Experiences of a "COVID protected" robotic surgical centre for colorectal and urological cancer in the COVID-19 pandemic

Applicability and results of the versius surgical robotic system in colorectal surgery: a systematic review of the literature

Minimally invasive surgery has become the standard of care in colorectal surgery. However, the laparoscopic approach still presents technical challenges, especially when performing intracorporeal anastomosis or total mesorectal excision. Current literature underscores the potential of robotic-assisted surgery in overcoming these challenges. Among emerging robotic platforms, the Versius Surgical Robotic System, shows promises. However, its relatively recent introduction means there is a lack of data on its performances in colorectal surgery. This systematic review aimed to evaluate the current evidence on the use of Versius Surgical Robotic System in colorectal surgery. Following PRISMA 2020 guidelines, MEDLINE, CENTRAL, and EMBASE were systematically searched for original studies reporting on the use of the Versius Surgical Robotic System for colorectal surgery. Out of 199 publications screened, nine studies met the inclusion criteria for qualitative analysis. Most included studies were observational and monocentric studies, with the only large-scale, multicentric prospective data derived from the Versius surgical registry. A total of 561 colorectal procedures were reported, including oncological and benign disease, comprising 159 right hemicolectomies, 37 left colon or sigmoid resection, 253 low anterior resection and 64 abdominoperineal resections. The proportion of conversion to open surgery was 7.0% in the largest series and severe complications, defined as Clavien-Dindo grade 3 or higher was reported in 5.3% of cases. For right hemicolectomies, the mean operative time ranged from 160 to 221 min, with no conversion to open surgery reported and only one case requiring surgical revision. Intracorporeal anastomosis was reported in only one case. Regarding low anterior resection, the mean operative time ranged from 214 to 319 min, with a conversion rate to open of 6.9% and an incidence of severe complications of 6.0% in the largest series. Based on available literature there are no major safety concerns for the use of the Versius Surgical Robotic System for colorectal surgery. However, future well-conducted studies are needed to enable quantitative comparisons between different robotic platforms.

The Impact of COVID-19 Pandemic on the Diagnosis, Treatment, and Outcomes of Colorectal Cancer in Singapore

Background and Objectives: During the COVID-19 pandemic, many countries implemented lockdowns and social distancing measures, which may delay the early diagnosis of colorectal cancer (CRC). This study aims to review the impact of the pandemic on the diagnosis and treatment outcomes of CRC. Materials and Methods: Patients who underwent colonoscopy or surgery for CRC were included. The study was divided into the pre-COVID-19 (January 2019-January 2020), early COVID-19 (February-May 2020), recovery (June-December 2020), and heightened alert (January-December 2021) periods. Cox regression was used to model the waiting time to colonoscopy. Multivariable logistic regression identified associations between time periods and incidence of CRC diagnosed. The characteristics and outcomes of the surgical procedures that were performed were compared across the time periods. Results: A total of 18,662 colonoscopies and 1462 surgical procedures were performed in the study period. Compared to the pre-COVID-19 period, there was a longer time to colonoscopy during the recovery (HR: 0.91; 95% CI: 0.87, 0.94) and heightened alert periods (HR: 0.88; 95% CI 0.85, 0.91). The early COVID-19 (OR: 1.36; 95% CI: 1.04, 1.77) and recovery (OR: 1.20; 95% CI: 1.01, 1.43) periods were associated with higher odds of diagnosing CRC. Compared to the pre-COVID-19 period, there was a higher proportion of ASA 4 patients (4.3% vs. 1.3%; p < 0.001) and stage 4 CRC patients (22.2% vs. 16.9%; p = 0.001) that required surgery during the heightened alert period. Similarly, there was a higher proportion of emergency surgeries (22% vs. 13.3%; p = 0.002); diverting stomas (13.5% vs. 10.5%; p = 0.005), and Hartmann's procedures (4.4% vs. 0.4%; p = 0.001) performed during the heightened alert period. Conclusions: The pandemic was associated with a higher proportion of metastatic CRC patients requiring surgery. Healthcare policies should facilitate early cancer screening, diagnosis, and treatment to reduce cancer-related morbidity for future pandemics.

