PURPOSE To evaluate the usefulness of percutaneous radio-frequency (RF) thermal ablation of nonresectable hepatocellular carcinoma (HCC) after occlusion of the tumor arterial supply. MATERIALS AND METHODS Sixty-two patients with cirrhosis and biopsy-proved HCC underwent RF ablation after interruption of the tumor arterial supply by means of occlusion of(More)
Hepatocellular carcinoma (HCC) is one of the most severe sequelae of chronic liver disease. The only potentially curative therapeutic options are surgical resection and orthotopic liver transplantation. In most HCC patients, however, at clinical presentation the tumors are unresectable because of multicentricity or poor hepatic functional reserve due to(More)
HISTORY AND CLINICAL FINDINGS Two patients were admitted to hospital for diagnosis of recurrent upper gastrointestinal bleeding. Both had chronic pancreatitis with alcohol abuse. Their general condition was satisfactory. Physical examination showed no diagnostic abnormalities other than mild epigastric pain on pressure in one patient. INVESTIGATIONS In(More)
The hepatopulmonary syndrome (HPS) is a reversible pulmonary insufficiency in association with liver disease, most frequently liver cirrhosis. The pathogenesis of HPS is poorly understood. HPS is characterized by arterial hypoxemia caused by intrapulmonary arteriovenous shunts or marked vasodilatation of the pulmonary vessels and ventilation-perfusion(More)
HISTORY AND CLINICAL FINDINGS Sclerotherapy was performed in a 52-year-old patient with alcoholic liver cirrhosis (Child-Pugh stage A) for recurrent bleeding from oesophageal varices. Half a year later he again was admitted to hospital because of recurrent passage of bloody stools. The cardiovascular status was stable; the liver was enlarged by 15 cm in the(More)
Several non-surgical local ablation methods for the treatment of hepatocellular carcinoma (HCC) have been developed. Among them, percutaneous ethanol injection is worldwide an accepted alternative to surgery in patients with small HCCs. Other local minimal-invasive treatment options, like one time radio-frequency thermal ablation seem to result in more(More)
BACKGROUND Crohn's disease and ulcerative colitis are chronic inflammatory bowel diseases of unknown etiology. Unspecific immunosuppressive therapy represents current standard treatment and is often associated with severe side effects. Several treatment regimens have been evaluated to identify alternative therapeutic options. Among these different diet(More)
Tumors of the papilla of Vater are very rare. Despite advanced imaging techniques the distinction between benign and malignant tumors remains very difficult. Because most ampullary and periampullary tumors are malignant, primary management is surgical. Here we report the case of a 65-year-old man with biliary obstruction caused by an ampullary hamartoma(More)
AIMS Although various methods of treatment have been tried, treatment options for advanced hepatocellular carcinoma (HCC) remain limited. Expression of the platelet-derived growth factor has been shown in HCC, which may derive from hepatic stem cells that express the c-kit proto-oncogene. Because of the promising results of imatinib and the key role played(More)
