“…Although some studies have demonstrated that appropriate bowel preparation and use of prokinetic agents could improve the SBTT and the cecal completion rate of CE [17,24,25], the usefulness of such agents, in particular, for the completion rate of CE, is controversial. Although a positive effect of cisapride and Dai-kenchu-to on gastrointestinal dysmotility after abdominal surgery has been reported [26,27], it is unknown whether these prokinetic agents can really improve the transit time and the cecal completion rate of CE. This needs to be investigated by a prospective study in the future.…”
