Abstract
Background and objective Robot-assisted radical prostatectomy (RARP) is widely used because of the many advantages of a robotic approach. The da Vinci Si robot is one of the most commonly used surgical robot systems, but it may be associated with higher costs owing to the use of consumable surgical supplies. Our aim was to conduct a preliminary investigation of the capability of the MP1000 system for RARP. Methods In this prospective, multicentre, single-blinded study, we randomly assigned 42 patients scheduled to undergo RARP between April and September 2021 to a da Vinci Si group (control) or an MP1000 group (intervention). Patients underwent RARP performed using the assigned robotic system and were followed up at 3-mo intervals. The primary outcome was the rate of conversion to open/laparoscopic surgery. Secondary outcomes were installation and operation times, intraoperative blood loss, postoperative surgical margin status, hospital stay, incontinence, complications, safety indicators, and surgeon ergonomics. Key findings and limitations All procedures were successfully completed without conversion to open/laparascopic surgery or major complications. Secondary outcomes, including oncological and ergonomic indicators, did not differ significantly between the groups over the study period. One patient in the control group experienced dysuria (Clavien-Dindo grade 3). No patients had incontinence at 3 mo. A limitation of the study is the small sample size. Conclusions and clinical implications RARP with the MP1000 system is feasible, safe, and effective in the management of localised prostate cancer. Patient summary We assessed the effectiveness and safety of the new MP1000 robot system for robot-assisted removal of the prostate in comparison to the da Vinci Si robot. We found no difference in effectiveness or safety among 42 patients with prostate cancer who were assigned randomly to one of the two systems. We conclude that the MP1000 is a suitable robot for this surgery.

Abstract
Robot-assisted surgery platforms are utilized globally thanks to their stereoscopic vision systems and enhanced functional assistance. However, the necessity of ergonomic improvement for their use by surgeons has been increased. In surgical robots, issues with chronic fatigue exist owing to the fixed posture of the conventional stereo viewer (SV) vision system. A head-mounted display was adopted to alleviate the inconvenience, and a virtual vision platform (VVP) is proposed in this study. The VVP can provide various critical data, including medical images, vital signs, and patient records, in three-dimensional virtual reality space so that users can access medical information simultaneously. An availability of the VVP was investigated based on various user evaluations by surgeons and novices, who executed the given tasks and answered questionnaires. The performances of the SV and VVP were not significantly different; however, the craniovertebral angle of the VVP was 16.35° higher on average than that of the SV. Survey results regarding the VVP were positive; participants indicated that the optimal number of displays was six, preferring the 2 × 3 array. Reflecting the tendencies, the VVP can be a neoconceptual candidate to be customized for medical use, which opens a new prospect in a next-generation surgical robot.

Abstract
PURPOSE Open ureteral reimplantation is considered the standard surgical approach to treat distal ureteral strictures or injuries. These procedures are increasingly performed in a minimally invasive and robotic-assisted manner. Notably, no series comparing perioperative outcomes and safety of the open vs. robotic approach are available so far. METHODS In this retrospective multi-center study, we compared data from 51 robotic ureteral reimplantations (RUR) with 79 open ureteral reimplantations (OUR). Both cohorts were comparatively assessed using different baseline characteristics and perioperative outcomes. Moreover, a multivariate logistic regression for independent predictors was performed. RESULTS Surgery time, length of hospital stay and dwell time of bladder catheter were shorter in the robotic cohort, whereas estimated blood loss, postoperative blood transfusion rate and postoperative complications were lower than in the open cohort. In the multivariate linear regression analysis, robotic approach was an independent predictor for a shorter operation time (coefficient - 0.254, 95% confidence interval [CI] - 0.342 to - 0.166; p < 0.001), a lower estimated blood loss (coefficient - 0.390, 95% CI - 0.549 to - 0.231, p < 0.001) and a shorter length of hospital stay (coefficient - 0.455, 95% CI - 0.552 to - 0.358, p < 0.001). Moreover, robotic surgery was an independent predictor for a shorter dwell time of bladder catheter (coefficient - 0.210, 95% CI - 0.278 to - 0.142, p < 0.001). CONCLUSION RUR represents a safe alternative to OUR, with a shorter operative time, decreased blood loss and length of hospital stay. Prospective research are needed to further define the extent of the advantages of the robotic approach over open surgery.

