Training and learning robotic surgery, time for a more structured approach: a systematic review

Understanding the challenges of robotic-assisted surgery adoption: Perspectives from stakeholders and the general population on human-interaction, built environment, and training

This study aims to explore adoption barriers from three aspects critical to facilitating robotic-assisted-surgery (RAS) adoption: the human-robot-interaction, built-environment, and training. Guidelines for research and design are identified from these perspectives. This study consisted of three phases: 1) surveys to RAS stakeholders and a crowd-sourcing survey; 2) stakeholder focus groups; and 3) a workshop with subject-matter experts to prioritize future research for RAS. Barriers from the human-robot-interaction perspective include hesitancy among clinicians to trust automation and physical discomfort during prolonged RAS. Barriers impeding communication and workflow disruptions were identified considering the built-environment. Training barriers were exemplified by varying curriculums from formal (courses) to informal (peer training) for surgeons. Crowd-sourced survey results suggest socio-economic status plays a role in RAS perception. Design guidelines include: 1) improved ergonomics; 2) deliberate introduction of automation; 3) sufficient in-room storage for prospective operating rooms; and 4) the development of compact RAS devices for older/smaller rooms.

Consensus guidelines on the bedside assistant skills required in robotic surgery

BACKGROUND

While bedside assistants play a critical role in many robotic operations, substantial heterogeneity remains in bedside assistant training pathways. As such, this study aimed to develop consensus guidelines for bedside assistant skills required for team members in robotic operations.

METHODS

We designed a study using the Delphi process to develop consensus guidelines around bedside assistant skills. We generated an initial list of bedside assistant skills from the literature, training materials, and expert input. We selected experts for the Delphi process based on prior scholarship in the area of robotic bedside assistant education and experience facilitating robotic bedside assistant training. For each item, respondents specified which robotic team members should have the skill from a list of "basic" bedside assistants, "advanced" bedside assistants, surgeons, surgical technologists, and circulating nurses. We conducted two rounds of the Delphi process and defined 80% agreement as sufficient for consensus.

RESULTS

Fourteen experts participated in two rounds of the Delphi process. By the end of the second round, the group had reached consensus on 253 of 305 items (83%). The group determined that "basic" bedside assistants should have 52 skills and that "advanced" bedside assistants should have 60 skills. The group also determined that surgeons should have 54 skills, surgical technologists should have 25 skills, and circulating nurses should have 17 skills. Experts agreed that all participants should have certain communication skills and basic knowledge of aspects of the robotic system.

CONCLUSIONS

We developed consensus guidelines on the skills required during robotic surgery by bedside assistants and other team members using the Delphi process. These findings can be used to design training around bedside assistant skills and assess team members to ensure that each team member has the appropriate skills. Hospitals can also use these guidelines to standardize expectations for robotic team members.

Learning curve in robotic liver surgery: easily achievable, evolving from laparoscopic background and team-based

BACKGROUND

Limited and heterogeneous literature data necessitate a focused examination of the learning curve in robotic liver resections. This study aims to assess the learning curve of two surgeons from the same team with differing laparoscopic backgrounds.

METHODS

Since February 2021, San Raffaele Hospital in Milan has implemented a robotic liver surgery program, performing 250 resections by three trained console surgeons. Using cumulative sum (CUSUM) analysis, the learning curve was evaluated for a Pioneer Surgeon (PS) with around 1200 laparoscopic cases and a New Generation Surgeon (NGS) with approximately 100 laparoscopic cases. Cases were stratified by complexity (38 low, 74 intermediate, 85 high).

RESULTS

Both PS and NGS demonstrated a learning curve for operative time after 15 low-complexity and 10 intermediate-complexity cases, with high-complexity learning curves apparent after 10 cases for PS and 18 cases for NGS. Conversion rates remained unaffected, and neither surgeon experienced increased blood loss or postoperative complications. A "team learning curve" effect in terms of operative time emerged after 12 cases, suggesting the importance of a cohesive surgical team.

CONCLUSION

The robotic platform facilitated a relatively brief learning curve for low and intermediate complexity cases, irrespective of laparoscopic background, underscoring the benefits of team collaboration.

Comparative Efficacy and Safety of Robot-Assisted vs. Freehand Screw Placement in Femoral Neck Fractures: An Updated Systematic Review and Meta-Analysis

Background: Femoral neck fractures pose significant surgical challenges with high morbidity and mortality. Traditional freehand screw placement often yields variable outcomes. Recent robotic advancements offer a promising alternative with enhanced precision. Methods: This systematic review compares the efficacy and safety of robot-assisted versus freehand techniques. A comprehensive literature search across multiple databases up to July 2024 included studies comparing both techniques. Primary outcomes were the union rate and time, functional outcomes, operative time, intraoperative parameters, and complication rates. Meta-regression analyses identified treatment response determinants. Results: Twenty-four studies (1437 patients) were included. Robot-assisted screw placement significantly improved the union rate, reduced the union time, and showed superior functional outcomes. Additionally, it resulted in shorter operative times, less intraoperative blood loss, and fewer instances of fluoroscopy and guide pin insertion. The risk of femoral neck necrosis was notably lower with robotic assistance. Meta-regression highlighted the robot type, patient age, and sample size as significant factors. Conclusions: Despite the promise of robot-assisted screw placement, limitations exist. The evidence being mainly from China raises concerns about generalizability. The lack of long-term follow-up data hinders assessment of technique durability. Unreported surgeon expertise levels and learning curves affect result validity. High initial costs and steep learning curves of robotic systems also present barriers to widespread adoption.

Introducing a novice surgeon to an experienced robotic gynaecological oncology team: An observational cohort study on the impact of a structured curriculum on outcomes of cervical cancer surgery

OBJECTIVE

To evaluate the effect on patient outcomes when introducing a novice robotic surgeon, trained in accordance with a structured learning curriculum, to an experienced robotic surgery team treating cervical cancer patients.

METHODS

Patients with early-stage cervical cancer who were treated with primary robot-assisted surgery between 2007 and 2019 were retrospectively included. In addition to the 165 patients included in a former analysis, we included a further 61 consecutively treated patients and divided all 226 patients over three groups: early learning phase of 61 procedures without structured training (group 1), experienced phase of 104 procedures (group 2), and the 61 procedures during introduction of a novice with structured training (group 3). Risk-adjusted cumulative sum (RA-CUSUM) analysis was performed to assess the learning curve effect. Patient outcomes between the groups were compared.

RESULTS

Based on RA-CUSUM analysis, no learning curve effect was observed for group 3. Regarding surgical outcomes, mean operation time in group 3 was significantly shorter than group 1 (p < 0.001) and similar to group 2 (p = 0.96). Proportions of intraoperative and postoperative adverse events in group 3 were not significantly different from the experienced group (group 2). Regarding oncological outcomes, the 5-year disease-free survival, disease-specific survival, and overall survival in group 3 were not significantly different from the experienced group.

CONCLUSIONS

Introducing a novice robotic surgeon, who was trained in accordance with a structured learning curriculum, resulted in similar patient outcomes as by experienced surgeons suggesting novices can progress through a learning phase without compromising outcomes of cervical cancer patients.

