Laparoscopic surgery has been developed rapidly in recerlt years all over the world.Its indication has been enlarged with the rapid advancement and development of opticalsystem, disposable devices and other operative instruments. It have brought the revolutionand the conceptual changes xn surgery. Recently, the indication of laparoscopxc surgery hasbeen extended to malignancy such as early gastric cancer and colorectal cancer. However, complicated procedures in laparoscopic surgery which require precise maneuver, suturingor knot tying are still difficult for surgeons, and this fact prevents its further popularizationand the further extension of its indication. In order to overcame this barrier and makelaparoscopic surgery more easier and more surgeon-friendly, we have been introducing ordeveloping several new technologies since 1994, collaborating with the Faculty of Technol-ogy and Science, Keio University and several companies. They are 3-D, head mountdisplay, tele-education system, virtual reality educational system, solo-surgery with voicecontrol robotic system and maser-slave rnanipulator. Some are still under developmentand some are already clinically applied in our institute. with these technologies, laparo-scopic surgery will become easier and safer to perform, and the indication of Iaparoscopicsurgery will extend more widely in future.
