Abstract
Patients undergoing screening colonoscopies from January 2011 to September 2012 in whom colonic polyps were found were prospectively included in our study Polyp morphology location polyp pit pattern Kudo classification and other previously reported features of SSA were evaluated Histological examination was conducted independently by two pathologists Multivariate analysis was performed to identify independent predictors of SSAA total of 272 patients were included and 440 polyps were evaluated 16 polyps per patient Thirtyfour polyps 8 were SSA 135 31 hyperplastic and 249 56 adenomas The most prevalent endoscopic features of SSA were rightside location 94 type II Kudo pit pattern 91 mucus cap 41 flat morphology 29 and redcolored surface 26 Multivariate analysis revealed that flat morphology p = 0002 OR = 381 CI 153–909 redcolored surface p 0001 OR = 1297 CI 443–3769 rightside location p 0001 OR = 2221 CI 509–13594 and mucus cap p 0001 OR 877 CI 376–2044 were independent predictors of SSA
