[Sonographically guided percutaneous fine needle puncture of space occupying processes of the abdomen and retroperitoneum].

In the past four years percutaneous ultrasonically guided fine needle aspiration biopsies of space occupying lesions of the abdomen and retroperitoneum wee performed on 180 patients. There were 71 aspirations of cystic and 169 aspirations of solid lesions. Amongst the latter pancreas was first with 67 followed by the liver with 58, the kidney with 31 and other organs of the abdomen with 13 aspirations.

[Accuracy of sonography in the diagnosis of diffuse liver parenchymal diseases--comparison of sonography and liver histology].

A prospective study has been carried out on 127 patients to test the accuracy of sonography in the diagnosis of diffuse liver diseases compared with histology based on percutaneous liver biopsy. Using sonographic criteria - size, margin, surface, elasticity, echo structure and sonic conductivity of the liver, hepatic veins and portal vein - and measuring the size of the gallbladder and the spleen, the following sonographic diagnoses were made: normal liver, fatty liver, fatty liver fibrosis, alcoholic hepatitis, chronic active hepatitis, cirrhosis. Sonographic diagnosis predicted histological diagnosis in case of normal liver in 56%, fatty liver 70%, alcoholic hepatitis 92%, chronic active hepatitis 63%, cirrhosis 79%.

[Sonographic study of the pancreas and the large epigastric vessels].

Abdominal ultrasound is an ideal screening method for pancreatic disease. Compared with CT and ERCP ultrasound is the best method for diagnosis of pseudocysts of pancreas. For chronic pancreatitis ERCP exceeds by far ultrasound.
