BACKGROUND Endoscopic submucosal dissection (ESD) of early gastric cancer is less invasive than surgical resection, and if technically feasible, it may result in less long-term morbidity than does incisional surgery. However, ESD is technically difficult in patients who have had a previous distal gastrectomy. OBJECTIVE Our purpose was to retrospectively(More)
Biliary cannulation is the first step in therapeutic endoscopic retrograde cholangiopancreatography. This study aimed to evaluate unsuccessful cases of biliary cannulation in which the standard procedure was changed to a needle-knife precut papillotomy (NKPP), with particular attention given to postoperative anatomic factors. Between October 2002 and(More)
OBJECTIVE In Caucasian type 1 autoimmune hepatitis patients with a main susceptibility of human leukocyte antigen DR3 and DR4, elderly patients have a higher frequency of concurrent autoimmune disease and cirrhosis at presentation. However, in Japanese patients, the disease is dominantly associated with DR4, and their clinical features may be different from(More)
BACKGROUND In view of the recent advancement in endoscopic devices for biliary endoscopic intervention, the expert endoscopist can address complex morbidity. However, endoscopic 3-branched partial stent-in-stent deployment of metallic stents (MS) in patients with malignant hilar biliary stricture is technically demanding. OBJECTIVES To evaluate the(More)
Although needle-knife precut papillotomy (NKPP) is considered a useful alternative for achieving selective biliary cannulation, controversy remains regarding the technical proficiency needed to perform the procedure and its safety. This study evaluated whether procedural experience with NKPP predicted either successful cannulation or the development of(More)
BACKGROUND Platelet count has been shown to correlate with the hepatic fibrosis stage in chronic hepatitis C (CHC). The aim of the present study was to assess hepatic fibrosis progression or regression of CHC patients by long-term monitoring of the platelet count. METHODS A total of 429 interferon (IFN)-treated CHC patients were studied. Follow-up data on(More)
Lamivudine is widely used to treat patients with hepatitis B. However, the outcomes in patients with hepatocellular carcinoma (HCC) treated with lamivudine have not been established. This study was conducted to evaluate the outcomes of lamivudine treatment for patients with HCC using an untreated, matched control group. Thirty patients with controlled HCC(More)
Des-gamma-carboxyl prothrombin (DCP) is a well recognized tumor marker for hepatocellular carcinoma. Previously, we have demonstrated that DCP stimulates cell proliferation in hepatocellular carcinoma cell lines through Met-Janus kinase 1 signal transducer and activator of transcription 3 signaling pathway. In the present study, we demonstrated that DCP(More)
AIM In Caucasians in northern Europe and North America, type 1 autoimmune hepatitis is characterized by susceptibility to human leukocyte antigens DR3 and DR4, and patients with zone III necrosis more frequently have an acute onset of the disease and a lower frequency of cirrhosis than those without. In Japanese patients, however, type 1 autoimmune(More)
BACKGROUND Many patients with fulminant hepatic failure die before receiving liver transplantation because of the difficulty of pinpointing the suitable timing for liver transplantation. The revised King's College criteria are useful for patients with acetaminophen-related fulminant hepatic failure; however, in those with non-acetaminophen-related fulminant(More)
