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.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
