Study: Optical Colonoscopy More Effective Than CT Colonography

Although medical literature has shown computerized tomographic colonography and optical colonoscopy are both effective at detecting advanced adenomas, recent research indicates optical colonoscopy programs are significantly more effective at detecting non-advanced adenomas, according to an article published in American Journal of Gastroenterology.

Researchers assessed 1,700 optical colonoscopy examinations and 1,307 CT colonography examinations and found 23.2 percent of patients in the optical colonoscopy group had at least one adenoma removed, while 5.9 percent of patients in the CT colonography group had at least one adenoma removed. Optical colonoscopy also resulted in significantly higher detection of adenomas than CT colonography. However, the number of advanced lesions detected between the two groups was not significant.

Researchers conclude than an optical colonoscopy program is significantly more effective at detected non-advanced adenomas, with the primary difference between the two modalities being recovery and management of subcentimeter adenomas.
