Purpose: We have been developing a navigation system using augmented reality technology and have reported clinical application in laparotomy for the system. We here report our commencing of the clinical application of the system to laparoscopic surgery and building a system fitted for laparoscope. Method: We conducted the clinical application to a case of laparoscopic hepato-biliary-pancreatic surgery.We conducted the operation using 3D super impose display. We examined the system's accuracy and usability. Result: In cases of deformation, anatomical deviation and fixed organ, the navigation was useful in comprehending blood vessels.We calculated its accuracy by FRE and average accuracy was 7.0mm. Even in the liver, we were able to set up various points by using a tool with a geometrical pattern . In addition, we developed the system so that we could repeatedly achieve registration in a short period. Conclusion: Although the laparoscopic navigation surgery has room to improve in registration method and accuracy, we discovered that there is a possibility of improving surgical efficiency by repeating registration and without the need to correspond to the change in target organs.
