Abstract
INTRODUCTION Limitations to surgical education access were exacerbated during the COVID-19 Pandemic. In response, we created a national home-based comprehensive surgical skills course: Monash Online Surgical Training (MOST). Our aim was to evaluate the educational impact of this approach. METHODS A remote, 6-week course was designed with learning objectives aligned to the national surgical training. Participants received a personal laparoscopic bench trainer, instrument tracking software, live webinars, access to an online theoretical learning platform, and individualised feedback by system-generated or expert surgeons' assessments. Mixed method analysis of instrument tracking metrics, pre- and post-course questionnaires (11 core surgical domains) and participant comments was utilised. Data were analysed using the Mann-Whitney U test, and a p-value of < 0.05 was considered statistically significant. RESULTS A total of 54 participants with varied levels of experience (1 to > 6 years post-graduate level) completed MOST. All 11 learning-outcome domains demonstrated statistically significant improvement including core laparoscopic skills (1.4/5 vs 2.8/5, p < 0.0001) and handling laparoscopic instruments (1.5/5 vs 2.8/5, p < 0.0001). A total of 3460 tasks were completed reflecting 158.2 h (9492 min) of practice, 394 were submitted for formal feedback. Participants rated the course (mean 8.5/10, SD 1.6), live webinars (mean 8.9/10, SD 1.6) and instrument tracking software (mean 8.6, SD 1.7) highly. Qualitative analysis revealed a paradigm shift including the benefits of a safe learning environment and self-paced, self-directed learning. CONCLUSION The MOST course demonstrates the successful implementation of a fully remote laparoscopic simulation course which participants found to be an effective tool to acquire core surgical skills.

Abstract
INTRODUCTION There is a critical need for comprehensive surgical training in African countries given the unmet surgical burden of disease in this region. Collaborative and progressive initiatives in global surgical education will have the greatest impact on trainees. Little is known about surgical education needs from the perspective of practicing surgeons and trainees in low-middle-income countries (LMICs). Even less is known about the potential role for simulation to augment training. METHODS A modified Delphi methodology with 2 rounds of responses was employed to survey program directors (PD) and associate program directors (APD) of Pan-African Association of Christian Surgeons (PAACS) general surgery residency programs across eight low-middle-income countries in Africa. 3 PD/APDs and 2 surgical residents participated in semi-structured interviews centered around the role of simulation in training. Descriptive analysis was performed to elicit key themes and illustrative examples. RESULTS The survey of program directors revealed that teaching residents the psychomotor skills need to perform intracorporeal suturing was both high priority and desired in multiple training sites. Other high priority skills were laparoscopic camera driving and medial visceral rotation. The interviews revealed a specific desire to perform laparoscopic surgery and a need for a simulation curriculum to familiarize staff and trainees with laparoscopic techniques. Several barriers to laparoscopic surgery exist, such as lack of staff familiarity with the equipment, lack of public buy in, and lack of generalizable and adaptable educational modules. Trainees saw utility in the use of simulation to optimize time in the operating room and sought opportunities to improve their laparoscopic skills. CONCLUSION Faculty and surgical trainees in LMICs have interest in learning advanced surgical techniques, such as laparoscopy. Developing a simulation curriculum tailored to the trainees' local context has the potential to fill this need.

Abstract
Introduction: Minimally invasive surgery (MIS) suturing demands advanced surgical skills. Therefore, it is important these skills are adequately trained and assessed. Assessment and feedback can consist of judgments and scores of expert observers or objective parameters using instrument tracking. The aim of this study was to determine to what extent objective parameters correspond to expert assessment. Methods: Participants performed an intracorporeal suturing task on the EoSim simulator repeatedly (maximum 20 repetitions) during training. The best discriminating parameters, which previously shown construct validation, were combined into a composite score, using regression analysis. All videos were blinded and assessed by 2 independent reviewers using the validated laparoscopic suturing competency assessment tool (LS-CAT). These scores were compared with the composite score. Results: A 100 videos of 16 trainees, during separate points on their learning curve, and 8 experts were used. The parameters "time" and "distance" were statistically significantly correlated with all LS-CAT domains. The composite score (calculated from "time" and "distance") showed improvement between the first and the last knot (57% versus 94%, P < .001). Also the LS-CAT score improved (28 versus 17, P < .001). However, the correlation of the composite score with the LS-CAT score was weak (R: 0.351), with an accuracy of 55/100 when pooling the outcomes based on inadequate, adequate, or good performance. Conclusion: Instrument tracking parameters (using Surgtrac) could give an indication of the skill level, however, it missed important elements, essential for reliable assessment. Therefore, expert assessment remains superior to determine the skill level in MIS suturing skills.

Abstract
Objective: While instructional videos are commonly used in surgical education, there is a paucity of data on home laparoscopic box trainers. This pilot study evaluated impacts of augmenting instructional videos with these devices. Design: This was a randomized controlled pilot study evaluating laparoscopic surgical performance on the LapSim virtual surgical simulator before and after a 2 week curriculum of instructional videos alone (n = 8, 47.1%) vs videos plus a home laparoscopic box trainer (n = 9, 52.9%). The LapSim recorded mistake number, time, and instrument path length to complete each task. Participants completed surveys about their perceptions of surgery before and after the course. Participants: Preclinical medical students were recruited. Those with extensive surgical experience or did not complete the course were excluded. Results: For the box trainer group vs the videos alone group: mean change in mistakes was -10.0 (standard deviation [SD]:17.1) vs +.5 (SD:21.59) (P = .28); mean change in time was -433.24 (SD:304.67) seconds vs -366.16 (SD:240.10) seconds (P = .62); mean change in instrument path length was -4.27 (SD:4.38) meters vs -3.19 (SD:4.86) meters (P = .64). The box trainer group ranked "I feel as though surgery comes naturally" 1.58 points higher (95% confidence interval [CI]: .85, 2.32; P < .01) and "I am worried about being skilled at surgery" 1.26 points lower (95% CI: 2.29, -.24; P = .02) upon completing the study. The videos alone group reported no significant changes in survey responses. Conclusion: Home laparoscopic box trainers can generate confidence and reduce anxiety regarding surgical fields. This study provides a framework for future larger scale works.

