Rectal bleeding often heralds serious colonic disease. The literature suggests that colonoscopy is superior to barium enema plus sigmoidoscopy, although no good comparative studies exist. Seventy one patients with overt rectal bleeding had prospectively flexible sigmoidoscopy, double contrast barium enema and colonoscopy completed independently. Against the gold standard, the sensitivity and sp...

OBJECTIVE To determine the time to benefit of using flexible sigmoidoscopy for colorectal cancer screening. DESIGN Survival meta-analysis. DATA SOURCES A Cochrane Collaboration systematic review published in 2013, Medline, and Cochrane Library databases. ELIGIBILITY CRITERIA Randomized controlled trials comparing screening flexible sigmoidoscopy with no screening. Trials with fewer than 1...

BACKGROUND Pediatric patients presenting with colitis, suggestive of inflammatory bowel disease, undergo evaluation with either flexible sigmoidoscopy or colonoscopy. Our objectives were to assess current practice behavior in the evaluation of pediatric patients with colitis and to determine whether flexible sigmoidoscopy or colonoscopy was more cost-effective as the initial evaluation. METHO...

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...

Background & AimsThe comparative effectiveness of sigmoidoscopy and fecal immunochemical testing (FIT) for colorectal cancer (CRC) screening is unknown.MethodsIndividuals aged 50–74 years living in Southeast Norway were randomly invited between 2012 2019 to either once-only flexible or FIT every second year. Colonoscopy was recommended after if any polyp ?10 mm, ?3 adenomas, advanced CRC found ...

BACKGROUND Employing colonoscopy, the gold standard in colorectal cancer (CRC) diagnosis testing, for CRC screening presents a significant risk of complications. Alternative methods with a lower invasive-level and fewer risks are proposed in combination, though each with lower diagnosis performance when applied separately. The main objective of this cross-sectional pilot study was to evaluate t...
