Abstract
Bulimia nervosa is one of the eating disorders. Psychological manifestations of this disease, such as guilt or denial, may interfere with patient communication. The patients with bulimia nervosa are most commonly between ages of 17 and 25 years old, and often maintain normal body weight. It is not easy to screen out and diagnose bulimia nervosa patients at the emergency department. We reported two bulimia nervosa patients who visited our emergency department with abdominal distension, and one of them died of abdominal compartment syndrome. We confirmed collapse of the abdominal aorta and key arteries in enhanced abdominal computed tomography. Promptly, we performed gastrostomy for reduction of abdominal pressure, but she finally succumbed due to multiple organ failure 12 hours after the surgery.
