Simulation-based training in robotic surgery education: bibliometric analysis and visualization.

Simulation-based robotic surgery training may help surgeons gain operative skills and experience in the simulation environment. This bibliometric analysis examined the development of simulation-based training for robotic surgical education. Articles pertaining to robotic surgical simulation training that were included in the Web of Science Core Collection up to April 25, 2024, were included. The temporal patterns in published paper numbers were evaluated using Microsoft Excel software, and the data regarding co-authorship and keyword co-occurrence were analyzed and visualized using the VOSviewer and SCImago Graphica tools. A total of 594 papers on simulation-based training for robotic surgical education were evaluated in this study. The United States and United Kingdom were the leading contributors in this field. The most published authors were Professor Ahmed Kamran (23 publications) and Prokar Dasgupta (22 publications). The highest number of papers was published in the journal titled "Surgical Endoscopy and Other Interventional Techniques." The most common keywords were "virtual reality," "curriculum," "robotic surgery simulator," "assessment," and "learning curve." Our study offers a detailed overview of international research on simulation-based training for robotic surgical education, including the publishing countries, institutions, authors, journals, and research hotspots. It also methodically summarizes the state of knowledge in the area, and provides definite directions and concepts for further in-depth analysis.

Assessment of the evolution of psychomotor skills in the robotic surgery simulation process.

Robotic surgery is a rapidly expanding field, given the wide variety of new robotic platforms emerging. Looking at the training of surgeons in robotic surgery is of extreme necessity and urgency, considering the ongoing technological advancements. In this research, the performance during the virtual reality simulation phase of training for robotic surgery was analyzed. It was observed that, in addition to the lack of consensus among societies regarding the required simulation hours, there is no guidance on the best curriculum to be adopted. From the data in this study, it can be inferred that the more advanced skills have fewer proficient individuals, meaning that fewer surgeons in training have reached proficiency in all skill exercises. Even with differences in the number of exercises performed proficiently between groups that underwent varying amounts of simulation time, there is no statistically significant difference in the proportion between them.

Current status of resident simulation training curricula: pearls and pitfalls.

Residency programs are required to incorporate simulation into their training program. Ideally, simulation provides a safe environment for a trainee to be exposed to both common and challenging clinical scenarios. The purpose of this review is to detail the current state of the most commonly used laparoscopic, endoscopic, and robotic surgery simulation programs in general surgery residency education, including resources required for successful implementation and benchmarks for evaluation. Members of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Resident and Fellow Task Force (RAFT) Committee performed a literature review using PubMed and training websites. Information regarding the components of the most commonly used laparoscopic, endoscopic, and/or robotic simulation curriculum, including both formal and informal benchmarks for evaluating training competence, were collected. Laparoscopic simulation revolves around the Fundamentals of Laparoscopic Surgery (FLS). Proficiency-based as well as virtual simulation have been utilized for FLS training curricula. Challenges include less direct translation to the technical complexities that can arise in laparoscopic surgery. Endoscopic simulation focuses on the Fundamentals of Endoscopic Surgery. There are virtual reality simulation platforms that can be used for skills assessment and training. Challenges include simulator types and access, as well as structured mentoring and feedback. Robotic simulation training curricula have not been standardized. Simulation includes one primary technology, which can be prohibitive based on cost and requirements for onboarding. While surgical simulation seems to be a fundamental and integrated part of surgical training, it requires a significant number of resources, which can be daunting for residency training programs. Regardless of the barriers outlined, the need for surgical simulation in laparoscopy, endoscopy, and robotics at surgical education training programs is clear.

Results of an exploratory survey within ESTS membership in 2022 on current trend of robotic-assisted thoracic surgery and its training perspectives.

