Study: Longer Colonoscopy Withdrawal Times Associated With Higher Polyp, Adenoma Detection Rates

Share on Facebook
In a recent study published in The American Journal of Gastroenterology, researchers examine the link between withdrawal time in colonoscopy and increased polyp and adenoma detection.  

Researchers used data from the New Hampshire Colonoscopy Registry to analyze 7,996 colonoscopies performed in 7,972 patients by 42 endsocopists at 14 hospitals, ambulatory surgery centers and practices.

The researchers found that polyp and adenoma detection rates were highest with a nine-minute median withdrawal time. Detection of clinically significant serrated polyps was at its highest level at eight to nine minute median withdrawal time.

The researchers concluded that a nine-minute median withdrawal benchmark may improve colonoscopy quality.
