High-def scopes have 97% polyps assessment accuracy, study finds

Gastroenterologists may not need to send colon polyps to a pathologist for examination as most physicians correctly evaluated whether a polyp was precancerous or benign using high-definition optical lenses during a colonoscopy, according to a study published in the December issue of Gastrointestinal Endoscopy.

The study was conducted by physician researchers at Jacksonville, Fla.-based Mayo Clinic. It included 522 patients, and the research team examined use of the Exera II 180 colonoscope and the Exera III 190 colonoscope to assess the polyps.


The study found that the physicians' assessment of polyps was 96 or 97 percent accurate. Investigators also found that physicians in the study had an extremely high adenoma detection rate using the scopes — 50 percent for the 180 model and 52 percent for the 190.
