The focus of our study was to define a structured classification of false-positive (FP) results provided by the Artificial Intelligence CADe system that was recently applied in endoscopic daily practice and to estimate their absolute and relative frequency, as well as their clinical relevance in a real-life scenario.
Artificial intelligence represents one of the most revolutionary turning points in the endoscopic daily practice. This CADe system is based on deep learning in which the computer learns to extend the provided algorithms and to create new ones without any human control. Thus, its outcome incorporates some unpredictability in the clinical setting that may hamper the efficiency of CADe-colonoscopy as a matter of additional time required to discriminate between actual false positives and true lesions as well as carrying a risk for unneeded resection.
Our study reported a high frequency of false-positive results (27.3 ± 13.1 per colonoscopy) not correlated to any clinical relevance in which no unneeded resections were performed and false-positive results observation only represented 0.7% of the mean withdrawal time. In the near future, we expect these CADe systems to improve even more in their specificity.