Extraperitoneal robot assisted laparoscopic prostatectomy with Versius system: single centre experience

INTRODUCTION

Versius Surgical System (CMR Surgical, Cambridge, UK) is a novel tele-operated robotic surgical system designed to assist surgeons for minimally invasive surgery which is gaining momentum in the world of robotic surgery. We describe our single centre experience with Versius and report the advantages and challenges posed by this new robotic system in a series of 53 extraperitoneal robotic assisted laparoscopic prostatectomies (eRALP) for prostate cancer (PCa).

MATERIALS AND METHODS

Data of 53 eRALP performed with Versius in our centre were collected and analysed, Descriptive statistics were used to report our results.

RESULTS

In 16 months we performed 53 eRALP: 18 (34%) with PLND, 33 (62%) nerve sparing cases. Mean setup time was 15 min, mean console time was 100 min and mean operative time was 130 min. We observed a substantial reduction of console time and set-up time after only 5 procedures. In the first 4 procedures, the dissection of the neurovascular bundle was performed laparoscopically, to switch back to robotic assisted approach afterwards. No major system failures were observed. No major intra-operative and post-operative complications occurred. Mean follow-up time was 9 months (range 3-15 months); no patients experienced biochemical recurrence or metastatic progression over this period, 8 (15%) patients had adjuvant radiotherapy based on unfavourable pathology report (positive surgical margins or positive limphnodes).

CONCLUSION

This represents to our knowledge the largest extraperitoneal RALP case series with Versius, and it aims to provide solid clinical proof of the safety, effectiveness and versatility of this innovative system. In our experience, this platform represents a good option for every urologic surgeon who wants to start a robotic programme and it appears particularly suitable for urologists with a large laparoscopic expertise.

Robotic inguinal hernia repair with the new Hugo RASTM system: first worldwide case series report

INTRODUCTION

Robotic-assisted surgery has been a part of surgical procedures for more than two decades. Recently new robotic platforms with a different design entered the market. The modular design with independent arms enables increased flexibility of arm docking to increase the range of motion and instrument maneuverability. We herein present the first case series of robotic inguinal hernia repair using the Hugo RAS system (Medtronic, Minneapolis, MN, USA).

MATERIAL AND METHODS

Thirteen inguinal hernia repairs were performed on ten patients. A description of the Hugo RAS system as well as the new concept of modular design is presented along with the description of the operation setup.

RESULTS

Mean docking time was 9.5 min and mean console time was 50.3 min and 74.7 min for unilateral and bilateral inguinal hernia repair, respectively. No intraoperative or postoperative complications occurred. There was one conversion to laparoscopic surgery due to a technical issue with the robot. Conclusions: The modular design of independent arms seems to enhance maneuverability of the instruments and contribute to fewer arm collisions. Further clinical data and experience with this new surgical system are necessary to understand if this new design has advantages over the standard robotic platforms.

Robotic Appendicectomy: A review of feasibility

Acute appendicitis is one of the most common abdominal emergencies. There has been an increasing use of robotic abdominal surgery. However, it remains underutilised in emergency settings. This study aimed to systematically review robotic appendicectomy (RA) feasibility. A 20-year systematic review was performed, along with quality assessment. The research protocol was registered with PROSPERO. The search yielded 1,242 citations, including 9 articles. The mean quality score was 10.72 ± 2.56. The endpoints across the studies were rate of conversion to open surgery, length of hospital stay, blood loss and operative time. RA is a safe, feasible technique that can be performed in elective and emergency settings with minimal blood loss. The operative time and hospital stay were within acceptable limits. Robotic surgery's major drawback is its high cost and limited availability. Future studies evaluating RA with a focus on its application during emergencies and its cost-effectiveness are recommended.

Global elective breast- and colorectal cancer surgery performance backlogs, attributable mortality and implemented health system responses during the COVID-19 pandemic: A scoping review

