This study aimed to compare trainees' laparoscopic performance concerning the peg-transfer (PT) and needle-guidance (NG) exercises after watching the original European Basic Laparoscopic Urologic Skills (E-BLUS) video or after watching a video-mentored tutorial (VMT) with 'tips and tricks', narration and didactic illustrations.
An experimental, unblinded, parallel, 2-intervention, 2-period randomized trial with an allocation ratio of 1:1 was conducted. Forty-two participants were randomized into 2 groups. Prior to task initiation, Group 1 watched the VMT in both trials and Group 2 watched, firstly, the original E-BLUS examination video and, in the second trial, the VMT. Each participant performed 2 trials for each exercise. Outcome measures were task time and total number of errors.
In the first period, participants who visualized the PT and NG VMT had fewer errors than participants who visualized the E-BLUS video (p = 0.001 and p = 0.014, respectively). In the second period, after watching the VMT, a decrease in the total number of errors in PT and NG exercises was observed in the participants who previously watched the E-BLUS video (p = 0.001 and p = 0.002, respectively). In the second period, a decrease in median task time was observed for Group 1 and 2 after watching the PT VMT (p ≤0.001 and p = 0.003, respectively) and NG VMT (p = 0.005 and p = 0.01, respectively).
The use of VMT can lead to a smaller number of errors and, if coupled with deliberate practice, could lead to a shorter task time in exercise performance among participants with no previous laparoscopic experience.
本研究旨在比较学员在观看原始欧洲基础腹腔镜泌尿外科技能(E-BLUS)视频后,以及观看带有“技巧与窍门”、旁白和教学插图的视频指导教程(VMT)后,在钉转移(PT)和针引导(NG)练习方面的腹腔镜操作表现。
进行了一项实验性、非盲法、平行、双干预、两阶段随机试验,分配比例为1:1。42名参与者被随机分为两组。在任务开始前,第1组在两项试验中均观看VMT,第2组首先观看原始E-BLUS检查视频,在第二项试验中观看VMT。每位参与者对每项练习进行2次试验。结果测量指标为任务时间和总错误数。
在第一阶段,观看PT和NG VMT的参与者比观看E-BLUS视频的参与者错误更少(分别为p = 0.001和p = 0.014)。在第二阶段,观看VMT后,先前观看E-BLUS视频的参与者在PT和NG练习中的总错误数有所减少(分别为p = 0.001和p = 0.002)。在第二阶段,第1组和第2组在观看PT VMT后(分别为p≤0.001和p = 0.003)以及观看NG VMT后(分别为p = 0.005和p = 0.01),中位数任务时间均有所减少。
对于没有腹腔镜经验的参与者,使用VMT可减少错误数量,并且如果与刻意练习相结合,可缩短练习表现中的任务时间。
