Laparoscopic versus open radical cystectomy in 607 patients with bladder cancer: Comparative survival analysis

The clinical study of urinary flow parameters after drag-and-bond anastomosis for ileal orthotopic neobladder reconstruction

AIM

To assess the viability of this procedure in laparoscopic radical cystectomy with ileal orthotopic neobladder reconstruction, the objective of this study is to examine the relationship between urinary flow parameters of urethral drag-and-bond anastomosis in the reconstruction of the ileal orthotopic neobladder.

METHODS

36 patients with bladder cancer underwent laparoscopic radical cystectomy with ileal orthotopic neobladder reconstruction at Jiangxi provincial people's hospital between June 2016 and January 2021,16 patients underwent intermittent urethral anastomosis, while 20 patients underwent neobladder-urethral drag-and-bond anastomosis. The maximum bladder capacity, residual urine output, maximum urinary flow rate, and outlet morphology of the new bladder neck were all monitored throughout postoperative follow-up regularly.

RESULTS

There was no significant difference between the urethral drag-and-bond anastomosis group (group A) and the conventional anastomosis group (group B) at 3 months and 12 months after surgery, and the maximum bladder capacity (3 months, 488.35 ± 51.56 ml vs 481.06 ± 40.61 ml, t = -0.462, P = 0.647; 12 months, 496.35 ± 51.09 ml vs 476.56 ± 56.33 ml, t = -1.103, P = 0.278), residual urine output (3 months, 44.15 ± 24.12 ml vs 38.69 ± 21.82 ml, t = -0.704, P = 0.486;12 months, 49.65 ± 26.95 ml vs 36.75 ± 21.96 ml, t = -1.546, P = 0.131) and maximum urine flow rate (3 months, 12.36 ± 2.63 ml/s vs 13.60 ± 2.82 ml/s, t = 1.361, P = 0.182;12 months, 12.18 ± 3.14 ml/s vs 11.13 ± 3.01 ml/s, t = -1.004, P = 0.322) of the two groups were not significant (P > 0.05). The new bladder outlet morphology was not distorted in group A patients, the continuity was good, and there were fewer associated complications.

CONCLUSIONS

There was no significant difference in postoperative urodynamic parameters between the urethral drag-and-bond anastomosis group and the conventional anastomosis group, and the postoperative new bladder outlet was in good shape, with clinical significance.

Robotic-assisted radical cystectomy with cutaneous ureterostomies: a contemporary multicenter analysis

BACKGROUND

Robotic-assisted radical cystectomy (RARC) offers decreased blood loss during surgery, shorter hospital length of stay, and lower risk for thromboembolic events without hindering oncological outcomes. Cutaneous ureterostomies (UCS) are a seldom utilized diversion that can be a suitable alternative for a selected group of patients with competing co-morbidities and limited life expectancy.

OBJECTIVE

To describe operative and perioperative characteristics as well as oncological outcomes for patients that underwent RARC + UCS.

METHODS

Patients that underwent RARC + UCS during 2013-2023 in 3 centers (EU = 2, US = 1) were identified in a prospectively maintained database. Baseline characteristics, pathological, and oncological outcomes were analyzed. Descriptive statistics and survival analysis were performed using R language version 4.3.1.

RESULTS

Sixty-nine patients were included. The median age was 77 years (IQR 70-80) and the median follow-up time was 11 months (IQR 4-20). Ten patients were ASA 4 (14.5%). Nine patients underwent palliative cystectomy (13%). The median operation time was 241 min (IQR 202-290), and the median hospital stay was 8 days (IQR 6-11). The 30-day complication rate was 55.1% (grade ≥ 3a was 14.4%), and the 30-day readmission rate was 17.4%. Eleven patients developed metastatic recurrence (15.9%), and 14 patients (20.2%) died during the follow-up period. Overall survival at 6, 12, and 24 months was 84%, 81%, and 73%, respectively.

CONCLUSIONS

RARC + UCS may offer lower complication and readmission rates without the need to perform enteric anastomosis, it can be considered in a selected group of patients with competing co-morbidities, or limited life expectancy. Larger prospective studies are necessary to validate these results.

Impacts of enhanced recovery after surgery nursing interventions on wound infection and complications following bladder cancer surgery: A meta-analysis

A meta-analysis was executed to comprehensively examine the impacts of enhanced recovery after surgery (ERAS) care interventions on complications and wound infections following bladder cancer (BCa) surgery. Computer searches were carried out in Embase, Google Scholar, Cochrane Library, PubMed, Wanfang and CNKI, from their inception to November 2023, for RCTs regarding perioperative ERAS nursing interventions in patients with BCa. Two independent researchers performed literature screening, extracted data and carried out quality evaluations. Stata 17.0 software was utilized for the analysis of the data. Ultimately, 16 RCTs, involving 1190 patients, were included. The analysis showed that, in comparison with conventional nursing methods, perioperative ERAS nursing application in patients with BCa remarkably decreased the occurrence of wound infections (OR: 0.31, 95% CI: 0.16-0.59) and complications (OR: 0.19, 95% CI: 0.13-0.28). Our study indicates that perioperative care based on the ERAS concept remarkably decreased the occurrence of wound infections and complications following BCa surgery, demonstrating notable nursing efficacy and meriting widespread clinical promotion.