Abstract
Robotic-assisted radical prostatectomy (RARP) has become the leading approach for radical prostatectomy driven by innovations aimed at improving functional and oncological outcomes. The initial advancement in this field was transperitoneal multiport robotics, which has since undergone numerous technical modifications. These enhancements include the development of extraperitoneal, transperineal, and transvesical approaches to radical prostatectomy, greatly facilitated by the advent of the Single Port (SP) robot. This review offers a comprehensive analysis of these evolving techniques and their impact on RARP. Additionally, we explore the transformative role of artificial intelligence (AI) in digitizing robotic prostatectomy. AI advancements, particularly in automated surgical video analysis using computer vision technology, are unprecedented in their scope. These developments hold the potential to revolutionize surgeon feedback and assessment and transform surgical documentation, and they could lay the groundwork for real-time AI decision support during surgical procedures in the future. Furthermore, we discuss future robotic platforms and their potential to further enhance the field of RARP. Overall, the field of minimally invasive radical prostatectomy for prostate cancer has been an incubator of innovation over the last two decades. This review focuses on some recent developments in robotic prostatectomy, provides an overview of the next frontier in AI innovation during prostate cancer surgery, and highlights novel robotic platforms that may play an increasing role in prostate cancer surgery in the future.

Abstract
Purpose: To evaluate the feasibility and intraoperative technical parameters of the new robot-assisted surgical system Avatera by performing bilateral nephrectomy in a live porcine model. Materials and Methods: Six pigs underwent bilateral robot-assisted radical nephrectomy using the Avatera robotic system (RS). The operations were performed by experienced open (Group 1) and laparoscopic (Group 2) surgeons. The operating time, docking time, set-up time, and console time were evaluated. Data regarding intraoperative complications (major or not), injury of adjacent organs, and technical difficulties during the operation were also recorded. Results: Robot-assisted bilateral nephrectomy was completed effectively in all sample pigs. The docking time and set-up time were similar among the two groups, whereas the console time and operating time were significantly longer for the open surgeon group. Two intraoperative minor complications occurred in the open surgeon's group. An inadvertent damage of the renal vein occurred in two cases and the bleeding was controlled effectively. Other than the initial two cases, the estimated blood loss was <50 mL in both groups. Injury of the adjacent organs was not noticed. Conclusions: The study demonstrated that radical nephrectomy using the Avatera robotic surgical system is technically feasible, safe, and valid in pigs. Our results warrant the application of the Avatera RS in other urologic procedures, collecting data for further clinical trials.

Abstract
Importance Many health care systems publish hospital-level quality measures as a driver of hospital performance and to support patient choice, but it is not known if patients with cancer respond to them. Objective To investigate hospital quality and patient factors associated with treatment location. Design, Setting, and Participants This choice modeling study used national administrative hospital data. Patients with colon and rectal cancer treated in all 163 English National Health Service (NHS) hospitals delivering colorectal cancer surgery between April 2016 and March 2019 were included. The extent to which patients chose to bypass their nearest surgery center was investigated, and conditional logistic regression was used to estimate the association of additional travel time, hospital quality measures, and patient characteristics with treatment location. Exposures Additional travel time in minutes, hospital characteristics, and patient characteristics: age, sex, cancer T stage, socioeconomic status, comorbidity, and rural or urban residence. Main Outcomes and Measures Treatment location. Results Overall, 44 299 patients were included in the final cohort (mean [SD] age, 68.9 [11.6] years; 18 829 [42.5%] female). A total of 8550 of 31 258 patients with colon cancer (27.4%) and 3933 of 13 041 patients with rectal cancer (30.2%) bypassed their nearest surgical center. Travel time was strongly associated with treatment location. The association was less strong for younger, more affluent patients and those from rural areas. For rectal cancer, patients were more likely to travel to a hospital designated as a specialist colorectal cancer surgery center (odds ratio, 1.45; 95% CI, 1.13-1.87; P = .004) and to a hospital performing robotic surgery for rectal cancer (odds ratio, 1.43; 95% CI, 1.11-1.86; P = .007). Patients were less likely to travel to hospitals deemed to have inadequate care by the national quality regulator (odds ratio, 0.70; 95% CI, 0.50-0.97; P = .03). Patients were not more likely to travel to hospitals with better 2-year bowel cancer mortality outcomes. Conclusions and Relevance Patients appear responsive to hospital characteristics that reflect overall hospital quality and the availability of robotic surgery but not to specific disease-related outcome measures. Policies allowing patients to choose where they have colorectal cancer surgery may not result in better outcomes but could drive inequities in the health care system.

