Exact data for docking time and the learning curve is missing. We describe for the first time the use of a laser-guided cart positioning to reduce the docking time. In this prospective monocentric study, the docking time was evalutated for a consecutive series of pelvic surgeries with the Hugo RAS system. In a subgroup, a cross-line laser was adapted at the cart for positioning using fix points at the ceiling. The medical personnel were classified as \"inexperienced\" with ≤ 5 consecutive dockings and as \"experienced\" with > 5 consecutive dockings. From 10/2023 to 08/2024, 82 procedures were performed with the Hugo RAS. For the evaluation 75 procedures could be considered. The mean docking time was 7.6 ± 3.5 min. There was a reduction in docking time from 13.5 ± 3.7 min in the first 5 procedures to 4.4 ± 0.9 min in the last 5 procedures (p < 0.001). Docking with laser (n = 45) was faster than without laser (n = 30) (6.2 ± 2.5 vs. 9.8 ± 3.7 min, p < 0.001). Faster docking time was observed with inexperienced surgical nursing staff with laser than without laser (10.4 ± 3.7 vs. 5.4 ± 1.4 min; p < 0.001). With experienced nursing staff, the laser had no influence (6.6 ± 1.3 vs. 6.7 ± 2.9 min; p = 0.9). As a reference docking time for daVinci Xi procedures was 2.4 ± 1.7 min (n = 5). Laser-guided cart positioning has a significant impact on docking time, especially for unexperienced medical personnel. Especially in the times of experienced staff shortage, laser-guided cart positioning can save operating time.","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"46"},"PeriodicalIF":2.2,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11703870/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142956740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout the research process, we conducted an extensive literature search across numerous databases, including PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), CQVIP, and Wanfang. Based on the literature screening criteria, we selected six studies, encompassing 358 cases of femoral neck fracture patients, for this meta-analysis. The study evaluated the effectiveness of TiRobot-assisted versus freehand placement of the Femoral Neck System (FNS). The results indicate that the TiRobot-assisted group demonstrated significant advantages in several surgical parameters. Specifically, the robot-assisted group showed superior outcomes regarding the frequency of guide pin insertion, frequency of X-ray fluoroscopy, operative time, invasive fixation time, intraoperative blood loss and incision length (MD < 0, p < 0.05). Furthermore, there was a significant difference in the Harris score, between the TiRobot-assisted group and the traditional freehand group (MD > 0, p < 0.05). However, the two groups had no significant differences concerning postoperative complications, fracture healing time, and fracture healing rate (p > 0.05). In conclusion, the comprehensive analysis suggests that the TiRobot-assisted technique has distinct advantages over the traditional freehand technique in treating femoral neck fractures. TiRobot-assisted technology, owing to its enhanced safety and efficacy, minimizes surgical trauma and expedites postoperative recovery.","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"43"},"PeriodicalIF":2.2,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142933056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We, therefore, studied hemodynamic and respiratory changes due to CO2 insufflation and lateral decubitus in children undergoing R-RALP and their effects on regional tissue oxygenation. Between 1/2021 and 7/2024, children affected by ureteropelvic joint obstruction (UPJO) underwent a pyeloplasty by R-RALP at Necker Enfants Malades Hospital (Paris, France), using a standardized surgical technique and a lung-protecting anesthetic protocol aimed to prevent hypercarbia. Cerebral and renal Near InfraRed Spectroscopy (NIRS) were added to standard monitoring. Mean monitoring parameters and NIRS values were derived from the prospectively kept continuous reading at eight preset points and analyzed. 37 patients were prospectively included (21 males), with a mean age of 6.0 ± 3.9 years, and mean body weight of 22.5 ± 11.3 kg; 15 patients were operated on in Left Lateral Decubitus (LLD) and 22 in Right Lateral Decubitus (RLD). No different LLD/RLD time trends were observed for standard monitoring parameters and NIRS measurements. Conversely, EtCO2 was higher in the RLD group at trocars insertion (T4, + 3.3 mmHg), beginning of CO2 insufflation (T5, + 2.9), and 45 min after the start of the procedure (T6, + 3.1). At the same time points, Pplat was higher in the LLD group at T4 (+ 3.0 cmH2O); T5, (+ 3.4) and T6 (+ 4.7). During R-RALP, the combination of RLD and CO2 insufflation promotes hypercarbia, while LLD requires increasing Pplat pressures, potentially favoring lung injury and hemodynamic instability during prolonged procedures.","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"42"},"PeriodicalIF":2.2,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142928219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study compared short-term outcomes of high tie (HT) and low tie (LT) ligation of the inferior mesenteric artery in 455 patients undergoing robotic rectal cancer surgery between May 2018 and July 2022. Propensity score matching (PSM) minimized selection bias, resulting in 124 patients in each group. The LT group had a longer operative time (P < 0.001), but there were no significant differences in estimated blood loss, lymph node harvest, lymph node positivity, AJCC stage, hospital stay, or costs. Postoperative complications, 30-day mortality, and reoperations were also comparable. Univariate analysis identified hypoalbuminaemia, low tumor location, ASA scores III, and neoadjuvant chemoradiotherapy as risk factors for postoperative complications. Multivariate analysis confirmed low serum albumin and low tumor location as significant factors. Importantly, HT did not increase the risk of complications in either analysis. These findings indicate that high ligation does not adversely affect short-term outcomes and highlight the need for further research to refine surgical strategies.","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"41"},"PeriodicalIF":2.2,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142928169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the integration of robotic assistance in a series of 85 consecutive robot-assisted microsurgical (RAMS) operations.