Comparative analysis of wound healing techniques in postoperative bladder cancer patients

Bladder cancer is a highly prevalent malignancy that presents significant difficulties in the management of wounds following surgery. The present study investigated the critical necessity to optimize wound healing techniques in patients undergoing bladder cancer surgery by contrasting conventional approaches with advanced modalities in order to promote recovery and mitigate complications. The study assessed the efficacy of conventional and advanced wound healing methods in these patients, taking into account the complex interaction of patient-specific factors and surgical complexities. A cross-sectional analysis was performed on 120 patients who underwent bladder cancer surgery at the first affiliated hospital of Wenzhou Medical University. In addition to medical record evaluations and direct wound assessments, patient interviews were utilized to gather information regarding demographics, surgical specifics, wound healing methodologies and postoperative results. Survival analysis and logistic regression were utilized in statistical analysis, with potential confounding variables such as age, comorbidities and type of surgery being accounted for. Advanced wound healing techniques, such as negative pressure wound therapy, tissue-engineered products, bioactive dressings and platelet-rich plasma (PRP), exhibited distinct advantage in comparison with conventional suturing. The aforementioned techniques, especially PRP, resulted in expedited wound healing, decreased rates of complications (p < 0.05) and enhanced secondary outcomes, including curtailed hospital stays and decreased rates of readmissions. PRP therapy, in particular, demonstrated significant improvements with the faster mean time to wound healing of 9 ± 2 days and lower complication incidence of 2 (6.7%) (p < 0.05), indicating its superior efficacy. A subgroup analysis revealed that younger patients, males and those undergoing laparoscopic surgery exhibited superior outcomes (p < 0.05). The results were further supported by logistic regression and Cox proportional hazards models, which further indicated that sophisticated techniques, notably PRP therapy with a hazard ratio of 3.00 (2.00-4.50) and adjusted odds ratio of 0.20 (0.09-0.43), were effective in improving postoperative recovery. The research clarified the significant advantages that advanced wound healing techniques offered in postoperative care of patients diagnosed with bladder cancer. By customizing these methods to suit the unique requirements of individual patients and specific circumstances of surgical procedures, they can significantly enhance the recuperation process after surgery and set a new standard for patient care.

Inpatient Outcomes of Patients Undergoing Robot-Assisted versus Laparoscopic Radical Cystectomy for Bladder Cancer: A National Inpatient Sample Database Study

Background: Bladder cancer is a common urinary tract malignancy. Minimally invasive radical cystectomy has shown oncological outcomes comparable to the conventional open surgery and with advantages over the open procedure. However, outcomes of the two main minimally invasive procedures, robot-assisted and pure laparoscopic, have yet to be compared. This study aimed to compare in-hospital outcomes between these two techniques performed for patients with bladder cancer. Methods: This population-based, retrospective study included hospitalized patients aged ≥ 50 years with a primary diagnosis of bladder cancer who underwent robot-assisted or pure laparoscopic radical cystectomy. All patient data were extracted from the US National Inpatient Sample (NIS) database 2008-2018 and were analyzed retrospectively. Primary outcomes were in-hospital mortality, prolonged length of stay (LOS), and postoperative complications. Results: The data of 3284 inpatients (representing 16,288 US inpatients) were analyzed. After adjusting for confounders, multivariable analysis revealed that patients who underwent robot-assisted radical cystectomy had a significantly lower risk of in-hospital mortality (adjusted OR [aOR], 0.50, 95% CI: 0.28-0.90) and prolonged LOS (aOR, 0.63, 95% CI: 0.49-0.80) than those undergoing pure laparoscopic cystectomy. Patients who underwent robot-assisted radical cystectomy had a lower risk of postoperative complications (aOR, 0.69, 95% CI: 0.54-0.88), including bleeding (aOR, 0.73, 95% CI: 0.54-0.99), pneumonia (aOR, 0.49, 95% CI: 0.28-0.86), infection (aOR, 0.55, 95% CI: 0.36-0.85), wound complications (aOR, 0.33, 95% CI: 0.20-0.54), and sepsis (aOR, 0.49, 95% CI: 0.34-0.69) compared to those receiving pure laparoscopic radical cystectomy. Conclusions: Patients with bladder cancer, robot-assisted radical cystectomy is associated with a reduced risk of unfavorable short-term outcomes, including in-hospital mortality, prolonged LOS, and postoperative complications compared to pure laparoscopic radical cystectomy.

Optimizing surgical outcomes in bladder cancer patients undergoing radical cystectomy

Purpose

To evaluate predictors of high-quality surgery and their effect on surgical outcomes in patients with bladder cancer undergoing radical cystectomy.

Evidence acquisition

A systematic and thorough review was performed to identify the most recent literature on current optimal management and predictors of high-quality surgery for patients undergoing radical cystectomy.

