Because serrated lesions are the precursors of 20% to 30% of colorectal cancers, establishing a target serrated detection rate (SDR) for endoscopists has been suggested. To examine the correlation between the commonly used adenoma detection rate (ADR) and several different SDR measures, researchers analyzed data from a registry of patients aged ≥50 years undergoing 29,960 screening and 16,036 surveillance colonoscopies performed by 77 endoscopists.
The clinically significant serrated polyp detection rate (CSSDR) was based on detection of any sessile serrated adenoma/polyp (SSA/P), traditional serrated adenoma (TSA), or hyperplastic polyp (HP) ≥1 cm anywhere in the colon or any HP ≥5 mm and proximal to the sigmoid. The proximal serrated polyp…
