Review of chronic ulcerative colitis cases at King Hussein Medical Centre, Jordan

Chronic ulcerative colitis is being encountered with increasing frequency in developing countries. In Amman, Jordan, the records of 372 patients with chronic ulcerative colitis diagnosed between 1994 and 2001 were reviewed. Bloody diarrhoea and crampy abdominal pain were the most common presenting symptoms (84% of patients). The mean age at onset was 31.8 years. In two thirds of patients the diagnosis was made more than 1 year after the onset of symptoms. The pattern of the disease differed from that in industrialized countries in the mild course of the disease, the absence of skin manifestations, and the rarity of colorectal cancer in our patients. The mortality rate was 6%.
