Risk factors for inadequate bowel preparation before colonoscopy: A retrospective cohort study

Area of Science:

• Gastroenterology
• Endoscopy
• Surgical Preparation

Background:

• Effective bowel preparation is crucial for colonoscopy and endoscopic surgery.
• Adequate cleansing enhances lesion detection and reduces procedural risks.

Purpose of the Study:

• Investigate inadequate bowel preparation rates in colonoscopy patients.
• Identify factors contributing to poor bowel preparation.
• Propose interventions to improve bowel cleansing.

Main Methods:

• Retrospective cohort study of 484 patients undergoing colonoscopy.
• Data collected: patient demographics, disease variables, Boston Bowel Preparation Scale.
• Logistic regression analysis identified factors associated with inadequate preparation.

Main Results:

• Inadequate bowel preparation rate was 25.8% (125/484).
• Key factors: history of colorectal surgery (OR=5.814), low-residue diet (OR=0.145), laxative timing (OR=1.447).
• Exercise and bowel movement frequency also showed associations (P < 0.05).

Conclusions:

• Surgical history and adherence are key factors in bowel preparation quality.
• Dietary changes, optimized laxative timing, and physical activity guidance are recommended.
• Tailored strategies for high-risk patients can improve colonoscopy accuracy.
