PERSONAL COMMENTS:
Laparoscopic nephrectomy navigated with augmented reality is very useful to reduce estimated blood loss and to shorten operative time. We could avoid pancreatic injury by showing its position on submonitor. So less invasive operations could be possible to use our sophisticated augmented reality system in many different kinds of surgical fields.

ABSTRACT:
【Purpose】The key of successful laparoscopic nephrectomy is the treatment of renal vessels. So we investigated the efficacy of augmented reality in laparoscopic kidney resection in regard to blood loss, operative time and complications.
【Methods】In order for surgeons to navigate, 3-dimensional volume rendering images of renal vessels including their branches, pancreas, adrenal gland and tumor mass were created in advance of the operation based on results in computerized tomography examinations. Those images were augmented to surgical views on a sub-monitor which duplicated the main monitor images. A navigator adjusted the angles of the view and the size of volume of images from surgical views. The operators treated renal vessels using augmented reality images as a guide. Augmented reality navigation guided laparoscopic nephrectomy was performed on five cases with renal or ureteral cancer. We compared the data of navigation surgery using augmented reality with those without it.
【Results】Operative time ranged from 215 minutes to 360 minutes. Blood loss was below 50 ml in all cases, and no major complication was experienced. The comparison of surgeries with augmented reality or without it showed that operative time in augmented reality navigated surgery group was significantly shorter than in the one without augmented reality. There was no significant difference in blood loss between the two groups.
【Conclusions】Augmented reality made it possible to perform safe and bloodless surgery in laparoscopic nephrectomy.
