BACKGROUND Simulation in laparoscopic surgery is nowadays recognized as a valid instrument for learning and training surgeons in different procedures. However, its role as evaluation test and self-assessment tool to verify basic surgical skills is still under discussion. METHODS Thirty-three residents in obstetrics and gynecology at University of Pisa, Italy were recruited, and they received a simulation program consisting of 5 tasks. They had to perform basic laparoscopic surgery maneuvers as creating pneumoperitoneum, positioning trocars under vision, demonstrating the appropriate use of dominant and non-dominant hand and making single stitch and knot. They were evaluated with a modified OSATs scale. RESULTS Senior trainees had better score than junior trainees (p value< 0,005) and after different sessions of simulation scores of both groups significantly improved (p < 0,001), especially for the junior group. All the trainees reported self-assessments that matched with the evaluation of external observers demonstrating the importance of simulation also as auto-evaluation test. CONCLUSIONS In this study, we demonstrated the role of simulation as powerful tool to evaluate and to self-assess surgical technical skills and to improve own capacities, with the use of a modified OSATs scale adapted to specific exercises.

模拟作为评估和提高腹腔镜妇科手术技术技能的工具。

背景技术如今，腹腔镜手术中的模拟被认为是在不同手术中学习和培训外科医生的有效工具。然而，其作为验证基本手术技能的评估测试和自我评估工具的作用仍在讨论中。方法招募33名意大利比萨大学妇产科住院医师，接受由5个任务组成的模拟程序。他们必须执行基本的腹腔镜手术操作，如产生气腹、在视野下定位套管针、演示惯用手和非惯用手的正确使用以及制作单针和打结。他们使用修改后的 OSAT 量表进行评估。结果 高级学员的分数高于初级学员（p 值 < 0,005），并且经过不同的模拟训练后，两组的分数均显着提高（p < 0,001），尤其是初级组。所有学员都报告了与外部观察员的评估相匹配的自我评估，证明了模拟作为自我评估测试的重要性。结论 在这项研究中，我们通过使用适合特定练习的修改后的 OSAT 量表，展示了模拟作为评估和自我评估外科技术技能以及提高自身能力的强大工具的作用。
