The Varix Trainer model 1 (VTM1) was created for trainees to safely practice basic endoscope manipulation skills. The VTM1 was tested to see if it could distinguish levels of endoscope manipulation skills (construct validity) and whether training with it could improve these skills faster (content validity). We enrolled 23 novice endoscopists, 18 second-year trainees, and 13 expert endoscopists. They were asked to point with the endoscope tip to 20 numbers in the model as quickly as possible using torque, single-hand small/large wheel manipulation (SHSW), and retroflexion techniques. Their mean times (t20) were compared to determine if the model could distinguish different levels of expertise. Subsequently, 14 novices trained for eight short sessions, and the pre-training and post-training t20 were compared. Nine novice endoscopists received no training and were retested after 4 to 6 weeks (controls). Experts had faster t20 than second-year trainees, who were faster than novices, for all three techniques ( < 0.001). After eight sessions, the mean t20 for novices improved from 112 to 66 seconds for torque, 144 to 72 seconds for SHSW, and 108 to 63 seconds for retroflexion, (all < 0.001). Their t20 were equivalent to second-year trainees. Improvement in t20 was also seen with the control group, but total reduction was less than for the training group. The VTM1 distinguished varying levels of expertise for all techniques, suggesting that it is a valid tool for assessing endoscope manipulation skill. A short curriculum improved novices' manipulation skills faster than traditional practice.
静脉曲张训练器1型（VTM1）是为学员安全练习基本内镜操作技能而设计的。对VTM1进行了测试，以确定它是否能够区分内镜操作技能水平（结构效度），以及使用它进行训练是否能更快地提高这些技能（内容效度）。我们招募了23名新手内镜医师、18名二年级学员和13名专家内镜医师。要求他们使用扭矩、单手小/大轮操作（SHSW）和反转技术，尽快用内镜尖端指向模型中的20个数字。比较他们的平均时间（t20），以确定该模型是否能够区分不同水平的专业技能。随后，14名新手进行了8次短疗程训练，并比较了训练前和训练后的t20。9名新手内镜医师未接受训练，4至6周后重新进行测试（对照组）。对于所有三种技术，专家的t20比二年级学员快，二年级学员比新手快（<0.001）。8次疗程后，新手扭矩操作的平均t20从112秒提高到66秒，SHSW操作从144秒提高到72秒，反转操作从108秒提高到63秒（均<0.001）。他们的t20与二年级学员相当。对照组的t20也有改善，但总降幅小于训练组。VTM1能够区分所有技术的不同专业技能水平，表明它是评估内镜操作技能的有效工具。简短的课程比传统练习能更快地提高新手的操作技能。
