“…It is essential that laparoscopy can be performed promptly and safely, and several studies illustrate the benefits of laparoscopic simulator training for both basic 6,28,29 and advanced surgical skills training. [30][31][32] Early introduction of medical students to basic surgical skills training may also create an increased interest in surgery. 33 In a recent study, a virtual basic laparoscopic skills trainer that simulates the Fundamentals of Laparoscopic Surgery Trainer Box's 5 tasks was tested, which was presented to have the potential of supporting the training efforts for suturing skills.…”

Background. Our aim was to determine if a newly designed Najar needle holder (NNH) shortens the time for novices to improve advanced laparoscopy (AL) techniques (suturing/knot tying), compared with a conventional macro needle holder (MNH) in a simulator. Furthermore, we aimed to validate a new video scoring system determining AL skills. Methods. Forty-six medical students performed identical surgical tasks in a prospective, crossover study evaluating AL skills (NNH vs MNH). All subjects performed a double-throw knot, 2 single-throw knots following 3 running sutures in the Simball Box (SB) simulator. After resting, subjects switched needle holders. All tasks were videotaped and analyzed using SB software and by 2 independent reviewers using the Objective Video Evaluation Scoring Table (OVEST). Trial performance expressed as SB Overall Score (SBOS) and OVEST. Results. In the group starting with NNH (followed by MNH) OVEST was consistently high during both trials (median = 12.5, range = 6.5-18.0, and median = 13.5, range = 6.5-21.0; P = .2360). However, in the group starting with MNH, OVEST improved significantly when the participants changed to NNH (median = 10.0, range = 2.5-19.5, vs median = 14.5, range = 4.5-18.0; P = .0003); an improvement was also found with SBOS (median = 37%, range = 27% to 92%, vs median = 48%, range = 34% to 70%; P = .0289). In both trials, both independent reviewers’ OVEST measures correlated well: Trial 1: β = 0.97, P < .0001; and Trial 2: β = 0.95, P < .0001. A correlation also existed between SBOS and OVEST in both trials (β = 2.1, P < .0001; and β = 1.9, P = .0002). Conclusions. This study indicates a significantly higher improvement in laparoscopic suturing skills in novices training AL skills using NNH compared with MNH. Starting early, AL training in novices using NNH is a feasible option. Furthermore, OVEST used in experimental settings as an evaluation tool is comparable with the validated SBOS.

“…The use of synthetic material to simulate tissues and vessels can offer residents an opportunity to practice procedural steps and simultaneously gain experience in the handling and manipulation of surgical tools ( Fig. 1 ) [ 21 ]. Common materials, such as silicone and wax, are more affordable than virtual reality [ 34 ].…”

“…As an alternative to the use of cadavers and as a method to cut costs, many institutions use freshly excised tissue following surgeries such as abdominoplasty and body contouring. This limits practice to specific techniques as opposed to procedures, but can be very useful for teaching competence in surgical tools [ 21 , 37 ]. Concern over the use of cadavers is commonplace in regards to their potential to become reservoirs for communicable disease.…”

Current status of simulation training in plastic surgery residency programs: A review

Increased emphasis on competency-based learning modules and widespread departure from traditional models of Halstedian apprenticeship have made surgical simulation an increasingly appealing component of medical education. Surgical simulators are available in numerous modalities, including virtual, synthetic, animal, and non-living models. The ideal surgical simulator would facilitate the acquisition and refinement of surgical skills prior to clinical application, by mimicking the size, color, texture, recoil, and environment of the operating room. Simulation training has proven helpful for advancing specific surgical skills and techniques, aiding in early and late resident learning curves. In this review, the current applications and potential benefits of incorporating simulation-based surgical training into residency curriculum are explored in depth, specifically in the context of plastic surgery. Despite the prevalence of simulation-based training models, there is a paucity of research on integration into resident programs. Current curriculums emphasize the ability to identify anatomical landmarks and procedural steps through virtual simulation. Although transfer of these skills to the operating room is promising, careful attention must be paid to mastery versus memorization. In the authors’ opinions, curriculums should involve step-wise employment of diverse models in different stages of training to assess milestones. To date, the simulation of tactile experience that is reminiscent of real-time clinical scenarios remains challenging, and a sophisticated model has yet to be established.

“…Interestingly, simulators are not only useful for learning. Warming up in simulators brings enhanced performance [36]. Following principles of aviation applied to surgery [37], surgeons should keep periodic training in simulators.…”

Background: It is unclear if there is a natural transition from robotic to laparoscopic surgery with transfer of abilities. This study aims to measure the performance and learning of basic robotic tasks in a simulator of individuals with different surgical background. Method: Three groups were tested for robotic dexterity: (a) experts in laparoscopic surgery (n=6), (b) experts in open surgery (n=6), and (c) non-medical subjects (n=4). All individuals were aged between 40 -50 years. Five repetitions of 4 different simulated tasks were performed: spatial vision, bimanual coordination, hand-foot-eye coordination and motor skill. Results: Experts in laparoscopic surgery performed similar to non-medical individuals and better than experts in open surgery in 3 out of 4 tasks. All groups improved performance with repetition. Conclusions: Experts in laparoscopic surgery performed better than other groups but almost equally to non-medical individuals. Experts in open surgery had worst results. All groups improved performance with repetition.
