Feasibility of robotic radical hysterectomy (RRH) with a new robotic system. Experience at Galaxy Care Laparoscopy Institute

Initial experience with the Carina™ platform in robotic-assisted hysterectomy for gynecological malignant disease

OBJECTIVE

This retrospective study was performed to evaluate the efficiency and safety of a new modular robotic system, the Carina™ Platform (Ronovo Surgical, Shanghai, China), in gynecological surgery.

METHODS

All patients underwent robotic hysterectomies (RH) using the Carina performed by a single gynecologist experienced in laparoscopic and robotic surgery from November to December 2023. Patients were evaluated for estimated blood loss (EBL), intraoperative and postoperative complications, length of hospital stay, conversion rate, as well as console and docking times.

RESULTS

Two separate populations were involved: 10 cervical cancer patients (group 1) and six endometrial cancer patients (group 2). There were no conversions to laparotomies or laparoscopies. The mean docking time was 5.75 ± 2.38 min. The mean console time and mean operative time were 154.60 ± 26.01 min and 211.90 ± 53.65 min in group 1, respectively. The mean console time and mean operative time were 98.67 ± 26.71 min and 153.33 ± 22.77 min in group 2, respectively. The median estimated blood loss for group 1 and group 2 were 30 ml (20, 50) and 20 ml (7.5, 20), respectively. No intraoperative or postoperative complications related to the device were recorded.

CONCLUSION

Our experience allows us to state that the modular Carina Platform is safe and efficient in complex gynecologic surgery.

Feasibility evaluation of the Versius surgical system: robot-assisted hysterectomy for benign and malignant gynaecological lesions

INTRODUCTION

The application of minimally invasive surgery allows for radical and precise removal of the gynaecological lesion while simultaneously reducing the side effects and complications associated with surgical treatment. This paper aims to share our direct experience with the implementation of the CMR Versius robotic platform in the treatment of benign and malignant gynaecological lesions.

METHODS

This study included patients who underwent hysterectomy in the Department of Obstetrics, Gynaecology, and Gynaecologic Oncology at the Regional Polyclinical Hospital in Grudziadz, Poland. A total of 50 patients were included in the study: 29 underwent laparoscopic surgery and 21 underwent robot-assisted surgery using the CMR Versius system.

RESULTS

It was found that in the case of non-radical hysterectomy, the duration of surgery differed significantly (96.5 vs. 134.6 min, p < 0.01) in the groups of patients undergoing laparoscopic and robotic surgery. There were also no statistically significant differences in loss of blood parameters, rate of complications and conversions to other type of surgery after the laparoscopic and robotic surgeries. Both groups did not differ significantly in terms of hospitalisation time after surgery.

CONCLUSION

Versius CMR surgical robot assistance provides safe and effective support for MIS procedures in gynaecology.

Proposal of set-up standardization for general surgery procedures with the CMR Versius system, a new robotic platform: our initial experience

BACKGROUND

The article describes our initial experience using CMR Versius platform for several procedures in general surgery.

METHODS

Between September 2022 and April 2023, seventy patients underwent robotic surgery in a multi-robotic referral center (San Paolo University Hospital, Milan, Italy). Three surgeons with only laparoscopic experience performed 24 cholecystectomies, 13 inguinal hernia repairs, 9 ventral hernia repairs, 7 right hemicolectomies, 11 left hemicolectomies, 1 sigmoidectomy, 1 ileocecal resection, 1 ventral rectopexy, 1 Nissen fundoplication, 1 total splenectomy, and 1 exploration with multiple biopsies.

RESULTS

All surgeries were full-robotic, with only one conversion to laparoscopy. The short length of stay and low rate of severe morbidity are promising findings. Although operative time was lengthened, clinical outcomes were not affected.

CONCLUSIONS

Our experience demonstrates that the adoption of Versius system is safe and feasible in general surgery. The standardization of port placement and BSU set-up can certainly reduce the operative time.

