| pubmed-article:19491841 | pubmed:abstractText | The effectiveness of colonoscopy in preventing colon cancer depends on adenoma detection and removal. Adequacy of bowel preparation, careful mucosal visualization, and adequate withdrawal time are known to affect adenoma detection rate (ADR). Physician fatigue, which usually increases as the day progresses, might impair ADR. The aim of this study is to assess the effect of timing of colonoscopy, morning vs. afternoon, on ADR. | lld:pubmed |