Conclusions

Muscle-invasive bladder cancer is an aggressive cancer requiring efficient and high-quality surgery in order to achieve the best oncological outcomes. Negative surgical margins, number of lymph nodes resected, lymph node dissection template, and surgical volume have been associated with improved oncologic outcomes. Robotic radical cystectomy continues to evolve and recent randomized controlled trials have shown that oncological outcomes are non-inferior when compared to the open technique. Regardless of approach, surgical technique should continually be evaluated and refined to optimize outcomes in patients undergoing radical cystectomy.

Low Intra-Abdominal Pressure with Complete Neuromuscular Blockage Reduces Post-Operative Complications in Major Laparoscopic Urologic Surgery: A before-after Study

Most urological interventions are now performed with minimally invasive surgery techniques such as laparoscopic surgery. Combining ERAS protocols with minimally invasive surgery techniques may be the best option to reduce hospital length-of-stay and post-operative complications. We designed this study to test the hypothesis that using low intra-abdominal pressures (IAP) during laparoscopy may reduce post-operative complications, especially those related to reduced intra-operative splanchnic perfusion or increased splanchnic congestion. We applied a complete neuromuscular blockade (NMB) to maintain an optimal space and surgical view. We compared 115 patients treated with standard IAP and moderate NMB with 148 patients treated with low IAP and complete NMB undergoing major urologic surgery. Low IAP in combination with complete NMB was associated with fewer total post-operative complications than standard IAP with moderate NMB (22.3% vs. 41.2%, p < 0.001), with a reduction in all medical post-operative complications (17 vs. 34, p < 0.001). The post-operative complications mostly reduced were acute kidney injury (15.5% vs. 30.4%, p = 0.004), anemia (6.8% vs. 16.5%, p = 0.049) and reoperation (2% vs. 7.8%, p = 0.035). The intra-operative management of laparoscopic interventions for major urologic surgeries with low IAP and complete NMB is feasible without hindering surgical conditions and might reduce most medical post-operative complications.

Bayesian network analysis of long-term oncologic outcomes of open, laparoscopic, and robot-assisted radical cystectomy for bladder cancer

BACKGROUND

To understand the long-term oncologic outcomes of open radical cystectomy (ORC) versus laparoscopic radical cystectomy (LRC) versus robot-assisted radical cystectomy (RARC) for bladder cancer (BCa). Therefore, we performed the conventional meta-analysis and network meta-analysis to evaluate the long-term oncologic outcomes of ORC, LRC, and RARC for BCa.

METHODS

A systematic search of PubMed, Embase, Cochrane Library, Medline, and Web of science was performed up until July 1, 2021. Long-term oncologic outcomes include the 5-year overall survival (OS) rate, the 5-year recurrence-free survival (RFS) rate, and the 5-year cancer specific-survival (CSS) rate. The Bayesian network analysis has been registered in PROSPERO (CRD42020208396).

RESULTS

We found that 10 articles (including 3228 patients) were included in our Bayesian network analysis. No significant differences were found between ORC, LRC, and RARC in long-term oncologic outcomes in either direct meta-analysis or network meta-analysis. Therefore, the clinical effects of 5-year OS, RFS, and CSS of RARC, LRC, and ORC are similar. But LRC may be ranked first in 5-year OS, RFS, and CSS compared to other surgical approaches by probabilistic analysis ranking via Bayesian network analysis.

CONCLUSION

We found that there were no statistical differences in the 3 surgical approaches of RAPC, LPC, and OPC for Bca in long-term oncologic outcomes by direct meta-analysis. However, Subtle differences between these surgical approaches can be concluded that LRC may be a better surgical approach than RARC or ORC in long-term oncologic outcomes by probabilistic analysis ranking via Bayesian network analysis. Moreover, we need a large sample size and more high-quality studies to improve and verify further.

Extraperitoneal laparoscopic radical cystectomy with intracorporeal neobladder: a comparison with transperitoneal approach

Background

Bladder cancer is one of the most common genitourinary cancers. Traditional transperitoneal radical cystectomy is the gold standard treatment for muscle-invasive bladder cancer. Our study was to compare the perioperative and oncological outcomes of extraperitoneal laparoscopic radical cystectomy (ELRC) with intracorporeal neobladder versus transperitoneal urinary diversion for bladder cancer.

Method

A total of 113 patients who underwent laparoscopic radical cystectomy performed at our center were included in this retrospective study. The perioperative data of the extraperitoneal laparoscopic radical cystectomy (ELRC) with intracorporeal urinary diversion (ICUD) and transperitoneal laparoscopic radical cystectomy (TLRC) with ICUD groups were compared. The demographic, perioperative, oncological, and complication data were collected and analyzed.

Results

In total, 113 patients were enrolled for the final analysis. The median follow-up period was 22 months. The ELRC group had shorter interval to flatus (p < 0.001), solid food (p < 0.001), shorter length of hospital stay (p < 0.01), and fewer early gastrointestinal complications (p < 0.05). Furthermore, urinary continence, recurrence-free, cancer-specific, and overall survival rates and recurrence patterns did not significantly differ.

Conclusions

Surgical technique of ELRC with ICUD can achieve the established oncologic criteria of TLRC, and such technique can improve perioperative and early postoperative outcomes.
