Blunt abdominal trauma is a common presentation to the emergency department. Ischemic colitis is a rare complication of this and its possible sequelae are important for an emergency physician to recognize. A 21-year-old man presented to the emergency department with abdominal pain and hourly episodes of bright red blood per rectum shortly after being kicked in the stomach at his jujitsu class. He had no significant medical history, and results of his systems review were otherwise unremarkable. On examination, he appeared well, with normal vital signs. He had mild lower abdominal tenderness, but there were no peritoneal signs present. There was blood on the digital rectal examination. His hemoglobin, platelet, and international normalized ratio levels were normal and his abdominal radiograph was unremarkable. The gastroenterology service was contacted because of the hematochezia and a flexible sigmoidoscopy was performed. The sigmoidoscopy showed erythema, ulceration, and edema of a segment in the left colon, consistent with ischemic colitis. This was later confirmed on biopsy. A computed tomography (CT) scan of the abdomen was conducted, which revealed left colonic inflammation consistent with colonic ischemia. There was no mesenteric vascular thrombosis or mesenteric hematoma found on CT. His hematochezia and abdominal pain subsided spontaneously, and he was discharged home. This case illustrates transient ischemic colitis as a potential presentation of blunt abdominal trauma, and emergency physicians should consider this uncommon diagnosis in the differential diagnosis of patients presenting after abdominal trauma.
