Colon polyps, lesions better detected with HD endoscopy technology

High-definition, 3D endoscopes give doctors enhanced view during procedures.

Doctors are now using high-definition tools to better detect pre-cancerous lesions and colon polyps after a recent upgrade of endoscopy equipment at ADC’s outpatient surgery center.

The new state-of-the-art technology means doctors can see with twice the resolution with the endoscopes as they could before.

Dr. Todd Sheer, a gastroenterologist and hepatologist at ADC, says he’s been using the new equipment for only a few weeks, but already he has noticed a difference.

“It allows us to see the inside of the gastrointestinal tract with the same resolution that you could watch on your high definition television at home,” Dr. Sheer said. “Pretty much all parts of the [gastrointestinal] tract can be enhanced with this technology.”

Dr. Todd Sheer explains how the new HD endoscopes work.

ADC now has 10 of the high-definition endoscopes. With them they can see the:

  • Esophagus
  • Stomach
  • Small bowel
  • Large intestine

“We use it for upper endoscopy. It’s great for screening for pre-cancerous lesions of the esophagus and stomach,” Dr. Sheer said. “For colonoscopy, it helps us better detect colon polyps which can turn into cancer and to allow us to more efficiently remove them.”

Even some of the older instruments have been fitted with an enhanced processor so they can capture better images.

In addition to high quality images, the new endoscopes also give doctors a wider angle view of the gastrointestinal tract.

Doctors also use carbon dioxide during endoscopic procedures. Dr. Sheer says the carbon dioxide has been in use for years. It helps patients avoid feeling bloated and uncomfortable after an endoscopic procedure and speeds up recovery.

Dr. Sheer says he feels the new technology is the wave of the future.

    Where can I get the HD endoscopy? They can not find the polups in three colonoscopies and i’ve endured three diverticulitis events. Belleville,Il.