Optimizing laparoscopic training efficacy by 'deconstruction into key steps': a randomized controlled trial with novice medical students. Surg Endosc 2022; 36:8726-8736. [PMID: 35851816 PMCID: PMC9652220 DOI: 10.1007/s00464-022-09408-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 06/19/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND Simulator training is an effective way of acquiring laparoscopic skills but there remains a need to optimize teaching methods to accelerate learning. We evaluated the effect of the mental exercise 'deconstruction into key steps' (DIKS) on the time required to acquire laparoscopic skills. METHODS A randomized controlled trial with undergraduate medical students was implemented into a structured curricular laparoscopic training course. The intervention group (IG) was trained using the DIKS approach, while the control group (CG) underwent the standard course. Laparoscopic performance of all participants was video-recorded at baseline (t0), after the first session (t1) and after the second session (t2) nine days later. Two double-blinded raters assessed the videos. The Impact of potential covariates on performance (gender, age, prior laparoscopic experience, self-assessed motivation and self-assessed dexterity) was evaluated with a self-report questionnaire. RESULTS Both the IG (n = 58) and the CG (n = 68) improved their performance after each training session (p < 0.001) but with notable differences between sessions. Whereas the CG significantly improved their performance from t0 -t1 (p < 0.05), DIKS shortened practical exercise time by 58% so that the IG outperformed the CG from t1 -t2, (p < 0.05). High self-assessed motivation and dexterity associated with significantly better performance (p < 0.05). Male participants demonstrated significantly higher overall performance (p < 0.05). CONCLUSION Mental exercises like DIKS can improve laparoscopic performance and shorten practice times. Given the limited exposure of surgical residents to simulator training, implementation of mental exercises like DIKS is highly recommended. Gender, self-assessed dexterity, and motivation all appreciably influence performance in laparoscopic training.

Abstract
BACKGROUND An international surgical team implemented a virtual basic laparoscopic surgery course for Bolivian general and pediatric surgeons and residents during the COVID-19 pandemic. This simulation course aimed to enhance training in a lower-resource environment despite the challenges of decreased operative volume and lack of in-person instruction. METHODS The course was developed by surgeons from Bolivian and U.S.-based institutions and offered twice between July-December 2020. Didactic content and skill techniques were taught via weekly live videoconferences. Additional mentorship was provided through small group sessions. Participants were evaluated by pre- and post-course tests of didactic content as well as by video task review. RESULTS Of the 24 enrolled participants, 13 were practicing surgeons and 10 were surgery residents (one unspecified). Fifty percent (n = 12) indicated "almost never" performing laparoscopic surgeries pre-course. Confidence significantly increased for five laparoscopic tasks. Test scores also increased significantly (68.2% ± 12.5%, n = 21; vs 76.6% ± 12.6%, n = 19; p = 0.040). While challenges impeded objective evaluation for the first course iteration, adjustments permitted video scoring in the second iteration. This group demonstrated significant improvements in precision cutting (11.6% ± 16.7%, n = 9; vs 62.5% ± 18.6%, n = 6; p < 0.001), intracorporeal knot tying (36.4% ± 38.1%, n = 9; vs 79.2% ± 17.2%, n = 7; p = 0.012), and combined skill (40.3% ± 17.7%; n = 8 vs 77.2% ± 13.6%, n = 4; p = 0.042). Collectively, combined skill scores improved by 66.3% ± 10.4%. CONCLUSION Virtual international collaboration can improve confidence, knowledge, and basic laparoscopic skills, even in resource-limited settings during a global pandemic. Future efforts should focus on standardizing resources for participants and enhancing access to live feedback resources between classes.

Abstract
BACKGROUND Pediatric surgeons require highly advanced minimally invasive surgical skills to perform rare and complex surgeries in a very vulnerable population. We developed a neonatal esophageal atresia (EA) model to improve thoracoscopic surgical skills. This study aimed to evaluate the concurrent validity of the model by undertaking pre- and post-training skills assessments in two groups of students with no prior experience performing minimally invasive surgery, using the EA model and a dry box (DB). METHODS A pilot study was performed. The participants were randomly divided into two groups: one trained using the DB and one trained using the EA model. Both groups practiced a minimally invasive surgical suture task. The task completion time, 29-point checklist score, modified suturing error sheet score, and three-dimensional forceps movement in both groups were compared pre-and post-training by video analysis. RESULTS The EA model task was significantly more difficult than that of the DB. Both groups showed significant improvement in the task time, 29-point checklist score, and modified suturing error sheet score; however, the EA model training was more efficient in improving each error item. Regarding forceps movement, the EA model training significantly decreased wasted motion, whereas the DB was limited in this regard. CONCLUSIONS Short-term training on the EA model, which was more technically demanding than the DB, decreased technical error and wasted motion, and allowed learners to acquire surgical skills more efficiently than training with the DB model. These facts revealed the concurrent validity of the EA model.

Abstract
Context: The aim was to identify the current training standard of laparoscopy skills among the urology residents. Aims: This paper presents the residents’ subjective perception of their laparoscopy skills and evidence of an objective assessment of their actual skills. Settings and Design: An online survey was mailed, and completed by urology residents in training. The residents’ perception of laparoscopy training received, exposure to laparoscopy procedures, and training facilities were queried. The assessment was done on the skill levels of the residents presenting at an annual training program. Subjects and Methods: 103 residents responded to the online survey and 115 residents were assessed at the training program. Statistical Analysis Used: Discrete data were compared using the t-test to test for significance of the means; P < 0.05 was considered significant. Pearson's correlation coefficient was used to obtain the relationship between variables. Results: An overwhelming 91% rated their laparoscopy skill as just “satisfactory” or worse, and 60% did not have any training facilities in their department. 66% continue to be “assistants only” in conventional laparoscopy surgeries. Assessment of basic laparoscopy skills in the dry lab revealed 92% of residents having poor laparoscopy skills; similar to the subjective opinion in the survey. Only 6% (n = 5) of the residents showed a good or better skill score in the dry lab; similar to the survey. Conclusions: Based on the survey, a large number of residents have a poor opinion of their own laparoscopy skills, and the training facilities available to them. The data objectively prove the self-assessment of the residents on their laparoscopy skill level.