Revolutionizing urology: the advancements and applications of robotic platforms

Robot-assisted surgery is developing as an acme of minimally invasive surgery, given its utmost dominance over laparoscopic surgery. The objective was to review the status of robotic surgery in urological practice with its advantages and disadvantages in current scenario. We conducted a literature search using MEDLINE and identified 72 articles which were relevant to urology. Single-port and various multiport robotic platforms like Da Vinci, Versius, Hugo RAS, Revo-I, Senhance, Mantra, Avatera, Hinotori, and MicroSurge are described with pros and cons. With a surge in different medical surgical robots purging into the market and a race to become the next standard of care in robotic surgery, it is only a matter of time when robotic surgery becomes financially comparable to laparoscopic surgeries.

The first robotic-assisted hysterectomy below the bikini line with the Dexter robotic system™

Background

Robotic-assisted hysterectomy (RAH) is a widely accepted minimally invasive approach for uterus removal. However, as RAH is typically performed in the umbilical region, it usually results in scars in cosmetically suboptimal locations. This is the first case of RAH with cervicosacropexy performed below the bikini line, using the new Dexter robotic system™.

Objectives

The aim of this article is to show the surgical steps of the first RAH with cervicosacropexy performed below the bikini line with the new Dexter robotic system™ (Distalmotion), and furthermore assess the feasibility of this approach using this robotic platform.

Materials and Methods

A 43-year-old woman with uterine adenomyosis and recurrent uterine prolapse underwent a robotic-assisted subtotal hysterectomy with cervicosacropexy, performed below the bikini line, using the Dexter robotic system™, at the Clinic of Gynecology and Obstetrics at Universitätsklinikum Schleswig-Holstein (UKHS) in Kiel, Germany.

Main outcome measures

Perioperative data, surgical approach specifics, objective, and subjective outcomes of this new approach.

Results

The procedure was performed without intra-operative complications; estimated blood loss was 10 ml. Operative time was 150 minutes, console time 120 minutes, total docking time 6 minutes. Dexter performed as expected; no device-related issues or robotic arm collisions occurred. The patient did not require pain medication and was released on the second postoperative day.

Conclusion

RAH performed below the bikini line using the Dexter robotic system™ is a feasible, safe, and adequate procedure. These initial results should be confirmed and further extensively refurbished with larger patient cohorts, and functional and psychological outcomes need further investigation.

Robotic Surgery in Urology: History from PROBOT® to HUGOTM

The advent of robotic surgical systems had a significant impact on every surgical area, especially urology, gynecology, and general and cardiac surgery. The aim of this article is to delineate robotic surgery, particularly focusing on its historical background, its evolution, its present status, and its future perspectives. A comprehensive literature review was conducted upon PubMed/MEDLINE, using the keywords "robotic surgical system", "robotic surgical device", "robotics AND urology". Additionally, the retrieved articles' reference lists were investigated. Analysis concentrated on urological surgical systems for laparoscopic surgery that have been given regulatory approval for use on humans. From the late 1980s, before daVinci® Era in 2000s, ancestor platform as Probot® and PUMA 560 were described to outline historical perspective. Thus, new robotic competitors of Intuitive Surgical such as Senhance®, Revo-I®, Versius®, Avatera®, Hinotori®, and HugoTM RAS were illustrated. Although daVinci® had high level competitiveness, and for many years represented the most plausible option for robotic procedures, several modern platforms are emerging in the surgical market. Growing competition through unique features of the new robotic technologies might extend applications fields, improve diffusion, and increase cost-effectiveness procedures. More experiences are needed to identify the role of these new advancements in surgical branches and in healthcare systems.

Evaluation of the Versius Robotic System for Infant Surgery-A Study in Piglets of Less than 10 kg Body Weight

BACKGROUND

We were able to demonstrate the feasibility of a new robotic system (Versius, CMR Surgical, Cambridge, UK) for procedures in small inanimate cavities. The aim of this consecutive study was to test the Versius^® system for its feasibility, performance, and safety of robotic abdominal and thoracic surgery in piglets simulating infants with a body weight lower than 10 kg.

