[Instrumental diagnosis for therapy decision making in abdominal injuries].

The aim of diagnostic procedures following abdominal injuries is rapid assessment of the necessity for surgical intervention and specification of the organ lesion, thus reducing the number of negative laparotomies. The extent of the diagnostic approach must be reduced in unstable patients. Sonography is the standard procedure in stable as well as in unstable patients, both in the initial period and the subsequent follow-up. CT-scan is complementary to sonography in detecting organ lesions. Sonographically guided puncture has replaced diagnostic peritoneal lavage. Laparoscopy following blunt abdominal injuries is not useful; however, it may be helpful following penetrating abdominal trauma.
