Endoscopic Ultrasound-Guided Hepaticogastrostomy With Plastic Stent Versus Metallic Stent for Malignant Biliary Obstruction: A Meta-Analysis.

OBJECTIVES Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an alternative procedure for malignant biliary obstruction after failure of endoscopic retrograde cholangiopancreatography. When performing EUS-HGS, either plastic or metal stents are used, but selection often depends on the discretion of the endo...

Experimental Evaluation of Novel Two-Dimensional Endoscopic Ultrasound Shear Wave Elastography: A Phantom-Based Study.

Point shear wave elastography (SWE) can indicate tissue elasticity using absolute values, but it remains difficult to determine which areas are suitable for measurement. Recently, two-dimensional endoscopic ultrasound SWE (2D-EUS-SWE), which allows visual assessment of appropriate measurement locations, has become poss...
