To determine the value of this simulator in acquiring basic laparoscopic skills and to evaluate the correlation between the frequency of trials and performance.
Cross-sectional study.
Department of Obstetrics and Gynecology, University Hospital Schleswig-Holstein, Kiel, Germany.
PATIENT(S): Twenty-five in-training gynecological endoscopists and 15 medical students.
INTERVENTION(S): A demonstration of 10 laparoscopic skill tasks was shown to participants before administration of a pretest. Voluntary rounds of further trials were encouraged thereafter. The post-tests were administered 5 days later. Assessments were conducted by the same independent supervisor.
MAIN OUTCOME MEASURE(S): Improvements in overall scores and relative performance mean scores were compared using the independent t test. The comparison of various trial groups' mean was evaluated by one-way analysis of variance (ANOVA).
RESULT(S): There were significantly better post-test scores in all tasks for both groups compared to the pretest scores. There was no statistical difference between the overall relative training outcomes of both groups. There was a significant difference in group mean scores between the group of trainees who performed five or more rounds of trials and those who performed two to three trials.
CONCLUSION(S): The LTS3e simulator contributes to the acquisition of laparoscopic skills in less experienced surgeons. Performance improves progressively with practice.
确定该模拟器在获取基本腹腔镜技能方面的价值，并评估试验频率与操作表现之间的相关性。
横断面研究。
德国基尔市石勒苏益格 - 荷尔斯泰因大学医院妇产科。
25名在职妇科内镜医师和15名医学生。
在进行预测试之前，向参与者展示10项腹腔镜技能任务的演示。此后鼓励他们自愿进行更多轮次的试验。5天后进行后测试。评估由同一位独立监督员进行。
使用独立t检验比较总体得分和相对表现平均得分的改善情况。通过单因素方差分析（ANOVA）评估不同试验组均值的比较。
与预测试得分相比，两组在所有任务中的后测试得分均显著更高。两组的总体相对训练结果之间无统计学差异。进行了五轮或更多轮试验的受训者组与进行了两到三轮试验的受训者组之间的组均值存在显著差异。
LTS3e模拟器有助于经验不足的外科医生掌握腹腔镜技能。操作表现会随着练习而逐步提高。
