[Cryptogenetic ulcerative colitis. Our clinical experience with new therapeutic approaches].

Sixteen patients with flare-ups of ulcerative colitis were studied. Before and after treatment, patients were submitted to the customary laboratory tests and to x-ray (contrast enema) and endoscopic examination, biopsy material being harvested during the latter. Treatment consisted in the oral administration of 2-4 g 5-ASA daily for 30 days. Only one patient did not tolerate 5-ASA which was withdrawn. All other patients had good or very good results with remission of symptoms.
