Enhanced Recovery After Surgery: Urology

Logistic Regression Is Non-Inferior to the Response Surface Model in Patient Response Prediction of Video-Assisted Thoracoscopic Surgery

Response surface models (RSMs) are a new trend in modern anesthesia. RSMs have demonstrated significant applicability in the field of anesthesia. However, the comparative analysis between RSMs and logistic regression (LR) in different surgeries remains relatively limited in the current literature. We hypothesized that using a total intravenous anesthesia (TIVA) technique with the response surface model (RSM) and logistic regression (LR) would predict the emergence from anesthesia in patients undergoing video-assisted thoracotomy surgery (VATS). This study aimed to prove that LR, like the RSM, can be used to improve patient safety and achieve enhanced recovery after surgery (ERAS). This was a prospective, observational study with data reanalysis. Twenty-nine patients (American Society of Anesthesiologists (ASA) class II and III) who underwent VATS for elective pulmonary or mediastinal surgery under TIVA were enrolled. We monitored the emergence from anesthesia, and the precise time point of regained response (RR) was noted. The influence of varying concentrations was examined and incorporated into both the RSM and LR. The receiver operating characteristic (ROC) curve area for Greco and LR models was 0.979 (confidence interval: 0.987 to 0.990) and 0.989 (confidence interval: 0.989 to 0.990), respectively. The two models had no significant differences in predicting the probability of regaining response. In conclusion, the LR model was effective and can be applied to patients undergoing VATS or other procedures of similar modalities. Furthermore, the RSM is significantly more sophisticated and has an accuracy similar to that of the LR model; however, the LR model is more accessible. Therefore, the LR model is a simpler tool for predicting arousal in patients undergoing VATS under TIVA with Remifentanil and Propofol.

Performing percutaneous nephrolithotomy under modified local anesthesia

Objective

This pilot study aimed to assess the practicability and effectiveness of percutaneous nephrolithotomy (PCNL) with vacuum-assisted nephrostomy sheaths for patients under modified local anesthesia (m-LA).

Methods

PCNL with a vacuum-assisted nephrostomy sheath under m-LA was performed in 83 patients between November 2020 and May 2021. An 18F or 20F ClearPetra Nephrostomy Sheath connected vacuum aspiration was used in surgery to keep low pressure in the renal pelvis. For LA, lidocaine and ropivacaine hydrochloride were 1:1 mixed and instilled under ultrasound guidance through the percutaneous nephrolithotomy channel directed toward the design calix. Demographic characteristics, stone characteristics, visual analogue scale (VAS) score, vital signs, operation time, complications, and stone clear rate were recorded and analyzed.

Results

All operations were completed. The mean VAS score was 3.9 ± 1.0. The mean operation time was 55.1 ± 23.6 min. The changes for systolic blood pressure, diastolic blood pressure, and heart rate were 3 ± 21 mmHg, 1 ± 14 mmHg, and −6 ± 14 beats/min, respectively. The change for hemoglobin was −10.7 ± 10.9 g/L. The change for C-reactive protein was 5.39 ± 43.1 mg/L. The total stone-free rate was 69.9% (93.8% for simple stones and 54.9% for complex stones).

Conclusion

Performing PCNL with vacuum-assisted nephrostomy sheaths under modified local anesthesia under ultrasound guidance was found to be strongly practical and effective.

Enhanced recovery after surgery (ERAS) protocol in spine surgery

Enhanced recovery after surgery (ERAS) protocols are a set of interventions which are carried out in the preoperative and perioperative period. They are aimed to decrease the harmful effects of surgery on the body and help the patient recover better post-surgery. The effectiveness of ERAS has been well established in various other surgical specialities. Earlier spine surgery was thought to be very complex for application of ERAS protocols. However, this has changed over the last decade with (ERAS) protocols gaining widespread popularity in spine surgery. Initial studies involving ERAS in spine surgery were limited to lumbar spine. However, over the years the horizon of ERAS has expanded to include anterior cervical surgeries, spine deformity, spinal tumors and spine surgery in the elderly. ERAS has been shown to reduce the length of hospital stay, overall hospital costs, opioid consumption in perioperative and postoperative period and to lower complication rates in spine surgery. In this narrative review, we discuss various aspects of ERAS in spine surgery including the benefits of ERAS in spine surgery, the various components of preoperative, intraoperative and postoperative measures of ERAS protocol.

