Background/Aims The miss rate of colon polyps and its related factors have not been clearly identified yet. This study aims to review the both on patient-level polyp-level analyze affecting such as those endoscopist, procedure, patient, polyp. Methods From August 2011 2013, patients who underwent elective second colonoscopy for resection polyps, sizes which were small enough be resected by biopsy forceps alone at first colonoscopy, enrolled retrospectively. Results: was 59.2% (234/395) 27.9% (578/2,068). There no significant difference in depending experience endoscopists or characteristics patients. In terms higher when performed afternoon (OR 1.632, p=0.046). It found that increased 4.595, p<0.001 <5 mm/OR 3.447, 5–10 mm), flat sessile 2.406, flat/OR 1.768, p=0.002 sessile), located left 1.391, p=0.007). Conclusions did influence accuracy polyp detection. However, fatigue is considered render detection less accurate. Also, large curves folds sigmoid are regarded a reason colon.
