Robotic surgery training curricula: prevalence, perceptions, and educational experiences in general surgery residency programs

Cross Sectional Survey of Ob/Gyn Residents' Graduated Experience With Robotic Surgery

STUDY OBJECTIVE

Obstetrics and gynecology (Ob/Gyn) resident experience with robotic gynecologic surgery has been evaluated at time of graduation, but no specific surgical procedures were identified to differentiate the experiences of residents at each level. This study proposes to determine which factors are correlated with more hands-on robotic surgery experience and resident satisfaction.

DESIGN

An Investigational Review Board-approved, 15-question survey was distributed electronically. Ninety-eight responses were received for a rate of 44%. Linear regression and Analysis of Variance statistical analysis were performed.

SETTING

Current residents at 8 Ob/gyn residency programs in the US were surveyed.

PATIENTS

N/A.

INTERVENTIONS

Survey administration.

MEASUREMENT AND MAIN RESULTS

The majority of respondents were satisfied (48%) or had neutral feelings (20%) with regard to their robotic surgery experience. All respondents reported experience with uterine manipulation or bedside assistance by postgraduate year (PGY) 2. Earliest experience performing hysterectomy was most common in PGY2 or PGY3. Seventy-six percent of PGY3 or PGY4 residents report operating on the console for some or all major robotic surgeries, with 69% having participated in greater than 20 robotic surgery cases during residency. Only exposure to Minimally Invasive Gynecologic Surgery faculty is significantly associated with high robotic surgery experience (p = .022). Overall satisfaction with robotic surgery experience increased significantly with higher level of participation (p <.0001), particularly operating at the console during some or most of the surgery; longitudinal experiences with hysterectomy, myomectomy, and salpingectomy/oophorectomy (p <.05); but not with sole bedside assisting or vaginal cuff closure. Factors limiting robotic console experience included case time constraints, lack of first assists, case complexity, and attending comfort.

CONCLUSIONS

Ob/Gyn resident satisfaction with training is significantly related to level and duration of robotic surgery participation. Minimally Invasive Gynecologic Surgery faculty contribute to more resident experience, and limiting factors include time constraints, case complexity, and lack of first assists. These results can provide a framework for structuring resident training in robotic surgery.

Making surgical education intuitive: A surgical robotics primer for pre-clinical medical students

BACKGROUND

As robotic surgeries increase nationwide, residency programs are implementing commensurate curriculum. Medical student exposure and comfort with these surgeries, however, is lagging. This program sought to improve student interest and confidence through additional robotic exposure.

METHODS

A two-part educational program was implemented at an academic institution. Part-one included a surgeon-led lecture and part-two a hands-on robotics primer where students were exposed to 3-D anatomy and instrumentation via robotic console. Data was collected via RedCap and analyzed for significance (p ​< ​0.05).

RESULTS

Thirty-two students participated in part one, ten of which were selected for part two. The majority (82 ​%) reported being interested or very interested in pursuing additional robotic experiences and 40 ​% reported improved confidence in actively assisting in a robotics case (p ​< ​0.005).

CONCLUSION

Conducting robotic exposure events improves medical students' confidence and interest in seeking future robotic surgery experiences. As robotic surgery expands, medical students have shown to benefit from earlier exposure.

Educational needs of the EAES young surgeons

INTRODUCTION

Surgical residency programs are facing ongoing challenges since the pandemic. The Young Member (YM) Task Force of the European Association for Endoscopic Surgery (EAES) has been created to support surgical residents and surgeons under 40, promoting activities that could be useful for young surgeons and to improve networking between members of different countries. This project aimed to explore educational needs among European surgical residents to inform the EAES curriculum for young surgeons.

METHODS

Within the EAES surgical society, the YM developed a survey to capture residents' views on their professional needs. Different aspects were considered, from demographic information to the major topics of interest on a professional side. Semi-automatic answers and personal suggestions have been gathered and considered for the analysis.

RESULTS

Data were captured from 386 respondents across 57 different countries, major responders were represented by the group of 31-35 years old (40%). Considering professional growth, young surgeons rely on scientific research (56%), but they struggle finding adequate support of facilities. In the education and training section, fellowships and hands-on-courses (27%) were the most proficient activities. Mentorships and webinars were important to develop leadership, as well as social events to build up a professional network.