An Enhanced Recovery After Surgery protocol for robotic-assisted laparoscopic nephrectomies utilizing a quadratus lumborum block

Enhanced Recovery After Surgery (ERAS) protocols have been developed in several fields to reduce hospitalization lengths and overall costs. There have also been developments in multimodal analgesia methods to curtail opioid usage after surgery. Herein, we present the results of our initiation of an ERAS protocol for robotic-assisted laparoscopic partial and radical nephrectomies, employing a quadratus lumborum (QL) regional anesthetic block. We retrospectively reviewed 614 patients in our Institutional Review Board approved database who underwent robotic-assisted laparoscopic partial or radical nephrectomies from January 2017 to February 2020. An ERAS protocol utilizing multimodal analgesia (acetaminophen and gabapentin) and a QL block was developed and introduced in February 2019. We then compared the opioid consumption and perioperative outcomes of patients before and after ERAS protocol initiation. 192 ERAS patients (February 2019 to February 2020) were compared to 422 non-ERAS patients (January 2017 to January 2019). Baseline characteristics and the proportion of preoperative opioids users were similar between the two groups. There were no statistically significant differences in surgery length, hospitalization length, or complication rates. There were statistically significant differences in our primary endpoint, opioid consumption, on post-operative days 0 (p < 0.001), 1 (p < 0.001), and 2 (p < 0.001). The total opioid requirements over the course of admission were lower in the ERAS group compared to the non-ERAS group (p = 0.03). The initiation of an ERAS protocol employing multimodal analgesia and a QL block, for patients undergoing robotic-assisted laparoscopic partial or radical nephrectomies, can decrease opioid requirements without compromising perioperative outcomes.

Concomitant robot-assisted laparoscopic surgeries for upper and lower urinary tract malignancies: a comprehensive literature review

Worldwide, we have witnessed an expansion of robot-assisted laparoscopic surgery (RALS) and thanks to the global adoption of high-resolution diagnostic imaging technologies, an increased incidence of newly diagnosed prostatic, renal and bladder cancers has been recorded with concurrent second primary urological cancer diagnoses increasing by 1.5%. Diverse authors have reported their findings concerning synchronous multi-visceral malignances robotic treatment within the scientific literature. The aim of this study is to comprehensively review all reported articles describing concurrent upper and lower RALS using a singular robotic port scheme within the same intervention for renal malignances and concomitant prostatic or bladder cancers. To the best of our knowledge and vigorous literature search, this is the first study that comprehensively evaluates and reports all combined upper and lower urinary tract surgeries published so far. In carefully selected patients, thanks to multidisciplinary preoperative assessment and surgical planning a combined robotic approach can reduce the morbidity, complications, hospital admissions and the overall length of hospitalization.

Implementation of a multimodal opioid-sparing enhanced recovery pathway for robotic-assisted radical prostatectomy

The purpose of the study is to evaluate the impact of a multimodal Enhanced Recovery After Surgery (ERAS) protocol on perioperative opioid consumption and hospital length of stay (LOS) after robotic-assisted radical prostatectomy (RARP). We compared the first 176 patients enrolled in the protocol (ERAS group) with the previous 176 patients (non-ERAS group) at a single quaternary institution from December 2017 to June 2019. The ERAS protocol included a multimodal opioid-sparing regimen utilizing acetaminophen, gabapentin, celecoxib, and liposomal bupivacaine. Demographic data, co-morbidities, post-operative pain scores, post-operative opiate consumption measured by morphine milligram equivalents (MME), operating time, and LOS were collected. The two groups were compared using chi-squared, Fisher exact, or Student t tests as appropriate. Multivariable logistic regression analysis was performed to identify predictors of prolonged LOS (> 1 day). The ERAS and non-ERAS groups were equivalent in terms of baseline characteristics and pathological data. The ERAS group had lower post-operative pain scores, post-operative opiate consumption (MME 15 vs. 46, p < 0.01), and LOS (1.2 vs. 1.7 days, p < 0.01) compared to the non-ERAS group. Only 22% in the ERAS cohort had a prolonged LOS compared to 39% of the non-ERAS group (p < 0.01). The ERAS protocol was a negative predictor of prolonged LOS on multivariable logistic regression analysis (odds ratio 0.39, 95% confidence interval 0.22-0.70, p < 0.01). A limitation of this study is its single-center retrospective design. The implementation of a multimodal opioid-sparing ERAS protocol was associated with improved pain control, reduced perioperative opioid usage, and shorter LOS after RARP.

