Despite the development of peroral video cholangioscopy (PVCS), no prospective multicenter studies have been undertaken to investigate diagnostic accuracy PVCS in biliary tract diseases. Therefore, aim this study was clarify evaluating lesions.This a at five tertiary referral centers Japan and included 87 eligible patients with diseases who underwent PVCS. The evaluated ability diagnose indeterminate diseases, detect mucosal cancerous extension preoperatively extrahepatic bile duct cancers,...
Background and Study Aims: Gastric carcinoid tumors are a rare disease. Previously, total gastrectomy was regarded as the treatment of choice. However, differences in biological malignancy have recently led to increased use endoscopic mucosal resection (EMR) for treatment. We studied outcome EMR patients with gastric carcinoids who were treated at our hospital discuss indications Patients Methods: Between 1986 1999 we carried out five tumors. The procedure used either strip biopsy or...
The impact of somatostatin receptor type 2 (SSTR-2a) expression levels on outcomes in patients with pancreatic neuroendocrine tumors (PNETs) has not been evaluated.Correlations between clinicopathologic characteristics, including SSTR-2a and outcomes, were retrospectively studied 79 (PNETs).The score was 0 27% patients, 1 24% 3 30% 4 18% patients. overall survival rate 87% at year, 77% years, 71% 5 years. On univariate analysis, a tumor that measured ≥ 20 mm greatest dimension, stage IV...
Aim: A number of potential variables are associated with the diagnostic accuracy endoscopic ultrasonography‐guided fine‐needle aspiration (EUS‐FNA). The aim this study was to evaluate factors affecting EUS‐FNA for upper gastrointestinal submucosal or extraluminal solid lesions. Methods: Patients such lesions who underwent between January 2009 and December 2010 were studied retrospectively. Needles 22, 25 19 gauge used. associations results as mass location, size, needle passes, combined...
In order to investigate the behavior of rare earth elements (REEs) and uranium (U) in marine organism, concentrations REEs U some brown algae samples taken on coast Niigata Prefecture were determined. addition, laboratory model experiment uptake these using living dried (Undaria pinnatifida Sargassum hemiphyllum) was also carried out survey bioaccumulation mechanism algae. Consequently, following matters have been mainly clarified. (1) The concentration for each organ hemiphyllum is "main...
In order to investigate the behavior, distribution, and characteristics of heavy metals including rare earth elements (REEs), thorium (Th), uranium (U) in sludge, total fractional concentrations these sludge collected from an industry water treatment plant were determined compared with those natural soil. addition, removal/recovery process (Pb, Cr, Ni) polluted was studied biosurfactant (saponin sophorolipid) elution by batch column experiments evaluate efficiency for removal metals....
To date, only limited evidence has supported the notion that resistance exercise positively impacts non-alcoholic fatty liver disease. We evaluated effects of on metabolic parameters disease (NAFLD) in 53 patients who were assigned to either a group performed push-ups and squats 3 times weekly for 12 weeks (exercise group; <i>n</i>=31) or did not (control; <i>n</i>=22). Patients control proceeded with regular physical activities under restricted diet throughout study. The compared between 2...
To investigate the efficacy of continuous regional arterial infusion (CRAI) a protease inhibitor and antibiotic for severe acute pancreatitis (SAP) in patients admitted to an intensive care unit (ICU). A total 51 with SAP requiring admission ICU were studied. The divided into two groups: one received nafamostat mesylate imipenem by (CRAI group) other inhibitors antibiotics intravenous (non-CRAI group). evaluate therapeutic usefulness CRAI SAP, rate surgery cumulative survival compared...
Background and Aim Endoscopic retrograde cholangiopancreatography ( ERCP ) is technically challenging in patients with R oux‐en‐ Y anastomosis B illroth‐ II anastomosis. Short‐type single‐balloon enteroscope SBE was developed to carry out postoperative a reconstructed intestine. It useful because of its good rotational straightening ability the availability various conventional accessories through 3.2‐mm working channel, it has water‐jet channel. Methods In present study, we compared...
An experiment on the adsorption of uranium (VI) by chitosan was conducted to investigate efficiency as an adsorbent for U(VI). The potential U(VI) investigated with ICP-MS varying experimental conditions such pH in order obtain optimum conditions. Adsorption dependence confirmed, and highest uptake observed at 5. In addition, scrutinize results, quantum chemistry calculations were performed. taking into account conditions, show that increases total charge adsorbate species decreases if both...
Balloon enteroscopy-assisted ERCP (BE-ERCP) has become the first-line therapy for biliopancreatic anastomotic strictures. However, it is not always successful, and salvage methods have been established. This study aimed to evaluate outcomes of EUS-guided transanastomotic drainage using a forward-viewing (FV) echoendoscope.Of eight cases wherein BE-ERCP treatment failed due severe or complete benign stricture, seven underwent choledochojejunostomy, pancreaticojejunostomy was applied in one...
In stereomicroscopic sample isolation processing, the cutoff value (≥4 mm) of stereomicroscopically visible white cores indicates high diagnostic sensitivity. We aimed to evaluate endoscopic ultrasound-guided tissue acquisition (EUS-TA) using a simplified on-site evaluation upper gastrointestinal subepithelial lesions (SELs).
<b>Background and study aims:</b> Recent progress in chemotherapy has prolonged the survival of patients with malignant biliary strictures, leading to increased rates stent occlusion. Occlusion covered metallic stents now occurs about half all strictures. The removal followed by placement a second been attempted, but outcomes remain controversial. aim current was evaluate effectiveness safety primary secondary (re-intervention) assess feasibility removal. <b>Patients methods:</b> included...
BACKGROUND: Various factors, such as the optimal number of passes, aspiration pressure, and use 19-gauge Trucut biopsy needles, have been studied to improve diagnostic accuracy endoscopic ultrasound-guided fine-needle (EUS-FNA). We retrospectively compared EUS-FNA between 25- 22-gauge which widely used recently. SUBJECTS AND METHODS: The study group comprised 47 consecutive patients who underwent with both 22- 25-gauge needles from October 2007 through March 2010. Their underlying diseases...
A prototype forward-viewing instrument has been developed for therapeutic endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA). We had the opportunity to use this echo endoscope and study its clinical usefulness, mainly diagnostic EUS-FNA.The was used 15 months between November 2006 March 2010, in a group comprising 47 consecutive patients. Diagnostic EUS-FNA done 38 patients accuracy of device compared with that from an oblique-viewing reference who were matched by disease...
The adsorption capacity of activated carbon modified with potassium permanganate (KMnO4) for rare earth elements (REEs) from aqueous solution was investigated. characterized by SEM (scanning electron microscopy), FT-IR (Fourier transform infrared spectrometer), and N2 adsorption-desorption tests. Adsorption experiments solutions containing known amounts some REEs (i.e. La, Lu, Yb, Eu, Y, Sc) onto the were explored in a batch system. amount adsorbed at different pH values, initial...
