Clinical Report: Integrating Double-Balloon Enteroscopy into the Diagnostic Pathway for Suspected Small Bowel Crohn’s Disease

Overview

This study evaluates the integration of double-balloon enteroscopy (DBE) into the diagnostic pathway for suspected small bowel Crohn’s disease, highlighting the diagnostic yield of small bowel capsule endoscopy (SBCE) and factors influencing DBE referral. The findings suggest that SBCE is effective for initial assessment, while DBE is reserved for cases requiring further histological confirmation.

Background

Small bowel Crohn’s disease poses diagnostic challenges, often leading to delayed treatment. SBCE offers a non-invasive means to visualize the small bowel, but lacks the ability to obtain histological samples. DBE serves as a complementary tool, enabling direct assessment and therapeutic interventions, thus improving patient management in suspected cases of Crohn’s disease.

Data Highlights

Key Findings

• SBCE established or excluded inflammatory bowel disease in 70% of patients.
• DBE confirmed Crohn’s disease in 21% of patients referred after SBCE.
• Increasing age and diagnostic uncertainty on SBCE were significant predictors for DBE referral.
• The SBCE-to-DBE conversion rate was 30.4%.
• DBE should be reserved for cases requiring histological confirmation or therapeutic intervention.

Clinical Implications

Clinicians should consider SBCE as the first-line diagnostic tool for suspected small bowel Crohn’s disease due to its high diagnostic yield. DBE is indicated for patients with uncertain SBCE findings or those needing histological confirmation, thereby optimizing patient management and minimizing unnecessary procedures.

Conclusion

The integration of SBCE and DBE enhances the diagnostic pathway for small bowel Crohn’s disease, allowing for effective triage and targeted interventions. This approach may lead to improved patient outcomes through timely diagnosis and treatment.
