The purpose of this study was to validate the eoSim, an affordable and mobile inanimate laparoscopic simulator with instrument tracking capabilities, regarding face, content and construct validity on complex suturing tasks.
Participants recruited for this study were novices (no laparoscopic experience), target group for this training (surgical/gynaecologic/urologic residents, > 10 basic and < 20 advanced laparoscopic procedures) and experts (> 20 advanced laparoscopic procedures). Each participant performed the intracorporeal suturing exercise (Task 1), an upside down needle transfer (Task 2, developed for this study) and an anastomosis needle transfer (Task 3). Following, the participants completed a questionnaire regarding their demographics and opinion on the eoSim in terms of realism, didactic value and usability. Measured outcome parameters were time, distance, percentage of instrument tip off-screen, working area, speed, acceleration and smoothness.
In total, 104 participants completed the study, of which 60 novices, 31 residents and 13 experts. Face and content validity results showed a mean positive opinion on realism (3.9 Task 1, 3.6 Task 2 and 3.7 Task 3), didactic value (4.0, 3.4 and 3.7, respectively) and usability (4.2. 3.7 and 4.0, respectively). There were no significant differences in these outcomes between the specified expertise groups. Construct validity results showed significant differences between experts, target group or novices for Task 1 in terms of time (means 339, 607 and 1224 s, respectively, p < 0.001) and distance (means 8.1, 15.6 and 21.7 m, respectively, p < 0.001). Task 2 showed significant differences between groups regarding time (p < 0.001), distance (p 0.003), off-screen (p < 0.001) and working area (p < 0.001). Task 3 showed significant differences between groups, after subanalyses, on total number of stitches (p < 0.001), time per stitch (p < 0.001) and distance per stitch (p < 0.001).
The results of this study indicate that the eoSim is a potential meaningful and valuable simulator in the training of suturing tasks.
本研究旨在验证 eoSim 在复杂缝合任务方面的表面效度、内容效度和结构效度，eoSim 是一种具有器械跟踪功能的经济实惠且可移动的非活体腹腔镜模拟器。
本研究招募了新手（无腹腔镜经验）、目标受训人群（外科/妇科/泌尿科住院医师，>10 次基础腹腔镜手术和 <20 次高级腹腔镜手术）和专家（>20 次高级腹腔镜手术）作为参与者。每位参与者均进行了腔内缝合练习（任务 1）、颠倒的针转移（任务 2，为本研究开发）和吻合针转移（任务 3）。之后，参与者完成了一份关于他们人口统计学信息和对 eoSim 的看法的问卷，内容涉及模拟器的真实性、教学价值和可用性。测量的结果参数是时间、距离、器械尖端离屏百分比、工作区域、速度、加速度和流畅性。
共有 104 名参与者完成了这项研究，其中 60 名新手、31 名住院医师和 13 名专家。表面和内容效度的结果表明，参与者对真实性（任务 1 为 3.9、任务 2 为 3.6、任务 3 为 3.7）、教学价值（任务 1 为 4.0、任务 2 为 3.4、任务 3 为 3.7）和可用性（任务 1 为 4.2、任务 2 为 3.7、任务 3 为 4.0）的评价均为正面。在这些结果方面，指定的专业组之间没有显著差异。结构效度的结果表明，在任务 1 中，专家、目标受训人群和新手之间在时间（分别为 339、607 和 1224 秒，p<0.001）和距离（分别为 8.1、15.6 和 21.7 米，p<0.001）方面存在显著差异。在任务 2 中，各组在时间（p<0.001）、距离（p<0.001）、离屏（p<0.001）和工作区域（p<0.001）方面存在显著差异。在任务 3 中，经过亚分析，各组在总缝合针数（p<0.001）、每针缝合时间（p<0.001）和每针缝合距离（p<0.001）方面存在显著差异。
本研究结果表明，eoSim 是一种在缝合任务培训方面具有潜在意义和价值的模拟器。
