Diabetes mellitus accompanied by nonocclusive colonic ischemia.

A 70-year-old man with diabetic triopathy was hospitalized with left lower quadrant abdominal pain and tenderness, muscle guarding and absent bowel sounds. Three hours after admission, creatine phosphokinase (CPK) was elevated and an abdominal plain film X-ray showed intestinal gas retention, indicating paralytic ileus due to inferior mesenteric artery occlusion. Urokinase (60,000 units/day) and heparin (10,000 units/day) were administered. Angiography showed no occlusion in the mesenteric artery. On the 16th day, the abdominal signs had disappeared and CPK was normalized. We diagnosed this case as nonocclusive colonic ischemia because of the hemorheological abnormalities due to diabetic triopathy and the hypercoagulable state.
