Virtual reality training in laparoscopic surgery: A systematic review & meta-analysis

Area of Science:

• Surgical Education
• Medical Simulation
• Virtual Reality Technology

Background:

• Laparoscopic surgery demands specialized skills distinct from open surgery.
• Training needs to occur outside the operating room due to reduced hours and patient safety concerns.
• Virtual reality (VR) simulation is an emerging tool for surgical skill acquisition.

Purpose of the Study:

• To systematically review and meta-analyze the effectiveness of VR simulation for laparoscopic abdominal surgery.
• To compare VR training against other simulation methods and no training.

Main Methods:

• Systematic literature search conducted until January 2014, adhering to PRISMA guidelines.
• Inclusion of randomized controlled trials comparing VR training with alternative methods or no training.
• Exclusion of studies lacking objective and validated assessment tools.

Main Results:

• Thirty-one randomized controlled trials were included in the meta-analysis.
• VR simulation demonstrated significantly greater effectiveness compared to video trainers.
• VR simulation was found to be at least as effective as box trainers.

Conclusions:

• Proficiency-based VR training, incorporating supervision, feedback, and haptic technology, is highly effective.
• Integration of VR training into surgical education curricula is now essential.
• Further research is needed to evaluate VR training's impact on patient outcomes and healthcare costs.
