The aim of the study was to asses the clinical value of percutaneous abdominal ultrasonography in diagnosis, staging and surgical treatment of patients with pancreatic carcinoma.Material and methods. 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.Results. 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%.Conclusions. Percutaneous abdominal ultrasonography has high diagnostic accuracy in diagnosis, staging and predicting surgical treatment of patients with pancreatic carcinoma.

Primary adenocarcinoma of the vermiform appendix is a rare clinical condition. It usually presents as an acute abdominal process or as a mass in the right lower quadrant. The gross pathologic and microscopic characteristics of this disease are the same as for colon carcinoma and carry a serious prognosis. We report a case of a 64-year old male patient presenting symptoms of acute appendicitis. The patient underwent laparoscopic appendectomy that revealed a severely inflamed appendix. Histopathological examination has shown that it was a poorly differentiated, high grade adenocarcinoma invading the periappendicular fat. According to the histopathological findings, a right hemicolectomy was further advised and performed. Right hemicolectomy is the generally recommended method of treatment for invasive adenocarcinoma of the appendix
