INFLUENCE OF MINIMALLY INVASIVE LAPAROSCOPIC EXPERIENCE SKILLS ON ROBOTIC SURGERY DEXTERITY.

Area of Science:

• Minimally Invasive Surgery
• Robotic Surgery
• Surgical Skill Acquisition

Background:

• The transition from traditional laparoscopic techniques to robotic surgery is not well understood regarding skill transfer.
• Investigating whether prior surgical experience influences robotic surgical performance is crucial for training programs.

Purpose of the Study:

• To assess and compare the performance and learning curves of basic robotic surgical tasks using a simulator.
• To evaluate individuals with diverse surgical backgrounds, including laparoscopic and open surgery experts, and non-medical subjects.

Main Methods:

• Three groups were evaluated: laparoscopic surgery experts (n=6), open surgery experts (n=6), and non-medical controls (n=4).
• Participants aged 40-50 years completed five repetitions of four simulated robotic tasks: spatial vision, bimanual coordination, hand-foot-eye coordination, and motor skill.

Main Results:

• Laparoscopic surgery experts demonstrated performance similar to non-medical subjects and superior to open surgery experts in three of the four tasks.
• All participant groups showed significant improvement in task performance with repeated practice, highlighting a general learning effect.

Conclusions:

• Laparoscopic surgical expertise correlates with better performance in basic robotic tasks compared to open surgery experts, though similar to novices.
• Open surgery experts exhibited the lowest performance levels in the simulated robotic tasks.
• Consistent improvement across all groups indicates that basic robotic skills can be learned and refined through practice.
