Optimizing resection of sessile serrated polyps.
Removal of precancerous lesions during colonoscopy reduces colorectal cancer (CRC) incidence and mortality [1]. Recent data have highlighted that interval CRC occurs despite previous colonoscopy. Incomplete removal of polyps is one of the factors leading to interval CRCs [2]. Incomplete polypectomy of sessile serrated polyps (SSPs) is four-fold higher than that of conventional adenomas [3] and ...
متن کاملProspective evaluation of the proportion of sessile serrated adenoma/polyps in endoscopically diagnosed colorectal polyps with hyperplastic features1
BACKGROUND AND STUDY AIMS Sessile serrated adenoma/polyps (SSA/Ps) are considered precursors of colorectal cancers with microsatellite instability. However, it is still difficult to differentiate SSA/Ps from hyperplastic polyps endoscopically; therefore, the prevalence of SSA/Ps remains uncertain in clinical practice. This study aimed to clarify the proportion of SSA/Ps in endoscopically diagno...
متن کاملMolecular characteristics of colorectal serrated polyps and hyperplastic polyps
The serrated neoplasia pathway of colorectal carcinogenesis is characterized by BRAF mutation and aberrant DNA methylation, which have not been reported on Korean patients. The aim of this study was to investigate BRAF mutation and DNA methylation in colorectal serrated polyps and the right colon.Between 2005 and 2013, 146 colon polyps (47 tubular adenomas [TAs], 53 traditional serrated adenoma...
متن کاملSessile serrated adenoma/polyps with a depressed surface: a rare form of sessile serrated adenoma/polyp
Sessile serrated adenoma/polyps (SSA/Ps) usually appear flat to sessile with a smooth-appearing surface. However, macroscopic appearances of SSA/P can vary from flat-elevated to nodular and can even show a pedunculated configuration as we previously reported. The aim of the current study was to evaluate the clinicopathologic features of another under-recognized form of SSA/P which shows a depre...
متن کاملSessile serrated lesion misdiagnosed as a hyperplastic polyp.
An 81-year-old woman presented for colonoscopy because of iron deficiency anemia. She had undergone colonoscopy 5 years previously during which a 2-cm prominent fold had been identified in the proximal ascending colon (●" Fig.1). A biopsy of this lesion was interpreted as being a hyperplastic polyp (●" Fig.2), although the polyp showed features of a serrated lesion. Because of clinical concern ...
