Telesurgery has been recently gaining momentum as a natural evolution of robotic surgery. Besides providing expert surgical care to patients who cannot geographically access it, telesurgery can also facilitate surgical collaboration between surgeons who might need urgent assistance or coaching experts. The idea of having two consoles, with one remote and one local, has been the ideal setup for such ecosystems. However collaborations can take on many forms and might require more than one remote surgeon, depending on procedure complexity and surgeon availability. The objective of the study was to describe our perspectives and experience performing telesurgery on one patient, using three surgeon consoles for three surgeons, operating from three separate cities. In November 2023, a triple-console, robot-assisted radical prostatectomy (RARP) was performed in a collaborative effort among three surgeons in three separate locations employing telesurgery using the Kangduo Endosopic Surgical Robot (KD-SR-01, Sagebot Medical). The furthest distance between participants was approximately 2600 km between Beijing and Hainan. We described and illustrated the applications and outcomes of this procedure to treat a single patient with prostate cancer. The local surgeon, along with the operating room team, and the patient were in Hainan, while the other two surgeons were in Beijing and Hunan Telesurgery command centers. The procedure lasted approximately 120 min and there were no intra- or postoperative complications. Estimated blood loss was 100 ml. The patient was ambulating 4 h after surgery and remained in the hospital for 2 days secondary to the postoperative care protocol followed by the local team taking care of the patient. The Foley catheter was removed on postoperative day 7 without complication. The final pathology was ISUP Grade Group 4 (Gleason score 4 + 4 = 8) T2cN0 with negative surgical margins. Our experience shows that telesurgery involving multiple surgeons at multiple remote locations is possible and can be completed safely with low-latency connections via available telecommunication networks.

Background:  Robotic metabolic and bariatric surgery (RMBS) has emerged as an innovative approach in the treatment of severe obesity by combining the ergonomic precision of robotic technology and instrumentation with the established benefits of weight loss surgery. This study employs a bibliometric approach to identify local research trends and worldwide patterns in RMBS.

Materials & methods:  The research methodology used "robotic" and "metabolic" or "bariatric surgery" to search Web of Science. Articles that were published prior to December 31st, 2023, were included. The analyses were developed using the Rayyan and Bibliometric, in R Studio.

Results:  265 articles from 51 different journals were included. Scientific production of RMBS experienced a significant annual growth rate of 21.96% from 2003 to 2023, resulting in an average of 12.6 papers published per year. A high correlation (R2 = 0.94) was found between the year and number of articles. The mean number of citations per document was 13.25. Approximately 90% of the journals were classified as zone 3, according to the Bradford categorization. International collaboration was identified in 10.57% of cases, with the University of California and the University of Illinois being the most common organizations. The countries with the highest number of corresponding authors, in descending order, were the United States of America, China, and Switzerland.

Conclusion:  Scientific production in RMBS has experienced sustained growth since the first original publications in 2003. While it has not yet reached the volume, impact, and international collaboration seen in studies related to non-robotic metabolic and bariatric surgery, RBMS holds potential that remains to be explored.

Introduction: Obesity is a global health issue that significantly increases morbidity and mortality when the Body Mass Index (BMI) reaches values ≥ 50. While metabolic and bariatric surgery (MBS) is the most effective treatment for severe obesity, it carries risks. Robotic surgery is promising but not extensively studied in Mexico, which presents an opportunity for research at a National Hospital with an academic program.

Methods: This retrospective study reviewed 44 patients who underwent robotic MBS using the da Vinci surgical system from January 2018 to August 2023 at Centro Médico Nacional 20 de Noviembre, ISSSTE. Data collected included surgery type, duration, complications, and weight loss metrics over 54 months post-operatively.

Results: The study involved 44 patients with severe obesity including BMI ≥ 50-59.9 kg/m² for group 1 and BMI ≥ 60 kg/m² for group 2. The average initial BMI was 54.7 kg/m² for group 1 and 68 kg/m² for group 2. The average operative times for group 1 were 10.09 min for docking, 86.23 min for robotic console time, and 95.73 min for total intraoperative time. Group 2 had average times of 9.80 min for docking, 82.4 min for robotic console time, and 92.2 min for total intraoperative time. Follow-up showed significant weight loss initially, with weight recurrence after 24 months due to different factors. No serious complications or mortality were observed.

