Brief Summary:
The purpose of this study is to evaluate whether surgeon-performed ultrasound as a supplement to clinical investigation when a patient presents with abdominal pain in the emergency department can improve the management of the patient.

Condition or disease Intervention/treatment Phase
Abdominal Pain Radiation: Surgeon-performed ultrasound Not Applicable

Detailed Description:
Surgeon-performed ultrasound bedside in the emergency department when a patient presents with abdominal pain is quite common in Continental Europe and USA. It is considered to be implemented at emergency departments all over Sweden. This is the first randomized study performed to evaluate the method. In our study we compare diagnostic accuracy and further management of patients admitted to the emergency department for abdominal pain, with or without examination with surgeon-performed ultrasound bedside.

Arm Intervention/treatment
Surgeon-performed ultrasound as intervention, as a complement to clinical investigation and standardized laboratory testing.
Radiation: Surgeon-performed ultrasound
After clinical investigation including standardized laboratory tests the patient in the intervention arm is examined with abdominal ultrasound performed by the study surgeon.
Other Name: US
No Intervention: Control
Control group examined with clinical examination including standardized laboratory tests.

Primary Outcome Measures :