Abstract
PURPOSE To evaluate the potential opportunities and possible competitiveness of Avatera robotic system (ARS) (Avateramedical, Germany), and perform predictive cost-analysis for its implementation and dissemination. MATERIAL AND METHODS Our study employed a projective quantitative research design. SWOT (strengths, weaknesses, opportunities, threats) analysis was used to map ARS internal competencies towards external contexts, and potential opportunities and risks in the robotic market. The ARS purchase and procedural costs were evaluated in two different scenarios. RESULTS In the first scenario, setting the purchase cost of the Avatera at around $1.3-1.5 million, a total $400 procedural cost reduction compared to the RAS performed with the da Vinci Xi can be calculated. In the second scenario, with a purchase cos of the ARS of $700.000-800.000 and considering a 5-year period with an annual ARS volume of 500 procedures, only an additional $300 will be attributed to the robot itself. Our projections revealed that for an effective competition the purchase cost of ARS should range between $700.000 and $800.000 during the initial phase of market entry. The marketing strategy of the ARS should be oriented towards countries without any robotic system in operational use, followed by countries where the competition intensity in the marketplace is low. CONCLUSION The introduction of new robotic systems will greatly affect and reshape the market of robotic surgery. The ARS has all the technical capacity ensuring the performance of high-quality surgical procedures. A fast spread and implementation of the ARS could be expected should the purchase and maintenance costs be kept low.

Robot-assisted simple prostatectomy versus open simple prostatectomy: a single-center comparison. World J Urol 2020; 39:149-156. [PMID: 32222811 PMCID: PMC7858208 DOI: 10.1007/s00345-020-03168-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2019] [Accepted: 03/13/2020] [Indexed: 02/07/2023] Open
Abstract
Purpose Open simple prostatectomy (OSP) is a standard surgical technique for patients with benign prostatic hyperplasia with prostate size larger than 80 ml. As a minimally invasive approach, robot-assisted simple prostatectomy (RASP) emerged as a feasible surgical alternative. Currently, there are no definite recommendations for the standard use of RASP. Therefore, we aimed at investigating various clinical outcomes comparing RASP with OSP. Methods In this retrospective single-center study, we evaluated clinical data from 103 RASP and 31 OSP patients. Both cohorts were compared regarding different clinical characteristics with and without propensity score matching. To detect independent predictive factors for clinical outcomes, multivariate logistic regression analysis was performed. Results Robot-assisted simple prostatectomy patients demonstrated a lower estimated blood loss and need for postoperative blood transfusions as well as less postoperative complications. OSP had a shorter operative time (125 min vs. 182 min) longer hospital stay (11 days vs. 9 days) and longer time to catheter removal (8 days vs. 6 days). In the multivariate analysis, RASP was identified as an independent predictor for longer operative time, lower estimated blood loss, shorter length of hospital stay, shorter time to catheter removal, less postoperative complications and blood transfusions. Conclusion Robot-assisted simple prostatectomy is a safe alternative to OSP with less perioperative and postoperative morbidity. Whether OSP (shorter operative time) or RASP (shorter length of hospital stay) has a more favorable economic impact depends on the particular conditions of different health care systems. Further prospective comparative research is warranted to define the value of RASP in the current surgical management of benign prostatic hyperplasia.

