title: Computed tomography of bowel wall in patients with Crohn's disease: relationship of inflammatory activity to biological indices.
abstract: Bowel wall thickening in Crohn's disease can be demonstrated by Computed Tomography. The aim of this investigation was to correlate different patterns of bowel wall thickening, detected with Computed Tomography, with serological parameters of activity of Crohn's disease. Thirty-eight patients (24 males, 14 females, aged 21 to 62 years) were studied. Patients were divided into 3 groups according to Computed Tomography appearance of bowel wall: 1) homogeneous symmetrical thickening of wall; 2) bowel showing a layer of submucosal low attenuation; 3) scarred narrowing of wall producing stenosis. A patient was considered to have biochemically active disease if at least 2 of the following parameters were abnormal: ESR, C-reactive protein, seromucoids, serum albumin, serum alpha-2 globulin. The first group comprised 20 patients (16 active disease, 4 inactive) and the second group 13 (all inactive); the 2 groups showed a significant difference (Fisher exact test: p < 0.0005) in biological activity. Since only 5 patients belonged to the third group (3 active, 2 inactive disease), no definite conclusion can be drawn on the possible correlation between this Computed Tomography pattern and activity of disease. Results shows a correlation between Computed Tomography patterns of bowel wall disease and biochemical activity of Crohn's disease.
