The presacral, or pararectal, space is a potential site for the formation of various cysts and tumors, since it contains variety embryonic tissues. Magnetic resonance imaging principal method diagnosis presacral cysts, endoscopic ultrasonography an auxiliary method. These masses are subject to surgical removal, even in cases asymptomatic course. paper presents successful experience treating 3 p...

Endoscopic Ultrasonography (EUS) in patients with suspected bile duct stones rules out the presence of up to 65% patients, thus preventing unnecessary Retrograde Cholangiography Sphincterotomy (ERC ES) and its complications majority cases.1 Increased use EUS for ruling has led more cases which sludge is detected. Sludge an ultrasound diagnosis usually described as layered, mobile, low-amplitude...

Gastric stromal tumors are rare neoplasms of the stomach. In this report we present a gastric stromal tumor with an exophytic growth pattern, and describe magnetic resonance imaging and endoscopic ultrasonography findings.

BACKGROUND Accurate staging of pancreatic cancer is essential for surgical planning and for identification of locally advanced and metastatic disease that is incurable by surgery. Advances in endoscopic sonography (EUS), computed tomography (CT), and positron emission tomography have improved the accuracy of staging and reduced the number of incomplete surgical resections. Tissue acquisition is...

Endoscopic ultrasonography (EUS) is widely used to evaluate pancreaticobiliary diseases, especially pancreatic masses. EUS has a good ability to detect pancreatic masses, but it is not sufficient for the differential diagnosis of various types of lesions. In order to address the limitations of EUS, new techniques have been developed to improve the characterization of the lesions detected by EUS...

BACKGROUND AND OBJECTIVES Due to the increasing use of endoscopic techniques for colon cancer resection, pretreatment locoregional staging may gain critical interest. The use of endoscopic ultrasonography (EUS) miniprobes in this context has been seldom reported. Our aim was to determine the accuracy of EUS miniprobes for colon cancer staging. MATERIALS AND METHODS Forty patients with colon c...

OBJECTIVES To investigate the usefulness of contrast-enhanced endoscopic ultrasonography (CE-EUS) for histological differentiation of pancreatic tumors. METHODS CE-EUS was performed for consecutive patients having a pancreatic solid lesion, and tumors were classified into three vascular patterns (hypervascular, isovascular, and hypovascular) at two time phases (early-phase and late-phase). Co...

BACKGROUND EUS is complicated because of the subtleties of US interpretation, small fields of observation, and uncertainty of probe position and orientation. OBJECTIVE Improved EUS performance is sought by providing contextual information to support US probe positioning and identification of features in US images. Our aims were to demonstrate the feasibility of the image registered gastroscop...

The inspection of the liver is a valuable part of the upper endoscopic ultrasonography (EUS) studies, regardless of the primary indication for the examination. The detailed images of the liver segments provided by EUS allows the use of this technique in the study of parenchymal liver disease and even in the diagnosis and classification of focal liver lesions. EUS has also emerged as an importan...
