Monday, November 29 | 3:40 p.m.-3:50 p.m. | SSE08-05 | Room E450BIn this scientific session, researchers from the Mayo Clinic in Rochester, MN, will discuss the examination of more than 1,000 Medicare-aged patients with virtual colonoscopy. Their results showed the prevalence of polyps and extracolonic findings to be similar to those of younger populations.
The difference was that slightly more than half of the 1,042 Medicare-aged individuals were at increased risk from conventional colonoscopy, due to factors such as anticoagulation therapy (22%), prior incomplete colonoscopy (22%), or chronic obstructive pulmonary disease (COPD) or congestive heart failure (1.5%), according to presenter Lynn Wilson, Joel Fletcher, MD, and colleagues.
Evaluating 2,055 virtual colonoscopy (also known as CT colonography or CTC) exams in all, they found 5.4% of patients with polyps or cancers 1 cm or larger, 8.9% with only polyps 6-9 mm, and 6% of individuals with a clinically significant extracolonic finding that was previously unknown. There were no perforations.
Virtual colonoscopy is a useful adjunct to screening and diagnostic colonoscopy in the Medicare population, Wilson and colleagues concluded, particularly among patients with risk factors for complications at endoscopy.
