Computer-assisted colonoscopies reduce rate of missed lesions, study says 

Adenoma detection is significantly higher using computer-aided colonoscopy than high-definition white light colonoscopy, according to a new study from Clinical Gastroenterology and Hepatology.

The study tracked 223 patients who underwent both colonoscopy procedures. It is the first randomized trial in the U.S. examining the role of a computer-aided detection system during colonoscopy.

Here are three things to know:

1. Regular screening for adenomas reduces the risk of death from colon cancer by more than 60 percent. 

2. Adenoma detection rates and adenoma miss rates vary greatly across physicians — miss rates range from 6 percent to 41 percent.

3. For the group that underwent computer-aided colonoscopy first, the adenoma miss rate was just above 20 percent, significantly lower than the 34 percent miss rate among those who received standard, high-definition white light colonoscopy first.
