Postoperative C-reactive protein concentration and clinical outcome: comparison of open cystectomy to robot-assisted laparoscopic cystectomy with extracorporeal or intracorporeal urinary diversion in a prospective study

Feasibility and safety of laparoscopic radical cystectomy for male octogenarians with muscle-invasive bladder cancer

This study was designed to evaluate the safety and feasibility of laparoscopic radical cystectomy (LRC) for male octogenarian patients with muscle-invasive bladder cancer (MIBC). Briefly, a total of 57 male octogenarian patients (A group) with bladder carcinoma were enrolled and underwent LRC and intracorporeal pelvic lymph node dissection with bilateral cutaneous ureterostomy from May 2016 to December 2022. Besides, 63 male patients (age < 80 years old) with bladder carcinoma undergoing LRC and 17 octogenarian male patients with bladder carcinoma undergoing open radical cystectomy (ORC) were enrolled in B and C groups as control. All perioperative clinical materials and outcomes of long-term follow-up, and complication were collected. The specific results were shown as follows. Compared with C group, the operation time and resected lymph node in A group was increased, and the estimated blood loss, the number of transfusion needed, duration of pelvic drainage and hospital stay after surgery was decreased. The death rate and ileus complication rate were higher in A group (12 cases) than in C group (15 cases). The cases of ureteral stricture in A group (13 cases) was decreased compared with that in C group. Overall, LRC and bilateral cutaneous ureterostomy are safe, feasible and better choices for the treatment of male octogenarian patients with MIBC. The octogenarian receiving cutaneous ureterostomy heals slowly and exists certain incomplete intestinal obstruction after surgery.

Robot-assisted radical cystectomy with intracorporeal urinary diversion: an updated systematic review and meta-analysis of its differential effect on effectiveness and safety

BACKGROUND

Robot-assisted laparoscopic cystectomy with intracorporeal urinary diversion (iRARC) is increasingly being used in recent years. Whether iRARC offers advantages over open radical cystectomy (ORC) remains controversial. This study aimed to compare the difference of perioperative outcomes, oncological outcomes and complications between iRARC and ORC.

METHODS

The PubMed, Embase, Cochrane Library, Web of Science and CNKI databases were searched in July 2023 according to the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement. Studies were identified to be eligible if they compared perioperative outcomes, oncological outcomes and complications in patients who underwent iRARC with ORC.

RESULTS

Twenty-two studies involving 7,020 patients were included. Compared to ORC, iRARC was superior for estimated blood loss [EBL WMD: -555.52; 95% CI, -681.64 to -429.39; P<0.001], blood transfusion rate [OR: 0.16; 95% CI, 0.09 to 0.28; P<0.001], length of hospital stay [LOS WMD: -2.05; 95% CI, -2.93 to -1.17; P<0.001], Clavien-Dindo grades ≥III complication rate [30d: OR: 0.57; 95% CI 0.44 to 0.75; P<0.001; 90d: OR: 0.71; 95% CI 0.60 to 0.84; P<0.001], and positive surgical margin [PSM OR: 0.65; 95% CI 0.49 to 0.85; P=0.002]. However, iRARC had a longer operative time [OT WMD: 68.54; 95%CI 47.41 to 89.67; P<0.001] and a higher rate of ureteroenteric stricture [ UES OR: 1.56; 95% CI 1.16 to 2.11; P=0.003]. Time to flatus, time to bowel, time to regular diet, readmission rate, Clavien-Dindo grades

CONCLUSION

Robot-assisted laparoscopic cystectomy with intracorporeal urinary diversion appears to be superior to open radical cystectomy in terms of effectiveness and safety. However, attention should be paid to the occurrence of ureteroenteric stricture during follow-up.

