Fine needle aspiration biopsy guided by ultrasonography was performed in 39 patients with pancreatic cancer to evaluate the value of the technique for establishing a proved histologic diagnosis. Aspirated material suitable for cytologic evaluation of smear preparation was obtained from 33 patients (84.6%). Among the 33 patients, cytologic diagnosis of pancreatic cancer was possible in 28 patien...

BACKGROUND The comparison between endoscopic ultrasound guided fine needle aspiration (EUS-FNA) and endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for the diagnosis of pancreatic masses is still controversial. Many factors can affect the final results. METHODS Databases, such as PubMed, EMBASE, Cochrane Library, and Science Citation Index updated from 2000 to 2016 were searched to ...

Extramedullary plasmacytoma involves organs outside the bone marrow; however, involvement of the pancreas is rare. We recently experienced a case of extramedullary plasmacytoma of the pancreas that was diagnosed by endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). EUS-FNA, which has a high diagnostic accuracy and an excellent safety profile, is the modality of choice for estab...

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has evolved to become an indispensable tool for tissue acquisition. While the overall diagnostic accuracy of EUS-FNA is greater than 90% for lung cancer staging, it is lower for pancreatic mass lesions. Several factors such as location of the tumor, disease characteristics and procedural techniques determine the outcomes of EUS-FNA. ...

Introduction Ultrasound guided fine needle aspiration biopsy of abdominal masses is an increasingly common diagnostic procedure in oncology. Various imaging modalities like lymphography, fluoroscopy and computerized tomography (CT) have been utilized in the evaluation of abdominal masses. The advantages of ultrasono-graphy is that it is rapid, inexpensive, versatile, no ionizing radiation is ap...

BACKGROUND Puncture biopsy and fine needle aspiration guided by endoscopic ultrasound has been used as an effective technique and is quickly becoming the procedure of choice for diagnosis and staging in patients suspected of having pancreatic cancer. This procedure has replaced retrograde cholangiopancreatography and brush cytology due to its higher sensitivity for diagnosis, and lower risk of ...

Endoscopic transmural drainage by using endoscopic ultrasound (EUS) guidance is not always safe because of the risk of bleeding and perforation. Additionally, the effective area of the EUS-guided procedure using a large diameter needle is relatively narrow. We evaluated the effectiveness and safety of EUS-guided drainage using fine needle and stiff fine guidewire without electrocautery. From No...

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 A solid pseudopapillary tumour of the pancreas (SPTP) is a rare neoplasm. AIM We herein present five cases of SPTP diagnosed using endoscopic ultrasound (EUS) guided fine-needle biopsy (FNB) using a needle with side fenestration (ProCore-needle). METHODS From January 2011 to June 2012 in five patients with SPTP tissue acquisition was carried out with a 19-gauge (4 patients) or a ...

results in the first series, cellularity and blood levels were significantly lower in capillary-fnb compared with cfnb (p < 0.001 and p = 0.011, respectively). there was no significant difference between cfnb and vacfnb in cellularity and blood (p = 0.15 and p = 0.1, respectively). in the second series, cellularity was significantly higher in cfnb compared with vacfnb (p < 0.001) with no signif...
