[Sclerosing peritonitis. A complication of LeVeen peritoneovenous shunt].

Sclerosing peritonitis (abdominal cocoon syndrome) is a rare chronic affection of the peritoneum; its etiology is multifactorial and it affects all ages. Capsulating membranes seem to grow from a poorly cellular connective deposition in many layers on the intestinal peritoneum and are casually detected by surgery or autopsy. The placement of the peritoneovenous shunt can favour the deposition of fibrin on the visceral peritoneum, determining the formation of sclerosing membranes.

[Sertoli cell tumor. Case report].

[Cholangiojejunostomy of the duct of the 3d segment. Palliative treatment of cholestatic jaundice caused by neoplastic obstruction of the hepatic hilus].

Cholangiojejunostomy of the duct of the III segment in the palliative treatment of mechanical jaundice from neoplastic obstruction of the hepatic hilus. The neoplastic obstruction of the liver hilus has an almost total absence of forewarning clinical signs and therefore results in surgery at a late stage when the patient is not susceptible to radical treatment. It is therefore necessary to use palliative treatment in order to resolve the serious jaundice, the main cause of a quick death.
