The impact of training under different visual-spatial conditions on reverse-alignment laparoscopic skills development

Area of Science:

• Minimally Invasive Surgery
• Surgical Education
• Human Factors in Medicine

Background:

• Laparoscopic surgery can present visual-spatial challenges, such as 180° reverse-alignment, creating a mirror image of the operative field.
• Task performance is significantly impaired under reverse-alignment conditions, with impairment severity correlating with surgical experience.
• The study aimed to investigate the potential for developing reverse-alignment surgical skills through dedicated training.

Purpose of the Study:

• To determine if surgical skills for reverse-alignment laparoscopic procedures can be acquired through training.
• To assess the impact of specific training on adapting to sensorimotor discordance in a simulated surgical environment.

Main Methods:

• Twenty-two medical students were randomized into reverse-alignment or forward-alignment training groups.
• Participants completed a standardized laparoscopic peg transfer task in a video trainer over three 1-hour sessions within 8 weeks.
• Pre- and post-training performance was assessed under both forward and reverse-alignment conditions for all participants.

Main Results:

• Forward-trained subjects showed significant improvement in forward-alignment tasks but not in reverse-alignment tasks.
• Both groups improved under reverse-alignment conditions post-training, with notably dramatic improvements in the reverse-training group.
• This indicates that specific training is effective for adapting to reverse-alignment challenges.

Conclusions:

• Laparoscopic novices can successfully adapt to sensorimotor discordance using simulated training environments.
• While standard forward-training may offer some benefit, dedicated reverse-alignment training appears more beneficial for novice surgeons.
• Targeted training in reverse-alignment conditions can enhance surgical skills for managing extreme visual-spatial discordance.
