BACKGROUND: There is a lack of prospective, randomized studies comparing the
diagnostic yield and complication rates of 22-gauge and 25-gauge needles during EUS …

OBJECTIVES: The aim of this study was to evaluate the influence of on-site cytopathological
evaluation on the diagnostic yield of endoscopic ultrasound (EUS)-guided fine needle …

Background and study aims: The fanning technique for endoscopic ultrasound-guided fine-
needle aspiration (EUS–FNA) involves sampling multiple areas within a lesion with each …

Background and study aims: It is uncertain if needle gauge impacts the diagnostic accuracy
of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic mass …

Objective. It is controversial whether endoscopic ultrasound-guided fine needle aspiration
(EUS-FNA) is beneficial in all patients with suspected pancreatic cancer. The aim of this …

Objective: Pancreatic carcinoma is one of the leading cancer morbidity and mortality world-
wide. Controversy has arisen about whether the percutaneous approach with computed …

Since it was developed in 1992, endoscopic ultrasound‐guided fine needle aspiration (EUS‐
FNA) has been widely used and has been adapted for gastrointestinal and …

OBJECTIVES: A large-caliber needle such as a 19-gauge needle may help overcome the
limitations of a 22-gauge needle by acquiring a larger amount of tissue sample. However …

Background Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with rapid on-
site evaluation (ROSE) has been reported to provide a more accurate diagnosis than EUS …

Endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) is widely used for
diagnosis of pancreatic lesions. The Echotip Procore Needle (Wilson‐Cook Medical) is a …
