Association between Preoperative Albumin Levels and Length of Stay after Radical Cystectomy

Association between preoperative albumin and length of hospital stay in non-cardiac surgery patients with pulmonary hypertension: A secondary retrospective analysis

To explore the risk factors affecting the length of hospital stay (LOS) as well as to examine the relationship between preoperative serum albumin levels and LOS following non-cardiac, non-obstetric surgery in patients with pulmonary hypertension (PHTN). This study represents a secondary retrospective analysis based on 287 non-cardiac, non-obstetric procedures performed on 195 PTHN patients at a single institution in the USA between 2007 and 2013. The primary outcome was the LOS. We conducted a multiple logistic regression analysis to compare the LOS between the 2 groups, divided at a serum albumin level of 3.5 g/dL. After adjusting for multiple covariates, the ORs for the long length of stay (LOS > 7 days) for the high group(albumin > 3.5 g/dL) compared with the low group (albumin ≤ 3.5 g/dL) were 0.35 (95%CI: 0.21~0.6), 0.41 (95%CI: 0.22 ~0.76), 0.41 (95%CI: 0.18~0.94) from model 2 to model 4. The stratified analysis results indicate that these findings are stable (p for trend > 0.05). In this study, it was observed that low levels of preoperative albumin were associated with an increased risk of prolonged hospital stay after non-cardiac, non-obstetric surgery in patients with PHTN. This implies that optimizing preoperative nutrition could potentially reduce the LOS for non-cardiac, non-obstetric surgery in patients with PHTN.

Patient Safety and Quality Improvement in Minimally Invasive Surgery

Background: The journey of minimally invasive (MI) urology is one of quality improvement (QI) and patient safety. New techniques have been progressively studied for adoption and growth. As more advanced methods of data collection and analysis are developed, a review of the patterns and history of these principles in the development of MI urology can inform future urologic QI and patient safety initiatives. Objective: To perform a scoping review identifying patterns of QI and patient safety in MI urology. Methods: PubMed and the American Urological Association (AUA) journal search page were screened on December 2022 for publications using the search parameters "quality improvement" and "minimally invasive." Articles were screened according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews (PRISMA-ScR). Results: The initial literature search identified 471 articles from PubMed and 57 from the AUA journal search page. After screening, 528 articles were relevant to the topic and reviewed. Four hundred eighty-two articles were duplicates or did not meet inclusion criteria. Forty-six are included in this review. Conclusion: Urology has developed a pattern of assessing MI surgery vs the open counterpart. This includes analyzing the newest approach to understand complications, examining the factors contributing to complications, and lastly designing projects to mitigate future risk. This information, as well as advanced methods of data collection, has identified areas of improvement for new QI projects. The stage is set for a promising future with the adoption of advanced QI in daily urologic practice to improve patient safety and minimize errors.

The predictive value of the preoperative albumin-to-fibrinogen ratio for postoperative hospital length of stay in liver cancer patients

BACKGROUND

Hepatocellular carcinoma (HCC) is a significant global health burden, with postoperative hospital length of stay (LOS) impacting patient outcomes and healthcare costs. Existing nutritional, inflammatory, and coagulation indices can predict LOS, with particular interest in albumin, fibrinogen, and D-dimer. This study investigates the predictive value of preoperative albumin-to-fibrinogen ratio (AFR) and albumin-to-D-dimer ratio (ADR) for postoperative LOS in HCC patients.

METHODS

This retrospective study involved 462 adult HCC patients who underwent partial hepatic lesion excision between February 2016 and August 2022. We analyzed demographic and clinical data, including preoperative blood samples, surgical approach, and LOS. The primary outcome measure was LOS, calculated from the date of surgery to the date of hospital discharge. Preoperative AFR and ADR were calculated. The ROC curves determined optimal cutoff points. The Cox proportional hazards model, Kaplan-Meier method, and the log-rank test were used for statistical analysis.

