[What does the visceral surgeon need to know about computed tomography in the diagnostic work-up of the acute abdomen?]. / Was muss der Viszeralchirurg über den Einsatz der Computertomografie in der Abklärung des akuten Abdomens wissen.

The acute abdomen is a very serious yet common condition of patients presenting in the emergency department. The clinical symptoms of patients with acute abdomen are often unspecific. The responsibility of the surgeon in charge is to differentiate acute life-threatening from less serious conditions with a high level of diagnostic accuracy in a minimal period of time. Imaging represents a cornerstone in the diagnostic work-up of patients with acute abdomen. Computed tomography (CT) is increasingly utilised to detect emergency conditions in patients with acute abdomen. In this review article we aim to elaborate the role of CT in the imaging strategy for acute abdomen in comparison to conventional radiography, ultrasonography and magnetic resonance imaging. In addition, relevant factors pertaining for the indication of CT such as exposure to ionising radiation and safety of iodinated contrast media are discussed.
