Construct Validity of the Avian Model for Neonatal Laparoscopic Surgery Training.

Area of Science:

• Surgical Education
• Medical Simulation
• Minimally Invasive Surgery (MIS)

Background:

• Neonatal laparoscopic surgery requires specialized training.
• Realistic and cost-effective simulators are crucial for skill development.
• The avian model offers a novel approach to surgical simulation.

Purpose of the Study:

• To validate the construct validity of an avian model for neonatal laparoscopic surgery training.
• To assess the avian model's effectiveness in differentiating surgical skill levels.
• To establish the avian model as a reliable platform for pediatric MIS training.

Main Methods:

• Thirteen participants (novices, residents, seniors) performed laparoscopic suturing tasks on the avian model.
• Performance was evaluated using a modified Objective Structured Assessment of Technical Skills (OSATS) framework.
• Data analysis focused on specific and general skill scores and execution time.

Main Results:

• The avian model significantly distinguished between skill levels (P=0.024 for specific, P=0.016 for general scores).
• Surgical skill scores improved with experience, and execution time decreased accordingly (P=0.019).
• High interobserver agreement (κ=0.87, κ=0.84) and superior performance by seniors were observed.

Conclusions:

• The avian model demonstrates strong construct validity for surgical simulation.
• It is an effective tool for differentiating surgical skill levels in pediatric MIS.
• The avian model provides a reliable and reproducible platform for surgical training.
