Abstract
Robotic-assisted surgery (RAS) has a variety of theoretical advantages, including tremor filtration, optimal visualization, and improvement of surgeon ergonomics. Though it has achieved wide application in pediatric urology, the majority of pediatric general surgeons do not employ RAS. This study reports our institution's experience with RAS on a pediatric general surgery team. Following IRB approval, a retrospective review of all pediatric patients at our academic children's hospital who underwent RAS between 2017 and 2022 for pediatric general surgical conditions was performed. Patient demographics, operation performed, operating time, complications, and recovery were evaluated. A total of 159 children underwent RAS, increasing from 10 patients in 2017 to 59 patients in 2022. The median age and weight were 15.3 years and 76.4 kg, and 121 (76.1%) were female. The application of RAS was successful in all cases. There were no intraoperative complications and no conversions to an open approach. Eleven patients (6.9%) had unplanned presentations to the emergency department within 30 days. Five of these patients (3.1%) required admission to the hospital. This study demonstrates that the application of RAS in an academic pediatric general surgery practice is feasible and safe. The application of RAS to pediatric general surgery should continue to increase as operative teams increase their experience and comfort.Level of evidence Level IV.

Abstract
The uptake of robot-assisted surgery has continuously grown since its advent in the 1990s. While robot-assisted surgery is well-established in adult surgery, the rate of uptake in paediatric surgical centres has been slower. The advantages of a robot-assisted system, such as improved visibility, dexterity, and ergonomics, could make it a superior choice over the traditional laparoscopic approach. However, its implementation in the paediatric surgery arena has been limited primarily due to the unavailability of appropriately sized instruments as per paediatric body habitus, therefore, requiring more technologically advanced systems. The Versius surgical robotic system is a new modular platform that offers several benefits such as articulated instruments which pass through conventional 5 mm ports, compact arms for easier manoeuvrability and patient access, the ability to mimic conventional port placements, and adaptive machine learning concepts. Prior to its introduction to paediatric surgery, it needs to go through a careful pre-clinical and clinical research program.

Abstract
Abstract
Background
The minimally invasive surgery (MIS) in term of robot-assisted surgery changed in a dramatic way the surgical approach either in adults or children. For many specialties (urology, gynecology, general surgery) robotic surgery rapidly became the gold standard for some procedures, while the experience in pediatric population is not wide for some reasons. The aim of this study is to retrospective analyze trends of application of robotic surgery in pediatric patients across the country, focusing on indications, limitations, development, and training acquired by national experience and in comparison to the literature.
Methods
We made a retrospective multicenter study on behalf of Italian Society of Pediatric Surgery. We performed a census among all pediatric surgery units in the country to enroll those performing robotic surgery on children between 2013 and 2019.
Results
We enrolled 7 pediatric surgery referral Centers (Ancona, Bologna, Brescia, Genova, Pavia, Pescara, Siena). A total of 303 patients were included in the study, 164 males (54%) and 139 females (46%). The most commonly performed interventions for each anatomic area were respectively atypical pulmonary resection (38%), pyeloplasty (49%), and fundoplication (30%).
Conclusions
Since its first application in Italy, about 10 years ago, several considerations were made about application and feasibility of robotics in children.

Abstract
BACKGROUND The rising prevalence of childhood obesity and concomitant increase in comorbid disease pose significant challenges for the health care system. While mounting evidence demonstrates the safety and efficacy of bariatric surgery for severely obese adolescents, the potential role of robotic technology has not been well defined. OBJECTIVE The aim of this study was to establish the safety and efficacy of robotic-assisted laparoscopic sleeve gastrectomy (RSG) in treating severe adolescent obesity. In addition, 30-day outcomes and hospital charges were compared to subjects undergoing RSG versus laparoscopic sleeve gastrectomy (LSG). METHODS A retrospective analysis of 28 subjects (14 LSG vs. 14 RSG) at a single institution was conducted. Data collection included demographics, body mass index, comorbidities, hospital length of stay (LOS), operative time, 30-day outcomes, and hospital charges. Analysis was performed using chi-square, Fisher's exact, and nonparametric Wilcoxon rank sum tests. RESULTS There were no differences in subject demographics or comorbidities. While median operative time was longer for RSG vs. LSG (132 vs. 100 min, p = 0.0002), the median LOS for RSG compared to LSG was shorter (69.6 vs. 75.9 h, p = 0.0094). In addition, RSG-related hospital charges were higher ($56,646 vs. $49,498, p = 0.0366). No significant differences in post-operative outcomes or complications were observed. CONCLUSIONS RSG is equally safe and efficacious when compared to LSG among adolescents. Similar to studies in adults, LOS is shortened while hospital charges are higher. Larger prospective studies are needed to gain insight regarding cost benefit ratios.

