Importance of Bowel Habits in Predicting Inadequate Bowel Preparation: A Prospective Observational Study

Area of Science:

• Gastroenterology
• Endoscopy
• Clinical Research

Background:

• Inadequate bowel preparation (BP) compromises colonoscopy efficacy and quality.
• Constipation is a known predictor of poor BP, but specific bowel habit details remain underexplored.

Purpose of the Study:

• To investigate the association between specific bowel habits, constipation severity, and inadequate BP.
• To identify predictors of inadequate BP in patients undergoing colonoscopy.

Main Methods:

• Prospective observational study of 1054 patients undergoing colonoscopy.
• Assessment of bowel habits, constipation severity (constipation scoring system), and BP quality (Boston Bowel Preparation Scale).
• Multivariate logistic regression analysis to identify predictors of inadequate BP.

Main Results:

• 10% of patients (105/1054) had inadequate BP.
• Increased constipation severity correlated with higher risk of inadequate BP (P=0.01).
• Frequent straining (OR 2.09) and chronic stimulant laxative use (OR 2.57) were significant predictors of inadequate BP.

Conclusions:

• Frequent straining and chronic stimulant laxative use are key predictors of inadequate BP.
• Consider intensified bowel preparation protocols for constipated patients exhibiting straining and chronic stimulant laxative use.
