Value of orientation training in laparoscopic cholecystectomy

Area of Science:

• Surgical Education
• Medical Simulation
• Human Factors Engineering

Background:

• Disorientation in laparoscopic surgery, like cholecystectomy, increases patient morbidity and mortality.
• Developing expertise in laparoscopic procedures requires extensive operative experience.
• Novel training methods are needed to accelerate skill acquisition and improve patient safety.

Purpose of the Study:

• To evaluate the efficacy of teaching high-performance orientation strategies to novice surgical trainees.
• To determine if targeted training can improve performance and spatial awareness in laparoscopic cholecystectomy.
• To assess if this training can reduce the reliance on extensive operative experience for skill mastery.

Main Methods:

• A randomized controlled trial involving 30 medical students was conducted.
• Participants were allocated to either an orientation strategy tutorial group or a control group.
• Eye-tracking technology captured visual attention (gaze) during image-based orientation tasks.

Main Results:

• The intervention group demonstrated significantly higher correct orientation rates (75.6%) compared to the control group (56.1%).
• Visual behavior analysis revealed distinct differences in attention and strategy between groups.
• Trained novices' performance approached that of experienced surgeons (78.6%).

Conclusions:

• Novice training in orientation strategies markedly enhances laparoscopic cholecystectomy performance.
• Acquired skills can achieve proficiency levels comparable to experienced surgeons.
• This approach offers a potential pathway to expedite surgical skill development.