Robotic-assisted thoracic surgery (RATS) is increasingly used in our specialty. We surveyed European Society of Thoracic Surgeons membership with the objective to determine current status of robotic thoracic surgery practice including training perspectives. A survey of 17 questions was rolled out with 1 surgeon per unit responses considered as acceptable. A total of 174 responses were obtained; 56% (97) were board-certified thoracic surgeons; 28% (49) were unit heads. Most responses came from Italy (20); 22% (38) had no robot in their institutions, 31% (54) had limited access and only 17% (30) had full access including proctoring. Da Vinci Xi was the commonest system in 56% (96) centres, 25% (41) of them had dual console in all systems, whereas RATS simulator was available only in half (51.18% or 87). Video-assisted thoracic surgery (VATS) was the most commonly adopted surgical approach in 81% of centres (139), followed by thoracotomy in 67% (115) and RATS in 36% (62); 39% spent their training time on robotic simulator for training, 51% on robotic wet/dry lab, which being no significantly different to 46-59% who had training on VATS platform. There was indeed huge overlap between simulator models or varieties usage; 52% (90) reported of robotic surgery not a part of training curriculum with no plans to introduce it in future. Overall, 51.5% (89) responded of VATS experience being helpful in robotic training in view of familiarity with minimally invasive surgery anatomical views and dissection; 71% (124) reported that future thoracic surgeons should be proficient in both VATS and RATS. Half of the respondents found no difference in earlier chest drain removal with either approach (90), 35% (60) reported no difference in postoperative pain and 49% (84) found no difference in hospital stay; 52% (90) observed better lymph node harvest by RATS. Survey concluded on a positive response with at least 71% (123) surgeons recommending to adopt robotics in future.

920 Regular Formal Surgical Skills Training for Undergraduates - an Easy Way to Increase Enthusiasm for Postgraduate Surgical Training?

Abstract Aim Despite the publication of a clearly defined surgical curriculum by the Royal College of Surgeons of England, the availability of surgical training opportunities at medical school remains highly variable [1]. While one-off training days can increase students’ surgical skills confidence, we wanted to explore the effect of a regular skills course on students’ skills confidence, and the effect this had on their willingness to attend theatre lists and purse surgical training after graduation. Method We designed a 6-session training program covering the Basic Surgical Skills curriculum produced by the RCS. It also included robotic surgery simulation. The course was run twice due to high demand for places. Core trainees were recruited to help supervise the course. The course was sponsored by both ASiT and Medtronic and was free for attendees. Results The course received excellent feedback. Free text sections highlighted how regular skills training allowed for consolidating learning. Attendees were significantly more likely to feel confident in performing all the techniques covered after the course (Chi Squared, p < 0.05). 16/17 attendees (94.1%) candidates agreed that the course filled a gap in what teaching is provided by the medical school, and all attendees felt more confident attending theatre lists after attending the course. Of note, most students agreed the course had increased their inclination towards a surgical career (12/17 70.2%.). Conclusions The course highlights the importance of regular surgical skills teaching. It also highlights an important knock-on effect of making students more confident attending lists, and more likely to pursue surgical careers.

Home practice for robotic surgery: a randomized controlled trial of a low-cost simulation model

Pre-operative simulated practice allows trainees to learn robotic surgery outside the operating room without risking patient safety. While simulation practice has shown efficacy, simulators are expensive and frequently inaccessible. Cruff (J Surg Educ 78(2): 379–381, 2021) described a low-cost simulation model to learn hand movements for robotic surgery. Our study evaluates whether practice with low-cost home simulation models can improve trainee performance on robotic surgery simulators. Home simulation kits were adapted from those described by Cruff (J Surg Educ 78(2): 379–381, 2021). Hand controllers were modified to mimic the master tool manipulators (MTMs) on the da Vinci Skills Simulator (dVSS). Medical students completed two da Vinci exercises: Sea Spikes 1 (SS1) and Big Dipper Needle Driving (BDND). They were subsequently assigned to either receive a home simulation kit or not. Students returned two weeks later and repeated SS1 and BDND. Overall score, economy of motion, time to completion, and penalty subtotal were collected, and analyses of covariance were performed. Semi-structured interviews assessed student perceptions of the robotic simulation experience. Thirty-three medical students entered the study. Twenty-nine completed both sessions. The difference in score improvement between the experimental and control groups was not significant. In interviews, students provided suggestions to increase fidelity and usefulness of low-cost robotic home simulation. Low-cost home simulation models did not improve student performance on dVSS after two weeks of at-home practice. Interview data highlighted areas to focus future simulation efforts. Ongoing work is necessary to develop low-cost solutions to facilitate practice for robotic surgery and foster more inclusive and accessible surgical education.

Simulation-based education in urology - an update.

