First case report of robot-assisted radical cystectomy and intracorporeal urinary diversion using the hinotori Surgical Robot System.

ABSTRACT:

Background

The field of robotic surgery is still continuously advancing, with several cutting-edge robotic systems currently under development. This study aimed to present the methodology and perioperative outcomes of robot-assisted radical cystectomy (RARC) and intracorporeal urinary diversion (ICUD) in patient with muscle invasive bladder cancer (MIBC) by utilizing the hinotori Surgical Robot System, a recently developed robot-assisted surgical platform.

Case description

A 79-year-old man with MIBC, cT2N0M0, received RARC and ICUD after two courses of neoadjuvant chemotherapy. We performed RARC and ICUD using hinotori, with a total operation time of 476 minutes. The insufflation time was 424 minutes, and the console time was 396 minutes. Total blood loss was 562 mL and no blood transfusion was necessary. During the perioperative period, a paralytic ileus occurred, although no severe adverse events were observed. The pathological examination showed ypT0N0M0, and no recurrence was observed by computed tomography scan up to 8 months postoperatively.

Conclusions

This report demonstrates the successfully implementation of RARC and ICUD using the hinotori system, without perioperative adverse effects. While further exploration is required to assess the long-term and large-scale implications of RARC and ICUD using hinotori on oncologic and functional outcomes, these initial findings suggest that the hinotori Surgical Robot System holds promise as an application for RARC and ICUD in patients with MIBC.

Project description:ObjectivesTo assess the comparative effectiveness of robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) vs open radical cystectomy (ORC) for bladder cancer (BC).Patients and methodsWe conducted a real-life monocentric study including all consecutive patients who underwent RARC with ICUD or ORC for BC at our institution from 2014 to 2023. Uni- and multivariable logistic and Cox regression analyses were used to compare perioperative, oncological and stricture outcomes between both groups by calculating odds (ORs) and hazard (HRs) ratios with their corresponding 95% confidence intervals (CIs), respectively.ResultsOverall, 316 patients underwent either RARC with ICUD (n = 228 [72.2%]) or ORC (n = 88 [27.8%]). The perioperative benefits of RARC vs ORC included decreased risks of major blood loss (OR 0.10, 95% CI 0.04-0.23; P < 0.001), perioperative transfusion (OR 0.30, 95% CI 0.16-0.57; P < 0.001), 90-day major complications (OR 0.56, 95% CI 0.29-0.99; P = 0.04), and prolonged initial length of hospital stay (OR 0.20, 95% CI 0.09-0.35; P < 0.001), as well as more days alive and out of the hospital within 90 days of surgery (OR 2.56, 95% CI 1.46-4.6; P < 0.01). In addition, the use of RARC vs ORC was associated with a higher lymph node (LN) count (OR 3.35, 95% CI 1.83-6.30; P < 0.001), while there was no significant difference in recurrence-free (HR 0.72, 95% CI 0.49-1.07; P = 0.1), cancer-specific (HR 0.69, 95% CI 0.43-1.10; P = 0.1), overall (HR 0.76, 95% CI 0.47-1.20; P = 0.3) and uretero-ileal stricture-free (HR 1.18, 95% CI 0.62-2.25; P = 0.6) survival between both groups after a median (interquartile range) follow-up of 42.3 (16.4-73.8) months.ConclusionOur real-world study supports the effectiveness of RARC with ICUD vs ORC for BC. We generally observed better perioperative outcomes, as well as similar oncological-except for higher LN count-and uretero-ileal stricture outcomes after RARC with ICUD vs ORC.

Project description:IntroductionBladder cancer (BC) is a common malignancy and one of the most expensive to manage. Radical cystectomy (RC) with pelvic lymphadenectomy is a gold standard treatment for high-risk BC. Reductions in morbidity and mortality from RC may be achieved through robot-assisted RC (RARC). Prospective comparisons between open RC (ORC) and RARC have been limited by sample size, use of extracorporeal reconstruction and use of outcomes important for ORC. Conversely, while RARC is gaining in popularity, there is little evidence to suggest it is superior to ORC. We are undertaking a prospective randomised controlled trial (RCT) to compare RARC with intracorporeal reconstruction (iRARC) and ORC using multimodal outcomes to explore qualitative and quantitative recovery after surgery. METHODS AND ANALYSIS: iROC is a multicentre prospective RCT in English National Health Service (NHS) cancer centres. We will randomise 320 patients undergoing RC to either iRARC or ORC. Treatment allocation will occur after trial entry and consent. The primary outcome is days alive and out of hospital within the first 90 days from surgery. Secondary outcomes will measure functional recovery (activity trackers, chair-to-stand tests and health related quality of life (HRQOL) questionnaires), morbidity (complications and readmissions), cost-effectiveness (using EuroQol-5 Domain-5 levels (EQ-5D-5L) and unit costs) and surgeon fatigue. Patients will be analysed according to intention to treat. The primary outcome will be transformed and analysed using regression. All statistical assumptions will be investigated. Secondary outcomes will be analysed using appropriate regression methods. An internal feasibility study of the first 30 patients will evaluate recruitment rates, acceptance of randomised treatment choice, compliance outcome collection and to revise our sample size.Ethics and disseminationThe study has ethical approval (REC reference 16/NE/0418). Findings will be made available to patients, clinicians, funders and the NHS through peer-reviewed publications, social media and patient support groups.Trial registration numbersISRCTN13680280 and NCT03049410.