CONCLUSION

This project has identified young surgeons' educational and professional needs that can inform the EAES future projects and activities.

A Systematic Review of Current Practices, Challenges, and Future Directions for the Use of Robotic Surgery in Otolaryngology in Greece

Robotic surgery is increasingly used in otolaryngology (ENT), particularly for complex head and neck procedures. It offers various advantages, including limited postoperative pain, excellent aesthetic results, better visualization in the surgical field, enhanced dexterity due to movement adjustment by the robotic system, and minimal complications and hospital stay. However, robotic systems' higher cost and limited availability are a burden for clinical applications. This systematic review is a detailed assessment that looks at the existing situation, problems, and prospects for robotic ENT surgery in Greece. It is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. The included studies were chosen based on specific criteria after a thorough inspection of electronic databases of clinical trials and medical journals (PubMed, Scopus, Web of Science). Despite steady adoption, Greece needs to catch up with other European countries in deploying robotic surgery technology. Various possible reasons may cause the small number of ENT robotic-assisted surgeries, including the high cost and the availability of robotic systems, mainly in large private or public hospitals in the main cities of Greece (Athens and Thessaloniki). Training on robotic systems is also very limited for surgery residents and young surgeons, while the learning curve of robotic-assisted surgeries in ENT is big. Peer-reviewed literature was analyzed to compare it with other European nations and investigate the economic, training, and geographic aspects that may be a burden for the rise of robotic surgery in Greece. Through the review scope, this study also provided recommendations concerning the implementation of robotic surgery in daily practice among surgeons in Greece and the difficulties that may arise regarding robotic surgery training in resource-limited countries.

Current status of resident simulation training curricula: pearls and pitfalls

BACKGROUND

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.

MATERIALS AND METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Laparoscopic vs robotic inguinal hernia repair: a comparison of learning curves and skill transference in general surgery residents

BACKGROUND

There is no consensus on whether laparoscopic experience should be a prerequisite for robotic training. Further, there is limited information on skill transference between laparoscopic and robotic techniques. This study focused on the general surgery residents' learning curve and skill transference within the two minimally invasive platforms.

METHODS

General surgery residents were observed during the performance of laparoscopic and robotic inguinal hernia repairs. The recorded data included objective measures (operative time, resident participation indicated by percent active time on console or laparoscopy relative to total case time, number of handoffs between the resident and attending), and subjective evaluations (preceptor and trainee assessments of operative performance) while controlling for case complexity, patient comorbidities, and residents' prior operative experience. Wilcoxon two-sample tests and Pearson Correlation coefficients were used for analysis.

RESULTS

Twenty laparoscopic and forty-four robotic cases were observed. Mean operative times were 90 min for robotic and 95 min for laparoscopic cases (P = 0.4590). Residents' active participation time was 66% on the robotic platform and 37% for laparoscopic (P =  < 0.0001). On average, hand-offs occurred 9.7 times during robotic cases and 6.3 times during laparoscopic cases (P = 0.0131). The mean number of cases per resident was 5.86 robotic and 1.67 laparoscopic (P = 0.0312). For robotic cases, there was a strong correlation between percent active resident participation and their prior robotic experience (r = 0.78) while there was a weaker correlation with prior laparoscopic experience (r = 0.47). On the other hand, prior robotic experience had minimal correlation with the percent active resident participation in laparoscopic cases (r = 0.12) and a weak correlation with prior laparoscopic experience (r = 0.37).

CONCLUSION

The robotic platform may be a more effective teaching tool with a higher degree of entrustability indicated by the higher mean resident participation. We observed a greater degree of skill transference from laparoscopy to the robot, indicated by a higher degree of correlation between the resident's prior laparoscopic experience and the percent console time in robotic cases. There was minimal correlation between residents' prior robotic experience and their participation in laparoscopic cases. Our findings suggest that the learning curve for the robot may be shorter as prior robotic experience had a much stronger association with future robotic performance compared to the association observed in laparoscopy.

