It was a systematic review and meta-analysis that aimed to compare the efficiency and safety of robot-assisted urological surgery using both the KangDuo and da Vinci robotic systems. The PubMed, Embase, and Cochrane Library databases were searched for all papers published through September 1, 2024. The focus was on English-language papers comparing the KangDuo surgical robot and the da Vinci system in urological procedures. The screening method focused on RCTs and cohort studies and followed strict criteria. Three cohort studies and two randomised controlled trials with 300 adult urological surgery patients met the inclusion criteria. These 150 patients were operated on with the KangDuo robotic system and 150 with the da Vinci system. The investigation showed that whereas KangDuo operations were slightly longer, intraoperative blood loss, hospital stay, and postoperative complication rates were similar. The KangDuo robotic system performs urological surgery as well as the da Vinci system, although it takes longer. Future large-scale multicenter randomized trials are recommended to gather further evidence and enhance clinical understanding.

The Hugo^™ robotic assisted surgery system is a relatively new robotic platform developed by Medtronic. The study objective was to describe the experience of using Hugo^™ robotic assisted surgery in gynecological surgeries and compare robotic assisted surgery-related outcomes between complex and non-complex gynecological patients at the Pacifica Salud Hospital. We performed secondary data retrospective analysis of 144 consecutive patients who underwent gynecological surgery with Hugo^™ robotic assisted surgery system (Medtronic) at the Pacifica Salud hospital in Panama City from July 19, 2021, to August 3, 2023. Complex patients were defined as those with one or more risk factors for surgery complications. Descriptive analysis of participants' sociodemographic and robotic assisted surgery-related characteristics. Due to the non-normal distribution of the RAS-related numeric variables, we compared these variables between complex and non-complex cases of gynecological patients using Kruskal-Wallis's test. The study found that Hugo^™ robotic assisted surgery system was safe for gynecological surgery in patients with and without risk factors for developing major surgery complications. None of the patients experienced any complications, and they had short hospital stays with low blood loss without requiring a blood transfusion. The Hugo^™ robotic assisted surgery system was technically sound and did not present technical failures. The results could be a reference for adopting this technology and developing best practices in the Latin American region.

To determine risk factors for urinary retention (UR) after robot-assisted radical cystectomy (RALC) with orthotopic neobladder diversion. A total of 269 patients who underwent RALC with orthotopic neobladder diversion from 2008 to 2019 at seven tertiary hospitals were retrospectively analyzed. There were 68 patients who had UR (UR arm) and 201 patients who did not have UR (no-UR arm). UR was defined as voiding dysfunction without catheterization or more than 100 mL of residual urine after voiding. Preoperative demographics, perioperative factors, pathology outcomes, and postoperative complications of UR and no-UR arms were compared and predictors of UR were identified. Among demographic factors, only gender proportion showed a difference, with male proportion being significantly lower in the UR arm than in the no-UR arm (81% vs 92%, p = 0.010). For perioperative outcomes, anastomosis site stricture (27% vs 11%, p = 0.003) and length of hospital stays (23 days vs. 19 days, p = 0.001) were significantly higher in the UR arm than in the no-UR arm. In multiple logistic regression analysis, female (OR 3.32, 95% CI: 1.43-7.72) and body mass index (BMI) (OR 1.10, 95% CI 1.00-1.20) were UR predictors. UR after RALC with orthotopic neobladder diversion is significantly increased in females. Multiple logistic regression analysis identified female and BMI elevation as UR predictors.

This paper explores the role of 5G-and future 6G networks-in advancing robotic telesurgery by minimizing latency and enhancing data reliability for real-time remote operations. With robotic telesurgery gaining prominence as a tool to democratize access to specialized surgical care, telecommunications infrastructure has become central to its feasibility and safety. Key elements include 5G's capacity for ultra-low latency and high data transfer rates, which support critical modalities such as kinesthetic, audiovisual, and tactile feedback in telesurgery. The paper outlines the differing latency demands of these modalities, noting that kinesthetic data are particularly sensitive, requiring ultra-low latency for effective surgeon feedback. In addition, the paper discusses the importance of network reliability and Quality-of-Service (QoS) agreements, alongside the potential for 6G networks to further reduce latency and integrate AI-driven predictive analytics. These advancements are positioned to not only broaden telesurgery's reach but also to enhance the precision and safety of procedures, setting the stage for a new paradigm in remote surgical care.

