Abstract
An eighty-three-year old woman was transferred to our hospital with abdominal pain and vomiting. She had been taking warfarin for two years. Enhanced abdominal computed tomography showed a thickened jejunum and fluid collection which appeared to be bloody ascites. An emergency operation was performed. Intraoperatively we found a mesenteric hematoma which was pressing on the mesenteric vein so tightly that the jejunum was congested, but free of necrosis. No surgical procedure was performed but we placed a jejunal tube for intestinal decompression. The patient's post operative course was uneventful. This is a rare case of mesenteric hematoma which was extremely difficult to be diagnosed preoperatively, and was thought to be caused by anticoagulation medication.
