Abstract
AbstractWhile robotic procedures are growing rapidly, medical students have a limited role in robotic surgeries. Curricula are needed to enhance engagement. We examined feasibility of augmenting Intuitive Surgical (IS) robotic training for medical students. As a pilot, 18 senior students accepted an invitation to a simulation course with a daVinci robot trainer. Course teaching objectives included introducing robotic features, functionalities, and roles. A 1-h online module from the IS learning platform and a 4-h in-person session comprised the course. The in-person session included an overview of the robot by an IS trainer (1.5 h), skills practice at console (1.5 h), and a simulation exercise focused on the bedside assist role (1 h). Feasibility included assessing implementation and acceptability using a post-session survey and focus group (FG). Survey responses were compiled. FG transcripts were analyzed using inductive thematic analysis techniques. Fourteen students participated. Implementation was successful as interested students signed up and completed each of the course components. Regarding acceptability, students reported the training valuable and recommended it as preparation for robotic cases during core clerkships and sub-internships. In addition, FGs revealed 4 themes: (1) perceived expectations of students in the OR; (2) OR vs. outside-OR learning; (3) simulation of stress; and (4) opportunities to improve the simulation component. To increase preparation for the robotic OR and shift robotic training earlier in the surgical education continuum, educators should consider hands-on simulation for medical students. We demonstrate feasibility although logistics may limit scalability for large numbers of students.

Abstract
OBJECTIVE Camera assistance is important for proper visualization of the operative field in laparoscopic surgery. Navigation grid (NG) has been designed to help the camera assistants focus the camera on the target operative field. This is a randomized, controlled trial to study the effect of the NG on performance of camera assistants. DESIGN Minimally invasive operations were randomized (1:1) to either with or without use of NG for the camera assistant. The operations were recorded and the time spent inside and outside of the target area were reported. SETTING A tertiary care teaching hospital. RESULTS Fifty-eight operations (30 with and 28 without NG) were recorded. Sixteen camera assistants participated. Time spent outside the target area was significantly less with the use of NG (64.5 ± 63 seconds vs 396 ± 226.5 seconds; p < 0.0001). This impact of NG on performance of the camera assistants was significant regardless of their level of training. CONCLUSIONS NG improved performance of the camera assistant during laparoscopic abdominal procedures. This is a feasible tool that can help camera holders better assist the operating surgeons.

Abstract
Background The key for conducting thymectomy by thoracoscope is the treatment of thymic veins, as they are the most common source of bleeding. The traditional treatment is to cut off the distal and proximal vessels after Ham-Lock clamping. Our team found that it is safe and reliable to use ultrasonic energy to cut off thymic veins in previous open operations. This study aimed to investigate the feasibility and safety of thymic vein sealing with ultrasonic energy in video-assisted thoracoscopic surgery (VATS) thymectomy. Methods A total of 169 patients with or without thymic tumors who underwent thymectomy by thoracoscope were enrolled in the study. Among them, group A, with 89 patients, underwent thoracoscopic thymic vein resection by Ham-Lock, and group B, with 80 patients, did so by ultrasonic energy. The groups were compared in terms of the characteristics of patients, tumors, and perioperative period. Results There were no significant differences in patients' characteristics between the two groups (P>0.05). There was no significant difference between the two groups in blood transfusion, operation time, drainage, and hospitalization (P>0.05). There were no deaths, secondary operation and post-operative blood transfusion, and no serious complications leading to prolonged hospitalization. One patient in group A was converted to thoracotomy due to left anonymous venous hemorrhage, and one patient in group B had thymic venous hemorrhage, but the hemorrhage was successfully stopped under thoracoscope. Conclusions In VATS thymectomy (with or without thymic tumors), there is no significant difference in the treatment of thymic veins between Ham-Lock clipping and ultrasonic energy in conversion to open surgery in regards to thymic venous hemorrhage, postoperative drainage, blood transfusion, operation time, drainage, and hospital stay. Use of ultrasonic energy is a safe and reliable method for thymic vein disconnection.

