TOT than most other incisions. Midline umbilical incisions had significantly higher WIT than midline HAL and Pfannenstiel incisions. Midline HAL had shorter WIT than transvaginal NOTES (MD = 0.80, 95%CI = 0.05-1.56 min). No major differences were seen in analgesia requirement, postoperative complications and EBL.

CONCLUSION

Six different incisions for graft retrieval are broadly comparable across most short-term outcomes although long-term outcomes remain to be elucidated. Iliac and Pfannenstiel incisions yielded similar outcomes besides marginally lower LOS for the former. Midline incision for HAL may be associated with shorter TOT, and transvaginal NOTES is an effective technique for selected female donors.

Efficacy Of Quadratus Lumborum Blocks (QLBs) in Robotic Nephrectomy: A Retrospective Study

INTRODUCTION

Abdominal blocks such as quadratus lumborum block (QLB) have been used as an effective analgesic in abdominal surgeries. However, their efficacy in kidney surgery remains unknown. To the best of our knowledge, there are no clinical studies exploring the relationship between QLBs and post-operative opioid consumption in robotic laparoscopic nephrectomy.

OBJECTIVES

To assess the analgesic efficacy of QLB and its impact on perioperative opioid consumption in robotic laparoscopic nephrectomy.

MATERIALS AND METHODS

A retrospective chart review was conducted by querying the electronic medical record system of a 2,200-bed tertiary academic hospital center in New York City. The primary measured outcome was postoperative morphine milligram equivalents (MME) consumption for the first 24 hours. Secondary outcomes include intra-operative MME as well as postoperative pain scores measured on a visual analogue scale (VAS) scale at 2, 6, 12, 18, and 24 hours postoperatively.

RESULTS

The mean total postoperative MME in the posterior QLB (pQLB) group was 11 in the QLB group (interquartile range (IQR) 4, 18) and 15 in the control group (IQR 5.6, 28) . There was a significant reduction in intraoperative MME in the QLB group in comparison to the control group. This reduction was not seen in postoperative MME. There was no significant difference in pain scores at any of the measured time points up to 24 hours postoperatively.

CONCLUSION

Our study provides compelling support that ultrasound guided QLB significantly decreased intraoperative opioid requirements but did not have the same effect on postoperative opioid requirements following robotic kidney surgeries in the context of an enhanced recovery after surgery (ERAS) pathway.

Effect of transversus abdominis plane block on the quality of recovery in laparoscopic nephrectomy: A prospective double-blinded randomized controlled clinical trial

BACKGROUND

Poorly controlled acute postoperative pain after laparoscopic nephrectomy may adversely affect surgical outcomes and increase morbidity rates. In addition, excessive use of opioids during surgery may slow postoperative endocrine and metabolic responses and cause opioid-related side effects and opioid-induced hyperalgesia. The purpose of this study was to evaluate the effect of ultrasound-guided transversus abdominis plane (TAP) block on the postoperative quality of recovery and intraoperative remifentanil requirement in laparoscopic nephrectomy.

METHODS

Sixty patients who underwent laparoscopic nephrectomy were randomly divided into 2 groups: TAP and Control groups. After induction of anesthesia and before awakening from anesthesia, the TAP group was administered 40 mL of 0.375% ropivacaine and the Control group was administered 40 mL of normal saline to deliver ultrasound-guided TAP block using 20 mL of each of the above drugs. The main objectives of this study were to evaluate the effect of the TAP block on quality of recovery using the Quality of Recovery 40 (QoR-40) questionnaire and assessments of intraoperative remifentanil requirement. In addition, to evaluate the postoperative analgesic effect of the TAP block, the total usage time for patient-controlled analgesia (PCA) and the number of PCA bolus buttons used in both groups were analyzed.

RESULTS

The QoR-40 score, measured when visiting the ward on the third day after surgery, was significantly higher in the TAP group (171.9 ± 23.1) than in the Control group (151.9 ± 28.1) (P = .006). The intraoperative remifentanil requirement was not significantly different between the groups (P = .439). In the TAP group, the frequency of bolus dose accumulation at 1, 2, 3, 6, 12, 24, 48, and 72 hours after surgery was low enough to show a significant difference, and the total usage time for PCA was long enough to show a significant difference.

CONCLUSION

In conclusion, we determined that ultrasound-guided TAP block during laparoscopic nephrectomy improves the quality of postoperative recovery and is effective for postoperative pain control but does not affect the amount of remifentanil required for adequate anesthesia during surgery.

Robot-assisted endoscopic inguinal lymphadenectomy: A review of current outcomes

Objective

To review the role of robot-assisted endoscopic inguinal lymphadenectomy (RAIL) in the management of penile cancer.

Methods

A PubMed search for all relevant publications regarding RAIL series up until August 2019 was performed using the keyword “robotic”, “inguinal lymph node dissection”, and “penile cancer”. Weighted mean was calculated in the largest series for all outcomes using the number of patients included in each study as the weighting factor.

Results

We identified 23 articles, of note the three largest series that included 102, 27, and 20 RAIL in 51, 14, and 10 patients, respectively. Saphenous vein was spared in 88.93% of RAIL cases in these series and node yield was 11.42 per groin; 35.28% of patients had positive pathological nodes. The weighted mean of operative time was 87.98 min per RAIL and the estimated blood loss was 37.08 mL per patient. The mean length of hospital stay was 1.29 days and the drain was kept in place for 17.02 days; the major complication rate was only 5.31% in these series. The mean follow-up was 33.46 months with a recurrence-free survival of 96.33%.

Conclusion

The literature regarding RAIL describes promising results, although it has shorter follow-up and higher costs when compared to historically series from the open approach. Initials series reported lower cutaneous complications compared to conventional approach, without compromising oncological outcomes. However, long-term results and larger trials are crucial to validate those findings.
