Position Changes During Colonosope Withdrawal Can Increase Adenoma Detection Rate

Researchers found position changes during colonoscope withdrawal can significantly increase polyp and adenoma detection rates, according to a study published in Gastrointestinal Endoscopy.

One-hundred thirty patients were studied during routine colonoscopy. The patients were examined either in the left lateral position followed by position changes or the left lateral position alone. The position changes were cecum to hepatic flexure, left lateral; transverse colon, supine; splenic flexure and descending colon, right lateral.

Results showed at least one adenoma was detected in 34 percent of patients that underwent a position change from the left lateral position, compared with 23 percent of patients who stayed in the left lateral position. Further, at least one polyp was found in 52 percent of patients who underwent a position change, compared to 34 percent of patients who stayed in the same position.
