BACKGROUND Hepatocellular carcinoma (HCC) arising in normal liver parenchyma is rare and the outcome after hepatectomy is not well documented. METHODS Between June 1998 and September 2003, 33 patients without viral hepatitis underwent resection for HCC in a non-cirrhotic, non-fibrotic liver. Data were analysed with regard to operative details,(More)
Bile duct injury is a severe and potentially life-threatening complication of laparoscopic cholecystectomy. Several series have described a 0.5% to 1.4% incidence of bile duct injuries during laparoscopic cholecystectomy. The aim of this study was to report on an institutional experience with the management of complex bile duct injuries and outcome after(More)
OBJECTIVE To describe a large single-center experience with hepatic resection for metastatic leiomyosarcoma. SUMMARY BACKGROUND DATA Liver resection is the treatment of choice for hepatic metastases from colorectal carcinoma. In contrast, the role of liver resection for hepatic metastases from leiomyosarcoma has not been defined. METHODS The records of(More)
The role of liver biopsy (LB) in donor selection for adult living donor liver transplantation remains controversial, since the procedure is associated with additional potential risks for the donor. From April 1998 to August 2004, 730 potential living donors for 337 adult recipients underwent our multistep evaluation program. In 144 candidates, LB was(More)
OBJECTIVE To evaluate the role of extended hepatectomy in locally advanced intrahepatic cholangiocarcinoma (ICC). SUMMARY BACKGROUND DATA ICC is a rare tumor which has to be clearly distinguished from hepatocellular carcinoma and extrahepatic bile duct carcinoma. It is believed that long-term survival can only be achieved by surgical resection. METHODS(More)
HYPOTHESIS Currently, standard planning for hepatic resection is based on the schematic description of the functional anatomy of the liver according to Couinaud, and on the evaluation of 2-dimensional computed tomographic imaging of the liver. Recent developments in image-based computer assistance allow patients' individual functional liver anatomy to be(More)
The pig is a common large animal for experimental settings in many fields of surgery. In experimental surgery, there is a need for different narcotic procedures depending on the complexity of the surgical investigation. Narcotic procedures have to be safe, easy to handle, and should not influence the experimental results. We hereby present important aspects(More)
We have constructed a bioreactor aimed at imitating the three-dimensional micro- and macroenvironment of the liver. In vivo hepatocytes are arranged in plates of cell monolayers and are specifically attached with both sinusoidal surfaces to the space of Disse which contains extracellular matrix. Nonparenchymal cells are located on the other side of the(More)
Models for cocultures of parenchymal (PC) and nonparenchymal cells (NPC) of the liver relied on mixing the cells in a two-dimensional configuration or on establishing spheroidal aggregates. In vivo hepatic nonparenchymal cells, such as endothelial cells and Kupffer cells, are separated from parenchymal cells by extracellular matrix (ECM). Due to their(More)
1. The aim of the study was the development of a small-scale liver cell bioreactor maintaining tissue monoxygenase activity and hepatospecific activities over at least 2 weeks. 2. For characterization the antihypertensive drug urapidil was used as a model compound to study maintenance of metabolic activity. Tissue-specific parameters assessed included urea(More)
