Predictive factors for inadequate colon preparation before colonoscopy.

Area of Science:

• Gastroenterology
• Medical Diagnostics

Background:

• Effective colonoscopy relies on adequate bowel preparation.
• Identifying patients at risk for poor bowel preparation is essential for procedural success.

Purpose of the Study:

• To identify predictive factors for poor colon preparation before colonoscopy.

Main Methods:

• Prospective study involving 703 patients.
• Evaluated patient characteristics, diet, polyethylene glycol (PEG) volume, and stool characteristics.

Main Results:

• Univariate analysis showed factors like body weight, BMI, waist circumference, and meal residue score were related to inadequate preparation.
• Multivariate analysis identified waist circumference, meal residue score, and last stool characteristics as significant predictors of poor bowel preparation.

Conclusions:

• Patients consuming high-residue diets or having semisolid last stools are at higher risk for poor bowel preparation.
• Consideration for rescheduling may be beneficial for at-risk patients to ensure optimal colonoscopy outcomes.