Open, Laparoscopic, and Robotic Approaches to Treat Colorectal Cancer: A Comprehensive Review of Literature

Surgery is usually required to treat colorectal cancer (CRC). Medical technology has advanced, providing various approaches to tackle this disease. Different surgeries are available, such as laparoscopic surgery, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and robotic surgery. Laparoscopic surgery has several benefits including reduced blood loss and shorter recovery time. It can also improve lung function and minimize complications. However, it requires more time to perform and has a higher risk of complications during the procedure. Robotic surgery provides a three-dimensional view of the surgical area allowing for greater precision in rectal surgeries and access to difficult-to-reach pelvic regions. This method utilizes robotics technology which reduces surgical time and speeds up recovery for patients. There are various surgical options available for treating CRC; however, laparoscopic surgery and robotic surgery offer unique advantages despite their own drawbacks. As technology continues to evolve, medical techniques will continue improving existing methods while providing new options resulting in better outcomes for patients. Compared to laparoscopy, robotic surgery has a lower rate of operative conversions and a shorter learning curve. However, it also has some drawbacks, such as a longer docking time, lack of tactile sensation, and higher cost. Therefore, the choice of surgical method should depend on patient characteristics, surgeon preference and expertise, and available resources. Currently, specialized centers offer robotic surgeries which are more expensive and take longer compared to open and laparoscopic approaches. Nonetheless, they are considered safe and feasible when compared to traditional surgery. Short-term outcomes for robotic surgeries are better, while long-term postoperative complication rates remain similar. However, there is a need for additional well-defined randomized control trials conducted across multiple centers to validate the use of robotic surgery over open and laparoscopic approaches. Improving patient care and outcomes is the objective of this comprehensive literature overview on surgical approaches for CRC.

Force-based assessment of tissue handling skills in simulation training for robot-assisted surgery

INTRODUCTION

Although robotic-assisted surgery is increasingly performed, objective assessment of technical skills is lacking. The aim of this study is to provide validity evidence for objective assessment of technical skills for robotic-assisted surgery.

METHODS

An international multicenter study was conducted with participants from the academic hospitals Heidelberg University Hospital (Germany, Heidelberg) and the Amsterdam University Medical Centers (The Netherlands, Amsterdam). Trainees with distinctly different levels of robotic surgery experience were divided into three groups (novice, intermediate, expert) and enrolled in a training curriculum. Each trainee performed six trials of a standardized suturing task using the da Vinci Surgical System. Using the ForceSense system, five force-based parameters were analyzed, for objective assessment of tissue handling skills. Mann-Whitney U test and linear regression were used to analyze performance differences and the Wilcoxon signed-rank test to analyze skills progression.

RESULTS

A total of 360 trials, performed by 60 participants, were analyzed. Significant differences between the novices, intermediates and experts were observed regarding the total completion time (41 s vs 29 s vs 22 s p = 0.003), mean non zero force (29 N vs 33 N vs 19 N p = 0.032), maximum impulse (40 Ns vs 31 Ns vs 20 Ns p = 0.001) and force volume (38 N³ vs 32 N³ vs 22 N³ p = 0.018). Furthermore, the experts showed better results in mean non-zero force (22 N vs 13 N p = 0.015), maximum impulse (24 Ns vs 17 Ns p = 0.043) and force volume (25 N³ vs 16 N³ p = 0.025) compared to the intermediates (p ≤ 0.05). Lastly, learning curve improvement was observed for the total task completion time, mean non-zero force, maximum impulse and force volume (p ≤ 0.05).

CONCLUSION

Construct validity for force-based assessment of tissue handling skills in robot-assisted surgery is established. It is advised to incorporate objective assessment and feedback in robot-assisted surgery training programs to determine technical proficiency and, potentially, to prevent tissue trauma.

Development of an affordable, immersive model for robotic vaginal cuff closure: a randomized trial

Safe and secure closure of the vaginal cuff is a critical component of a robotic assisted hysterectomy procedure. Our aim in this study is to develop and validate a novel vaginal cuff closure model (VC) created from porcine heart that allows trainees to obtain competency in a low-risk environment. Ten expert and 20 novice robotic surgeons performed a cuff closure exercise on the VC model and on the dV-Trainer^®, a virtual reality simulator (VR). Performances were timed, videotaped, and scored using the modified Global Evaluative Assessment of Robotic Skills (mGEARS) score. Expert robotic surgeons completed the task faster on both the VR (531 vs. 814 s, p = 0.03) and the VC platforms (311 vs. 631 s, p < 0.001) and achieved higher mGEAR scores (32.25 vs. 22.07, p < 0.0001). Knot quality and suturing accuracy were better in the VC than in the VR environment in both groups. In a post-completion survey, both expert and novice surgeons expressed strong preference towards the VC model. In this study, the novel VC model proved to be a reliable simulation tool with high face, content, and construct validity. Due to its simplicity and low cost, this high-yield simulation exercise can easily be incorporated into robotic training curricula of obstetrics and gynecology residents.

[Robotic sleeve gastrectomy: single-center experience]

OBJECTIVE

To demonstrate safe introduction of a new technology (Da Vinci robotic system) into laparoscopic bariatric practice.

MATERIAL AND METHODS

We analyzed treatment outcomes in patients with morbid obesity who underwent robot-assisted sleeve gastrectomy between 2020 and 2023. The same team of surgeons performed all operations. Evolution of technique and preparation of the operating theatre were recorded. Demographic data of patients, surgery time (docking and total surgery time), simultaneity of intervention, intraoperative and postoperative complications, as well as weight loss after 6 months were retrospectively analyzed.

RESULTS

There were 15 robot-assisted sleeve gastrectomies between 2020 and 2023. Of these, 14 patients underwent surgery without complications. One patient was diagnosed with portal vein thrombosis that required anticoagulation. Median surgery time 194 [173.5; 241] min, period between incision and docking - 35 [30; 36] min. The length of hospital-stay was 3 days. The median weight loss after 6 months was 37.5% [29.5; 51.2].

CONCLUSION

This study demonstrates safe introduction of a new technology to prepare the bariatric team for more complex surgical interventions in the future.

Multidisciplinary perceptions on robotic surgical training: the robot is a stimulus for surgical education change

BACKGROUND

It is unclear how to best establish successful robotic training programs or if subspecialty robotic program principles can be adapted for general surgery practice. The objective of this study is to understand the perspectives of high-volume robotic surgical educators on best practices in robotic surgery training and to provide recommendations transferable across surgical disciplines.

METHODS

This multi-institutional qualitative analysis involved semi-structured interviews with high-volume robotic educators from academic general surgery (AGS), community general surgery (CGS), urology (URO), and gynecology (GYN). Purposeful sampling and snowballing ensured high-volume status and geographically balanced representation across four strata. Interviews were transcribed, deidentified, and independently, inductively coded. A codebook was developed and refined using constant comparative method until interrater reliability kappa reached 0.95. A qualitative thematic, framework analysis was completed.

RESULTS

Thirty-four interviews were completed: AGS (n = 9), CGS (n = 8), URO (n = 9), and GYN (n = 8) resulting in 40 codes and four themes. Theme 1: intangibles of culture, resident engagement, and faculty and administrative buy-in are as important as tangibles of robot and simulator access, online modules, and case volumes. Theme 2: robotic OR integration stresses the trainee-autonomy versus patient-safety balance. Theme 3: trainees acquire robotic skills along individual learning curves; benchmark assessments track progress. Theme 4: AGS can learn from URO and GYN through multidisciplinary collaboration but must balance pre-existing training program use with context-specific curricular needs.

CONCLUSIONS

Robotic surgical experts emphasize the importance of universal training paradigms, such as a strong educational culture that balances autonomy and patient safety, collaboration between disciplines, and routine assessments for continuous growth. Often, introduction and acceptance of the robot serves as a stimulus to discuss broader surgical education change.

A Comparative Analysis of Short-term Patient Outcomes After Laparoscopic Versus Robotic Rectal Surgery

BACKGROUND

The popularity of robot-assisted colorectal surgery has risen over recent years; however, patient-related advantages over laparoscopic surgery remain uncertain.

OBJECTIVE

The goal of this study was to compare short-term patient outcomes following robotic and laparoscopic partial or complete rectal resections.

DESIGN

This was a retrospective cohort study.

