We aimed to further investigate the optimal small bowel cleanse method by comparing the efficacy of 4 L of clear liquids, 2 L of polyethylene glycol (PEG), and 4 L of PEG on the image quality of VCE. <b><i>Methods:</i></b> A randomized controlled, non-inferiority trial was performed comparing 4 L of clear liquids (Group A), 2 L of PEG (Group B), and 4 L of PEG (Group C). The primary endpoint was image quality between the groups. The secondary endpoints included patient tolerability and side effects. <b><i>Results:</i></b> Eighty-one patients were analyzed in group A, 84 patients were analyzed in group B, and 80 patients were analyzed in group C. Image quality scores revealed 4 L of clear liquids to be non-inferior to 2 L of PEG, and 2 L of PEG to be non-inferior to 4 L of PEG (<i>p</i> < 0.0167). Group A had a lower difficulty of completion rate than Group B and Group C and a lower rate of side effects when compared to Group C (<i>p</i> < 0.0167). <b><i>Conclusion:</i></b> Four liters of clear liquids should be considered a routine method for small bowel preparation prior to VCE. 2018-09-13 12:47:47 Video capsule endoscopy Small Bowel Preparation Image quality