Considering the role of radical prostatectomy in 21st century prostate cancer care. Nat Rev Urol 2020; 17:177-188. [PMID: 32086498 DOI: 10.1038/s41585-020-0287-y] [Citation(s) in RCA: 71] [Impact Index Per Article: 17.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/20/2020] [Indexed: 12/16/2022]
Abstract
The practice of radical prostatectomy for treating prostate cancer has evolved remarkably since its general introduction around 1900. Initially described using a perineal approach, the procedure was later popularized using a retropubic one, after it was first described as such in 1948. The open surgical method has now largely been abandoned in favour of the minimally invasive robot-assisted method, which was first described in 2000. Until 1980, the procedure was hazardous, often accompanied by massive blood loss and poor outcomes. For patients in whom surgery is indicated, prostatectomy is increasingly being used as the first step in a multitherapeutic approach in advanced local, and even early metastatic, disease. However, contemporary molecular insights have enabled many men to safely avoid surgical intervention when the disease is phenotypically indolent and use of active surveillance programmes continues to expand worldwide. In 2020, surgery is not recommended in those men with low-grade, low-volume Gleason 6 prostate cancer; previously these men - a large cohort of ~40% of men with newly diagnosed prostate cancer - were offered surgery in large numbers, with little clinical benefit and considerable adverse effects. Radical prostatectomy is appropriate for men with intermediate-risk and high-risk disease (Gleason score 7-9 or Grade Groups 2-5) in whom radical prostatectomy prevents further metastatic seeding of potentially lethal clones of prostate cancer cells. Small series have suggested that it might be appropriate to offer radical prostatectomy to men presenting with small metastatic burden (nodal and or bone) as part of a multimodal therapeutic approach. Furthermore, surgical treatment of prostate cancer has been reported in cohorts of octogenarian men in good health with minimal comorbidities, when 20 years ago such men were rarely treated surgically even when diagnosed with localized high-risk disease. As medical therapies for prostate cancer continue to increase, the use of surgery might seem to be less relevant; however, the changing demographics of prostate cancer means that radical prostatectomy remains an important and useful option in many men, with a changing indication.

Abstract
This article investigates qualitatively the value profile of the da Vinci® surgical robot after almost two decades of extensive clinical use and research. We aimed to understand whether the swiftly growing body of published studies on robotic prostate surgery can now, that is, beyond an early stage, guide decisions on the acquisition, procurement, and public provision of this innovation. We explored both published studies and the perspectives of diverse stakeholders in the Netherlands. Both arenas represent conflicting, often polarised arguments on the (added) value of da Vinci surgery. What was unclear a decade ago due to lack of evidence is now unclear because of controversies about evidence. The article outlines controversial value issues and indicates the unlikelihood that awaiting more research - amid the mantra "further studies are needed" - will resolve the controversy. The study underscores multi-stakeholder deliberation to resolve controversies regarding the value of advanced medical innovations.

Abstract
OBJECTIVES To quantify public and academic interest in the urological field using a novel new media-based methodology. METHODS We systematically measured public and academic interest in 56 urological keywords and combined in nine subspecialties. Public interest was quantified as video views on YouTube. Academic interest was quantified as article citations using Microsoft Academic Search. The public-to-academic interest ratio was calculated for a comparison of subspecialties as well as for diseases and treatments. RESULTS For the selected 56 urological keywords, we found 226 617 591 video views on YouTube and 2 146 287 citations in the academic literature. The public-to-academic interest ratio was highest for the subspecialties robotic urology (ratio 6.3) and andrological urology (ratio 4.6). Prostate cancer was the central urological disease combining both a high public (20% of all video views) and academic interest (26% of all citations, ratio 0.8). Further diseases/treatments of high public interest were premature ejaculation (ratio 54.4), testicular cancer (ratio 11.4), erectile dysfunction (ratio 5.5) and kidney transplant (ratio 3.7). Urological treatments had a higher public-to-academic interest ratio (median ratio 0.25) than diseases (median ratio 0.05; P = 0.029). CONCLUSIONS A quantification of academic and public interest in the urological field is feasible using a novel new media-based methodology. We found several mismatches in public versus academic interest in urological diseases and treatments, which has implications for research strategies, conference planning and patient information projects. Regular re-assessments of the public and academic interest landscape can contribute to detecting and proving trends in the field of urology.

