Abstract

The preparation for video capsule endoscopy (VCE) of the bowel suggested by manufacturers of capsule endoscopy systems consists only of a clear liquid diet and an 8-hour fast. While there is evidence for a benefit from bowel preparation for VCE, so far there is no domestic consensus on the preparation regimen in Korea. Therefore, we performed this study to recommend guidelines for bowel preparation before VCE. The guidelines on VCE were developed by the Korean Gut Image Study Group, part of the Korean Society of Gastrointestinal Endoscopy. Four key questions were selected. According to our guidelines, bowel preparation with polyethylene glycol (PEG) solution enhances small bowel visualization quality (SBVQ) and diagnostic yield (DY), but it has no effect on cecal completion rate (CR). Bowel preparation with 2 L of PEG solution is similar to that with 4 L of PEG in terms of the SBVQ, DY, and CR of VCE. Bowel preparation with fasting or PEG solution combined with simethicone enhances the SBVQ, but it does not affect the CR of VCE. Bowel preparation with prokinetics does not enhance the SBVQ, DY, or CR of VCE.
