BACKGROUND: Minimal access surgery (MAS) is well-established in urological surgery. However, MAS is technically demanding and associated with a prolonged learning curve. Robot-assisted laparoscopy has made progress in overcoming these challenges. OBJECTIVE: The aim of this study was to evaluate the feasibility of a new robot-assisted surgical system (the Versius Surgical System; CMR Surgical, Cambridge, UK) for renal and prostate procedures in a preclinical setting, at the IDEAL-D phase 0. DESIGN, SETTING, AND PARTICIPANTS: Cadaveric sessions were conducted to evaluate the ability of the system to complete all surgical steps required for a radical nephrectomy, prostatectomy, and pelvic lymph node dissection. A live animal (porcine) model was also used to assess the surgical device in performing radical nephrectomy safely and effectively. Procedures were performed by experienced renal and prostate surgeons, supported by a full operating room team. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Surgical access and reach were evaluated by the lead surgeon using a visual analogue scale. The precise surgical steps conducted to make the assessment that the procedures could be completed fully were recorded, as well as instruments used (including manual laparoscopic instruments) and endoscope angle. RESULTS AND LIMITATIONS: In total, all 24 procedures were completed successfully in cadavers by eight different lead surgeons. Positioning of the ports and bedside units reflected the lead surgeon's preferred laparoscopic set-up and enabled good surgical access and reach, as quantified by a median visual analogue score of ≥6.5. Radical nephrectomies performed in pigs were all completed successfully, with no device- or non-device-related intraoperative complications recorded. Testing in human cadavers and pig models balances the bias introduced by each model; however, it is impossible to completely replicate the experience and performance of the robot for surgery in live humans.

BACKGROUND: The World Health Organization (WHO) coordinates the Global Invasive Bacterial Vaccine-Preventable Diseases (IB-VPD) Surveillance Network to support vaccine introduction decisions and use. The network was established to strengthen surveillance and laboratory confirmation of meningitis caused by Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis. METHODS: Sentinel hospitals report cases of children <5 years of age hospitalized for suspected meningitis. Laboratories report confirmatory testing results and strain characterization tested by polymerase chain reaction. In 2019, the network included 123 laboratories that follow validated, standardized testing and reporting strategies. RESULTS: From 2014 through 2019, >137 000 suspected meningitis cases were reported by 58 participating countries, with 44.6% (n = 61 386) reported from countries in the WHO African Region. More than half (56.6%, n = 77 873) were among children <1 year of age, and 4.0% (n = 4010) died among those with reported disease outcome. Among suspected meningitis cases, 8.6% (n = 11 798) were classified as probable bacterial meningitis. One of 3 bacterial pathogens was identified in 30.3% (n = 3576) of these cases, namely S. pneumoniae (n = 2177 [60.9%]), H. influenzae (n = 633 [17.7%]), and N. meningitidis (n = 766 [21.4%]). Among confirmed bacterial meningitis cases with outcome reported, 11.0% died; case fatality ratio varied by pathogen (S. pneumoniae, 12.2%; H. influenzae, 6.1%; N. meningitidis, 11.0%). Among the 277 children who died with confirmed bacterial meningitis, 189 (68.2%) had confirmed S. pneumoniae. The proportion of pneumococcal cases with pneumococcal conjugate vaccine (PCV) serotypes decreased as the number of countries implementing PCV increased, from 77.8% (n = 273) to 47.5% (n = 248). Of 397 H. influenzae specimens serotyped, 49.1% (n = 195) were type b. Predominant N. meningitidis serogroups varied by region. CONCLUSIONS: This multitier, globa

Robot-assisted laparoscopy has been developed to overcome some of the important limitations of conventional laparoscopy. In particular, the provision of stable magnified three-dimensional vision, tremor filtering, motion scaling, and articulated instruments with robot-assisted surgery has the potential to enable more surgeons to perform more complex surgery compared with conventional laparoscopy. The aim of this study was to evaluate the utility of a new robot-assisted surgical system (Versius, CMR Surgical, Cambridge, UK) for gynecologic procedures in a preclinical setting. Cadaveric sessions were conducted to evaluate the ability of the system to complete all surgical steps required for a robot-assisted total laparoscopy hysterectomy. A live animal (porcine) model was used to assess the system in performing oviduct removal as a surrogate for robot-assisted total laparoscopy hysterectomy. Procedures were performed by experienced gynecologic surgeons, supported by a surgical team. The precise surgical steps conducted to conclude that the procedures could be fully completed were systematically recorded, as well as instruments used and endoscope angle. In total, six gynecologic procedures were performed in cadavers by four surgeons; 16/17 procedures were completed successfully. Positioning of the ports and bedside units reflected the surgeons’ preferred laparoscopic setup and enabled good surgical access and reach, as exemplified by the high procedure completion rate. Oviduct removal procedures performed in pigs were all completed successfully by a single surgeon. This preclinical study of a new robot-assisted surgical system for gynecologic procedures demonstrated the safety and effectiveness of the system in cadaver and porcine models. Further studies are required to assess its clinical utility.