Effect of patient choice and hospital competition on service configuration and technology adoption within cancer surgery: a national, population-based study. Lancet Oncol 2017; 18:1445-1453. [PMID: 28986012 PMCID: PMC5666166 DOI: 10.1016/s1470-2045(17)30572-7] [Citation(s) in RCA: 60] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 07/07/2017] [Accepted: 07/17/2017] [Indexed: 01/16/2023]
Abstract
Background There is a scarcity of evidence about the role of patient choice and hospital competition policies on surgical cancer services. Previous evidence has shown that patients are prepared to bypass their nearest cancer centre to receive surgery at more distant centres that better meet their needs. In this national, population-based study we investigated the effect of patient mobility and hospital competition on service configuration and technology adoption in the National Health Service (NHS) in England, using prostate cancer surgery as a model. Methods We mapped all patients in England who underwent radical prostatectomy between Jan 1, 2010, and Dec 31, 2014, according to place of residence and treatment location. For each radical prostatectomy centre we analysed the effect of hospital competition (measured by use of a spatial competition index [SCI], with a score of 0 indicating weakest competition and 1 indicating strongest competition) and the effect of being an established robotic radical prostatectomy centre at the start of 2010 on net gains or losses of patients (difference between number of patients treated in a centre and number expected based on their residence), and the likelihood of closing their radical prostatectomy service. Findings Between Jan 1, 2010, and Dec 31, 2014, 19 256 patients underwent radical prostatectomy at an NHS provider in England. Of the 65 radical prostatectomy centres open at the start of the study period, 23 (35%) had a statistically significant net gain of patients during 2010–14. Ten (40%) of these 23 were established robotic centres. 37 (57%) of the 65 centres had a significant net loss of patients, of which two (5%) were established robotic centres and ten (27%) closed their radical prostatectomy service during the study period. Radical prostatectomy centres that closed were more likely to be located in areas with stronger competition (highest SCI quartile [0·87–0·92]; p=0·0081) than in areas with weaker competition. No robotic surgery centre closed irrespective of the size of net losses of patients. The number of centres performing robotic surgery increased from 12 (18%) of the 65 centres at the beginning of 2010 to 39 (71%) of 55 centres open at the end of 2014. Interpretation Competitive factors, in addition to policies advocating centralisation and the requirement to do minimum numbers of surgical procedures, have contributed to large-scale investment in equipment for robotic surgery without evidence of superior outcomes and contributed to the closure of cancer surgery units. If quality performance and outcome indicators are not available to guide patient choice, these policies could threaten health services' ability to deliver equitable and affordable cancer care.

Abstract
Considering the emerging advantages related to da Vinci Xi robotic platform, the aim of this study is to compare for the first time the operative outcomes of this tool to the previous da Vinci Si during transoral robotic surgery (TORS), both performed for squamous cell carcinomas (SCC) of the base of tongue (BOT). Intra- and peri-operative outcomes of eight patients with early stage (T1-T2) of the BOT carcinoma and undergoing TORS by means of the da Vinci Xi robotic platform (Xi-TORS) are compared with the da Vinci Si group ones (Si-TORS). With respect to Si-TORS group, Xi-TORS group demonstrated a significantly shorter overall operative time, console time, and intraoperative blood loss, as well as peri-operative pain intensity and length of mean hospital stays and nasogastric tube positioning. Considering recent advantages offered by surgical robotic techniques, the da Vinci Xi Surgical System preliminary outcomes could suggest its possible future routine implementation in BOT squamous cell carcinoma procedures.