Abstract
INTRODUCTION In recent years, the use of robotic-assisted surgery (RAS) has expanded within pediatric surgery. Although increasing numbers of pediatric RAS case-series have been published, the level of evidence remains unclear, with authors mainly focusing on the comparison with open surgery rather than the corresponding laparoscopic approach. The aim of this study was to critically appraise the published literature comparing pediatric RAS with conventional minimally invasive surgery (MIS) in order to evaluate the current best level of evidence. MATERIALS AND METHODS A systematic literature-based search for studies comparing pediatric RAS with corresponding MIS procedures was performed using multiple electronic databases and sources. The level of evidence was determined using the Oxford Centre for Evidence-based Medicine (OCEBM) criteria. RESULTS A total of 20 studies met defined inclusion criteria, reporting on five different procedures: fundoplication (n=8), pyeloplasty (n=8), nephrectomy (n=2), gastric banding (n=1), and sleeve gastrectomy (n=1). Included publications comprised 5 systematic reviews and 15 cohort/case-control studies (OCEBM Level 3 and 4, respectively). No studies of OCEBM Level 1 or 2 were identified. Limited evidence indicated reduced operative time (pyeloplasty) and shorter hospital stay (fundoplication) for pediatric RAS, whereas disadvantages were longer operative time (fundoplication, nephrectomy, gastric banding, and sleeve gastrectomy) and higher total costs (fundoplication and sleeve gastrectomy). There were no differences reported for complications, success rates, or short-term outcomes between pediatric RAS and conventional MIS in these procedures. Inconsistency was found in study design and follow-up with large clinical heterogeneity. CONCLUSIONS The best available evidence for pediatric RAS is currently OCEBM Level 3, relating only to fundoplication and pyeloplasty. Therefore, higher-quality studies and comparative data for other RAS procedures in pediatric surgery are required.

Abstract
Since the introduction of robotic surgery in children in 2001, it has been employed by select pediatric laparoscopic surgeons, but not to the degree of adult surgical specialists. It has been suggested that the technical capabilities of the robot may be ideal for complex pediatric surgical cases that require intricate dissection. However, due to the size constraints of the robot for small pediatric patients, the tight financial margins that pediatric hospitals face, and the lack of high level data displaying patient benefit when compared to conventional laparoscopic surgery, it may be some time before the robotic surgical platform is widely embraced in pediatric surgical practice.

Abstract
BACKGROUND AND PURPOSE Surgeons anecdotally report awareness of nontactile sensory cues that compensate for absent haptic feedback in robot-assisted surgery. This study investigates this poorly understood adaptive process by evaluating frequency of in vivo suture damage. PATIENTS AND METHODS Consecutive cases of children undergoing robot-assisted dismembered pyeloplasty were examined. Suture damage was defined as incomplete (i.e., fraying) or complete (i.e., broken) loss of thread integrity and prospectively recorded with clinical data. Suture technique, size, and robotic instruments used for suturing were subjected to post hoc analysis. Statistical analysis was undertaken using appropriate nonparametric tests. RESULTS Overall frequency of suture damage was 2.6% among 1135 sutures used in 52 patients. The mean number of sutures used for cases in this series was 22 (standard deviation±6). There was a significant inverse trend between surgeon experience and suture damage frequency (P=0.014), implying that greater surgeon experience was associated with less suture damage. The impact of experience on suture damage was most apparent when comparing the earliest quartile subgroup (Q1) with the later three quartile subgroups (Q2-Q4) (P<0.001). Plateau of suture damage frequency was seen after approximately 28 cases. Continuous sutures had significantly higher damage frequency compared with interrupted sutures (P=0.022). Significantly higher frequency of suture damage was seen with cases in which forceps instruments were used for suturing compared with paired needle drivers (1.4% vs 7.1%, P<0.001). All events of inadvertent tissue injury involved damage to exposed edges of the renal pelvis (n=5). CONCLUSIONS Suture damage is likely to be encountered during the learning curve of robot-assisted surgery but decreases with surgeon experience. Preferential use of larger suture size, interrupted sutures, and paired needle driver instruments may help to minimize suture damage. Experience-related perceptual skills that compensate for haptic loss are likely to be acquirable in a preclinical simulation environment.

