This randomized study investigates two different diagnostic strategies for patients with suspected pulmonary sarcoidosis stage I/II. The objective is to assess the role of endosonography ...
The purpose of the study is to determine the best evaluation for patients with idiopathic (unexplained) pancreatitis, we are evaluating the role of endoscopic ultrasonography given that th...
To evaluate the feasibility of EUS-FNA for patients taking anticoagulants without heparin bridge.
Quantificational Enhancement Pattern Analysis Using a Novel Software "Vuebox" of Contrast-enhanced Harmonic Endoscopic Ultrasonography for Differential Diagnosis Between Adenomas and Cholesterol Polyps
The investigators' study is a prospective study to evaluate the enhancement pattern of contrast-enhanced endoscopic ultrasonography and suggest the criterions for differential diagnosis be...
Patients with non-resectable pancreatic cancer have a poor prognosis.The analysis of prognostic factors before treatment may be helpful in selecting appropriate candidates for chemotherapy...
We aimed to investigate the roles of endoscopic ultrasonography (EUS) and magnetic resonance cholangiopancreatography (MRCP) in detecting the causes of acute pancreatitis after negative computed tomog...
to determine the role of endoscopic ultrasonography (EU) in comparison with nuclear magnetic resonance imaging (MRI) and examination under anesthesia (EUA) in the management of patients with perianal ...
The last decade has seen a dramatic rise in the possibilities of therapeutic endoscopic ultrasound (EUS). From EUS fine needle aspiration of cancerous lesion to pseudocyst drainage, it has now not onl...
To compare endoscopic ultrasonography (EUS) and magnetic resonance imaging (MRI) in terms of their sensitivities to localize pancreatic neuroendocrine tumors (pNET) preoperatively. Systematic analysis...
Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
Conducting a fine needle biopsy with the aid of ENDOSCOPIC ULTRASONOGRAPHY.
Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Fiberoptic endoscopy designed for duodenal observation and cannulation of VATER'S AMPULLA, in order to visualize the pancreatic and biliary duct system by retrograde injection of contrast media. Endoscopic (Vater) papillotomy (SPHINCTEROTOMY, ENDOSCOPIC) may be performed during this procedure.
Incision of Oddi's sphincter or Vater's ampulla performed by inserting a sphincterotome through an endoscope (DUODENOSCOPE) often following retrograde cholangiography (CHOLANGIOPANCREATOGRAPHY, ENDOSCOPIC RETROGRADE). Endoscopic treatment by sphincterotomy is the preferred method of treatment for patients with retained or recurrent bile duct stones post-cholecystectomy, and for poor-surgical-risk patients that have the gallbladder still present.