RESULTS

The study established an optimal AFR cutoff value of 15.474, with a higher AUC value than ADR, indicating superior predictive potential for postoperative LOS. Participants with high-AFR (AFR > 15.474) had a shorter median LOS (13 vs. 15 days, p < 0.001) compared to those with low-AFR (AFR ≤15.474). Multivariate analysis revealed high-AFR (HR: 1.99; p < 0.001) as a positive influence on LOS reduction, whereas Child-Pugh rated as B (HR: 0.49; p < 0.001), laparotomy (HR: 0.37; p < 0.001) and total bilirubin >20.5 μmol/L (HR: 0.58; p < 0.001) negatively impacted LOS reduction. Subgroup analysis confirmed AFR's predictive ability for patients experiencing reduced or prolonged LOS due to Child-Pugh score, surgical methods, and total bilirubin concentrations. Even within normal albumin and fibrinogen levels, patients with high-AFR exhibited a shorter LOS (all p < 0.001).

CONCLUSIONS

Our findings underscore the value of the AFR as a reliable predictor of LOS in HCC patients. An AFR greater than 15.474 consistently correlated with a shorter LOS, suggesting its potential clinical utility in guiding perioperative management and resource allocation in HCC patients.

Perioperative Analgesic Efficiency of Ultrasound-Guided Quadratus Lumborum Block versus Epidural Analgesia in Bladder Cancer Patients Undergoing Radical Cystectomy

Background and Aim: Multimodal analgesia is currently used for perioperative pain management after Radical cystectomy (RC). This study aimed to compare quadratus lumborum block (QLB) and thoracic epidural block (TEA) in patients subjected to RC. Methods: This prospective randomized controlled study included 34 patients with bladder cancer subjected to RC under general anesthesia, divided into two groups. The Quadratus Group (n=17) underwent bilateral ultrasound-guided continuous QLB, and the Epidural Group (n=17) underwent continuous TEA. The primary outcome was pain intensity measured by VAS score, and the secondary outcomes were total morphine consumption during the first 48 hours after surgery, postoperative nausea score, and patient satisfaction. Results: There were no differences between the two groups in postoperative VAS scores starting immediately after surgery up to 48 hours. Reduction of VAS score after QLB was delayed compared to that after TEA. The two groups had a comparable number of patients requesting rescue analgesia (p = 0.271) and total postoperative morphine consumption (p = 0.976) in the remaining patients. The nausea score was significantly lower in the Quadratus Group than in the Epidural Group (p = 0.020). There was no significant difference between the two groups in the satisfaction score (p=0.612). Few mild complications were detected in the two studied groups. Conclusion: QLB and TEA are safe and effective in managing postoperative pain after radical cystectomy with similar analgesic profiles. QLB was more effective in reducing postoperative nausea and vomiting.

The impact of hypoalbuminemia on postoperative outcomes after outpatient surgery: a national analysis of the NSQIP database

PURPOSE

Hypoalbuminemia has been described as a modifiable factor to optimize postoperative outcomes after major inpatient surgeries. Nevertheless, the role of hypoalbuminemia on outpatient procedures is not well defined. The purpose of this study was to examine the impact of hypoalbuminemia on postoperative outcomes of patients undergoing low-risk outpatient surgery.

METHODS

Patients were extracted from the American College of Surgeons National Surgical Quality Improvement Program database who had outpatient surgery from 2018 and recorded preoperative albumin levels. The primary outcome was a composite of any major complications including: 1) unplanned intubation, 2) pulmonary embolism, 3) ventilator use > 48 hr, 4) progressive renal failure, 5) acute renal failure, 6) stroke/cerebrovascular accident, 7) cardiac arrest, 8) myocardial infarction, 9) sepsis, 10) septic shock, 11) deep venous thrombosis, and 12) transfusion. Death, any infection, and readmissions were secondary outcomes.

RESULTS

A total of 65,192 (21%) surgical outpatients had albumin collected preoperatively and 3,704 (1.2%) patients had levels below 3.5 g⋅dL-1. In the albumin cohort, 394/65,192 (0.6%) patients had a major medical complication and 68/65,192 (0.1%) patients died within 30 days after surgery. Albumin values < 3.5 g⋅dL-1 were associated with major complications (adjusted odds ratio [aOR], 1.92; 95% confidence interval [CI], 1.44 to 2.57; P < 0.001; death-adjusted OR, 3.03; 95% CI, 1.72 to 5.34; P < 0.001); any infection (aOR, 1.49; 95% CI, 1.23 to 1.82; P < 0.001); and readmissions (aOR, 1.82; 95% CI, 1.56 to 2.14; P < 0.001). In addition, when evaluated as a continuous variable in a multivariate analysis, for each increase in albumin of 0.10 g⋅dL-1, there was an associated reduction of major complications (aOR, 0.94; 95% CI, 0.92 to 0.96; P < 0.001).

