<bold>The aim of the study</bold> was to asses the clinical value of percutaneous abdominal ultrasonography in diagnosis, staging and surgical treatment of patients with pancreatic carcinoma.
<bold>Material and methods.</bold> Prospective clinical trial on diagnostic accuracy of percutaneous abdominal ultrasonography was conducted in 409 consecutive patients with pancreatic cancer which were operated on at the I Dept. of General Surgery in Cracow between 2000 and 2010.
<bold>Results.</bold> Diagnostic accuracy of percutaneous abdominal ultrasonography in pancreatic cancer was 91,1%. The accuracy in detecting different stages of local advancement according to TNM classification was assessed respectively 92.3%-T1, 91.3%-T2, 89.4%-T3, 92.1%-T4, a whole T1-T4 on 91.3%. Diagnostic accuracy of percutaneous abdominal ultrasonography in diagnosis of metastasis to lymph nodes, vascular infiltration, and resectability was respectively 80.7%, 86%, 91.4%.
<bold>Conclusions.</bold> Percutaneous abdominal ultrasonography has high diagnostic accuracy in diagnosis, staging and predicting surgical treatment of patients with pancreatic carcinoma.