Nursing Intervention Countermeasures of Robot-Assisted Laparoscopic Urological Surgery Complications

The objective is to explore the application effect of comprehensive nursing intervention in prevention of lower extremity deep vein thrombosis and pulmonary embolism in urological patients undergoing laparoscopic and robot-assisted laparoscopic surgery. From April 2019 to April 2020, 200 patients who received urological laparoscopic surgery and robot-assisted laparoscopic surgery were selected. According to the random number table method, they were divided into control group and observation group, 100 cases in control group and 100 cases in observation group. Patients in control group received routine nursing, while patients in observation group received comprehensive nursing intervention. The skin condition, swelling, pain, and occurrence of deep venous thrombosis and pulmonary embolism of lower extremities in 2 groups were observed. The experimental results showed that the lower limb swelling, lower limb pain, and lower limb deep vein thrombosis in the control group were significantly higher than those in the observation group, but all patients were cured and discharged after taking effective symptomatic treatment and nursing measures in time. In the control group, pulmonary embolism occurred in 3 patients, all of whom died. There was no significant difference in skin changes of lower limbs (P > 0.05), and there were significant differences in other skin changes (P < 0.05). It proved that comprehensive nursing intervention can effectively prevent the formation of lower extremity deep vein thrombosis and pulmonary embolism in urological patients undergoing laparoscopic and robot-assisted laparoscopic surgery with high-risk factors.

Perioperative outcomes of intracorporeal robot-assisted radical cystectomy versus open radical cystectomy: A systematic review and meta-analysis of comparative studies

PURPOSE

To systematically review studies comparing the perioperative outcomes of intracorporeal robot-assisted radical cystectomy (iRARC) and open radical cystectomy (ORC).

METHODS

Systematic searches of PubMed, Web of Science and the Cochrane Library were performed in June 2020. Studies with data comparing iRARC and ORC were included in our review, and a pooled meta-analysis was completed.

RESULTS

In total, 8 studies (7 prospective studies, 1 retrospective study) comparing 1193 patients were included for our review and meta-analysis. Compared with ORC, iRARC demonstrated lower estimated blood loss (weighted mean difference (WMD): -449.25; 95% CI -566.47 - -332.03; p < 0.01), lower blood transfusion rates (OR: 0.31; 95% CI 0.22 - 0.46; p < 0.01), and lower postoperative complication rates with Clavien-Dindo grades III-IV (30 days: OR: 0.65; 95% CI 0.47 - 0.90; p = 0.01; 90 days: OR: 0.72; 95% CI 0.53 - 0.98; p = 0.04), but a longer operative time (WMD: 78.82; 95% CI 52.77 - 104.87; P < 0.01). Furthermore, there was no significant difference between iRARC and ORC in terms of postoperative complication rates with Clavien-Dindo grades Ⅰ-Ⅱ (30 days: OR: 0.71; 95% CI 0.36 - 1.40; p = 0.32; 90 days: OR: 0.98; 95% CI 0.74 - 1.30; p = 0.89), length of stay (WMD: -1.18; 95% CI -3.33 - -2.07; p = 0.06) and positive surgical margins (OR: 0.78; 95% CI 0.0.45 - 1.36; p = 0.38).

CONCLUSION

iRARC was associated with a significantly lower estimated blood loss and a lower blood transfusion rate and major postoperative complication rate than ORC.

Intracorporeal versus extracorporeal urinary diversion in robot-assisted radical cystectomy: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to assess and compare the perioperative and oncological outcomes of intracorporeal (ICUD) and extracorporeal (ECUD) urinary diversion following robot-assisted radical cystectomy (RARC). A systematic literature search of articles was performed in PubMed^®, Web of Science^®, and Scopus^® databases according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. We included studies that compared patients who underwent RARC with ICUD to those with ECUD. Twelve studies including 3067 patients met the eligibility criteria. There were no significant differences between ICUD and ECUD in overall and major complications, regardless of the period (short-term [≤ 30 days] or mid-term [> 30 days]). Subgroup analyses demonstrated that ICUD performed by high-volume centers exhibited a significantly reduced risk of major complications (short-term: OR 0.57, 95% CI 0.37–0.86, p = 0.008, mid-term: OR 0.66, 95% CI 0.46–0.94, p = 0.02). Patients who underwent ICUD had lower estimated blood loss (MD -102.3 ml, 95% CI − 132.8 to − 71.8, p < 0.00001), less likely to receive blood transfusion rates (OR 0.36, 95% CI 0.20–0.62, p = 0.00003); and these findings were consistent in subgroup analyses by low-volume centers (MD-121.6 ml, 95% CI − 160.9 to − 82.3, p < 0.00001 and OR 0.36, 95% CI 0.20–0.62, p = 0.00003, respectively). ICUD had a higher lymph node yield (MD 3.68, 95% CI 0.80–6.56, p = 0.01). Patients receiving ICUD provided comparable complications, superior perioperative outcomes, and similar oncological outcomes compared with ECUD. Centralization of patients may contribute to a reduction of postoperative complications, while maintaining the advantages.

