The advent of capsule endoscopy has revolutionized evaluation of the small bowel. Capsule endoscopy has become the criterion standard as the initial examination to diagnose small-bowel abnormalities, but does not allow for tissue sampling or therapeutic intervention. Deep enteroscopy can be performed by using a balloon-assisted device or a spiral overtube for both diagnostic and therapeutic interventions of the small bowel. Deep enteroscopy is time-consuming and requires special endoscopes an...
The duodenal-jejunal bypass liner (DJBL) is a new, device-based endoscopic treatment for type 2 diabetes mellitus (T2DM) and obesity.
EUS-guided FNA (EUS-FNA) has become the most efficacious way to obtain specimens from a solid lesion adjacent to the GI tract. Previous reports regarding the use of a stylet during EUS-FNA were all based on cytological diagnosis and have showed no significant superiority in terms of diagnostic yield.
Computer-aided diagnosis of EUS images was quite useful in differentiating pancreatic cancer from normal tissue and chronic pancreatitis. This study investigated the feasibility of using computer-aided diagnostic techniques to extract EUS image parameters to distinguish autoimmune pancreatitis from chronic pancreatitis.
Endoscopic transmural drainage of pancreatic pseudocysts (PPs) by using double-pigtail (DP) plastic stents requires placement of multiple stents and can be restricted by inadequate drainage and leakage risk. Recently, the use of fully covered self-expanding metal stents (FCSEMSs) has been reported as an alternative to DP plastic stents.
Studies comparing linear and radial EUS for the detection of pancreatic lesions in an asymptomatic population with increased risk for pancreatic cancer are lacking.
Large multicenter gastric cancer endoscopic submucosal dissection (ESD) studies conducted at major Japanese institutions have reported en bloc resection, en bloc tumor-free margin resection, and curative resection rates of 92.7% to 96.1%, 82.6% to 94.5%, and 73.6% to 85.4%, respectively, with delayed bleeding and perforation rates of 0.6% to 6.0% and 3.6% to 4.7%, respectively. Although ESD is currently an alternative treatment in some countries, particularly in Asia, it remains uncertain whe...
There are few data comparing endoscopic treatment outcomes for Barrett's esophagus (BE).
Reports on the performance of unsedated ultrathin endoscopy via the transnasal (uTNE) and transoral (uTOE) routes are conflicting. We aimed to estimate the technical success rate, patient preference, and acceptability of uTNE and uTOE alone and in comparison with conventional EGD (cEGD; with or without sedation).
This study aims to elucidate the exposure properties of nanoparticles (NPs; <100 nm in diameter) in semiconductor manufacturing processes. The measurements of airborne NPs were mainly performed around process equipment during fabrication processes and during maintenance. The number concentrations of NPs were measured using a water-based condensation particle counter having a size range of 10-3,000 nm. The chemical composition, size, and shape of NPs were determined by scanning electron micros...
