Rupture of splenic angiosarcoma: a rare cause of spontaneous haemoperitoneum

Primary splenic angiosarcoma, a very rare mesenchymal tumour of endothelial cell origin, comprises 2.6% of all cases of angiosarcoma and 10% of all primitive splenic tumours. Clinical presentation is usually unspecific, with abdominal pain and anaemia. Rupture is a rare complication and should prompt emergency splenectomy. Prognosis is usually poor because of liver, lung or bone metastases. We describe the case...

Study of hepatocellular function in the murine model following hepatic artery s...

PURPOSE: To investigate the impact of selective hepatic artery clamping (SHAC) in hepatocellular function. METHODS: Three groups of Wistar male rats were subjected to SHAC ischemia period of 60min: Group A continuous SHAC were subjected to SHAC ischemia period of 60min, Group B intermittent SHAC of 30min with 5min of reperfusion and Group C intermittent SHAC of 15min with 5min of reperfusion. Animals without SH...

Perioperative tumor cell dissemination in patients with primary or metastatic c...

INTRODUCTION: Although there is general correlation between the TNM stage of colorectal cancer (CRC) and its prognosis, there is often significant variability of tumor behaviour and individual patient outcome, which is unaccounted for by pathologic factors alone. Our aim was to estimate perioperative tumor cell dissemination in patients with primary or CRC liver metastases as a possible factor influencing the o...

Intermittent Pringle Maneuver and Hepatic Function: Perioperative Monitoring by...

BACKGROUND: Intermittent Pringle maneuver or selective portal clamping often are used to control inflow during parenchymal liver transection. This study was designed to determinate whether these maneuvers are associated with adverse hepatic function. METHODS: Resection was performed without portal clamping in 17 patients (group 1). Selective continuous portal clamping was performed in 11 patients (group 2) and ...

The influence of selective clamping of the elements of hepatic pedicle in the hepatocellular function and viability were evaluated in our department. AIM: Study the effect of selective clamping of the portal vein (CPV) in hepatocellular function in an animal model with normal liver. METHOD: Three groups of Wistar rats (males, 2 months) were subjected a CPV for 60 min: group A (n=21) submitted to a continuous ...

Treatment of tumour recurrence after resection of hepatocellular carcinoma. Ana...

OBJECTIVE: To evaluate the long-term results of aggressive treatment of HCC recurrence. METHODS: Two hundred and nine consecutive patients underwent hepatic resection for HCC in our hospital. Tumour recurrence was diagnosed in 97 (51%) of the 190 patients with curative resection. Sixteen underwent hepatic resection: two right hepatectomies, one three-segmentectomy, one left hepatectomy, five two-segmentectomies...

Nesidioblastose do adulto

In adults, endogenous hyperinsulinemic hypoglycaemia is almost invariably due to insulinoma. The authors describe a 29 year old patient with repeated postprandial symptomatic hypoglycaemias and negative prolonged fast test. Distal pancreatectomy was performed, directed by positive arteriographic testing. Histological examination revealed pancreatic nesidioblastosis and no tumoral lesion. Distinct pathogenetic, ...