Comparison of intracorporeal versus extracorporeal urinary diversion after robot-assisted radical cystectomy at a medium-sized facility

BACKGROUND

The aim of this study is to compare the perioperative outcomes and learning curves between intracorporeal and extracorporeal urinary diversion at our medium-sized institution.

METHODS

Between January 2018 and September 2020, a single surgeon at our institution performed 46 consecutive robot-assisted radical cystectomies with ileal conduit. We compared the perioperative outcomes between patients who underwent intracorporeal versus extracorporeal urinary diversion. We also investigated learning curves for the first and last 10 patients in each group.

RESULTS

The extracorporeal group had shorter overall operative time (P = 0.003) and urinary diversion time (P < 0.0001) than the intracorporeal group. The intracorporeal group had shorter length of hospital stay (P = 0.02). There was no difference in complication and readmission rates. The extracorporeal group demonstrated no difference between the first and last 10 patients for overall operative time or time for cystectomy, lymph node dissection, or urinary diversion. However, the intracorporeal group had shorter urinary diversion time for the last 10 patients compared with the first 10 patients. The first 10 patients in the extracorporeal group had shorter overall operative time than the first 10 in the intracorporeal group, but there was no difference for the last 10 patients.

CONCLUSIONS

Intracorporeal urinary diversion requires longer overall operative time than extracorporeal diversion for the first 10 patients, due to longer urinary diversion time. However, there is no difference in overall operative time for the last 10 patients. The benefit of intracorporeal over extracorporeal urinary diversion was not confirmed at our medium-sized institution.

Intracorporeal versus extracorporeal urinary diversion after robot-assisted radical cystectomy: a pooled analysis

Background

To compare intracorporeal urinary diversion (ICUD) with extracorporeal urinary diversion (ECUD) after robot-assisted radical cystectomy (RARC) for surgery safety, postoperative recovery, complication, and prognosis.

Methods

We performed a literature search on PubMed, Embase, Medline and the Cochrane Library based on all randomized controlled trials (RCTs) and observational comparative studies related to study topics published before July 14th, 2020. Then systematic review and meta-analysis was performed.

Results

13 retrospective studies containing 4,755 patients were identified. In terms of surgery safety, with similar operative time, ICUD group showed less estimated blood loss (EBL) (P<0.0001) and lower blood transfusion rate (P=0.006). In terms of postoperative recovery, with similar hospital stay, ICUD group showed earlier recovery on flatus (P<0.001) and oral intake (P<0001). In aspect of complications, there were no significant differences between ICUD and ECUD groups, except for gastrointestinal system complications. ICUD group had lower gastrointestinal complications rate than ECUD group (P=0.002). In aspect of prognosis outcomes, with similar mortality, ICUD group had lower recurrence rate than ECUD group (P=0.004).

Conclusions

Based on the current evidence, ICUD procedure is excellence in surgery safety, postoperative recovery, complications, and prognosis. However, the observational studies reduced the level of evidence, larger randomized trials are needed to confirm these findings.

