Randomized trial demonstrates enhanced preoperative accuracy in laparoscopic surgery using augmented reality, suggesting improved surgical outcomes.

To apply an augmented reality system for projecting 3D models from CT scans to enhance preoperative planning in laparoscopic surgery.
Used contrast-enhanced computed tomography scans for anatomical segmentation.
Manually defined regions of interest using OsiriX software to create 3D models.
Developed an augmented reality application with Unity for visualization on Meta Quest 3 glasses.
Anatomical models enabled accurate identification of tumors and their relation to critical structures.
Gesture-based manipulation of 3D models facilitated interaction during planning.
Limitation noted in anatomical accuracy requiring reference points for precise projection alignment.

Trebolle et al. (2026) studied this question.
