Colonoscope retraction technique and predicting adenoma detection rate: a multicenter study

Targeting the low detector with artificial intelligence

“…First, a suboptimal coverage of the colorectal mucosa drives down the performance of the low detector as an unacceptable proportion of the inspection time is uselessly spent in visualizing the lumen of the colon rather than the surrounding mucosal surface. This is suggestively in line with a recent paper, correlating the movement of the colonoscope tip, as assessed by a scope-guide system, with the ADR [3]. Second, the association between withdrawal time and ADR can be explained, at least partially, by the fact that the decrease in withdrawal time is at the expense of adequate visualization of colorectal mucosa rather than speeding up its exploration.…”
