Brief Summary
Bowel preparation is closely llined to the quality of colonoscopy, inadequate bowel preparation (IBP) could lead to higher miss rate of adenomas, patients' discomfort and higher health expense. For the patients with possible IBP before the examination, it may be better to cancel the colonoscopy and repeat bowel preparation through modified or enhanced strategies. Thus, it is important to set up a model to predict the quality of bowel preparation individually.

Outcome Measures
Primary Outcomes (1)
Boston bowel preparation quality scale
A 10-point scale (0 is worst, 9 is best)
1 hour
Study Arms (2)
Training cohort
This cohort was used to establish the bowel preparation score (BPS).
Validation cohort
This cohort was used to verify the bowel preparation score (BPS).
Interventions
Patients were asked to complete a questionnaire before colonoscopy. Bowel preparation was subsequently assessed by single endoscopist in each center using Boston bowel preparation quality score (BBPS). Both univariate and multivariate logistic regression models were used to identify high-risk factors associated with IBP and a predicting model with the bowel preparation score (BPS) was developed in the training cohort.
Patients were asked to complete a questionnaire before colonoscopy. The predicting modle established by the training cohort will be used to assessing the preparation of validation cohort. The result will compared with endoscopists assessment of preparation.
Eligibility Criteria
This is a prospective study involving two tertiary-centers in China.
You may qualify if:
- Patients aged 18-90 years old who undergoing colonoscopy
You may not qualify if:
- failed colonoscopy because of technical chanllenge or poor tolerance of patients
- history of colorectal surgery
- prior finding of severe colonic stricture or obstructing tumor
- dysphagia
- compromised swallowing reflex or mental status
- significant gastroparesis or gastric outlet obstruction or ileum
- known or suspected bowel obstruction or perforation
- pregnancy
- unable to give informed consent
