A teleconference with three-dimensional surgical video presentation on the 'usual' Internet

Endoscopic surgery employing three-dimensional (3D) video images, such as a robotic surgery, has recently become common. However, the number of opportunities to watch such actual 3D videos is still limited due to many technical difficulties associated with showing 3D videos in front of an audience. A teleconference with 3D video presentations of robotic surgeries was held between our institution and a distant institution using a commercially available telecommunication appliance on the 'usual' Internet. Although purpose-built video displays and 3D glasses were necessary, no technical problems occurred during the presentation and discussion. This high-definition 3D telecommunication system can be applied to discussions about and education on 3D endoscopic surgeries for many surgeons, even in distant places, without difficulty over the usual Internet connection.
