[X-ray and endoscopic diagnosis of ulcerative colitis and Crohn disease]

The indication for radiologic or endoscopic examinations in ulcerative colitis and Crohn's disease depends on the stage of the disease. Advantages of the colonoscopy are the possibility to take biopsies, the coloured few of lesions and the avoidance of X-rays in the management of young patients. Radiology is superior to endoscopy in estimating shortening of the bowel, stenoses and fistulas.
