Abstract
BACKGROUND Microsurgical techniques have a steep learning curve. We adapted validated surgical approaches to develop a novel, competency-based microsurgical simulation curriculum called Fundamentals of Microsurgery (FMS). The purpose of this study is to present our experience with FMS and quantify the effect of the curriculum on resident performance in the operating room. METHODS Trainees underwent the FMS curriculum requiring task progression: (1) rubber band transfer, (2) coupler tine grasping, (3) glove laceration repair, (4) synthetic vessel anastomosis, and (5) vessel anastomosis in a deep cavity. Resident anastomoses were also evaluated in the operative room with the Stanford Microsurgery and Resident Training (SMaRT) tool to evaluate technical performance. The National Aeronautics and Space Administration Task Load Index (NASA-TLX) and Short-Form Spielberger State-Trait Anxiety Inventory (STAI-6) quantified learner anxiety and workload. RESULTS A total of 62 anastomoses were performed by residents in the operating room during patient care. Higher FMS task completion showed an increased mean SMaRT score (p = 0.05), and a lower mean STAI-6 score (performance anxiety) (p = 0.03). Regression analysis demonstrated residents with higher SMaRT score had lower NASA-TLX score (mental workload) (p < 0.01) and STAI-6 scores (p < 0.01). CONCLUSION A novel microsurgical simulation program FMS was implemented. We found progression of trainees through the program translated to better technique (higher SMaRT scores) in the operating room and lower performance anxiety on STAI-6 surveys. This suggests that the FMS curriculum improves proficiency in basic microsurgical skills, reduces trainee mental workload, anxiety, and improves intraoperative clinical proficiency.

Abstract
INTRODUCTION There has been an overall growth of 462% in laparoscopic procedures performed by surgical residents between 2000 and 2018. Therefore, training courses in laparoscopic surgery are advocated in many postgraduate programs. While the immediate effect is determined in some cases, the retention of acquired skills is rarely investigated. The objective of this study was to objectively measure the retention of laparoscopic technical skills to offer a more personalized training program. METHODS First year general surgery residents performed two fundamental laparoscopic skills tasks (Post and Sleeve and the ZigZag loop) on the Lapron box trainer. Assessment was performed before, directly after, and 4 months after completing the basic laparoscopy course. Force, motion, and time were the measured variables. RESULTS A total of 29 participants were included from 12 Dutch training hospitals and 174 trials were analyzed. The 4 months assessment of the Post and Sleeve showed a significant improvement in force ( P= 0.004), motion ( P ≤0.001), and time ( P ≤0.001) compared to the baseline assessment. The same was true for the ZigZag loop: force ( P ≤0.001), motion ( P= 0.005), and time ( P ≤0.001).Compared to the 4 months assessment, skill deterioration was present for the Post and Sleeve in the mean force ( P= 0.046), max impulse ( P= 0.12), and time ( P= 0.002). For the ZigZag loop, skill decay was observed for force ( P= 0.021), motion ( P= 0.015), and time ( P ≤0.001) parameters. CONCLUSION Acquired laparoscopic technical skills decreased 4 months after the basic laparoscopy course. Compared to baseline performance, participants showed significant improvement, however deterioration was observed compared to postcourse measurements. To preserve acquired laparoscopic skills, it is recommended to incorporate maintenance training, preferably with objective parameters, in training curricula.

Abstract
Introduction: Acquiring and retaining minimally invasive surgery (MIS) skills may be aided by using MIS take-home box simulators. This study aims to evaluate the use of a take-home MIS box trainer for training sessions at-home. Methods: Trainees who previously bought the LaparoscopyBoxx (between 2016 and 2020) were asked to complete an online questionnaire. The first part was on their demographic data, and the second part was on their use and opinion on the box trainer (on a 5-point Likert scale). Results: A total of 39 participants (9 surgeons and 30 trainees) completed the questionnaire (response rate 40%). Overall, participants had a positive opinion on the use of the box trainer and would recommend it to others for training (mean 4.2). Basic tasks, such as needle trail and ring transfer, were practiced most often and were regarded most relevant (mean 4.1-4.3). They regarded practicing on the stimulator of added value to practicing in the clinic (mean 4.2), were more confident during clinical procedures (mean 3.9), and felt that their skills had improved (mean 4.1). Of quarter of the participants who bought the MIS box trainer during the COVID-19 pandemic reported an increased use during times of less clinical exposure. Conclusion: Surgeons and trainees have a positive opinion on using a take-home MIS box trainer for at-home training for general as well as for pediatric MIS skills. Especially during periods of less exposure in the clinical setting and less hands-on courses, such as during the COVID-19 pandemic, at-home training may be a valuable addition.

Abstract
Robotic surgery training has lacked evidence-based standardisation. We aimed to determine the effectiveness of adjunctive interactive virtual classroom training (VCT) in concordance with the self-directed Fundamentals of Robotic Surgery (FRS) curriculum. The virtual classroom is comprised of a studio with multiple audio–visual inputs to which participants can connect remotely via the BARCO weConnect platform. Eleven novice surgical trainees were randomly allocated to two training groups (A and B). In week 1, both groups completed a robotic skills induction. In week 2, Group A received training with the FRS curriculum and adjunctive VCT; Group B only received access to the FRS curriculum. In week 3, the groups received the alternate intervention. The primary outcome was measured using the validated robotic-objective structured assessment of technical skills (R-OSAT) at the end of week 2 (time-point 1) and 3 (time-point 2). All participants completed the training curriculum and were included in the final analyses. At time-point 1, Group A achieved a statistically significant greater mean proficiency score compared to Group B (44.80 vs 35.33 points, p = 0.006). At time-point 2, there was no significant difference in mean proficiency score in Group A from time-point 1. In contrast, Group B, who received further adjunctive VCT showed significant improvement in mean proficiency by 9.67 points from time-point 1 (95% CI 5.18–14.15, p = 0.003). VCT is an effective, accessible training adjunct to self-directed robotic skills training. With the steep learning curve in robotic surgery training, VCT offers interactive, expert-led learning and can increase training effectiveness and accessibility.