Abstract
Many countries have introduced policies that enable patients to select a health care provider of their choice with the aim of improving the quality of care. However, there is little information about the drivers or the impact of patient mobility. Using administrative hospital data (n=19256) we analysed the mobility of prostate cancer patients who had radical surgery in England between 2010 and 2014. Our analysis, using geographic information systems and multivariable choice modelling, found that 33·5% (n=6465) of men bypassed their nearest prostate cancer surgical centre. Travel time had a strong impact on where patients moved to but was less of a factor for men who were younger, fitter, and more affluent (p always < 0.001). Men were more likely to move to hospitals that provided robotic prostate cancer surgery (odds ratio: 1.42, p<0.001) and to hospitals that employed surgeons with a strong media reputation (odds ratio: 2.18, p<0.001). Patient mobility occurred in the absence of validated measures of the quality of care, instead influenced by the adoption of robotic surgery and the reputation of individual clinicians. National policy based on patient choice and provider competition may have had a negative impact on equality of access, service capacity, and health system efficiency. PATIENT SUMMARY In this study, we assessed the reasons why men would choose to have prostate cancer surgery at a centre other than their nearest. We found that in England men were attracted to centres that carried out robotic surgery and employed surgeons with a national reputation.

Abstract
INTRODUCTION The goal of the study is to evaluate and report on the third-generation da Vinci surgical (Si) system malfunctions. METHODS A total of 1228 robotic surgeries were performed between January 2012 and December 2015 at our academic centre. All cases were performed by using a single, dual console, four-arm, da Vinci Si robot system. The three specialties included urology, gynecology, and thoracic surgery. Studied outcomes included the robotic surgical error types, immediate consequences, and operative side effects. Error rate trend with time was also examined. RESULTS Overall robotic malfunctions were documented on the da Vinci Si systems event log in 4.97% (61/1228) of the cases. The most common error was related to pressure sensors in the robotic arms indicating out of limit output. This recoverable fault was noted in 2.04% (25/1228) of cases. Other errors included unrecoverable electronic communication-related in 1.06% (13/1228) of cases, failed encoder error in 0.57% (7/1228), illuminator-related in 0.33% (4/1228), faulty switch in 0.24% (3/1228), battery-related failures in 0.24% (3/1228), and software/hardware error in 0.08% (1/1228) of cases. Surgical delay was reported only in one patient. No conversion to either open or laparoscopic occurred secondary to robotic malfunctions. In 2015, the incidence of robotic error rose to 1.71% (21/1228) from 0.81% (10/1228) in 2014. CONCLUSIONS Robotic malfunction is not infrequent in the current era of robotic surgery in various surgical subspecialties, but rarely consequential. Their seldom occurrence does not seem to affect patient safety or surgical outcome.

Abstract
BACKGROUND One of the perceived major drawbacks of minimally invasive techniques has always been its cost. This is especially true for the robotic approach and is one of the main reasons that has prevented its wider acceptance among hospitals and surgeons. The aim of our study was to evaluate the clinical outcomes and economic impact of robotic and open liver surgery in a single institution. METHODS Sixty-eight robotic and 55 open hepatectomies were performed at our institution between January 1, 2009 and December 31, 2013. Demographics, perioperative data, and postoperative outcomes were collected and compared between the two groups. An independent company performed the financial analysis. The economic parameters comprised direct variable costs, direct fixed costs, and indirect costs. RESULTS Mean estimated blood loss was significantly less in the robotic group (438 versus 727.8 mL; P = .038). Overall morbidity was significantly lower in the robotic group (22% versus 40%; P = .047). Clavien III/IV complications were also lower, with 4.4% in the robotic versus 16.3% in the open group (P = .043). The length of stay in the intensive care unit (ICU) was shorter for patients who underwent a robotic procedure (2.1 versus 3.3 days; P = .004). The average total cost, including readmissions, was $37,518 for robotic surgery and $41,948 for open technique. CONCLUSIONS Robotic liver resections had less overall morbidity, ICU, and hospital stay. This translates into decreased average costs for robotic surgery. These procedures are financially comparable to open resections and do not represent a financial burden to the hospital.