Robot-Assisted Radical Cystectomy with Intracorporeal Urinary Diversion: A New Standard of Urinary Diversion

Background: To summarize the current evidence on robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) and compare perioperative outcomes and postoperative complications of patients undergoing RARC with extracorporeal urinary diversion (ECUD) and ICUD. Patients and Methods: Through a systematical search of multiple scientific databases in March 2020, we performed a systematic review and cumulative meta-analysis of the primary outcomes of interest. Also, we assessed the quality of the relevant evidence according to the framework in the Cochrane Handbook for Systematic Reviews of Interventions. Results: Thirteen studies with 4696 participants were included in this review. No significant differences were found between the ECUD and ICUD in operation time (OT) (mean difference [MD]: -6.45, 95% confidence interval [CI]: -35.20 to 22.30), length of stay (MD: 0.36, 95% CI: -0.81 to 1.54), 30-day overall complications (odds ratio [OR]: 0.92, 95% CI: 0.60-1.41), 30-day minor complications (OR: 1.36, 95% CI: 0.85-2.19), 30-day major complications (OR: 0.70, 95% CI: 0.34-1.43), 90-day overall complications (OR: 1.34, 95% CI: 0.83-2.18), and major complications (OR: 1.03, 95% CI: 0.68-1.57). However, less estimate blood loss (MD: 99.28 mL, 95% CI: 62.59-135.98), lower intraoperative blood transfusion (OR: 1.80, 95% CI: 1.09-2.95), shorter oral intake time (MD: 0.78, 95% CI: 0.43-1.14), and 90-day minor complications (OR: 1.72, 95% CI: 1.08-2.73) were associated with ICUD. The subgroup analysis showed less estimated blood loss (MD: 149.73, 95% CI: 21.33-278.13) and less OT (MD: 32.45, 95% CI: 14.37-50.53) were found in ICUD. Conclusions: The ICUD is a safe and feasible alternative to ECUD, which decreases the need for blood transfusion and reduces 90-day complications. However, further quality studies are needed to evaluate effectiveness of ICUD and its oncologic outcomes, functional outcomes, cost, and the quality of life.

Robot-assisted radical cystectomy with intracorporeal urinary diversion decreases postoperative complications only in highly comorbid patients: findings that rely on a standardized methodology recommended by the European Association of Urology Guidelines

INTRODUCTION

The available studies comparing robot-assisted radical cystectomy (RARC) with intracorporeal (ICUD) vs. extracorporeal (ECUD) urinary diversion have not relied on a standardized methodology to report complications and did not assess the effect of different approaches on postoperative outcomes.

MATERIALS

Two hundred and sixty seven patients treated with RARC at a single center were assessed. A retrospective analysis of data prospectively collected according to a standardized methodology was performed. Multivariable logistic regression models (MVA) assessed the impact of ICUD vs. ECUD on intraoperative complications, prolonged length of stay (LOS), 30-day Clavien Dindo (CD) ≥ 2 complications and readmission rate. Interaction terms tested the impact of the approach on different patient subgroups. Lowess graphically depicted the probability of CD ≥ 2 after ICUD or ECUD according to patient baseline characteristics.

RESULTS

Overall, 162 ICUD vs 105 ECUD (61 vs. 39%) were performed. Intraoperative complications were recorded in 24 patients. The median LOS and readmission rate were 11 vs. 13 (p = 0.02) and 24 vs. 22% (p = 0.7) in ICUD vs. ECUD, respectively. Overall, 227 postoperative complications were recorded. The overall rate of CD ≥ 2 was 35 and 43% in patients with ICUD vs. ECUD, respectively (p = 0.2). At MVA, the approach type was not an independent predictor of any postoperative outcomes (all p ≥ 0.4). Age-adjusted Charlson Comorbidity Index (ACCI) was associated with an increased risk of CD ≥ 2 (OR: 1.2, p = 0.006). We identified a significant interaction term between ACCI and approach type (p = 0.04), where patients with ICUD had lower risk of CD ≥ 2 relative to those with ECUD with increasing ACCI.

CONCLUSIONS

Relying on a standardized methodology to report complications, we observed that highly comorbid patients who undergo ICUD have lower risk of postoperative complications relative to those patients who received ECUD.

