Abstract :

Objective: The aim of this study was to assess performance carryover effects associated with different successive lateral camera rotations in the laparoscopic training environment. Background: Laparoscopy requires surgeons to adapt to disruptions of visuomotor mapping. A gradual adaptation process is hypothesized to be effective up to a given rotation threshold; this threshold may have performance implications for successive exposure to different lateral camera rotations. Method: Two experiments utilized a laparoscopic training task. Experiment I exposed novices to a subsequent rotation that was either 45[degrees] larger than one of the initial rotations of 45[degrees], 75[degrees], 105[degrees], and 135[degrees] or 45[degrees] smaller than one of the initial rotations of 90[degrees], 120[degrees], 150[degrees], and 180[degrees]. Experiment 2 exposed novices to either stepwise increasing rotations (0[degrees] to 180[degrees]) or stepwise decreasing rotations (180[degrees] to 0[degrees]). Results: Regarding Experiment I, performance generally improved for subsequent rotations that were 45[degrees] larger than the initial rotation, except for one condition (initial rotation, 105[degrees]; subsequent rotation, 150[degrees]). Performance generally improved for subsequent rotations that were 45[degrees] smaller than the initial rotation, except for one condition (initial rotation, 120[degrees]; subsequent rotation, 75[degrees]). Experiment 2 indicated worst performance at 120[degrees] for the increasing and decreasing conditions. This finding suggests an identical threshold for increasing and decreasing rotations, which is inconsistent with Experiment I results. Conclusion: Improved performance due to carryover effects from successive exposure to lateral camera rotations in the laparoscopic training environment is contingent on the specific camera rotations. Application: Supplementary laparoscopic training might be needed for surgeries that entail certain successive lateral camera rotations.