Project description:ImportanceRobot-assisted radical cystectomy is being performed with increasing frequency, but it is unclear whether total intracorporeal surgery improves recovery compared with open radical cystectomy for bladder cancer.ObjectivesTo compare recovery and morbidity after robot-assisted radical cystectomy with intracorporeal reconstruction vs open radical cystectomy.Design, setting, and participantsRandomized clinical trial of patients with nonmetastatic bladder cancer recruited at 9 sites in the UK, from March 2017-March 2020. Follow-up was conducted at 90 days, 6 months, and 12 months, with final follow-up on September 23, 2021.InterventionsParticipants were randomized to receive robot-assisted radical cystectomy with intracorporeal reconstruction (n = 169) or open radical cystectomy (n = 169).Main outcomes and measuresThe primary outcome was the number of days alive and out of the hospital within 90 days of surgery. There were 20 secondary outcomes, including complications, quality of life, disability, stamina, activity levels, and survival. Analyses were adjusted for the type of diversion and center.ResultsAmong 338 randomized participants, 317 underwent radical cystectomy (mean age, 69 years; 67 women [21%]; 107 [34%] received neoadjuvant chemotherapy; 282 [89%] underwent ileal conduit reconstruction); the primary outcome was analyzed in 305 (96%). The median number of days alive and out of the hospital within 90 days of surgery was 82 (IQR, 76-84) for patients undergoing robotic surgery vs 80 (IQR, 72-83) for open surgery (adjusted difference, 2.2 days [95% CI, 0.50-3.85]; P = .01). Thromboembolic complications (1.9% vs 8.3%; difference, -6.5% [95% CI, -11.4% to -1.4%]) and wound complications (5.6% vs 16.0%; difference, -11.7% [95% CI, -18.6% to -4.6%]) were less common with robotic surgery than open surgery. Participants undergoing open surgery reported worse quality of life vs robotic surgery at 5 weeks (difference in mean European Quality of Life 5-Dimension, 5-Level instrument scores, -0.07 [95% CI, -0.11 to -0.03]; P = .003) and greater disability at 5 weeks (difference in World Health Organization Disability Assessment Schedule 2.0 scores, 0.48 [95% CI, 0.15-0.73]; P = .003) and at 12 weeks (difference in WHODAS 2.0 scores, 0.38 [95% CI, 0.09-0.68]; P = .01); the differences were not significant after 12 weeks. There were no statistically significant differences in cancer recurrence (29/161 [18%] vs 25/156 [16%] after robotic and open surgery, respectively) and overall mortality (23/161 [14.3%] vs 23/156 [14.7%]), respectively) at median follow-up of 18.4 months (IQR, 12.8-21.1).Conclusions and relevanceAmong patients with nonmetastatic bladder cancer undergoing radical cystectomy, treatment with robot-assisted radical cystectomy with intracorporeal urinary diversion vs open radical cystectomy resulted in a statistically significant increase in days alive and out of the hospital over 90 days. However, the clinical importance of these findings remains uncertain.Trial registrationISRCTN Identifier: ISRCTN13680280; ClinicalTrials.gov Identifier: NCT03049410.

Project description:ObjectivesTo assess the utilisation trends of robot-assisted radical cystectomy (RARC), rates of performing continent urinary diversions (CUDs), and impact of diffusion of RARC on CUD rates.MethodsWe investigated the National Cancer Database for patients with muscle-invasive bladder cancer (MIBC) who underwent RC between 2004 and 2015. Patients were stratified by surgical technique into open (ORC) and RARC groups, and by type of urinary diversion into continent (CUD) and ileal conduit (ICUD) groups. Linear regression models were fitted to evaluate time trends for surgery and conversion techniques. Multivariate logistic regression models were utilised to identify independent predictors of RARC and CUD.ResultsA total of 14466 patients underwent RC for MIBC, of which 4914 (34%) underwent RARC. There was a significant increase in adoption of RARC from 22% in 2010 to 40% in 2015 (R2 = 0.96, P < 0.001), this was not associated with a change in the rates of CUD over the same period (P = 0.22). Across all years, ICUD was the primary type of urinary diversion, CUD was only offered in 12% in 2010 compared to 9.9% in 2015 (R2 = 0.33, P = 0.22). Multivariate analysis identified male gender (odds ratio [OR] 1.18, P = 0.03), academic centres (OR 1.74, P = 0.001), and lower T stage (T4 vs T2; OR 0.78, P = 0.03) as independent predictors of CUD, while surgical technique was not associated with odds of receiving CUD (P = 0.8).ConclusionsThere is significant nationwide increasing trend of adoption of RARC. This diffusion was not associated with a decline in CUD, which remains significantly underutilised in both ORC and RARC groups.
