Using risk for advanced proximal colonic neoplasia to tailor endoscopic screening for colorectal cancer.
BACKGROUND Colonoscopic screening for colorectal cancer has been suggested because sigmoidoscopy misses nearly half of persons with advanced proximal neoplasia. OBJECTIVE To create a clinical index to stratify risk for advanced proximal neoplasia and to identify a subgroup with very low risk in which screening sigmoidoscopy alone might suffice. DESIGN Cross-sectional study. SETTING A comp...

susceptibility by reductive metabolism gene variants. Sigmoidoscopy may reduce the incidence and mortality of colo-rectal cancer (CRC) in two ways. The first is by direct detection of distal (left-sided) early-stage CRC and removal of precancer-ous adenomatous polyps. The second takes advantage of the association between distal neoplastic findings and advanced neoplasia in the proximal colon. S...
متن کاملDiagnostic value of distal colonic polyps for prediction of advanced proximal neoplasia in an average-risk population undergoing screening colonoscopy.
BACKGROUND For colorectal cancer screening, the predictive value of distal findings in the ascertainment of proximal lesions is not fully established. The aims of this study were to assess distal findings as predictors of advanced proximal neoplasia and to compare the predictive value of endoscopy alone vs. combined endoscopic and histopathologic data. METHODS Primary colonoscopy screening wa...
متن کاملPatient satisfaction with screening flexible sigmoidoscopy.
BACKGROUND Screening flexible sigmoidoscopy is an underused cancer prevention procedure. Physicians often cite patient discomfort as a reason for not requesting sigmoidoscopy, but patient experiences and attitudes toward sigmoidoscopy have not been well studied. OBJECTIVE To measure patient satisfaction and the determinants of satisfaction with screening sigmoidoscopy. METHODS An instrument...
متن کاملFlexible sigmoidoscopy in outpatients with suspected colonic disease.
One hundred and fifteen patients attending a gastroenterology clinic were investigated by flexible sigmoidoscopy as outpatients. There were asked to fast before the examination and give a high-volume enema and sedated before the examination. A standard long colonoscope was used rather than the 60-cm sigmoidoscope, which limits the distance that can be examined and forces the operator to work ve...
