Zusammenfassung. Grundlagen: Wir untersuchten den Effekt des ,,virtual reality (VR) laparoscopy simulator (LapSim + )'' auf die Lernkurve bei laparoskopischer Chirurgie.Methodik: 14 Medizinstudenten wurden fü r ,,clip application'' randomisiert. Gruppe A (n ¼ 7) niedriger Schwierigkeitsgrad, Gruppe B (n ¼ 7) hoher Schwierigkeitsgrad. Beide Gruppen wurden nach 2 Monaten wieder getestet, entsprechend dem Schwierigkeitsgrad. Bei jedem Training am Simulator musste die Ü bung 10Â wiederholt werden.Ergebnisse: Beide Gruppen verbesserten sich im Vergleich zur ersten Trainingseinheit. Gruppe A hat das 2 Training schneller und blutä rmer beendet als Gruppe B. LernkurvenPlateau war in Gruppe A nach 6 Wiederholungen erreicht, solches war bei Gruppe B nicht zu beobachten.Schlussfolgerungen: Die Lernkurve scheint eher von der Schwierigkeit der Ü bung als von der Anzahl der Wiederholungen abhä ngig zu sein.Schlü sselwö rter: Computer-Simulation, Laparoskopie, chirurgische Ausbildung, minimal invasive Chirurgie.Summary. Background: The aim of this study was to determine the influence of different training levels with increasing complexity on the learning curve of a virtual reality (VR) laparoscopy simulator (LapSim + ). Furthermore, this study was designed to identify reacquisition of performance in medical students.Methods: 14 medical students in their final year without previous laparoscopic experience were randomized into two groups, both of which performed the ''clip application'' task.Group A (n ¼ 7) had parameter adjusted to an easy level of performance, while group B (n ¼ 7) was adjusted to a difficult level. Both groups were tested again at their respective level two months later. During both training sessions, each participant had to repeat the task ten times consecutively.Results: Both groups had improved parameter of performance when tested again after two months. Group A completed the second training session significantly faster than Group B and with less loss of blood. Parameter of performance plateaued in group A by the 6th repetition. However, such stable plateau was not reached in group B.Conclusions: This result suggests that steepness and plateau of a learning curve may be more dependent on the level of performance required by the particular training session rather than the number of repetitions during a session.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
