Bowel preparation for colonoscopy
Brief summary
We have developed a novel inadequate bowel preparation prediction model based on a systematic review and meta-analysis. The goal of this multicenter observational study is to validate the accuracy of this model.
Detailed description
The primary outcome is quality of bowel preparation. The secondary outcomes include polyp/adenoma detection rate, willingness of undergoing colonoscopy again and adverse events.
Interventions
Patients use purgative for bowel cleansing before colonoscopy.

Eligibility
Inclusion criteria
1. adult patients (age is ≥18 years old); 2. patients undergoing colonoscopy; 3. written informed consent.
Exclusion criteria
1. patients undergoing emergent colonoscopy; 2. patients with major psychiatric disorders; 3. pregnant or breast feeding patients; 4. patients with contraindications for colonoscopy (e.g., heart failure, renal insufficiency); 5. patients suspected to have intestinal obstruction, stenosis or perforation; 6. poor compliance with the bowel preparation protocol (poor compliance is indicated if the dose of medication was \< 75% of the prescribed dose; 7. incomplete colonoscopy because of other circumstances apart from inadequate cleansing 8. patients previously enrolled in this study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quality of bowel preparation | During the procedure of colonoscopy | A total BBPS score ≥6 with BBPS score ≥2 for each colon segment was considered to have adequate bowel preparation. Each segment of the colon is scored from 0 to 3, with higher scores indicating superior cleansing, and summed for a total score that can range from 0 to 9. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Adenoma and/or polyp detection rate | During the procedure of colonoscopy | Proportion of patients with at least one adenoma and/or polyp detected during colonoscopy |
| Number of polyps and/or adenomas | During the procedure of colonoscopy | Number of polyps and/or adenomas detected during colonoscopy |
| Adverse events | Before the procedure of colonoscopy | Incidence of abdominal pain, bloating, nausea/vomiting after intake of purgative. |