METHODS

A total of 24 procedures (from explorative laparoscopy to thoracoscopic esophageal repair) were performed in 4 piglets with a mean age of 12 days and a mean body weight of 6.4 (7-7.5) kg. Additional urological procedures were performed after euthanasia of the piglet. The Versius^® robotic system was used with 5 mm wristed instruments and a 10 mm 3D 0° or 30° camera. The setup consisted of the master console and three to four separate arms. The performance of the procedure, the size, position, and the distance between the ports, the external and internal collisions, and complications of the procedures were recorded and analyzed.

RESULTS

We were able to perform all surgical procedures as planned. We encountered neither surgical nor robot-associated complications in the live model. Whereas all abdominal procedures could be performed successfully under general anesthesia, one piglet was euthanized early before the thoracic interventions, likely due to pulmonary inflammatory response. Technical limitations were based on the size of the camera (10 mm) being too large and the minimal insertion depth of the instruments for calibration of the fulcrum point.

CONCLUSIONS

Robotic surgery on newborns and infants appears technically feasible with the Versius^® system. Software adjustments for fulcrum point calibration need to be implemented by the manufacturer as a result of our study. To further evaluate the Versius^® system, prospective trials are needed, comparing it to open and laparoscopic surgery as well as to other robotic systems.

Comparison of the Oncological Outcomes Between Robot-Assisted and Abdominal Radical Hysterectomy for Cervical Cancer Based on the New FIGO 2018 Staging System: A Multicentre Retrospective Study

Objective

To compare the 3-year oncological outcomes of robot-assisted radical hysterectomy (RRH) and abdominal radical hysterectomy (ARH) for cervical cancer.

Methods

Based on the clinical diagnosis and treatment for cervical cancer in the China database, patients with FIGO 2018 stage IA with lymphovascular space invasion (LVSI)-IB2 cervical cancer disease who underwent RRH and ARH from 2004 to 2018 were included. Kaplan–Meier survival analysis was used to compare the 3-year overall survival (OS) and disease-free survival (DFS) rate between patients receiving RRH and those receiving ARH. The Cox proportional hazards model and propensity score matching were used to estimate the surgical approach-specific survival.

Results

A total of 1,137 patients with cervical cancer were enrolled in this study, including the RRH group (n = 468) and the ARH group (n = 669). The median follow-up time was 45 months (RRH group vs. ARH group: 24 vs. 60 months). Among the overall study population, there was no significant difference in 3-year OS and DFS between the RRH group and the ARH group (OS: 95.8% vs. 97.6% p = 0.244). The Cox proportional hazards analysis showed that RRH was not an independent risk factor for 3-year OS (HR: 1.394, 95% CI: 0.552–3.523, p = 0.482). However, RRH was an independent risk factor for 3-year DFS (HR: 1.985, 95% CI: 1.078–3.655 p = 0.028). After 1:1 propensity score matching, there was no significant difference in 3-year OS between the RRH group and the ARH group (96.6% vs. 98.0%, p = 0.470); however, the 3-year DFS of the RRH group was lower than that of the ARH group (91.0% vs. 96.1%, p = 0.025). The Cox proportional hazards analysis revealed that RRH was not an independent risk factor for 3-year OS (HR: 1.622, 95% CI: 0.449–5.860 p = 0.461), but RRH was an independent risk factor for 3-year DFS (HR: 2.498, 95% CI: 1.123–5.557 p = 0.025).

Conclusion

Among patients with stage I A1 (LVSI +)-I B2 cervical cancer based on the FIGO 2018 staging system, RRH has a lower 3-year DFS than ARH, suggesting that RRH may not be suitable for early cervical cancer patients.

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.

