Face, content, and construct validity of a novel portable ergonomic simulator for basic laparoscopic skills

Area of Science:

• Surgical Education
• Medical Simulation
• Laparoscopic Surgery

Background:

• Laparoscopic simulation is crucial for improving surgical skills.
• Assessing the validity of new simulation tools is essential for effective training.

Purpose of the Study:

• To validate the face, content, and construct validity of the Ergonomic Laparoscopic Skills simulator (Ergo-Lap simulator).
• To evaluate the Ergo-Lap simulator's effectiveness in assessing basic laparoscopic skills.

Main Methods:

• Four tasks were used: translocation (basic and single-handed), tissue manipulation, and needle handling.
• Performance was measured by speed and accuracy; usability and didactic value were rated on a Likert scale.
• Forty-six surgical residents (26 novice, 20 experienced) participated.

Main Results:

• Experienced surgeons were significantly faster and more accurate than novices on most tasks (p < 0.001).
• 96% of novices and 95% of experienced participants found the Ergo-Lap simulator useful for practice and skill development.
• The simulator was rated as easy to use and ergonomically beneficial.

Conclusions:

• The Ergo-Lap simulator is a valid and useful tool for laparoscopic skills training.
• It effectively differentiates between varying levels of surgical expertise.
• It offers an affordable and accessible option for surgical trainees to practice skills anywhere.