Does the Use of a Robot Decrease the Complication Rate Adherent to Radical Cystectomy? A Systematic Review and Meta-Analysis of Studies Comparing Open with Robotic Counterparts

Introduction: Radical cystectomy (RC) is the mainstay of treatment for muscle-invasive bladder cancer. In 2003, the first robot-assisted radical cystectomy (RARC) was performed and since then many studies, mainly observational, were conducted to compare robotic and open methods. This study aims to assess perioperative outcomes between the two methods based on pooled data from existing literature. Methods: A literature search of articles in English and French languages was performed in three databases (Medline, Embase, and Cochrane) until 30th of June 2018, as well as in urology conference programs and reference lists of included studies. The study protocol was registered at PROSPERO (CRD42018103063). Terms such as "robotic," "open," and "radical cystectomy" and synonyms were used for the searching algorithm. The primary outcome was the number of minor and major postoperative complications (Clavien grading system). Risk of bias was assessed with the Cochrane tool and Newcastle-Ottawa scale. Comparison of continuous outcomes was performed with weighted mean differences, while for dichotomous outcomes, odds ratios (ORs) were used. Review Manager 5.3 was used. Results: Fifty-four studies (5 randomized trials and 49 observational) were eligible, including 29,697 patients (6500 in the RARC group and 23,197 in the open radical cystectomy group). Minor complications (grade 1-2) in pooled data of 29 studies were fewer in the RARC group (OR = 0.54, 95% confidence interval [CI]: 0.38-0.76, p < 0.001), a difference persisting after sensitivity analysis for 30 and 90 days. Major complications (grade 3-5) in 31 studies were fewer in the RARC group (OR = 0.78, 95% CI: 0.65-0.94, p = 0.009), but this difference disappeared in the 30-day subanalysis. RARC was associated with lower blood transfusion rates (p < 0.001), lower length of stay (p < 0.001), faster return to regular diet (p < 0.001), and lower postoperative mortality rates (p < 0.001), but longer operating time. Conclusions: RARC appears to be associated with fewer complications and favoring perioperative outcomes in comparison with the open method. Due to the observational nature of most studies, larger randomized trials are needed to confirm these findings.

Comparison of perioperative complications and health-related quality of life between robot-assisted and open radical cystectomy: A systematic review and meta-analysis

To compare postoperative complications and health‐related quality of life of patients undergoing robot‐assisted radical cystectomy with those of patients undergoing open radical cystectomy. A systematic search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement. A pooled meta‐analysis was carried out to assess the differences between robot‐assisted radical cystectomy and open radical cystectomy according to randomized and non‐randomized comparative studies, respectively. We identified six randomized comparative studies and 31 non‐randomized comparative studies. Most robot‐assisted radical cystectomy patients were treated with extracorporeal urinary diversion. Robot‐assisted radical cystectomy was associated with longer operative times, and lower blood loss and transfusion rates compared with open radical cystectomy in both randomized comparative studies and non‐randomized comparative studies. There was no significant difference between robot‐assisted radical cystectomy and open radical cystectomy in the rate of patients with any or major complications within 90 days both in randomized comparative studies and non‐randomized comparative studies. Non‐randomized comparative studies reported a lower rate of complications at 30 days, mortality at 90 days and length of stay for patients treated with robot‐assisted radical cystectomy, which were not confirmed in randomized comparative studies. Additionally, there were no differences in postoperative quality of life score assessment at 3 and 6 months between robot‐assisted radical cystectomy and open radical cystectomy. Robot‐assisted radical cystectomy is associated with less blood loss and lower transfusion rates. There is no difference in complications, length of stay, mortality, and quality of life between robot‐assisted radical cystectomy and open radical cystectomy. Data from non‐randomized comparative studies favor perioperative outcomes in robot‐assisted radical cystectomy patients, the failure to confirm in randomized comparative studies, likely due to bias in study design and reporting. Further randomized comparative studies comparing postoperative complications and quality of life between robot‐assisted radical cystectomy with intracorporeal urinary diversion and open radical cystectomy are required to assess potential differences between these two surgical approaches.
