Colonoscopies get a lot easier thanks to technology

Turning 50 seems to come with its own set of  challenges, unlike any other age — be it mental, emotional or physical. It’s also when your doctor  is likely to start urging you to get a colonoscopy even if you do not have any symptoms.colonoscopy

But what used to be an unpleasant, albeit necessary and routine procedure, has now  become much less invasive, thanks to new technology. The “virtual colonoscopy” (or CT colonography)
is now an option for most people who can’t or don’t want to get a standard colonoscopy. It’s being embraced by many doctors and insurers nationwide.

Like its traditional counterpart, the virtual colonoscopy entails drinking a laxative 24 hours prior to the procedure. Unlike the traditional colonoscopy, which involves a long  camera-tipped tube, the virtual exam inserts only about a two-inch soft tube that sends small  puffs of gas to fill the colon so that a low-radiation dose computer-assisted CT or “CAT” scan can  produce two- and three-dimensional views of the colon. The entire procedure takes about 15 to 20 minutes, so you don’t need to be put to sleep and you can go right back to daily activities.

“It’s very good in screening, and the patient’s downtime is less,” Dr. Guy Barat, a radiologist at Community Hospital in New Port Richey, Florida, told the St. Petersburg Times in an interview.

Some diehard traditionalists opine that you still would need a traditional  colonoscopy to remove anything found by a virtual colonoscopy. However, the vast majority of exams  don’t find anything wrong, and the virtual test has been shown to dramatically increase screening rates. The virtual colonoscopy is an American Cancer Society-recommended screening exam. Even President Obama opted for a virtual colonoscopy over the standard test.

Experts say that the new technology can detect polyps the size of small blueberries, as well as cancer and other diseases. For the more than 140,000 Americans that are diagnosed with  colorectal cancer every year, with nearly 50,000 dying largely due to late detection, this screening is vital.

The exam has been FDA approved since 1995, and major insurer, now cover their members for virtual colonoscopies to screen for colon cancer. – NewsUSA