Abstract
BACKGROUND The fundamentals of laparoscopic surgery (FLS) trainer box, which is now established as a standard for evaluating minimally invasive surgical skills, consists of five tasks: peg transfer, pattern cutting, ligation, intra- and extracorporeal suturing. Virtual simulators of these tasks have been developed and validated as part of the Virtual Basic Laparoscopic Skill Trainer (VBLaST) (Arikatla et al. in Int J Med Robot Comput Assist Surg 10:344-355, 2014; Zhang et al. in Surg Endosc 27(10):3603-3615, 2013; Sankaranarayanan et al. in J Laparoendosc Adv Surg Tech 20(2):153-157, 2010; Qi et al. J Biomed Inform 75:48-62, 2017). The virtual task trainers have many advantages including automatic real-time objective scoring, reduced costs, and eliminating human proctors. In this paper, we extend VBLaST by adding two camera navigation system tasks: (a) pattern matching and (b) path tracing. METHODS A comprehensive camera navigation simulator with two virtual tasks, simplified and cheaper hardware interface (compared to the prior version of VBLaST), graphical user interface, and automated metrics has been designed and developed. Face validity of the system is tested with medical students and residents from the University at Buffalo's medical school. RESULTS The subjects rated the simulator highly in all aspects including its usefulness in training to center the target and to teach sizing skills. The quality and usefulness of the force feedback scored the lowest at 2.62.

Abstract
OBJECTIVES To determine the influence of age, year of graduation, and video game experience on baseline laparoscopic psychomotor skills. STUDY DESIGN Cross-sectional. SAMPLE POPULATION Licensed veterinarians (n = 38) and registered veterinary technicians (VTs) (n = 49). METHODS A laparoscopic box trainer was set up at the 2016 Ontario Veterinary Medical Association (OVMA) and the 2016 Ontario Association of Veterinary Technicians (OAVT) conferences held in Toronto, Ontario, Canada. Participants volunteered to perform a single repetition of a peg transfer (PT) exercise. Participants were given a short demonstration of the PT task prior to testing. A Spearman's rank correlation (rs ) was used to identify associations between baseline psychomotor skills and self-reported surgical and non-surgical experiences collected via survey. Mann-Whitney U tests were used to compare PT scores in veterinarians and VTs. A P-value of < .05 was considered significant. RESULTS The mean age of participants was 36 years (range 21-67) and the majority were female (83%). In veterinarians, PT scores were highest in the most recent graduates (P = .01, rs = 0.42), and PT scores increased with self-reported VG experience (P = .02, rs = 0.38). PT scores correlated inversely with age (P = .02, rs = -0.37). No associations were observed in VTs (P > .05). Veterinary technicians that frequently used chopsticks scored higher than those without chopstick experience (P = .04). CONCLUSIONS Age and year of graduation correlated inversely, while self-reported VG experience correlated positively with laparoscopic psychomotor skills of veterinarians, when assessed on a simulator. The use of chopsticks may contribute to the acquisition of psychomotor skills in VTs.

Development of a novel simulation model for assessment of laparoscopic camera navigation. Surg Endosc 2016; 31:3033-3039. [PMID: 27826776 DOI: 10.1007/s00464-016-5323-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2016] [Accepted: 10/31/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Laparoscopic camera navigation is vital to laparoscopic surgery, yet often falls to the most junior member of the surgical team who has limited laparoscopic operating experience. Previously published reports on simulation models fail to address qualitative scoring of movement, method of communication and correct physician location with respect to patient position. The purpose of this study was to develop and evaluate a novel laparoscopic camera navigation simulation model that addresses these deficiencies. METHODS A novel, low-cost laparoscopic camera navigational maze was constructed from pliable foam for use in a standard laparoscopic surgery box trainer. Participants (n = 37) completed a camera navigation exercise by following a pre-recorded set of verbal instructions using correct anatomic terminology that is used in the operating room, to simulate an actual operating room experience of receiving verbal cues from senior surgeons. The sample group consisted of participants at various levels of Obstetrics and Gynecology training, representing novice to expert laparoscopists. Each trial was recorded with a multi-channel video camera. Performances were scored by a blinded evaluator for excess gross and fine camera movements as well as overt errors, including camera collisions and failure to follow directions. RESULTS Our model demonstrated evidence of validity by discriminating performance by level of laparoscopic experience with a statistically significant decrease in number of movements and errors in experts compared to novices. A trend emerged toward improvement with each additional year of training, with reduced variability among performances in more experienced participants. CONCLUSIONS This novel, low-cost box-trainer simulation model for laparoscopic camera navigation offers a mechanism for assessment of laparoscopic camera operation skills. Moreover, this model closely replicates operating room logistics and communication. Given the necessity for improved laparoscopic camera operation education, our model represents a unique, complementary tool to other laparoscopic simulation curricula.

