Abstract:Abstract: Objective?To study on intestinal preparation of patients undergoing capsule endoscopy after colonoscopy while increase patients compliance without affecting bowel preparation quality.?Methods?The patients underwent capsule endoscopic examination after colonoscopy were retrospectively studied from January 2014 to December 2017, including 41 patients in the control group and 48 patients in the observation group (low dose polyethylene glycols group). The differences of intestinal visualization quality, capsule endoscopy findings, compliance and adverse reaction were compared between the two groups.?Results?The intestinal visualization quality of the observation group was better than that of the control group (64.6% vs 41.5%, P?0.05). There was no significant difference in the capsule endoscopy findings and adverse reaction between the two groups. The compliance was all good.?Conclusion?The intestinal preparation was better by using low dose polyethylene glycols (PEG) undergoing capsule endoscopy after colonoscopy, and the compliance was fine. It was worth popularizing application clinically.
