Risk factors for XXXX from adenomatous polyps of the large bowel: a colonoscopic evaluation with histopathological correlation.

@entity1 @entity455 @entity1127 @entity548 @entity190 @entity5 @entity357 @entity652 @entity360 @entity1586
In 27 @entity1 with 74 @entity1586 we prospectively evaluated @entity1127 -related risk factors and specific histopathological characteristics that might result in @entity190 from these lesions. Each @entity1127 was endoscopically bathed in saline which was then aspirated back into a syringe through a catheter and tested for presence of blood on a @entity357 . Forty-nine @entity1127 were excised. We found the following: 1) A relatively small proportion of @entity652 (approximately 11%) have a propensity to bleed. 2) Approximately 22% of @entity1127 -bearing @entity1 have a @entity548 @entity652 . 3) Risk factors for @entity548 include @entity1127 size greater than 1.0 cm, presence of a stalk, and cherry-red color; associated histopathological findings include marked @entity455 and intramucosal lakes of blood. 4) Clinically detectable @entity548 occurs after @entity548 in the @entity1127 head and dissection of blood into the bowel lumen through the glandular or surface epithelium. Most @entity1127 are small, sessile and pink, without histopathological features of @entity548 and are unlikely to bleed. Therefore, @entity1 with Hemoccult-positive stools in whom such @entity5 are found should undergo further study to detect other causes of @entity360 . High-risk @entity1127 in otherwise asymptomatic @entity1 can be held responsible for @entity548 ; in them colonoscopic polypectomy with follow-up Hemoccult testing is sufficient management. Only if @entity548 persists is study of other parts of the gut essential.