Abstract
BACKGROUND Inexperienced operating assistants are often tasked with the important role of handling camera navigation during laparoscopic surgery. Incorrect handling can lead to poor visualization, increased operating time, and frustration for the operating surgeon-all of which can compromise patient safety. The objectives of this trial were to examine how to train laparoscopic camera navigation and to explore the transfer of skills to the operating room. MATERIALS AND METHODS A randomized, single-center superiority trial with three groups: The first group practiced simulation-based camera navigation tasks (camera group), the second group practiced performing a simulation-based cholecystectomy (procedure group), and the third group received no training (control group). Participants were surgical novices without prior laparoscopic experience. The primary outcome was assessment of camera navigation skills during a laparoscopic cholecystectomy. The secondary outcome was technical skills after training, using a previously developed model for testing camera navigational skills. The exploratory outcome measured participants' motivation toward the task as an operating assistant. RESULTS Thirty-six participants were randomized. No significant difference was found in the primary outcome between the three groups (p = 0.279). The secondary outcome showed no significant difference between the interventions groups, total time 167 s (95% CI, 118-217) and 194 s (95% CI, 152-236) for the camera group and the procedure group, respectively (p = 0.369). Both interventions groups were significantly faster than the control group, 307 s (95% CI, 202-412), p = 0.018 and p = 0.045, respectively. On the exploratory outcome, the control group for two dimensions, interest/enjoyment (p = 0.030) and perceived choice (p = 0.033), had a higher score. CONCLUSIONS Simulation-based training improves the technical skills required for camera navigation, regardless of practicing camera navigation or the procedure itself. Transfer to the clinical setting could, however, not be demonstrated. The control group demonstrated higher interest/enjoyment and perceived choice than the camera group.

Abstract
Background Effective visualization of the operative field is vital to surgical safety and education. However, additional metrics for visualization are needed to complement other common measures of surgeon proficiency, such as time or errors. Unlike other surgical modalities, robot-assisted minimally invasive surgery (RAMIS) enables data-driven feedback to trainees through measurement of camera adjustments. The purpose of this study was to validate and quantify the importance of novel camera metrics during RAMIS. Methods New (n = 18), intermediate (n = 8), and experienced (n = 13) surgeons completed 25 virtual reality simulation exercises on the da Vinci Surgical System. Three camera metrics were computed for all exercises and compared to conventional efficiency measures. Results Both camera metrics and efficiency metrics showed construct validity (p < 0.05) across most exercises (camera movement frequency 23/25, camera movement duration 22/25, camera movement interval 19/25, overall score 24/25, completion time 25/25). Camera metrics differentiated new and experienced surgeons across all tasks as well as efficiency metrics. Finally, camera metrics significantly (p < 0.05) correlated with completion time (camera movement frequency 21/25, camera movement duration 21/25, camera movement interval 20/25) and overall score (camera movement frequency 20/25, camera movement duration 19/25, camera movement interval 20/25) for most exercises. Conclusions We demonstrate construct validity of novel camera metrics and correlation between camera metrics and efficiency metrics across many simulation exercises. We believe camera metrics could be used to improve RAMIS proficiency-based curricula.

Abstract
胸外科手术技术已发生革命性变化,胸腔镜手术(video-assisted thoracic surgery, VATS)已经、正在成为各类胸部手术的主流方式。安全、高质、艺术化的VATS离不开扶镜手与术者默契的团队配合,如果说优秀的开放手术是术者脑、眼、手、体并用并无缝连接的整体配合的结果,那么,VATS的扶镜手则担负着两个人的眼睛,即本人和术者,这比照顾一个人脑、眼、手、体更为精细,更为困难。当然,优秀的扶镜手必将成长为不久将来优秀的术者。

Abstract
Introduction: This systematic review was conducted to analyze the impact and describe simulation-based training and the acquisition of laparoscopic surgery skills during medical school and residency programs. Methods: This systematic review focused on the published literature that used randomized controlled trials to examine the effectiveness of simulation-based training to develop laparoscopic surgery skills. Searching PubMed from the inception of the databases to May 1, 2014 and specific hand journal searches identified the studies. This current review of the literature addresses the question of whether laparoscopic simulation translates the acquisition of surgical skills to the operating room (OR). Results: This systematic review of simulation-based training and laparoscopic surgery found that specific skills could be translatable to the OR. Twenty-one studies reported learning outcomes measured in five behavioral categories: economy of movement (8 studies); suturing (3 studies); performance time (13 studies); error rates (7 studies), and global rating (7 studies). Conclusion: Simulation-based training can lead to demonstrable benefits of surgical skills in the OR environment. This review suggests that simulation-based training is an effective way to teach laparoscopic surgery skills, increase translation of laparoscopic surgery skills to the OR, and increase patient safety; however, more research should be conducted to determine if and how simulation can become apart of surgical curriculum.

