Diagnostic Modalities for Inflammatory Bowel Disease: Serologic Markers and Endoscopy.
The evaluation, diagnosis, and monitoring of inflammatory bowel disease (IBD) has improved significantly over the past few decades. However, differentiation and management of the subtypes of IBD (Crohn's disease, ulcerative colitis, and indeterminate colitis) can still be challenging. The evolution of serologic markers has improved our understanding of the pathogenesis and natural history of IBD. In addition, advancements in endoscopy and endoscopic scoring systems have improved the accuracy of diagnosis and the efficacy of surveillance of IBD patients. This article reviews the recent literature on serologic markers, endoscopy, and endoscopy scoring systems.
