Grading of difficulty is needed for laparoscopic liver resection (LLR). Indications for LLR are expanding worldwide from minor to major resections, particularly in institutions having surgeons with advanced skills. If the degrees of surgical difficulty were defined, it would serve as a useful guide when introducing LLR and stepping up to the more advanced(More)
Although carbon monoxide (CO) has been reported to protect against hepatobiliary dysfunction, mechanisms for its actions remain unknown. This study aimed to examine actions of physiologically relevant concentrations of CO on biliary excretion. The effects of transportal administration of CO on bile output and constituents were examined in perfused rat(More)
AIMS To evaluate the dynamics of Kupffer cell (KC) phagocytosis by performing both in vivo and in vitro studies using Sonazoid (GE Healthcare, Oslo) in a rat nonalcoholic steatohepatitis (NASH) model. METHODS Contrast enhanced ultrasonography (CEUS) was performed on a rat NASH model induced by a methionine choline deficient diet (MCDD) and control rats,(More)
OBJECTIVE To evaluate the gene expression signature of hepatocellular carcinoma (HCC) in relation to the gross morphology. BACKGROUND Eggel's nodular type of HCC is morphologically subclassified into the single nodular (SN) type, the single nodular type with extranodular growth (SNEG), and the confluent multinodular (CM) type, but their biomolecular(More)
Complete mobilization of the liver before parenchymal transection has been a standard approach during major hepatectomy. This safe approach is not always feasible for the cases in which it is difficult to mobilize the hepatic lobe involved by large tumors with diaphragmatic invasion. Recently, anterior approach for the right-sided hepatic resection was(More)
BACKGROUND & AIMS We previously identified that high Aurora B expression was associated with hepatocellular carcinoma (HCC) recurrence due to tumor dissemination. In this preclinical study, a novel inhibitor of Aurora B kinase was evaluated as a treatment for human HCC. METHODS AZD1152 is a selective inhibitor of Aurora B kinase. Twelve human HCC cell(More)
We report a case of serous cystadenoma of pancreas causing left-sided portal hypertension and gastric varices. A 68-year-old man was admitted for treatment of a pancreatic body tumor. Contrast-enhanced computed tomography (CT) showed a honeycombed cystic mass. A celiac angiogram showed a hypervascular tumor supplied mainly by a dilated splenic artery and(More)
Although Kupffer cells (KCs) may play a crucial role in post-cold ischemic hepatocellular injury, their role in nonnecrotic graft dysfunction remains unknown. This study examined reveal the role of KC in post-cold ischemic liver grafts. Rat livers treated with or without liposome-encapsulated dichloromethylene diphosphonate, a KC-depleting reagent, were(More)
BACKGROUND The link between microcirculatory disturbance and hepatocellular dysfunction remains unknown. The present study was designed to examine the key event of warm ischemia reperfusion (WIR) injury with subsequent cholestasis. METHODS A left lobar 70% ischemia and reperfusion rat model was used in this study. The portal vein and hepatic artery to the(More)
Increasing evidence suggests that cancers contain a small subset of cancer-initiating cells, so-called cancer stem cells (CSCs) that are capable of regenerating a tumor after chemoradiation therapy. Sphere forming ability is known to be one of properties of CSCs, but the significance remains unclear. The present study focused on sphere formation of human(More)
