To determine whether veterinary students could train to a predefined proficiency level on a simulated intracorporeal laparoscopic suturing task.
Single group preinterventional and postinterventional study.
Ten veterinary students.
Ten veterinary students completed a questionnaire about prior experiences and watched a 7-minute demonstration video prior to performing a laparoscopic intracorporeal suture task on a simulator. Participants were tested at pretraining and for a period of 8 weeks. Overall group improvement in scores and time to completion (seconds) from pretraining to final testing was analyzed by using a Wilcoxon matched-pairs signed-rank test. The same variables were compared among individuals with different background experiences (eg, video game experience) by using a Mann-Whitney U test. The average number of repetitions to reach proficiency was recorded.
All participants reached the predefined proficiency level on the Fundamentals of Laparoscopic Surgery intracorporeal suture task. The average number of repetitions required to reach proficiency was 18 ± 7, and there was significant improvement in both time to completion (seconds) and scores from pretraining to final testing (P = .005). The number of repetitions required to reach proficiency, pretraining times, final times, pretraining scores, and final scores did not differ among veterinary students with different background experiences.
Veterinary students naïve to laparoscopic surgery can learn the technical skills required to perform a simulated intracorporeal suture through repetitive, self-directed practice on a laparoscopic box trainer regardless of prior experiences (eg, videogame experience, craft experience, chopstick use, etc).
Simulation offers an adequate platform for the standardized training of laparoscopic skills in veterinary students and likely novice laparoscopic surgeons.
确定兽医专业学生能否通过训练在模拟体内腹腔镜缝合任务中达到预先设定的熟练水平。
单组干预前和干预后研究。
10名兽医专业学生。
10名兽医专业学生在模拟器上进行腹腔镜体内缝合任务前，完成一份关于既往经历的问卷并观看一段7分钟的演示视频。参与者在训练前及为期8周的时间内接受测试。采用Wilcoxon配对符号秩检验分析从训练前到最终测试时总体组在得分和完成时间（秒）方面的改善情况。使用Mann-Whitney U检验比较具有不同背景经历（如电子游戏经历）的个体之间的相同变量。记录达到熟练水平所需的平均重复次数。
所有参与者在腹腔镜手术基础体内缝合任务中均达到了预先设定的熟练水平。达到熟练水平所需的平均重复次数为18±7次，从训练前到最终测试，完成时间（秒）和得分均有显著改善（P = 0.005）。不同背景经历的兽医专业学生在达到熟练水平所需的重复次数、训练前时间、最终时间、训练前得分和最终得分方面没有差异。
对腹腔镜手术毫无经验的兽医专业学生，无论其既往经历（如电子游戏经历、手工经历、使用筷子等）如何，都可以通过在腹腔镜训练箱上进行重复的自主练习，学会执行模拟体内缝合所需的技术技能。
模拟为兽医专业学生以及可能的腹腔镜手术新手提供了一个标准化腹腔镜技能训练的合适平台。