Globally, 28.4 million non-emergent ('elective') surgical procedures have been deferred during the COVID-19 pandemic. This study evaluated the impact of the COVID-19 pandemic on elective breast- or colorectal cancer (CRC) procedure backlogs and attributable mortality, globally. Further, we evaluated the interaction between procedure deferrals and health systems, internationally. Relevant articles from any country, published between December 2019-24 November 2022, were identified through searches of online databases (MEDLINE, EMBASE) and by examining the reference lists of retrieved articles. We organised health system-related findings thematically per the Structures-Processes-Outcomes conceptual model by Donabedian (1966). Of 337 identified articles, we included 50. Eleven (22.0%) were reviews. The majority of included studies originated from high-income countries (n = 38, 76.0%). An ecological, modelling study elucidated that global 12-week procedure cancellation rates ranged from 68.3%-73%; Europe and Central Asia accounted for the majority of cancellations (n = 8,430,348) and sub-Saharan Africa contributed the least (n = 520,459). The percentage reduction in global, institutional elective breast cancer surgery activity ranged from 5.68%-16.5%. For CRC, this ranged from 0%-70.9%. Significant evidence is presented on how insufficient pandemic preparedness necessitated procedure deferrals, internationally. We also outlined ancillary determinants of delayed surgery (e.g., patient-specific factors). The following global health system response themes are presented: Structural changes (i.e., hospital re-organisation), Process-related changes (i.e., adapted healthcare provision) and the utilisation of Outcomes (i.e., SARS-CoV-2 infection incidence among patients or healthcare personnel, postoperative pulmonary complication incidence, hospital readmission, length of hospital stay and tumour staging) as indicators of health system response efficacy. Evidence on procedure backlogs and attributable mortality was limited, partly due to insufficient, real-time surveillance of cancer outcomes, internationally. Elective surgery activity has decreased and cancer services have adapted rapidly, worldwide. Further research is needed to understand the impact of COVID-19 on cancer mortality and the efficacy of health system mitigation measures, globally.

Changes in Urologic Cancer Surgical Volume and Length of Stay During the COVID-19 Pandemic in Pennsylvania

Importance

Disruptions in cancer surgery during the COVID-19 pandemic led to widespread deferrals and cancellations, creating a surgical backlog that presents a challenge for health care institutions moving into the recovery phase of the pandemic.

Objective

To describe patterns in surgical volume and postoperative length of stay for major urologic cancer surgery during the COVID-19 pandemic.

Design, Setting, and Participants

This cohort study identified 24 001 patients 18 years or older from the Pennsylvania Health Care Cost Containment Council database with kidney cancer, prostate cancer, or bladder cancer who received a radical nephrectomy, partial nephrectomy, radical prostatectomy, or radical cystectomy between the first quarter (Q1) of 2016 and Q2 of 2021. Postoperative length of stay and adjusted surgical volumes were compared before and during the COVID-19 pandemic.

Main Outcomes and Measures

The primary outcome was adjusted surgical volume for radical and partial nephrectomy, radical prostatectomy, and radical cystectomy during the COVID-19 pandemic. The secondary outcome was postoperative length of stay.

Results

A total of 24 001 patients (mean [SD] age, 63.1 [9.4] years; 3522 women [15%], 19 845 White patients [83%], 17 896 living in urban areas [75%]) received major urologic cancer surgery between Q1 of 2016 and Q2 of 2021. Of these, 4896 radical nephrectomy, 3508 partial nephrectomy, 13 327 radical prostatectomy, and 2270 radical cystectomy surgical procedures were performed. There were no statistically significant differences in patient age, sex, race, ethnicity, insurance status, urban or rural status, or Elixhauser Comorbidity Index scores between patients who received surgery before and patients who received surgery during the pandemic. For partial nephrectomy, a baseline of 168 surgeries per quarter decreased to 137 surgeries per quarter in Q2 and Q3 of 2020. For radical prostatectomy, a baseline of 644 surgeries per quarter decreased to 527 surgeries per quarter in Q2 and Q3 of 2020. However, the likelihood of receiving radical nephrectomy (odds ratio [OR], 1.00; 95% CI, 0.78-1.28), partial nephrectomy (OR, 0.99; 95% CI, 0.77-1.27), radical prostatectomy (OR, 0.85; 95% CI, 0.22-3.22), or radical cystectomy (OR, 0.69; 95% CI, 0.31-1.53) was unchanged. Length of stay for partial nephrectomy decreased from baseline by a mean of 0.7 days (95% CI, -1.2 to -0.2 days) during the pandemic.

Conclusions and Relevance

This cohort study suggests that partial nephrectomy and radical prostatectomy surgical volume decreased during the peak waves of COVID-19, as did postoperative length of stay for partial nephrectomy.

