Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three-dimensional Imaging...

Area of Science:

• Gastroenterology
• Medical Imaging
• Surgical Technology

Background:

• Traditional two-dimensional (2D) gastrointestinal endoscopy suffers from a lack of depth perception, potentially leading to diagnostic inaccuracies.
• Existing endoscopic equipment can be utilized with a novel software-based three-dimensional (3D) system that converts 2D images to 3D.

Purpose of the Study:

• To evaluate a new software-based 3D endoscopy system designed to enhance depth perception and diagnostic accuracy.
• To compare the efficacy of 3D endoscopy versus traditional 2D endoscopy in simulated gastrointestinal snaring tasks.

Main Methods:

• A randomized comparative study involved 32 endoscopists performing snaring tasks under short- and long-distance conditions.
• Participants were allocated to either 2D or 3D imaging groups, with first-attempt success rates as the primary outcome measure.

Main Results:

• The 3D endoscopy group demonstrated a significantly higher first-attempt success rate in the long-distance scenario (53.13%) compared to the 2D group (21.88%, p=0.01).
• The 3D system notably improved depth perception and distance judgment, with benefits particularly observed in less experienced endoscopists.
• No significant difference in procedure time was found between the 2D and 3D imaging groups.

Conclusions:

• The novel 3D endoscopy software effectively enhances depth perception and distance judgment during gastrointestinal procedures.
• This technology offers significant advantages for improving procedural success rates, especially for endoscopists with less experience.
