Comparison of learning curves and skill transfer between classical and robotic laparoscopy according to the viewing conditions: implications for training.

摘要: Abstract Background The purpose of this study was to evaluate the perceptual (2-dimensional [2D] vs. 3-dimensional [3D] view) and instrumental (classical robotic) impacts new robotic system on learning curves. Methods Forty medical students without any surgical experience were randomized into 4 groups laparoscopy with 3D-direct view or 2D-indirect view, in 3D 2D) repeated a laparoscopic task 6 times. After these repetitions, they performed 2 trials same technique but other viewing condition (perceptive switch). Finally, subjects last 3 never used (technical Subjects evaluated their performance answering questionnaire (impressions mastery, familiarity, satisfaction, self-confidence, difficulty). Results Our showed better improvement than 2D whatever aspect. Participants reported less self-confidence more difficulty classical conditions. Conclusions Robotic surgery improves learning, particularly by advantage. However, perceptive technical switches emphasize need adapt pursue training also traditional technology prevent risks conversion procedure.
