Endoscopic retrograde cholangiography (ERCP) is widely used as a first-line therapy for biliary drainage. ERCP occasionally fails owing to anatomical or technical problems, despite high reported success rates. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has recently emerged as an effective alternative biliary drainage method after unsuccessful ERCP. EUS-BD can be essentially divided ...

Learning endoscopic ultrasound (EUS) can be challenging as the technology combines disciplines of flexible endoscopy and diagnostic radiology. In early days evolution, radiographers performed EUS independently taught gastroenterologists basic principles ultrasound. Lok Tio developed first learning tool—an atlas EUS—by correlating images with computed tomography, surgery, pathology. Robert Hawes...

A subepithelial mass is a common finding during endoscopic procedures. Endoscopic ultrasound (EUS) is an important diagnostic modality in the evaluation of subepithelial lesions of the gastrointestinal tract. EUS is the diagnostic test of choice to assess the size, margins, the layer of origin, echotexture, and to differentiate between an intramural and extramural lesion. However, the EUS imagi...

Chin J Cancer Res 2014;26(6):644-646 www.thecjcr.org Endoscopic techniques in gastroenterology have been developing rapidly over the past two decades. Advances in minimally invasive endoscopic techniques allow for the detection and treatment of more gastrointestinal (GI) diseases than ever. In a manner of speaking, the advent of miniature ultrasound device coupled with endoscopy further shapes ...

The development of endoscopic ultrasound (EUS) since its introduction in the early 1980s has added greatly to the quality of imaging of the gastrointestinal tract. EUS is probably the investigation of choice for local staging of several gastrointestinal tumors and evaluation of submucosal masses. In addition to well-established indications, newer applications of EUS are emerging. For example, E...