Abstract
AIM To assess where we currently stand in relation to simulator-based training within modern surgical training curricula. METHODS A systematic literature search was performed in PubMed database using keywords "simulation", "skills assessment" and "surgery". The studies retrieved were examined according to the inclusion and exclusion criteria. Time period reviewed was 2000 to 2013. The methodology of skills assessment was examined. RESULTS Five hundred and fifteen articles focussed upon simulator based skills assessment. Fifty-two articles were identified that dealt with technical skills assessment in general surgery. Five articles assessed open skills, 37 assessed laparoscopic skills, 4 articles assessed both open and laparoscopic skills and 6 assessed endoscopic skills. Only 12 articles were found to be integrating simulators in the surgical training curricula. Observational assessment tools, in the form of Objective Structured Assessment of Technical Skills (OSATS) dominated the literature. CONCLUSION Observational tools such as OSATS remain the top assessment instrument in surgical training especially in open technical skills. Unlike the aviation industry, simulation based assessment has only now begun to cross the threshold of incorporation into mainstream skills training. Over the next decade we expect the promise of simulator-based training to finally take flight and begin an exciting voyage of discovery for surgical trainees.

JOURNAL OF SURGICAL EDUCATION 2014; 71:187-192. [PMID: 24602708 DOI: 10.1016/j.jsurg.2013.07.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/11/2013] [Revised: 06/23/2013] [Accepted: 07/08/2013] [Indexed: 06/03/2023]
Abstract
OBJECTIVES Surgical interns are often not well prepared and have high anxiety about the execution of basic technical skills. This study investigates whether a short preclinical course focusing on laparoscopic camera-navigating skills is useful in the preparation for internship. DESIGN Through randomization, an experimental group who attended a short laparoscopic training session and a control group were created. Students' interest for this training and their confidence for laparoscopic exposure during surgical internship were inquired. During internship, camera-navigating skills were assessed by the operating surgeons (using a validated global rating scale) as well as by the students themselves (using a 10-points Likert scale). SETTING All research was performed in the Center for Surgical Technologies, Leuven, Belgium. PARTICIPANTS A total of 205 fifth-year medical students at the University of Leuven, Belgium. RESULTS Of the control group students, 80% were interested in attending the training session. There was no difference in confidence between experimental and control group. According to the surgeons and students, there was a significant improvement in clinical performance from the first (scores on global rating and Likert scales ±50%) to the last procedure (scores ±70%) for both groups. However, there was no difference in performance between groups. CONCLUSIONS Students are very interested in attending a preclinical laparoscopic training session. However, trained students did not display higher confidence or better clinical performance during internship. Even without previous training, students are fast to acquire the necessary skills during surgical internship.

