[Ultrasonography of the gallbladder and oral cholecystography. A prospective comparative study].

A prospective study comparing the information supplied by ultrasonography of the gallbladder and oral cholecystography was conducted in 254 patients with clinically suspected gallbladder calculi. The results demonstrated the limitations of cholecystography, notably the frequency of non-opacification in the absence of hepatic-biliary tract pathology and the possibility of false-negative results. Ultrasonography proved adequate in more than 80% of the cases and may be considered as the examination of choice for the diagnosis of biliary calculi. Its own limitations are discussed.

[Diagnostic value of ultrasonography in pancreatic duct dilatation. Results in 29 cases (author's transl)].

Results of diagnostic ultrasonography in 29 patients with pancreatic duct dilatation were able to define the value of this procedure in the diagnosis of chronic pancreatitis and particularly cancer of the pancreas. Dilatation of the duct may in fact be the only ultrasonographic sign of a pancreatic lesion. It is now possible to study the pancreatic duct by ultrasonography, and this method of exploration should be employed whenever the pancreas has to be investigated.

[Echogenic gallbladder sludge: ultrasonographic study and pathological significance in 74 cases (author's transl)].

Correlations between ultrasonographic and clinical and histological findings were studied in 74 patients presenting with echogenic gallbladder sludge. The majority of patients in whom bile examinations had been performed had either pus, blood, biliary sediment, or microcalculi in the bile, but precise identification of the nature of the sludge does not appear to be possible on ultrasonography. Calculi were present in the gallbladder in 39 p. cent of these patients, only 9 p. cent demonstrating the presence of sludge without established liver or biliary lesions. This ultrasonographic image appears, therefore, to be a clinically significant valid finding.

Vascular occlusive agents.

The authors have reviewed the experimental literature about the different agents used for endovascular embolization: clots, tissues, duramater, Gelfoam, oxydized cellulose, Ivalon, beads, microspheres, cyanoacrylates, silicone, barium. Each occlusive agent was studied in regard to its physical properties, injection methods, characteristics of obstruction, vascular reaction, and toxicity. The level and quality of obstruction obtained depend on many factors which are discussed.

[Ultrasonographic diagnosis of a left inferior vena cava with hemiazygos prolongation (author's transl)].

A case of a left inferior vena cava with prolongation into a hemiazygos vein is reported, in which the diagnosis was suspected after ultrasonography and confirmed by inferior cavography. Ultrasonographic signs were absence of a retrohepatic inferior vena cava, direct opening of the inferior hepatic veins into the right atrium, and the presence of a longitudinal vascular structure behind and on the left of the aorta, corresponding to the left inferior vena cava.

Computed tomography of hepatocellular carcinoma.

Computed tomography (CT) was used to evaluate 16 cases of hepatocellular carcinoma. CT identified and localized the tumor in 15 cases, an overall detection rate of 94%. The technique of dynamic CT scanning (rapid sequential scans after intravenous bolus of contrast medium), used in several cases, proved useful for determining patency of the portal vein and inferior vena cava and for demonstrating arteriovenous shunting due to tumor. CT detected some tumors missed by radionuclide scanning and arteriography. An approach to the diagnostic workup of patients with known or suspected hepatoma is presented, with a discussion of the roles of ultrasonography, radionuclide scanning, and arteriography.

[Computed tomography investigation of hepatic carcinomas (author's transl)].

Computed tomography examinations, using a second generation Acta 200 FS apparatus, were conducted on 28 occasions in 25 patients with hepatic carcinoma. Before injection, the tumor is usually of low density, to a small degree in many cases, and is heterogeneous and has indefinite limits. The sensitivity of the method is 96 p. cent. A precise study of the localization of the tumor was possible in only 11 cases, and a definite diagnosis was made in 64 p. cent. The method was only moderately effective in assessing the degree of regional extension. When compared with other methods for the investigation of the liver (scintigraphy, ultrasonography, arteriography), computed tomography shows no superiority over ultrasonography which should be employed for the initial examination.

[Obliteration of esophageal varices by percutaneous puncture of the left portal branch under "real time" ultrasonography (author's transl)].

Catheterization of the portal system by transhepatic percutaneous puncture may be difficult when atrophy of the liver, severe ascites, or thrombosis of the intrahepatic portal branches exists. It could be useful, in these cases, to employ "real time" ultrasonography to assist puncture of an intrahepatic portal branch. A case is reported in which this method was used to obtain percutaneous puncture of a left portal branch during obliteration of esophageal varices.

[Experimental endovascular electrocoagulation. Use of alternating current and a bipolar electrode (preliminary study) (author's transl)].

Early experimental studies have shown that it is possible to obtain vascular obliteration and clot formation using monopolar direct current electrocoagulation. There is a major risk of rupture of blood vessels if alternating current is used. Using a co-axial bipolar electrode and high frequency alternating current it was possible to obtain valid, reproducible, and safe vascular obliteration in the distal digestive tract arteries in dogs. The obliteration is due to lesions of the intima and the formation of a clot in situ.

Angiographic study of renal vein involvement in renal cell carcinoma.

High dose selective renal arteriography was performed in 62 cases of renal cell carcinoma to study the patency of the renal vein trunk. Arteriographic findings were correlated with histopathology in all cases. In 35 cases of angiographic patency of the renal vein surgery always confirmed the findings. 11 false positive results were observed (the arteriographic diagnosis of venous involvement was not found at surgery). The authors believe that this method is easy and reliable; inferior cavagraphy is not necessary when arteriography shows the patency of the vein.
