Laparoscopic suturing skills acquisition: a comparison between laparoscopy-exposed and laparoscopy-naive surgeons

Area of Science:

• Surgical Education
• Minimally Invasive Surgery

Background:

• Laparoscopic suturing is a complex surgical skill requiring extensive training.
• Mastery of laparoscopic techniques is crucial for effective minimally invasive surgery.

Purpose of the Study:

• To evaluate if prior laparoscopic surgery exposure accelerates the learning curve for laparoscopic suturing.
• To compare skill acquisition rates between laparoscopy-exposed and laparoscopy-naïve surgical trainees.

Main Methods:

• Twenty laparoscopy-exposed and 20 laparoscopy-naïve surgeons performed 5 laparoscopic gastrojejunostomies each on a porcine model.
• Performance was assessed by operation time, anastomotic score (leak, size, suture placement, mucosal approximation), and perceived difficulty.
• Baseline performance was compared to post-training performance.

Main Results:

• All surgeons demonstrated significant improvement in operation time, anastomotic score, and reduced difficulty.
• Initially, laparoscopy-exposed surgeons had faster operation times, but this difference diminished with training.
• No significant difference in overall anastomotic score was observed between groups by the end of training.

Conclusions:

• Surgical training effectively enhances laparoscopic suturing skills for both novice and experienced surgeons.
• Prior laparoscopic experience does not confer a lasting advantage in acquiring suturing skills, as novices achieve comparable proficiency.
• Laparoscopy-naïve surgeons successfully bridge the skill gap with dedicated training.