Abstract
BACKGROUND Surgical training has traditionally been one of apprenticeship, where the surgical trainee learns to perform surgery under the supervision of a trained surgeon. This is time consuming, costly, and of variable effectiveness. Training using a box model physical simulator - either a video box or a mirrored box - is an option to supplement standard training. However, the impact of this modality on trainees with no prior laparoscopic experience is unknown. OBJECTIVES To compare the benefits and harms of box model training versus no training, another box model, animal model, or cadaveric model training for surgical trainees with no prior laparoscopic experience. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and Science Citation Index Expanded to May 2013. SELECTION CRITERIA We included all randomised clinical trials comparing box model trainers versus no training in surgical trainees with no prior laparoscopic experience. We also included trials comparing different methods of box model training. DATA COLLECTION AND ANALYSIS Two authors independently identified trials and collected data. We analysed the data with both the fixed-effect and the random-effects models using Review Manager for analysis. For each outcome, we calculated the standardised mean difference (SMD) with 95% confidence intervals (CI) based on intention-to-treat analysis whenever possible. MAIN RESULTS Twenty-five trials contributed data to the quantitative synthesis in this review. All but one trial were at high risk of bias. Overall, 16 trials (464 participants) provided data for meta-analysis of box training (248 participants) versus no supplementary training (216 participants). All the 16 trials in this comparison used video trainers. Overall, 14 trials (382 participants) provided data for quantitative comparison of different methods of box training. There were no trials comparing box model training versus animal model or cadaveric model training. Box model training versus no training: The meta-analysis showed that the time taken for task completion was significantly shorter in the box trainer group than the control group (8 trials; 249 participants; SMD -0.48 seconds; 95% CI -0.74 to -0.22). Compared with the control group, the box trainer group also had lower error score (3 trials; 69 participants; SMD -0.69; 95% CI -1.21 to -0.17), better accuracy score (3 trials; 73 participants; SMD 0.67; 95% CI 0.18 to 1.17), and better composite performance scores (SMD 0.65; 95% CI 0.42 to 0.88). Three trials reported movement distance but could not be meta-analysed as they were not in a format for meta-analysis. There was significantly lower movement distance in the box model training compared with no training in one trial, and there were no significant differences in the movement distance between the two groups in the other two trials. None of the remaining secondary outcomes such as mortality and morbidity were reported in the trials when animal models were used for assessment of training, error in movements, and trainee satisfaction. Different methods of box training: One trial (36 participants) found significantly shorter time taken to complete the task when box training was performed using a simple cardboard box trainer compared with the standard pelvic trainer (SMD -3.79 seconds; 95% CI -4.92 to -2.65). There was no significant difference in the time taken to complete the task in the remaining three comparisons (reverse alignment versus forward alignment box training; box trainer suturing versus box trainer drills; and single incision versus multiport box model training). There were no significant differences in the error score between the two groups in any of the comparisons (box trainer suturing versus box trainer drills; single incision versus multiport box model training; Z-maze box training versus U-maze box training). The only trial that reported accuracy score found significantly higher accuracy score with Z-maze box training than U-maze box training (1 trial; 16 participants; SMD 1.55; 95% CI 0.39 to 2.71). One trial (36 participants) found significantly higher composite score with simple cardboard box trainer compared with conventional pelvic trainer (SMD 0.87; 95% CI 0.19 to 1.56). Another trial (22 participants) found significantly higher composite score with reverse alignment compared with forward alignment box training (SMD 1.82; 95% CI 0.79 to 2.84). There were no significant differences in the composite score between the intervention and control groups in any of the remaining comparisons. None of the secondary outcomes were adequately reported in the trials. AUTHORS' CONCLUSIONS The results of this review are threatened by both risks of systematic errors (bias) and risks of random errors (play of chance). Laparoscopic box model training appears to improve technical skills compared with no training in trainees with no previous laparoscopic experience. The impacts of this decreased time on patients and healthcare funders in terms of improved outcomes or decreased costs are unknown. There appears to be no significant differences in the improvement of technical skills between different methods of box model training. Further well-designed trials of low risk of bias and random errors are necessary. Such trials should assess the impacts of box model training on surgical skills in both the short and long term, as well as clinical outcomes when the trainee becomes competent to operate on patients.

Abstract
Background. Untrained laparoscopic camera assistants in minimally invasive surgery (MIS) may cause suboptimal view of the operating field, thereby increasing risk for errors. Camera navigation is often performed by the least experienced member of the operating team, such as inexperienced surgical residents, operating room nurses, and medical students. The operating room nurses and medical students are currently not included as key user groups in structured laparoscopic training programs. A new virtual reality laparoscopic camera navigation (LCN) module was specifically developed for these key user groups. Methods. This multicenter prospective cohort study assesses face validity and construct validity of the LCN module on the Simendo virtual reality simulator. Face validity was assessed through a questionnaire on resemblance to reality and perceived usability of the instrument among experts and trainees. Construct validity was assessed by comparing scores of groups with different levels of experience on outcome parameters of speed and movement proficiency. Results. The results obtained show uniform and positive evaluation of the LCN module among expert users and trainees, signifying face validity. Experts and intermediate experience groups performed significantly better in task time and camera stability during three repetitions, compared to the less experienced user groups ( P < .007). Comparison of learning curves showed significant improvement of proficiency in time and camera stability for all groups during three repetitions ( P < .007). Conclusion. The results of this study show face validity and construct validity of the LCN module. The module is suitable for use in training curricula for operating room nurses and novice surgical trainees, aimed at improving team performance in minimally invasive surgery.

Abstract
Surgery plays a prominent role in healthcare worldwide. It has been estimated that the rate of fatal events occurring in surgery is about one in ten thousand exposures and up to one million deaths per year. Most errors are caused by failure of non-technical skills. The WHO surgical safety checklist has shown that patient safety could be improved by using a simple and effective method. However, achieving high compliance requires research, training and local adaptation.
