Polyp miss rates high for colonoscopies done after poor bowel preparation

A new study reports that colonoscopies done with suboptimal bowel preparation are associated with relatively high adenoma (precancerous polyp) miss rates, suggesting that suboptimal bowel preparation substantially decreases colonoscopy effectiveness and may mandate an early follow-up examination. In this study, in the context of suboptimal bowel preparation, of all adenomas identified, 42 percent were discovered only during a repeat colonoscopy, which was necessitated by an inadequate preparation during the first colonoscopy.
