Abstract Objective: To compare the efficacy between motorized articulating instruments (AI) and rigid conventional laparoscopic instruments (CI) in chancing visualizing systems, respectively two-dimension (2D) and three-dimension (3D). Methods: Sixty physicians were divided into three groups according to their previous experience as medical students (Group 1), residents (Group 2), and expert surgeons (Group 3). Four experimental sets were created, respectively CI-2D visualizing system (CI-2D), CI-3D visualizing system (CI-3D), AI-2D visualizing system (AI-2D), and AI-3D visualizing system (AI-3D) platforms. European training in basic laparoscopic urological skills (E-BLUS) and anastomosis tasks (in total five tasks) was used. All participants were randomly required to perform tasks in each one of the technical platforms, except anastomosis exercises that were performed as the last exercises. Duration of tasks were measured, and predefined errors were counted. All these were recorded, and completion qualit...
