Biopsy and histologic examination of stricture was performed and showed no dysplasia. After the full discussion with the patient, biologic therapy (adalimumab: 160 mg sc, then-14 days later: 80 mg sc and 14 days later: 40 mg every 2 weeks sc) was started. An oral steroid therapy for a short period (40 mg/day prednisolone for 1 month, then gradually decreased for the last 2 months

and stopped) was started. His condition was dramatically improved. Four months later, magnetic resonance imaging enterography was performed and showed significantly improvement on the narrowing segments, particularly in the sigmoid and right colon (Fig. 3–5). He had no complaints during the follow-up for the last 18 months of adalimumab therapy. Radiologic and endoscopic examinations SB203580 datasheet were performed and showed in Fig. 6–8. Conclusion: Stricture development is an ongoing www.selleckchem.com/products/apo866-fk866.html dynamic process which includes both inflammatory and fibrotic components. Although colonic stenosis is a rare complication of CD, it is a typical complication by time because of transmural involvement of the bowel wall in CD. Management of CD with colonic stricture has not been clearly defined. Efficacy of biologics on stenosing form of CD was not established and

the data insufficient so far. The main concern is that biologic agents might increase stricture because of rapid mucosal healing induced fibrosis or rapid relief might cause perforation in the colon. According to our presented study, biologic agents might be a safe therapy option with their antifibrotic proporties in patients with stenosing CD, providing special patients should be carefully followed during the biologic therapies.

Though CT enterography (CTE) yields striking findings in the small bowel of CD, its role in differentiating CD from ITB is undefined. This prospective study aimed to investigate the value of CTE findings in the differential diagnosis between CD and ITB. Methods: 105 consecutive patients (67 CD, 38 ITB) who underwent CTE were enrolled. CTE findings and colonoscopic parameters were compared between CD and ITB by blinded reviewers. On the basis of univariate and multiple logistic regression analyses, a diagnostic algorithm combining colonoscopy and CTE was formulated. The diagnostic accuracy of this algorithm was validated. Interobserver agreement was assessed by using weighted k statistics.