Abstract
INTRODUCTION Sufficient training is needed to acquire and retain the procedural skills needed for the surgical correction of congenital anatomical malformations. This study aims to assess the opinions of trainees and pediatric surgeons on the use of simulation-based continued at-home training, which can help to acquire these skills. METHODS This study consisted of two parts. First, an international survey among trainees and pediatric surgeons assessed their opinions on simulation-based at-home training for pediatric surgical procedures (5-point Likert scale). Second, participants of pediatric colorectal courses were instructed to practice the posterior sagittal anorectoplasty procedure at-home on a simulation model and, subsequently, complete a questionnaire regarding their opinions on continuous at-home training (5-point Likert scale). RESULTS A total of 163 participants (83% pediatric surgeons) completed the international survey (response rate 43%). Overall, participants considered the training useful for both laparoscopic (mean 4.7) and open procedures (mean 4.2) and agreed that it may be used at home after a hands-on course (mean 4.3).Twenty participants completed the questionnaire on continued training (response rate 36%). All agreed that at-home training was of added value (mean 4.5) and that the skills were transferable to the clinical setting (mean 4.3). At-home training was regarded a suitable exercise after a hands-on workshop (mean 4.3), but less so without a workshop (mean 3.7, p=0.017). CONCLUSION Participating trainees and pediatric surgeons were of the opinion that simulation models and at-home training have added value. This implies that simulation-based training may be used more often in pediatric surgical training.

The Spaced Learning Concept Significantly Improves Acquisition of Laparoscopic Suturing Skills in Students and Residents: A Randomized Control Trial. Eur J Pediatr Surg 2021; 31:518-524.

Abstract
INTRODUCTION Spaced learning consists of blocks with highly condensed content that interrupted by breaks during which distractor activities, such as physical activity, are performed. The concept has been shown to be superior in complex motor skill acquisition like laparoscopic suturing and knot tying. Preliminary studies have solely been conducted with medical students. Therefore, it remained unanswered if the spaced learning concept would also work for pediatric surgery residents. MATERIALS AND METHODS The study aimed to evaluate the effectiveness of spaced learning, students, and residents were asked to perform four surgeons' square knots on a bowel model within 30 minutes prior and post 3 hours of hands-on training. To examine the long-term skills, the same subjects were asked to perform a comparable, but more complex task 12 months later without receiving training in the meantime. Total time, knot stability, suture accuracy, knot quality, and laparoscopic performance were assessed. Additionally, motivation was accessed by using the questionnaire on current motivation. Differences were calculated using mixed analysis of variance, Mann-Whitney U test, and multivariate analysis of covariance. RESULTS A total of 20 medical students and 14 residents participated in the study. After randomization, 18 were trained using the spaced learning concept and 16 via conventional methods. Both groups had comparable baseline characteristics and improved significantly after training in all assessed measures. The spaced learning concept improved procedure performance as well as knot quality and stability in both students and residents. However, residents that trained via spaced learning showed significantly better long-term results regarding knot quality and speed in comparison to students. Although anxiety was significantly reduced in both training groups over time, residents were significantly more interested regarding knot tying than students. CONCLUSION This study dispels any remaining doubt that the spaced learning concept might only work for medical students. It appears that the spaced learning concept is very suitable for residents in acquiring complex motor skills. It is superior to conventional training, resulting in improved procedural performance as well as knot quality and speed. Hence, tailored training programs should not only be integrated early on in students' curricula but also in surgical training programs.

Correlation of surgical case volume and fellowship training with performance on simulated procedural tasks. Am J Obstet Gynecol 2021; 225:548.e1-548.e10. [PMID: 34147495 DOI: 10.1016/j.ajog.2021.06.062] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 06/02/2021] [Accepted: 06/14/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND High-volume and fellowship-trained surgeons have superior outcomes. However, in gynecology, a large proportion of cases are performed by low-volume surgeons. Simulation has been shown to be useful in assessing surgical skill and may be a useful tool in hospital credentialing and maintenance of privileges. OBJECTIVE To determine the correlation between a surgical case volume and fellowship training with performance on simulated procedural tasks. STUDY DESIGN A total of 108 obstetricians and gynecologists with laparoscopic privileges at 2 academic institutions completed a pre-test survey and performed 3 tasks on the LapSim laparoscopic virtual reality simulator. The pre-test survey inquired about the monthly laparoscopic case volume and prior training. Simulations included a basic skills task (peg transfer) followed by a procedural task (salpingectomy) of 2 difficulty levels (low and moderate). Spearman correlation and Wilcoxon tests were used to determine correlations between the survey responses and performance metrics. RESULTS Participants included 67 generalists (62%) and 41 fellowship-trained specialists (38%). There was an observed weak correlation among surgical volume (more than 6 cases per month), time to completion, and the amount of blood loss when performing the low-difficulty level salpingectomy (r=-0.32, P=.0007 and r=-0.29, P=.002, respectively). The economy of movement (instrument path length) was correlated to high surgical volume (r=-0.35, P=.0002). Compared with generalists, surgeons with fellowship training performed tasks faster (410.8 seconds [interquartile range, 309.7-595.2]) vs 530.2 seconds (interquartile range, 406.2-605.0; P=.0009), more efficiently at 6.1 m (interquartile range, 4.8-7.3) vs 8.1 m (interquartile range, 5.8-10.7; P=.0003), and with less blood loss at 21.7 mL (interquartile range, 11.8-37.7) vs 42.9 mL (interquartile range, 18.1-70.6; P=.002). Regarding the case volume and fellowship background, there was no difference in ovarian diathermy damage. In addition, there was no difference among most performance parameters for the peg transfer task and the moderate-difficulty salpingectomy procedure. CONCLUSION Surgical experience obtained through higher case volume and fellowship training correlate with higher performance scores during simulated procedural tasks. In a previous study, we found a similar correlation with simulated basic skills tasks. The current study is a continuation of an ongoing quality initiative to establish a summative assessment of laparoscopic surgical skills using virtual reality simulator for the maintenance of credentials among obstetrical and gynecologic surgeons. Future studies will compare the performance metrics from laparoscopic procedures performed on virtual reality simulator with the performance in the operating room and clinical outcomes.

