A Novel Three-Dimensional Stereoscopic Navigation System for Laparoscopic Anatomic Liver Resection

Area of Science:

• Surgical Technology
• Hepatobiliary Surgery
• Medical Imaging

Background:

• Stereoscopic 3D visualization with virtual reality offers intuitive spatial understanding compared to planar 3D images.
• 3D stereoscopic navigation systems are crucial for improving safety in liver resections by enabling precise tumor and blood vessel localization.
• A novel 3D stereoscopic navigation system provides real-time, multi-directional 3D simulation views for surgeons during procedures.

Purpose of the Study:

• To retrospectively analyze the surgical advantages of a novel 3D stereoscopic navigation system in laparoscopic anatomic liver resection (LALR).
• To evaluate the impact of the 3D stereoscopic navigation system on perioperative surgical outcomes and accuracy in LALR.

Main Methods:

• Forty-four patients undergoing LALR were divided into two groups (n=22 each): one with and one without the 3D stereoscopic navigation system.
• Perioperative surgical results and accuracy of excised liver volume were compared between the two groups.
• Patient characteristics were analyzed to ensure comparability between the groups.

Main Results:

• No significant differences in patient characteristics were observed between the groups.
• The group utilizing the 3D stereoscopic navigation system demonstrated significantly lower estimated blood loss (118 mL vs. 218 mL, p = 0.048).
• No other significant differences in surgical outcomes were found between the groups.

Conclusions:

• The novel 3D stereoscopic navigation system effectively reduces intraoperative blood loss during LALR.
• This system enhances precise anatomical identification, contributing to improved surgical outcomes in laparoscopic liver resections.
