Core Tip

Core tip: Sessile serrated adenomas (SSAs) are difficult to detect and are associated with interval colorectal cancer (CRC). To reduce interval CRC and CRC death, SSA detection is important, and evaluation of the sessile serrated adenoma detection rate (SSADR) is crucial. In Western countries, there have been some reports showing the correlation of adenoma detection rate (ADR) and SSADR. However, in Asian countries, little is known about the correlation between ADR and SSADR. We investigated the association between ADR and SSADR and significant predictors for SSA detection in Japanese population. We found that ADR is correlated with SSADR, and patients with adenomas have a higher prevalence of SSAs than those without adenomas.