How to integrate robotic training in surgical residency? An example of a 2-week robotic rotation

General surgery residents should be proficiently trained in robotic surgery. However, there is currently no standardized robotic training curriculum. We aimed to evaluate two approaches to a robotic curriculum and how implementing a virtual reality (VR) simulation curriculum improves trainee robotic performance. From 2019 to 2022, two models of a robotic training curriculum were examined: an in-unit rotation (IUR) and a 2-week curriculum (2WR). The VR curriculum was completed using the da Vinci® Skill Simulator. The curriculum used a pre/post-test design. Residents completed a pre-test that consisted of 4 VR exercises (graded 0-100%) and 3 inanimate box trainer exercises (graded using modified Objective Structured Assessment of Technical Skills). Then, residents completed a VR curriculum of 23 modules. Following the curriculum, residents were given a post-test with the same pre-test exercises. Time necessary to complete the curriculum and compliance were recorded. Of the 11 residents who participated in the IUR, 4 completed the VR curriculum. Comparatively, 100% (n = 23) of residents in the 2WR completed the curriculum. Average time to complete the VR curriculum was 3.8 h. After completion of the 2WR curriculum, resident performance improved from pre-test to post-test: VR test scores increased (160% vs 223%, p < 0.001), OSATS scores increased (15.0 vs 21.0, p < 0.001), and time to complete inanimate exercises decreased (1083 vs 756 s, p = 0.001). Residents who mastered all modules had higher post-test VR scores (241% vs 214%, p = 0.024). General surgery residents demonstrated improved compliance with the 2WR. The VR curriculum improved resident robotic performance in both virtual and inanimate domains.

Is implementation of robotic-assisted procedures in acute care general surgery cost-effective?

Over the past 2 decades, the use and importance of robotic surgery in minimally invasive surgery has increased. Across various surgical specialties, robotic technology has gained popularity through its use of 3D visualization, optimal ergonomic positioning, and precise instrument manipulation. This growing interest has also been seen in acute care surgery, where laparoscopic procedures are used more frequently. Despite the growing popularity of robotic surgery in the acute care surgical realm, there is very little research on the utility of robotics regarding its effects on health outcomes and cost-effectiveness. The current literature indicates some value in utilizing robotic technology in specific urgent procedures, such as cholecystectomies and incarcerated hernia repairs; however, the high cost of robotic surgery was found to be a potential barrier to its widespread use in acute care surgery. This narrative literature review aims to determine the cost-effectiveness of robotic-assisted surgery (RAS) in surgical procedures that are often done in urgent settings: cholecystectomies, inguinal hernia repair, ventral hernia repair, and appendectomies.

The distribution of robotic surgery in general and visceral surgery departments in Switzerland - a nationwide inquiry

Objectives

Since its introduction as a clinical technique, robotic surgery has been extended to different fields of surgery. However, the indications as well as the number of robotic procedures varied in different institutions. The aim of this investigation was to evaluate the current use of robotic surgery in general and digestive surgery in Switzerland.

Methods

All Swiss surgical departments that are recognized training institutes for postgraduate training in surgery by the Swiss Institute of Medical Education (SIWF) were queried with a detailed questionnaire regarding the use of robotic surgery techniques and were analyzed regarding hospital size and type of hospital.

Results

Ninety-three departments were queried, and 67 % (n=63) answered the survey. Fifty-eight were public, and five were private institutions. Seventeen (26 %) of the queried departments used robotic surgery in digestive surgery. Four out of 17 (23 %) of the departments that performed robotic surgery were private hospitals, while 13 (77 %) were public institutions. In the majority of departments, robotic surgery of the rectum (n=12; 70.6 %) and colon (n=11; 64.7 %) was performed, followed by hernia procedures (n=8; 47.1 %) and fundoplication (n=7; 41.2 %). Less frequently, pancreatic resections (n=5; 29.4 %), cholecystectomy (n=4; 23.5 %), adrenalectomy (n=4; 23.5 %), gastric bypass (n=3; 17.7 %), gastric sleeve (n=3; 17.7 %), hepatic procedures (n=2; 11.7 %), or small bowel resections (n=1; 5.9 %) were performed as robotic procedures. More than 25 procedures per year per department were performed for hernia surgery (n=5 departments), gastric bypass (n=2 departments), cholecystectomy, fundoplication, and colon surgery (each n=1 department).

Conclusions

The number and range of robotic procedures performed in Switzerland varied widely. Higher accreditation for general surgery or subspecialization of visceral surgery of the department was positively associated with the use of robotic techniques, reflecting an unequal availability of robotic surgery.

