Abstract

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%, p = 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.

改善胃肠内窥镜操作人员的深度视觉：一种新型三维成像系统的初步研究

背景与目的传统的二维（2D）胃肠道内窥镜缺乏深度感知，导致潜在的诊断错误。本研究评估了一种新的基于软件的三维（3D）内窥镜系统，该系统可将2D图像转换为3D，与现有内窥镜兼容。方法对NTT医学中心32名内窥镜医师进行随机对照研究。参与者被分配在短距离和远距离场景中使用2D或3D成像来执行诱捕任务。比较了两组首次尝试的成功率。结果在远距离场景下，3D组首次尝试成功率（53.13%）明显高于2D组（21.88%,p = 0.01）。3D系统在深度感知和距离判断方面提供了显着改善，特别是对于经验不足的内窥镜医师。两组的每次尝试时间无显著差异。结论新的3D系统增强了深度感知和距离判断，特别有利于经验不足的内窥镜医师。