CONCLUSIONS

Hypoalbuminemia is associated with major complications and death in outpatient surgery. Since hypoalbuminemia is a potential modifiable intervention, future clinical trials to evaluate the impact of optimizing preoperative albumin levels before outpatient surgery are warranted.

Is preoperative S-albumin associated to postoperative complications and readmission in patients with adult spinal deformity: a prospective analysis of 128 patients using the Spine AdVerse Event Severity (SAVES) system

PURPOSE

To assess the association between preoperative S-albumin and postoperative outcome following adult spinal deformity (ASD) surgery.

METHODS

All patients undergoing ASD surgery from February 1, 2017 and January 31, 2018 at a single quaternary referral center were prospectively included. Adverse events (AE) during admission were assessed using the Spine AdVerse Events Severity (SAVES) system. Based on preoperative S-albumin, patients were categorized as "normal" or "abnormal" and compared regarding postoperative outcome, adverse events (AEs), 30- and 90-day readmission, revision surgery, and mortality.

RESULTS

A total of 128 patients aged ≥ 18 years were included, and S-albumin was available in 88%. Of these, 73% (n = 93) were classified as "normal", 16% (n = 20) as "abnormal", and 12% (n = 15) as "missing". The "normal" albumin group had less comorbidity burden [ASA score 2 (2, 3) vs 3 (2, 3), p = 0.011], higher hemoglobin levels (8.4 (± 0.9) mmol/L vs 7.4 (± 1.1) mmol/L, p < 0.001), and higher S-albumin (38.9 (± 2.7) g/L vs 31.9 (± 4.4) g/L, < 0.001). The rate of 90-day readmission was significantly increased in the "abnormal" group (65% vs 36%), corresponding to a relative risk increase of 1.25 (95% CI 1.02-1.52, p = 0.029). Similar increased risks were found in subsequent logistic regression analyses, although results were not significant in multivariable analysis (p = 0.102). Comparing remaining outcome parameters, point estimates revealed increased AEs, 30-day readmission, and revision in the "abnormal" albumin group, although effects did not reach statistical significance.

CONCLUSIONS

In a prospective, consecutive, single-center cohort of 128 patients undergoing ASD surgery, we found a significant association between "abnormal" preoperative S-albumin and increased 90-day readmission. Furthermore, although the findings were not statistically significant, we did find that AEs, 30-day readmission, and revision were numerically more frequent in the "abnormal" group, suggesting an expected tendency that should be further investigated. We conclude that nutritional status prior to ASD surgery could be important to consider and suggest validation in larger prospective cohorts.

Complications and Discharge after Radical Cystectomy for Older Patients with Muscle-Invasive Bladder Cancer: The ELCAPA-27 Cohort Study

Simple Summary

Radical cystectomy is associated in older patients with an increased risk of post-operative complications. However, these studies did not take into account geriatric variables. In our study, all patients had a standardized geriatric assessment prior to radical cystectomy. Although geriatric variables were not associated with 30-day complications, our study found that frailty (measured as a G8 score ≤ 14), a loss of autonomy, anemia, and severe comorbidities were associated with a higher risk of not being discharged home at one month after the surgery.

