A new face-mounted display system: pilot trial of clinical application in therapeutic endoscopy
1First Department of Surgery, Tokyo Medical and Dental University, Japan. t.yoshida@libra.bekkoame.ne.jp
Background And Study Aims:
Since fiber endoscopes evolved into video endoscopes, there has been no remarkable progression in the optical system for endoscopy. The current optical system provided by fixed cathode-ray tube (CRT) display is a monitor-oriented system. In this study, we evaluate the practical usefulness of the face-mounted display (FMD), which provides us with an operator-oriented optical system.
Patients And Methods:
The FMD device, weighing 110 g, is designed for consumer video home use, consisting of two active matrix liquid crystal color panels with 180,000-pixel resolution. With the picture-in-picture capability, FMD provided us with image-navigated endoscopic procedure. Fourteen patients were enrolled in this study; seven patients for endoscopic mucosal resection, two for insertion of an esophageal metallic stent, three for clipping for the bleeding and two for dilatation of anastomotic strictures.
Results:
The FMD device allowed us to use an ultra large screen as if there has been a 62-inch screen 2 m ahead. During endoscopy, we could concentrate more on the procedures. There were no complications attributable to the use of the device.
Conclusion:
We are convinced of a new evolution in the optical system for therapeutic endoscopy with the FMD device.