Abstract
BACKGROUND Elucidating how robotic skills are best obtained will enable surgeons to best develop future robotic training programs. We perform a randomized controlled trial to assess the performance of robotic compared to laparoscopic surgery, transference of pre-existing skills between the two modalities, and to assess the learning curve between the two using novice medical students. METHODS Forty students were randomized into either Group A or B. Students practiced and were tested on a peg transfer task in either a laparoscopic simulator (LS) and robotic simulator (RS) in a pre-defined order. Performance, transference of skills and learning curve were assessed for each modality. Additionally, a fatigue questionnaire was issued. RESULTS There was no significant difference between overall laparoscopic scores (219 ± 19) and robotic scores (227 ± 23) (p = 0.065). Prior laparoscopic skills performed significantly better on robotic testing (236 ± 12) than without laparoscopic skills (216 ± 28) (p = 0.008). There was no significant difference in scores between students with prior robotic skills (223 ± 16) than without robotic skills (215 ± 22) (p = 0.162). Students reported no difference in fatigue between RS and LS. The learning curve plateaus at similar times between both modalities. CONCLUSION Novice medical students with laparoscopic skills performed better on a RS test than students without laparoscopic training, suggesting a transference of skills from laparoscopic to robotic surgery. These results suggest laparoscopic training may be sufficient in general surgery residencies as the skills transfer to robotic if used post-residency.

Abstract
BACKGROUND Despite the acknowledgement of human factors, application of psychological methods by surgeons to improve surgical performance is sparse. This may reflect the paucity of evidence that would help surgeons to use psychological techniques effectively. There is a need for novel approaches to see how cognitive training might be used to address these challenges. METHODS Surgical trainees were divided into intervention and control groups. The intervention group received training in surgical cognitive simulation (SCS) and was asked to apply the techniques while working in operating theatres. Both groups underwent procedure-based assessment based on the UK and Ireland Intercollegiate Surgical Curriculum Programme (ISCP) before the training and 4 months afterwards. Subjective evaluations of SCS application were obtained from the intervention group participants. RESULTS Among 21 participants in the study, there was a statistically significant improvement in 11 of 16 procedure-based assessment domains (P < 0.050) as well as a statistically significant mean reduction in time to complete the procedure in the intervention group (-15.98 versus -1.14 min; P = 0.024). Subjectively, the intervention group experienced various benefits with SCS, especially in preoperative preparedness, intraoperative focus, and overall performance. CONCLUSION SCS training has a statistically significant impact in improving surgical performance. Subjective feedback suggests that surgeons are able to apply it in practice. SCS may prove a vital adjunct for skill acquisition in surgical training.

Abstract
Introduction Music can have a positive effect on stress and general task performance. This randomized crossover study assessed the effects of preferred music on laparoscopic surgical performance in a simulated setting. Methods Sixty medical students, inexperienced in laparoscopy, were included between June 2018 and November 2018. A randomized, 4-period, 4-sequence, 2-treatment crossover study design was used, with each participant acting as its own control. Participants performed four periods, consisting of five peg transfer tasks each period, on a laparoscopic box trainer: two periods while wearing active noise-cancelling headphones and two periods during music exposure. Participants were randomly allocated to a sequence determining the order of the four periods. The parameters time to task completion, path length and normalized jerk were assessed. Mental workload was assessed using the Surgical Task Load Index questionnaire. Also, heart rate and blood pressure were assessed. Results Participants performed the peg transfer task significantly faster [median difference: − 0.81 s (interquartile range, − 3.44–0.69) p = 0.037] and handled their instruments significantly more efficient as path length was reduced [median difference, − 52.24 mm (interquartile range, − 196.97–89.81) p = 0.019] when exposed to music. Also, mental workload was significantly reduced during music [median difference, − 2.41 (interquartile range, − 7.17–1.83) p = 0.021)]. No statistically significant effect was observed on heart rate and blood pressure. Conclusion Listening to preferred music improves laparoscopic surgical performance and reduces mental workload in a simulated setting. Trial registration Trial registration number: NCT04111679.

Management of Bleeding Complications in Virtual Reality Laparoscopy. Int Surg 2020.

Abstract
The aim of this study was to compare the impact of induced bleeding complication training with regular training on a virtual reality laparoscopic (VRL) simulator. Although bleeding complications occur rarely during laparoscopic surgery, they usually arise without warning and may have severe consequences for the patient because complication management training is not currently widespread. Third-year medical students (n = 41) were randomly selected for 2 curricular courses on how to perform a bimanual task on a VRL simulator. Both the regular training group (RTG) and the induced bleeding complication training (ICT) group performed 2 regular training sessions and 9 training sessions. For the ICT group the training sessions were with a bleeding complication. The 2 groups were comparable regarding their initial performance levels and improved significantly in task time and handling economics throughout the course (P < 0.001). When a bleeding complication occurred during the initial phase, performance parameters were significantly worse (P < 0.05). During a bleeding complication, the ICT group showed a significant improvement in time, handling economics, and blood loss (P < 0.001) throughout the training course, whereas the RTG group showed no improvement. Induced complication training has a positive influence on the management of bleeding on the VRL simulator. Structured laparoscopic complication management training should be implemented during surgical education as an add-on to regular procedural training.

Abstract
Colorectal surgery has been revolutionised towards minimally invasive surgery with the emergence of enhanced recovery protocol after surgery initiatives. However, laparoscopic colectomy has yet to be widely adopted, due mainly to the steep learning curve. We aim to review and discuss the methods of overcoming these learning curves by accelerating the competency level of the trainees without compromising patient safety. To provide this mini review, we assessed 70 articles in PubMed that were found through a search comprised the keywords laparoscopic colectomy, minimal invasive colectomy, learning curve and surgical education. We found England's Laparoscopic Colorectal National Training Programme (LAPCO-NTP) England to be by far the most structured programme established for colorectal surgeons, which involves pre-clinical and clinical phases that end with an assessment. For budding colorectal trainees, learning may be accelerated by simulator-based training to achieve laparoscopic dexterity coupled with an in-theatre proctorship by field experts. Task-specific checklists and video recordings are essential adjuncts to gauge progress and performance. As competency is established, careful case selections with the proctor are essential to maintain motivation and ensure safe performances. A structured programme to establish competency is vital to help both the proctor and trainee gauge real-time progress and performance. However, training systems both inside and outside the operating theatre (OT) are equally useful to achieve the desired performance.