Abstract
BACKGROUND Adaptive training is an approach in which training variables change with the needs and traits of individual trainees. It has potential to mitigate the effect of personality traits such as impulsiveness on surgical performance. Selective performance feedback is one way to implement adaptive training. This paper investigates whether selective feedback can direct performance of trainees of either high- or low impulsiveness. METHODS A total of 83 inexperienced medical students of known impulsiveness performed a four-session laparoscopic training course on a Virtual Reality Simulator. They performed two identical series of tasks every session. During one series of tasks they received performance feedback on duration and during the other series they received feedback on damage. Performance parameters (duration and damage) were compared between the two series of tasks to assess whether selective performance feedback can be used to steer emphasis in performance. To assess the effectiveness of selective feedback for people of high- or low impulsiveness, the difference in performance between the two series for both duration and damage was also assessed. RESULTS Participants were faster when given performance feedback for speed for all exercises in all sessions (average z-value = - 4.14, all p values < .05). Also, they performed better on damage control when given performance feedback for damage in all tasks and during all sessions except for one (average z-value = - 4.19, all but one p value < .05). Impulsiveness did not impact the effectiveness of selective feedback. CONCLUSION Selective feedback on either duration or damage can be used to improve performance for the variable that the trainee receives feedback on. Trainee impulsiveness did not modulate this effect. Selective feedback can be used to steer training focus in adaptive training systems and can mitigate the negative effects of impulsiveness on damage control.

Abstract
BACKGROUND The objectives of this study were to investigate the relationship between the acquisition of laparoscopic suturing skills and other operative laparoscopic skills and to provide evidence to determine ideal time and duration to introduce laparoscopic suturing training. METHODS The first part of the study explored the relationship between the acquisition of laparoscopic suturing skills and proficiency of other operative laparoscopic skills. The second part of the study consisted of an opinion survey from senior and junior trainees on aspects of training in laparoscopic suturing. RESULTS One hundred twenty-eight surgical trainees participated in this study. The total scores of task performance of 57 senior surgical trainees in laparoscopic suturing skills consisting of needle manipulation and intracoporeal knot tying were improved significantly after the training course (46.9 ± 5.3 vs 29.5 ± 9.4, P < .001), the improvement rate was 59%. No statistically significant correlations were observed between intracorporeal laparoscopic suturing skills and proficiency in the basic laparoscopic manipulative skills assessed before (r = 0.193; P = 0.149) and after (r = 0.024; P = 0.857) the training course. 91% of senior trainees and 94% junior trainees expressed that intracorporeal suturing should be introduced at an early stage of the training curriculum. CONCLUSIONS There was no statistically significant correlation between the performance on basic operative laparoscopic skills (non-suturing skills) and laparoscopic suturing skills observed in this study. The acquisition of basic laparoscopic skills is not a prerequisite for training in intracorporeal suturing and it may be beneficial for the surgical trainees to learn this skill early in the surgical training curriculum. Surgical trainees want to learn and practice laparoscopic suturing earlier than later in their training.

Abstract
BACKGROUND Little is known about the relation between impulsiveness and surgical performance even though research in similar high-risk/high-skills shows evidence of more hazardous behavior by impulsive professionals. We investigated the impact of impulsiveness on laparoscopic simulator performance. METHODS Eighty-three subjects participated in a four-session laparoscopic training course. Based on the Eysenck Personality test, we created equal sized high- and low impulsiveness groups and compared task duration and errors on tasks for two laparoscopic simulators. RESULTS The low impulsiveness group outperformed the high impulsiveness group on damage on the LapSim virtual reality trainer (U = 459, p < .049), and showed a trend towards better error performance on the FLS videotrainer. We found no differences on task duration. CONCLUSIONS In surgical simulation training, high impulsiveness is associated with creating more damage, but not with faster performance. Time needed to correct errors may have obscured faster performance in the high impulsiveness group. SUMMARY FOR THE TABLE OF CONTENTS Subjects were divided into high- and low impulsiveness groups based on the Eysenck Impulsiveness Inventory test. Performance (time and errors) were compared between groups for tasks on the LapSim virtual reality trainer and FLS videotrainer. Low impulsive subjects outperformed high impulsive subjects on errors.

Kim TE, Tsui BCH. Simulation-based ultrasound-guided regional anesthesia curriculum for anesthesiology residents. Korean J Anesthesiol 2018; 72:13-23. [PMID: 30481945 PMCID: PMC6369343 DOI: 10.4097/kja.d.18.00317] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Accepted: 11/27/2018] [Indexed: 01/22/2023] Open
Abstract
Proficiency in ultrasound-guided regional anesthesia (UGRA) requires the practitioner to acquire cognitive and technical skills. For anesthesiology residents, an assortment of challenges has been identified in learning UGRA skills. Currently, a validated UGRA curriculum for residents does not exist, and the level of UGRA proficiency achieved during residency training can vary considerably. Simulated practice has been shown to enhance proficiency in UGRA, and a competency-based education with simulation training has been endorsed for anesthesiology residents. The objective of this review is to outline simulation-based training that can be implemented in a UGRA curriculum and to explore educational tools like gamification to facilitate competency in regional anesthesiology.

Visuospatial abilities and fine motor experiences influence acquisition and maintenance of fundamentals of laparoscopic surgery (FLS) task performance. Surg Endosc 2018; 32:4639-4648. [PMID: 29777356 DOI: 10.1007/s00464-018-6220-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2017] [Accepted: 05/09/2018] [Indexed: 10/16/2022]
Abstract
BACKGROUND Minimally invasive surgery poses a unique learning curve due to the requirement for non-intuitive psychomotor skills. The fundamentals of laparoscopic surgery (FLS) program trains and certifies residents in such skills. However, innate predictors of FLS performance and maintenance remain to be described. This single-centre observational study aimed to assess for candidate factors influencing the acquisition and maintenance of FLS performance amongst a surgically naïve cohort. METHODS Laparoscopically naïve medical students were recruited from pre-clinical university grades. Participants completed five visuospatial/psychomotor tests and a questionnaire surveying non-surgical experiences and personality traits. Individuals completed baseline assessments of FLS standard tasks followed by an intensive training course over week one and two on inanimate box trainers. A post-training assessment was performed in week three to evaluate acquisition. Participants were withdrawn from exposure and retested at four 1-month intervals to assess maintenance requirements. RESULTS Forty-nine participants enrolled with 35 (71.4%) and 33 (67.3%) completing acquisition and maintenance phases, respectively. Mean age of participants was 19.3 (± 1.2) years with 68.6% female predominance. Participants demonstrated significant improvements in all five tasks during the acquisition (p < 0.05) period and maintenance of skills with task exposure at 1-month intervals. Significant predictors of skill acquisition included: card rotations for intracorporeal knot (p = 0.027) and combined tasks (p = 0.028) and cube comparisons for extracorporeal knot (p = 0.040). During skill maintenance: Card rotations predicted performance across all tasks (p < 0.05), Cube comparisons for tasks 1/2/4/5 (p < 0.05), PicSOR for peg transfer (p = 0.017) and grooved pegboard for peg transfer (p = 0.023) and ligating-loop (p = 0.038) tasks. Musical instrument experience demonstrated associations with skill acquisition in peg transfer (p = 0.042) and intracorporeal knot (p = 0.034) while video gaming predicted performance in these tasks (p < 0.05) during the maintenance phase. A sporting background or competitive personality did not influence skill performance. CONCLUSIONS Multiple visuospatial abilities and non-surgical experiences positively influenced FLS performance during skill acquisition and/or maintenance. Further consideration to these individual factors may facilitate selection of more technically adaptable surgical residents.