Incentive policy for the comprehensive development of young medical talents: an evolutionary game study

Introduction

Currently in China, there is a lack of well-defined and viable incentive mechanisms at the governmental and hospital levels to support the development of young medical talents, thereby hindering their growth Existing studies primarily investigate the current state and trajectory of incentives, yet they inadequately address the distinctive characteristics of various stakeholders involved in medical talent incentive processes, particularly the lack of research on incentive mechanisms with Chinese attributes.

Methods

This study adopts evolutionary game theory to investigate the dynamics of replication and the strategies for achieving evolutionary stability in the comprehensive development of young medical talents, considering both scenarios with and without supportive policies.

Results

In the absence of any supportive policy measures, the evolutionarily stable strategy (ESS) point is O(0,0), the unstable equilibrium point is C(1,1), and the saddle points are A(0,1), B(1,0). The initial state of the system is at the unstable equilibrium point C(1,1), which means that the young medical talents and medical institutions adopt a combination of strategies (actively seeking comprehensive development and taking incentive measures). Under the scenario with supportive policies, the ESS point is C(1,1), the unstable equilibrium point is O(0,0), and the saddle points are A(0,1), B(1,0). The initial state of the system is at the unstable equilibrium point O(0,0), which means that young medical talents and medical institutions adopt (N,N) strategy combinations (inactively seeking comprehensive development, implementing no incentive measure).

Discussion

(1) Government incentives play a crucial role in motivating young medical talents to seek comprehensive development. (2) The level of government incentive support for young medical talents should exceed the cost increment of individual efforts. Additionally, the policy support provided by the government to medical institutions should surpass the incentive support offered by these institutions to young medical talents. This will enhance the motivation and encouragement efforts of medical institutions in actively promoting comprehensive development among young medical talents. (3) With the backing of certain government incentive policies, medical institutions implementing incentive measures and young medical talents actively seeking comprehensive development will establish a virtuous cycle of mutual promotion.

Is Robotic Console Time a Surrogate for Resident Operative Autonomy?

OBJECTIVE

Robotic-assisted surgery is an increasing part of general surgery training, but resident autonomy on the robotic platform can be hard to quantify. Robotic console time (RCT), the percentage of time the resident controls the console, may be an appropriate measure of resident operative autonomy. This study aims to characterize the correlation between objective resident RCT and subjectively scored operative autonomy.

METHODS

Using a validated resident performance evaluation instrument, we collected resident operative autonomy ratings from residents and attendings performing robotic cholecystectomy (RC) and robotic inguinal hernia repair (IH) at a university-based general surgery program between 9/2020-6/2021. We then extracted RCT data from the Intuitive surgical system. Descriptive statistics, t-tests and ANOVA were performed.

RESULTS

A total of 31 robotic operations (13 RC, 18 IH) performed by 4 attending surgeons and 8 residents (4 junior, 4 senior) were matched and included. 83.9% of cases were scored by both attending and resident. The average RCT per case was 35.6%(95% CI 13.0%,58.3%) for junior residents (PGY 2-3) and 59.7%(CI 51.1%,68.3%) for senior residents (PGY 4-5). The mean autonomy evaluated by residents was 3.29(CI 2.85,3.73) out of a maximum score of 5, while the mean autonomy evaluated by attendings was 4.12(CI 3.68,4.55). RCT significantly correlated with subjective evaluations of resident autonomy (r=0.61, p=0.0003). RCT also moderately correlated with resident training level (r=0.5306, p<0.0001). Neither attending robotic experience nor operation type significantly correlated with RCT or autonomy evaluation scores.

CONCLUSIONS

Our study suggests that resident console time is a valid surrogate for resident operative autonomy in robotic cholecystectomy and inguinal hernia repair. RCT may be a valuable measure in objective assessment of residents' operative autonomy and training efficiency. Future investigation into how RCT correlates with subjective and objective autonomy metrics such as verbal guidance or distinguishing critical operative steps is needed to validate the study findings further.

What influences general surgery residents' prospective entrustment and operative time in robotic inguinal hernia repairs

INTRODUCTION

Teaching residents robotic-assisted inguinal hernia repair (RIHR) is an increasingly common extension of contemporary surgical training. This study sought to investigate what variables would influence operative time (OT) and resident prospective entrustment in RIHR cases.

