Virtual reality applied to hepatic surgery simulation: the next revolution

Area of Science:

• Medical technology
• Surgical innovation
• Virtual reality applications

Background:

• Liver surgery presents significant challenges due to anatomical complexity and variability.
• Existing medical imaging tools lack specificity for detailed liver anatomy visualization.
• Improved comprehension of patient-specific liver structures is crucial for surgical planning.

Purpose of the Study:

• To explore the preliminary application of virtual reality (VR) in liver surgery.
• To discuss the impact of VR-assisted surgical strategies and simulation on future surgical practices.
• To address the limitations of current visualization tools for complex liver anatomy.

Main Methods:

• Development of a realistic 3D liver model using National Library of Medicine data.
• Creation of a computer interface for organ manipulation and resection plane definition.
• Implementation of initial surgical simulation with real-time deformation computation.

Main Results:

• Clear 3D visualization of liver anatomy, including internal structures and external envelope.
• Ability to manipulate the virtual liver and define resection planes based on anatomical relationships.
• Real-time simulation of liver deformation using virtual laparoscopic tools.

Conclusions:

• 3D VR visualization significantly aids in understanding complex liver anatomy and pathology.
• VR concepts (navigation, interaction, immersion) enable potential for surgical planning, training, and teaching.
• Repeated practice via simulation can revolutionize surgical training and improve intervention efficiency for optimal care.
