The Differences In Adenoma Detection Rates And The Numbers Of Adenomas Per Colonoscopy In Fit-Based Colonoscopy Vs. Primary Screening Colonoscopy: A Multi-Center Study In Thailand

The adenoma detection rate (ADR) is one of the quality metrics in screening colonoscopy. Without other primary screening methods, ADR >25% is recommended. Recently, the number of adenomas detection per total colonoscopy (APC) (0.5 for men and 0.2 for women) has been purposed as another benchmark for quality metrics. In many countries especially limited resource, fecal immunochemical test (FIT) has been used as the primary screening method. Hypothetically, positive FIT colonoscopy may increase the detection rate of adenoma and the differences in ADRs and APCs in FIT-positive and FIT-negative colonoscopies have never been explored.
