Surveillance polyps show little growth at follow-up

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

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

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.

VC researchers weigh 3 iodine tagging regimens

A laxative-and-tagging regimen consisting of iodinated contrast plus a sodium phosphate mixture showed the best cleansing results among three concoctions in preparing for virtual colonoscopy exams. But a two-day regimen of iodinated contrast and a mild laxative at mealtime was better accepted by patients, according to a new study from Italy.

Advanced image processing stitches together CE images

An image processing technique forged in Japan could make wireless capsule endoscopy (CE) more useful by analyzing and cobbling together the somewhat unpredictable sequence of small intestine images generated by the tiny capsule endoscopy cameras.

Most choose VC over colonoscopy, study shows

A new study from the Netherlands has found that most patients preferred reduced-prep virtual colonoscopy over conventional optical colonoscopy. Patients judged reduced-prep VC, both prep and procedure, as less burdensome, a fact the researchers hope could lead to greater compliance in colorectal cancer screening.

Colorectal cancer attitudes vary by ethnicity

By Reuters Health

NEW YORK (Reuters Health), Aug 26 - Men and people of South Asian descent are more likely to have unfavorable perceptions of colon cancer screening, research from the U.K. shows. The findings point the way toward strategies to get more people screened, according to Dr. Taina Taskila, a researcher on the study.