Abstract

Radical cystectomy is the standard of care for localized bladder cancer but is associated with high morbidity and mortality rates—especially among older patients with comorbidities. The association between geriatric assessment parameters on post-operative complications and discharge has not previously been investigated. The present analysis of the Elderly Cancer Patient (ELCAPA) prospective cohort included all patients aged ≥70 having undergone a geriatric assessment and then radical cystectomy for localized muscle-invasive bladder cancer between 2007 and 2018. The primary endpoint was the proportion of patients with one or more complications in the first 30 days after cystectomy. The secondary endpoints were the length of hospital stay (LOS), the 30-day mortality, and discharge rates. Sixty-two patients (median age: 81; range: 79–83.8) were included. The 30-day complication rate was 73%, and 49% of the patients had experienced a major complication, according to the Clavien-Dindo classification. The 30-day mortality rate was 4%. None of the geriatric, oncological, or laboratory parameters were significantly associated with the occurrence or severity of complications. The median (interquartile range) LOS was 18 days (15–23) overall and was longer in patients with complications (19 days vs. 15 days in those without complications; p = 0.013). Thirty days after cystectomy, 25 patients (53%) had been discharged to home and 22 (47%) were still in a rehabilitation unit. In a univariate analysis, a Geriatric-8 score ≤ 14, a loss of one point on the Activities of Daily Living Scale, anemia, at least one grade ≥ 3 comorbidity on the Cumulative Illness Rating Scale-Geriatric, and an inpatient geriatric assessment were associated with a risk of not being discharged to home. In older patients having undergone a geriatric assessment, radical cystectomy is associated with a high complication rate, a longer LOS, and functional decline at 30 days.

Controlling Nutritional Status Score Before Receiving Treatment as a Prognostic Indicator for Patients With Urothelial Cancer: An Exploration Evaluation Methods

Introduction

This meta-analysis aims to assess whether the Controlling nutritional status (CONUT) score before treatment can be an independent predictor of the prognosis of patients with urothelial cancer (UC).

Methods

The system searches Web of Science, PubMed, MEDLINE, China National Knowledge Infrastructure (CNKI), and Cochrane Library, and the search time is up to April 2021. Use STATA 16.0 and Engauge Digitizer 4.1 software for data processing and statistical analysis.

Results

A total of 8 studies were included in this meta-analysis. The meta-analysis results show that compared with the low CONUT group, the high CONUT group has worse over survival (OS) [HR=1.58, 95%CI (1.34, 1.86), P=0.001], cancer-specific survival (CSS) [HR=2.03, 95%CI (1.25-3.29), P=0.04] and recurrence-free survival (RFS) [HR=1.97, 95%CI (1.15, 3.40), P=0.014]; for progression-free survival (PFS), or disease-free survival (DFS), the difference between the two groups was not statistically significant [HR=2.30, 95%CI (0.72, 7.32), P=0.158]. According to different carcinoma types, cut-off value, and region, subgroup analysis of OS was performed, and similar results were obtained.

Conclusions

Based on current evidence, this meta-analysis proves that the CONUT score of UC patients before treatment is an independent prognostic predictor. It performs well on OS, CSS, and RFS, but the conclusions on DFS/PFS need to be treated with caution.

Appendectomy and Cholecystectomy Outcomes for Pediatric Cancer Patients with Leukopenia: A NSQIP-pediatric Study

BACKGROUND

Children with cancer often develop leukopenia which may impair wound healing and increase surgical complication rates. When leukopenic children with cancer develop an acute surgical condition, the optimal management strategy remains unclear. This study examined the effect of preoperative leukopenia on postoperative outcomes in children with cancer who underwent an appendectomy or cholecystectomy.

METHODS

We retrospectively identified cancer patients undergoing an appendectomy or cholecystectomy from the National Surgical Quality Improvement Program-Pediatric database from 2012-2018. Demographics and perioperative characteristics were compared by leukopenia status (WBC <4 vs. ≥4 × 10^3/mL). Postoperative length of stay (LOS) and 30-day composite complications, including infections, reoperations, and readmissions, were analyzed for each procedure using multivariate regression.

RESULTS

There were 227 children who underwent an appendectomy and 101 children who underwent a cholecystectomy. Leukopenia was seen in 93 (41.0%) appendectomy and 57 (56.4%) cholecystectomy cases. Nineteen (8.4%) appendectomy patients and six (5.9%) cholecystectomy patients developed a postoperative complication. The median postoperative LOS was 2 days (IQR 1-6 days) for appendectomy and 1 day (IQR 1-2.5 days) for cholecystectomy cases. After multivariate analyses, leukopenia was not associated with increased postoperative complications after an appendectomy (OR 0.55, P = 0.36) or cholecystectomy (OR 0.39, P = 0.37). There was no significant difference in postoperative LOS based on leukopenia status for children who underwent an appendectomy (P = 0.82) or cholecystectomy (P = 0.37).