SETTINGS

The study was conducted at 5 large tertiary care Kaiser Permanente medical centers across Southern California.

PATIENTS

There were 863 consecutive robotic and laparoscopic pelvic rectal surgeries, including low anterior resections, proctectomies with coloanal anastomosis, and abdominoperineal resections, performed between January 2010 and December 2019.

MAIN OUTCOME MEASURES

Short-term patient outcomes, including postoperative length of hospital stay, emergency department returns, and 30-day readmissions, and mortality.

RESULTS

A total of 458 surgical procedures were performed via robotic versus 405 via laparoscopic approaches. The robotic group had a higher proportion of male patients (57.4% vs 50.4%; p = 0.04) and a higher proportion of obese (27.1% vs 26.9%; p = 0.02) and overweight patients (36.9% vs 35.1%; p = 0.01). There was no difference in underlying comorbidities of diabetes or smoking, or in the rate of ileostomy creation. After adjusting for Charlson Comorbidity Index, no significant difference was found in emergency department returns between robotic and laparoscopic surgical patients ( p = 0.17). There were no significant outcome differences between the 2 groups with regards to length of stay during procedure, 30-day readmission, or death rates.

LIMITATIONS

This study was limited by the lack of randomization in its design, selection of patients for surgical approach, and training and familiarity with robotic rectal surgery.

CONCLUSIONS

This study shows length of stay during the procedure and postoperative 30-day readmission rates were generally similar between robotic and laparoscopic patients. Male patients and those with a higher BMI were more likely to have been operated via a robotic method. See Video Abstract at http://links.lww.com/DCR/B857 .

Value-assessment of computer-assisted navigation strategies during percutaneous needle placement

Purpose

Navigational strategies create a scenario whereby percutaneous needle-based interventions of the liver can be guided using both pre-interventional 3D imaging datasets and dynamic interventional ultrasound (US). To score how such technologies impact the needle placement process, we performed kinematic analysis on different user groups.

Methods

Using a custom biopsy phantom, three consecutive exercises were performed by both novices and experts (n = 26). The exercise came in three options: (1) US-guidance, (2) US-guidance with pre-interventional image-registration (US + Reg) and (3) US-guidance with pre-interventional image-registration and needle-navigation (US + Reg + Nav). The traveled paths of the needle were digitized in 3D. Using custom software algorithms, kinematic metrics were extracted and related to dexterity, decision making indices to obtain overall performance scores (PS).

Results

Kinematic analysis helped quantifying the visual assessment of the needle trajectories. Compared to US-guidance, novices yielded most improvements using Reg (PSavg(US) = 0.43 vs. PSavg(US+Reg) = 0.57 vs. PSavg(US+Reg+Nav) = 0.51). Interestingly, the expert group yielded a reversed trend (PSavg(US) = 0.71 vs PSavg(US+Reg) = 0.58 vs PSavg(US+Reg+Nav) = 0.59).

Conclusion

Digitizing the movement trajectory allowed us to objectively assess the impact of needle-navigation strategies on percutaneous procedures. In particular, our findings suggest that these advanced technologies have a positive impact on the kinematics derived performance of novices.

The Future in Standards of Care for Gynecologic Laparoscopic Surgery to Improve Training and Education

Standards of care offer doctors and patients the confidence that an established quality, evidence-based, care is provided, and represent a tool for optimal responding to the population’s needs. It is expected that they will increasingly express a multimodal relationship with gynecologic laparoscopy. Laparoscopy is, now, a standard procedure in operative gynecology, standards are embedded in many laparoscopic procedures, standardization of the skills/competency assessment has been progressively developed, and the proof of competency in laparoscopy may become a standard of care. A continuous development of surgical education includes standard equipment (that may bring value for future advance), standardized training, testing (and performance) assessment, educational process and outcome monitoring/evaluation, patients’ care, and protection, etc. Standards of care and training have a reciprocally sustaining relationship, as training is an essential component of standards of care while care is provided at higher standards after a structured training and as credentialing/certification reunites the two. It is envisaged that through development and implementation, the European wide standards of care in laparoscopic surgery (in close harmonization with personalized medicine) would lead to effective delivery of better clinical services and provide excellent training and education.

Anatomical Engineering and 3D Printing for Surgery and Medical Devices: International Review and Future Exponential Innovations

Three-dimensional printing (3DP) has recently gained importance in the medical industry, especially in surgical specialties. It uses different techniques and materials based on patients' needs, which allows bioprofessionals to design and develop unique pieces using medical imaging provided by computed tomography (CT) and magnetic resonance imaging (MRI). Therefore, the Department of Biology and Medicine and the Department of Physics and Engineering, at the Bioastronautics and Space Mechatronics Research Group, have managed and supervised an international cooperation study, in order to present a general review of the innovative surgical applications, focused on anatomical systems, such as the nervous and craniofacial system, cardiovascular system, digestive system, genitourinary system, and musculoskeletal system. Finally, the integration with augmented, mixed, virtual reality is analyzed to show the advantages of personalized treatments, taking into account the improvements for preoperative, intraoperative planning, and medical training. Also, this article explores the creation of devices and tools for space surgery to get better outcomes under changing gravity conditions.

Improving robotic skills by video review

Background Since the transition of surgical robot systems into the medical field, physicians have had to develop new dexterity skills. The ideal learning environment for robotic surgery has yet to be discovered. Virtual-reality (VR) simulation is a possible safe and economic method. In VR-simulator training human feedback is hardly used, an alternative may be found in video revision. The purpose of this study is to investigate whether adding video review to VR-simulation-based training in novice physicians improves their ability to complete a complex robot task. In addition, the secondary goal is to investigate whether the skills learned on the robotic simulator can be transferred to a real robotic system. Methods 40 participants, medical students and, medical-PhD candidates, from one university hospital, were included. Baseline dexterity skills were measured through completion of a vesico-urethral anastomosis on a VR-robot simulator and the DaVinci robot. Participants were randomized into a video and control group. The video group practiced skills on the robot simulator with intermediate video revision, whereas the control group had intermediate pause instead. Post-intervention dexterity skills were measured using the same exercises as the baseline tests. Results No significant differences were found in baseline performance. Post-intervention results on the VR-simulator show that the video group commits significantly fewer injuries to the urethra and sutures at a greater optimal depth. The control group was significantly faster, had less camera travel, and had their instruments less out of view. On the DaVinci robot, participants in both groups performed significantly faster and had better GEARS-score after the training sessions on the VR simulator. Conclusions Video revision significantly improves the quality of robotic skills in novice surgeons on the VR-simulator, though at the expense of time. Furthermore, both groups demonstrated enhanced skills on the DaVinci robot after training sessions, which advocates the transferability of skill.

Training and credentialing in Robotic Surgery in India: Current perspectives

Robotic surgery has changed the landscape of surgery and ushered in a new era of technology-assisted minimally invasive surgery. There is a paradigm shift from traditional open surgeries to minimal access surgery, with robotic surgery being the new standard of care in some surgical fields. This change comes with an unprecedented influx of innovations in technology related to minimal access surgery, robotics and artificial intelligence. Despite the exponential advances in technology, there is a lacuna in the training and credentialling of robotic surgeons. In India, no dedicated training curriculum exists for trainees in robotic surgery. Thus, as robotic surgery continues to develop in India, it is imperative that robust training and credentialing systems are in place to ensure that patient safety and surgical outcomes are not compromised.

Lack of residents due to COVID-19 pandemic. Can a mentor–mentee program during medical studies have a positive influence on the choice for specialist training in gynecology and obstetrics? A review of current literature and results of a national wide survey of medical students

Objective

The COVID-19 pandemic restricting clinical practice and exacerbating the lack of medical staff. There is currently a lack of young residents who are deciding on further training in gynecology and obstetrics. Design: review and prospective, cross-sectional study. Setting: the aim of this study was to investigate if structured mentoring programs can counteract this deficiency. Population: medical students took part from Germany in the clinical phase.