Impact of the COVID-19 Pandemic on Colorectal Cancer Diagnosis and Treatment: a Systematic Review

BACKGROUND

Following the official announcement of the COVID-19 pandemic by the World Health Organization (WHO) in March 2020 and decreased activity of healthcare systems, relocation of resources, and the possible reluctance of patients to seek medical help, colorectal cancer patients were exposed to significant risks. Given that colon cancer is the third most common cancer and the second deadliest cancer in the world, its timely diagnosis and treatment are necessary to reduce costs and improve quality of life and patient survival. The aim of this study was to investigate the effects of COVID-19 pandemic on the diagnosis and treatment of colorectal cancer.

METHODS AND MATERIALS

A comprehensive search performed on June 2021 in various databases, including Medline, Web of Science, and Scopus. Keywords such as "diagnosis," "treatment," "coronavirus disease-19," "COVID-19," "coronavirus disease," "SARS-CoV-2 infection," "SARS-CoV-2," "2019-nCoV," "coronavirus, 2019 novel," "SARS-CoV-2 virus," severe acute respiratory syndrome coronavirus 2," "COVID-19," "COVID-19, coronavirus disease 19," "SARS coronavirus 2," "colorectal neoplasm," and "colorectal cancer " was used individually or a combination of these words. All retrieved articles were entered into a database on EndNote X7. Then, studies were first selected by title and then by abstract, and at the end, full texts were investigated.

RESULTS

Of the 850 studies, 43 were identified as eligible. According to studies, the diagnosis of colorectal cancer and the number of diagnostic procedures have decreased. Emergency visits due to obstruction or perforation of the large intestine or in advanced stages of cancer have increased, and a delay in the diagnosis of colorectal cancer has reported from 5.4 to 26%. Treatment of colorectal cancer has also decreased significantly or has been delayed, interrupted, or stopped. This reduction and delay have been observed in all treatments, including surgery, chemotherapy, and long-term radiation therapy; only cases of emergency surgery and short-term radiotherapy has increased. The waiting time for hospitalization and the length of hospital stay after surgery has been reported to be higher. Changes in patients' treatment plans and complete to partial cessation of hospitals activities-that provided treatment services-were reported.

CONCLUSION

According to the reduction in the diagnosis and treatment of colorectal cancer due to the COVID-19 pandemic, compensating for the reduction and preventing the continuation of this declining trend, requires serious and effective interventions to prevent its subsequent consequences, including referrals of people with advanced stages and emergency conditions, increasing treatment costs and reducing the quality of life and patients survival.

Assessment of the Versius Robotic Surgical System in Minimal Access Surgery: A Systematic Review

Background: Despite the superiority of minimal access surgery (MAS) over open surgery, MAS is difficult to perform and has a demanding learning curve. Robot-assisted surgery is an advanced form of MAS. The Versius® surgical robot system was developed with the aim of overcoming some of the challenges associated with existing surgical robots. The present study was designed to investigate the feasibility, clinical safety, and effectiveness of the Versius system in MAS. Materials and Methods: A comprehensive search was carried out in the Medline, Web of Science Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan), and Scopus databases for articles published until February 2022. The keywords used were Versius robot, visceral, colorectal, gynecology, and urologic surgeries. Articles on the use of the Versius robot in minimal access surgery (MAS) were included in the review. Results: Seventeen articles were reviewed for the study. The investigation comprised a total of 328 patients who had been operated on with this robot system, of which 48.3%, 14.2%, and 37.5% underwent colorectal, visceral, and gynecological procedures, respectively. Postoperative and major complications within 30 days varied from 7.4% to 39%. No major complications and no readmissions or reoperations were reported in visceral and gynecological surgeries. Readmission and reoperation rates in colorectal surgeries were 0–9%. Some procedures required conversion to conventional laparoscopic surgery (CLS) or open surgery, and all procedures were completed successfully. Based on the studies reviewed in the present report, we conclude that the Versius robot can be used safely and effectively in MAS. Conclusions: A review of the published literature revealed that the Versius system is safe and effective in minimal access surgery. However, the data should be viewed with caution until randomized controlled trials (RCTs) have been performed. Studies on the use of this robotic system in oncological surgery must include survival as one of the addressed outcomes.

