Influence of XXXX age and colorectal polyp size on histopathology findings.

@entity1 @entity1127 @entity5 @entity189 @entity14 @entity652 @entity1141
BACKGROUND: @entity14 is a major cause of morbidity and mortality and can arise through the adenoma- @entity189 sequence. Colonoscopy is considered the method of choice for population-wide @entity5 screening. AIM: To assess the characteristics of endoscopically resected @entity1127 in a consecutive series of @entity1 who underwent colonoscopy at a university hospital and compare histopathology findings according to @entity1 age and polyp size. METHODS: Retrospective, cross-sectional of 1950 colonoscopy reports from consecutively examined @entity1 . The sample was restricted to reports that mentioned @entity1127 . A chart review was carried out for collection of demographic data and histopathology results. Data were compared for @entity1127 sized  <=0.5 cm and >= 0.6 cm and then for @entity1127 sized  <=1.0 cm and >= 1.1 cm. Finally, all @entity1127 resected from @entity1 aged 49 years or younger were compared with those resected from @entity1 aged 50 years or older. RESULTS: A total of 272 @entity1127 were resected in 224 of the 1950 colonoscopies included in the sample (11.5%). Polyps >1 cm tended to be pedunculated (p=0.000) and were more likely to exhibit an adenomatous component (p=0.001), a villous component (p=0.000), and @entity1141 (p=0.003). These findings held true when the size cutoff was set at 0.5 cm. @entity1 aged 50 years or older were more likely to have sessile @entity1127 (p=0.023) and @entity1127 located in the proximal colon (p=0.009). There were no significant differences between groups in histopathology or presence of @entity1141 . CONCLUSION: Polyp size is associated with presence of @entity652 , a villous component, and @entity1141 , whereas @entity1 age is more frequently associated with sessile @entity1127 in the proximal colon.
