Laparoscopic suturing learning curve in an open versus closed box trainer.

Area of Science:

• Minimally Invasive Surgery
• Surgical Education
• Laparoscopic Skills Training

Background:

• Assessing the impact of direct vision training before indirect vision training on laparoscopic suturing.
• Evaluating the learning curve for novice laparoscopic surgeons.

Purpose of the Study:

• To determine if initial training with direct vision enhances laparoscopic suturing skill acquisition.
• To compare the efficiency and user experience of different laparoscopic training approaches.

Main Methods:

• Randomized novice groups: Group 1 (direct vision then indirect vision), Group 2 (indirect vision only).
• Measured performance time, motion economy, and tissue handling forces.
• Assessed self-perceived dexterity, frustration, and perceived difficulty via questionnaire.

Main Results:

• Group 1 completed tasks 27% faster than Group 2.
• No significant differences in motion or force parameters were observed between groups.
• Group 2 reported lower post-training dexterity and higher frustration levels.

Conclusions:

• Starting laparoscopic skill training with direct vision in a transparent box trainer is beneficial for novices.
• This approach reduces task completion time and frustration while achieving comparable skill outcomes.
• Direct vision initial training improves the overall learning experience for complex laparoscopic procedures.
