Multi-center Prospective Evaluation of the Diagnostic Yield of Endoscopic Ultrasound-Guided Tissue Sampling
All patients will receive standard medical care and no experimental interventions will be
performed. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a
well-established procedure commonly used for the investigation of lesions within or adjacent
to the gastrointestinal (GI) lumen (i.e. pancreas, liver, mediastinal masses, left adrenal
gland, lymph nodes, and subepithelial lesions). EUS-guided tissue sampling has been commonly
performed with different size and types of aspiration and core biopsy needles.

size and types of aspiration and core biopsy needles. More recently, a novel
through-the-needle microforceps has been introduced. The MorayTM microforceps fits through a
19-gauge FNA needle and allows targeted tissue sampling under EUS visualization.
Aim - To prospectively evaluate the safety and diagnostic yield of the through-the-needle
microforceps for pancreatic and non-pancreatic solid, cystic and mixed solid/cystic lesions.
