Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA), though a well-established method for specimen acquisition from pancreatic neoplasm, has a limited role for non-focal benign pancreatic diseases such as autoimmune pancreatitis (AIP) due to sample inadequacy and architectural distortion. Core biopsies through EUS-trucut biopsy (EUS-TCB) or newer generation EUS-fine needle biopsy (EUS-FNB) enable better histopathologic review through...
