Abstract
A 45-year-old man, who went into shock after he was cut external jugular vein with handicraft cutter, was brought into the hospital by ambulance. We ligated external jugular vein, and he survived. He complained left lower abdominal pain and bloody diarrhea for 4 days, right after our treatment. Colonoscopy revealed constriction with mucosal edema and multiple ulcers from sigmoid colon to descending colon. We diagnosed as shock-associated ischemic colitis after hemorrhagic shock. Only one similar case have been reported on the international literature.