Methods

An anonymous questionnaire was developed and distributed to students from January to October 2020. Epidemiological data, questions about mentoring experiences, necessity and their expected influence on career planning were collected and statistically evaluated. Main outcome measures: structured mentoring-programs can influence the choice of subject. In particular, men are still underrepresented. Research on the topic of mentoring during in the field of gynaecology and obstetrics is completely lacking.

Results

A representative number of 927 medical students took part in the survey. 22% (170/906) of the students had already participated in a mentoring program with a significantly higher proportion of men (69%; 117/170; p < 0.001). Of these, 94% (453/170) said this was helpful. 6% (55/906) wanted to pursue a career in gynecology and obstetrics. When asked about their appreciation for structured mentoring programs in gynecology and obstetrics, 95% (880/906) would participate and 94% agreed (871/906) that this could have an impact on their choice of specialist and career planning.

Conclusions

An active provision of mentoring programs and more content can be a way of counteracting the shortage of residents in gynecology and obstetrics.

A review of robotic surgical training: establishing a curriculum and credentialing process in ophthalmology

Ophthalmic surgery requires a highly dexterous and precise surgical approach to work within the small confines of the eye, and the use of robotics offers numerous potential advantages to current surgical techniques. However, there is a lag in the development of a comprehensive training and credentialing system for robotic eye surgery, and certification of robotic skills proficiency relies heavily on industry leadership. We conducted a literature review on the curricular elements of established robotics training programs as well as privileging guidelines from various institutions to outline key components in training and credentialing robotic surgeons for ophthalmic surgeries. Based on our literature review and informal discussions between the authors and other robotic ophthalmic experts, we recommend that the overall training framework for robotic ophthalmic trainees proceeds in a stepwise, competency-based manner from didactic learning, to simulation exercises, to finally operative experiences. Nontechnical skills such as device troubleshooting and interprofessional teamwork should also be formally taught and evaluated. In addition, we have developed an assessment tool based on validated global rating scales for surgical skills that may be used to monitor the progress of trainees. Finally, we propose a graduating model for granting privileges to robotic surgeons. Further work will need to be undertaken to assess the feasibility, efficacy and integrity of the training curriculum and credentialing practices for robotic ophthalmic surgery.

Identifying curriculum content for a cross-specialty robotic-assisted surgery training program: a Delphi study

BACKGROUND

Robotic-assisted surgery is increasing and there is a need for a structured and evidence-based curriculum to learn basic robotic competencies. Relevant training tasks, eligible trainees, realistic learning goals, and suitable training methods must be identified. We sought to develop a common curriculum that can ensure basic competencies across specialties.

METHODS

Two robotic surgeons from all departments in Denmark conducting robotic-assisted surgery within gynecology, urology, and gastrointestinal surgery, were invited to participate in a three-round Delphi study to identify learning goals and rank them according to relevance for a basic curriculum. An additional survey was conducted after the Delphi rounds on what training methods were considered best for each learning goal and who (console surgeon/patient-side assistant) should master each learning goal.

RESULTS

Fifty-six robotic surgeons participated and the response rates were 86%, 89%, and 77%, for rounds 1, 2 and 3, respectively. The Delphi study identified 40 potential learning goals, of which 29 were ranked as essential, e.g., Understand the link between arm placement and freedom of movement or Be able to perform emergency un-docking. In the additional survey, the response rate was 70%. Twenty-two (55%) of the identified learning goals were found relevant for the patient-side assistant and twenty-four (60%) were linked to a specific suitable learning method with > 75% agreement.

CONCLUSIONS

Our findings can help training centers plan their training programs concerning educational content and methods for training/learning. Furthermore, patient-side assistants should also receive basic skills training in robotic surgery.

Implementation of a standardized robotic assistant surgical training curriculum

Since 2000, robotic-assisted surgery has rapidly expanded into almost every surgical sub-specialty. Despite the popularity of robotic surgery across the United States, a national consensus for standardized training and education of robotic surgeons or surgical teams remains absent. In this quality improvement initiative, a novel, stepwise iterative Robotic Assistant Surgical Training (RAST) curriculum was developed to broaden and standardize robotic bedside assistant training. Thirteen voluntary participants, capable of fulfilling the bedside assistant role, were evaluated to determine if RAST enhanced the learner's self-perceived level of confidence and comfort in their role as bedside assistant. A pre- and post-RAST training survey and a between-stages repeated-measures survey were conducted. All learner participants reported statistically significant increases in confidence and comfort after RAST training, (p =  < 0.001), and between each stage, F (2, 24 = 60.47, p < .001; [Formula: see text] = 0.834). Participant feedback regarding curriculum improvement was obtained, suggesting the desire for more training and practice, in smaller groups of 2-3 participants. One hundred percent of participants felt RAST was beneficial and that it should be implemented as standardized training during onboarding for all robotic bedside assistants. Thus, a standardized, stepwise iterative robotic bedside assistant curriculum increases learner preparedness, comfort, and confidence, safely away from the patient bedside.

Learning curve of robot-assisted transabdominal preperitoneal (rTAPP) inguinal hernia repair: a cumulative sum (CUSUM) analysis

BACKGROUND

Robot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP-IHR) is a safe and feasible approach for hernias of varying etiology. We aim to present a single surgeon's learning curve (LC) of this technique based on operative times, while accounting for bilaterality and complexity.

METHODS

This is a retrospective cohort analysis of patients who underwent rTAPP-IHR over a period of 5 years. Patients who underwent primary, recurrent, and complex (previous posterior repair, previous prostatectomy, scrotal, incarcerated) repairs were included. Cumulative and risk-adjusted cumulative sum analyses (CUSUM and RA-CUSUM) were used to depict the evolution of skin-to-skin times and complications/surgical site events (SSEs) with time, respectively.

RESULTS

A total of 371 patients were included in the study. Mean skin-to-skin times were stratified according to four subgroups: unilateral non-complex (46.8 min), unilateral complex (63.2 min), bilateral non-complex (70.9 min), and bilateral complex (102 min). A CUSUM-LC was then plotted using each procedures difference in operative time from its subgroup mean. The peak of the plot occurred at case number 138, which was used as a transition between 'early' and 'late' phases. The average operative time for the late phase was 15.9 min shorter than the early phase (p < 0.001). The RA-CUSUM, plotted using the weight of case complexity and unilateral/bilateral status, also showed decreasing SSE rates after the completion of 138 cases (early phase: 8.8% vs. late phase: 2.2%, p = 0.008). Overall complication rates did not differ significantly between the two phases.

CONCLUSIONS

Our study shows that regardless of bilateral or complex status, rTAPP operative times and SSE rates gradually decreased after completing 138 procedures. Previous laparoscopic experience, robotic team efficiency, and surgical knowledge are important considerations for a surgeon's LC.

Teaching and learning robotic surgery at the dual console: a video-based qualitative analysis

Robotic-assisted surgery (RAS) involves training processes and challenges that differ from open or laparoscopic surgery, particularly regarding the possibilities of observation and embodied guidance. The video recording and the dual-console system creates a potential opportunity for participation. Our research, conducted within the department of visceral surgery of a big Swiss, public, academic hospital, uses a methodology based on the co-analysis of video recordings with surgeons in self-confrontation interviews, to investigate the teaching activity of the lead surgeon supervising a surgeon in training at the dual console. Three short sequences have been selected for the paper. Our analysis highlights the skills-in-construction of the surgeon in training regarding communication with the operating team, fluency of working with three hands, and awareness of the whole operating site. It also shows the divergent necessities of enabling verbalization for professional training, while ensuring a quiet and efficient environment for medical performance. To balance these requirements, we argue that dedicated briefing and debriefing sessions may be particularly effective; we also suggest that the self-confrontation video technique may be valuable to support the verbalization on both the mentor’s and the trainee’s side during such debriefing, and to enhance the mentor’s reflexivity regarding didactic choices.