CONCLUSION

In pediatric cancer patients, leukopenia was not associated with increased short-term postoperative complications or longer postoperative LOS after either an appendectomy or cholecystectomy. These results support that operative management can be performed safely in pediatric appendicitis and cholecystitis in leukopenic cancer patients.

Short-Term Morbidity and Predictors of Adverse Events Following Esthesioneuroblastoma Surgery

INTRODUCTION

The short-term adverse events and predictors of morbidity in surgical resection of esthesioneuroblastoma (ENB) are largely unknown, and investigating these variables can help direct planning for at-risk patients.

METHODS

The 2005-2017 National Surgical Quality Improvement Program database was queried to identify patients with a diagnosis of ENB undergoing skull base surgery for tumor resection. Information regarding demographics, patient morbidity score, pre-operative and intra-operative data, and post-operative outcomes were extracted. Cox proportional hazard analysis was utilized to assess complication and readmission/reoperation rates.

RESULTS

A total of 95 patients undergoing skull base surgery for resection of ENB were included. Mean age, BMI, operation time, and post-operative length of stay (LOS) of the cohort were 53.6 ± 16.2 years, 29.1 ± 6.5, 392.0 ± 204.6 minutes, and 5.8 ± 4.6 days, respectively. In total, 31 patients (32.6%) experienced at least one 30-day adverse event, which included blood transfusion intra-operatively or within 72 hours from the operation (22.1%), readmission (10.7%), intubation >48 hours (7.4%), reintubation (4.2%), organ or space infection (4.2%), reoperation (4.0%), superficial or deep surgical site infection (2.1%), sepsis (2.1%), pulmonary embolism (1.1%), and myocardial infarction (1.1%). Patients who experienced at least one adverse event had significantly higher operation time (486.8 ± 230.4 vs. 347.5 ± 176.2 minutes, p = 0.002), LOS (9.2 ± 5.6 days vs. 4.2 ± 3.0, p < 0.001), and lower hematocrit (37.3 ± 5.9 vs. 41.2 ± 3.8, p < 0.001) and albumin levels (3.8 ± 0.6 vs. 4.2 ± 0.3, p = 0.009). Patients with a higher American Society of Anesthesiologists (ASA) score (HR = 2.39; p = 0.047) or longer operation time (HR = 1.004; p = 0.001) had a significantly higher risk for experiencing adverse events. Obesity was not associated with different intra- or post-operative outcomes, but older patients had shorter operations (p = 0.002) and LOS (p = 0.0014).

CONCLUSION

Longer operation time and lower pre-operative hematocrit and albumin levels may all increase complication rates in ENB resection. Patients with high ASA score or more advanced age may have different short-term outcomes.

A new index (A/G) associated with early complications of radical cystectomy and intestinal urinary diversion

OBJECTIVES

To put forward a new index (A/G, the postoperative ratio of albumin to blood glucose) associated with complications occurring within 30-day of radical cystectomy and intestinal urinary diversion (RC-IUD).

PATIENTS AND METHODS

The charts of 565 patients undergoing RC-IUD at our single center between 2008 and 2018 were reviewed. All baseline information and perioperative data were collected. We finally picked up 360 of them with complete postoperative laboratory test results to find a new index. Early complications (within 30-day) after surgery were graded using the standardized Clavien-Dindo scale. Single and multivariate logistic regression determined the association between perioperative variables and post RC-IUD complications.

RESULTS

A total of 485 men and 80 women with a median age of 61 years and BMI of 24.8 were included. As for intestinal urinary diversion, most patients (n = 513, 90.8%) received ileal conduits, 47 (8.3%) received Ileal orthotopic neobladders and 5 received Mainz pouch bladders (0.9%). Robotic surgeries were conducted in 311(55.0%) patients and other 254 (45.0%) accepted laparoscopic surgeries. Available laboratory markers were obtained from 359 cases. Postoperative complications occurred in 129 patients (22.8%), including 117 (90.7%) Minor (Clavien I or Clavien II events) complications, and 12 (9.3%) major (Clavien III or greater events) complications. A single logistic regression identified 4 variables associated with postoperative complications, including hypertension, surgical procedures, postoperative A/G, operating time, and blood loss. A further multivariate logistic regression identified 2 significant indices: operating time and postoperative A/G. Moreover, we built a receiver operating characteristic curve of A/G to identify a threshold of 3.65 as a new indicator of postoperative complication.

