Although preoperative biliary drainage in jaundiced patients is controversial, external biliary drainage (EBD) is beneficial for infection control in patients with biliary cancers. When EBD is performed, additional bile replacement (BR) has the benefit of improving impaired intestinal barrier function, but the detailed mechanism remains unknown. We examined(More)
INTRODUCTION Laparoscopic cholecystectomy (Lap-C) is a standard surgery for symptomatic gallbladder stones and acute or chronic cholecystitis. Resident surgeons often perform this operation early in their training, but they sometimes encounter difficulties for various technical reasons. Although encountering a gallbladder buried deep within the gallbladder(More)
Lack of effective adjuvant therapy against advanced extrahepatic biliary tract carcinoma (BTC) requires that new therapeutic methods, such as molecular targeted therapy, be developed. The mitogen-activated protein kinase (MAPK) and Akt signaling pathways, which activate cell proliferation and suppress apoptosis, respectively, may function as important(More)
Allergic inflammation in the airway is generally considered a Th2-type immune response. However, Th17-type immune responses also play important roles in this process, especially in the pathogenesis of severe asthma. IL-22 is a Th17-type cytokine and thus might play roles in the development of allergic airway inflammation. There is increasing evidence that(More)
Pancreaticobiliary maljunction (PBM) arises from a developmental abnormality during the embryonic period; thus, these patients may have anatomical variations of the liver blood supply, including aberrant vessels and unusual locations. We reviewed retrospectively the vascular anatomy of 52 patients with PBM, who were seen between 1998 and 2013. There were 11(More)
We assessed the predictive value of the preoperative neutrophil-to-lymphocyte ratio (NLR) in patients who underwent a two-stage treatment combining reductive surgery and percutaneous isolated hepatic perfusion for multiple hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). Forty-two patients underwent the two-stage treatment between(More)
Allergic inflammation in the airway is generally considered a Th2-type immune response. However, recent studies demonstrated that Th1- and Th17-type immune responses also play important roles in this process. IFN-gamma is a Th1-type cytokine that generally counteracts the Th2 response. Although previous studies suggest that exogenous IFN-gamma suppresses(More)
Hepatocyte growth factor (HGF) has an important role in many biological events such as angiogenesis and cell proliferation, as well as anti-fibrotic and anti-apoptotic effects. In addition, we found that HGF suppresses antigen-induced immune responses in the airway by suppressing dendritic cell functions, using a HGF-producing plasmid vector. In the present(More)
A 69-year-old man diagnosed as having gallbladder cancer with liver invasion and metastasis to Couinaud's hepatic segment 8 (S8) was referred to our hospital. Because of the presence of liver metastasis, gemcitabine administration was chosen. Although gemcitabine was effective for the liver metastasis, his serum carcinoembryonic antigen (CEA) level had(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is now considered a chronic inflammatory disease. Although dendritic cells (DCs) are thought to play a key role in immune responses, studies investigating the role of DCs in COPD are quite limited. METHODS Porcine pancreas elastase was intratracheally administered to C57BL/6J mice on day 0. On days(More)
