ENDOSCOPIC DIAGNOSIS OF INFLAMMATORY BOWEL DISEASE-RELATED DISEASES

Abstract

The diagnosis of inflammatory bowel disease (IBD) including ulcerative colitis (UC) and Crohnʼs disease (CD) in the absence of typical endoscopic features is often challenging. In such cases, UC or CD cannot be definitively diagnosed, and these conditions are categorized as “inflammatory bowel disease-unclassified”. Recent technological advances have introduced balloon-assisted endoscopy and capsule endoscopy for the management of patients with chronic enteritis. These techniques enable the detection of mucosal lesions in the small intestine. Furthermore, these innovations have changed the diagnostic strategy of IBD and IBD-related diseases. In this review, we present an overview, as well as the clinical characteristics and endoscopic diagnosis of IBD-related diseases including intestinal Behçetʼs disease with simple ulcer, trisomy 8-associated enteritis, chronic enteropathy associated with the SLCO2A1 gene, and familial Mediterranean fever with enteritis.
