WHICH LESIONS ARE AT HIGHER RISK OF DEVELOPING COLORECTAL CARCINOMAS: SUPERFICIALLY ELEVATED SERRATED LESIONS OR DEPRESSED LESIONS?

There are lesions that are still being missed in colonoscopy. Many of those could be superficially elevated serrated lesions or depressed ones. The aim of this study was to compare the histopathological characteristics of these lesions and their risks for submucosal carcinoma. This is a retrospectiv...

Zusammenfassung:	There are lesions that are still being missed in colonoscopy. Many of those could be superficially elevated serrated lesions or depressed ones. The aim of this study was to compare the histopathological characteristics of these lesions and their risks for submucosal carcinoma. This is a retrospective, cross-sectional, and observational study comparing 217 superficially elevated serrated lesions larger than 5 mm resected by colonoscopies (G1) with 558 depressed lesions (G2). In G1, 217 lesions were found in 12,653 (1.7%) colonoscopies; in G2, 558 lesions were found in 36,174 (1.5%) colonoscopies. In G1, 63.4% were women and in G2, there was no gender predominance. The average size of G1 was 16.2 mm and G2 was 9.2 mm (p