Abstract
BACKGROUND Robotic surgery offers technological solutions to current challenges of minimal access surgery, particularly for delicate and dexterous procedures within spatially constrained operative workspaces in children. The first robotic surgical procedure in a child was reported in April 2001. This review aims to examine the literature for global case volumes, trends, and quality of evidence for the first decade of robotic surgery in children. METHODS A systematic literature search was performed for all reported cases of robotic surgery in children during the period of April 2001 to March 2012. RESULTS Following identification of 220 relevant articles, 137 articles were included, reporting 2393 procedures in 1840 patients. The most prevalent gastrointestinal, genitourinary, and thoracic procedures were fundoplication, pyeloplasty, and lobectomy, respectively. There was a progressive trend of increasing number of publications and case volumes over time. The net overall reported conversion rate was 2.5%. The rate of reported robot malfunctions or failures was 0.5%. CONCLUSIONS Robotic surgery is an expanding and diffusing innovation in pediatric surgery. Future evolution and evaluation should occur simultaneously, such that wider clinical uptake may be led by higher quality and level of evidence literature.

Abstract
BACKGROUND This study was performed to validate the feasibility and role of image-guided robotic surgery using preoperative computed tomography (CT) images for the treatment of gastric cancer. METHODS Twelve patients scheduled to undergo robotic gastrectomy for gastric cancer were registered. Vessels encountered during gastrectomy were reconstructed using 3D software and their anatomical variation was evaluated using preoperatively performed CT-angiography. The vascular information was transferred to a robot console using a multi-input display mode. Radiologic findings acquired from preoperative CT by the radiologist were compared with intraoperative findings of the surgeon. This study is registered with www.clinicaltrials.gov as NCT01338948. RESULTS All 12 robotic gastrectomies were performed without any problems. All anatomical data acquired using 3D software were transferred successfully during surgery. Intraoperative vascular images depicted vasculatures around the stomach and could identify important vascular variations. During surgery, relevant vascular information led the surgeon to branch sites and facilitated lymphadenectomy around the vessels. Image-guidance during the operation provided a vascular map and enabled the surgeon to avoid accidental bleeding and damage to other organs by preventing vascular injuries. CONCLUSION Image-guided robotic surgery for gastric cancer using preoperative CT-angiography reconstructed during operation by a surgically trained radiologist who could adjust the images by anticipating the operative procedure was feasible and improved the efficiency of surgery by eliminating the possibility of vascular injuries.

Abstract
BACKGROUND Both our teams were the first to implement pediatric robotic surgery in France. The aim of this study was to define the key points we brought to light so other pediatric teams that want to set up a robotic surgery program will benefit. METHODS We reviewed the medical records of all children who underwent robotic surgery between Nov 2007 and June 2011 in both departments, including patient data, installation and changes, operative time, hospital stay, intraoperative complications, and postoperative outcome. The department's internal organization, the organization within the hospital complex, and cost were evaluated. RESULTS A total of 96 procedures were evaluated. There were 38 girls and 56 boys with average age at surgery of 7.6 years (range, 0.7-18 years) and average weight of 26 kg (range, 6-77 kg). Thirty-six patients had general surgery, 57 patients urologic surgery, and 1 thoracic surgery. Overall average operative time was 189 min (range, 70-550 min), and average hospital stay was 6.4 days (range, 2-24 days). The procedures of 3 patients were converted. Median follow-up was 18 months (range, 0.5-43 months). Robotic surgical procedure had an extra cost of <euro>1934 compared to conventional open surgery. CONCLUSIONS Our experience was similar to the findings described in the literature for feasibility, security, and patient outcomes; we had an overall operative success rate of 97 %. Three main actors are concerned in the implementation of a robotic pediatric surgery program: surgeons and anesthetists, nurses, and the administration. The surgeon is at the starting point with motivation for minimally invasive surgery without laparoscopic constraints. We found that it was possible to implement a long-lasting robotic surgery program with comparable quality of care.