Empowerment-Based Education in Urological Patients: A Scoping Review

Prostate, kidney, and bladder cancer are the three most frequently diagnosed urological cancers. Educational programs could teach patients to become experts in disease management. The aim of this scoping review was to explore the literature to identify the educational requirements and strategies for improving and implementing educational processes for urological patients undergoing surgery. We searched several databases, including PubMed, CINAHL, Embase, Scopus, PsycINFO, and Cochrane Library. All adult patients undergoing urological educational interventions were included in the review. Of 3,197 initially identified articles, 42 were retained. Urological patients undergoing prostatectomy, cystectomy, and nephrectomy require cognitive, psychological, and functional support. For each level of support, several methods exist to provide support, including informational brochures, preoperative counseling, telephone support, online content, educational videos, support groups, individual stress management interventions, peer support, online interventions, partner support, and various educational programs that help the patient manage negative effects associated with the urological intervention.

Long-term Success With Diminished Opioid Prescribing After Implementation of Standardized Postoperative Opioid Prescribing Guidelines: An Interrupted Time Series Analysis

OBJECTIVE

To assess longitudinal prescribing patterns for patients undergoing urologic surgery in the nearly 2-year time frame before and after implementation of an evidence-based opioid prescribing guideline to accurately characterize the impact on postoperative departmental practices.

PATIENTS AND METHODS

Historical prescribing data for adults who underwent 21 urologic procedures at 3 academic institutions were used to derive a 4-tiered guideline for postoperative opioid prescribing. The guideline was implemented on January 16, 2018, and prescribing patterns including quantity of opioids prescribed (in oral morphine equivalents [OMEs]) and refill rates were compared for opioid-naïve patients undergoing urologic surgery before (January 1, 2016, through January 15, 2018; N=10,649) and after (January 16, 2018, through September 30, 2019; N=9422) guideline implementation. Univariate analysis was performed using Wilcoxon rank sum and χ² tests. Cochran-Armitage trend tests and interrupted time series analysis were used to test for significance in the change in OMEs prescribed before vs after guideline implementation.

RESULTS

The median quantity of opioids decreased from 150 OMEs (interquartile range, 0-225) before guideline implementation to 0 OMEs (interquartile range, 0-90) after guideline implementation (P<.001). Median OMEs decreased significantly in each tier and each of 21 individual procedures. Overall guideline adherence was 90.7% (n=8547). Despite this decrease in OMEs prescribed, post-guideline implementation patients obtained fewer refills than the pre-guideline implementation group (614 [6.5%] vs 999 [9.4%]; P<.001).

CONCLUSION

In a multi-institutional follow-up prospective study of adult urologic surgery-specific evidence-based guidelines for postoperative prescribing, we demonstrate sustained reduction in OMEs prescribed secondary to guideline implementation and adherence by our providers.

Implementation of a nonopioid protocol following robot-assisted radical cystectomy with intracorporeal urinary diversion

PURPOSE

The implementation of robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) for management of patients with muscle-invasive or high-risk noninvasive bladder cancer has increased in utilization over the last decade. Here, we seek to describe institutional opioid prescription and utilization patterns following implementation of a nonopioid (NOP) perioperative pain management protocol in patients who received RARC with ICUD.

MATERIALS AND METHODS

The records of all patients who underwent RARC that utilized a NOP perioperative pain management protocol at a single academic institution from 2016 to 2020 were retrospectively reviewed. Descriptive statistical analyses were performed. For comparison, we included 74 consecutive patients who received the same NOP protocol with extracorporeal urinary diversion (ECUD).

RESULTS

A total of 116 patients who received ICUD were included in our analysis. The median operation time for the ICUD group was 305 minutes (interquartile range [IQR]: 262-352). 12.1% (n = 14) of patients who underwent ICUD required narcotics during inpatient hospitalization. For these patients, the median morphine milligram equivalent requirement was 52.0 (IQR: 7.62-157). Additionally, only 12.1% (n = 14) of patients were prescribed opioids postoperatively at discharge. We identified that within 6 months of surgery only 5 (4.3%) patients required a second narcotic prescription. Furthermore, of patients who did not use mu-opioid blockers, a minority experienced postoperative ileus (15.7%, n = 16). 30- and 90-day all Clavien complication rates for patients were 44.8% (n = 52) and 49.1% (n = 57), respectively. Nineteen (16.4%) patients were readmitted within 30 days of discharge, of which none were pain related. When compared to ECUD, patients who received ICUD experienced similar complication and readmission rates.

CONCLUSIONS

The implementation of a NOP protocol for patients undergoing RARC with ICUD allows for both decreased postoperative narcotic use and reduced need for narcotic prescriptions at discharge with acceptable complication and readmission rates.

