New Technique Provides Microscopic Images of Suspicious Polyps During Colonoscopy

News from Digestive Disease Week 2008 A tiny microscope, less than one-sixteenth of an inch, attached to the end of the instrument used for a colonoscopy can provide magnified pictures of cells and small blood vessels in suspicious lesions allowing doctors to make on-the-spot decisions about whether a polyp is benign or precancerous. The technique — confocal endomicroscopy — can identify benign polyps 98 percent of the time, avoiding having to remove the lesion and wait for results of the biopsy.  Precancerous polyps can be viewed, identified, and treated immediately during the colonoscopy.

First Colonoscopy of the Day Finds More Polyps

The first colonoscopy performed each day finds more polyps — both small hyperplastic ones and more serious advanced adenomas.  As the day goes on, fewer polyps are found every hour. Researchers studied all the colonoscopies performed at the UCLA Veteran Administration Center in 2006 and 2007, keeping track of a number of variables that might affect the number of polyps found.  Even adjusting for patient differences, withdrawal times, and bowel preparation, the time of day remained a predictor of how many polyps were located during the colonoscopy.
