[Role of ultrasonography in the study of patients with acute pancreatitis].
The aim of the present study is to establish the role of ultrasound examination (US) in the diagnosis of acute pancreatitis and its ability in differentiating mild or edematous acute pancreatitis (EAP) from severe or necrotizing acute pancreatitis (NAP) in order to indicate further diagnostic procedures and appropriate therapy. Forty patients with clinical suspect of acute pancreatitis were examined with US. All of them were followed-up clinically and with laboratory tests. Nineteen patients underwent a CT examination with contrast media and one without. In 28 cases US diagnosed acute pancreatitis in agreement with clinical and laboratory data. US identified 19 patients with EAP and 9 with NAP. CT, performed in 20 cases on the basis of clinical and US findings, confirmed US diagnosis in 19 cases while in 1 patient CT identified a NAP instead of the EAP suggested by US. According to our results, US is an easy-to-perform and accurate method for the diagnosis of acute pancreatitis and effective in differentiating EAP from NAP; it is also useful in suggesting further diagnostic procedures such as contrast-enhanced CT required in patients with NAP to assess the extension of peripancreatic fluid-collections and possible complications.