Abstract
PURPOSE OF REVIEW The purpose of the review is to update the reader on the current literature and recent studies evaluating the role of simulation and warm-up as part of surgical education and training, and maintenance of surgical skills. RECENT FINDINGS Laparoscopic and hysteroscopic simulation may improve psychomotor skills, particularly for early-stage learners. However, data are mixed as to whether simulation education is directly transferable to surgical skill. Data are insufficient to determine if simulation can improve clinical outcomes. Similarly, performance of surgical warm-up exercises can improve performance of novice and expert surgeons in a simulated environment, but the extent to which this is transferable to intraoperative performance is unknown. Surgical coaching, however, can facilitate improvements in performance that are directly reflected in operative outcomes. SUMMARY Simulation-based curricula may be a useful adjunct to residency training, whereas warm-up and surgical coaching may allow for maintenance of skill throughout a surgeon's career. These experiences may represent a strategy for maintaining quality and value in a lower volume surgical setting.

Cost Comparison of Fundamentals of Laparoscopic Surgery Training Completed With Standard Fundamentals of Laparoscopic Surgery Equipment versus Low-Cost Equipment. JOURNAL OF SURGICAL EDUCATION 2017; 74:459-465. [PMID: 28011260 DOI: 10.1016/j.jsurg.2016.11.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Revised: 11/05/2016] [Accepted: 11/26/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE Training for the Fundamentals of Laparoscopic Surgery (FLS) skills test can be expensive. Previous work demonstrated that training on an ergonomically different, low-cost platform does not affect FLS skills test outcomes. This study compares the average training cost with standard FLS equipment and medical-grade consumables versus training on a lower cost platform with non-medical-grade consumables. DESIGN Subjects were prospectively randomized to either the standard FLS training platform (n = 19) with medical-grade consumables (S-FLS), or the low-cost platform (n = 20) with training-grade products (LC-FLS). Both groups trained to proficiency using previously established mastery learning standards on the 5 FLS tasks. The fixed and consumable cost differences were compared. SETTING Training occurred in a surgical simulation center. PARTICIPANTS Laparoscopic novice medical student and resident physician health care professionals who had not completed the national FLS proficiency curriculum and who had performed less than 10 laparoscopic cases. RESULTS The fixed cost of the platform was considerably higher in the S-FLS group (S-FLS, $3360; LC-FLS, $879), and the average consumable training cost was significantly higher for the S-FLS group (S-FLS, $1384.52; LC-FLS, $153.79; p < 0.001). The LC-FLS group had a statistically discernable cost reduction for each consumable (Gauze $9.24 vs. $0.39, p = 0.002; EndoLoop $540.00 vs. $40.60, p < 0.001; extracorporeal suture $216.45 vs. $25.20, p < 0.001; intracorporeal suture $618.83 vs. $87.60, p < 0.001). The annual fixed and consumable cost to train 5 residents is $10,282.60 in the S-FLS group versus $1647.95 in the LC-FLS group. CONCLUSIONS This study shows that the average cost to train a single trainee to proficiency using a lower fixed-cost platform and non-medical-grade equipment results in significant financial savings. A 5-resident program will save approximately $8500 annually. Residency programs should consider adopting this strategy to reduce the cost of FLS training.

Abstract
BACKGROUND The effects of refraining from practice for different intervals on laparoscopic suturing and mental workload was assessed with a secondary task developed by the authors. We expected the inability to practice to produce a decrease in performance on the suturing, knot tying, and secondary task and skills to rebound after a single refresher session. METHODS In total, 22 surgical assistant and premedical students trained to Fundamentals of Laparoscopic Surgery proficiency in intracorporeal suturing and knot tying were assessed on that task using a secondary task. Participants refrained from practicing any Fundamentals of Laparoscopic Surgery tasks for 1 or 5 months. At the time of their return, they were assessed immediately on suturing and knot tying with the secondary task, practiced suturing and knot tying for 40 minutes, and then were reassessed. RESULTS The mean suture times from the initial reassessment were greater than the proficiency times but returned to proficiency levels after one practice session, F(2, 40) = 14.5, P < .001, partial η2 = .420. Secondary task scores mirrored the results of suturing time, F(2, 40) = 6.128, P < .005, partial η2 = .235, and were moderated by retention interval. CONCLUSION When participants who reached proficiency in suturing and knot tying were reassessed after either 1or 5 months without practice, their performance times increased by 35% and secondary task scores decreased by 30%. These deficits, however, were nearly reversed after a single refresher session.

Abstract
OBJECTIVE Using previously established mastery learning standards, this study compares outcomes of training on standard FLS (FLS) equipment with training on an ergonomically different (ED-FLS), but more portable, lower cost platform. METHODS Subjects completed a pre-training FLS skills test on the standard platform and were then randomized to train on the FLS training platform (n = 20) or the ED-FLS platform (n = 19). A post-training FLS skills test was administered to both groups on the standard FLS platform. RESULTS Group performance on the pretest was similar. Fifty percent of FLS and 32 % of ED-FLS subjects completed the entire curriculum. 100 % of subjects completing the curriculum achieved passing scores on the post-training test. There was no statistically discernible difference in scores on the final FLS exam (FLS 93.4, ED-FLS 93.3, p = 0.98) or training sessions required to complete the curriculum (FLS 7.4, ED-FLS 9.8, p = 0.13). CONCLUSIONS These results show that when applying mastery learning theory to an ergonomically different platform, skill transfer occurs at a high level and prepares subjects to pass the standard FLS skills test.