Abstract
Background The high cost and low availability of virtual reality simulators in surgical specialty training programs in low- and middle-income countries make it necessary to develop and obtain sources of validity for new models of low-cost portable simulators that enable ubiquitous learning of psychomotor skills in minimally invasive surgery. Objective The aim of this study was to obtain validity evidence for relationships to other variables, internal structure, and consequences of testing for the task scores of a new low-cost portable simulator mediated by gestures for learning basic psychomotor skills in minimally invasive surgery. This new simulator is called SIMISGEST-VR (Simulator of Minimally Invasive Surgery mediated by Gestures - Virtual Reality). Methods In this prospective observational validity study, the authors looked for multiple sources of evidence (known group construct validity, prior videogaming experience, internal structure, test-retest reliability, and consequences of testing) for the proposed SIMISGEST-VR tasks. Undergraduate students (n=100, reference group), surgical residents (n=20), and experts in minimally invasive surgery (n=28) took part in the study. After answering a demographic questionnaire and watching a video of the tasks to be performed, they individually repeated each task 10 times with each hand. The simulator provided concurrent, immediate, and terminal feedback and obtained the task metrics (time and score). From the reference group, 29 undergraduate students were randomly selected to perform the tasks 6 months later in order to determine test-retest reliability. Results Evidence from multiple sources, including strong intrarater reliability and internal consistency, considerable evidence for the hypothesized consequences of testing, and partial confirmation for relations to other variables, supports the validity of the scores and the metrics used to train and teach basic psychomotor skills for minimally invasive surgery via a new low-cost portable simulator that utilizes interaction technology mediated by gestures. Conclusions The results obtained provided multiple sources of evidence to validate SIMISGEST-VR tasks aimed at training novices with no prior experience and enabling them to learn basic psychomotor skills for minimally invasive surgery.

Abstract
OBJECTIVES To evaluate the effect of simulator fidelity on procedure skill training through a review of existing studies. METHODS MEDLINE, OVID and EMBASE databases were searched between January 1990 and January 2019. Search terms included "simulator fidelity and comparison" and "low fidelity" and "high fidelity" and "comparison" and "simulator". Author classification of low- and high-fidelity was used for non-laparoscopic procedures. Laparoscopic simulators are classified using a proposed schema. All included studies used a randomized methodology with two or more groups and were written in English. Data was abstracted to a standard data sheet and critically appraised from 17 eligible full papers. RESULTS Of 17 studies, eight were for laparoscopic and nine for other skill training. Studies employed evaluation methodologies, including subjective and objective measures. The evaluation was conducted once in 13/17 studies and before-after in 4/17. Didactic training only or control groups were used in 5/17 studies, while 10/17 studies included two groups only. Skill acquisition and simulator fidelity were different for the level of training in 1/17 studies. Simulation training was followed by clinical evaluation or a live animal evaluation in 3/17 studies. Low-fidelity training was not inferior to training with a high-fidelity simulator in 15/17 studies. CONCLUSIONS Procedure skill after training with low fidelity simulators was not inferior to skill after training with high fidelity simulators in 15/17 studies. Some data suggest that the effectiveness of different fidelity simulators depends on the level of training of participants and requires further study.

Abstract
Laparoscopic surgery (MIS) requires additional psychomotoric skills (basic skills) Acquisition of MIS basic skills by the video box trainer Lübecker Toolbox. Simulation of laparoscopic demands outside the operation room. MIS training outside the operation room prior to first operations on patients. Implementation of MIS training into the surgical residency curriculum.
Background Minimally invasive surgery (MIS) procedures require special psychomotoric skills. Learning of these MIS basic skills is often performed in the operating room (OR). This is economically inefficient and could be improved in terms of patient safety. Against the background of this problem, various MIS simulators have been developed to train MIS basic skills outside the OR. Aim of this study is to evaluate to what extent MIS training programs and simulators improve the residents’ skills in performing their first MIS procedures on patients. Method The current multicentric RCT will be performed with surgical residents without prior active experience in MIS (n = 14). After the participants have completed their first laparoscopic cholecystectomy as baseline evaluation (CHE I), they will be randomized into two groups: 1) The intervention group will perform the Lübeck Toolbox curriculum, whereas 2) the control group will not undergo any MIS training. After 6 weeks, both groups will perform the second laparoscopic CHE (CHE II). Changes or improvements in operative performance (between CHE I and CHE II) will be analyzed and evaluated according to the Global Operative Assessment of Laparoscopic Skill (GOALS) Score (primary endpoint). Discussion The multicentric randomized controlled trial will help to determine the value of MIS training outside the operation room. Proof of effectiveness in practice transfer could be of considerable relevance with regard to an integration of MIS training programs into surgical education.

Abstract
In recent years, there has been an increasing interest in employing simulation methodology for teaching surgical skills. Supposedly, skills achieved in the simulation arena, should lead to an improvement of surgical performance in the operating room. In this article we aim to summarise those areas of simulation-based research that relate to paediatric surgery; we present the current evidence behind low-fidelity simulation and computer-based simulation in improving the acquisition of surgical skills.

Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that delivers constant, low electrical current resulting in changes to cortical excitability. Prior work suggests it may enhance motor learning giving it the potential to augment surgical technical skill acquisition. OBJECTIVES The aim of this study was to test the efficacy of tDCS, coupled with motor skill training, to accelerate laparoscopic skill acquisition in a pre-registered (NCT03083483), double-blind and placebo-controlled study. We hypothesized that relative to sham tDCS, active tDCS would accelerate the development of laparoscopic technical skills, as measured by the Fundamentals of Laparoscopic Surgery (FLS) Peg Transfer task quantitative metrics. METHODS In this study, sixty subjects (mean age 22.7 years with 42 females) were randomized into sham or active tDCS in either bilateral primary motor cortex (bM1) or supplementary motor area (SMA) electrode configurations. All subjects practiced the FLS Peg Transfer Task during six 20-min training blocks, which were preceded and followed by a single trial pre-test and post-test. The primary outcome was changes in laparoscopic skill performance over time, quantified by group differences in completion time from pre-test to post-test and learning curves developed from a calculated score accounting for errors. RESULTS Learning curves calculated over the six 20-min training blocks showed significantly greater improvement in performance for the bM1 group than the sham group (t = 2.07, p = 0.039), with the bM1 group achieving approximately the same amount of improvement in 4 blocks compared to the 6 blocks required of the sham group. The SMA group also showed greater mean improvement than sham, but exhibited more variable learning performance and differences relative to sham were not significant (t = 0.85, p = 0.400). A significant main effect was present for pre-test versus post-test times (F = 133.2, p < 0.001), with lower completion times at post-test, however these did not significantly differ for the training groups. CONCLUSION Laparoscopic skill training with active bilateral tDCS exhibited significantly greater learning relative to sham. The potential for tDCS to enhance the training of surgical skills, therefore, merits further investigation to determine if these preliminary results may be replicated and extended.