Conclusion: Robotic MBS at a national academic medical center in Mexico shows promising outcomes for patients with BMI ≥ 50-59.9 and BMI ≥ 60, with significant weight and BMI improvements at 54 month follow-up. Further studies with larger cohorts and longer follow-up are needed to strengthen these findings.

Robotic-assisted surgery has revolutionised minimally invasive approaches, particularly in colorectal surgery. While many single-center studies on colorectal surgeries exist in present literature, including experiences with Senhance® Robotic Systems, comprehensive multi-center studies are lacking. This study, conducted through the TransEnterix European Patient Registry ("TRUST"), aims to assess the safety and feasibility in this context. The present study explored procedural times, complications, robotic malfunction and limitations, adverse events and pain management outcomes for colorectal procedures, including sigmoid resection, right hemicolectomy and rectal surgery collected in two European centers. Data from 355 colorectal surgeries showed that the median duration of surgery was 147.2 min (IQR: 124.3-183.0), the docking time was reported with a median of 3.4 min (IQR: 2.0-5.4) and the console time was found at a mean of 84.4 min (SD: 33.6). Despite minimal blood loss, pain scores, and robotic malfunction, 2.9% of the cases (10 instances) required conversions to either an open or laparoscopic approach. Further, most robotic limitations were attributed to limited motion (18.9%, 67 cases) and collisions (11.5%, 41 cases). Adverse events (24 cases, 6.8%) were effectively managed, with 23 instances judged completely unrelated to the robotic system. This study underscores the positive outcomes and safety profile of Senhance® Robotic Systems in colorectal surgery, contributing valuable insights for future research and clinical practice.

Evaluating the risk factors for the conversion from robotic-assisted partial nephrectomy (RAPN) to radical nephrectomy (RN). Through a comprehensive database search encompassing PubMed, Web of Science, Embase, and the Cochrane Library, we identified pertinent English-language research published by June 2024. We utilized the NOS scale for quality assessment. The aggregate effect was quantified via the odds ratio (OR), alongside a 95% confidence interval (CI). Sensitivity analyses were conducted using both fixed-effects and random-effects models to evaluate reliability. The meta-analytical process was facilitated by the Stata 18 software suite. Our meta-analysis encompassed a total of 8 retrospective studies and 3 prospective studies, totaling 4056 patients. We found that increasing patient age (OR: 1.04; 95% CI 1.00-1.08; P = 0.005), higher American Society of Anesthesiologists (ASA) scores (3 or above) (OR: 2.74; 95% CI 1.52-4.93; P = 0.001), elevated R.E.N.A.L. scores (7 or above) (OR: 2.49; 95% CI 1.57-3.95; P < 0.001), and the use of off-clamp RAPN (OR: 7.21; 95% CI 2.60-19.93; P < 0.001) significantly raised the odds of surgical conversion. On the other hand, male sex (OR: 1.04; 95% CI 0.67-1.62; P = 0.858), the side of the tumor (OR: 0.97; 95% CI 0.48-1.95; P = 0.936), tumor size (OR: 3.43; 95% CI 0.57-20.55; P = 0.177), body mass index (BMI) (OR: 1.03; 95% CI 0.96-1.11; P = 0.426), clinical stage (OR: 3.78; 95% CI 0.46-30.70; P = 0.214), and the use of single-port RAPN (OR: 0.54; 95% CI 0.16-1.78; P = 0.31) did not show a statistically significant link to an increased conversion risk. This meta-analysis elucidates the critical risk factors for the conversion from robotic-assisted partial nephrectomy to radical nephrectomy, providing significant guidance for preoperative risk assessment and clinical decision-making. However, our findings necessitate validation through studies with larger sample sizes.

