Summary
Double-contrast barium enema examination (DCBE) and colonoscopy are complementary for diagnosing inflammatory bowel disease. They effectively detect most colon lesions, aiding in Crohn disease and ulcerative colitis diagnosis.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
- Colorectal Surgery
Background:
- Idiopathic inflammatory bowel disease (IBD) encompasses Crohn disease (CD) and ulcerative colitis (UC).
- Accurate diagnosis and monitoring of IBD rely on effective imaging modalities.
Purpose of the Study:
- To evaluate the diagnostic performance of double-contrast barium enema examination (DCBE) and colonoscopy.
- To compare their effectiveness in identifying colonic lesions in IBD patients.
Main Methods:
- A prospective, blinded study involving 99 patients with established CD (n=51) or UC (n=48).
- Correlation of radiographic (DCBE) and endoscopic (colonoscopy) findings using a standardized evaluation sheet.
Main Results:
- Substantial to almost perfect agreement (>80%) was observed for most evaluated colon segments.
- High agreement (kappa > 60%) was achieved for detecting aphthoid erosions and fine granularity.
Conclusions:
- DCBE and colonoscopy are complementary for optimal detection of mucosal and structural colon lesions in IBD.
- Both modalities excel in identifying lesions with mucosal relief distortion but may miss subtle inflammatory changes.