Abstract
BACKGROUND The purpose of this study was to assess the safety and feasibility of performing robot-assisted pediatric surgery using the da Vinci Surgical System in a variety of surgical procedures. METHODS A retrospective review of 144 robot-assisted pediatric surgical procedures performed in our institution between June 2004 and December 2007 was done. The procedures included the following: 39 fundoplications; 34 cholecystectomies; 25 gastric bandings; 13 splenectomies; 4 anorectal pull-through operations for imperforate anus; 4 nephrectomies; 4 appendectomies; 4 sympathectomies; 3 choledochal cyst excisions with hepaticojejunostomies; 3 inguinal hernia repairs; two each of the following: liver cyst excision, repair of congenital diaphragmatic hernia, Heller's myotomy, and ovarian cyst excision; and one each of the following: duodeno-duodenostomy, adrenalectomy, and hysterectomy. RESULTS A total of 134 procedures were successfully completed without conversion; 7 additional cases were converted to open surgery, and 3 were converted to laparoscopic surgery. There were no system failures (e.g., setup joint, arm, or camera malfunction; power error; monocular or binocular loss; metal fatigue or break of surgeon's console hand piece; software incompatibility). There was one esophageal perforation and two cases of transient dysphagia following Nissen fundoplication. The mean patient age was 8.9 years, and the mean patient weight was 57 kg. CONCLUSIONS Robot-assisted surgery appears to be safe and feasible for a number of pediatric surgical procedures. Further system improvement and randomized studies are required to evaluate the benefits, if any, and the long-term outcomes of robotic surgery.

Abstract
BACKGROUND Robotic surgery is a new technology which may expand the variety of operations a surgeon can perform with minimally invasive techniques. We present a retrospective review of our first 100 consecutive robotic cases in children. METHODS A three-arm robot was used with one camera arm and two instrument arms. Additional accessory ports were utilized as necessary. Two different attending surgeons performed the procedures. RESULTS Twenty-four different types of procedures were completed using the robot. The majority of the procedures (89%) were abdominal procedures with 11% thoracic. No urology or cardiac procedures were performed. Age ranged from 1 day to 23 years with an average age of 8.4 years. Weight ranged from 2.2 to 103 kg with a median weight of 27.9 kg. Twenty-two patients were less than 10.0 kg. Examples of cases included gastrointestinal (GI) surgery, hepatobiliary, surgical oncology, and congenital anomalies. The overall majority of cases had never been performed minimally invasively by the authors. The overall intraoperative conversion rate to open surgery was 13%. One case (1%) was converted to thoracoscopic because of lack of domain for the articulating instruments. No conversions or complications occurred as a result of injuries from the robotic instruments. Interestingly, four abdominal cases were converted to open surgery due to equipment failures or injuries from standard laparoscopic instruments used through non-robotic accessory ports. CONCLUSIONS Robotic surgery is safe and effective in children. An enormous variety of cases can be safely performed including complex cases in neonates and small children. Simple operations such as cholecystectomies have minimal advantages by using robotic technology but can serve as excellent teaching tools for residents and newcomers to this form of minimally invasive surgery (MIS). The technology is ideal for complex hepatobiliary cases and thoracic surgery, particularly solid chest masses.

BACKGROUND Prenatal cardiac interventions (PCI) for human fetal aortic valve (AoV) stenosis can reduce left ventricular hypoplasia and restore ventricular growth and function. However, 'freehand' needle delivery from the maternal skin through the uterine wall, fetal chest and ventricular apex to cross the fetal AoV remains technically challenging and time intensive, and is the rate-limiting step in the procedure. METHODS We developed a computer-assisted navigation (CANav) system that tracks the position and orientation of a two-dimensional (2D) ultrasound image relative to the trajectory of an electromagnetic (EM) embedded needle and stylet. We tested the CANav system in vitro using a water bath phantom, then in vivo using adult rats and pregnant (fetal) sheep. RESULTS The CANav system accurately tracked the delivered needle position in both in vitro phantom and adult rat model experiments. We performed 22 PCI attempts with or without CANav in a fetal sheep model. Maternal laparotomy was required to adjust the fetal position in 50% of the procedures. The time required to deliver the needle from the skin into the left ventricle (LV) using CANav was 2.9 +/- 1.7 (range 2-7) min (n = 14) vs. 5.5 +/- 4.3 (range 1-12) min (n = 8) without CANav (p < 0.05). The time needed to cross the aortic valve once the needle was within the LV was similar with and without CANav (p = 0.19). CONCLUSIONS CANav reduces the PCI time required to accurately deliver a needle to the fetal heart. Adaptations of this technical approach may be relevant to other congenital cardiac conditions and ultrasound-guided medical procedures.
