Adenoma detection rates (ADRs) are known to vary 4-fold to 10-fold within single gastroenterology groups. Possible contributors to this variability include differences in withdrawal time, washing-suction technique, and examination of the proximal sides of folds. Training is also important: The average rates of interval colon cancers after colonoscopy are consistently lower for gastroenterologists than for primary care physicians and surgeons.
Now, researchers have assessed the influence of visual gaze pattern (VGP) on ADRs. Using an eye-tracking device, the VGPs of 11 senior endoscopists were recorded as they watched three videos showing uncompressed high-definition segments from normal colonoscopy withdrawals. The image on the monitor was d…
