[Non-parasitic splenic cysts].

Nonparasitic cysts of the spleen are uncommon and often result from blunt abdominal trauma. Nonsurgical management of blunt splenic injuries increases the number of observations of the post-traumatic cysts. Complications (infection, rupture and hemorrhage) are lifethreatening, difficult to diagnose and require urgent surgical management.

Correlations between sinusoidal pressure and liver morphology in cirrhosis.

Twenty-three patients with cirrhosis (alcoholic, post-hepatitic and cryptogenetic), who underwent hepatic venous catheterization and hepatic biopsy, were included in a histopathologic study to identify morphologic features correlated with the values of corrected sinusoidal pressure. The alterations in acinar architecture were investigated by histomorphometry and could be described as: a) multiacinar fibrosis with partial persistence of normal afferent and efferent vascular structures; b) complex acinar fibrosis with partial persistence of afferent structures alone; and c) simple acinar and subacinar fibrosis with almost complete disappearance of normal vascular structures. A significant negative correlation (p < 0.

[Radical surgery and loco-regional chemotherapy in the treatment of liver metastases of stomach and colorectal cancer].

The results of surgical treatment of hepatic metastasis from stomach and colo-rectal cancer in a series of 28 patients have been assessed. 21 cases were subjected to hepatic resection (stomach cancer: 7 cases; colorectal: 14 cases) and 7 underwent locoregional chemotherapy through the gastroduodenal artery with fully implantable catheters (stomach ca.: 1 case; colorectal ca.
