Can we predict an incomplete capsule endoscopy? Results of a multivariate analysis using a logistic regression model

Area of Science:

• Gastroenterology
• Medical Imaging
• Diagnostic Procedures

Background:

• Small bowel capsule endoscopy (SBCE) is crucial for visualizing the small intestine.
• Incomplete SBCE examinations, failing to reach the cecum, occur in 15-35% of patients.
• Incomplete examinations lead to diagnostic delays and increased healthcare costs.

Purpose of the Study:

• To determine the incidence of incomplete SBCE examinations.
• To identify predictive risk factors for incomplete SBCE, excluding capsule retention.
• To inform strategies for improving examination completion rates.

Main Methods:

• Analysis of 1,894 consecutive SBCE examinations.
• Inclusion of demographic, medical history, biochemical, and procedural data.
• Multivariate logistic regression analysis to identify predictive factors for incomplete examinations.

Main Results:

• The incidence of incomplete SBCE (excluding retention) was 10.1%.
• Predictive factors for incomplete examinations included age > 65 years (OR: 1.99), gastric transit time > 41 minutes (OR: 2.60), and small bowel transit time > 286 minutes (OR: 3.52).
• These factors significantly increased the probability of incomplete examinations.

Conclusions:

• Age over 65, prolonged gastric transit, and extended small bowel transit are significant predictors of incomplete SBCE.
• Age and gastric transit time are identifiable before procedure completion.
• Proactive interventions, such as pharmacologic or endoscopic measures, can be considered to prevent incomplete examinations.