Abstract
Robotic technology is being utilized in multiple hepatobiliary procedures, including hepatic resections. The benefits of minimally invasive surgical approaches have been well documented; however, there is some concern that robotic liver surgery may be prohibitively costly and therefore should be limited on this basis. A single-institution, retrospective cohort study was performed of robotic and open liver resections performed for benign and malignant pathologies. Clinical and cost outcomes were analyzed using adjusted generalized linear regression models. Clinical and cost data for 71 robotic (RH) and 88 open (OH) hepatectomies were analyzed. Operative time was significantly longer in the RH group (303 vs. 253 min; p = 0.004). Length of stay was more than 2 days shorter in the RH group (4.2 vs. 6.5 days; p < 0.001). RH perioperative costs were higher ($6026 vs. $5479; p = 0.047); however, postoperative costs were significantly lower, resulting in lower total hospital direct costs compared with OH controls ($14,754 vs. $18,998; p = 0.001). Robotic assistance is safe and effective while performing major and minor liver resections. Despite increased perioperative costs, overall RH direct costs are not greater than OH, the current standard of care.

Adapting the robotic platform to small operating theaters: our experience with the side-docking technique for robotic-assisted laparoscopic prostatectomy. Surg Endosc 2016; 30:4464-8.

Abstract
INTRODUCTION Conventionally, in robotic-assisted laparoscopic prostatectomy (RALP), the robot is entered between the abducted legs of the patient. This approach may present drawbacks, including the limited access to the perineum, the inevitable abduction of the patient's legs, and the limited space available in small operating theaters. To overcome these problems, in our center, we use, from over 5 years, a side-docking technique. We herein describe our technique and a series of patients who underwent RALP using such side-docking procedure. METHODS In our department, we have applied the side-docking technique for over 5 years, mainly in RALP procedures. The series reported includes 268 men undergoing RALP ± extended lymph node dissection (ePLND) between mid-2010 and 2014. After trocart positioning, the robot is entered at a 45° angle compared to the patient's main axis, coming in from the right side. Patient's legs are minimally abducted to <10°. RESULTS Mean docking time, from skin incision to full docking was 13 min. 41 % (109/268) of patients underwent simultaneous ePLND, dissecting nodes up till at least the iliac bifurcation. No conversion to open surgery was required. External collisions are infrequent with this configuration: No re-docking was necessary in this cohort. CONCLUSIONS Side-docking of the da Vinci robot is a safe alternative for RALP. In our department, this technique has faced the proof of time and is routinely used.

Abstract
BACKGROUND AND OBJECTIVES The da Vinci Xi platform provides expanded movement of the arms relative to the base, theoretically allowing increased versatility in complex multi-field or multi-quadrant surgery. We describe the initial Xi experience in oncologic surgery at a tertiary cancer center. METHODS One hundred thirty unique robot-assisted procedures were performed using the Xi between 2014 and 2015, 112 of which were oncology surgeries. For procedures involving multiple quadrants, the robot was re-targeted. Complications were assessed according to Martin criteria and the Clavien-Dindo classification up to 90 days after operation. RESULTS Thirteen different operations were performed in five oncology subspecialties (urology, gynecology, thoracic, hepatobiliary, and gastrointestinal surgery). Median operative times ranged from 183 min for nephroureterectomy to 543 min for esophagogastrectomy. Median estimated blood loss did not exceed 200 ml for any of the categorized procedures . No patients were transfused intraoperatively and no positioning injuries occurred. Conversions to open operation occurred in three cases (2.7%), though not related to complications or technical considerations. Overall complication rate was 26% with major complication rate of 4%. Readmissions were necessary in 11 (10%) patients. CONCLUSIONS The da Vinci Xi can be safely assimilated into a surgical oncology program. The Xi offers versatility to various oncologic procedures with satisfactory complication and readmission rates.

Abstract
The pace of medical innovation continues to increase. The deployment of new technologies in surgery creates many ethical challenges including how to determine safety of the technology, what is the timing and process for deployment of a new technology, how are patients informed before undergoing a new technology or technique, how are the outcomes of a new technology evaluated and how are the responsibilities of individual patients and society at large balanced. Ethical considerations relevant to the implementation of ECMO and robotic surgery are explored to further discussion of how we can optimize the delicate balance between innovation and regulation.

Abstract
Robotic surgery is an exciting technology that allows the surgeon to sit at a computer console near the operating table, using mechanical arms with surgical instruments attached to them. This type of surgery is minimally invasive, and the procedure is performed through tiny incisions. This technology is widely used in the United States and is expected to evolve over time with an increase in the number and types of procedures.