Over the past 30 years surgical training, including urology training, has changed from the Halstedian apprenticeship-based model to a competency-based one. Simulation-based education (SBE) is an effective, competency-based method for acquiring both technical and non-technical surgical skills and has rapidly become an essential component of urological education. This article introduces the key learning theory underpinning surgical education and SBE, discussing the educational concepts of mastery learning, deliberate practice, feedback, fidelity and assessment. These concepts are fundamental aspects of urological education, thus requiring clinical educators to have a detailed understanding of their impact on learning to assist trainees to acquire surgical skills. The article will then address in detail the current and emerging simulation modalities used in urological education, with specific urological examples provided. These modalities are part-task trainers and 3D-printed models for open surgery, laparoscopic bench and virtual reality trainers, robotic surgery simulation, simulated patients and roleplay, scenario-based simulation, hybrid simulation, distributed simulation and digital simulation. This article will particularly focus on recent advancements in several emerging simulation modalities that are being applied in urology training such as operable 3D-printed models, robotic surgery simulation and online simulation. The implementation of simulation into training programmes and our recommendations for the future direction of urological simulation will also be discussed.

Evaluation of a 3D-Printed Transoral Robotic Surgery Simulator Utilizing Artificial Tissue.

Transoral robotic surgery (TORS) poses challenges for operators in training, with limited robot access on a platform requiring distinct surgical skills. Few simulators exist, and current virtual reality training modules exclude head and neck simulations. This study evaluates the construct validity for a novel low-cost TORS simulator. Single institution prospective observational study. Using 3D-printed oral cavity structures and replaceable artificial tissue components, a modular TORS simulator was constructed for short-duration hands-on simulations with the da Vinci SI robot. Sixteen surgeons of differing robotic skill levels, no experience (novice), prior experience, and formal robot training, participated in simulated tonsil and tongue base tumor resections. Video recordings of each participant were graded by a blinded robotically trained surgeon using a 35-point Global Evaluative Assessment of Robotic Surgery (GEARS) criterion adapted for the TORS simulator. Operators reporting formal robotic training or prior robot experience achieved significantly higher mean total GEARS scores compared to novice operators (32 vs. 20.5; P < .001). Overall, mean total GEARS scores correlated with reported experience level; novice operators scored 54% of total points at 19 (4.5), operators with prior experience scored 82.3% of total points at 28.8 (2.6), and robotically trained operators scored 97.1% of total points at 34 (1.7). With a GEARS criterion, our simulator successfully differentiated novice from experienced and robotically trained operators of the da Vinci SI robot during simulated tonsillectomy and base of tongue resections. These findings support the construct validity of this prototype simulator and offer a foundation for further testing of predictive validity. 2 Laryngoscope, 132:1588-1593, 2022.

Gamification has been shown to be effective in improving medical training and has potential to increase resident engagement in robotic surgical simulation, as a means of achieving proficiency and growth. METHODS: We created a urology resident surgical simulation league composed of four teams, with each team coached by an attending urologist. The teams competed against one another in six rounds of head-to-head matchups. Each round, the residents were assigned three simulation exercises to complete using the da Vinci Skills Simulator (Intuitive, Sunnyvale, CA), which were scored from 0-100. At the end of the season, we sent an anonymous survey to the residents with questions about their experience with robotic surgery and simulation. Exercise scores and survey responses were used to assess engagement, proficiency, and growth. RESULTS: Fifteen urology residents participated in the simulation league and 14 completed the survey. Prior to the league, 36% had never used the simulator. During the league, 87% of residents completed at least 3 of the 6 rounds, and a total of 196/270 (73%) exercises were completed. Estimated monthly simulation time increased by 3,050%, compared to simulation time prior to the league. Scores above 90 were achieved on 93% of exercises, and perfect scores were achieved on 41% of exercises. Residents completed each assigned exercise a median of 8 times (IQR 5-14), and median improvement for each exercise was 19 points (IQR 7-48). As a result of the league, 57% of residents reported that their confidence in robotic surgery “moderately increased” or “greatly increased,” and 80% of residents who had used the robot in the operating room reported achieving more surgical autonomy since participating in the league. Following the league, 64% of residents anticipated that they would use the simulator more than they had prior to the league. CONCLUSIONS: Gamification led to a massive increase in resident engagement with surgical simulation, with high levels of improvement and proficiency in simulation exercises. This translated to increased confidence in robotic surgical skills, autonomy in the operating room, and interest in further training with robotic simulation.

Is laparoscopic experience helpful in simulator based robotic training in general surgery?

