BACKGROUND Lethal pancreatitis has been reported after treatment for common bile duct stones using small endoscopic papillary balloon dilation. METHODS We retrospectively evaluated the safety and efficacy of using large balloon dilation alone without the use of sphincterotomy for the treatment of large common bile duct stones in Kaohsiung Veterans General(More)
BACKGROUND & AIMS beta-blockers and banding ligation are effective in the prevention of variceal rebleeding. However, the relative efficacy and safety remains unresolved. METHODS One hundred twenty-one patients with a history of esophageal variceal bleeding were enrolled. Patients were randomized to undergo regular endoscopic variceal ligation (EVL group,(More)
BACKGROUND & AIMS The generation of oxidative stress and transforming growth factor beta1 (TGF-beta1) production play important roles in liver fibrogenesis. We have previously shown that hepatitis C virus (HCV) increases hepatocyte TGF-beta1 expression. However, the mechanisms by which this induction occurs have not been well studied. We explored the(More)
BACKGROUND Endoscopic methods are currently the treatment of choice for patients with common bile duct (CBD) stones, but subsequent management of the intact gallbladder for patients following endoscopic treatment is still controversial. The primary aim of this study was to discover the association between gallbladder status and recurrent biliary(More)
BACKGROUND Rapid virological response (RVR) strongly predicts sustained virological response (SVR) in patients with chronic hepatitis C (CHC), and abbreviates antiviral therapy in some patients. OBJECTIVES To identify factors predicting virological relapse (VR) in CHC patients who attained RVR. PATIENTS AND METHODS Medical records of 133 CHC patients(More)
OBJECTIVE In patients with cirrhosis and spontaneous bacterial peritonitis (SBP), the use of intravenous albumin has been shown to prevent deterioration of renal function and to decrease the mortality rate, but the mechanisms remain unclear. The purpose of this study was to characterize the mechanisms of action of albumin with the focus on endotoxin and(More)
This paper presents a framework of simulation environment (SEMU) which allows developers to understand the behavior of applications or protocols for a wireless sensor network (WSN) before deploying real nodes in a physical environment. For eliminating the gap between simulation and real deployment, SEMU has supported fast real code emulation by dynamic(More)
AIM To evaluate the factors affecting the early tumor recurrence within one year in cirrhotic patients having a single small hepatocellular carcinoma (HCC) after complete tumor necrosis by radiofrequency ablation (RFA) therapy. METHODS Thirty patients with a single small HCC received RFA therapy by a RFA 2000 generator with LeVeen needle. Tri-phase(More)
BACKGROUND Rebleeding occurs in 10% to 30% of bleeding ulcer patients receiving endoscopic epinephrine injection therapy. It remains unclear whether addition of a secondary clip therapy following epinephrine injection may reduce the rebleeding rate of high-risk bleeding ulcers. OBJECTIVE To compare the efficacies of epinephrine injection alone and(More)
BACKGROUND A wide array of proteins is secreted into the bile and may be associated with biliary tract diseases. We attempted to discover novel biomarker in bile for cholangiocarcinoma. METHODS Bile was collected from patients with bile duct obstruction. Proteins were separated by 2-dimensional electrophoresis and identified by mass spectrometry. Levels(More)