The influence of learning curve of robot-assisted laparoscopy on oncological outcomes in early-stage cervical cancer: an observational cohort study

OBJECTIVE

To investigate the learning curve of robot-assisted laparoscopy in early-stage cervical cancer and quantify impact on oncological outcomes.

DESIGN

Observational cohort study.

SETTING

Tertiary referral centre with one surgical team.

POPULATION

All women with early-stage cervical cancer treated consecutively with robot-assisted laparoscopy between 2007 and 2017.

METHODS

With multivariate risk-adjusted cumulative sum analysis (RA-CUSUM), we assessed the learning curve of robot-assisted laparoscopy of a single surgical team based on cervical cancer recurrence. Subsequently, a survival analysis was conducted comparing oncological outcomes of women treated during different phases of the learning curve.

MAIN OUTCOME MEASURES

Surgical proficiency based on recurrence, survival rates in the different learning phases.

RESULTS

One hundred and sixty-five women with cervical cancer underwent robot-assisted laparoscopy, with a median follow up of 57 months (range 3-132 months). The RA-CUSUM analysis demonstrated two phases of the learning curve: a learning phase of 61 procedures (group 1) and an experienced phase representing the 104 procedures thereafter (group 2). The 5-year disease-free survival was 80.2% in group 1 and 91.1% in group 2 (P = 0.040). Both the 5-year disease-specific survival and overall survival significantly increased after the learning phase.

CONCLUSION

The learning phase of robot-assisted laparoscopy in early-stage cervical cancer in this institutional cohort is at least 61 procedures, with higher survival rates in the women treated thereafter. The learning curve of robot-assisted laparoscopy affects oncological outcomes and warrants more attention in the design of future studies.

TWEETABLE ABSTRACT

The learning curve of robot-assisted laparoscopy in early-stage cervical cancer affects oncological outcomes and warrants more attention.

Can video games enhance surgical skills acquisition for medical students? A systematic review

OBJECTIVE

To systematically assess literature examining the impact of being a gamer or participating in video-game-based training on surgical skills acquisition amongst medical students.

BACKGROUND

Video games and surgical procedures share similar skills such as visuospatial abilities and hand-eye coordination; therefore, video games can be a valuable tool for surgical training amongst medical students. However, comprehensive, up-to-date systematic reviews are necessary to confirm.

METHODS

A systematic literature search of PubMed, MEDLINE, and EMBASE was performed in April 2020 with no limits set on the date of publication. Observational and randomized controlled studies were included. Quality and bias were assessed using the Newcastle-Ottawa Scale for nonrandomized studies and the Grading of Recommendations Assessment, Development and Evaluation system for randomized studies.

RESULTS

A total of 575 participants from 16 studies were included. The most common surgical skills tested were laparoscopy (n = 283, from 8 studies) and robotic surgery (n = 199, from 5 studies). A history of gaming and video-game-based training were associated with improved metrics in robotic surgery and laparoscopy, respectively. Neither was beneficial in arthroscopy or bronchoscopy. Studies using the Wii U and Underground reported significant improvement in overall laparoscopic performance.

CONCLUSION

Video games demonstrate potential as adjunctive training in surgical skill education, with a history of gaming and video-game-based training being beneficial in robotic surgery and laparoscopy, respectively. Methodological heterogeneity amongst included studies limit the ability to make conclusive decisions; thus, future studies with long-term follow-up, larger sample sizes, outcomes stratified by video-game characteristics, and up-to-date technology are necessary.

Evolution of robotic-assisted kidney transplant: successes and barriers to overcome

PURPOSE OF REVIEW

The aim of this study was to provide an updated review of robotic-assisted kidney transplant (RAKT) with an emphasis on advantages over the open kidney transplant (OKT), utility in special populations and resources available to overcome the learning curve of robotic surgery.

RECENT FINDINGS

The majority of the reported studies showed that RAKT and OKT have similar functional outcomes including similar ischemia times and time to postoperative normalization of creatinine. However, RAKT results in fewer wound complications, decreased estimated blood loss and pain. Given these benefits, RAKT is a promising approach for obese patient across BMI subtypes and several studies showed decreased wound complications in this population compared with the open approach. Moreover, new 3D-print techniques are promising resources for robotic simulation, which may decrease the learning curve of robotic surgery.

SUMMARY

Overall, RAKT is a feasible approach especially in obese patients. However, more data with long-term follow-up are needed to fully elucidate the advantages over OKT before universal implementation of this approach is possible.

Learning Curve in Robotic Primary Ventral Hernia Repair Using Intraperitoneal Onlay Mesh: A Cumulative Sum Analysis

BACKGROUND

Cumulative sum (CUSUM) learning curves (LCs) are useful to analyze individual performance and to evaluate the acquisition of new skills and the evolution of those skills as experience is accumulated. The purpose of this study is to present a CUSUM LC based on the operative times of robotic intraperitoneal onlay mesh (rIPOM) ventral hernia repair (VHR) and identify differences observed throughout its phases.

MATERIALS AND METHODS

Patients who underwent rIPOM repair for elective, midline, and primary hernias were included. All procedures were performed exclusively by one surgeon within a 5-year period. CUSUM and risk-adjusted CUSUM were used to visualize the LC of rIPOM-VHR, based on operative times and complications. Once groups were obtained, univariate comparisons were performed.

RESULTS

Of the 90 rIPOM repairs, 25, 40, and 25 patients were allocated using a CUSUM analysis to the early, middle, and late phases, respectively. In terms of skin-to-skin times, the middle phase has a mean duration of 23 minutes shorter than the early phase (P<0.001), and the late phase has a mean duration 34 minutes shorter than the early phase (P<0.001). A steep decrease in off-console time was observed, with a 10-minute difference from early to middle phases. A consistent and gradual decrease in operative times was observed after completion of 36 cases, and a risk-adjusted CUSUM revealed improving outcomes after 55 cases.

CONCLUSIONS

This study demonstrates and elucidates interval improvement in operative efficiency in rIPOM-VHR. Consistently decreasing operative times and simultaneous accumulated complication rates were observed after the completion of 55 cases.

Robotic surgery for colorectal cancer

Minimally invasive surgery has demonstrated many benefits in general surgery, particularly in colon and rectal procedures. On the other hand, it has some limitations that must be taken into account, especially technical drawback. Robotic surgery has incorporated many improvements to overcome this disadvantage, such as 3D visualization, articulating instruments assisting complex and precise movements. As a result, robotic colorectal surgery shows less intraoperative blood loss, shorter time to oral tolerance and initial flatus (particularly associated with "Enhanced Recovery After Surgery" protocol), less conversion rate to open surgery, shortened hospital stay, and longer distal margins compared to laparoscopic and open surgery. This approach also shows a shorter learning curve. Some studies suggest that it could decrease perioperatively or 30 days after the intervention's mortality, raise overall survival, reduce wound infection, and improve functional results, while others show no significant difference. However, it lengthens surgical time. Otherwise, the studies included do not show statistically significant changes in the number of resected lymph nodes and anastomotic leaks. Economic costs remain one of the major concerns, although to date there are no large-scale studies that have evaluated this aspect from a global point of view. Robotic surgery represents a qualitative leap in surgical instruments and, although there is no strong evidence in favor of the use of robotic surgery over laparoscopic or open surgery, there is enough evidence to support its use in colorectal surgery, with potential advantages for patients.

