Abstract

Background: The prevalence of missed polyps in patients with inadequate bowel preparation on screening colonoscopy is unknown. Objective: To determine the prevalence of missed adenomas in average-risk patients presenting for screening colonoscopy who are found to have inadequate bowel preparation. Design: Retrospective chart review. Endoscopy and pathology reports were examined to determine the characteristics of polyps. Data from repeat colonoscopies were collected through 2010. Setting: Outpatient endoscopy center at an academic medical center. Patients: This study involved patients who underwent outpatient average-risk screening colonoscopy between 2004 and 2009 documented to have inadequate bowel preparation and who had colonoscopy to the cecum. Main Outcome Measurements: Initial adenoma detection rate and adenoma detection rate on follow-up examination. Results: Inadequate bowel preparation was reported on 373 patients, with an initial adenoma detection rate of 25.7%. Of 133 patients who underwent repeat colonoscopy, 33.8% had at least 1 adenoma detected, and 18.0% had high-risk states detected (
