AIM: To evaluate endoscopic ultrasound (EUS)-guided biopsies for the pretreatment characterization of gastrointestinal stromal tumors (GIST) to personalize the management of patients. METHODS: All patients with lesions suspected to be GIST who were referred for EUS-sampling at a tertiary Swedish center were eligible for inclusion 2006-2015. During the observational study phase (2006-2011), routine fine-needle-aspiration (EUS-FNA) was performed. In 2012-2015, we converted to an interventional, randomized protocol with dual sampling EUS-FNA and fine-needle-biopsy-sampling (EUS-FNB) for all lesions...

RATIONALE: Pancreatic acinar cell carcinoma (ACC) is a rare malignant tumor of exocrine pancreas. It is typically a well-marginated large solid mass arising in a certain aspect of the pancreas. Diffuse involvement of ACC in the pancreas is very rare, and may simulate pancreatitis in radiological findings. We report 2 cases of ACC presenting as diffuse enlargement of the pancreas due to tumor involvement without formation of a distinct mass. PATIENT CONCERNS: The patients consisted of a 41-year-old man with weight loss and a 77-year-old man who was asymptomatic...

A 56-year-old man presented with a chest computed tomography (CT) finding of a right upper lobe nodule, which was diagnosed using brush cytology as adenocarcinoma stage IB (cT2aN0M0). Repeat CT scan for preoperative evaluation revealed a small, slightly hypodense spot in the pancreatic body, which was diagnosed as pancreatic metastasis from lung cancer using endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB). Because of the presence of distant metastasis, surgical resection was deferred and chemotherapy was chosen instead...

Background and study aims  Tumor seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is rare. A 53-year-old man underwent transesophageal EUS-FNA for diagnosis of a 6-cm mass in the mediastinum as seen by computed tomography (CT). Four weeks later, repeat CT scan revealed a mass in the esophageal wall. Upper gastrointestinal endoscopy confirmed a lesion in the mid-esophagus, which was biopsied and found to be consistent with needle tract seeding after EUS-FNA. Tumor seeding in the gastrointestinal wall or peritoneum after EUS-FNA is rare, but may adversely affect the prognosis...

An 80-year-old man presented with a right side lung tumor. The tumor was not abutting the bronchus or chest wall; thus, endobronchial ultrasound (EBUS) and CT-guided biopsy were considered to be technically difficult. We therefore attempted endoscopic ultrasound-guided fine needle aspiration (EUS-FNA). Although the nodule was not abutting the esophagus on CT, an irregularly shaped hypoechoic lesion was visualized on EUS. EUS-FNA was successfully performed. The tumor was diagnosed as squamous cell carcinoma...

Endoscopic ultrasound (EUS)-guided tissue acquisition has greatly evolved since the first EUS-guided fine-needle aspiration was reported nearly 25 years ago. EUS-guided tissue acquisition has become the procedure of choice for sampling of the pancreas, subepithelial lesions, and other structures adjacent to the gastrointestinal tract. This review focuses on recent developments in procedural techniques and needle technologies for EUS-guided tissue acquisition.

Conventional endoscopic ultrasonography (EUS) has limitations in the diagnosis of solid masses. Because most are depicted as a hypoechoic mass, without cytology or biopsy, it can be difficult to distinguish inflammatory masses from malignancy. Recently developed, contrast-enhanced harmonic EUS (CH-EUS) has improved characterization of digestive lesions by depicting microvessels and parenchymal perfusion, particularly for differentiating pancreatic cancer from other pancreatic solid lesions, identifying mural nodules in intraductal papillary mucinous neoplasms, and estimating malignant potential of gastrointestinal stromal tumors...

BACKGROUND AND AIMS: Despite the widespread use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and the standardization of pancreaticobiliary cytopathologic nomenclature, data on interobserver agreement (IOA) amongst cytopathologists evaluating pancreatic tissue specimens are limited. We aimed to assess IOA among cytopathologists evaluating EUS-FNA specimens of solid pancreatic lesions for overall cytologic diagnosis and quantitative and qualitative parameters using a novel standardized scoring tool and to evaluate predictors of agreement...

A 66-year-old man was referred to our hospital with an increasing subepithelial lesion in the gastric antrum. Using esophagogastroduodenoscopy, a tumor with a steep, 20-mm-high rise protruding in the lumen was observed. The mucosal surface of the tumor was reddish, with ulcers forming at the base. Moreover, the tumor was mobile and soft. A biopsy specimen was taken from the ulcer, but tumor tissue was not collected from the submucosa. Endoscopic ultrasonography (EUS) showed a high echoic mass in the submucosa...

Primary squamous cell carcinoma (SCC) of the rectum is a very rare entity making up to 0.1-0.25/1,000 cases of all colorectal cancers. Here, we present the case of an otherwise healthy 63-year-old female who presented with progressive pelvic discomfort, new onset constipation and a complex mass in presacral region on imaging which was proved to be poorly differentiated SCC of the rectum. The correct diagnosis was achieved by fine needle aspiration (FNA) via endoscopic ultrasound (EUS-guided FNA) as initial conventional colonoscopy failed to establish the diagnosis...

The International Consensus Diagnostic Criteria (ICDC) for the diagnosis of autoimmune pancreatitis (AIP) include the histological criterion that is based on either pancreatic core needle biopsies (CNBs) or surgical specimens. However, CNBs are difficult to obtain by endoscopic ultrasound (EUS). EUS fine-needle aspiration (EUS-FNA) cytology is usually not sufficient for the diagnosis of AIP, but may sometimes contain tissue microfragments. Another approach is EUS-guided histological fine-needle biopsy (EUS-FNB), using needles such as the SharkCore or ProCore needle...

BACKGROUND: Fine-needle aspiration (FNA) of focal splenic lesions (FSL) is usually done under ultrasound (US) or computed tomography guidance. Endoscopic US (EUS), because of its ability to provide high-resolution images, can be used for aspirating FSL. We studied the safety and efficacy of EUS-guided FNA of FSL. METHODS: We performed a retrospective analysis of patients with FSL undergoing EUS-guided FNA over the last six years. RESULTS: EUS-guided FNA was performed in 16 patients (age: 28-43 years; male: 11)...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) plays a key role in the staging of lung cancer, which is crucial for allocation to surgical treatment. EBUS-TBNA is a complicated procedure and simulation-based training is helpful in the first part of the long learning curve prior to performing the procedure on actual patients. New trainees should follow a structured training programme consisting of training on simulators to proficiency as assessed with a validated test followed by supervised practice on patients...

BACKGROUND AND OBJECTIVES: With improvements in imaging technologies, pancreatic cystic lesions (PCLs) have been increasingly identified in recent years. However, the imaging modalities used to differentiate the categories of pancreatic cysts remain limited, which may cause confusion when planning treatment. Due to progress in endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) technology, auxiliary diagnosis by the detection of cystic fluid has become a recent trend. METHODS: From March 2015 to April 2016, 120 patients with PCLs were enrolled in this study...

BACKGROUND: Ectopic pancreas (EP) belongs to the most frequent subepithelial lesions (SELs) of the upper gastrointestinal (GI) tract. In the majority of cases, it is detected incidentally. Differential diagnosis from mesenchymal subepithelial tumors may be difficult. METHODS: Among 24,308 endosonographic examinations and interventions, which were prospectively enrolled in the database of the German Endoscopic Ultrasound (EUS) Registry from January 2009 to August 2013, 575 were performed for suspected SELs of the upper GI tract...
