Abstract
Background Previous studies have failed to establish clear advantages for the use of stereoscopic visualization systems in minimalaccess surgery The aim of this study was to objectively assess whether stereoscopic visualization improves performance on bench models using the da Vinci robotic system Methods Eleven surgeons carried out a series of four tasks Positional data streamed from the da Vinci system was analyzed by means of a previously validated customdesigned softwarepackage An independent blinded observer scored errors Statistical analysis included the Wilcoxon signed rank test A p 005 was deemed significant Results We found significant improvements in all tasks and for all parameters p 005 In addition a significantly lower number of errors was scored using the stereoscopic mode as compared to the standard twodimensional image p 0001 Conclusion Roboticassisted performance on bench models is more efficient and accurate using stereoscopic visualization