Abstract
PURPOSE OF REVIEW Postgraduate medical training has evolved considerably from an emphasis on hands-on, autonomous learning to a paradigm where simulation technologies are used to introduce and augment certain skill sets. This review is intended to provide an update on surgical simulators and tools for urological trainee education. RECENT FINDINGS We provide an overview of simulation platforms for robotics, endoscopy, and laparoscopic practice and training. In general, these simulators provide face, content, and construct validity. Various educational and evaluation tools have been adopted. Simulation platforms have been developed for technical and non-technical surgical skills, educational bootcamps, and tools for evaluation and feedback. While trainees find the opportunity to practice their skills beneficial, there may be difficulty with access due to cost and availability. Additionally, there is a need for more objective metrics demonstrating improvement in skill or patient outcome.

Abstract
Introduction Beneficial effects of music have been described on several cognitive domains, task performance, stress, anxiety and pain. Greater surgical skill is a factor that has been associated with improved patient outcome. The aim of this systematic review is to assess the effect of music on surgical performance. Methods An exhaustive literature search was performed. The following databases were searched: Embase, Medline Ovid, Web of Science, Cochrane CENTAL, PsycINFO Ovid, CINAHL EBSCOhost, ERIC EBSCOhost and Google Scholar. All prospective studies that assessed the effect of a music intervention compared to either another auditory condition or silence on surgical performance were included in a qualitative synthesis. The study was registered in the PROSPERO-database (CRD42018092021). Results The literature search identified 3492 articles of which 9 studies (212 participants) were included. Beneficial effects of music were reported on time to task completion, instrument handling, quality of surgical task performance and general surgical performance. Furthermore, a beneficial effect of music on muscle activation was observed. Conclusion Although beneficial effects of music on surgical performance have been observed, there is insufficient evidence to definitively conclude that music has a beneficial effect on surgical performance in the simulated setting. Future studies should be conducted using greater numbers of participants focusing on a more limited range of tasks, as well as validation in the live operating environment.

Laparoscopic Simulation in Reverse and Side Alignment Impact on Forward Alignment Performance: A Randomized Controlled Trial. Surg Endosc 2019; 34:298-303. [PMID: 30927126 DOI: 10.1007/s00464-019-06766-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2018] [Accepted: 03/18/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND The influence of visual-spatial discordance during training on laparoscopic skills is poorly understood. It has been proposed that training in visual-spatial discordant situations can improve performance in the forward alignment, which was the basis of our hypothesis. Our study's aim was to conduct a randomized control trial to explore the impact of simulated training in visual-spatial discordant situations on forward alignment performance. METHODS The participants were 80 medical students who were randomized into four groups. Group A served as the control and performed all peg transfers in the forward alignment. Groups B, C, and D experienced varied rounds of either increasing or decreasing sensorimotor discordance. The students were trained and tested using the peg transfer task used in the Fundamentals of Laparoscopic Surgery curriculum. Based on the group, each student performed 10 peg transfer practice rounds in their assigned alignment. After each practice session, each student was tested and scored in forward alignment performance. A baseline test, followed by three practice sessions, and three tests were done. RESULTS Group A (control) demonstrated a statistically significant overall increase in scoring of 37.1% from baseline when compared to the final test. Groups B, C, and D showed improvements of 3.7%, 27.1%, and 19.3%, respectively, between baseline and the final test, yet none demonstrated consistent linear improvements. On multi-variate analysis, students who practiced in the side or reverse alignment positions scored 25 and 37 points lower, respectively, than students who practiced in the forward alignment. CONCLUSION Our study suggests that training in visual-spatial discordant conditions does not lead to the development of forward alignment laparoscopic skills. This could have important implications when developing future laparoscopic skills training curriculums. To our knowledge, this is the largest study to date assessing the impacts of training in visual-spatial discordance situations on performance in the forward alignment.

Abstract
Objective To determine whether wrist motion measured by a smartphone application can be used as a performance metric for a simulated airway procedure requiring both wrist and finger dexterity. We hypothesized that this accelerometer application could detect differences between novices and experienced surgeons performing simulated cricothyrotomy. Setting Academic medical center. Study Design Prospective pilot cohort study. Methods Voluntary surgeons and nonsurgeons were recruited. After viewing a training video, smartphones with accelerometer applications were attached to both wrists while subjects performed a cricothyrotomy on a validated task trainer. Procedure time and motion parameters, including average resultant acceleration (ARA), total resultant acceleration (TRA), and suprathreshold acceleration events (STAEs), were collected for dominant and nondominant hands. Subjects were stratified by prior experience. Blinded experts scored each performance using Objective Structured Assessment of Technical Skills (OSATS), and t tests were used to compare performance. Results Thirty subjects were enrolled. Median age was 26 years, and 20 subjects were male. In the dominant hand, significant differences were seen between novice and experienced surgeons in TRA (P = .005) and procedure time (P = .006), while no significant differences were seen in STAEs (P = .42) and ARA (P = .33). In the nondominant hand, all variables were significantly different between the 2 groups: STAEs (P = .012), ARA (P = .007), TRA (P = .004), and procedure time (P = .006). Conclusions Wrist motion measured by a low-cost smartphone application can distinguish between novice and experienced surgeons performing simulated airway surgery. This tool provides cost-effective and objective performance feedback.

Abstract
With the development and ubiquitous use of minimally invasive surgery, the advanced laparoscopic skills such as suture is essential for performing gastrointestinal procedures. However, the steep learning curve and lack of standardized training make most residents underprepared for laparoscopic suture. Moreover, the current simulation-based training is inadequate for trainees to master these advanced skills. Thus, there is a need for laparoscopic suture training modeled with cognitive knowledge, approachable techniques and standardized steps. Here, we present a suture training curriculum with video demonstration. In this study, we developed a suture training curriculum, which are divided into two categories depending on its difficulty and application. Basic techniques are designed for novice to master the basic suture skills, and it also shortens the learning curve of advanced suture techniques. Advanced techniques focused on the application of suture in specific circumstances. Also, it could prepare residents for more complex procedures. In order to increase the efficacy of suture training, we recommend a learning method similar to Peyton's four-step approach, personalized video feedback and spaced learning in our curricula. This article demonstrates the various laparoscopic techniques and their applications from simple to complex, with a view to help residents in training. Also, the training curricula and recommendations will further help residents to improve efficiently. Thus, we recommend to incorporate the curricula into suture training courses and surgical programs.

