BACKGROUND: The objective of this study was to compare the efficacy of the da Vinci robotic system using both the three-dimensional view (3D) and two-dimensional (2D) view options with traditional manually assisted laparoscopic techniques in performing standardized exercises. METHODS: To evaluate surgical efficiency in the use of robotically assisted and manual laparoscopic surgery for standardized exercises six, last-year medical students without any surgical experience were selected. The exercises consisted of placing rings over receptacles, grasping a free hanging suture and cutting three pieces of it, running a suture, and performing a surgical knot. Each student performed the exercise twice. The median times needed for completion of the exercises and the median number of errors in performing the tasks were noted. RESULTS: The unexperienced students performed the standardized tasks significantly quicker and with fewer errors when assisted by the da Vinci robot in the 3D optical display mode, as compared with traditional manually assisted laparoscopic surgery. Even when the 2D mode was selected, a significant advantage favoring the da Vinci robotic system was seen both in time and efficacy for most exercises. When the 3D and 2D modes were compared, time differences in favor of the 3D mode remained, but a significant difference in efficacy favoring the 3D mode was seen only in one exercise (exercise 2: suture cutting). CONCLUSIONS: The da Vinci robotic system permits standardized minimal invasive surgical exercises to be performed quicker and more efficiently than traditional minimally invasive techniques. Therefore, with the aid of this robotic system, difficult laparoscopic interventions may become easier to perform, and indications for minimal invasive surgery may be expanded.

We have developed a remote control system for the scanning electron microscope (SEM). It is called Web-SEM and can be accessed by anyone through the Web browser. It is not necessary to install special software to control the SEM. Because the operating performance changes with the amount of traffic on the Internet, we have connected the Web-SEM to a LAN/Internet in order to overcome this. We have checked the performance of the remote control operation and we were able to perform focus adjustment, stage movement, etc. over the Internet by improving the method of operation and image transfer.
