Trial summary

Patients with constipation are more likely to have poor bowel preparation quality due to slow gut motility and poor emptying ability. Gum chewing, as a proxy of sham feeding, is a very simple way used to accelerate gut motility. Read more about this study

About this study

Official title: Effect of Chewing Gum Combined With Manual Enhanced Instructions by WeChat on the Bowel Preparation Quality for Colonoscopy in Patients With Constipation: a Randomized Controlled Trial

Patients with constipation are more likely to have poor bowel preparation quality due to slow gut motility and poor emptying ability. Gum chewing, as a proxy of sham feeding, is a very simple way used to accelerate gut motility. And a previous study found that enhanced instructions by WeChat could improve bowel preparation quality. Thus, investigators conducted a single-center randomized controlled trial to explore the effect of chewing gum combined with manual enhanced instructions by WeChat on the bowel preparation quality for colonoscopy in patients with constipation.

Read the detailed description

In this randomized controlled trial, consecutive outpatients with constipation for colonoscopy are screened and then randomized into two groups. All enrolled patients will receive 3 liter polyethylene glycol (PEG) for bowel preparation. Patients in the chewing gum and WeChat group (n = 75) are further advised to chew one piece of sugarless gum for 20 minutes after drinking each 1 liter PEG; additionally, they will receive enhanced instructions via WeChat before two days and one day of colonoscopy to further inform how to chew gum and highlight the importance of adequate bowel preparation. Patients in the control group (n = 75) are guided by regular instructions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bowel preparation quality

    Bowel preparation quality is evaluated by the Boston bowel preparation scale (BBPS) score:

    Segment score 0: unprepared colon segment with mucosa not seen due to solid stool that cannot be cleared.

    Segment score 1: portion of mucosa of the colon segment seen, but other areas of the colon segment not well seen due to staining, residual stool and/or opaque liquid.

    Segment score 2: minor amount of residual staining, small fragments of stool and/or opaque liquid, but mucosa of colon segment seen well.

    Segment score 3: entire mucosa of colon segment seen well with no residual staining, small fragments of stool and/or opaque liquid.

    Measured: During colonoscopy procedure, an average of 30 minutes

Secondary outcomes (4)
  1. The number of polyp and/or adenoma

    The number of polyp and/or adenoma is defined as the number of adenoma/polyp detected during colonoscopy.

    Measured: During colonoscopy procedure, an average of 30 minutes

  2. Polyp and/or adenoma detection rate

    Polyp and/or adenoma detection rate (PDR/ADR) is defined as the proportion of patients with at least one histologically confirmed adenoma/polyp detected during colonoscopy.

    Measured: During colonoscopy procedure, an average of 30 minutes

  3. Adverse events

    Adverse events are defined as the occurrence of gastrointestinal symptoms during bowel preparation, including nausea, vomiting, abdominal pain, and bloating.

    Measured: During colonoscopy procedure, an average of 30 minutes

  4. Cecal intubation time

    Cecal intubation time (CIT) is defined as the time from the insertion of the colonoscope tip into the anal verge until reaching the cecal base or cecal end.

    Measured: During colonoscopy procedure, an average of 30 minutes
