Study shows that flat lesions are more likely to be missed during screenings

October 5, 2008

Have your patients been asking you about flat colon polyps? If they haven’t yet, it’s possible they soon will. A recent study published in the Journal of American Medical Association on the significance of flat colon polyps received significant coverage in major U.S. newspapers. The study, which came out of VA Palo Alto Health Care System, showed that flat polyps, also known as flat lesions, had a higher incidence of carcinoma than polypoid lesions.  And because these flat lesions tend to be smaller, they are more likely to be missed during screening.

Naturally, this type of report raises concerns among patients, but it also presents an opportunity to educate them on colorectal cancer. At Gastrointestinal Specialists of Georgia, we welcome the opportunity to assist you with this. Colorectal cancer is the third most commonly diagnosed cancer in the United States and the second leading cause of cancer deaths. Of the 150,000 people who are diagnosed with the disease each year, 10% will die. The good news is that early detection can reduce the chances of developing colorectal cancer. The bad news is that less than 50% of those of eligible age elect to undergo the screening.

When it comes to screening, the colonoscopy remains the gold standard for detecting colon polyps and flat lesions. Unlike other methods which can only diagnose a lesion, the colonoscopy is both therapeutic and diagnostic. A physician performing the colonoscopy can remove any lesions that are found. There are also important new colonoscopy guidelines, such as the optimal colon prep and adequate scope withdrawal time, that when followed have been shown to increase detection of these flat lesions.

At GI Specialists of Georgia, we adhere to the quality guidelines mentioned above.  We also offer the latest in diagnostic technologies, including Narrow Band Imaging, which uses blue light for better visualization of the intestine surface. Studies show that it does a better job of detecting polyps than traditional white light. We also perform high definition colonoscopies.

Our practice is the result of the 2007 merger of Northwest Georgia Gastroenterology Associates and Digestive Care Associates, so despite the new name we have a long history of serving the community of northwest Georgia. We offer open access screening for colonoscopies, which reduces the wait time for both patients and referring physicians. We welcome the opportunity to work with you and your patients in providing the highest levels of gastrointestinal care. If you have any questions or concerns, please don’t hesitate to contact us.
