Disseminated intravascular coagulation in an ulcerative colitis case not associated with surgery.

We describe a case of disseminated intravascular coagulation in an ulcerative colitis case. This is the first reported case not associated with surgery, and was successfully treated with conservative therapy. The combined use of heparin and gabexate mesilate was considered to be very effective for improving this condition, although a slight increased in rectal bleeding was recognized for a short time.
