[Severe lower digestive hemorrhage in Crohn's disease].

Severe or massive lower gastrointestinal bleeding is an unusual complication of inflammatory bowel disease that has traditionally associated with ulcerative colitis, although it can also appear in 0.6-2% of the cases in Crohn's disease. Two cases of severe lower gastrointestinal bleeding in Crohn's disease, one of them with ileocolic and another with ileal involvement are presented. Surgical treatment is supported by potential severity, high frequency of the relapse and data indicate a good prognosis after intestinal resection. It can be performed immediately if the persist bleeding or elective, as the 2 cases that we present, in the patients that are stabilized.
