OBJECTIVE To assess the clinical benefits of preoperative endoscopic nasobiliary drainage (ENBD) in patients with perihilar cholangiocarcinoma. BACKGROUND The advantages of ENBD have been previously reported. However, no studies to date have examined a large number of patients, including those with Bismuth-Corlette (B-C) type III to IV tumors. In(More)
BACKGROUND Pancreatic endocrine tumors (PETs) develop in relatively few patients, but they are often difficult to diagnose because of their small size and various clinical symptoms. OBJECTIVE The aim of this study was to investigate the usefulness of EUS combined with contrast enhancement (CE-EUS) in the preoperative localization of PETs and the(More)
OBJECTIVES The natural history of branch duct-type intraductal papillary mucinous neoplasms (BD-IPMNs) of the pancreas remains unclear. We conducted a retrospective long-term follow-up study for malignant transformation (MT) of BD-IPMNs focusing on morphological changes. METHODS The subjects consisted of 142 patients who underwent contrast-enhanced(More)
OBJECTIVES Dendritic cell (DC) therapy frequently induces a measurable immune response. However clinical responses are seen in a minority of patients, presumably due to insufficient expansion of antigen-specific cytotoxic T lymphocytes (CTLs) capable of eradicating tumor cells. To increase therapeutic efficacy of DC-based vaccination, we have undertaken the(More)
BACKGROUND AND AIM Although peripancreatic vascular lesions are occasionally encountered in autoimmune pancreatitis (AIP), there are few reports focusing on these involvements. We aimed to investigate the peripancreatic vascular involvements associated with AIP. METHODS We retrospectively analyzed 54 AIP patients who met the International Consensus(More)
BACKGROUND An accurate diagnosis of pancreatic fibrosis is clinically important and may have potential for staging chronic pancreatitis. The aim of this study was to diagnose the grade of pancreatic fibrosis through a quantitative analysis of endoscopic ultrasound elastography (EUS-EG). METHODS From September 2004 to October 2010, 58 consecutive patients(More)
BACKGROUND AND AIM Intraductal papillary mucinous neoplasms (IPMNs)have a wide pathologic spectrum and it is difficult to differentiate malignant from benign tumors. The aim of this study was to identify predictors of malignancy using contrast-enhanced endoscopic ultrasound (CE-EUS). SUBJECTS AND METHODS In our institute, main duct type and mixed type(More)
BACKGROUND Small-bowel tumors (SBTs) represent a diagnostic challenge. OBJECTIVE To evaluate the usefulness of contrast-enhanced CT (CECT), fluoroscopic enteroclysis (FE), videocapsule endoscopy (VCE), and double-balloon endoscopy (DBE) and the outcome after treatment. DESIGN Single-center, retrospective study. SETTING Tertiary-care referral hospital.(More)
Contrast-enhanced endoscopic ultrasonography (CE-EUS) and EUS-elastography are cutting-edge diagnostic modalities for pancreatic disorders. Each pancreatic disorder has characteristic hemodynamics. CE-EUS uses color Doppler flow imaging to classify pancreatic lesions into a spectrum of solid and cystic patterns. Although there is overlap in the patterns(More)
The aims of this study were to compare the detection rates of gastrointestinal follicular lymphoma lesions by video capsule endoscopy (VCE) and double-balloon endoscopy (DBE), and to determine the pathologic diagnostic yields of DBE-directed biopsies. A total of 27 consecutive patients were enrolled. No significant difference in detection rates was observed(More)