Transition from da Vinci to Versius robotic surgical system: initial experience and outcomes of over 100 consecutive procedures

We sought to describe the development of the robotic urology program at Sindh Institute of Urology and Transplantation (SIUT) and the feasibility of transitioning from the da Vinci to Versius robotic systems. The SIUT robotics program began in 2017 utilizing the da Vinci Si robotic system, transitioning to the Versius system in 2021. Retrospective review of our quality assurance database was performed. All procedures performed utilizing the two systems were identified, analyzed, and compared. Data were described with descriptive statistics. Matched procedures (by type of procedure) performed by the same surgeons utilizing the da Vinci and Versius were compared. All tests were double-sided with statistical significance set at p < 0.05.106 cases were performed by the Versius robotic surgical system in 2021. Median age was 42 years (IQR 26-56), and 69 (65%) were males. Procedures included both benign (83%) and malignant disorders (17%), several upper tract (75%), and pelvic/lower tract (25%). No major intraoperative complications were observed. Conversion to open occurred in six procedures. Malfunction of the robotic arms occurred in two procedures: the erroneous bedside units (BSU) were replaced. Eight patients developed postoperative high-grade complications. Matched analysis of various procedures (pyeloplasty, stone surgery, radical, partial, and simple nephrectomy) showed no significant difference in perioperative outcomes. To our knowledge, this is the first and largest series of urologic procedures performed by the Versius robotic surgical system.

Initiation and feasibility of a multi-specialty minimally invasive surgical programme using a novel robotic system: A case series

INTRODUCTION

There are a number of small case series examining new robotic surgical systems, but this is the first large case series assessing the feasibility of the Versius® system from CMR Surgical (1 Evolution Business Park, Cambridge, UK) in a multi-specialty setting.

MATERIALS AND METHODS

All patients undergoing Versius®-assisted surgery in a previously robot-naïve centre were consented for collection of data on demographics, pre-, intra-, and postoperative outcomes. Data collection was performed prospectively from the start of the robotic surgical programme.

RESULTS

160 operations were performed over a 19-month period, including 68 colorectal, 60 gynaecology, and 32 general surgery cases. The conversion rate to open surgery was 4.4% for colorectal, and 0% for gynaecology and general surgery. Median length of stay was 6 days for colorectal, 1 day for gynaecology, and 0 days for general surgery. Other outcomes were comparable to existing literature for robotic assisted surgery.

CONCLUSION

The Versius® system is safe and feasible for use in a multi-specialty minimally invasive surgery programme, including colorectal, general surgical & gynaecological cases, and operative volume can be safely and easily scaled up in a district general hospital setting without prior robotic surgical experience.

Robotic surgical systems in urology: What is currently available?

Robotic assistance in laparoscopic surgery was introduced at the turn of this millennium, marking a milestone in the history of surgery. Urologists were early adopters of robotic technology and the indications of robot-assisted surgery in urology are expanding. Over the last 20 years, the da Vinci surgical system was the dominant system in the robotic surgical market. However, the recent expiration of Intuitive patents has allowed new systems to enter the market more freely. We performed a nonsystematic literature review using the PubMed/MEDLINE search engines. The aim of this review was to briefly summarize the currently available robotic surgical systems for laparoscopic urologic surgery. New surgical devices have already been launched in the robotic market and the da Vinci systems have some competition. The innovation of robotic technology is continuing, and new features such as an open-console design, haptic feedback, smaller instruments, and separately mounted robotic arms have been introduced. A new robotic era is rising, and new systems and technologies enhancing patient care are welcomed.

Advances and Trends in Pediatric Minimally Invasive Surgery

As many meta-analyses comparing pediatric minimally invasive to open surgery can be found in the literature, the aim of this review is to summarize the current state of minimally invasive pediatric surgery and specifically focus on the trends and developments which we expect in the upcoming years. Print and electronic databases were systematically searched for specific keywords, and cross-link searches with references found in the literature were added. Full-text articles were obtained, and eligibility criteria were applied independently. Pediatric minimally invasive surgery is a wide field, ranging from minimally invasive fetal surgery over microlaparoscopy in newborns to robotic surgery in adolescents. New techniques and devices, like natural orifice transluminal endoscopic surgery (NOTES), single-incision and endoscopic surgery, as well as the artificial uterus as a backup for surgery in preterm fetuses, all contribute to the development of less invasive procedures for children. In spite of all promising technical developments which will definitely change the way pediatric surgeons will perform minimally invasive procedures in the upcoming years, one must bear in mind that only hard data of prospective randomized controlled and double-blind trials can validate whether these techniques and devices really improve the surgical outcome of our patients.
