简要总结
Chronic constipation is one of the risk factors of inadequate bowel preparation, which could influence the effect of colonoscopy. The risk factors associated with inadequate bowel preparation in constipated patients remains unclear. Here the investigators investigated the high risk factors which might have influence on bowel preparation quality in a prospective cohort of patients with functional constipation.

结局指标
主要结局
adequate rate of bowel preparation ≥6 with each segment ≥2
时间窗: 6 months
The adequacy of bowel preparation is defined as Boston Bowel Preparation Scale (BBPS), a 4-point scoring system applied to each of 3 broad regions of the colon: the right side, the transverse section, and the left side. They were summed to give the total BBPS score, which ranged from 0 to 9.
次要结局
- polyp detection rate(6 months)
