Capsule studies can be reviewed by varying rates and speeds; however, the presence of significant debris is frustrating to the reviewer much like the excessive stool that tends to hinder the progress of a colonoscopist. Numerous studies have been published in regards to the advantages of an ideal preparation in the setting of capsule endoscopy. This most recent study by Wei et al. is another study that has demonstrated that a colonic preparation, in this situation, combined with simethicone given just prior to the capsule study results in improved visibility of the mucosa. In theory, this will lead to an improved diagnostic ability to limit excessive reading duration.
