A significant number of sessile serrated XXXX might not be accurately diagnosed in daily practice.

@entity1 @entity652 @entity1127
BACKGROUND/AIMS: The diagnosis of @entity1127 ( @entity1127 ) may involve a conglomeration of subgroups of serrated @entity1127 . The diagnosis of @entity1127 may therefore be revisited if this is sessile serrated @entity652 (SSA). The aim of this study was to determine clinically and endoscopically relevant information associated with reclassification to SSA. METHODS: After reviewing the data from 1,372 @entity1 who underwent colonoscopic polypectomy, 49 @entity1127 larger than 10 mm were analyzed in this study. Two gastrointestinal pathologists reclassified each of the original 49 @entity1127 as conventional @entity1127 , SSAs, and others. RESULTS: Among the 49 initially diagnosed @entity1127 , 18.4% were reclassified into SSAs or mixed @entity1127 . Overall architectural features were useful for the diagnosis of SSA, but cytological features were less useful. The @entity1 and polyp characteristics did not differ between @entity1127 with and without reclassification of the initial pathological diagnosis. CONCLUSIONS: A significant number of SSAs might not be accurately diagnosed in daily clinical practice without any predilection for size, shape, and location. Therefore, when large @entity1127 are diagnosed in clinical practice, it is necessary for physicians to have greater awareness of the diagnosis of SSA and to individualize subsequent surveillance.
