We report a patient with cirrhosis and hepatopulmonary syndrome. This syndrome is an entity characterized by anomalies in the arterial oxygenation in patients with chronic hepatic disease and/or portal hypertension and demonstration of pulmonary vasodilatation (PV) in absence of primary cardiac or pulmonary disease. We show that the finding of PV with(More)
We have prospectively studied the evolution of 13 patients with liver hydatid cysts treated with mebendazole. Two patients also had peritoneal hydatid disease in addition to liver cysts. One of the two also had a retrovesical cyst. Liver cysts disappeared in three patients. In one, the liver cyst reappeared and in another a new cyst was observed after(More)
Of the 18 endoscopic sphincterotomies performed on 18 cirrhotic patients for choledocholithiasis, a mortality rate of 16.6% was registered. However, this figure can be limited to 6.6% if we take only successful sphincterotomies (15/18, 83.3%) into account. After closely reviewing relevant literature, it would appear that operative mortality in comparable(More)
Adrenal neoplasm is a rare cause of Budd-Chiari syndrome. We report a case of fulminant acute Budd-Chiari syndrome due to inferior vena cava thrombosis stemming from invasion by a clinically nonfunctioning adrenal neoplasm. We also review briefly the clinical characteristics of the seven previously reported cases.
We review standard management for patients with gallstones and common duct stones in the light of endoscopic sphincterotomy. As the sole treatment that procedure needs to be compared to surgical approaches, but now that laparoscopic cholecystectomy is available, there is some uncertainty about which surgical option should stand in comparison. We review(More)
OBJECTIVE gas exchange abnormalities are frequent in cirrhosis. These abnormalities can be considered an indication or contraindication for liver transplantation. The aim of this study was to investigate the etiology and frequency of these alterations. METHOD seventy-eight patients with cirrhosis and 20 healthy subjects were selected randomly. Arterial(More)
BACKGROUND/AIMS The use of transesophageal contrast echocardiography (TOCE) in the diagnosis of intrapulmonary vascular dilatation (IVD) and hepatopulmonary syndrome (HPS) needs to be studied. We tested the specificity of TOCE using traditional criteria and the value of a new method based on TOCE, a grading scale and a selected contrast. METHODS 1)(More)
