BACKGROUND AND AIMS
Traditional two-dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software-based three-dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes.
METHODS
A randomized comparative study was conducted with 32 endoscopists at NTT Medical Center. Participants were assigned to perform snaring tasks using either 2D or 3D imaging in short- and long-distance scenarios. Success rates in first attempts were compared between the two groups.
RESULTS
In the long-distance scenario, the first-attempt success rate was significantly higher in the 3D group (53.13%) compared to the 2D group (21.88%, = 0.01). The 3D system provided a notable improvement in depth perception and distance judgment, especially for less experienced endoscopists. No significant difference was observed in the time per attempt between the two groups.
CONCLUSIONS
The new 3D system enhances depth perception and distance judgment, particularly benefiting less experienced endoscopists.
背景与目的
传统的二维胃肠内窥镜检查缺乏深度感知，可能导致诊断错误。本研究评估了一种新型的基于软件的三维内窥镜系统，该系统可将二维图像转换为三维图像，与现有内窥镜兼容。
方法
在NTT医疗中心对32位内镜医师进行了一项随机对照研究。参与者被分配在近距离和远距离场景中使用二维或三维成像执行圈套任务。比较两组首次尝试的成功率。
结果
在远距离场景中，三维组的首次尝试成功率（53.13%）显著高于二维组（21.88%，P = 0.01）。三维系统在深度感知和距离判断方面有显著改善，尤其是对于经验较少的内镜医师。两组之间每次尝试的时间没有显著差异。
结论
新的三维系统增强了深度感知和距离判断，尤其使经验较少的内镜医师受益。