Previous studies have compared single-port robotic cholecystectomy (SPRC) to single-incision laparoscopic (SILC). However, there is not a systematic review and meta-analysis in patient with BMI ≥ 25 kg/m² even though higher BMI is a risk factor for gallstone disease, a common indication for cholecystectomy. PubMed, Scopus and Cochrane Library were searched for related literature. Studies and data were extracted by two independent reviewers. Inverse variances weighted mean differences (WMD) with random effects model were used for continues values and odds ratios (OR) with random effects model using the Mantel-Haenszel's formula were used for dichotomous value. Heterogeneity using Higgins I² and p values were calculated. Sensitivity analysis was performed for operative duration and intraoperative complications. In this meta-analysis, six studies involving a total of 734 patients examined SPRC and SILC. The analysis revealed a statistically significant increase in operative duration for SPRC compared to SILC, with a weighted mean difference of 26.67 min (95% CI 14.99, 38.34; I² = 93%; P_{heterogeneity} < 0.00001; P_overall < 0.00001). Regarding conversion to multi-port cholecystectomy (MC), no statistically significant difference was found, yielding an odds ratio of 0.94 (95% CI 0.36, 2.45; I² = 0%; P_{heterogeneity} = 0.78; P_overall = 0.89). Intra-operative blood loss showed non-significant differences, with a weighted mean difference of - 16.76 ml (95% CI - 48.56, 15.03; I² = 78%; P_{heterogeneity} = 0.03; P_overall = 0.30). Length of hospitalization was significantly reduced by approximately half a day for SPRC compared to SILC, with a weighted mean difference of - 0.52 days (95% CI - 0.89, - 0.14; I² = 0%; P_{heterogeneity} = 0.52; P_overall = 0.007). Intra-operative complications did not differ significantly between the techniques, resulting in an odds ratio of 0.59 (95% CI 0.19, 1.81; I² = 70%; P_{heterogeneity} = 0.04; P_overall = 0.36). Finally, two studies evaluated bile leak rates, concluding no significant difference with an odds ratio of 0.86 (95% CI 0.39, 1.88; I² = 23%; P_{heterogeneity} = 0.25; P_overall = 0.70). Sensitivity analyses indicated that no single study unduly influenced the results for operative duration, while one study was identified as a source of heterogeneity in intra-operative complications. SPRC is associated with longer operative duration, but shorter length of hospitalization in patients with BMI ≥ 25 kg/m², compared to laparoscopic. Future studies should aim to examine incisional hernias rates as well as determine the long-term outcomes. PROSPERO registration: CRD42024602514.

Single-port (SP) robotic surgery is a novel technology, and although there is emerging data, it remains limited in assessing single-port (SP) robot-assisted surgery as an alternative to multi-port (MP) platforms. To compare perioperative and postoperative outcomes between SP and MP robotic technologies for radical nephrectomy (RN). This is a retrospective cohort study of patients who have undergone robot-assisted radical nephrectomy using either the SP or MP technology. Baseline demographics, clinical, tumor-specific characteristics, and perioperative and postoperative outcomes were compared using χ², t-test, Fisher exact test, and Mann-Whitney U test. Multivariable analyses were conducted using robust, Poisson, and logistic regressions. A total of 341 patients underwent robotic RN with 47 patients (14%) in the SP group. The two groups exhibited similar baseline characteristics, with no significant differences in age, sex, body mass index, Charlson comorbidities index, and tumor laterality. However, SP group had a smaller average tumor size (5.1 cm vs 6.4 cm, p = 0.009). The SP had longer operative time (178 ± 84 min vs 142 ± 75 min; p = 0.011) but showed no significant difference in the estimated blood loss, blood transfusion rate, length of stay, overall 30-day and major complication rates. Controlling for other variables, SP was significantly associated with a longer operative time and shorter length of stay. SP is associated with longer operative time but offers advantages such as smaller incisions and shorter hospital stays with a comparative safety profile to MP for radical nephrectomy.

Artificial intelligence (AI) has emerged as a transformative tool in surgery, particularly in telesurgery and telementoring. However, its potential to enhance data transmission efficiency and reliability in these fields remains unclear. While previous reviews have explored the general applications of telesurgery and telementoring in specific surgical contexts, this review uniquely focuses on AI models designed to optimise data transmission and mitigate delays. We conducted a comprehensive literature search on PubMed and IEEE Xplore for studies published in English between 2010 and 2023, focusing on AI-driven, surgery-related, telemedicine, and delay-related research. This review includes methodologies from journals, conferences, and symposiums. Our analysis identified a total of twelve AI studies that focus on optimising network resources, enhancing edge computing, and developing delay-robust predictive applications. Specifically, three studies addressed wireless network resource optimisation, two proposed low-latency control and transfer learning algorithms for edge computing, and seven developed delay-robust applications, five of which focused on motion data, with the remaining two addressing visual and haptic data. These advancements lay the foundation for a truly holistic and context-aware telesurgical experience, significantly transforming remote surgical practice and education. By mapping the current role of AI in addressing delay-related challenges, this review highlights the pressing need for collaborative research to drive the evolution of telesurgery and telementoring in modern robotic surgery.

Miscommunication in the OR is a threat to patient safety and surgical efficiency. Our objective was to measure the frequency and causes of communication interference between robotic team members. We observed 78 robotic surgeries over 215 h. 65.4% were General Surgery, most commonly cholecystectomy, identifying Speech Communication Interference (SCI) events, defined as "surgery-related group discourse that is disrupted according to the goals of the communication or the physical and situational context of the exchange". We noted the causes and strategies to correct the miscommunication, near misses, and case delays associated with each SCI event. Post-surgery interviews supported observations and were analyzed thematically. Overall, we observed 687 SCI events (mean 8.8 ± 6.5 per case, 3.2 per hour), ranging from one to 28 per case. 48 (7.0%) occurred during docking and 136 (19.8%) occurred during a critical moment. The most common causes were concurrent tasks (66.1%); loud noises (10.8%) from patient cart, lightbox fan, and suction machine; and overlapping conversations (4.2%). 94.8% resulted in a case delay. These events distracted from monitoring patient safety and resulted in near misses. Mitigating strategies included leaning out of the surgeon console to repeat the message and employing a messenger. These findings help characterize miscommunication in robotic surgery. Possible interventions include microphones and headsets, positioning the surgeon console closer to the bedside, moving loud equipment further away, and upgrading the patient cart speaker.