Abstract
OBJECTIVES Currently, there is no standardized training protocol to teach surgeons how to deal with vascular injuries during laparoscopic procedures. The purpose of this study is to develop and evaluate the effectiveness of a standardized algorithm for managing vascular injury during laparoscopic nephrectomies. MATERIALS AND METHODS The performance of 6 surgeons was assessed during 10 laparoscopic nephrectomies in a porcine model. During the first and tenth operations, an injury was made in the renal vein without warning the surgeon. After the first procedure, the surgeons were instructed on how to proceed in dealing with the vascular injury, according to an algorithm developed by the designers of this study. The performance of each surgeon before and after learning the algorithm was assessed. RESULTS After learning the algorithm there was a decreased blood loss from 327 ± 403.11 ml to 37 ± 18.92 ml (p = 0.031) and decreased operative time from 43 ± 14.53 min to 27 ± 8.27 min (p = 0.015). There was also improvement in the time to start lesion repair from 147 ± 117.65 sec to 51 ± 39.09 sec (p = 0.025). There was a trend toward improvement in the reaction time to the injury (22 ± 21.55 sec vs. 14 ± 6.39, p = 0.188), the time required to control the bleeding (50 ± 94.2 sec vs. 14 ± 6.95 sec, p = 0.141), and the total time required to completely repair of the vascular injury (178 ± 170.4 sec vs. 119 ± 183.87 sec, p = 0.302). CONCLUSION A standardized algorithm may help to reduce the potential risks associated with laparoscopic surgery. Further studies will help to refine and determine the benefits of standardized protocols such as that developed in this study for the management of life-threatening laparoscopic complications.

Abstract
BACKGROUND We test a novel simulated teaching module's ability to educate junior residents in the assessment of compartment syndrome (CS) and compartment pressure measurement (CPM). METHODS Twenty-two postgraduate year 1 and postgraduate year 2 surgical residents received a 2-hour didactic and practical teaching module on CS assessment and CPM using a simulated model. A structured teaching session by a postgraduate year 5 surgical resident was assessed by carefully constructed pretest, post-test, and delayed retention tests and a practical testing session by 2 board-certified general surgeons. RESULTS Analysis of variance demonstrated significant difference between pretest (6.1/10), post-test (7.9/10), and retention test (8.2/10) scores [F (2,49) = 9.24, P < .01], with no difference in post-test to retention test comparison (P = .90). Mean CPM scores were 8.5/10 for preparation, 9.0/10 for performance, and 8.5/10 for management components, which did not differ [F (2,57) = .46, P = .63]. CONCLUSIONS We demonstrate an efficient simulated CS and CPM teaching module for the education of junior surgical residents using a synthetic model.

Abstract
The aim of this study was to assess whether mixed practice of basic tasks on a virtual reality (VR) simulator improves the performance of advanced tasks on the same device used for training as well as on a video trainer (VT). Thirty-six novices were allocated into 3 equal groups. Each group practiced on different combinations of basic tasks on a VR simulator: (A) peg transfer, (B) peg transfer and clipping, and (C) peg transfer, clipping, and cutting. Before and after training, each group performed a laparoscopic cholecystectomy (LC) scenario on the simulator and intracorporeal knot tying (KT) on a VT. Assessment metrics included time, instrument’s path length, penalty score, and hand motion synchronization. Results showed that for the common training tasks, plateau values were statistically equivalent for most assessment metrics ( P > .05). For LC, all groups showed significant performance improvement ( P < .05). For KT, group C improved significantly in pathlength ( P < .005), penalty score ( P < .05), and hand motion synchronization ( P < .05); the other groups failed to show an improvement ( P > .05). In conclusion, training on different VR tasks seems to have no effect on the performance of more demanding tasks on the same device. However, the number of different tasks practiced on the VR simulator seems to favorably affect the performance of advanced tasks on the VT.

Abstract
INTRODUCTION Laparoscopic tissue handling is quite difficult to measure using virtual-reality laparoscopic simulators and box-trainer exercises, and therefore, completion time is the predominant performance measure for simulation-based laparoscopic training exercises. The purpose of this study was to evaluate the construct validity of a training and assessment model for precise laparoscopic handling of delicate tissue. METHODS Participants (n = 35) completed 2 progressively challenging laparoscopic tissue translocation exercises using delicate foam pieces and templates. Deidentified performances were scored using objective measures for tissue damage, accuracy, percentage complete, and completion time. Evaluation included multiple analysis of variance with repeated measures among the 3 groups as follows: medical students, residents and faculty who perform laparoscopic surgery less than once per week, and faculty members who perform laparoscopic surgery at least once per week. RESULTS The model demonstrated significant construct validity by discriminating performances between the types of shapes and templates and across the levels of surgical experience on all dimensions. A significant interaction effect between the level of expertise and the difficulty of the exercise revealed excellent discrimination between experienced laparoscopic surgeons and others. DISCUSSION This low-cost model provides an alternative or adjunct platform for laparoscopic training and assessment that requires precise and measurable handling of a delicate tissue.

Abstract
AbstractBackgroundPatients having a course of radiotherapy (RT) must be appropriately immobilised for stability and accuracy. Having opened a new cancer service in June 2009 and commenced treating lower gastrointestinal cancers in 2010, a prone belly board device (BBD) was introduced as the standard radiotherapy immobilisation. A training package was created to aid clinical skills retention of therapeutic radiographers and manage setup quality. Setup reproducibility using the BBD was retrospectively assessed with electronic portal image (EPI) verified geometric displacements as the main outcome measure both before and after the introduction of training.MethodTwenty retrospective Pinnacle computed tomography-planned patients and their geometric displacements on treatment were evaluated between 2010 and 2011—ten prior to (Patient Group A) and ten following training (Patient Group B). The only inclusion criterion was that patients were immobilised for RT on the Medtec ContouraTM carbon fibre BBD. Patients were prone and were treated to 45–50·4 Gy in 25–28 fractions on a 6–10 MV LinAc equipped with EPI. Reproducibility was assessed by comparing geometric measurement of the bony pelvis on the Pinnacle digitally reconstructed radiograph (DRR) with an EPI captured at day 0, 1, 2 and weekly during treatment for each patient. Systematic and random errors were analysed with respect to the average geometric displacement with standard deviation per patient between the Pinnacle DRR and the EPI.ResultsThe age range was 41–77 years and there were 15 male and five female patients with diagnosed rectal cancers (T3–T4, N0–N2, M0). Three hundred and seventy one images were analysed. An improvement in population systematic and random error was most notable in the superior–inferior direction (Patient Group A Σpop = 3·1 mm, σpop = 3·6 mm to Patient Group B Σpop = 2·0 mm, σpop = 2·3 mm, respectively).Discussion/ConclusionThere is evidence that the use of the BBD is more reproducible when accompanied by a task-specific training package. Based on the results of this study, further work will be carried out on training standardisation for patient positioning with a BBD for reducing systematic and random geometric displacements.

