背景小儿外科医生需要高度先进的微创手术技能，才能在非常脆弱的人群中进行罕见且复杂的手术。我们开发了新生儿食管闭锁（EA）模型来提高胸腔镜手术技能。本研究旨在通过使用 EA 模型和干燥箱 (DB) 对两组没有微创手术经验的学生进行培训前和培训后的技能评估来评估模型的并发有效性。方法进行了一项试点研究。参与者被随机分为两组：一组使用 DB 进行训练，一组使用 EA 模型进行训练。两组都练习了微创手术缝合任务。通过视频分析比较两组训练前后的任务完成时间、29分检查表评分、修正缝合错误表评分以及三维镊子移动情况。结果EA模型任务难度明显高于DB模型任务。两组在任务时间、29 分检查表评分和修改后的缝合错误表评分方面均显示出显着改善；然而，EA 模型训练在改善每个错误项方面更加有效。在镊子运动方面，EA模型训练显着减少了无用动作，而DB在这方面受到限制。 结论 EA模型比DB模型对技术要求更高，短期训练减少了技术错误和无用动作，并且使学习者比DB模型训练更有效地获得手术技能。这些事实揭示了 EA 模型的并发有效性。
BackgroundPediatric surgeons require highly advanced minimally invasive surgical skills to perform rare and complex surgeries in a very vulnerable population. We developed a neonatal esophageal atresia (EA) model to improve thoracoscopic surgical skills. This study aimed to evaluate the concurrent validity of the model by undertaking pre- and post-training skills assessments in two groups of students with no prior experience performing minimally invasive surgery, using the EA model and a dry box (DB).MethodsA pilot study was performed. The participants were randomly divided into two groups: one trained using the DB and one trained using the EA model. Both groups practiced a minimally invasive surgical suture task. The task completion time, 29-point checklist score, modified suturing error sheet score, and three-dimensional forceps movement in both groups were compared pre-and post-training by video analysis.ResultsThe EA model task was significantly more difficult than that of the DB. Both groups showed significant improvement in the task time, 29-point checklist score, and modified suturing error sheet score; however, the EA model training was more efficient in improving each error item. Regarding forceps movement, the EA model training significantly decreased wasted motion, whereas the DB was limited in this regard.ConclusionsShort-term training on the EA model, which was more technically demanding than the DB, decreased technical error and wasted motion, and allowed learners to acquire surgical skills more efficiently than training with the DB model. These facts revealed the concurrent validity of the EA model.
