To overcome the limitations of using cytological specimen alone for the diagnosis of challenging pancreatic lesions, biopsy needles have been developed to procure histological specimens during EUS, especially for the discrimination of several specific pancreatic tumors requiring adequate histological samples. The aim of this study was to compare the diagnostic yield of EUS-guided 22-gauge (G) fine needle aspiration (FNA) needles and 22G fine needle biopsy (FNB) needles for sampling pancreatic masses.

BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been used for detecting pancreatic cancer. We aimed to compare the diagnostic yield of both 22-gauge and 25-gauge EUS-FNA f...
Several studies have compared EUS fine-needle aspiration (FNA) with biopsy (FNB) needles, but none has proven superiority. We performed a multicenter randomized controlled trial to compare the perform...
Molecular data has become an essential part of the updated World Health Organization (WHO) grading of central nervous system tumors. However, stereotactic needle biopsies provide only small volume spe...
Biopsy needles are standard medical devices for extracting biological tissue with the purpose of diagnosing a specific anomaly such as cancerous masses, or lumps. The outcome of these procedures great...
Fine needle aspiration (FNA) cytology has been the preferred technique for procuring tissue at endoscopic ultrasound (EUS) procedures for the past 25 years. To overcome some of the limitations of FNA ...
Rationale: Until now there are no prospective studies comparing the 22 gauge and 25 gauge side-fenestrated and fork-tip needles. In the present study we will compare the two types of need...
This observational study compared quality of histological sampling of pancreatic EUS-FNB with the 20-gauge Procore® and 22-gauge Acquire® needles. In total, 68 patients were recruited. H...
Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is a valid and recommended technique for tissue diagnosis of pancreatic masses. However, the diagnostic yield is with a sensitivit...
To investigate the technical feasibility and diagnostic yield of new 20-gauge Procore needle for EUS-guided fine needle biopsy in pancreatic solid lesions.
This study evaluates the yield and safety of two different needles for performing endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) in patients with sarcoidosis....
The use of needles usually larger than 14-gauge to remove tissue samples large enough to retain cellular architecture for pathology examination.
Using fine needles (finer than 22-gauge) to remove tissue or fluid specimens from the living body for examination in the pathology laboratory and for disease diagnosis.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Conducting a biopsy procedure with the aid of a MEDICAL IMAGING modality.
A diagnostic procedure used to determine whether LYMPHATIC METASTASIS has occurred. The sentinel lymph node is the first lymph node to receive drainage from a neoplasm.
Pancreatitis Acute pancreatitis is inflammation of the pancreas caused by the release of activated pancreatic enzymes. Common triggers are biliary tract disease and chronic heavy alcohol intake. Diagnosis is based on clinical presentation...
The pancreas secretes a number of important hormones into the digestive tract and the blood stream. Cancers are most commonly exocrine than endocrine (neuroendocrine) tumors. Functional tumors secrete hormones; Insulinoma, Gastrinoma, Somatostatinoma, VI...
