Clinical Trial Summary

About 30% of patients were reported to suffer inadequate bowel preparation. So, it is desirable to prescribe personalized regimen according to patient's personal characteristics.

Description:

Colonoscopy is currently the main approach for detecting mucosal abnormalities in the whole colon. Inadequate bowel preparation is the predominant threaten to the efficacy of colonoscopy.Unfortunately, about 30% of patients were reported to suffer inadequate bowel preparation. In order to improve adequate bowel preparation rate, it is desirable to prescribe personalized regimen according to patient characteristics. We intend to improve adequate bowel preparation rate by deploying tailored bowel preparation strategy. There are many predictive factors of inadequate bowel preparation such as obesity, constipation, abdominal surgery and so on. By recognizing these risk factors of the patients , we can prescribe the patients with higher dose of bowel cleansing regimen to improve bowel preparation quality.
