BACKGROUND We aimed to clarify the clinical benefits of using 8-mm versus 10-mm diameter self-expandable metallic stent (SEMS) in bilateral endoscopic stent-in-stent (SIS) deployment for malignant hilar biliary obstruction (MHBO). METHODS A total of 72 consecutive patients with MHBO treated by endoscopic bilateral SIS deployment were enrolled. The 8-mm(More)
The relationship between Helicobacter pylori (H. pylori) and gastric diseases (e.g. peptic ulcer, MALT lymphoma, and stomach cancer) has been widely accepted. Recent studies have also suggested an association between H. pylori infection and idiopathic thrombocytopenic purpura (ITP). In this study, an H. pylori eradication treatment was administered to 20(More)
raphy from the major duodenal papilla, the DPD appeared via the loop-forming communicating duct called the ansa pancreatica (Fig. 1A). Next, the VPD ascended making a loop cranially, and it joined the DPD again (Fig. 1B). A cyst was enhanced through the DPD. Pancreatography from the minor duodenal papilla showed the entirely dilated DPD and the VPD. A(More)
Despite progress in clinical cancer medicine in multiple fields, the prognosis of pancreatic cancer has remained dismal. Recently, chemopreventive strategies using phytochemicals have gained considerable attention as an alternative in the management of cancer. The present study aimed to evaluate the chemopreventive effects of resveratrol (RV) and apocynin(More)
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is frequently performed for the diagnosis and treatment of type 1 autoimmune pancreatitis (AIP). However, the prevalence of ERCP-related adverse events in patients with type 1 AIP has not been evaluated. We aimed to clarify the feasibility of ERCP in patients with type 1 AIP. METHODS We(More)
Locus and chromosome abnormalities have not been well clarified in intraductal papillary mucinous neoplasms (IPMNs). The aim of this study was to retrospectively examine these abnormalities using fluorescence in situ hybridization. IPMNs (n=28) were histopathologically classified into noninvasive IPMN (n=17) and IPMN with an associated invasive carcinoma(More)
BACKGROUND AND AIMS The clinical features of acute obstructive suppurative pancreatic ductitis (AOSPD) have not been elucidated. We aimed to clarify the clinical features of AOSPD. METHODS We retrospectively reviewed the clinical features of 20 patients with AOSPD at two tertiary referral centers between 1993 and 2012. We compared 17 AOSPD patients with(More)
Ectopic adrenocorticotropic hormone (ACTH) is rarely secreted by neuroendocrine tumors. Although neuroendocrine tumors may occur at any site in the gastrointestinal system, they very rarely occur in the ampulla of Vater and have a poor prognosis. The present study described the first Cushing's syndrome as a result of ectopic ACTH arising from the ampulla of(More)
IgG4-related sclerosing cholangitis (IgG4-SC) and primary biliary cirrhosis (PBC) can both cause liver dysfunction. While IgG4-SC is associated with IgG4-related diseases such as autoimmune pancreatitis, PBC is associated with various autoimmune diseases. However, there is only one case report of an association between IgG4-SC and PBC, and this association(More)
