Abstract

Purpose: To validate the construct validity of the avian model, a cost-effective and realistic simulator using chicken cadavers for neonatal laparoscopic surgery training.

Methods: Thirteen participants with varying experience levels (novices, residents, and seniors) performed laparoscopic suturing tasks on the avian model during a pediatric MIS course in Geneva. Performance was evaluated using a modified OSATS framework (specific and general scores).

Results: The avian model significantly distinguished between skill levels: specific ( P =0.024) and general ( P =0.016) scores improved with experience. Execution time decreased accordingly ( P =0.019). Interobserver agreement was high (κ=0.87, κ=0.84). Seniors outperformed novices and residents in all metrics.

Conclusion: The avian model demonstrates strong construct validity and is effective in differentiating surgical skill levels. It offers a reliable, reproducible platform for pediatric laparoscopic training.

构建新生儿腹腔镜手术训练的Avian模型的有效性。

目的：验证鸡尸体模型构建的有效性，为新生儿腹腔镜手术训练提供一种具有成本效益和真实感的模拟器。方法：在日内瓦儿科MIS课程期间，13名不同经验水平的参与者（新手、住院医师和老年人）在鸟类模型上执行腹腔镜缝合任务。使用改进的OSATS框架（具体分数和一般分数）评估绩效。结果：鸟类模型在技能水平上有显著的差异，具体得分（P=0.024）和一般得分（P=0.016）随经验的增加而提高。执行时间相应减少（P=0.019）。观察者间一致性高（κ=0.87, κ=0.84）。老年人在所有指标上都优于新手和住院医生。结论：该模型具有较强的构造效度，能有效地区分手术技术水平。它为儿科腹腔镜培训提供了一个可靠的、可重复的平台。