Assessment of validity evidence for the RobotiX robot assisted surgery simulator on advanced suturing tasks

Background

Robot assisted surgery has expanded considerably in the past years. Compared to conventional open or laparoscopic surgery, virtual reality (VR) training is an essential component in learning robot assisted surgery. However, for tasks to be implemented in a curriculum, the levels of validity should be studied for proficiency-based training. Therefore, this study was aimed to assess the validity evidence of advanced suturing tasks on a robot assisted VR simulator.

Method

Participants were voluntary recruited and divided in the robotic experienced, laparoscopic experienced or novice group, based on self-reported surgical experience. Subsequently, a questionnaire on a five-point Likert scale was completed to assess the content validity. Three component tasks of complex suturing were performed on the RobotiX simulator (Task1: tilted plane needle transfer, Task: 2 intracorporal suturing, Task 3: anastomosis needle transfer). Accordingly, the outcome of the parameters was used to assess construct validity between robotic experienced and novice participants. Composite scores (0–100) were calculated from the construct parameters and corresponding pass/fail scores with false positive (FP) and false negative (FN) percentages.

Results

Fifteen robotic experienced, 26 laparoscopic experienced and 29 novices were recruited. Overall content validity outcomes were scored positively on the realism (mean 3.7), didactic value (mean 4.0) and usability (mean 4.2). Robotic experienced participants significantly outperformed novices and laparoscopic experienced participants on multiple parameters on all three tasks of complex suturing. Parameters showing construct validity mainly consisted of movement parameters, needle precision and task completion time. Calculated composite pass/fail scores between robotic experienced and novice participants resulted for Task 1 in 73/100 (FP 21%, FN 5%), Task 2 in 85/100 (FP 28%, FN 4%) and Task 3 in 64/100 (FP 49%, FN 22%).

Conclusion

This study assessed the validity evidence on multiple levels of the three studied tasks. The participants score the RobotiX good on the content validity level. The composite pass/fail scores of Tasks 1 and 2 allow for proficiency-based training and could be implemented in a robot assisted surgery training curriculum.

Structured robot-assisted surgery training curriculum for residents in Urology and impact on future surgical activity

To gain insight into the availability of training for robot assisted surgery (RAS) and the possibility to perform RAS during Dutch residency curriculum and to analyze the effects on surgical skills by the introduction of an advanced course in RAS for residents. A combination of a validated snap shot survey and a prospective cohort study. Structured advanced RAS training including virtual reality (VR) simulation, dry and wet lab facility at ORSI academy (Belgium). A snap-shot survey has been sent to all the residents and specialists in Urology graduated during the years 2017-2020 in Netherlands. Among residents, only last year residents (5th and 6th year) have been considered for the RAS training. Although most of the residents (88.2%) and young urologists (95%) were asked to follow a basic training or meet basic requirements before starting RAS, the requirements set by the educators were different from center to center. Some of them were required to attend only an online course on RAS, whereas others were asked to achieve threshold scores at VR simulator and participate in a standardized course at a training institute. The attendance to a structured advanced course in RAS showed a significant increase in surgical skills. Our study shows residents in urology are allowed to perform RAS during their residency though the criteria for starting RAS differ significantly amongst the teaching hospitals. To guarantee a basic level of skills and knowledge a structured, (multi-step) training and certification program for RAS should be implemented.

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.

A Comparative Human-Centric Analysis of Virtual Reality and Dry Lab Training Tasks on the da Vinci Surgical Platform

There is a growing, widespread trend of adopting robot-assisted minimally invasive surgery (RMIS) in clinical care. Dry lab robot training and virtual reality simulation are commonly used to train surgical residents; however, it is unclear whether both types of training are equivalent or can be interchangeable and still achieve the same results in terms of training outcomes. In this paper, we take the first step in comparing the effects of physical and simulated surgical training tasks on human operator kinematics and physiological response to provide a richer understanding of exactly how the user interacts with the actual or simulated surgical robot. Four subjects, with expertise levels ranging from novice to expert surgeon, were recruited to perform three surgical tasks — Continuous Suture, Pick and Place, Tubes, with three repetitions — on two training platforms: (1) the da Vinci Si Skills Simulator and (2) da Vinci S robot, in a randomized order. We collected physiological response and kinematic movement data through body-worn sensors for a total of 72 individual experimental trials. A range of expertise was chosen for this experiment to wash out inherent differences based on expertise and only focus on inherent differences between the virtual reality and dry lab platforms. Our results show significant differences ([Formula: see text]-[Formula: see text]) between tasks done on the simulator and surgical robot. Specifically, robotic tasks resulted in significantly higher muscle activation and path length, and significantly lower economy of volume. The individual tasks also had significant differences in various kinematic and physiological metrics, leading to significant interaction effects between the task type and training platform. These results indicate that the presence of the robotic system may make surgical training tasks more difficult for the human operator. Thus, the potentially detrimental effects of virtual reality training alone are an important topic for future investigation.

Learning curve in robotic transabdominal preperitoneal (rTAPP) ventral hernia repair: a cumulative sum (CUSUM) analysis

Purpose

rTAPP-VHR is a novel technique which may be added to a surgeon’s armamentarium. We aim to evaluate the robotic transabdominal preperitoneal ventral hernia repair (rTAPP-VHR) learning curve based on operative times while accounting for peritoneal flap integrity.

Methods

We performed a retrospective analysis of a database collected over a 7-year period. Patients with primary ventral hernias were included and a cumulative sum analysis(CUSUM) was used to create learning curves for three subsets of operative times. A risk-adjusted CUSUM (RA-CUSUM) accounted for repair quality based on peritoneal flap completeness. The flap was considered as incomplete when peritoneal gaps were unable to be closed.

Results

105 patients undergoing rTAPP-VHR were included. Learning curves were created for skin-to-skin, console, and off-console times. Patients were divided into three phases. In terms of skin-to-skin times, both phase 2&3 had a mean 11 min shorter than that of phase 1 (p = 0.0498, p = 0.0245, respectively), with a steady decrease after forty-six cases. An incomplete peritoneal flap was noted in 25/36 patients in phase 1, as compared to 5/24 and 5/45 patients in phase 2&3, respectively. When risk-adjusted for peritoneal flap completeness, gradually decreasing skin-to-skin times were observed after sixty-one cases. In terms of off-console times, the mean across three phases was 14 min, with marked improvement after forty-three cases.

Conclusions

Forty-six cases were needed to achieve steadily decreasing operative times. We can assume that ensuring good-quality repairs, through maintenance of peritoneal flap integrity, was gradually improved after sixty-one cases. Moreover, familiarization with port placements and robotic docking was accomplished after forty-three cases.

How to report educational videos in robotic surgery: an international multidisciplinary consensus statement

The swift endorsement of the robotic surgical platform indicates that it might prevail as the preferred technique for many complex abdominal and pelvic operations. Nonetheless, use of the surgical robotic system introduces further layers of complexity into the operating theatre necessitating new training models. Instructive videos with relevant exposition could be optimal for early training in robotic surgery and the aim of this study was to develop consensus guidelines on how to report a robotic surgery video for educational purposes to achieve high quality educational video outputs that could enhance surgical training. A steering group prepared a Delphi survey of 46 statements, which was distributed and voted on utilising an electronic survey tool. The selection of committee members was designed to include representative surgical trainers worldwide across different specialties, including lower and upper gastrointestinal surgery, general surgery, gynaecology and urology. 36 consensus statements were approved and classified in seven categories: author’s information and video introduction, case presentation, demonstration of the surgical procedure, outcomes of the procedure, associated educational content, review of surgical videos quality and use of surgical videos in educational curricula. Consensus guidelines on how to report robotic surgery videos for educational purposes have been elaborated utilising Delphi methodology. We recommend that adherence to the guidelines presented could support advancing the educational quality of video outputs when designed for training.