Addressing the challenges restoring clinical services during the COVID-19 pandemic by harnessing the alignment of clinical and management leadership: an example from a large colorectal service

Background

The COVID-19 pandemic has posed the greatest operational challenge to the English National Health Service since its inception. Elective surgical services have struggled due to the need to protect both staff and patients from viral exposure, and perioperative COVID-19 infection has been associated with significant excess mortality.

Interventions

In this brief report, we describe how through necessity, it has provided an opportunity to redesign services for the benefit of both patients and organisations, with attendant improvement in activity compared with prepandemic metrics. We present the experience of a large district general hospital, using the department of colorectal surgery as a case study, in responding to the pandemic by restoring services and achieving improved short-term outcomes and processes in newly redesignated facilities.

Conclusions

These reorganised surgical services represent a ‘silver lining’ of the pandemic. Clinician-led service restructuring, with positive engagement with staff at all levels, has not only addressed backlogs of urgent elective patients in a safe environment, but has also led to patient benefits and high levels of patient and staff satisfaction.

Robotic Abdominal Surgery and COVID-19: A Systematic Review of Published Literature and Peer-Reviewed Guidelines during the SARS-CoV-2 Pandemic

Background: Significant concern emerged at the beginning of the SARS-CoV-2 pandemic regarding the safety and practicality of robotic-assisted surgery (RAS). We aimed to review reported surgical practice and peer-reviewed published review recommendations and guidelines relating to RAS during the pandemic. Methods: A systematic review was performed in keeping with PRISMA guidelines. This study was registered on Open Science Framework. Databases were searched using the following search terms: 'robotic surgery', 'robotics', 'COVID-19', and 'SARS-CoV-2'. Firstly, articles describing any outcome from or reference to robotic surgery during the COVID-19/SARS-CoV-2 pandemic were considered for inclusion. Guidelines or review articles that outlined recommendations were included if published in a peer-reviewed journal and incorporating direct reference to RAS practice during the pandemic. The ROBINS-I (Risk of Bias in Non-Randomised Studies of Intervention) tool was used to assess the quality of surgical practice articles and guidelines and recommendation publications were assessed using the AGREE-II reporting tool. Publication trends, median time from submission to acceptance were reported along with clinical outcomes and practice recommendations. Results: Twenty-nine articles were included: 15 reporting RAS practice and 14 comprising peer-reviewed guidelines or review recommendations related to RAS during the pandemic, with multiple specialities (i.e., urology, colorectal, digestive surgery, and general minimally invasive surgery) covered. Included articles were published April 2020-December 2021, and the median interval from first submission to acceptance was 92 days. All surgical practice studies scored 'low' or 'moderate' risk of bias on the ROBINS-I assessment. All guidelines and recommendations scored 'moderately well' on the AGREE-II assessment; however, all underperformed in the domain of public and patient involvement. Overall, there were no increases in perioperative complication rates or mortalities in patients who underwent RAS compared to that expected in non-COVID practice. RAS was deemed safe, with recommendations for mitigation of risk of viral transmission. Conclusions: Continuation of RAS was feasible and safe during the SARS-CoV-2 pandemic where resources permitted. Post-pandemic reflections upon published robotic data and publication patterns allows us to better prepare for future events and to enhance urgent guideline design processes.

Digital Technology-Based Telemedicine for the COVID-19 Pandemic

In the year 2020, the coronavirus disease 2019 (COVID-19) crisis intersected with the development and maturation of several digital technologies including the internet of things (IoT) with next-generation 5G networks, artificial intelligence (AI) that uses deep learning, big data analytics, and blockchain and robotic technology, which has resulted in an unprecedented opportunity for the progress of telemedicine. Digital technology-based telemedicine platform has currently been established in many countries, incorporated into clinical workflow with four modes, including "many to one" mode, "one to many" mode, "consultation" mode, and "practical operation" mode, and has shown to be feasible, effective, and efficient in sharing epidemiological data, enabling direct interactions among healthcare providers or patients across distance, minimizing the risk of disease infection, improving the quality of patient care, and preserving healthcare resources. In this state-of-the-art review, we gain insight into the potential benefits of demonstrating telemedicine in the context of a huge health crisis by summarizing the literature related to the use of digital technologies in telemedicine applications. We also outline several new strategies for supporting the use of telemedicine at scale.
