Endoscopic ultrasound (EUS)-guided tissue acquisition is an indispensable technique for the diagnosis of many diseases of the gastrointestinal tract and adjacent structures. EUS-guided fine-needle aspiration (EUS-FNA) is known for its high accuracy and low complication rate. However, the outcome of EUS-FNA highly depends on several factors such as the location and characteristics of the lesion,...

Background: The diagnostic yield and safety of trans-gastric EUS-guided FNA of the left adrenal gland are not well defined. Methods: All patients with an enlarged left adrenal gland on abdominal imaging and known or suspected malignancy referred to two EUS centers over a 3-year period were included in this study. EUS-guided FNA was performed on an outpatient basis by one of 4 experienced endoso...

Frontline Gastroenterology Published Online First: [please include Day Month Year] doi:10.1136/flgastro-2016100759 INTRODUCTION Linear endoscopic ultrasound (EUS) has become established as a key diagnostic and therapeutic tool in pancreaticobiliary medicine over the last 20 years. EUS/ EUS-fine needle aspiration (FNA) is used in the diagnosis and staging of pancreatic and bil...

Background. There is a high incidence of inconclusive cytopathology at initial EUS-FNA (endoscopic ultrasound-guided fine-needle aspiration) for suspected malignant pancreatic lesions. To obtain appropriate preoperative or palliative chemotherapy for pancreatic cancer, definitive cytopathology is often required. The utility of repeat EUS-FNA is not well established. Methods. A retrospective coh...

OBJECTIVE To determine the contribution of percutaneous cutting needle biopsy (PNB) subsequent to fine-needle aspiration (FNA) in the diagnosis of chest lesions. DESIGN A retrospective review of 220 patients who underwent CT-guided FNA followed immediately by PNB performed at our center between 1988 and 1995 was undertaken. Thirty-eight patients were excluded because FNA and/or PNB specimens ...

CONTEXT Pancreatic involvement in systemic light chain (AL)-amyloidosis is exceedingly rare. Prior reports of endoscopic ultrasound (EUS) for the diagnosis of amyloidosis are also limited. CASE REPORT We report the first description of EUS-guided fine needle aspiration (FNA) for the diagnosis of primary AL-amyloidosis involving the pancreas. CONCLUSION EUS-FNA can be effectively utilized fo...

The solid pseudopapillary tumor (SPT) of the pancreas is a rare but low-grade malignant tumor with a good prognosis after surgical excision. Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) is a minimally invasive, safe and reliable way of diagnosing SPT by providing characteristic cytological and immunochemical specimens. Definitive preoperative diagnosis leads to targeted and m...

Biliary strictures may be due to a variety of benign and malignant processes. Imaging with endoscopic ultrasonography (EUS) often suggests the diagnosis, but is usually not definitive. EUS-guided fine needle aspiration (FNA) facilitates the diagnosis of extrahepatic biliary strictures, although peritioneal metastases due to needle tract seeding may occur after EUS-FNA of cholangiocarcinoma. In ...

Compared to other imaging modalities, endoscopic ultrasound (EUS) has limitations in terms of image enhancement. However, with the availability of contrast agents in ultrasonography, EUS has evolved. Contrast-enhanced Doppler EUS (CD-EUS) enhances Doppler signals from vessels and is useful for characterizing lesions detected by EUS. Moreover, contrast-enhanced harmonic EUS (CH-EUS) with second-...
