Cystic lesion of the kidney with ultrastructural evidence of mesothelial origin.

A case of cystic renal mesothelioma in a 55 year-old woman is described. The patient had only intense pain in the left lumbar region. The tumor macroscopically appeared as a cystic multilocular mass, 20 cm. in diameter, sharply demarcated from the renal parenchyma. A light and electron microscope study was performed, and strongly supported mesothelial origin. The patient was treated by surgical therapy which was completely resolutive. The differential diagnosis between this tumor and peri and para-renal cystic lesions is discussed.

Study of the hemocoagulative parameters in hemoperfusion on polymer coated resins.

A hemoperfusion column containing anionic exchange resin coated with a new polymer has been tested in vivo for blood compatibility. The hemocoagulative parameters, evaluated before and after the cartridge during hemoperfusion, did not show any significant alteration even as regards the number and the functionality of the platelets nor as regards a possible activation of the fibrinolysis process. On the basis of these results, the hemoperfusion system examined can be regarded as hemocompatible from the hemocoagulative standpoint.

[Intraoperative echography in biliopancreatic surgery].

Intraoperative sonography (I.O.S.) with the use of high-frequency probes placed in direct contact with structures in exploration assures a more diagnostic accuracy. I.O.S. is particularly useful in bilio-pancreatic surgery for a more precise diagnostic valuation and an excellent surgical approach. It is fundamental in the lithiasis of the biliary duct, especially hepatic lithiasis, microlithiasis, obstruction of common bile duct of uncertain cause and during laparocholecystectomy. In pancreatic surgery I.O.S. is of great usefulness in the study of acute and chronic pancreatitis and their complications, cysts, pseudocysts and cystic tumors. I.O.S. plays important role both in exocrine pancreatic carcinomas for a correct staging, and resectability decision, and in endocrine functioning tumors, permitting the location of some lesions of little dimension and eventual hormone secreting hepatic or lymph nodal metastases. In laparoscopic mini-invasive surgery, I.O.S. substitutes the palpatory sense of touch in the location and study of anatomic structures, reducing the risks of iatrogenic lesions and allowing, diagnostic accuracy even in some underestimated pathologies.

Cystic lymphangioma of the pancreas: anatomoclinical, diagnostic and therapeutic considerations regarding three personal observations and review of the literature.

Cystic lymphangioma is a very rare pathology and the pancreatic ones represent an exceptional report that must be considered in the differential diagnosis with others and more frequent cystic lesions of the pancreas. In this paper we describe three cases of cystic lymphangiomas of the pancreas observed in our Institute and we report on the literature review. Anatomopathological, clinical and therapeutics aspects of pancreatic cystic lymphangioma were analyzed for a better knowledge of this cystic lesion and to recognize some specific findings that could allow a preoperative diagnosis and, subsequently, a proper treatment.

[Acute experimental hepatic insufficiency in pigs. Validity of a model with biohumoral and electroencephalographic monitoring].

Effectiveness of surgically induced acute hepatic failure in pig and most suitable time to apply artificial support in hepatic coma are evaluated in this work. Five male pigs weighing about 30-35 kg are employed. Latero-lateral porto-caval shunt was performed; the vascular disconnection of liver was obtained by ligature of blood vessels. Ligature was also placed on main biliary way after cholecistectomy. Blood samples were obtained (at 0, 1, 2, 6, 12, 18, 24 hours) to essay serum bilirubin, alkaline phosphatase and GOT-GPT levels as index of cholestasis and necrosis. Porto-caval encephalopathy was evaluated by means of serum ammonium levels, aminoacid pattern and E.E.G. Serum aminoacid pattern was carefully determined; its changes were found similar in man during coma. All pigs died 24-36 hours after surgery with liver ischemic and necrosis. Clinical and laboratory data obtained in experimental conditions were found similar to picture of acute hepatic failure in man, confirming validity of our model.