A randomized control trial to evaluate the importance of pre-training basic laparoscopic psychomotor skills upon the learning curve of laparoscopic intra-corporeal knot tying. ACTA ACUST UNITED AC 2017; 14:29.

Abstract
Background Training of basic laparoscopic psychomotor skills improves the acquisition of more advanced laparoscopic tasks, such as laparoscopic intra-corporeal knot tying (LICK). This randomized controlled trial was designed to evaluate whether pre-training of basic skills, as laparoscopic camera navigation (LCN), hand-eye coordination (HEC), and bimanual coordination (BMC), and the combination of the three of them, has any beneficial effect upon the learning curve of LICK. The study was carried out in a private center in Asunción, Paraguay, by 80 medical students without any experience in surgery. Four laparoscopic tasks were performed in the ENCILAP model (LCN, HEC, BMC, and LICK). Participants were allocated to 5 groups (G1-G5). The study was structured in 5 phases. In phase 1, they underwent a base-line test (T1) for all tasks (1 repetition of each task in consecutive order). In phase 2, participants underwent different training programs (30 consecutive repetitions) for basic tasks according to the group they belong to (G1: none; G2: LCN; G3: HEC; G4: BMC; and G5: LCN, HEC, and BMC). In phase 3, they were tested again (T2) in the same manner than at T1. In phase 4, they underwent a standardized training program for LICK (30 consecutive repetitions). In phase 5, they were tested again (T3) in the same manner than at T1 and T2. At each repetition, scoring was based on the time taken for task completion system. Results The scores were plotted and non-linear regression models were used to fit the learning curves to one- and two-phase exponential decay models for each participant (individual curves) and for each group (group curves). The LICK group learning curves fitted better to the two-phase exponential decay model. From these curves, the starting points (Y0), the point after HEC training/before LICK training (Y1), the Plateau, and the rate constants (K) were calculated. All groups, except for G4, started from a similar point (Y0). At Y1, G5 scored already better than the others (G1 p = .004; G2 p = .04; G3 p < .0001; G4 NS). Although all groups reached a similar Plateau, G5 has a quicker learning than the others, demonstrated by a higher K (G1 p < 0.0001; G2 p < 0.0001; G3 p < 0.0001; and G4 p < 0.0001). Conclusions Our data confirms that training improves laparoscopic skills and demonstrates that pre-training of all basic skills (i.e., LCN, HEC, and BMC) shortens the LICK learning curve.

Abstract
OBJECTIVE Urology practice has undergone several changes in recent years mainly related to novel technologies introduced. We aimed to get the residents' perspective on the current residency program in Israel and propose changes in it. METHODS A web-based survey was distributed among urology residents. RESULTS 61 residents completed the survey out of 95 to whom it was sent (64% compliance). A total of 30% replied that the 9 months of mandatory general surgery rotation contributed to their training, 48% replied it should be shortened/canceled, and 43% replied that the Step A exam (a mandatory written certifying exam) in general surgery was relevant to their training. A total of 37% thought that surgical exposure during the residency was adequate, and 28% considered their training "hands-on." Most non-junior residents (post-graduate year 3 and beyond) reported being able to perform simple procedures such as circumcision and transurethral resections but not complex procedures such as radical and laparoscopic procedures. A total of 41% of non-junior residents practice at a urology clinic. A total of 62% of residents from centers with no robotics replied its absence harmed their training, and 85% replied they would benefit from a robotics rotation. A total of 61% of residents from centers with robotics replied its presence harmed their training, and 72% replied they would benefit from an open surgery rotation. A total of 82% of the residents participated in post-graduate courses, and 81% replied they would engage in a clinical fellowship. CONCLUSION Given the survey results we propose some changes to be considered in the residency program. These include changes in the general surgery rotation and exam, better surgical training, possible exchange rotations to expose residents to robotic and open surgery (depending on the availability of robotics in their center), greater out-patient urology clinic exposure, and possible changes in the basic science period.

Abstract
Background Training of basic laparoscopic psychomotor skills improves both acquisition and retention of more advanced laparoscopic tasks, such as laparoscopic intra-corporeal knot tying (LICK). This randomized controlled trial (RCT) was performed to evaluate the effect of different pre-training programs in hand-eye coordination (HEC) upon the learning curve of LICK. Results The study was performed in a private center in Asunción, Paraguay, by 60 residents/specialists in gynaecology with no experience in laparoscopic surgery. Participants were allocated in three groups. In phase 1, a baseline test was performed (T1, three repetitions). In phase 2, participants underwent different training programs for HEC (60 repetitions): G1 with both the dominant hand (DH) and the non-dominant hand (NDH), G2 with the DH only, G3 none. In phase 3, a post HEC/pre LICK training test was performed (T2, three repetitions). In phase 4, participants underwent a standardized training program for LICK (60 repetitions). In phase 5, a final test was performed (T3, three repetitions). The score was based on the time taken for task completion system. The scores were plotted and non-linear regression models were used to fit the learning curves to one- and two-phase exponential decay models for each participant (individual curves) and for each group (group curves). For both HEC and LICK, the group learning curves fitted better to the two-phase exponential decay model. For HEC with the DH, G1 and G2 started from a similar point, but G1 reached a lower plateau at a higher speed. In G1, the DH curve started from a lower point than the NDH curve, but both curves reached a similar plateau at comparable speeds. For LICK, all groups started from a similar point, but immediately after HEC training and before LICK training, G1 scored better than the others. All groups reached a similar plateau but with a different decay, G1 reaching this plateau faster than the others groups. Conclusions This study demonstrates that pre-training in HEC with both the DH and the NDH shortens the LICK learning curve.

Abstract
Laparoscopic surgical training using a box trainer facilitates mastery of laparoscopic surgery. Few studies have investigated whether visualizing the surgical field in the box trainer improves performance of laparoscopic surgical procedures during laparoscopic training. An original box trainer equipped with a transparent top made of mesh covered with a latticed structure was developed and used for evaluation of novices during laparoscopic training. Three tasks (levels 1 to 3) involving organ handling while setting the surgical field were arranged to evaluate the efficacy of training. Forty-five students were divided into three groups: group A, students without practical training; group B, students trained using the covered box trainer; and group C, students trained using the transparent box trainer. Completion time of each task before and after training was compared. Training significantly reduced the operating time, with a significant difference between the level 1 task and the levels 2 (P<.001) and 3 (P<.0001) tasks. There was no significant difference in operating time between the levels 2 and 3 tasks. Overall time reduction rate in group C was significantly shorter than that in group A, but not in group B. The time reduction rate for the level 3 task was lowest in group C, with a statistically significant difference existing in group A (P<.001). Visual feedback during surgery through the transparent top of the laparoscopic box trainer helped reduce the learning time required to carry out laparoscopic surgery.