The development of a robotic gynaecological surgery training curriculum and results of a delphi study

BACKGROUND

Technology for minimal access surgery is rapidly progressing in all surgical specialities including Gynaecology. As robotic surgery becomes established in increasing numbers of hospitals, there is no set curriculum for training in robotic gynaecological surgery or the assistant role in use in the UK. The purpose of this study was to determine a list of competencies that could be used as the basis of a core robotic gynaecological surgery curriculum, to explore its acceptability and the level of interest in undertaking training in robotics among obstetrics & gynaecology (O&G) trainees.

METHODS

A four-round Delphi study was conducted using members and associates of British & Irish Association of Robotic Gynaecological Surgeons (BIARGS). In Round 1 respondents were asked to propose standards that could be used in the curriculum. In the following three rounds, the respondents were asked to score each of the standards according to their opinion as to the importance of the standard. Items that scored a mean of 80% or above were included in the final proposed curriculum. Following this, a national survey was conducted to explore the interest among O&G trainees in undertaking a formal robotic training for the first assistant and console surgeon roles.

RESULTS

The items proposed were divided into three separate sections: competencies for a medical first assistant; competencies for a console surgeon; continued professional development for trained console surgeons. From the national survey; 109 responses were received of which 60% were interested in undertaking a formal training for the first assistant role, and 68% are expressing interest in training for the console surgeon role.

CONCLUSION

Undertaking a Delphi exercise to determine a core gynaecological robotic training curriculum has enabled consensus to be achieved from the opinions of BIARGS members/associates. There is interest among O&G trainees at all levels of training to gain experience and develop their skills in robotic surgery by undertaking a formal training in robotic surgery at both the first assistant and console surgeon level.

Newly trained operating room nurses' experiences of nursing care in the operating room

There is limited research on nurses' experiences of nursing care in the operating room. The operating room nurses' responsibility is to ensure good nursing care before, during and after surgery. In an increasingly technological health care environment, there is always a risk of turning the focus away from nursing care towards technology and medicine. Integration of past experiences into the role as an operating room nurse becomes a challenge for those who recently worked as general nurses. The present study aimed to explore newly trained operating room nurses' experiences of nursing care in an operating room. Semi-structured interviews were performed with ten operating room nurses with a maximum three years' work experience from an operating room. The interviews were subjected to qualitative content analysis. The findings revealed three themes describing operating room nurses' searching for their new role. They experienced a gap between theory and practice, felt alone and insignificant and had to find their own place. The operating room nurses' experienced threats to safe nursing when they lacked time for the patients as well as for their own recovery, and they lacked feedback in order to improve care. They ensured security for patients by establishing one-to-one contact, protecting patients' well-being and working in teams for the patients' best interest, participants also focused on the task at hand instead of the patient as a person. New ways of organising work in operating units, and well-functioning teams can be a key to a successful integration of experiences from ward nurse to an operating room nurse, and provide support so that they feel more visible, at ease and safe in their new profession.

The application of virtual reality training for anastomosis during robot-assisted radical prostatectomy

Objective

To investigate the application of virtual reality training in vesicourethral anastomosis during robot-assisted radical prostatectomy (RARP).

Methods

Three certified robotic urologists who underwent virtual reality training were enrolled in the study group. The other three without training were enrolled in the control group. Parameters were recorded before and after the training. Then a total of 18 patients undergoing RARP were enrolled and randomized assigned to receive anastomosis procedures with certified urologists who either obtained or did not obtain training. The quality of the anastomosis was evaluated.

Results

For the virtual training evaluation, the overall score was significantly improved from 65.0±10.8 to 92.7±3.5 (p=0.014); the time of anastomosis was shortened; the economy of motion improved; instrument collisions decreased after training (p<0.05). Besides, the effectiveness of the virtual training was evaluated in the 18 real anastomosis procedures which were completed either by three urologists with training or three urologists without training. Most intriguingly, the average time of anastomosis was shortened from 40.0±12.4 min to 25.1±7.1 min (p=0.015). The parameters including time of operation, creatinine level of drainage, postoperative hospital stay and duration of catheter drainage were comparable before and after training. Two leakages, which were observed in procedures by doctors without training, needed salvage sutures by a senior doctor.

Conclusions

Virtual reality training enabled surgeons to become quickly familiar with robotic system manipulation, improved their skills for vesicourethral anastomosis and shortened the learning curve, thus helping them operate with high efficacy and quality.

Attitudes of robotic surgery educators and learners: challenges, advantages, tips and tricks of teaching and learning robotic surgery

As the application of robotic surgical technology grows, so does the need to instruct surgical residents in robotic techniques. To better understand the challenges and benefits unique to robotic surgery education, this study explored the attitudes of teachers and learners. A 43-item questionnaire was developed with five domains: challenges and benefits of robotic education, training methodologies, trainees' readiness for learning, and education tips. This was delivered to surgeons and surgical fellows at a high-volume surgical department. 31 surgeons and 25 fellows from 7 specialties responded (response rate 70% and 43%). The teaching and learning of robotic surgery were perceived as superior to traditional minimally invasive surgery by both surgeons (in 7/9 factors studied) and fellows (7/9), but was seen as mostly disadvantageous compared to open surgery by both surgeons (in 6/9 factors studied) and fellows (8/9). Surgeons frequently stated the greatest challenge to teaching robotics was the need to relinquish total control to the trainee. Robotic surgery education is generally well received and offers several advantages. However, teaching robotic surgery presents unique challenges, especially when compared to open surgery. Understanding the benefits of, and barriers to, robotic surgery education may help develop more effective training paradigms that are responsive to educational needs while maintaining patient safety.

The safety of urologic robotic surgery depends on the skills of the surgeon

PURPOSE

To assess the available literature evidence that discusses the effect of surgical experience on patient outcomes in robotic setting. This information is used to help understand how we can develop a learning process that allows surgeons to maximally accommodate patient safety.

METHODS

A literature search of the MEDLINE/PubMed and Scopus database was performed. Original and review articles published in the English language were included after an interactive peer-review process of the panel.

RESULTS

Robotic surgical procedures require high level of experience to guarantee patient safety. This means that, for some procedures, the learning process might be longer than originally expected. In this context, structured training programs that assist surgeons to improve outcomes during their learning processes were extensively discussed. We identified few structured robotic curricula and demonstrated that for some procedures, curriculum trained surgeons can achieve outcomes rates during their initial learning phases that are at least comparable to those of experienced surgeons from high-volume centres. Finally, the importance of non-technical skills on patient safety and of their inclusion in robotic training programs was also assessed.

CONCLUSION

To guarantee safe robotic surgery and to optimize patient outcomes during the learning process, standardized and validated training programs are instrumental. To date, only few structured validated curricula exist for standardized training and further efforts are needed in this direction.

Comparison of effective teaching methods to achieve skill acquisition using a robotic virtual reality simulator: Expert proctoring versus an educational video versus independent training

BACKGROUND

To compare the superiority of teaching methods for acquiring a proficient level of surgical skill in a robotic surgery-naïve individual using a robotic virtual reality simulator.

METHODS

This study employed a prospective, randomized study design to assess student's learning curve. We divided 45 subjects into 3 groups: those with expert proctoring (group I), those who watched only an educational video (group II), and those with independent training (group III; n = 15 per group). The task used in this study was the Tube 2 and it imitates a vesicourethral anastomosis in robotic prostatectomy. The effects were analyzed by the time to end the task after overcoming the learning curve which is determined by several performance parameters.

