BACKGROUND AND AIMS
Endoscopic suturing using a conventional suturing device has a steep learning curve. This study assesses the ease of use of a novel endoscopic suturing system compared to the conventional device using a validated simulator.
METHODS
This randomized, crossover study included suturing experts and novices performing pursestring suturing on a transoral outlet reduction simulator. Subjects were randomized to use the novel or conventional device first. Simulator scores and workload using National Aeronautical and Space Administration Task Load Index were recorded.
RESULTS
Ten subjects participated (4 experts, 6 novices). The novel device achieved higher simulator scores (179.3 ± 73.7 vs. 99.8 ± 94.1; P = 0.049) and lower workload (39.2 ± 15.9 vs. 70.5 ± 22.1; P = 0.002) than the conventional device. Novices demonstrated the greatest benefit.
CONCLUSION
This novel endoscopic suturing system improves ease of use and reduces workload, especially in endoscopists without prior suturing experience.
背景与目的
使用传统缝合设备进行内镜缝合具有陡峭的学习曲线。本研究使用经过验证的模拟器，评估一种新型内镜缝合系统与传统设备相比的易用性。
方法
这项随机交叉研究包括在经口出口缩小模拟器上进行荷包缝合的缝合专家和新手。受试者被随机分配首先使用新型或传统设备。记录使用美国国家航空航天局任务负荷指数的模拟器得分和工作量。
结果
10名受试者参与研究（4名专家，6名新手）。与传统设备相比，新型设备获得了更高的模拟器得分（179.3±73.7对99.8±94.1；P = 0.049）和更低的工作量（39.2±15.9对70.5±22.1；P = 0.002）。新手受益最大。
结论
这种新型内镜缝合系统提高了易用性并减少了工作量，特别是对于没有先前缝合经验的内镜医师。
