Inflammatory bowel disease.

This review summarizes important publications that have appeared during the last year dealing with imaging techniques and endoscopy, as well as the management of low-grade dysplasia and stenosis in inflammatory bowel disease. Magnetic resonance enteroclysis and capsule endoscopy are currently emerging as new imaging techniques for the small bowel in Crohn's disease. While magnetic resonance enteroclysis is, at least in Europe, increasingly being used as a reference method, the value of capsule endoscopy for the management of inflammatory bowel disease is still being evaluated. Chromoendoscopy is being studied in patients with long-lasting ulcerative colitis and may be a promising and sensitive technique for the diagnosis of dysplasia. However, there are conflicting data regarding the appropriate management when low-grade dysplasia is diagnosed in patients with ulcerative colitis. Endoscopic dilation can often be successfully carried out in cases of intestinal stenosis. The results of long-term follow-up studies indicate that several dilation procedures are often necessary and that a relatively high percentage of patients still have to undergo surgery.