Abstract
INTRODUCTION The clinical application of robotic surgery is increasing. The skills necessary to perform robotic surgery are unique from those required in open and laparoscopic surgery. A validated laparoscopic surgical skills curriculum (Fundamentals of Laparoscopic Surgery or FLS™) has transformed the way surgeons acquire laparoscopic skills. There is a need for a similar skills training and assessment tool for robotic surgery. Our research group previously developed and validated a robotic training curriculum in a virtual reality (VR) simulator. We hypothesized that novice robotic surgeons could achieve proficiency levels defined by more experienced robotic surgeons on the VR robotic curriculum, and that this would result in improved performance on the actual daVinci Surgical System™. METHODS 25 medical students with no prior robotic surgery experience were recruited. Prior to VR training, subjects performed 2 FLS tasks 3 times each (Peg Transfer, Intracorporeal Knot Tying) using the daVinci Surgical System™ docked to a video trainer box. Task performance for the FLS tasks was scored objectively. Subjects then practiced on the VR simulator (daVinci Skills Simulator) until proficiency levels on all 5 tasks were achieved before completing a post-training assessment of the 2 FLS tasks on the daVinci Surgical System™ in the video trainer box. RESULTS All subjects to complete the study (1 dropped out) reached proficiency levels on all VR tasks in an average of 71 (± 21.7) attempts, accumulating 164.3 (± 55.7) minutes of console training time. There was a significant improvement in performance on the robotic FLS tasks following completion of the VR training curriculum. CONCLUSIONS Novice robotic surgeons are able to attain proficiency levels on a VR simulator. This leads to improved performance in the daVinci surgical platform on simulated tasks. Training to proficiency on a VR robotic surgery simulator is an efficient and viable method for acquiring robotic surgical skills.

Abstract
INTRODUCTION Medical and surgical simulation is in high demand. It is widely used in North America as a method of education and training of medical students and surgical residents. Learning anatomy and vaginal surgery are based on palpation recognition of different structures. The absence of visual control of actions learners is a limiting factor for the reproducibility of surgical techniques prolapse and urinary incontinenence. However, this reproducibility is the only guarantee of success and safety of these minimally invasive surgeries. METHODS We evaluated the contribution of an educational module perineal anatomy using a system combining anatomic mannequin and a computerized 3D virtual simulator (Pelvic Mentor®, Simbionix) in the knowledge of pelvic-perineal anatomical structures for eight residents of obstetrics and gynecology hospitals in Paris. RESULTS The self-study training module has led to substantial improvements in internal rating with a proportion of structures recognized from 31.25 to 87.5 % (P<0.001) for the front compartment and 20 to 85 % (P<0.001) for the posterior compartment. CONCLUSION The preliminary results suggest that the 3D virtual simulator enhances and facilitates learning the anatomy of the pelvic floor.

Abstract
OBJECTIVE To investigate whether preclinical laparoscopy training offers a benefit over standard apprenticeship training and apprenticeship training in combination with simulation training. DESIGN This randomized controlled trial consisted of 3 groups of first-year surgical registrars receiving a different teaching method in laparoscopic surgery. SETTING The KU LEUVEN Faculty of Medicine is the largest medical faculty in Belgium. PARTICIPANTS Thirty final-year medical students starting a general surgical career in the next academic year. METHODS Thirty final-year medical students were randomized into 3 groups, which differed in the way they were exposed to laparoscopic simulation training but were comparable in regard to ambidexterity, sex, age, and laparoscopic psychomotoric skills. The control group received only clinical training during surgical residentship, whereas the interval group received clinical training in combination with simulation training. The registrars were allowed to do deliberate practice. The Centre for Surgical Technologies Preclinical Training Programme (CST PTP) group received a preclinical simulation course during the final year as medical students, but was not exposed to any extra simulation training during surgical residentship. At the beginning of surgical residentship and 6 months later, all subjects performed a standardized suturing task and a laparoscopic cholecystectomy in a POP Trainer. All procedures were recorded together with time and motion tracking parameters. All videos were scored by a blinded observer using global rating scales. RESULTS At baseline the 3 groups were comparable. At 6 months, for suturing, the CST PTP group was better than both the other groups with respect to time, checklist, and amount of movements. The interval group was better than the control group on only the time and checklist score. For the cholecystectomy evaluation, there was a statistical difference between the CST PTP study group and both other groups on all evaluation scales in favor of the CST PTP group. CONCLUSIONS Structured, preclinical proficiency-based training is better than clinical training combined with laboratory training or clinical training alone.

Abstract
Introduction Surgical education has become one of the most important directions in modern surgery evolution. To meet growing need for appropriate training in laparoscopic and, even more importantly, classic surgical skills, a curriculum involving contemporary tuition methods is needed. Advanced, structuralised training, which includes advanced technologies like virtual reality training, video coaching and motivative aspects of competition, seems to be important for an adequate education programme. Material and methods In academic years 2009/2010 and 2010/2011 the Department of General, Endocrine and Transplant Surgery of the Medical University of Gdansk together with the Pomeranian Foundation for Progress in Surgery organized 4480 h of training in that area of classic (2744) and laparoscopic (1736) skills. Both groups were involved in the programme of training in which the two most important aspects were reliable evaluation of the results and effective motivation to work. Skill evaluation at different stages of the programme were based on completion time and quality measurements. Apart from that, at the end of the course, the participants completed a questionnaire on their subjective perspective on this innovative curriculum, the quality and stability of the skills they obtained. Results In both arms of the programme (laparoscopic and classic) a statistically significant improvement was obtained as early as after the second and third sessions in half of the exercises. The acquired skills were stable over time, as proved by the plateau of completion time achieved in 11 out of 12 exercises. The results of the post-training questionnaire revealed that the participants were very satisfied with the structuralised form of training and appreciated the motivational role of competition. Conclusions Contemporary surgical training should be organized as a systematic, well-evaluated and goal-oriented programme similar to the one proposed by our team. The use of contemporary training aids should be utilized in training of every surgical skill, not only laparoscopy. This form of training, associated with the component of competition, enables good and stable results to be achieved, as well as high satisfaction of trainees.

