[Inflammatory bowel disease--diagnosis and therapy].

The first intention in the management of patients with inflammatory bowel disease (IBD) is the improvement of quality of life. It is important to avoid unnecessary investigations and to protect the patients from therapeutic approaches, which efficacy is not proven. The following remarks are based on the guidelines of The German Society of Gastroenterology for diagnosis and therapy of ulcerative colitis and Crohn's disease, which include an accurate diagnosis, the treatment of the acute phase, the maintaining of remission and the management of complications. The therapy depends on the severity of the acute phase and on the localisation of the disease. Immunosuppressive therapy with azathioprine or mercaptopurine is indicated in patients with steroid-dependent or steroid-resistant disease.
