Intraoperative 3D Hologram Support With Mixed Reality Techniques in Liver Surgery.

Area of Science:

• Surgical Innovation
• Medical Imaging
• Mixed Reality Technology

Background:

• Traditional surgical support relies on sterile monitors.
• Enhanced spatial awareness and shared 3D visualization are crucial in complex surgeries.
• Current methods may lack real-time, intuitive anatomical representation.

Purpose of the Study:

• To investigate the potential of intraoperative 3D holograms using mixed reality in liver surgery.
• To evaluate the benefits of holographic displays for surgical support.
• To assess the role of this technology in complex hepatectomy procedures.

Main Methods:

• Preoperative computed tomography (CT) data was converted into 3D polygon models.
• These 3D models were displayed on head-mounted devices (HoloLens) in the operating room.
• Surgeons interacted with the holograms using gesture controls in a Wi-Fi-enabled environment.

Main Results:

• Surgeons successfully shared and manipulated a common 3D hologram without monitors.
• The hologram aided in visualizing tumor locations and dissection lines for multiple liver metastases.
• It facilitated a safe approach in a complex hepato-cellular carcinoma case with anatomical anomalies.

Conclusions:

• Intraoperative holograms with mixed reality serve as a valuable
• last-minute simulation
• tool, rather than for navigation.
• This technology offers improved spatial awareness, image sharing, and simplicity.
• Holographic displays represent a potential next-generation tool for surgical support.
