title: Role of surgeon-performed ultrasound on further management of patients with acute abdominal pain: a randomised controlled clinical trial.
abstract: BACKGROUND
  The use of bedside ultrasound performed by the surgeon or emergency physician on duty at the emergency department is increasing. A study was performed which is the first randomised study to evaluate the benefits of surgeon-performed ultrasound for the management of the acute abdomen.
  
  
  METHODS
  800 patients who attended the emergency department at Stockholm South General Hospital, Sweden for abdominal pain were randomised either to receive or not receive surgeon-performed ultrasound as a complement to routine management. Outcome measures included the number of complementary investigations, time spent in the emergency department, admission rate, length of hospital stay if admitted, admission to surgery and timing of surgery if required.
  
  
  RESULTS
  The number of complementary ultrasound examinations was considerably higher in the group who did not receive bedside ultrasound (18.8 percentage points difference, p<0.001). The admission rate was lower in the ultrasound group (7.2 percentage points difference, p = 0.041) and the proportion of patients requiring surgery submitted for surgery directly from the emergency department was higher in the ultrasound group (18.5 percentage points difference, p = 0.013).
  
  
  CONCLUSIONS
  This study shows benefits in the management of the acute abdomen resulting in fewer further requested examinations, fewer admissions and shorter lead times to surgery. On the basis of these results, it is recommended for implementation in emergency departments.
