Normal Withdrawal Time Correlates With Polyp Detection Rate And Adenoma Detection Rate: A Quantitative Observational Study From A Metropolitan Australian Hospital

Colonoscopy is the gold standard bowel cancer screening test but it has reduced effectiveness for lowering colorectal cancer (CRC) rates due to the reported 20% missed detection rate for adenomas in a meta-analysis of tandem colonoscopy studies. The true missed detection rate for significant lesions is likely to be higher as these findings came from an era where the sessile serrated adenoma had not yet gained international consensus as a possible precancerous lesion.\n\nIn our retrospective observational …
