Background and study aims Endoscopic ultrasound (EUS) elastography (EUS-E) and contrast-enhanced harmonic EUS (CH-EUS) are useful methods for the diagnosis of pancreatic lesions. This study aims to compare the accuracy of combined EUS-E and CH-EUS with that of EUS-E or CH-EUS alone in the differential diagnosis of pancreatic solid lesions. Patients and methods One hundred thirty-six patient...
Implications of assessing the proximal and far para-tracheal or sub-carinal nodes (para-tracheal [PTN] or sub-carinal [SCN]) associated with lower primary esophageal carcinomas (ECs) are unclear. To evaluate the value of endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) for PTN and SCN, we analyzed results by positron emission tomography (PET) avidity, 4 EUS node malignancy features...
BACKGROUND Endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) and biopsy (FNB) is considered a very accurate and safe tool for sampling extra-intestinal tumors. Standard echoendosocopes for FNA/FNB are large with a sharpened tip that can be associated with complications. A new slim linearechoendoscope have been developed trying to overcome this limitation. AIM Of the present stud...
Introduction This guideline addresses the use of endoscopic ultrasound (EUS) as part of the diagnostic evaluation of certain conditions. In addition, issues of training and credentialing in EUS and complications of this procedure are also dealt with, within these guidelines. EUS combines features of endoscopy and ultrasonography in order to obtain structural information about organs within and ...
The prevalence of primary pericardial neoplasms ranges from about 0.001%– 0.007%. Primary malignant pericardial mesothelioma is extremely rare, with a reported prevalence of 0.0022% in autopsy series [1]. Although malignant mesothelioma is the most common primary malignancy of the pericardium, only approximately 350 cases of pericardial mesothelioma have been reported in the literature. Diagnos...
BACKGROUND This retrospective cohort study analyzes the potential risks associated with preoperative fine needle aspiration (FNA) biopsy guided by endoscopic ultrasonography (EUS) in patients undergoing distal pancreatectomy. METHODS Excluding 204 patients with acute or chronic pancreatitis and those with previous pancreatic resections, 230 consecutive patients with primary pancreatic neoplas...
BACKGROUND The use of emergency ultrasonography (EUS) has gained much popularity in the past few decades, and is now a mainstay of diagnostic decision-making. This expanded use is now highlighting the substantial issue of individual hospitals in credentialing its emergency medicine attending physicians in EUS in the United States. This issue is also of importance as more hospitals are now reque...
A 2-year-old Indian girl was referred with symptoms of biliary colic and obstructive jaundice of 3 weeks’ duration. Abdominal ultrasonography revealed dilation of intrahepatic biliary radicles, a distended gallbladder, and a dilated common bile duct (CBD) of 15mm (normal diameter up to 6mm) containing multiple ill-defined, oval, hyperechoic shadows near the lower end (▶Fig. 1). Magnetic resonan...
Endoscopic ultrasound (EUS)-guided biliary drainage is an increasingly popular technique for cases of previously unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). It has good results in expert hands, but is a challenging procedure with a significant rate of adverse events [1]. EUS-guided methylene blue cholangiopancreatography is a wireless alternative to the rendezvous techni...
EUS and EUS-FNA in the diagnosis of pancreatic carcinoma have been remarkably developed for last decade. High accuracies of EUS for T-staging especially in the diagnosis of portal venous involvement have been reported. In addition, at the same time, EUS-FNA can provide tissue diagnosis with high sensitivity and specificity. However, the utility of EUS in T-staging of pancreatic carcinoma is now...