METHODS

We prospectively collected 68 resident RIHR operative performance evaluations with a validated instrument. Outpatient RIHR cases performed by 11 general surgery residents during 2020-2022 were included. The overall OT of matched cases was extracted from hospital billing; matched procedural step-specific OT was obtained from Intuitive Data Recorder (IDR). Statistical analysis was performed using Pearson correlation and one-way ANOVA.

RESULTS

The evaluation instrument reliably assessed residents' RIHR performance (Cronbach's α = 0.93); residents' prospective entrustment strongly correlated with overall guidance provided by attending surgeon (r = 0.86, p < 0.0001) and operative plan and judgment (r = 0.85, p < 0.0001). The overall OT was significantly associated with resident's team management (r = - 0.35, p = 0.011). Procedural step-specific OT was significantly associated with residents' step-specific skill (r = - 0.32, p = 0.014). On average, RIHR cases with the highest level of prospective entrustment (Resident can teach junior) showed the shortest step-specific OT. Entrustment level 3 (Reactive guidance needed) was the turning point of all four RIHR procedural step-specific OT.

CONCLUSIONS

Our findings suggest that in RIHR, attending guidance, resident operative plan and judgment, and resident technical skill contribute to resident prospective entrustment; resident team management, technical skill, and attending guidance influence operative time, which in turn impacts attendings' determination of resident prospective entrustment. Future studies with a larger sample size are needed to further validate the findings.

Utilising an accelerated Delphi process to develop consensus on the requirement and components of a pre-procedural core robotic surgery curriculum

Robot-assisted surgery (RAS) continues to grow globally. Despite this, in the UK and Ireland, it is estimated that over 70% of surgical trainees across all specialities have no access to robot-assisted surgical training (RAST). This study aimed to provide educational stakeholders guidance on a pre-procedural core robotic surgery curriculum (PPCRC) from the perspective of the end user; the surgical trainee. The study was conducted in four Phases: P1: a steering group was formed to review current literature and summarise the evidence, P2: Pan-Specialty Trainee Panel Virtual Classroom Discussion, P3: Accelerated Delphi Process and P4: Formulation of Recommendations. Forty-three surgeons in training representing all surgical specialties and training levels contributed to the three round Delphi process. Additions to the second- and third-round surveys were formulated based on the answers and comments from previous rounds. Consensus opinion was defined as ≥ 80% agreement. There was 100% response from all three rounds. The resulting formulated guidance showed good internal consistency, with a Cronbach alpha of > 0.8. There was 97.7% agreement that a standardised PPCRC would be advantageous to training and that, independent of speciality, there should be a common approach (95.5% agreement). Consensus was reached in multiple areas: 1. Experience and Exposure, 2. Access and context, 3. Curriculum Components, 4 Target Groups and Delivery, 5. Objective Metrics, Benchmarking and Assessment. Using the Delphi methodology, we achieved multispecialty consensus among trainees to develop and reach content validation for the requirements and components of a PPCRC. This guidance will benefit from further validation following implementation.

Robotic pancreatoduodenectomy: trends in technique and training challenges

BACKGROUND

More complex cases are being performed robotically. This study aims to characterize trends in robotic pancreatoduodenectomy (RPD) over time and assess opportunities for advanced trainees.

METHODS

Using the ACS-NSQIP database from 2014 to 2019, PD cases were characterized by operative approach (open-OPN, laparoscopic-LAP, robotic-ROB). Proficiency and postoperative outcomes were described by approach over time.

RESULTS

24,268 PDs were identified, with the ROB approach increasing from 2.8% to 7.5%. Unplanned conversion increased over time for LAP (27.7-39.0%, p = 0.003) but was unchanged for ROB cases (14.8-14.7%, p = 0.257). Morbidity increased for OPN PD (35.5-36.8%, p = 0.041) and decreased for ROB PD (38.7-30.3%, p = 0.010). Mean LOS was lower in ROB than LAP/OPN (9.5 vs. 10.9 vs. 10.9 days, p < 0.00001). Approximately, 100 AHPBA, SSO, and ASTS fellows are being trained each year in North America; however, only about 5 RPDs are available per trainee per year which is far below that recommended to achieve proficiency.

CONCLUSION

Over a 6-year period, a significant increase was observed in the use of RPD without a concomitant increase in conversion rates. RPD was associated with decreased morbidity and length of stay. Despite this shift, the number of cases being performed is not adequate for all fellows to achieve proficiency before graduation.