The study utilized a prospective database encompassing all robot-assisted microsurgical cases using the Symani surgical system from February until December 2023. A total of 85 robot-assisted operations were analyzed, showing a broad application across various types of reconstructive needs, predominantly in lower extremity repairs (n = 41). There were 68 free flap reconstructions (80.0%), ten nerve transfers (11.8%), four targeted muscle reinnervations (TMR; 4.7%), two lymphovenous anastomoses (2.4%) and one arterial reconstruction. The adoption of both traditional and digital exoscopic magnification systems was optimized for each surgical context. The operating room setup and infrastructural challenges for the different anatomic regions are presented. The introduction of robot-assisted surgery entailed overcoming challenges such as adapting to the lack of haptic feedback and navigating ergonomic constraints. Despite these hurdles, including higher operational costs and increased surgery durations, the precision and ergonomic benefits offered by robotic systems may be substantial. Potential solutions and tips to improve the operating times include frequent cleaning of the instruments, active surgical assistance, and rigorous presurgical planning of the logistical setup in the operating room.

We conducted an extensive search on PubMed, Scopus and Web of Science, inserting the following keywords: \"robotic liver transection, robotic hepatic transection\" and focusing particularly on technical reports and paper regarding new surgical methods. This search resulted in a total of 13 different surgical techniques. All the methods described can be classified into two categories the \"hybrid techniques\" and the \"fully robotic techniques\" which are based, respectively, on the combined use of laparoscopic and robotic instrumentation or exclusively robotic devices. Another fundamental difference is the division between \"one-surgeon\" and \"two-surgeon techniques\", which depends on the level of expertise required of the assistant surgeon at the operating table. This is the first comprehensive review on this topic.

However, conventional stereotactic neurosurgeries often rely on mechanical stereotactic head frames and preoperative imaging, leading to suboptimal results due to the invisibility and the contact with patient's head, which may cause additional harm. This paper presents a frameless, MRI-guided stereotactic neurosurgical robotic system. The robot features a seven-degree-of-freedom (7-DOF) remote center of motion, with five DOFs for preoperative trajectory alignment to the target lesion and two DOFs for defining the depth and twisting motion of the needle during insertion, thus to minimize tissue damage. The system employs interactive MRI guidance for real-time visualization of the puncture process, showing great potential in reducing surgery time, enhancing targeting accuracy, and improving safety. Experiments were conducted on the proposed system to evaluate signal-to-noise ratio (SNR) and geometric distortion. During the simultaneous operation and imaging, the system demonstrated less than 10.02% SNR attenuation and less than 0.1% geometric distortion, ensuring image usability. The free-space positioning accuracy of the system was evaluated using a laser tracker, revealing a tip position repeatability error within 0.3 ± 0.1 mm.","PeriodicalId":47616,"journal":{"name":"Journal of Robotic Surgery","volume":"19 1","pages":"35"},"PeriodicalIF":2.2,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142910781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