Midline incision for extra-corporeal anastomosis is common with traditional laparoscopic right hemicolectomy. Incisional hernias develop in up to 20% of these patients within a year adding considerable morbidity and healthcare costs. Robotic assisted surgery (RAS) improves technical ease of intra-corporeal anastomosis, preventing midline extraction but its benefit over laparoscopy remains debated. We aimed to determine if robotic assisted surgery and Pfannenstiel extraction decreased the rate of radiologically detected incisional hernias compared to standard laparoscopy with extra-corporeal anastomosis. The secondary outcomes aimed to evaluate incidence of port site hernias in 8 mm robotic ports for which routine closure is not followed. Our single centre retrospective cohort study included patients who had minimally invasive right hemicolectomy and had cross-sectional imaging at least 1-year later. Patient demographics, body mass index, history of smoking or previous surgery was recorded. At imaging, evidence of new extraction site or port site-site hernia, contents and clinical impact was noted. A total of 100 patients (50 robotic and 50 laparoscopic) were included. Baseline characteristics appeared equally distributed. 16% (8 patients) who had laparoscopic surgery developed midline extraction site hernias which was significantly higher to RAS group (0 patients). 3 patients developed hernias at the site of robotic ports and this was more commonly at the right iliac fossa port. RAS, by simplifying intra-corporeal anastomosis has potential to eliminate incisional hernias, particularly when Pfannenstiel extraction is used. The potential for 8 mm robotic ports to develop clinically significant hernias cannot be ignored and meticulous closure can prevent patient harm.

Robot-assisted laparoscopic surgery has three main system requirements: safety, simplicity, and intuitiveness. However, accidental movement of the endoscope due to body fatigue and misunderstanding of the verbal orders between the surgeon and assistant will contribute to highly unexpected tool-tissue interactions, particularly in pediatric minimal access surgery with restricted working space. This study introduces a compact, lightweight endoscope manipulator with a mechanical remote-center-motion function. Using a custom-designed human-machine interface, the surgeon can intuitively control the movement of the endoscope manipulator over their view. In addition, an active constrained motion control algorithm is proposed to generate a forbidden-region constraint for avoiding collisions between the endoscope tip and surrounding organs in a pediatric abdominal cavity with restricted space. Simulations and experiments demonstrate the performance of the proposed compact endoscope manipulator and the active constrained surface tracking control scheme.

A comparison was conducted between robot-assisted radical prostatectomy (RARP) performed using the Hugo RAS System and the Da Vinci System. We conducted an extensive search of online databases through September 2024. The data from eligible studies were pooled and analyzed with Review Manager 5.4, employing a random effects model. Weighted mean difference (WMD) and odds ratios (OR) with 95% confidence intervals (CI) were used to analyze continuous and categorical variables. A total of eight original studies, involving 1155 patients (HUGO-RARP: 468 vs. da Vinci-RARP: 687), were included. Compared with da Vinci-RARP, HUGO-RARP had a longer docking time (WMD: 6.2 min; 95% CI 4.25-8.14; p < 0.0001), while no significant differences were observed in total operative time, console time, bladder neck dissection time, seminal vesicle dissection time, vesicourethral anastomosis time, or pelvic lymph node dissection time between two systems. There were no significant differences in hospital stay, estimated blood loss, catheter duration, or complication rates. Likewise, oncological and functional outcomes were similar between the two systems. While these results suggest that the Hugo RAS system performs as well as the Da Vinci system in RARP, more randomized controlled studies are needed to further evaluate prognostic outcomes.

The purpose of this study and meta-analysis was to evaluate the perioperative and oncologic results of robotic NOSE versus laparoscopic surgery for colorectal tumors. We plan to perform an extensive electronic search on PubMed, CNKI, Embase, and the Cochrane Library to find research articles published from the beginning of the databases until July 2024 that examine the comparison between robotic natural orifice specimen extraction and laparoscopic surgery in patients with colorectal cancer. Both English and Chinese literature will be included. Literature screening will strictly follow predetermined criteria for inclusion and exclusion, specifically targeting randomized controlled trials and cohort studies. The evaluation of quality will be conducted with the Newcastle-Ottawa Scale (NOS). Review Manager 5.4.1 will be utilized to perform a meta-analysis of data gathered from the studies that are included. The ultimate evaluation included seven past cohort studies with a total of 1117 participants (545 who had robotic NOSE and 572 who had laparoscopic surgery). Patients who had robotic NOSE experienced notable enhancements in LOHS, time to first flatus, time to start the liquid diet, EBL, and postoperative ileus when compared to patients undergoing laparoscopic colorectal surgery. There were no notable discrepancies noted in terms of surgical duration, total complications, lymph node collection, and anastomotic leakage between the two methods. In conclusion, the use of robotic technology for extracting specimens through natural body openings in colorectal surgery is considered to be safe and achievable. It offers notable advantages over laparoscopic surgery, including reduced hospital stay, earlier time to first flatus and liquid intake, decreased EBL, and lower incidence of postoperative ileus.
