This multicenter randomized controlled trial tested whether real-time eye-tracking prompts to direct endoscopists’ gaze toward the screen periphery improved colorectal polyp detection. Across four institutions, 400 adults aged 40 to 90 years were enrolled; 198 were assigned to gaze guidance and 199 to control. Adenomas per colonoscopy were higher with guidance (1.34 vs 0.95; P = .046). Adenoma and polyp detection rates also improved, while observation time did not differ significantly. The findings suggest that peripheral-gaze prompts can increase detection without prolonging the procedure.
Key findings
- Adenomas per colonoscopy were 1.34 with gaze guidance versus 0.95 in controls (P = .046).
- Adenoma detection rate was 53.3% versus 39.2% (P = .007), and polyp detection rate was 66.5% versus 47.2% (P < .001).
- Peripheral gaze rate increased from 25.9% to 33.7% (P < .001); observation time was 8.4 versus 8.0 minutes (P = .094).
Why it matters
Adenoma detection is central to colonoscopy’s role in colorectal cancer prevention. This trial indicates that a visual-attention strategy, delivered through real-time feedback, may improve adenoma and polyp detection without a significant increase in observation time. It provides evidence that endoscopist gaze behavior is a potentially modifiable factor in detection performance.
What to keep in mind
The abstract does not report follow-up or outcomes beyond detection and observation time; the trial was conducted at four institutions.
