CED: Ultraschall ergänzt die Diagnostik zur Abgrenzung von Behçet-Erkrankungen

Objective/Aim: Differentiating the gastrointestinal (GI) involvement of Behçet’s disease (BD) and inflammatory bowel diseases (IBD) can be a diagnostic challenge. We previously reported that the wall thickness of the common femoral vein (CFV) is higher in BD patients compared to Crohn’s disease (CD) with a limited number of IBD patients with only CD. This study aimed to evaluate the CFV thickness measurement in BD patients and in a larger group of IBD patients including both ulcerative colitis (UC) and CD. Methods: The study included patients with BD (n=117), IBD (n=87, [53 CD, 34 UC]), and healthy gender-matched controls (HC) (n=85). CFV wall thicknesses were measured with Doppler ultrasonography. Results: Among BD patients, 70 (59.8%) had major organ (48 [41.0%] vascular, 21 [30.0%] ocular, 11 [15.7%] gastrointestinal, and 8 [11.4%] neurological) involvement. The mean right CFV thickness was 0.75±0.21 mm, 0.32±0.08 mm, and 0.28±0.13 mm for BD, IBD, and HC, respectively (p
