BACKGROUND AND AIMS Balloon enteroscopy-assisted ERCP has provided a marked improvement in the success rate of reaching the papilla and consecutive ERCP procedures in patients with surgically altered anatomy in the Roux-en-Y reconstruction setting. However, limited data are available on the outcome of balloon enteroscopy-assisted ERCP in patients with(More)
AIM To evaluate the safety and clinical application of high-intensity focused ultrasound (HIFU) therapy for unresectable pancreatic cancer (PC). METHODS Thirty PC patients (16 cases in stage III and 14 cases in stage IV) with visualized pancreatic tumors were admitted for HIFU therapy as an optional local therapy in addition to systemic chemotherapy or(More)
BACKGROUND There are currently no dedicated plastic stents for EUS-guided hepaticogastrostomy (EUS-HGS). OBJECTIVE We prospectively evaluated the feasibility and the technical and functional success rates of our newly designed plastic stent for EUS-HGS. DESIGN Prospective preliminary feasibility study. SETTING A tertiary-care referral center. (More)
BACKGROUND Minimally invasive interventions for choledocholithiasis are preferable in elderly patients because they tend to have multiple underlying disorders or a decreased activity of daily living. Endoscopic sphincterotomy and endoscopic papillary balloon dilation have been recognized as first-line treatments for choledocholithiasis excluding difficult(More)
A 66-year-old male with unbearable pruritus and jaundice was admitted for detailed examination. Blood tests on admission showed increased bilirubin with a dominant direct fraction. Ultrasonography and computed tomography performed subsequent to admission showed no narrowing or distension of the bile ducts. As the jaundice symptoms were not improved by the(More)
A 63-year-old woman was admitted to hospital with pain in the right lower quadrant. Abdominal computed tomography (CT) revealed a 60-mm cystic mass at a site corresponding to the appendix. The mass wall on the appendicular ostium was thickened and enhanced by contrast, while calcifi-cation was observed in the mass wall on the appendicular tip. No projection(More)
BACKGROUND AND OBJECTIVES There have been few studies to date evaluating the effectiveness of contrast-enhanced endoscopic ultrasound (CE-EUS) for detecting mural nodules in patients with branch duct-type intraductal papillary mucinous neoplasm (BD-IPMN) of the pancreas. We aim to evaluate the effectiveness of CE-EUS for detecting mural nodules in BD-IPMN.(More)
We have successfully developed a new methodology for the self-organization of C(60) molecules on the sidewall of carbon nanotubes for use in photoelectrochemical devices. Novel nanocarbon composites of fullerene (e.g., C(60)) and highly soluble, chemically functionalized single-walled carbon nanotubes (f-SWNT) have been prepared by the rapid injection of a(More)
