Sessile serrated adenoma detection rate is correlated with adenoma detection rate
AIM To investigated the association between adenoma detection rate (ADR) and sessile serrated ADR (SSADR) and significant predictors for sessile serrated adenomas (SSA) detection. METHODS This study is a retrospective, single-center analysis. Total colonoscopies performed by the gastroenterologists at the University of Tokyo Hospital between January and December 2014 were retrospectively iden...
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 ...
متن کاملSessile serrated adenoma/polyps: Where are we at in 2016?
It is currently known that colorectal cancers (CRC) arise from 3 different pathways: the adenoma to carcinoma chromosomal instability pathway (50%-70%); the mutator "Lynch syndrome" route (3%-5%); and the serrated pathway (30%-35%). The World Health Organization has classified serrated polyps into three types of lesions: hyperplastic polyps (HP), sessile serrated adenomas/polyps (SSA/P) and tra...
متن کاملLoss of Expression and Promoter Methylation of SLIT2 Are Associated with Sessile Serrated Adenoma Formation
Serrated adenomas form a distinct subtype of colorectal pre-malignant lesions that may progress to malignancy along a different molecular pathway than the conventional adenoma-carcinoma pathway. Previous studies have hypothesised that BRAF mutation and promoter hypermethylation plays a role, but the evidence for this is not robust. We aimed to carry out a whole-genome loss of heterozygosity ana...
