General & GI surgery: Does VR surgical planning improve patient outcomes?

“No AR-related complications occurred.”

“There was a significant difference in the mean intraoperative bleeding volume between the two groups, but it was reduced in the MR group.”

“Compared with the MR (-) group, intraoperative blood loss and hospital stay were decreased, and the number of lymph nodes harvested around the middle colic artery/vein were increased without prolonging the operative time in the MR (+) group.”

“The application of AR technology facilitated precise tumor localization, reduced the operation time, and prevented damage to vessels and adjacent anatomical structures.”

“The tumor location was confirmed close to the liver, and a feeding artery and vein were identified from the forward and retroflexed views ( Fig. 3 , Fig. 4 a,b ). gEFTR ( Video 1 ) was then completed safely, with no bleeding.”

“The procedure incorporated VR for navigation and ICG fluorescence for real-time vascular mapping, facilitating precise dissection and preservation of critical structures.”

“Novel techniques, including ultrasonography-guided placement of a guiding marker and strategic port-site placement facilitated by HoloLens2, ensured accurate tumor identification and laparoscopic resection with minimal blood loss and no intraoperative complications.”

“EFTR was safely completed without any intraoperative adverse events ( Video 1 ).”

“Both techniques were used (8 clinical cases) for preoperative planning and intraoperative navigation, which allowed surgeons to verify the radicality of the operation, to have visual control of all anatomical structures near the zone of interest”
