New models for advanced laparoscopic suturing: taking it to the next level

Area of Science:

• Surgical Education
• Minimally Invasive Surgery
• Medical Simulation

Background:

• Current laparoscopic suturing simulations lack real-world operating room complexity.
• A needs assessment identified critical training gaps in laparoscopic suturing skills.

Purpose of the Study:

• To develop three novel advanced laparoscopic suturing tasks with assessment metrics.
• To gather validity evidence for these new measures of suturing skill.

Main Methods:

• Three tasks were created: needle handling, suturing under tension, and continuous suturing.
• Minimally invasive surgeons and senior residents performed tasks; performance was rated on time and accuracy.
• Validity was assessed by comparing performance across experience levels; reliability and internal consistency were calculated.

Main Results:

• Minimally invasive surgeons outperformed senior residents on all tasks.
• All experienced surgeons completed tasks, while 33% of residents failed at least one.
• Suturing experience positively correlated with task performance (p < 0.01); high inter-rater reliability (0.99) and internal consistency (0.80) were found.

Conclusions:

• The developed advanced laparoscopic suturing tasks demonstrate validity evidence.
• Task performance correlates significantly with surgical training and experience.
• These tasks can enhance surgical curricula to improve resident suturing skills for operating room preparedness.
