BACKGROUND AND AIMS: There are no systematic reviews comparing the use of endoscopic retrograde cholangiopancreatography (ERCP)-based brush cytology and forceps biopsy and endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for the diagnosis of malignant biliary stricture; so in this revision, we will compare ERCP against EUS-FNA for tissue diagnosis of malignant biliary stricture. DESIGN: A systematic review was conducted of comparative studies (prospective or retrospective) analyzing EUS and ERCP for tissue diagnosis of malignant biliary stricture...

Dynamic contrast-enhanced ultrasound (DCE-US) has been recently standardized by guidelines and recommendations. The European Federation of Societies for US in Medicine and Biology position paper describes the use for DCE-US. Comparatively, little is known about the use of contrast-enhanced endoscopic US (CE-EUS). This current paper reviews and discusses the clinical use of CE-EUS and DCE-US. The most important clinical use of DCE-US is the prediction of tumor response to new drugs against vascular angioneogenesis...

The porta hepatis and hepatoduodenal ligament (HDL) are important anatomical pathways of extension of disease to and from the liver. The imaging of this area is difficult. The role of endoscopic ultrasound (EUS) as an imaging modality for hepatoduodenal ligament has not been established so far. All images in the present study have been generated from a detailed review of real time recordings using the curved linear scanning echoendoscope EG -3830 UT (Pentax Corporation, Tokyo, Japan), coupled with a Hitachi avius and Hitach 7500 processor (Hitachi Aloka Medical, Tokyo Japan)...

Dysphagia can occur due to extrinsic compression on esophagus. Dysphagia due to intrathoracic vascular causes is rare. Most reported cases of vascular etiology are due to dysphagia lusoria. Dysphagia due to any anomaly of aorta is called dysphagia aortica. In an emergency setting, endoscopic ultrasound (EUS) has been found to be superior and more sensitive for detection of abdominal aortic aneurysms over conventional radiological methods. We present a series of four cases of dysphagia aortica where the diagnosis was made by endoscopic ultrasound...

Lung cancer is one of the major causes of death in the world. Small cell carcinoma is the most aggressive type and can spread rapidly. The association of a small cell carcinoma with hepatic hilar metastasis and biliary obstruction is rare. Endoscopic ultrasound allows the aspiration of a cytology sample from adenopathies for diagnostic purpose. We present the case of a patient with lung cancer, with lymph node metastasis to the hepatic hilum and extrinsic biliary tree compression. Endoscopic ultrasound allowed the definitive diagnosis of hepatic hilar metastasis of a lung small cell carcinoma...

So Nakaji, Nobuto Hirata
A 71-year-old female was diagnosed with hepatocellular carcinoma (HCC). The tumor measured 65 mm in diameter and was located in the caudate lobe. Transarterial chemoembolization (TACE) was performed repeatedly; however, a follow-up dynamic computed tomography (CT) scan showed that the tumor remained viable. Thus, TACE was performed using drug-eluting beads that had been preloaded with epirubicin. Contrast-enhanced endoscopic ultrasonography (CE-EUS) was conducted for evaluating the treatment effects. First, we detected the internal part of the tumor...

BACKGROUND AND OBJECTIVES: Contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) is a novel technology that can identify subepithelial tumors (SETs) by detecting the degree of enhancement, but whether CEH-EUS can predict the malignancy risk of gastrointestinal stromal tumors (GISTs) remains unclear. The aim of our study was to evaluate the diagnostic accuracy of CEH-EUS and its ability to discriminate among SETs and predict the malignancy risk of GISTs. MATERIALS AND METHODS: We retrospectively included patients with suspected subepithelial lesions who underwent CEH-EUS preoperatively...

BACKGROUND AND OBJECTIVES: There have been few studies to date evaluating the effectiveness of contrast-enhanced endoscopic ultrasound (CE-EUS) for detecting mural nodules in patients with branch duct-type intraductal papillary mucinous neoplasm (BD-IPMN) of the pancreas. We aim to evaluate the effectiveness of CE-EUS for detecting mural nodules in BD-IPMN. PATIENTS AND METHODS: Of the 427 BD-IPMN patients, 21 patients (4.9%) in whom the presence of mural nodules was suggested by CE computed tomography (CT) or magnetic resonance imaging (MRI), or in whom the presence of nodule-like lesions as shown by fundamental EUS, were examined by CE-EUS...

Maxime Palazzo
Contrast harmonic endoscopic ultrasonography (CH-EUS) is a new technique which allows the dynamic study of the microvascularization of a target tissue. Its application is validated for the diagnosis of pancreatic adenocarcinoma but remains unclear for other solid pancreatic tumors (neuroendocrine tumors [NETs], autoimmune pancreatitis [AIP], metastases). The purpose of this review is to outline the potential role of the CH-EUS in these indications. NETs are typically iso/hyperenhanced at CH-EUS, and a heterogeneous enhancement seems a good predictor of malignancy in neuroendocrine pancreatic tumor...

Contrast-enhanced endoscopic ultrasound (CE-EUS) allows characterization, differentiation, and staging of focal pancreatic masses. The method has a high sensitivity and specificity for the diagnosis of pancreatic adenocarcinoma which is visualized as hypo-enhanced as compared to the rest of the parenchyma while chronic pancreatitis and neuroendocrine tumors are generally either iso-enhanced or hyper-enhanced. The development of contrast-enhanced low mechanical index harmonic imaging techniques used in real time during endoscopic ultrasound (EUS) allowed perfusion imaging and the quantification of intensity of the contrast signal through time-intensity curve analysis...

REVIEW

With the widespread use of endoscopy, gastrointestinal submucosal lesions are now more commonly discovered. Although endoscopic ultrasound (EUS) is superior to all other imaging techniques for the diagnosis of submucosal tumors (SMTs), it is still suboptimal for differentiating hypoechoic lesions arising from the fourth sonographic gastrointestinal wall layer, which encompass tumors with very different prognosis. EUS tissue acquisition has provided with the unique opportunity to obtain histological confirmation, but it is not accurate enough to evaluate the malignant potential of gastrointestinal stromal tumors (GISTs)...

Endoscopic ultrasound (EUS) plays an important role in imaging of the mediastinum and abdominal organs. Since the introduction of US contrast agents (UCA) for transabdominal US, attempts have been made to apply contrast-enhanced US techniques also to EUS. Since 2003, specific contrast-enhanced imaging was possible using EUS. Important studies have been published regarding contrast-enhanced EUS and the characterization of focal pancreatic lesions, lymph nodes, and subepithelial tumors. In this manuscript, we describe the relevant UCA, their application, and specific image acquisition as well as the principles of image tissue characterization using contrast-enhanced EUS...