RESULTS

The number of task repetitions required to reach the learning curve plateau was 45, 42, and 37 repetitions in groups I, II, and III, which means that there was continuous improvement in performing the task after 40 repetitions only in groups I and II. The mean time for completing the task during the stabilization period was significantly different between group I and group III and group II and group III, which means that the independent training method was inferior to the other methods (group I vs. group II vs. group III: 187.38 vs. 187.07 vs. 253.47 seconds, P < .001).

CONCLUSIONS

This study's findings showed that an educational video can be as beneficial as expert proctoring, which implies that the development of a standardized educational video would be worthwhile.

The value of a 1-day multidisciplinary robot surgery training for novice robot surgeons

INTRODUCTION

To fulfil the need for a basic level of competence in robotic surgery (Brinkman et al., Surg Endosc Other Interv Tech 31(1):281-287, 2017; Dutch Health inspectorate (Inspectie voor de gezondheidszorg), Insufficient carefulness at the introduction of surgical robots (in Dutch: Onvoldoende zorgvuldigheid bij introductie van operatierobots), Igz, Utrecht, 2010), the NIVEL (Netherlands Institute for Healthcare Research) developed the 'Basic proficiency requirements for the safe use of robotic surgery' (BPR). Based on the BPR a 1-day robotic surgery training was organised to answer the following research questions: (1) Are novice robot surgeons able to accurately self-assess their knowledge and dexterity skills? (2) Is it possible to include the teaching of all BPRs in a 1-day training?

MATERIALS AND METHODS

Based on the BPR, a robot surgery course was developed for residents and specialists (surgery, gynaecology and urology). In preparation, the participants completed an online e-module. The 1-day training consisted of a practical part on robot set-up, a theoretical section, and hands-on exercises on virtual reality robot simulators. Multiple online questionnaire was filled out by the participants at the end of the training to evaluate the perceived educational value of the course and to self-assess the degree to which BPRs were reached.

RESULTS

20 participants completed the training during the conference of the Dutch Association for Endoscopic Surgery (NVEC) in 2017. Participants indicated nearly all competency requirements were mastered at the end of the training. The competency requirements not mastered were, however, critical requirements for the safe use of the surgical robot. Skill simulation results show a majority of participants are unable to reach a proficient simulation score in basic skill simulation exercises.

CONCLUSION

Results show novice robot surgeons are too positive in the self-assessment of their own dexterity skills after a 1-day training. Self-assessment revealed uncertainty of the obtained knowledge level on requirements for the safe use of the surgical robot. Basic courses on robotic training should inform trainees about their results to enhance learning and inform them of their competence levels.

Validity evidence for procedural competency in virtual reality robotic simulation, establishing a credible pass/fail standard for the vaginal cuff closure procedure

BACKGROUND

The use of robotic surgery for minimally invasive procedures has increased considerably over the last decade. Robotic surgery has potential advantages compared to laparoscopic surgery but also requires new skills. Using virtual reality (VR) simulation to facilitate the acquisition of these new skills could potentially benefit training of robotic surgical skills and also be a crucial step in developing a robotic surgical training curriculum. The study's objective was to establish validity evidence for a simulation-based test for procedural competency for the vaginal cuff closure procedure that can be used in a future simulation-based, mastery learning training curriculum.

METHODS

Eleven novice gynaecological surgeons without prior robotic experience and 11 experienced gynaecological robotic surgeons (> 30 robotic procedures) were recruited. After familiarization with the VR simulator, participants completed the module 'Guided Vaginal Cuff Closure' six times. Validity evidence was investigated for 18 preselected simulator metrics. The internal consistency was assessed using Cronbach's alpha and a composite score was calculated based on metrics with significant discriminative ability between the two groups. Finally, a pass/fail standard was established using the contrasting groups' method.

RESULTS

The experienced surgeons significantly outperformed the novice surgeons on 6 of the 18 metrics. The internal consistency was 0.58 (Cronbach's alpha). The experienced surgeons' mean composite score for all six repetitions were significantly better than the novice surgeons' (76.1 vs. 63.0, respectively, p < 0.001). A pass/fail standard of 75/100 was established. Four novice surgeons passed this standard (false positives) and three experienced surgeons failed (false negatives).

CONCLUSION

Our study has gathered validity evidence for a simulation-based test for procedural robotic surgical competency in the vaginal cuff closure procedure and established a credible pass/fail standard for future proficiency-based training.

Impact of Sentinel Node Approach in Gynecologic Cancer on Training Needs

STUDY OBJECTIVE

We sought to estimate the impact of sentinel nodes in gynecologic oncology on fellowship training and discuss potential solutions.

DESIGN

Retrospective multi-institution cohort (Canadian Task Force classification II-2).

SETTING

Three tertiary cancer referral cancer centers.

PATIENTS

Patients with endometrial and vulvar cancer undergoing lymph node evaluation.

INTERVENTIONS

Patient history and fellow case volumes were evaluated retrospectively for type of lymph node assessment.

MEASUREMENTS AND MAIN RESULTS

Minimally invasive endometrial cancer and vulvar cancer fellow case volumes in 3 large institutions were reviewed and average annual volumes calculated for each clinical gynecologic oncology fellow. For vulvar cancer, probabilities of sentinel lymph node mapping and laterality of lesions were estimated from the literature. For endometrial cancer, estimates of lymphadenectomy rates were determined using probabilities calculated from our historic database and from review of the literature. Modeling the approaches to lymphadenectomy in endometrial cancer (full, selective, and sentinel), 100% versus 68% versus 24%, respectively, of patients would require complete pelvic lymphadenectomy and 100% versus 34% versus 12% would require para-aortic lymphadenectomy. In vulvar cancer, rates of inguinal femoral lymphadenectomy are expected to drop from 81% of unilateral groins to only 12% of groins.

CONCLUSIONS

Sentinel lymph node biopsy for endometrial and vulvar cancer will play an increasing role in practice, and coincident with this will be a dramatic decrease in pelvic, para-aortic, and inguinal femoral lymphadenectomies. The declining numbers will require new strategies to maintain competency in our specialty. New approaches to surgical training and continued medical education will be necessary to ensure adequate training for fellows and young faculty across gynecologic surgery.

Initial and Long-term Retention of Robotic Technical Skills in an Otolaryngology Residency Program

OBJECTIVES/HYPOTHESIS

To objectively assess the initial and long-term retention of robotic surgical skills of otolaryngology residents.

STUDY DESIGN

This study was performed in an academic otolaryngology residency training program. Between October 2015 and November 2016, residents were invited to complete a prospective, multiphase robotic surgical skills training course: 1) online da Vinci Surgical System Assessment and didactic, 2) faculty-supervised robotic simulator training, 3) robotic docking and draping training, 4) robotic dry-lab exercises. To optimize surgical skill retention, the training laboratory was repeated 2 weeks after the initial training session.

METHODS

Twenty otolaryngology residents were included. Primary outcome was measured as robotic skill assessment scores on three tasks: camera targeting, peg board, and needle targeting. Skill assessments were completed prior to training, between the two training sessions, and at 1 month and 6 months after training. Residents were also asked to complete a self-assessment questionnaire.

RESULTS

Camera targeting scores were improved at midtraining (P < .001) and 1-month posttraining (P = .010). Peg board scores were improved at 1 month training (P = .043). Needle targeting scores were improved at midtraining (P = .002), 1 month (P = .002), and 6 months posttraining (P < .001). Resident self-assessment scores demonstrating comfort with using the robotic console (P < .01) and docking/draping (P < .01) improved significantly following the training.

CONCLUSIONS

Following a multiphase robotic training program, otolaryngology residents demonstrated significant, objective skill acquisition and retention at 1 month and 6 months follow-up. Although the proposed training strategy may be considered an important step in otolaryngology residency training, additional innovations are being designed toward a formal robotic training curriculum.
