Learning curve of virtual chromoendoscopy for the prediction of hyperplastic and adenomatous colorectal lesions: a prospective 2-center study

ASGE Technology Committee systematic review and meta-analysis assessing the ASGE PIVI thresholds for adopting real-time endoscopic assessment of the histology of diminutive colorectal polyps

“…Studies indicate that accurate interpretation of optical biopsies follows a learning curve, and this learning curve can be achieved rapidly in both academic and community practice settings. [54][55][56][57][58][59] This ASGE Technology Committee systematic review and meta-analysis therefore confirms that the thresholds established by the ASGE PIVI for the real-time endoscopic assessment of the histology of diminutive polyps have been met, at least for NBI, with endoscopists who are experts in using these advanced imaging technologies and when assessments are made with high confidence. The ASGE Technology Committee therefore endorses the use of NBI for both the "diagnose-and-leave" strategy for diminutive rectosigmoid hyperplastic polyps and the "resect-and-discard" strategy for diminutive adenomatous polyps by endoscopists trained in using this technology for polyp characterization, making assessments with high confidence.…”

A prospective dual-center proof-of-principle study evaluating the incremental benefit of narrow-band imaging with a fixed zoom function in real-time prediction of polyp histology. Can we resect and discard?

“…Although studies have shown various training programs improves one's ability to recognize polyp characteristics with electronic chromoendoscopy, [30][31][32] it remains unknown how much training is required for someone to be qualified to use the NBI-NF with confidence. Different levels of training may be sufficient for practitioners to become adequate in recognizing polyp characteristics with confidence.…”

Preprocessing Endoscopic Images of Colorectal Polyps

“…Colorectal cancer is one of the most lethal health problem of our age [1]. Many studies pointed out that this disease is responsible for almost the highest cancer related mortality rate in Europe.…”
