Background and aims Preoperative diagnostic imaging of pancreatic solid pseudopapillary neoplasms (SPN) is challenging. A few studies have investigated the role of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for the diagnosis of SPN. We investigated the diagnostic yield of cell blocks and immunohistochemistry (IHC) for SPN using EUS-FNA specimens without cytological evaluation. Patients and methods We retrospectively analyzed the histopathology records of patients with suspecte...

: Pancreatic cystic lesions (PCLs) have been increasingly recognized in clinical practice. Although inflammatory cysts (pseudocysts) are the most common PCLs detected by cross-sectional imaging modalities in symptomatic patients in a setting of acute or chronic pancreatitis, incidental pancreatic cysts with no symptoms or history of pancreatitis are usually neoplastic cysts. For these lesions, it is imperative to identify mucinous cysts (intraductal papillary mucinous neoplasms and mucinous cyst...

Summary Background and study aims Acute pancreatitis has no obvious cause after clinical, laboratory and radiologic investigation in 10%–30% of patients, and the diagnosis of idiopathic pancreatitis is given. This study investigated the role of linear EUS for identification of possible causes for acute pancreatitis when other investigative methods failed. Patients and methods Between June 2012 and March 2017, 35 patients [25 women; mean age: 51.9 + 17.8 years] with idiopathic acute pancreatitis ...

OBJECTIVES:To evaluate the diagnostic yield of the cell block (CB) technique with immunohistochemistry in patients with mesenchymal neoplasms of the gastrointestinal tract collected by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). METHODS:Tissue samples from consecutive patients with subepithelial lesions collected by EUS-FNA, without analysis by on-site cytopathology, were evaluated by the same pathologist only using CBs in AAF fixative. Sections were stained with haematoxylin-...

BACKGROUND: Tissue diagnosis is required for gastric subepithelial lesions for differential diagnosis of GISTs. However, there has not been consensus about the best needle for EUS-guided sampling of these lesions. AIM: To evaluate the diagnostic yield of EUS-FNA for gastric subepithelial lesions of the proper muscle layer with large-bore 19 gauge needles. METHODS: A prospectively maintained database was retrospectively reviewed to identify consecutive patients who underwent EUS-FNA with 19 and 2...

Different options of endosonography-guided biliary drainage after endoscopic retrograde cholangio-pancreatography failure
Source
The subject of this study was a thirty-two–year-old female patient presenting nausea and no other symptoms at the clinical examination. The physical examination was unremarkable. The laboratory tests including tumor markers were normal. We performed routine exams where an abdominal ultrasound US identified a solid lesion in the body of the pancreas. An abdominal Magnetic Resonance Imaging was performed, which delimited the lesion and subsequent endoscopic ultrasound EUS evaluation for the histol...

Background and Objectives: At the time of its introduction in the early 80s, endoscopic ultrasonography (EUS) was indicated for diagnostic purposes. Recently, EUS has been employed to assist or to be the main platform of complex therapeutic interventions. Methods: From a series of relevant new topics in the literature and based on the need to complement the I Brazilian consensus on EUS, twenty experienced endosonographers identified and reviewed the pertinent literature in databases. The quality...
