A Practical Approach in Differentiating IBD From Other Causes of Enterocolitis

Area of Science:

• Gastroenterology
• Internal Medicine
• Clinical Diagnostics

Background:

• Inflammatory bowel disease (IBD) diagnosis presents unique challenges in Asia.
• Lack of a gold standard necessitates a multi-faceted diagnostic approach for IBD.
• Differentiating IBD from infectious mimics, particularly intestinal tuberculosis (ITB), is a significant clinical dilemma.

Purpose of the Study:

• To highlight the diagnostic challenges of IBD in the Asian context.
• To emphasize the importance of integrating various diagnostic modalities for IBD.
• To provide guidance on differentiating IBD from conditions like ITB.

Main Methods:

• Review of clinical, endoscopic, radiological, and histological features used in IBD diagnosis.
• Analysis of differential diagnoses, focusing on distinguishing IBD from infectious etiologies like ITB.
• Discussion of diagnostic strategies including patient history, targeted investigations, and histopathology.

Main Results:

• No single diagnostic method is specific for IBD.
• Clinical, endoscopic, radiological, and histological findings are often non-specific.
• Distinguishing Crohn's disease (CD) from ITB requires careful assessment.

Conclusions:

• Definitive IBD diagnosis is achievable in most cases through comprehensive evaluation.
• Empirical treatment may be initiated when diagnosis remains uncertain, requiring subsequent reassessment.
• Accurate differentiation of IBD from infectious diseases is crucial for appropriate patient management.
