The aim of this study was to evaluate the accuracy of multidetector CT in patients with Crohn's disease (CD) relapse after ileocolic resection compared with endoscopy. Thirty-four patients were studied by endoscopy and multidetector CT, after oral administration of polyethylene glycol solution (n = 21) or after administration of methylcellulose via nasojejunal tube (n = 13). In CT examinations we evaluated the presence of mural thickening, target sign, perienteric stranding, comb sign, fibrofatty proliferation and complications. Endoscopic results were classified in accordance with Rutgeerts score (from 0 to 4). The statistical evaluations were carried out by using Fisher's exact text and chi (2) testing (p < 0.05, statistically significant difference). Sensitivity, specificity and accuracy of the CT were 96.9%, 100% and 97%, respectively. We found a statistically significant correlation between an endoscopic score of 4 and the CT signs of target sign, perienteric stranding, comb sign and fibrofatty proliferation, and between scores 1 and 2 and mucosal hyperdensity without or with mural thickening, respectively (p < 0.05). Moreover, only CT identified the presence of jejunal and proximal ileum disease in two and three patients, respectively, and fistulas in three patients. CT is a reliable method in the diagnosis of CD relapse and shows agreement with the approved endoscopic Rutgeerts score.

Abstract

The aim of this study was to evaluate the accuracy of multidetector CT in patients with Crohn's disease (CD) relapse after ileocolic resection compared with endoscopy. Thirty-four patients were studied by endoscopy and multidetector CT, after oral administration of polyethylene glycol solution (n = 21) or after administration of methylcellulose via nasojejunal tube (n = 13). In CT examinations we evaluated the presence of mural thickening, target sign, perienteric stranding, comb sign, fibrofatty proliferation and complications. Endoscopic results were classified in accordance with Rutgeerts score (from 0 to 4). The statistical evaluations were carried out by using Fisher's exact text and chi (2) testing (p < 0.05, statistically significant difference). Sensitivity, specificity and accuracy of the CT were 96.9%, 100% and 97%, respectively. We found a statistically significant correlation between an endoscopic score of 4 and the CT signs of target sign, perienteric stranding, comb sign and fibrofatty proliferation, and between scores 1 and 2 and mucosal hyperdensity without or with mural thickening, respectively (p < 0.05). Moreover, only CT identified the presence of jejunal and proximal ileum disease in two and three patients, respectively, and fistulas in three patients. CT is a reliable method in the diagnosis of CD relapse and shows agreement with the approved endoscopic Rutgeerts score.