CONCLUSIONS

We put forward a new index named A/G associated with complications after radical cystectomy, not singular considering albumin or blood glucose any more. This novel related index may provide an early alert for RC-IUD patients thus aiding in directing individual rehabilitation and improving postoperative outcomes after RC-IUD.

The impact of preoperative nutritional status on post-surgical complication and mortality rates in patients undergoing radical cystectomy for bladder cancer: a systematic review of the literature

PURPOSE

To investigate the impact of preoperative nutritional factors [body mass index (BMI)], hypoalbuminemia (< 3.5 g/dL, sarcopenia) on complication and mortality rates after radical cystectomy (RC) for bladder cancer.

METHODS

The PubMed database was systematically searched for studies investigating the effect of nutritional status on postoperative outcomes after RC. English-language articles published between March 2010 and March 2020 were reviewed. For statistical analyses odds ratios (ORs) and hazard ratios (HRs) weighted mean was applied.

RESULTS

Overall, 81 studies were included. Twenty-nine studies were enrolled in the final analyses. Patients with a 25-29.9 kg/m² BMI (OR 1.55, 95% confidence interval [CI] 1.14-2.07) and those with a BMI ≥ 30 kg/m² (OR 1.73, 95% CI 1.29-2.40) had a significantly increased risk of 30 day complications after RC. Preoperative hypoalbuminemia increased the risk of 30 day complications (OR 1.56, 95% CI 1.07-2.35); it was a predictor of worse 3 year overall survival (OS) (HR 1.86, 95% CI 1.32-2.66). Sarcopenic patients had a higher risk of 90 day complications than non-sarcopenic ones (OR 2.49, 95% CI 1.22-5.04). Sarcopenia was significantly associated with unfavorable 5 year cancer-specific survival (CSS) (HR 1.73, 95% CI 1.07-2.80), and OS (HR 1.60, 95% CI 1.13-2.25).

CONCLUSION

High BMI, hypoalbuminemia, and sarcopenia significantly increased the complication rate after RC. Hypoalbuminemia predicted worse 3 year OS and sarcopenia predicted unfavorable 5 year CSS and OS. Preoperative assessment of RC patients' nutritional status is a useful tool to predict perioperative and survival outcomes.

Implementation of a Reduced Opioid Utilization Protocol for Radical Cystectomy

BACKGROUND: Radical cystectomy (RC) often requires a prolonged course of opioid medications for postoperative pain management. We implemented a Reduced Opioid Utilization (ROU) protocol to decrease exposure to opioid medications. OBJECTIVE: To determine the impact of the ROU protocol on opioid exposure, pain control, inpatient recovery, and complication rates among patients who underwent RC. METHODS: The ROU protocol includes standardized recovery pathways, a multimodal opioid-sparing pain regimen, and improved patient and provider education regarding non-opioid medications. Opioid exposure was calculated as morphine equivalent dose (MED), and was compared between RC patients following the ROU protocol and patients who previously followed our traditional pathway. Opioid-related adverse drug events (ORADEs), pain scores, length of stay, and 90-day complications, readmission, and mortality were also compared between cohorts. RESULTS: 104 patients underwent RC, 54 (52%) of whom followed the ROU protocol. ROU patients experienced a statistically significant decrease in opioid exposure in the post-anesthesia care unit (p = 0.003) and during their postoperative recovery (85.7±21.0 MED vs 352.6±34.4 MED, p < 0.001). The ROU protocol was associated with a statistically significant decrease in ORADEs after surgery. There was no significant difference in average pain scores, length of stay, readmissions, or 90-day complication or mortality rates. CONCLUSIONS: The ROU protocol decreased opioid use by 77% without compromising pain control or increasing the rate of complications. This study demonstrates the efficacy of non-opioid medications in controlling postoperative pain, and highlights the role providers can play to decrease patient exposure to opioids after RC surgery.

Epidural Anesthesia is Associated With Increased Complications in Cystectomy Patients: A NSQIP Analysis

OBJECTIVE

To identify differences in short-term outcomes and readmission rates in cystectomy patients managed with general anesthesia compared to those undergoing general anesthesia and adjuvant epidural anesthesia.