To evaluate whether or not prior laparoscopic training improves performance during robotic surgery utilising DaVinci robotic skills simulator. The cross-sectional study was conducted at the Civil Hospital, Karachi, from May 4 to November 11, 2018, and comprised first year residents in Group A with no laparoscopic skills and fourth year residents doing laparoscopic cholecystectomy independently and surgical faculty members in Group B who had laparoscopic skills. Both the groups had no previous exposure to robotic surgery and skills simulator. There were 4 exercises which were repeated three times by each participant. Scoring was done using the DaVinci robotic skills simulator software. Data was analysed using SPSS 22. Of the 30 surgeons, there were 15(50%) in Group A with a mean age of 26±0.56 years, and 15(50%) in Group B with a mean age of 32 ± 9.16 Years (p<0.001). The overall mean age was 32±9.16 years (range: 25-52 years). There were 19(63.3) females in the sample compared to 11(36.6%) males. Mean scores of Ring walk 2, Peg board 2, and Suture sponge 3 were better in Group A, while mean score of Matchboard 2 was better in Group although B (p>0.05). Group B fared better in the individual scoring of Suture sponge 2 (p>0.05). Laparoscopic skills apparently did not confer any benefit while performing exercises on the DaVinci skills simulator.

Impact of Acoustic and Interactive Disruptive Factors during Robot-Assisted Surgery-A Virtual Surgical Training Model.

The use of virtual reality trainers for teaching minimally invasive surgical techniques has been established for a long time in conventional laparoscopy as well as robotic surgery. The aim of the present study was to evaluate the impact of reproducible disruptive factors on the surgeon’s work. In a cross-sectional investigation, surgeons were tested with regard to the impact of different disruptive factors when doing exercises on a robotic-surgery simulator (Mimic Flex VRTM). Additionally, we collected data about the participants’ professional experience, gender, age, expertise in playing an instrument, and expertise in playing video games. The data were collected during DRUS 2019 (Symposium of the German Society for Robot-assisted Urology). Forty-two surgeons attending DRUS 2019 were asked to participate in a virtual robotic stress training unit. The surgeons worked in various specialties (visceral surgery, gynecology, and urology) and had different levels of expertise. The time taken to complete the exercise (TTCE), the final score (FSC), and blood loss (BL) were measured. In the basic exercise with an interactive disruption, TTCE was significantly longer (p < 0.01) and FSC significantly lower (p < 0.05). No significant difference in TTCE, FSC, or BL was noted in the advanced exercise with acoustic disruption. Performance during disruption was not dependent on the level of surgical experience, gender, age, expertise in playing an instrument, or playing video games. A positive correlation was registered between self-estimation and surgical experience. Interactive disruptions have a greater impact on the performance of a surgeon than acoustic ones. Disruption affects the performance of experienced as well as inexperienced surgeons. Disruption in daily surgery should be evaluated and minimized in the interest of the patient’s safety.

Design and Control of a 3 Degree-of-Freedom Parallel Passive Haptic Device.

Teleoperated robotic surgery and surgical simulation provide surgeons with tools that can improve the health outcomes of their patients. The limiting factor in many of these systems, however, is the lack of a haptic system that can render high impedance without compromising transparency or stability. To address this issue, we constructed a 3-Degree-of-Freedom haptic device using brakes as actuators. A novel controller is also proposed to increase the range of forces the device can generate and eliminate stiction. The device uses a modified Delta kinematic structure making it light and rigid. Since brakes are intrinsically stable, the device safely generates a wide range of impedance making it well suited for many surgical applications. The novel controller attempts to minimize the sum of forces acting perpendicular to the virtual surface eliminating un-smooth force output and stiction characteristic to passive devices, while increasing the range of displayable forces. The controller was validated using six testing scenarios where it rendered contact with frictionless surfaces. When using the controller, the device rendered the desired surface without stiction. Since the controller successfully rendered complex geometry, it can also work in other applications, such as robotic surgery and surgical simulation.

Training novice robot surgeons: Proctoring provides same results as simulator-generated guidance.