Abstract
BACKGROUND Laparoscopic assistance is often entrusted to a less experienced resident, medical student, or operating room nurse. Data regarding laparoscopic training for operating room nurses are not available. OBJECTIVES The aim of the study was to analyse the initial performance level and learning curves of operating room nurses in basic laparoscopic surgery compared with medical students and surgical residents to determine their ability to assist with this type of procedure. DESIGN The study was designed to compare the initial virtual reality performance level and learning curves of user groups to analyse competence in laparoscopic assistance. PARTICIPANTS The study subjects were operating room nurses, medical students, and first year residents. METHODS Participants performed three validated tasks (camera navigation, peg transfer, fine dissection) on a virtual reality laparoscopic simulator three times in 3 consecutive days. Laparoscopic experts were enrolled as a control group. Participants filled out questionnaires before and after the course. RESULTS Nurses and students were comparable in their initial performance (p>0.05). Residents performed better in camera navigation than students and nurses and reached the expert level for this task. Residents, students, and nurses had comparable bimanual skills throughout the study; while, experts performed significantly better in bimanual manoeuvres at all times (p<0.05). CONCLUSION The included user groups had comparable skills for bimanual tasks. Residents with limited experience reached the expert level in camera navigation. With training, nurses, students, and first year residents are equally capable of assisting in basic laparoscopic procedures.

Abstract
CONTEXT Hysteroscopy is one of the most common gynaecological procedure. Training for diagnostic and operative hysteroscopy can be achieved through numerous previously described models like animal models or virtual reality simulation. We present our novel combined model associating virtual reality and bovine uteruses and bladders. STUDY DESIGN End year residents in obstetrics and gynaecology attended a full day workshop. The workshop was divided in theoretical courses from senior surgeons and hands-on training in operative hysteroscopy and virtual reality Essure® procedures using the EssureSim™ and Pelvicsim™ simulators with multiple scenarios. Theoretical and operative knowledge was evaluated before and after the workshop and General Points Averages (GPAs) were calculated and compared using a Student's T test. RESULTS GPAs were significantly higher after the workshop was completed. The biggest difference was observed in operative knowledge (0,28 GPA before workshop versus 0,55 after workshop, p<0,05). All of the 25 residents having completed the workshop applauded the realism an efficiency of this type of training. The force feedback allowed by the cattle uteruses gives the residents the possibility to manage thickness of resection as in real time surgery. Furthermore, the two-horned bovine uteruses allowed to reproduce septa resection in conditions close to human surgery CONCLUSION: Teaching operative and diagnostic hysteroscopy is essential. Managing this training through a full day workshop using a combined animal model and virtual reality simulation is an efficient model not described before.

Abstract
Question: Endoscopy is an integral part of surgical gynaecology and is playing an increasingly important role in ensuring adequate gynaecological training in the context of specialty training in general. At present, little is known about the expectations and notions of young junior doctors with respect to endoscopic training. For this reason, junior doctors throughout Germany were surveyed on this topic and asked to share their opinions. Methods: Using an anonymized standardized survey, the following information was elicited: importance of endoscopic training, willingness to take courses, expectations for instructors and the hospital, ideas about the number of required operations, both as a surgical assistant and as a surgeon, as well as satisfaction with the current status of training. The questionnaires were sent via the Young Forum (Junges Forum) of the German Society of Gynaecology and Obstetrics (DGGG) and the newsletter of the Working Group for Gynaecological Endoscopy (AGE). Results: The evaluation of the study was based on 109 completed questionnaires. The resident junior doctors were 31 years old on average and were in their third to fourth year of their specialty training on average. The majority of the participants (87 %) considered the learning of endoscopic techniques to be very important and advocated regular participation in endoscopy training courses. Among the participants, 48 % were prepared to invest up to €1500 of their own funds to attend courses up to twice a year during the entire specialty training period. The expectations of the instructors and institutions focused on technical expertise, the willingness and time for teaching and on the number and range of surgical procedures, followed by being granted leave for the courses and having costs covered for the courses. Thirty-eight per cent stated that their expectations had been completely or mostly met and 62 % said they had been met in part or inadequately. Eighty-three per cent of the respondents reported that they would change specialty training institutions in order to achieve their own goals in the context of specialty training. Conclusions: This study presents data for the first time on the satisfaction of young junior doctors and their expectations for endoscopic specialty training. The residents exhibited a high level of interest in endoscopy and a high level of willingness to actively shape the specialty training, including course participation. However, there appears to be a great deal of room for improvement for endoscopic specialty training, independent of the current training institution, training year or sex of the junior doctors.

Abstract
Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination.

Safe introduction of laparoscopic and retroperitoneoscopic nephrectomy in clinical practice: impact of a modular training program. World J Urol 2016; 35:761-769. [PMID: 27530745 DOI: 10.1007/s00345-016-1921-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Accepted: 08/08/2016] [Indexed: 02/06/2023] Open
Abstract
PURPOSE To describe and validate a novel modular training scheme (MTS) for trans-peritoneal laparoscopic nephrectomy (LN) and retroperitoneoscopic nephrectomy (RN). METHODS Four consultant urologists attended a Masterclass in "Advanced Laparoscopic and Robotic Surgery," certified by the University of Turin (IT). The Masterclass was based on a supervised MTS, which involved progressive, proficiency-based training through nine and seven steps for LN and RN, respectively. After becoming proficient in all the steps, each trainee performed a minimum of five procedures as first operator under direct observation of the mentor in the training centre. Then, each trainee independently performed 10 LN and 10 RN at his home institution. The surgical outcomes were compared with those from a contemporary series of procedures performed by the mentor. RESULTS All trainees successfully completed the 12-week MTS program. Median number of training cases to become competent in trans-peritoneal LN and RN was 13.0 (IQR 11.5-20.5) and 23.5 (IQR 19.5-32.0), respectively. A significantly higher rate of conversion to open surgery was observed for RNs independently performed by the trainees in their hospital compared to the mentor (p = 0.033). Failure to progress due to difficult anatomical orientation and abdominal wall bleeding during dissection of retroperitoneal space were the most frequent reasons of conversion. CONCLUSIONS A 12-week intensive modular program allows to achieve proficiency in performing independently LN and a RN after a median of 13 and 23.5 cases, respectively. Therefore, these procedures can be safely introduced and implemented in clinical practice within a relatively short time.

