Comparison of 2D versus 3D in the Basic Single Incision Laparoscopy Training. A Randomized Controlled Trial

Area of Science:

• Minimally Invasive Surgery
• Surgical Education Technology
• Laparoscopic Techniques

Background:

• Single incision laparoscopic surgery (SILS) presents significant technical challenges for surgeons.
• Advanced visualization tools like 3D laparoscopy may enhance surgical training outcomes.
• Comparing 2D and 3D laparoscopy is crucial for optimizing novice training protocols.

Purpose of the Study:

• To evaluate the short-term efficacy of 3D versus 2D laparoscopy training for SILS.
• To compare skill acquisition and performance metrics between novice surgeons trained in 2D and 3D environments.

Main Methods:

• Forty surgical novices without prior SILS experience were recruited.
• Participants were randomly assigned to undergo training using either 2D or 3D laparoscopic systems.
• Performance was assessed through standardized tasks including polypropylene ball transfer, needle grasping, and intracorporeal knot tying.

Main Results:

• The 3D group completed the ball transfer task significantly faster (p=0.007).
• Novices in the 2D group made significantly more errors during the needle grasping task (p=0.033).
• The 3D training group showed a significantly higher probability of successfully completing intracorporeal knot tying (p=0.02).

Conclusions:

• 3D laparoscopy training appears to provide a distinct advantage over 2D for fundamental SILS skills.
• Enhanced depth perception and spatial understanding in 3D may contribute to improved surgical performance.
• 3D technology holds promise for accelerating proficiency in complex minimally invasive procedures.
