Take-Home Laparoscopy Simulators in Pediatric Surgery: Is More Expensive Better?

Background: To increase complex minimally invasive skills (MIS), frequent training outside the clinical setting is of uttermost importance. This study compares two low-cost pediatric MIS simulators, which can easily be used preclinically. Materials and Methods: The LaparoscopyBoxx is a portable simulator without a tracking system, with costs ranging from €90 to €315. The EoSim simulator has a built-in camera and tracking system and costs range from €780 to €1800. During several pediatric surgical conferences and workshops (January 2017-December 2018), participants were asked to use both simulators. Afterward, they completed a questionnaire regarding their opinion on realism and didactic value, scored on a five-point Likert scale. Results: A total of 50 participants (24 experts and 25 target group, one unknown) evaluated one or both simulators. Both simulators scored well on the questionnaire. The LaparoscopyBoxx scored significantly better regarding the "on screen representation of the instrument actions" (mean 4.2 versus 3.5, P  = .001), "training tool for pediatric surgery" (mean 4.4 versus 3.9, P  = .005), and "appealing take-home simulator" (mean 4.6 versus 4.0, P  = .002). Conclusion: The simulators tested in this study were both regarded an appealing take-home simulator. The LaparoscopyBoxx scored significantly better than the EoSim, even though this is a low budget simulator without tracking capabilities.
