Accuracy of bedside emergency physician performed ultrasound in diagnosing different causes of acute abdominal pain: a prospective study.

OBJECTIVE: Abdominal pain is a common complaint in the emergency department and accurate diagnosis of its etiology may affect the patient's outcome.
METHOD: Patients with abdominal pain underwent ultrasound study first by trained emergency physicians and then by radiologists blinded to emergency physician's results. RESULT: Emergency physician who performed bedside ultrasound had 78% diagnostic accuracy. Emergency physicians showed better results in diagnosing some entities (abdominal aortic aneurysm and renal stones) than the others (acute appendicitis, cholelithiasis, and cholecystitis).
CONCLUSION: Bedside ultrasound can accurately identify the etiology of acute nontraumatic abdominal pain in the hands of emergency physicians.