Abstract
Simulation in surgical training is playing an increasingly important role as postgraduate medical education programs navigate an environment of increasing costs of education, increased attention on patient safety, and new duty hour restrictions. In obstetrics and gynecology, simulation has been used to teach many procedures; however, it lacks a standardized curriculum. Several different simulators exist for teaching various routes and aspects of hysterectomy. This article describes how a formal framework of increasing levels of competencies can be applied to simulation in teaching the procedure of hysterectomy.

Abstract
OBJECTIVES The purpose of this study was to assess the contribution of complex tasks on virtual reality simulator (VRS) for novice surgeons in laparoscopy learning. MATERIALS AND METHODS Fifty-five medical students were prospectively randomized in two groups (A: basic skills, n=28 and B: basic and complex skills, n=27) and then trained during two sessions on VRS. Evaluations took place before and after each training. These evaluations consisted of the achievement of an intracorporeal suture, recorded on video, with the left then with the right hand. Two independent experts evaluated those gestures blindly. RESULTS A significant progression in terms of times and technical scores was observed in both groups between the first and the last evaluations (P between 0.001 and 0.04). Students in group B improved slower and longer than those in group A. However, left and right hands results confused did not highlight significant differences between the two groups. At the third session, the first hand to train is significantly faster in group B than in group A (P=0.04). CONCLUSION This study found only a late and minimal impact of complex skills to reduce the execution time of intracorporeal suture. It also showed an slower and longer overall progression for those who use them compared to subjects using basic skills only.

Abstract
This study compared virtual reality (VR) training with low cost-blended learning (BL) in a structured training program.Training of laparoscopic skills outside the operating room is mandatory to reduce operative times and risks.Laparoscopy-naïve medical students were randomized in 2 groups stratified for sex. The BL group (n = 42) used E-learning for laparoscopic cholecystectomy (LC) and practiced basic skills with box trainers. The VR group (n = 42) trained basic skills and LC on the LAP Mentor II (Simbionix, Cleveland, OH). Each group trained 3 × 4 hours followed by a knowledge test concerning LC. Blinded raters assessed the operative performance of cadaveric porcine LC using the Objective Structured Assessment of Technical Skills (OSATS). The LC was discontinued when it was not completed within 80 min. Students evaluated their training modality with questionnaires.The VR group completed the LC significantly faster and more often within 80 min than BL (45% v 21%, P = .02). The BL group scored higher than the VR group in the knowledge test (13.3 ± 1.3 vs 11.0 ± 1.7, P < 0.001). Both groups showed equal operative performance of LC in the OSATS score (49.4 ± 10.5 vs 49.7 ± 12.0, P = 0.90). Students generally liked training and felt well prepared for assisting in laparoscopic surgery. The efficiency of the training was judged higher by the VR group than by the BL group.VR and BL can both be applied for training the basics of LC. Multimodality training programs should be developed that combine the advantages of both approaches.

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 is an option to supplement standard training. However, the value of this modality on trainees with limited prior laparoscopic experience is unknown. OBJECTIVES To compare the benefits and harms of box model training for surgical trainees with limited prior laparoscopic experience versus standard surgical training or supplementary animal model training. 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 planned to include all randomised clinical trials comparing box model trainers versus other forms of training including standard laparoscopic training and supplementary animal model training in surgical trainees with limited prior laparoscopic experience. We also planned to include 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 5. For each outcome, we calculated the risk ratio (RR), mean difference (MD), or standardised mean difference (SMD) with 95% confidence intervals (CI) based on intention-to-treat analysis whenever possible. MAIN RESULTS We identified eight trials that met the inclusion criteria. One trial including 17 surgical trainees did not contribute to the meta-analysis. We included seven trials (249 surgical trainees belonging to various postgraduate years ranging from year one to four) in which the participants were randomised to supplementary box model training (122 trainees) versus standard training (127 trainees). Only one trial (50 trainees) was at low risk of bias. The box trainers used in all the seven trials were video trainers. Six trials were conducted in USA and one trial in Canada. The surgeries in which the final assessments were made included laparoscopic total extraperitoneal hernia repairs, laparoscopic cholecystectomy, laparoscopic tubal ligation, laparoscopic partial salpingectomy, and laparoscopic bilateral mid-segment salpingectomy. The final assessments were made on a single operative procedure.There were no deaths in three trials (0/82 (0%) supplementary box model training versus 0/86 (0%) standard training; RR not estimable; very low quality evidence). The other trials did not report mortality. The estimated effect on serious adverse events was compatible with benefit and harm (three trials; 168 patients; 0/82 (0%) supplementary box model training versus 1/86 (1.1%) standard training; RR 0.36; 95% CI 0.02 to 8.43; very low quality evidence). None of the trials reported patient quality of life. The operating time was significantly shorter in the supplementary box model training group versus the standard training group (1 trial; 50 patients; MD -6.50 minutes; 95% CI -10.85 to -2.15). The proportion of patients who were discharged as day-surgery was significantly higher in the supplementary box model training group versus the standard training group (1 trial; 50 patients; 24/24 (100%) supplementary box model training versus 15/26 (57.7%) standard training; RR 1.71; 95% CI 1.23 to 2.37). None of the trials reported trainee satisfaction. The operating performance was significantly better in the supplementary box model training group versus the standard training group (seven trials; 249 trainees; SMD 0.84; 95% CI 0.57 to 1.10).None of the trials compared box model training versus animal model training or versus different methods of box model training. AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether laparoscopic box model training reduces mortality or morbidity. There is very low quality evidence that it improves technical skills compared with standard surgical training in trainees with limited previous laparoscopic experience. It may also decrease operating time and increase the proportion of patients who were discharged as day-surgery in the first total extraperitoneal hernia repair after box model training. However, the duration of the benefit of box model training is unknown. Further well-designed trials of low risk of bias and random errors are necessary. Such trials should assess the long-term impact of box model training on clinical outcomes and compare box training with other forms of training.