Long-acting liposomal bupivacaine and postoperative opioid use after Peyronie's disease surgery: a pilot study

Background

Novel strategies have been proposed to minimize postoperative opioid use, yet many patients experience significant pain after penile surgery. Our objective was to evaluate postoperative opioid use in patients undergoing penile ring block with long-acting liposomal bupivacaine (LB; Exparel) during surgery for Peyronie's disease (PD).

Methods

We identified patients who underwent tunica albuginea plication (TAP) and plaque excision/grafting (PEG) for PD between July 2019 and September 2020. Intraoperatively, a ring block was administered at the penile base penis with 20 cc of LB. Patients were instructed to use over the counter pain medications as first line treatment for postoperative pain, and opioids were available for severe breakthrough pain as needed [7.5 oral morphine equivalents (OME) =5 mg oxycodone]. Opioid use was assessed during the first five days postoperatively.

Results

In total, 28 patients met inclusion criteria including 18/28 (64%) who underwent TAP and 10/28 (36%) who underwent PEG. Median patient age was 56 years (IGR 51;61). Median postoperative 10-point visual analogue pain score was 0 (range 0-3). Duration of penile anesthesia ranged from 1.5-4 days. In total, 9/28 patients (32%) utilized opioids during the first five days postoperatively (range 7.5-75 OME). Two patients (7%) required opioids during the first two days after surgery. 27/28 (96%) were satisfied or highly satisfied with postoperative pain control.

Conclusions

Intraoperative penile ring block with LB resulted in excellent pain control with local anesthetic duration of 1.5-4 days. The majority of patients did not require any opioids during the early postoperative period. Further study comparing outcomes with shorter-acting local anesthetics is necessary to balance pain control benefits with additional cost.

Enhanced recovery after spine surgery: a systematic review

OBJECTIVEEnhanced recovery after surgery (ERAS) is a multidimensional approach to improving the care of surgical patients using subspecialty- and procedure-specific evidence-based protocols. The literature provides evidence of the benefits of ERAS implementation, which include expedited functional recovery, decreased postoperative morbidity, reduced costs, and improved subjective patient experience. Although extensively examined in other surgical areas, ERAS principles have been applied to spine surgery only in recent years. The authors examine studies investigating the application of ERAS programs to patients undergoing spine surgery.METHODSThe authors conducted a systematic review of the PubMed and MEDLINE databases up to November 20, 2018.RESULTSTwenty full-text articles were included in the qualitative analysis. The majority of studies were retrospective reviews of nonrandomized data sets or qualitative investigations lacking formal control groups; there was 1 protocol for a future randomized controlled trial. Most studies demonstrated reduced lengths of stay and no increase in rates of readmissions or complications after introduction of an ERAS pathway.CONCLUSIONSThese introductory studies demonstrate the potential of ERAS protocols, when applied to spine procedures, to reduce lengths of stay, accelerate return of function, minimize postoperative pain, and save costs.

Benefits of Enhanced Recovery After Surgery in Patients Undergoing Endoscopic Sinus Surgery

Background

Although enhanced recovery after surgery (ERAS) protocols have been widely applied during perioperative periods for different diseases, there are few reports of ERAS in patients undergoing endoscopic sinus surgery (ESS). This study therefore aimed to evaluate the benefits of ERAS protocol compared to traditional care following ESS.

Methods

A total of 55 patients with chronic rhinosinusitis undergoing ESS were prospectively assigned to 1 of 5 treatment groups; ERAS groups with postoperative intravenous Flubiprofen Axetil or analgesia pump, traditional care with Flubiprofen Axetil or analgesia pump (NERAS groups), or traditional care without postoperative intravenous analgesia group (control). All patients completed the Kolcaba General Comfort Questionnaire, Medical Outcomes Study Sleep Scale, and Self-rating Anxiety Scale at admission and before discharge. Pain scores were recorded at 2, 6, 24, and 48 hours postsurgery and adverse reactions to analgesics were noted.

Results

Patients in ERAS group demonstrated significantly higher general comfort scores and lower self-rating anxiety scores compared to patients in NERAS and control groups. Compared to control patients, patients in ERAS group reported significantly lower pain scores at 6, 24, and 48 hours. Moreover, pain alleviated from 6 hours postsurgery in ERAS group compared to 48 hours in NERAS group. Patients using opioids experienced more adverse nausea events than patients using only nonsteroidal anti-inflammatory drugs (NSAIDs).

Conclusions

The use of patient-tailored ERAS programs following ESS may help to attain higher general comfort and to alleviate perioperative anxiety compared with traditional perioperative care. Adequate postoperative analgesia with NSAIDs in ERAS protocol may alleviate pain earlier with fewer adverse reactions.