METHODS

Utilizing the National Surgical Quality Inpatient Program database, patients who underwent a cystectomy with ileal conduit between 2014 and 2017 were included. Patients were further subdivided based on additional anesthesia modality; general anesthesia vs general anesthesia plus epidural anesthesia. Propensity score-matching was used to adjust for baseline differences between cohorts using 1:1 caliper width of 0.15 for the propensity score through the nearest neighbor. Stepwise multivariable logistic regression was used to identify preoperative and intraoperative predictors associated with 30-day procedure related readmission, complications, and length of stay.

RESULTS

About 2956 patients met our inclusion and exclusion criteria and eligible for propensity score matching. Compared to general anesthesia, adjuvant epidural anesthesia showed an increased odds of procedure related complications (adjusted Odds Ratio (aOR): 1.264, 95% CI: 1.019-1.567, P = .033). There was an increased trend for development of pulmonary emboli (13 [1.8%] vs 4 [0.5%], P = .051) in the adjuvant epidural cohort. Combined general with epidural anesthesia demonstrated no difference in length of stay, readmission, or reoperation rate in comparison to general anesthesia alone.

CONCLUSION

Cystectomy patients who underwent general anesthesia plus epidural anesthesia demonstrated a higher percentage of any procedural related complication without change in postoperative stay, reoperation rate, or readmission rate compared to patients undergoing general anesthesia alone.

Robotic vs. open cystectomy: How length-of-stay differences relate conditionally to age

OBJECTIVES

The length-of-stay (LOS) benefit of minimally invasive cystectomy varies in the published literature, potentially because of subgroup effects. Here, we investigated the effect of minimally invasive cystectomy on LOS among different age groups.

METHODS AND MATERIALS

Adult patients who underwent cystectomy (open or minimally invasive) from January 1, 2012, to December 31, 2016, were identified from the National Surgical Quality Improvement Program database. Multivariable linear regression was used to evaluate the adjusted association between the surgical approach and LOS after stratifying patients by age (40-64, 65-79, and ≥80 years). A sensitivity analysis was performed after multiple imputation by using age as a continuous variable with a third-order polynomial term.

RESULTS

Of the 5,561 patients identified, 640 underwent minimally invasive cystectomy and 4,921 had open cystectomy. The unadjusted analysis showed that minimally invasive cystectomy was associated with a shorter mean LOS compared with the open approach (8.0 vs. 9.7 days; P < 0.001). The predicted difference in LOS between the 2 approaches was 0.72 days (95% confidence interval (CI), -0.28 to 1.72; P = 0.16) for patients aged 40 to 64 years, 1.48 days (95% CI, 0.73-2.23; P < 0.001) for 65 to 79 years, and 2.56 days (95% CI, 0.84-4.29; P = 0.01) for ≥80 years favoring the minimally invasive approach. The sensitivity analysis did not materially change the results.

CONCLUSIONS

Older patients may derive more LOS benefit from minimally invasive approaches than younger patients. Given the greater expense associated with the minimally invasive approach, an age-adapted strategy to using this technology may be reasonable.

[Limits of surgery in uro-oncology]

The limits of cancer surgery in uro-oncology are characterized by a carefully weighed risk of surgical feasibility and oncological necessity. The limits of uro-oncological cancer surgery do not represent fixed dogmas but ideally these more or less cognitive boundaries move based on new scientific findings, improved imaging modalities, optimized surgical techniques and perioperative care. The limits of cancer surgery are defined by patient-specific parameters, the biological aggressiveness of the tumor itself, the skills and expertise of the surgeon, and adequate perioperative care of the patient. Dependent on the origin of the cancers of the upper and lower urogenital tract, the specific particularities of each individual cancer in terms of prognosis need to be known, taking into consideration the newest molecular insights and modern multimodality treatment regimes. Only the consideration of the above mentioned basics will allow the best decision to be made with the patient concerning the optimal individual treatment. The current article highlights general parameters of the patient, tumor and surgeon which might define the limits of cancer surgery in uro-oncology. In addition, specific clinical scenarios are discussed with regard to surgery limits in cancer of the kidney, the prostate and the testis.
