Colorectal Polyps Clinical Trial
Official title:
Free-residue Nutrients for the Bowel Preparation of Colon Capsule Endoscopy
Colon capsule endoscopy(CCE) is a new diagnostic method of colonic lesions.It has advantages of no requirement for sedation and air insufflation.The bowel preparation has a closely relationship with yield of diagnosing diseases.Bowel preparation of CCE is not only to clean the colon but also to promote capsule propulsion.Now there is not an optimal method for CCE.
Objective: In this study, a new bowel preparation regime of the colon capsule is used.This
regime combines free-residue nutrients and polyethylene glycol (PEG) to achieve a better
preparation quality.
Methods: Participants who underwent a diagnostic colonoscopy examination that demonstrated a
colorectal polyps that required endoscopic treatment will be recruited to patients in the
study. The first 32 participants receive a traditional low fiber diet two days before the
test.Then the patients will take 2L polyethylene glycol (PEG) at 21:00-23:00 before the test
day and 2L PEG at 05:00-07:00 on the test day for bowel preparation. The subsequent 30
participants receive two-days free-residue nutrients without other diet before the test.Then
the patients will take 2L PEG at 05:00-07:00 on the examination day for bowel preparation.
Then they will take 5mg mosapride citrate at 8:00 and ingest the colon capsule at 8:30.0.75L
and 0.50L PEG are administered as boosters.And the therapeutic endoscopy will be given on
the following day.Before the therapeutic colonoscopy, the participants will take 2L PEG. The
colon capsule results will be reviewed by two experienced endoscopists who are blinded to
first endoscopy results.