Factors Influencing Radiation Therapists' Perceptions of Performing Manual Monitor Unit Calculations in a Computer-Based Work Environment. J Med Imaging Radiat Sci 2013; 44:31-36. [PMID: 31052045 DOI: 10.1016/j.jmir.2012.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2012] [Revised: 09/03/2012] [Accepted: 09/06/2012] [Indexed: 11/22/2022]
Abstract
INTRODUCTION Despite increased automation in the field of radiation therapy, the need to perform monitor unit calculations manually still exists for a small number of clinical situations. Challenges in maintaining the skill of performing infrequently occurring clinical tasks have been identified among other health professions, but no study has been performed for similar issues in radiation therapy. The aim of this study was to explore radiation therapists' (RT) perceived changes in comfort level to perform manual calculations (MC), an infrequently occurring clinical task, and to evaluate factors that may have influenced the change in comfort level. METHODS AND MATERIALS The study sample consisted of RTs working within the radiation therapy department of a cancer hospital. A questionnaire soliticing RTs' comfort level with MC and potential influencing factors was sent to each participant. The difference in responses based on key study variables, including initial mastery of MC, ongoing exposure to MC, recent exposure to MC, and MC continuing education, was analyzed. In addition, a wave analysis was performed to determine whether the responses gathered with the questionnaire were representative of those who did not respond. RESULTS Fifty-one responses were obtained. The wave analysis suggested that our study results may reflect the views of those of RTs who were eligible to participate, but did not respond. Ninety percent of the participants reported that their comfort level in performing MC had decreased over the years. A significantly smaller proportion of participants reported being comfortable with orthovoltage MC (14%) compared to other types of MC (75-84%). Participants' years of work experience did not appear to influence their comfort level in performing MC. A higher proportion of participants that had recent or ongoing exposure to MC, including those that performed a MC within the last 12 months, worked in dosimetry, were engaged in on-call activities, or were engaged in continuing education on MC, reported being more comfortable in MC than those participants who did not engage in such activities (91%-92% vs. 47%-71%, P < .001). DISCUSSION/CONCLUSION Initial mastery and ongoing exposure were identified in the literature as important factors that influence practitioners' ability in performing clinical tasks. Although initial mastery was found to influence comfort level in performing MC, our study also revealed that ongoing exposure may be relatively more important. Lessons drawn from this study will become more important to the field of radiation therapy as more manually performed clinical tasks become less frequent over time. To address potential reduction in RTs' ability in performing this infrequent clinical task, individual radiotherapy departments have historically put in place effective strategies to assure accuracy. Yet, alternatives to performing MC should be explored in order to maximize safety, efficiency, and quality of patient care.

Abstract
BACKGROUND The purpose of this study was to develop an intermediate-level proficiency-based knot-tying and suturing curriculum, evaluate construct validity, determine feasibility, document educational benefit, and quantify cost-effectiveness of implementation within a surgery residency program. METHODS Six tasks with standardized metrics were developed using commercially available bench models; 39 PGY-1 surgery residents were enrolled in a 2-month curriculum (orientation/pre-test, self-practice, and a proctored post-test). Baseline trainee and expert performance were compared to assess construct validity. RESULTS Baseline trainee and expert performance were significantly different (451 ± 83 vs 644 ± 10, p < 0.001), supporting construct validity. All trainees achieved proficiency during self-practice, completing 30 ± 17 repetitions over 3.4 ± 3.8 hours. Significant differences were detected between baseline and final trainee composite scores (451 ± 83 vs 607 ± 34, p < 0.001). CONCLUSIONS Implementation of this curriculum was feasible and cost-effective. Construct validity and educational benefit in terms of skill acquisition were demonstrated. The purpose of this study was to develop an intermediate-level proficiency-based knot-tying and suturing curriculum, evaluate construct validity, determine feasibility, document educational benefit, and quantify cost-effectiveness of implementation within a robust surgery residency training program.

Abstract
It is now clear to most stakeholders that acquisition of surgical psychomotor skills is best achieved outside of the clinical operating room, in the context of a simulated environment. Endoscopic simulation can be accomplished using simple "box" simulators or video trainers, and virtual reality simulation is now possible using microprocessor-controlled systems. Structured surgical training performed outside of the operating room environment is relatively new to health care, a circumstance different from the process of pilot training, in which simulation has been a mainstay for more than 75 years and in which virtual reality simulation is now the norm. Those charged with surgical education are faced with a dilemma as, while attempting to understand the basic goals of simulation, they are simultaneously faced with choice between relatively inexpensive video trainers and the often prohibitively expensive virtual reality systems. This article explores the history of simulation, reports the results of a modified systematic review of currently available systems and performance, and identifies the gaps in current research and development. It is apparent that available video trainers provide the opportunity for skill development that at present is not surpassed by virtual reality systems. In the future, there will likely be an increasing role for virtual reality; however, challenges remain that include determination of the appropriate metrics and system design, and the fiscal resources necessary for the required hardware and related software development.

Abstract
BACKGROUND AND AIM Structured training on box trainers in laparoscopic skills in the initial years of residency has been used and found to be effective. Although there are studies that confirm immediate improvement after training, there is a lack of well-designed trials addressing the crucial issue of retention of these skills over time. The purpose of this study is to assess improvement in laparoscopic skills of surgical trainees after structured training on box trainers, compared with traditional training (observing and assisting laparoscopic procedures in the operation rooms) immediately and after 5 months. METHODS Forty surgical residents in their first 2 months of residency training were randomized to either structured training on box trainers, in addition to traditional training, or to traditional training alone. Groups were equivalent with regards to demographics, previous operative experience, and baseline skills. Structured training consisted of 4 sessions with 6 tasks on box trainers under supervision and self practice. Task-based objective structured practical examinations (OSPE) were completed before and after each task. At the end of the training, residents were assessed by a blinded faculty member with the global operative assessment of laparoscopic skills (GOALS) rating scale. Residents also completed a satisfaction questionnaire. Focus group discussions were conducted for both groups. The GOALS were repeated for both the groups at the end of 5 months to assess retention of skills. RESULTS The mean GOALS score was significantly higher for the structured training group (mean/SD 20.35 + 0.74) compared with the traditional training group (mean/SD 16.35 + 1.75, p < 0.01) at the end of 5 months. The mean global rating scale (GRS) score was significantly higher (Pre 7.55 + 0.99 vs. Post 16.4 + 0.68, p < 0.01) for the structured training group at the end of course. Residents in the structured training group had significantly improved skills immediately after the training and had better retention of skills at the end of five months. CONCLUSIONS Structured training on box trainers, in addition to traditional training, compared with traditional training alone, leads to better skills and improved confidence of residents. There is significant retention of skills at the end of 5 months. These results provide support for incorporation of structured training with box trainers for laparoscopic skills into surgical training programs.

