Tu1141 FURTHER REFINEMENT OF A PREDICTIVE CALCULATION FOR THE SESSILE SERRATED POLYP DETECTION RATE

Sessile 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...

Sessile 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 ...

Inverted sessile serrated polyp diagnosed by magnifying image-enhanced colonoscopy.

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...

Sessile serrated adenoma/polyp leading to acute appendicitis with multiple pyogenic liver abscesses: A case report

INTRODUCTION Although appendicitis is a common disease, appendicitis concurrent with liver abscesses and sessile serrated adenoma/polyp (SSA/P) is rare. PRESENTATION OF CASE A 69-year-old man presented with symptoms of abdominal pain and fever. Computed tomography (CT) revealed multiple liver abscesses and an enlarged appendix with a pseudotumoral appearance, which suggested acute appendiciti...
