Colonoscopy does not reduce right-sided advanced neoplasms
By Reuters Health
NEW YORK (Reuters Health), Dec 31 - Colonoscopy is more protective against advanced neoplasms in the left colon and rectum than in the right colon, results of a German study indicate. The findings were reported in the January 20 Journal of the National Cancer Institute.

Colorectal cancer screening participation is highest with immunochemical test
By Reuters Health
NEW YORK (Reuters Health), Dec 31 - More people participate in colorectal cancer screening with the immunochemical fecal occult blood test than with guaiac-based tests or sigmoidoscopy, Dutch researchers report in the January issue of Gut.

VC CAD aids experts in detecting intermediate polyps
By Eric Barnes
Computer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month.

Lesion size and morphology at VC good predictors of histology
By Eric Barnes
Size and morphology are good predictors of whether a colorectal lesion harbors advanced histology and needs to be removed, according to a new multicenter study from Italy. The results suggest that polyps of the same size detected at virtual colonoscopy could be classified and managed differently based on their morphology.

CAD catches most flat polyps on virtual colonoscopy
By Eric Barnes
Computer-aided detection (CAD) is sensitive for all but the flattest of flat colorectal lesions, even in minimally prepped patients, according to a new study from Italy. Using CAD, radiologists significantly improved their ability to detect the elusive polyps, which can harbor precancerous lesions.

Surveillance polyps show little growth at follow-up
By Eric Barnes
CHICAGO - A preliminary study from Italy adds weight to the argument that two- to three-year surveillance of 6- to 9-mm polyps doesn't unduly increase the risk of colorectal cancers. Diminutive polyps grow faster but present less cause for concern.

Wireless capsule endoscopy feasible in young children
By Reuters Health
NEW YORK (Reuters Health), Nov 11 - Wireless capsule endoscopy is feasible for detecting small intestinal pathology in children younger than 8 years old, according to a report in the November Gut. However, most children in this age group are unable to swallow the small device, so it needs to be introduced endoscopically.

Meta-analysis reveals paucity of advanced neoplasia in small polyps
By Eric Barnes
The prevalence of advanced neoplasia in subcentimeter polyps is extremely rare, according to a new meta-analysis of virtual colonoscopy data from more than 20,000 patients. As a result, the study authors believe that it's unnecessary to incur the costs and risks associated with resecting diminutive colorectal lesions detected at VC.

CAD fails to make up for inexperience in reading VC studies
By Erik L. Ridley
Using computer-aided detection (CAD) software with a 3D display technique can increase sensitivity for inexperienced readers of virtual colonoscopy exams, but it fails to narrow the performance gap with experienced interpreters, according to a study published in the October issue of Clinical Radiology.

VC excels at diverticulosis staging
By Eric Barnes
Although virtual colonoscopy practice has always focused on adenoma detection and colon cancer prevention, the exam is proving to be formidable in the staging of diverticular disease, a scourge of fast-food Western nations that affects most of their citizens by age 60.