Abstract
BACKGROUND We previously developed nine inanimate training exercises as part of a comprehensive, proficiency-based robotic training curriculum that addressed 23 unique skills identified via task deconstruction of robotic operations. The purpose of this study was to evaluate construct validity, workload, and expert levels for the nine exercises. METHODS Expert robotic surgeons (n = 8, fellows and faculty) and novice trainees (n = 4, medical students) each performed three to five consecutive repetitions of nine previously reported exercises (five FLS models with or without modifications and four custom-made models). Each task was scored for time and accuracy using modified FLS metrics; task scores were normalized to a previously established (preliminary) proficiency level and a composite score equaled the sum of the nine normalized task scores. Questionnaires were administered regarding prior experience. After each exercise, participants completed a validated NASA-TLX Workload Scale to rate the mental, physical, temporal, performance, effort, and frustration levels of each task. RESULTS Experts had performed 119 (range = 15-600) robotic operations; novices had observed ≤ 1 robotic operation. For all nine tasks and the composite score, experts achieved significantly better performance than novices (932 ± 67 vs. 618 ± 111, respectively; P < 0.001). No significant differences in workload between experts and novices were detected (32.9 ± 3.5 vs. 32.0 ± 9.1, respectively; n.s.). Importantly, frustration ratings were relatively low for both groups (4.0 ± 0.7 vs. 3.8 ± 1.6, n.s.). The mean performance of the eight experts was deemed suitable as a revised proficiency level for each task. CONCLUSION Using objective performance metrics, all nine exercises demonstrated construct validity. Workload was similar between experts and novices and frustration was low for both groups. These data suggest that the nine structured exercises are suitable for proficiency-based robotic training.

MATERIALS AND METHODS Eighty-seven surgical postgraduate students participated in this study, including novice (N), junior (JR), and senior (SR) trainees. The N trainees were divided into novice control (NC) and novice experimental (NE) groups. The training curricula contain three stages: Fundamentals of laparoscopic surgery tasks, intensive laparoscopic suturing task, and laparoscopic enucleation model training. The NE, JR, and SR groups completed all three stages. The NC group just performed the first and third stages. The performances of each group were recorded and analyzed. RESULTS For the first stage, the SR group performed better than the N and JR groups. There was no significant difference in the post-test total scores between the N and JR groups, although the N group had lower pretest total scores. For the second stage, no significant difference was found in the post-test scores among the NE, JR, and SR groups, although the SR group had better pretest scores. For the third stage, the NE, JR, and SR groups had better performance than the NC group at the five exercises. There was no significant difference at the fifth exercise among the NE, JR, and SR groups, although the SR group performed better at the former four exercises. CONCLUSION This study documented the feasibility of intensive laparoscopic training curricula shortening the learning curve of laparoscopic suturing in surgical postgraduate students, regardless of baseline experience.

Abstract
INTRODUCTION Surgical training relies on medical school lectures, practical training in patient care and in the operating room including instruction in anatomy and experimental surgery. Training with different techniques of simulators can complete this. Simulator-based training, widely used in North America, can be applied to several aspects of surgical training without any risk for patients: technical skills in both open and laparoscopic surgery, the notion of teamwork and the multidisciplinary management of acute medicosurgical situations. METHOD We present the curriculum developed in the Simulation Center of the Medical School of Nice Sophia-Antipolis. All residents in training at the Medical School participate in this curriculum. RESULTS Each medical student is required to pursue theoretical training (familiarization with the operating room check-list), training in patient management using a high fidelity mannequin for various medical and surgical scenarios and training in technical gestures in open and laparoscopic surgery over a 2-year period, followed by an examination to validate all technical aptitudes. This curriculum has been approved and accredited by the prestigious American College of Surgeons, making this the first of its kind in France. CONCLUSION As such, it should be considered as a model and, in accordance to the wishes of the French Surgical Academy, the first step toward the creation of true schools of surgery.

Abstract
BACKGROUND In laparoscopic surgery, the role of camera holder often falls to untrained medical students. Laparoscopic-naive students can easily acquire laparoscopic camera navigation (LCN) skills, yet it is unclear whether this translates into improved LCN performance in the operating room and whether students retain these skills over time. The purpose of this study was to evaluate whether preclinical laparoscopic camera simulator training would result in improved LCN skills, efficiency, and comfort level over the course of a 6-week surgery clerkship. METHODS A randomized, controlled study was designed to compare students' preclerkship and postclerkship LCN skills on a previously validated box trainer model. The students (n = 70) were randomized via a computer-generated table of random numbers into study and control groups. The study group (n = 36) received a brief laparoscope training session before the clerkship, while the control group (n = 36) did not. All students also completed a preclerkship and postclerkship questionnaire detailing their experience and comfort level. RESULTS Statistical analysis using Wilcoxon's signed-rank test demonstrated that all students improved in skill level (total score, 4 vs 7; P < .0001), efficiency (time, 76 vs 33 seconds; P < .0001), and comfort level (Likert scale score, 2 vs 4; P < .0001), with no statistically significant difference between the control and study groups. CONCLUSIONS This study demonstrates that novice medical students are able to gain laparoscopic camera skills from "hands-on" experience, with no added benefit or retention of skills learned in a preclinical camera simulator training session.

Abstract
PURPOSE In 2006, The Japanese Society of Pediatric Endoscopic Surgeons devised a plan to develop a pediatric endoscopic surgical skill qualification (ESSQ) system. This system is controlled by The Japan Society for Endoscopic Surgery. The standard requirement for skills qualification is the ability of each applicant to complete common types of laparoscopic surgery. The main goal of the system is to decrease complications of laparoscopic surgery by evaluating the surgical skills of each applicant and subsequently certify surgeons with adequate skills to perform laparoscopic operations safely. METHODS A committee of pediatric ESSQ created a checklist to assess the applicant's laparoscopic surgical skills. Skills are assessed in a double-blinded fashion by evaluating an unedited video recording of a fundoplication for pediatric gastroesophageal reflux disease. RESULTS The initial pediatric ESSQ system was started in 2008. In 2008 and 2009, respectively, 9 out of 17 (53%) and 6 out of 12 (50%) applicants were certified as expert pediatric laparoscopic surgeons. CONCLUSIONS Our ultimate goal is to provide safe and appropriate pediatric minimally invasive procedures and to avoid severe complications. To prove the predictive validity of this system, a survey of the outcomes of operations performed by certified pediatric surgeons is required.
