Conditions

Boston Bowel Preparation Scale, Bowel Cleansing Quality, Colonoscopy, Predictors

Brief summary

About 30% of patients were reported to suffer inadequate bowel preparation.

Detailed description

Risk factors, such as diabetes, constipation, history of intra-abdominal or pelvic surgery, etc, have been demonstrated to be important predictors for inadequate bowel preparation. The aim of the study is to create and verify a predictive model for inadequate bowel preparation in Chinese.