To understand the influence of proctored guidance versus simulator generated guidance (SGG) on the acquisition dexterity skills in novice surgeons learning RAS (robot assisted surgery). Prospective non-blinded 3-arm randomised controlled trial (RTC). Exclusion criteria: previous experience in RAS or robotic surgery simulation. The participants were assigned to three different intervention groups and received a different form of guidance: (1) proctored guidance, (2) simulator generated guidance, (3) no guidance, during training on virtual reality (VR) simulator. All participants were asked to complete multiple questionnaires. The training was the same in all groups with the exception of the intervention part. Catharina Hospital Eindhoven, The Netherlands. A total of 70 Dutch medical students, PhD-students, and surgical residents were included in the study. The participants were randomly assigned to one of the three groups. Overall, all the participants showed a significant improvement in their dexterity skills after the training. There was no significant difference in the improvement of surgical skills between the three different intervention groups. The proctored guidance group reported a higher participant satisfaction compared to the simulator-generated guidance group, which could indicate a higher motivation to continue the training. This study showed that novice surgeons. Significantly increase their dexterity skills in RAS after a short time of practicing on simulator. The lack of difference in results between the intervention groups could indicate there is a limited impact of "human proctoring" on dexterity skills during surgical simulation training. Since there is no difference between the intervention groups the exposure alone of novice surgeons to the robotic surgery simulator could possibly be sufficient to achieve a significant improvement of dexterity skills during the initial steps of RAS learning.

Does sleep deprivation alter virtual reality-based robotic surgical skills?

IntroductionRobotic surgery is widely used in many surgical specialities, and there has been no study to assess the impact of sleep deprivation on the complex environment of robotic surgery.AimTo compare specific metrics of selected robotic simulator exercises on sleep-deprived and non-sleep-deprived surgical residents.Material and methodsWe enrolled 20 volunteers, residents in surgery, evaluated before and after an 18-hour overnight shift, regarding their results on virtual robotic surgery simulator – the sleep deprivation (SD) group. As a control group, the same subjects were evaluated 5–7 days after the post-shift evaluation, without having a shift overnight and at least 7 h of sleep the previous night – the non-sleep-deprivation (nSD) group.ResultsA statistically significant difference between the pre-shift and post-shift overall results for all exercises in the SD group and no statistical differences for the nSD group were observed. As the difficulty of the exercises increased, statistical differences were observed on specific metrics for all exercises between the pre-shift and post-shift as well as between the post-shift and the morning after a normal sleep period overnight. In a subgroup analysis, the overall results revealed a stronger statistical difference between pre-shift and post-shift for residents with more intense sleep deprivation (< 3 h of sleep vs. > 3 h of sleep).ConclusionsSleep deprivation leads to impairment of surgical skills assessed by robotic virtual simulator. The more complex and skill demanding the exercise, the higher the difference between sleep deprived and non-deprived residents.

The use of LEGO Mindstorms to create a model of the surgical robot arm for the education of medical students

Abstract The aim of the work is to assess the use of LEGO-based robotics in the education of medical students. Training on specialized robotic surgery simulators is available only to a small group of specialists. The LEGO Mindstorms was used to create a model of the surgical robot arm. The model is controlled by a specially prepared panel created in the LabVIEW. The functionality of the model of a surgical robot arm allows people who have not been using these robots to become familiar with the basics of their operation. Medical students using the arm will be able to observe structural problems: the stiffness of construction, or its utility, the range of movements and its limitations, motion and force control using different robotic manipulators. The use of a modular computer programming language and a modular building platform problem in LEGO Education contributes to the development of critical thinking and problem solving, and these skills are useful to physicians during their work.

Does previous open surgical experience have any influence on robotic surgery simulation exercises?

IntroductionWithin the last years, there has been a trend in many hospitals to switch their surgical activity from open/laparoscopic procedures to robotic surgery. Some open surgeons have been shifting their activity to robotic surgery. It is still unclear whether there is a transfer of open surgical skills to robotic ones.AimTo evaluate whether such transfer of skills occurs and to identify which specific skills are more significantly transferred from the operative table to the console.Material and methodsTwenty-five volunteers were included in the study, divided into 2 groups: group A (15 participants) – medical students (without any surgical experience in open, laparoscopic or robotic surgery); and group B (10 participants) – surgeons with exclusively open surgical experience, without any previous laparoscopic or robotic experience. Participants were asked to complete 3 robotic simulator console exercises structured from the easiest one (Peg Board) to the toughest one (Sponge Suture). Overall scores for each exercise as well as specific metrics were compared between the two groups.ResultsThere were no significant differences between overall scores of the two groups for the easiest task. Overall scores were better for group B as the exercises got more complex. For the intermediate and high-difficulty level exercises, most of the specific metrics were better for group B, with the exception of the working master space item.ConclusionsOur results suggest that the open surgical skills transfer to robotic skills, at least for the very beginning of the training process.
