Since the publication of the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07), diagnostic criteria and severity assessment criteria for acute cholangitis have been presented and extensively used as the primary standard all over the world. However, it has been found that there are crucial limitations in these criteria. The(More)
BACKGROUND The Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07) were published in 2007 as the world's first guidelines for acute cholangitis and cholecystitis. The diagnostic criteria and severity assessment of acute cholecystitis have since been widely used all over the world. A validation study of TG07 has shown that the(More)
A positive correlation between absence of residual tumor at resection margins and long-term survival in the treatment of hilar bile duct carcinoma has encouraged some surgeons to use a more radical approach, including liver/portal vein resection and combined pancreatoduodenectomy. However, if liver resection is associated with significant morbidity and(More)
BACKGROUND/PURPOSE Both curative resection and minimized in-hospital mortality offer the only chance of long-term survival in patients with hilar cholangiocarcinoma. The reported resectability rates for hilar cholangiocarcinoma have increased by virtue of combined major hepatectomy, but this procedure is technically demanding and still associated with a(More)
PURPOSE To assess the diagnostic value of three-dimensional (3D) magnetic resonance (MR) cholangiopancreatography versus endoscopic retrograde cholangiopancreatography (ERCP) in various pancreaticobiliary diseases. MATERIALS AND METHODS Forty-six consecutive adult patients suspected to have extrahepatic biliary disease were examined. Breath-hold 3D(More)
BACKGROUND The Tokyo Guidelines for the management of acute cholangitis and cholecystitis were published in 2007 (TG07) and have been widely cited in the world literature. Because of new information that has been published since 2007, we organized the Tokyo Guidelines Revision Committee to conduct a multicenter analysis to develop the updated Tokyo(More)
BACKGROUND & AIMS Despite increasing use of various imaging examinations for non-invasive assessment of hepatic steatosis (HS), their relative accuracy is unknown. The objective of this study is to prospectively compare the accuracy of computed tomography (CT), dual gradient echo magnetic resonance imaging (DGE-MRI), proton magnetic resonance spectroscopy(More)
Recently, the phenomena of stochastic resonance (SR) have attracted much attention in the studies of the excitable systems under inherent noise, in particular, nervous systems. We study SR in a stochastic Hodgkin-Huxley neuron under Ornstein-Uhlenbeck noise and periodic stimulus, focusing on the dependence of properties of SR on stimulus parameters. We find(More)
This study presents our 14-year surgical experience with adult choledochal cyst disease (CCD), focusing on the clinical outcomes after surgical treatment. Medical records of 204 adult patients who had undergone surgery for CCD were reviewed retrospectively. Median patient age was 40.2 years, and 157 (77%) of the patients were female. Todani classification(More)
A considerable proportion of adult living donor liver transplantation (LDLT) recipients experience biliary complication (BC), but there are few reports regarding BC based on long-term studies of a large LDLT population. The present study examined BC incidence, risk factors and management using single-center data from 259 adult patients (225 right liver and(More)
