The model changed the attention workflow rather than the clinical decision right; value came from watching every frame without slowing the procedure.
AI value · Adenomas detected per colonoscopy
Verified
1.07 in the CADe group; incidence-rate ratio 1.46, with no increase in withdrawal time
Randomized detection endpoint; the trial did not establish reduced colorectal-cancer mortality, and much of the uplift was in small lesions.
Before
Inspect the live colonoscopy feed and visually identify suspected lesions. → Determine whether removed tissue is neoplastic.
After
Processes the live video and superimposes a green box over a suspected lesion. → Inspects the highlighted area and decides whether to remove tissue.
Human boundary
The AI draws attention; the endoscopist decides whether a finding is real and whether to resect.
Why it matters
That the endoscopist must be the only visual observer capable of flagging a lesion during withdrawal.

Exception path
The physician ignores false alerts, inspects missed or ambiguous tissue directly, and relies on histopathology for final classification.
Decision authority
The AI draws attention; the endoscopist decides whether a finding is real and whether to resect.

Work that left the path
Reliance on one unaided visual observer for every frame
Human role before
The endoscopist acted as the sole real-time visual detector.
Human role after
The endoscopist remains the procedural decision maker but works with an always-on secondary observer.
AI role
Deep-learning computer vision that flags suspected colorectal lesions on the live display.
Outcomes
Adenomas detected per colonoscopy
Verified
0.71 mean adenomas per colonoscopy in the standard-colonoscopy control group→1.07 in the CADe group; incidence-rate ratio 1.46, with no increase in withdrawal time
September-November 2019 randomized trial · 685 subjects at three Italian centers
Randomized detection endpoint; the trial did not establish reduced colorectal-cancer mortality, and much of the uplift was in small lesions.
What leaders can reuse
Anti-pattern
Calling every AI box a diagnosis or extrapolating detection uplift to mortality.
